From the DoK Day EU 2022 (https://youtu.be/Xi-h4XNd5tE)
The container storage interface (CSI) is a contract between different container orchestrators (Kubernetes, Nomad, etc) and storage plugins. This contract is a set of gRPC services for provisioning, utilizing, and snapshotting storage volumes. In this talk, we will focus on one aspect of the CSI spec: Volume Snapshots.
The talk will cover volume snapshots on Kubernetes CSI, with a deep dive on Kubernetes CSI snapshots. A short demo on the basics of the CSI snapshots on Kubernetes will help show how easy it is to start using CSI snapshots.
After covering the basics on both container schedulers, we’ll deep dive into how backup systems can programmatically interact with the Kubernetes CSI snapshots client. This example will be based on Stork, an open-source backup system that has implemented the CSI spec.
I believe this talk will be beneficial to the community because it covers some storage-related topics that have not been covered much in previous conferences. I’m hoping to bring the unique perspective of a Kubernetes CSI and Nomad CSI contributor, while also covering the CSI plugin maintainer and end-user perspective. With this wide audience, many conference attendees will be able to learn about stateful applications, CSI volume snapshots, and developing CSI drivers for any container scheduler.
Grant Griffiths is a core contributor and reviewer for the Kubernetes CSI and SIG Storage communities working at Portworx. For kubernetes-CSI, he helped bring the external-snapshotter to Beta in Kubernetes 1.17 and GA in Kubernetes 1.20, improved support for secrets, release tooling, and fixed various snapshot controller bugs. At Portworx, he works on control plane components such as the CSI Driver, SDK, CLI, and security. Previously, Grant was a Senior Software Engineer at GE Digital where he built Data Services in Go on k8s.

Our data workloads, however, have run instead in AWS Glue. This has worked well enough for the reporting use cases that have been the main focus of this team historically. However, at the beginning of 2022, the PayIt data team began building out a new data platform, and in the process, ran into a number of challenges with Glue. In this talk, I will share the difficulties that we encountered with building, deploying, and orchestrating ETL pipelines in AWS Glue, our decision process for moving those workloads into Kubernetes, and the ELT architecture that we’ve arrived at today.

What’s more, cloud native environments are becoming more and more expensive to operate and manage, as well as increasingly difficult to secure. On the bright side, there is a growing ecosystem of exceptional open source tools to help overcome this complexity, and provide greater situational awareness to what’s happening in your many and multiple Kubernetes clusters. In this talk, we’ll take a deep dive on how to understand everything that is happening with stateful workloads in your Kubernetes clusters from health to security - including the management and monitoring of your clusters, troubleshooting and debugging, through full security scanning in multiple data perspectives- from configMaps, Secrets, hostPaths and many more security driven checks for proper role-based access control, vulnerabilities and misconfigurations. We will demonstrate how you can have a 360º-view of your Kubernetes clusters in a single open source dashboard leveraging tools like Lens and Kubescape, and ultimately enforce policies with Open Policy Agent.…

הפעל מאוחר יותר הפעל מאוחר יותר רשימות לייק אהבתיFrom the DoK Day North America 2022 ( https://youtu.be/YWTa-DiVljY ) Video - https://youtu.be/LymPjH6HA3E ABSTRACT Stateless apps are easy to manage. More often than not, a Kubernetes Deployment, with a Service, Ingress, and Horizontal Pod Autoscaler (HPA) is enough. Almost everyone can do it. But, when it comes to stateful applications, things become a bit more complicated. We might need a database and storage. We might need to manage database users and schema. We might need to consider quite a few other things. Stateful apps are harder for everyone, especially if we want to shift left and enable developers to do it themselves. In this talk, we'll try to make the management of stateful applications easy for everyone. We'll accomplish that by creating easy-to-consume services that are made specifically for the needs of our organizations. We'll see how to create new Kubernetes Custom Resource Definitions (CRDs) and controllers using Crossplane. Those controllers will envelop all the tools, resources, and processes we might need. As a result, ops can focus on creating such services while everyone else can consume them (create and manage everything related to stateful apps) without opening JIRA tickets and waiting for others to complete their tasks.…

