DoK Talks #68- The Kubernetes-native way to providing database services to developers // Adam Sandor
Bio… Adam is a Solutions Architect at Styra, helping companies adopt Cloud Native tech. Coming from a Java-dev background he is most excited about the space where software development and operations meet. When he is not flying in DCS World he is hacking on CI/CD, GitOps and Kubernetes Operators. Abstract of the talk… As Kubernetes is becoming the infrastructure platform of choice in many companies, database teams are struggling with the question whether to run databases on the cluster or outside of it. This talk will not answer that age-old question. I would rather focus everyone's attention to the developer experience. Modern CI/CD processes need development teams to be flexible and able to deliver without having to ask other teams for resources. So how can a database team provide reliable service while upping their game in DevEx? The answer in Kubernetes-land is providing Custom Resources backed by operators which handle database provisioning on or off the cluster in a way that fits into a GitOps CI/CD workflow. In this talk I will explain the concepts and dive into how you can make your own operator to provide a self-service interface for developers.

DoK #66 Crossplane Packages as a Distribution Mechanism // Daniel Mangum
Abstract of the talk… A typical user's journey with Crossplane starts with provisioning infrastructure using the Kubernetes API, then evolves to composing infrastructure into higher level abstractions, and culminates with building a complete platform using packages. Crossplane packages are distributed as OCI images, meaning that a platform API can easily be reproduced in any cluster, and they can declare dependencies, which specify the lower level services that support the higher level abstractions. This functionality allows for companies to distribute their product in an infrastructure provider-agnostic manner, and for infrastructure admins to build internal platforms made up of both generic and organization-specific components. Bio… Daniel Mangum is a senior software engineer at Upbound where he is a maintainer of Crossplane, an open source CNCF project. He has held leadership positions in the Kubernetes community, and is an active participant in multiple other open source efforts. When not working in the Cloud Native space, Daniel spends his time writing, speaking, and building tooling for the RISC-V ISA. Key take-aways from the talk… This talk will be useful for folks building an internal infrastructure platform, as well as folks that build a product that depends on some form of infrastructure (databases, caches, blob storage, etc.). We will cover how to both build and consume packages, paving the way for advanced usage of Crossplane.

DoK #51 Promscale: Using Prometheus + Promscale + PostgreSQL to go from Observation to Understanding // Matvey Arye
Abstract of the talk… Often when I talk about putting observability data into PostgreSQL people ask me: are you crazy? And yet this somewhat heretical view has the potential to unlock a lot of the power and promise of observability. Thanks to TimescaleDB (an extension to PostgreSQL), storing time series, metric data inside of a relational database is now efficient, fast, and scalable. This is thanks to its unique partitioning, compression, and horizontal-scalability features.  But even if this is possible to do, why would you? The answer to that lies in the power of a flexible data model, joins, and SQL (which Promscale supports in addition to PromQL). A flexible data model allows you to combine metric data with various other data - from machine information such as the number of cores, memory, etc. to location information using GPS coordinates. This allows you to enrich your metrics with supplemental information using joins and performing much more sophisticated analysis using SQL for capacity analysis, BI, and more.  A flexible data model brings us to our second heretical idea: combining multiple modalities of observation in a single database. Combining metrics, logs, traces, event data, etc. in one DB has two major advantages: the first being a similar analytical advantage to what is described above: the ability to join and cross-correlate various types of signals together. The second major advantage is operational simplicity. As we all know, databases are the hardest things in our infrastructure to maintain and operationalize because of that pesky thing called state. So why maintain multiple different types of database systems if you could maintain just one?  While these ideas about observability data on Kubernetes may seem unusual and counter-intuitive, I hope they will generate interest and start a good conversation. Bio… Mat has been working on data infrastructure in both academia and industry for the past decade. Currently, he is leading the Promscale team, to make it easy for people to store and analyze their Prometheus data in both PromQL and SQL. Previously, he completed his Ph.D. at Princeton and then worked as one of TimescaleDB's core architects where he concentrated on performance, scalability, and query power.