הפעל מאוחר יותר הפעל מאוחר יותר רשימות לייק אהבתיFrom the DoK Day North America 2022 ( https://youtu.be/YWTa-DiVljY ) ABSTRACT Healthcare organizations are transforming their applications and embracing digital platforms for efficient patient care. Today, compute at the edge, plays a critical role in deploying innovative healthcare applications that promise new approaches to patient care. Connected care platforms at scale are turning to Kubernetes infrastructure for deployment of telehealth and telemedicine apps. These kinds of applications often need real time image processing and inferencing at the edge, which in turn, require a distributed application platform on Kubernetes. They also need secure foundations for a regulatory compliant framework for wider adoption. To elaborate further, a distributed platform or a multi-cluster infrastructure is necessary for healthcare applications. All medical application platforms are data intense. For eg. Medical applications that need to stream video data, i.e move large quantities of data need secure connections from edge to cloud. Smart healthcare applications are also seeing the value of multi-cloud deployments. The ability to choose different technologies like AI, data storage systems or some specific relational database systems is driving multi-cloud adoption in healthcare solutions. A multi-cluster connectivity fabric is thus needed for data intensive healthcare applications to distribute across geographical boundaries. The fabric needs to have inbuilt automation and the smarts to make the best use of compute resources in a distributed infrastructure, for improved patient healthcare.…

As more and more organizations move stateful workloads to Kubernetes, we’ve started to see these terms applied to data infrastructure, where they can get overtaken by marketing hype unless we work to define them. In this talk, we’ll examine two different databases, TiDB and Apache Cassandra, in order to identify what it means for a database to be Kubernetes native and why it matters. We’ll look at points including: - The differences between cloud native, Kubernetes native, and serverless - How databases become Kubernetes native - Benefits of Kubernetes native databases - How Kubernetes can better support databases…

CRDs normally are kind of a byproduct of an operator. But in reality, they can be considered as the user-facing API of the operator surface. And as such, we would like to introduce conversations about even standardizing some of them, or creating "specifications" out of some CRDs. Take this for example: there are some CRDs that could be, potentially, common across multiple operators. Think of a CRD to represent an S3 (or any other storage object) bucket. For operators that store data in object stores, each and every one of them are creating their own versions. But shouldn't we have some "standardized" `ObjectStorage` CRD, without a controller, that all could use?

This talk will highlight challenges and best practices around centralized management of configuration, credentials, compliance across multiple accounts, regions, providers etc. We will also highlight the deviations in CSI driver implementations of various storage vendors and cloud providers. Finally, we will cover the various recovery options available in the market today. Kubernetes cloud services are popular since they mitigate, but do not eliminate, the difficulties of operating a Kubernetes environment. This is especially true for protecting the stateful configuration and data of your Kubernetes applications, where the inherent high-availability and infrastructure as code are not a substitute for have cloud-native backup and disaster recovery capabilities. Further, many companies now have multi-cloud strategies for their cloud-native applications. These challenges can be addressed with backup applications that are both Kubernetes managed service and multi-cloud aware in order to snapshot, copy, restore, and migrate Kubernetes workloads (resources and data) running on AKS, EKS and GKE. Capturing information from cloud accounts and how the cluster and storage resources are configured allows 1) centralized visibility into all cloud accounts and the clusters and resources in the accounts including for compliance; 2) cross-account, cross-cluster, and cross-region data restores; 3) automation of the cluster and data restores including for Dev, Test, and Production recovery use cases. BIO Sebastian Glab is a Cloud Architect for CloudCasa and he resides in Poland. He is responsible for integrating the different cloud providers with the CloudCasa service, and making sure that all clusters in the cloud service get discovered and protected.

הפעל מאוחר יותר הפעל מאוחר יותר רשימות לייק אהבתיhttps://go.dok.community/slack https://dok.community ABSTRACT OF THE TALK When providing data analysis as a service, one must tackle several problems. Data privacy and protection by design are crucial when working on sensitive data. Performance and scalability are fundamental for compute-intensive workloads, e.g. training Deep Neural Networks. User-friendly interfaces and fast prototyping tools are essential to allow domain experts to experiment with new techniques. Portability and reproducibility are necessary to assess the actual value of results. Kubernetes is the best platform to provide reliable, elastic, and maintainable services. However, Kubernetes alone is not enough to achieve large-scale multi-tenant reproducible data analysis. OOTB support for multi-tenancy is too rough, with only two levels of segregation (i.e. the single namespace or the entire cluster). Offloading computation to off-cluster resources is non-trivial and requires the user's manual configuration. Also, Jupyter Notebooks per se cannot provide much scalability (they execute locally and sequentially) and reproducibility (users can run cells in any order and any number of times). The Dossier platform allows system administrators to manage multi-tenant distributed Jupyter Notebooks at the cluster level in the Kubernetes way, i.e. through CRDs. Namespaces are aggregated in Tenants, and all security and accountability aspects are managed at that level. Each Notebook spawns into a user-dedicated namespace, subject to all Tenant-level constraints. Users can rely on provisioned resources, either in-cluster worker nodes or external resources like HPC facilities. Plus, they can plug their computing nodes in a BYOD fashion. Notebooks are interpreted as distributed workflows, where each cell is a task that one can offload to a different location in charge of its execution. BIO Iacopo Colonnelli is a Computer Science research fellow. He received his Ph.D. with honours in Modeling and Data Science at Università di Torino with a thesis on novel workflow models for heterogeneous distributed systems, and his master’s degree in Computer Engineering from Politecnico di Torino with a thesis on a high-performance parallel tracking algorithm for the ALICE experiment at CERN. His research focuses on both statistical and computational aspects of data analysis at large scale and on workflow modeling and management in heterogeneous distributed architectures. Dario is an SWE that turned DevOps, and he's regretting this choice day by day. Besides making memes on Twitter that gain more reactions than technical discussions, leading the development of Open Source projects at CLASTIX, an Open Source-based start-up focusing on Multi-Tenancy in Kubernetes. KEY TAKE-AWAYS FROM THE TALK From this talk, people will learn: - The different requirements of Data analysis as a service - How to configure for multi-tenancy at the cluster level with Capsule - How to write distributed workflows as Notebooks with Jupyter Workflows - How to combine all these aspects into a single platform: Dossier All the software presented in the talk is OpenSource, so attendees can directly play with them and include them in their experiments with no additional restrictions.…

Yes, inside, not outside Kubernetes. After all, a database should be seen as an application, a special type of application - for which it is legitimate to require an additional level of care and attention. However, the small price you pay for this is worth the return on investment that your organization receives by running microservice applications, plus database combos, inside your Cloud Native infrastructure. In this session, I will cover why it is important to make such a decision. Discover the challenges and the opportunities that running Postgres inside Kubernetes presents. I will discuss what we all expect from a good Postgres operator, including self-healing, high availability, scalability, backup and recovery, performance, and - last but not least - security.

הפעל מאוחר יותר הפעל מאוחר יותר רשימות לייק אהבתיhttps://go.dok.community/slack https://dok.community/ From the DoK Day EU 2022 ( https://youtu.be/Xi-h4XNd5tE ) Kubernetes is an emerging platform of choice for deploying and running PostgresSQL. Deploying 100 Postgres clusters is as easy as deploying one, and there is no need to tinker with tools like Ansible or Puppet. Resource sharing can be applied when it makes sense, allowing to run multiple Postgres databases in isolation on a single instance, each storing the data on a dedicated persistent volume. There are great open-source tools out there to deal with high-availability and backups than support or can be easily integrated into the Kubernetes workflow. Monitoring and alerting is easy to implement. People reported success in running Postgres on Kubernetes before. But there are also rough edges, like memory management or certain Postgres maintenance operations, such as installing extensions, that normally cause unnecessary database downtimes on Kubernetes. They are less of a problem for in-house deployments, but may become a deciding factor when running a managed service, competing with other such services running on bare-metal servers or virtual machines that are free of those issues. In this talk, I will share some of our learnings from running a managed PostgreSQL/TimescaleDB service on Kubernetes on AWS for a little more than a year: I’ll start with the motivation of running managed PostgreSQL on Kubernetes, the benefits and drawbacks. I’ll describe the architecture of the managed PostgreSQL cloud on Kubernetes I’ll zoom in on how we solved some of the Kubernetes-specific issues within our cloud, such as upgrading extensions without downtimes, taming the dreaded OOM killer, and doing regular maintenance and PostgreSQL major upgrades. I’ll share how open-source tools from the PostgreSQL ecosystem helps us to run the service and explain how we use them in a slightly non-trivial way. Oleksii has been working with PostgresSQL for almost 20 years, and has been deploying Postgres on Kubernetes since 2016, when his team at Zalando started the internal managed PostgreSQL service based on the in-house and open-source postgresql-operator. Around 2015, with some other team members, he stared working on a PostgreSQL HA project that later became Patroni. Long before that he was hacking PosgreSQL source code to implement binary replication on PostgreSQL 7.x, authoring some PostgreSQL extensions and contributing to the core PostgreSQL itself.