DoK Community #41 Designing Stateful Apps for the Cloud and Kubernetes // Evan Chan
Abstract of the talk… Almost all applications have some kind of state. Some data processing apps and databases have huge amounts of state. How do we navigate a cloud-based world of containers where stateless and functions-as-a-service is all the rage? As a long-time architect, designer, and developer of very stateful apps (databases and data processing apps), I’d like to take you on a journey through the modern cloud world and Kubernetes, offering helpful design patterns, considerations, tips, and where things are going. How is Kubernetes shaking up stateful app design?  - What kind of state is there, and what are some important characteristics? - Kubernetes, containers, and the stateless paradigm (pushing state into DBs) - Where state lives and the persistence characteristics - Stateless vs serverless - why stateless is not really stateless, but server less really is - Improving on stateless paradigm using local state pattern - Logs and event streaming for reasoning about state and failure recovery - The case for local disks: ML, Databases, etc. - Kubernetes and the Persistent Volume/StatefulSets - Leveraging Kubernetes PVs as a basis for building distributed data systems - Mapping the solution space Bio… Evan has been a distributed systems / data / software engineer for twenty years.

Dok en español #2 ¡Suelten el Krake! Trayendo la Energía al Lazo de Cómputo // Juan A. Fraire
Abstract of the talk… ENG: Cloud&Heat has always focused on providing energy-efficient data centers. In the last 8 years, we have developed an innovative water cooling technology for servers, converting waste heat into a valuable asset. By doing so, we have already greatly improved the energy efficiency of individual data centers. However, this isn’t enough. To globally maximize the efficiency of distributed data center infrastructures, this talk presents Krake. Krake is an orchestration software for compute-intensive jobs. It improves the global cost and energy efficiency of infrastructures by balancing the load between data centers. Krake evaluates and selects the most efficient site to run jobs based on certain metrics, such as energy availability, heat demand, and latency. It also reacts to changes in the system by migrating jobs. In other words, it ensures a job is run in the most energy- and/or cost-efficient way at any given time. ESP: Cloud & Heat siempre se ha centrado en proporcionar centros de datos energéticamente eficientes. En los últimos 8 años, hemos desarrollado una innovadora tecnología de refrigeración por agua para servidores, que convierte el calor residual en un activo valioso. Al hacerlo, ya hemos mejorado enormemente la eficiencia energética de los centros de datos individuales. Sin embargo, esto no es suficiente. Para maximizar globalmente la eficiencia de las infraestructuras de centros de datos distribuidos, en esta charla presentaremos Krake. Krake es un software de orquestación para trabajos intensivos en computación. Mejora el costo global y la eficiencia energética de las infraestructuras al equilibrar la carga entre los centros de datos. Krake evalúa y selecciona el sitio más eficiente para ejecutar trabajos según ciertas métricas, como la disponibilidad de energía, la demanda de calor y la latencia. También reacciona a los cambios en el sistema mediante la migración de trabajos. En otras palabras, asegura que un trabajo se ejecute de la manera más eficiente en términos de energía y costo en un momento dado. Bio… ES: Juan A.

#37 DoK Community: Running Data Replication Pipelines on Kubernetes with Argo // Stephen Bailey
Abstract of the talk… Hundreds of data teams have migrated to the ELT pattern in recent years, leveraging SaaS tools like Stitch or FiveTran to reliably load data into their infrastructure. These SaaS offerings are outstanding and can accelerate your time to production significantly. However, many teams prefer to roll their own tools. One solution in these cases is to deploy singer.io taps and targets — Python scripts that can perform data replication between arbitrary sources and destinations. The Singer specification is the foundation for the popular Stitch SaaS, and it is also leveraged by a number of independent consultants and data projects. Singer pipelines are highly modular. You can pipe any tap to any target to build a data pipeline that fits your needs, making them a good fit for containerized workflows. This article walks through the workflow at a high level and provides some example code to get up and running with some shared templates. I also drill into reasons for choosing the Argo approach over other orchestration tools like Airflow or Dagster, and the implications from a team perspective. Bio… Stephen Bailey is Director of Growth Analytics at Immuta, where he strives to implement privacy best practices while delivering business value from data. He loves to teach and learn, on just about any subject. He holds a PhD in educational cognitive neuroscience from Vanderbilt and enjoys reading philosophy