All systems fail sooner or later, whether it’s a regional e-commerce website or a major cloud region hosting thousands of applications. That’s why, instead of chasing these illusions, it’s worth focusing on the nines of availability. Based on true stories, this session walks you through modern data availability and reliability patterns used by architects whose applications withstood major cloud outages. With the focus on the data storage layer and Kubernetes, you’ll learn: * How to architect the data layer in Kubernetes with the server, zone, and region-level resiliency in mind. * How to find a compromise between latency and availability for multi-region deployments. * How to ensure the data layer remains reliable (i.e., always returns expected data) even during a major incident.

It allows us to potentially pay for only that which we use and can help drive down operational costs to the minimal amount of resources necessary. Architecting for serverless requires a unique look at app logic and the way it is deployed. It takes a combination of the logical and physical worlds. An architectural pattern has emerged where we can scale ephemeral compute separate from services that need to persist. We use Kubernetes to deliver exactly this. A “serverless” experience that is driven and enabled by compute pods and storage pods. We also have used our experience running thousands of database clusters on Kubernetes to automate the operational expertise of managing a distributed database.

1 The many uses of Kubernetes cross cluster migration of persistent data (DoK Day EU 2022) // Ryan Kaw 7:39
https://go.dok.community/slack https://dok.community/ From the DoK Day EU 2022 ( https://youtu.be/Xi-h4XNd5tE ) Multiple clusters exist in most Kubernetes environments today, and number of clusters will increase overtime. The reasons for having multiple Kubernetes clusters are many, for example, overcoming scale limits, reducing complexity, geo separation, redundancy and having separate production, staging, and development environments. Once you have multiple K8S clusters, it can be useful to have the ability to easily move or duplicate workloads across these different clusters. Kubernetes does not have a native method to allow migration or duplication of workloads across clusters. Fortunately, there are tools that provide this functionality. In this presentation we will explore the different uses cases for cross cluster migration, and what is involved, and how these migration tools work. We'll cover some popular uses cases, such as, Disaster Recovery, Test/Dev, and performance testing. Migration could entail moving the entire cluster, or individual workloads. The components that need to be moved would include configuration and resources stored in etcd, and persistent data residing on PVCs. We'll cover the uses cases and challenges for migration, and run through an example of using one of these migration tools.…

The Rap-God project uses Kubernetes orchestration for a stateful case which is an emerging topic, the Rap God project acts as a demonstration of how to use such features of Kubernetes. The project will be using Stateful sets that’d deploy Apache Cassandra (for its first cycle) and eventually it’ll be implementing the same API endpoints for various databases that will be with/on Kubernetes. We in the community intend to do this with PersistenceVolumes and Persistent Volume Claims. Keeping in mind the issues, various developers face, we also will be making options for storage classes. The project will allow the members to explore how they can customize the whole storage class setup according to their setup. The project will be bringing Helm, Cassandra, Kubernetes and Argo under its watch and shall actively expand on its implementation with the further iterations.

In this talk, we share the experience of running Kafka as a stateful Kubernetes workload in a cloud-native environment using the open-source Koperator and the tools we built to automate the whole lifecycle. While running a stateful service like Kafka on Kubernetes may be intimidating at the first glance, we share our thought process, the tools, and the results that can make this a reality in any organization. The Kubernetes Operator pattern helped us automate all the operational aspects for the lifecycle of the cluster; abstract away the cloud specifics allowing us to focus on Kafka; achieve increased resilience and elasticity; implement automated Kafka rebalancing using CruiseControl, and harness all the metrics to implement an observable environment. We also plan to demo how these all come together. Join us as we share our team's learnings on: - Considerations for running a stateful service in a multi-tenant Kubernetes cluster: - Pod sizing in terms of memory and CPU - Scheduling - Persistent Volume Claims (PVC) tuning - Resiliency topics - How to handle regular Ethos upgrades and maintenance - How to bring custom monitoring solutions - Advanced network topics such as using dedicated VIPs If you or your team ever wanted to learn how to run your own stateful service in Kubernetes and/or see what's possible, come join us!

https://go.dok.community/slack https://dok.community/ From the DoK Day EU 2022 ( https://youtu.be/Xi-h4XNd5tE ) Redis is a widely used open-source in-memory data store and cache that has become a key component in the development of scalable microservice systems. While all of the main cloud providers provide fully managed Redis services (Amazon ElastiCache, Azure Cache for Redis, and GCP Memorystore), it may also be simply implemented in Kubernetes if you require additional control over the Redis configurations. This session will lead you through setting up a Redis cluster on Kubernetes with data persistence. The lesson would concentrate on establishing a "prod"-ready Redis cluster that considers storage and persistence even after restarts and discusses recommended practices and considerations. With the help of monitoring and hardware optimizations for your cluster, you'll learn about measuring your performance and best practices for Redis on Kubernetes. We would conclude whether operators or Helm chart will be a more mature option for your Data on Kubernetes needs with Redis and a few tips as a production checklist.

Such volumes lose their data and the stateful applications lose their state. By the use of Persistent Volume TrashCan, users can get a grace period to undo such unintended delete operation. The deleted Persistent Volumes are staged for delayed deletes. They continue to live even after being deleted from k8 perspective, for a configurable time(retention period) and based on the system’s usage. The storage class of the PVC can dictate if they need to be staged for a delayed delete. StorageClass can also allow for configurable retention period. To recover a deleted PersistentVolume, users can create a new namespace with the same name and reapply the original PVC spec. The PVC will reference a special StorageClass to indicate that the new PersistentVolume needs to be restored from the TrashCan. This will allow the application to restart with the right state and data. This talk will showcase how to overcome one of the admin’s pain point seen in field involving accidental deletions of PVCs by using advanced storage management solutions in Kubernetes.

This contract is a set of gRPC services for provisioning, utilizing, and snapshotting storage volumes. In this talk, we will focus on one aspect of the CSI spec: Volume Snapshots. The talk will cover volume snapshots on Kubernetes CSI, with a deep dive on Kubernetes CSI snapshots. A short demo on the basics of the CSI snapshots on Kubernetes will help show how easy it is to start using CSI snapshots. After covering the basics on both container schedulers, we’ll deep dive into how backup systems can programmatically interact with the Kubernetes CSI snapshots client. This example will be based on Stork, an open-source backup system that has implemented the CSI spec. I believe this talk will be beneficial to the community because it covers some storage-related topics that have not been covered much in previous conferences. I’m hoping to bring the unique perspective of a Kubernetes CSI and Nomad CSI contributor, while also covering the CSI plugin maintainer and end-user perspective. With this wide audience, many conference attendees will be able to learn about stateful applications, CSI volume snapshots, and developing CSI drivers for any container scheduler. Grant Griffiths is a core contributor and reviewer for the Kubernetes CSI and SIG Storage communities working at Portworx.

There are countless operator implementations available, and new operators are being released on a daily basis. Organizations managing hundreds of Kubernetes clusters for dozens of developer teams are also challenged to manage the lifecycle of hundreds of Kubernetes operators. The goal is to keep the operational overhead to a minimum. In this talk, a closer look into the lifecycle of operators will be presented. With an understanding of how operators evolve, it becomes clear what challenges during operator upgrades. A brief overview of lifecycle management tools such as Helm, OLM, and Carvel is presented in this context. In particular, it will be discussed whether these tools can help, which restrictions apply and where further development would be desirable. At the end of this talk, you will know what operator lifecycle management is about, what its challenges are, and which tools may be used to reduce operational friction.