#18 DoK community: DoK Panel - The State of State // Rosemary Wang, Lili Cosic, Tomasz Cholewa & Jacquie Grindrod
Stateful vs stateless? We will stately be stating our statutes regarding the status of the state of statefulness and statelessness on k8s- oh yea! In the DoK Community, one of the main issues that folks have are how in the world can they flatten the learning curve when it comes to running stateful applications in k8s. That's why we've brought on 3 experts from 3 different countries to tell us what state state (intentionally doubled) is in! Rosemary Wang works to bridge the technical and cultural barriers between infrastructure engineers and application developers. She has a fascination for solving intractable problems with code, whether it be helping an infrastructure engineer learn to code or an application developer troubleshoot infrastructure failures. She also interfaces with vendors, clients, startups, and open source projects to find creative software solutions for infrastructure. When she is not drawing on whiteboards, Rosemary valiantly attempts to hack stacks of various infrastructure systems on her laptop while watering her houseplants. Lili Cosic is a Principal Software Engineer at Red Hat, working on OpenShift monitoring. She is also a kube-state-metrics, prometheus-operator and kube-prometheus project maintainer. Previously she worked at Weaveworks on the Weave cloud integration with Kubernetes and before that, she found her passion for Kubernetes operators at Kinvolk creating first operators. In her free time, Lili enjoys experimenting with Kubernetes, cooking and distributed systems. Tomasz Cholewa is the co-founder of Cloud Code Labs and he believes that good applications deserve even better environments where they can spread their wings and it's his job to help you create them. To achieve it he uses cloud and containers, but mostly he listens carefully to understand and use the right mix of proper technology and processes around it. His field of expertise is public cloud (AWS), containers and their orchestration engines - OpenShift and Kubernetes. Jacquie Grindrod is a developer advocate for HashiCorp with a focus on delivery and orchestration, where she’s able to apply her passion for solving problems with a holistic approach by bridging the gaps between teams and systems. In 2019, Jacquie was recognized as one of Canada’s Top 30 Under 30 Developers and has spoken at conferences including DevOpsDays Toronto and Grace Hopper Celebration.

#17 DoK community: Is k8s Even Ready For Data? Round II // Patrick McFadin & Jeffry Molanus
In our inaugural DOKC meet-up, Patrick McFadin Developer Advocate at Datastax emphasized the challenges of running Cassandra on Kubernetes, concluding at one point that “Kubernetes might not be ready for Cassandra.” Since that meeting, the use of the open-source Container Attached Storage project OpenEBS as a simple and high performance per workload storage for Cassandra has proliferated. Also the Cassandra Operator from Datastax, aka “CaSS”, has progressed as well. So - where are we now? Is CaSS on CAS working well? What is the future of collaboration between Datastax / Cassandra and MayaData / OpenEBS?  Is Kubernetes now ready for Cassandra?  What are the emerging technologies that might shape storage and Kubernetes in the near future? What are the reasons people avoid running DBs on Kubernetes? What makes it easier?

#15 DoK community: Reaching limits in K8s: A case study with Ingress Controller // Laurent Rouquette
When talking about data, we usually think about big data and scale, and what do we do next. Such limits are sometimes a good problem to have. In this talk, we'll discuss our approach to this situation using the Ingress Controller. Laurent is a Software Development Engineer at Adobe. He started in Dev, went to Ops (sometimes referred to as "SRE" these days), then became a manager and now he's back to being an individual contributor.  This is all on purpose: he likes to do new things! He grew up in Marseille, France (go Olympique de Marseille!), but moved to the US right after college and actually he's never had a real job in Europe... When he isn't coding, he likes playing soccer (although he's been doing a lot of "watching" since March 2020).

#13 DoK community: Distributed Workloads on Kubernetes Operators to the Rescue // Sebastien Guilloux
For our 13th installation of the data on k8s meetup, we will be talking with Senior Software Engineer Sebastien Guilloux from Elastic about Distributed workloads on k8s and how operators play a part in that! // Abstract: How easily can you run distributed workloads on Kubernetes? The initial deployment of your 10-nodes database might be easy to setup, but day-2 operations (changing the configuration, adding and removing nodes, version upgrades, etc.) are much more complicated. We'll discuss how operators can help you manage distributed workloads, and a few operator tricks we learned while working on ECK (Elastic Cloud on Kubernetes) - an operator for the Elastic stack. // Sebastien Guilloux Bio: Sebastien Guilloux is a senior software engineer at Elastic. He has spent most of his career working with distributed systems, building resilient applications, and orchestrating Apache Kafka and Elasticsearch nodes around the world.

#12 DoK community: PostgreSQL as a Service on K8s at Zalando // Alexander Kukushkin
// Abstract: PostgreSQL is a powerful, open-source object-relational database system with over 30 years of active development that has earned it a strong reputation for reliability, feature robustness, and performance, but a production-grade deployment requires many complementary technologies to the database core: high availability and automated failover, backup and recovery, monitoring and alerting, centralized access control and logging, connection pooling, and so on. Being not initially accustomed for running stateful workloads, Kubernetes with its infrastructure as a code paradigm, CustomResourceDefinition, and Operator pattern turned out to be extremely convenient for deploying and running PostgreSQL at scale.   I will talk about a few open-source project developed and maintained by database team at Zalando which anybody could use to build own PgaaS: 1. https://github.com/zalando/patroni - Tool for PostgreSQL high availability and cluster management. Integrates with K8s API and makes PostgreSQL cloud-native.   2. https://github.com/zalando/spilo - The Docker image that packages Patroni, multiple versions of PostgreSQL, and tools for backup and recovery.   3. https://github.com/zalando/postgres-operator - Implements Kubernetes operator pattern, orchestrates hundreds and thousands deployments of Patroni/Spilo clusters.   Aforementioned projects would never get to the current state without an effort of dozens of external contributors.   // Bio: During his professional career, Alexander touched PostgreSQL from all possible sides: as a Web Developer, as System Administrator, and as a Database Engineer now. Five years ago he started working on Patroni project and achieved quite a big success with it. Nowadays Patroni is used in the heart of PostgreSQL-as-a-Service on Kubernetes at Zalando to run 1000+ PostgreSQL HA clusters. Besides that, Alexander periodically reports bugs and contributes patches to PostgreSQL and some other open-source projects (usually Postgres related).   ▬▬▬▬▬▬ Show Notes ▬▬▬▬▬▬   Remember to put your toys away: https://twitter.com/braddwyer/status/1303751133765283840 Getting Write happy and burning out your SSDs https://blog.okmeter.io/real-world-ssd-wearout-a3396a35c663 GitLab Postmortem https://about.gitlab.com/blog/2017/02/10/postmortem-of-database-outage-of-january-31/   ▬▬▬▬▬▬ Connect with us 👋   ▬▬▬▬▬▬   Join our slack: https://go.dok.community/slack Follow us on Twitter: @dokcommunity Register for the next meetup: // Register here: https://go.dok.community/register Connect with Demetrios on LinkedIn: https://www.linkedin.com/in/dpbrinkm/ Connect with Alexander on Twitter: https://twitter.com/cyberdemn Connect with Bart on LinkedIn: https://www.linkedin.com/in/bart-farrell/ ▬▬▬▬▬▬  Supporters of the DoKc   ▬▬▬▬▬▬    This meetup is sponsored by MayaData, which helped start the DOK.community and remains an active supporter.

#10 DoK community: Data on Kubernetes and container attached storage - an update // Evan Powell
For our 10th installation of the data on k8s community meetup, we talk with CEO of Mayadata Evan Powell about container attached storage, Portworx acquisition, openEBS, can open source make it, and we geek out a bit with questions from the audience. // Key takeaways: Kubernetes - extended by CAS and other software - is not just solving the problems of running data on Kubernetes, it is fast becoming the preferred platform for data. // Abstract: Back in 2018 the CNCF published a blog we wrote called Container Attached Storage. Today - September 22nd 2020 - a new blog is appearing on their site updating Container Attached Storage. https://bit.ly/2FYGgeR  This talk borrows very heavily from that blog. What is CAS? Why would anyone use Kubernetes itself for storage? How does a microservices architecture help? Why is shared storage at the end of the road - though still used underneath CAS sometimes? // Evan Bio Evan has helped conceptualize, fund, position, lead and scale a few eventually important enterprise infrastructure software companies which were acquired. He is also a part time investor and mentor. Evan is currently CEO at MayaData. MayaData enables the use of Kubernetes as a data layer and sponsors open source projects including the CNCF project OpenEBS and the LitmusChaos engineering project. MayaData also helps to sponsor DOKC. Previously Evan helped conceptualize and build StackStorm, a DevOps workflow automation company, where he was co-founder and CEO.