Interestingly, when combined with the right tools, these features can make Kubernetes very valuable for developers wanting to run massive production databases in development! This is exactly what was seen at "Extendi". The developers at Extendi deal with a large amount of data in their production Kubernetes clusters. But when developing locally, they didn't have an easy way of replicating this data. This replication was needed because it allowed developers to test new features instantaneously without worrying if they would work as expected when pushed to production. But replicating a 100Gb+ production database for development wasn't turning out to be an easy task! This is where leveraging Kubernetes + remote development environments came to the rescue. Running data on Kubernetes turned out to be way faster than any of the traditional approaches because of Kubernetes' ability to handle stateful workloads exceptionally well. And since Extendi already used Kubernetes in production - the setup process was fairly simple. This talk will cover practical steps on how leveraging Kubernetes based development environments allowed dev teams at Extendi to run production data on Kubernetes during development using features like Volume Snapshots, having a huge positive impact on developer productivity.

It has a rich ecosystem of different components. There are connectors for importing and exporting data, different stream processing libraries, schema registries and a lot more. This talk will show how to use it to read data from social networks such as Twitter, process them and use machine learning to analyze them. And all of it will be of course running on top of Kubernetes. Jakub works at Red Hat as Senior Principal Software Engineer. He has long-term experience with messaging and currently focuses mainly on Apache Kafka and its integration with Kubernetes. He is one of the maintainers of the Strimzi project which provides tooling for running Apache Kafka on Kubernetes.

https://go.dok.community/slack https://dok.community/ From the DoK Day EU 2022 ( https://youtu.be/Xi-h4XNd5tE ) What does Kubernetes provide that allows us to reduce the complexity of Apache Cassandra while making it better suited for cloud native deployments? That was the question we started with as we began a mission to bring Cassandra closer to Kubernetes and eliminate the redundancy. Many great open source databases have been adapted to run on Kubernetes, without relying on the deep ecosystem of projects that it takes to run in Kubernetes(there is a difference). This talk will discuss the design and implementation of the Astra Serverless Database which re-architected Apache Cassandra to run only on Kubernetes infrastructure. Built to be optimized for multi-tenancy and auto-scaling, we set out with a design goal to completely separate compute and storage. Decoupling different aspects of Cassandra into scaleable services and relying on the benefits of Kubernetes and it's ecosystem created a simpler more powerful database service than a stand alone, bare-metal Cassandra cluster. The entire system is now built on Apache Cassandra, Stargate, Etcd, Prometheus, and object-storage like Minio or Ceph. In this talk we will discuss the downstream changes coming to several open source projects based on the work we have done. Jake is a lead developer and software architect at DataStax with over 20 years of experience in the areas of distributed systems, finance, and manufacturing. He is a member of the Apache Foundation and is on the project committee of the Apache Cassandra, Arrow, and Thrift projects. Jake has a reputation for developing creative solutions to solve difficult problems and fostering a culture of trust and innovation. He believes the best software is built by small diverse teams who are encouraged to think freely.