#9 DoK community: Geospatial Sensor Networks and Partitioning Data // Alex Miłowski
For our 9th installation of the Dokc data on k8s meetup, we will be talking with Alex Milowski from Redis Labs. // Key takeaways: How are data collection and consumption workloads fundamentally different? What are the main challenges for sensor networks? How are those challenges address within the context of K8s? // Abstract: We use resources like weather reports or air quality measurements to navigate the world. These resources become especially important when faced by extreme events like the current wildfires in the Western USA. The data for the reports, predictions, and maps all start as realtime sensor networks. In this talk, Alex will present some of his research into scientific data representation on the Web and how the key mechanism is the partitioning, annotation, and naming of data representations. We’ll take a look at a few examples, including some recent work on air quality data relating to the current wildfires in the western USA. We’ll explore the central question of how geospatial sensor network data can be collected and consumed within K8s deployments. // Alex Bio Dr. Milowski is a researcher, developer, entrepreneur, mathematician, and computer scientist.

#8 DoK community: Appropriate workloads for databases in K8s // Rick Vasquez
For our 8th installation of the data on k8s meetup, we spoke with Rick Vasquez, Enablement Lead - Services Portfolio at Percona. // Key takeaways: Large unsharded data footprints are not great for kubernetes. Deploying databases in kubernetes is much different than just running an application in a container. Open source is playing catch up with regards to persistence and kubernetes. // Abstract: As more companies are moving to kubernetes and cloud native as a standard for developing net new functionality something has to happen to the legacy workloads. Often times we see a lift and shift mentality into kubernetes, we will talk about how that mentality can be dangerous or cause more work than expected. // Rick Bio: Hands-on technical practitioner with real world experience in some of the largest open source database deployments in the world.

#7 DoK community: Conway’s Law & Kubernetes: Centralization vs. small team autonomy // Joseph Sandoval & Mike Tougeron
Data on Kubernetes #7: Conway’s Law & Kubernetes - Centralization vs  small team autonomy with Mike Tougeron, Lead Site Reliability Engineer, at Adobe & Joseph Sandoval , SRE Manager, Platform Infrastructure, at Adobe. Loosely coupled teams, loosely coupled workloads and loosely coupled data - on a built for everyone platform? Abstract: Big clusters or small clusters?  Where to draw the line and how to know whats best for your use case? We speak with Joseph and Mike from Adobe about the inevitable questions that arise when running k8s at scale. If it is run by the platform team, is it inevitably a pet?  Or more of a pet?  Is that the idea, that we give stuff that ” must not fail” to platform teams so they are common services w/ SLAs?  Or how is it decided what is owned by the platform vs. the individual teams. While talking with Joseph and Mike we also dive into what their stack looks like, must have tools they use on a daily bases, VM vs K8s, differences in stateful apps on k8s and War stories! Mike T Bio: For many years Mike has been building Kubernetes platforms and deployments. With a passion for automation and developer engagement, Mike works towards continuously improving development pipelines to take the complication out of managing services on large-scale infrastructure backed by both vm and containers across multi-cloud environments. Mike is a lazy programmer who would rather write thousands of lines of code for automation instead of running repetitive commands every day. When not coding or playing with his son you’ll find Mike with his nose buried in a book or playing Civilization.