1 Autoscaling Stateful Workloads in Kubernetes (DoK Day EU 2022) // Mohammad Fahim Abrar & Md. Kamol Hasan 10:14

הפעל מאוחר יותר הפעל מאוחר יותר רשימות לייק אהבתיhttps://go.dok.community/slack https://dok.community/ From the DoK Day EU 2022 (https://youtu.be/Xi-h4XNd5tE) Managing stateful workloads in a containerized environment has always been a concern. However, as Kubernetes developed, the whole community worked hard to bring stateful workloads to meet the needs of their enterprise users. As a result, Kubernetes introduced StatefulSets which supports stateful workloads since Kubernetes version 1.9. Users of Kubernetes now can use stateful applications like databases, AI workloads, and big data. Kubernetes support for stateful workloads comes in the form of StatefulSets. And as we all know, Kubernetes lets us automate many administration tasks along with provisioning and scaling. Rather than manually allocating resources, we can generate automated procedures that save time, it lets us respond faster when peaks in demand, and reduce costs by scaling this down when resources are not required. So, it’s really important to capture autoscaling in terms of stateful workloads in Kubernetes for better fault tolerance, high availability, and cost management. There are still a few challenges regarding Autoscaling Stateful Workloads in Kubernetes. They are related to horizontal/vertical scaling and automating the scaling process. In Horizontal Scaling when we are scaling up the workloads, we need to make sure that the infant workloads join the existing workloads in terms of collaboration, integration, load-sharing, etc. And make sure that no data is lost, also the ongoing tasks have to be completed/transferred/aborted while scaling down the workloads. If the workloads are in primary-standby architecture, we need to make sure that scale-up or scale-down happens on standby workloads first, so that the failovers are minimized. While scaling down some workloads, we also need to ensure that the targeted workloads are excluded from the voting to prevent quorum loss. Similarly, while scaling up some workloads, we need to ensure that new workloads join the voting. When new resources are required, we have to make the tradeoff between vertical scaling and horizontal scaling. And when it comes to Automation, we have to determine how to generate resource (CPU/memory) recommendations for the workloads. Also, when to trigger the autoscaling? Let’s say, a group of workloads may need to be autoscaled together. For example, In sharded databases, each shard is represented by one StatefulSet. But, all the shards are treated similarly by the database operator. Each shard may have its own recommendations. So, we have to find a way to scale them with the same recommendations. Also, we need to determine what happens when an autoscaling operation fails and what will happen to the future recommendations after the failure? There can be some workloads that may need a managed restart. For example, in a database, secondary nodes may need to be restarted before the primary. In this case, how to do a managed restart while autoscaling? Also, we need to figure out what happens when the workloads are going through maintenance? We will try to answer some of those questions throughout our session. ----- Fahim is a Software Engineer, working at AppsCode Inc.

From a 'distance' I saw a lot of potential where they already had knowledgable engineers but lacked the experience to get started as a company but also as individual engineers. I created a community at that client, filled with their engineers. It was open to everyone who wanted to learn and we saw everyone's input as equal. Because of that safe space the company now runs almost all their IT in the cloud in a way that made both the engineers and the managers happy. All simply by just being a nice guy! BIO Hi my name is Fabian Met and I have been working in the cloud native space for the past couple of years. I love to learn new tech and do so almost every day! When I learn something new I then always use that knowledge to teach people how tech that might seem difficult at first can actually be quite manageable! Making sure that people do not experience these huge hills they sometimes face trying to learn something new is what I love to do! My role as Techfluencer means that I will help companies and people alike to see the benefit and required investment to start innovating and using new technology. I don't do this as an authoritative figure, instead I love to talk to people and hear their stories and challenges. Listening to them and talking to them usually leads to insight for both parties and possible solutions that previously might not have seen feasible! KEY TAKE-AWAYS FROM THE TALK Even though you might not be in a position of power, I will show you that no matter who you are, be that a manager, engineer or even the janitor you can help make positive change in your company!…

But it's what we get with most database-as-a-service offerings in the public cloud. Kubernetes has the potential to change the game and let users run complex database anywhere they want. This talk tells the story of how we built a portable ClickHouse cloud service on Kubernetes. It runs on AWS and GCP, of course. Even better, we're working on managing databases in *any* Kubernetes cluster, even those behind firewalls and NAT gateways. We can pull it off because Kubernetes is truly portable. We'll share what we've learned about using Kubernetes portability create a new breed of managed database. We'll speculate about what this portends for the future of database management. BIO Robert Hodges has worked with over 20 different DBMS types starting with M204 back in 1983. His current favorite is ClickHouse, a popular open source data warehouse. He caught the Kubernetes bug at VMware in 2018 and has been working on it ever since. In his day job he runs Altinity, an enterprise software and services provider for ClickHouse data warehouses. KEY TAKE-AWAYS FROM THE TALK Kubernetes is a great data platform even for complex, stateful systems like data warehouses. This talk shows how Kubernetes' portability is not just a convenience. It is a powerful tool that allows users to locate data anywhere it's convenient but still have a SaaS user experience for administrators.…