#4 DoK community: The problem of stateful workloads - balance of keeping data HA vs. costs // Ren Lee
Balancing redundancy and HA with costs: did you really need all N replicas?AKA We were running what and it cost us how much?! With Ren Lee SRE at Arista Networks Key takeaways: “Lazy but Simple” vs. “Proactive but Expensive” methods of scaling: knowing when to pay the seemingly scarier price of running infrastructure than costing engineering time, and vice versa Hidden costs: cost of bad deployments and things that just don’t work When autoscaling becomes the demon: especially in public cloud environments when access to pools of resources is no longer your barrier Abstract: In an engineer’s ideal world we would love all the resources and redundancies we can possibly get for our services and infrastructure that supports them for sanity and of course, HA. However, how do you balance between “enough” redundancy and the actual operational costs of supporting such engineering choices, and what are some of the tough engineering decisions that need to be made? This talk focuses primarily on services being run on Kubernetes (or public cloud offering of Kubernetes), but the principles can be extended to any infrastructure environment. Key Topics: capacity planning, cost management, distributed services Bio: Ren is an SRE at Arista Networks for CloudVision services team. Deeply passionate about fixing broken things without anyone noticing and using effective monitoring to preempt potential disasters. Wrangler of services that run on Kubernetes to keep the zoo running any day, every day.

#2 DoK community: Data on k8s maturity check // Zach Dunn
Data on Kubernetes community virtual meetup #2 with Zach Dunn Senior Direct of Platform Operations, Optoro. We talk today about how the team at Optoro has implemented stateful apps on Kubernetes and what they have learned along the way.   Let’s talk about storage. Optoro has moved to running stateful stores on Kubernetes. It’s a challenge, but it has a lot of value. Let’s talk about how we chose to do it, and what we figured out along the way.  Key takeaways: Learn about how Optoro chose to run stateful services on kubernetes. Laugh at other people's mistakes! Cry with us over our pain. Maybe question some of the assumptions around storage in k8s. Wonder about the future of data in Kubernetes.   Bio: Zach's spent most of his tech career in something that vaguely resembles production infrastructure. This has ranged from hot aisle drudgery to professional nerd herder and budget owner. Once an individual but now is he collectively just known as "Arabella's Dad" or on occasion "William's Dad". He currently is the Senior Director of Platform Operations and CISO at Optoro helping teams build and deliver modern software for enterprise clients   Join our slack: https://join.slack.com/t/dokcommunity/shared_invite/zt-g3ui5r0g-jDKz5dhh2W1ayElqwKYYAg Follow us on Twitter: @dokcommunity   Connect with Demetrios on LinkedIn: https://www.linkedin.com/in/dpbrinkm/ Connect with Zach on Linkedin: https://www.linkedin.com/in/zach-dunn-11507217/   This meetup is sponsored by MayaData, which helped start the DOK.community and remains an active supporter.

#1 DoK community: Is k8s even ready for data? // Patrick McFadin
Our kick-off inaugural event of Data on Kuberneters commenced with VP Developer Relations of Datastax Patrick McFadin talking about this vision for the future of doing data on k8s   Kubernetes has been a great solution for deploying application infrastructure. Trying to manage your data with the same control plane has been, less than ideal. This has been even more true when using distributed databases like Apache Cassandra. Once you get past the storage and stateful sets, you still have a lot to do. Let’s have a frank talk about the new opportunities to make Kubernetes ready for data.   Patrick McFadin is the VP of Developer Relations at DataStax, where he leads a team devoted to making users of Apache Cassandra successful. He has also worked as Chief Evangelist for Apache Cassandra and consultant for DataStax, where he helped build some of the largest and exciting deployments in production. Patrick is active in the Apache Cassandra project and a member of the CNCF TOC.   The new data on k8s community (DOKC) is an openly governed and self-organizing group of curious and experienced operators and engineers concerned with running data-intensive workloads on Kubernetes. We will have weekly meetups on Tuesdays at 5pm UK / 9am PST and everything will be recorded and put up on youtube and podcast land.    I am currently looking for speakers who can talk about things such as operators, databases, multicloud/hybrid, or anything else that could be interesting for the SRE engineering crowd.   Join our slack: https://join.slack.com/t/dokcommunity/shared_invite/zt-g3ui5r0g-jDKz5dhh2W1ayElqwKYYAg Follow us on Twitter: @dokcommunity   Connect with Demetrios on LinkedIn: https://www.linkedin.com/in/dpbrinkm/ Connect with Patrick on Linkedin: https://www.linkedin.com/in/patrick-mcfadin-53a8046/   This meetup is sponsored by MayaData, which helped start the DOK.community and remains an active supporter.
