Abstract of the talk… Kubernetes became the standard for micro services architectures. But what about handling massive and scalable data management on top of it? Is it possible and what does it mean for operations? Cassandra has been adopted widely and accepted globally as the most scalable and reliable database. Now it adds ease of use by offering a Kubernetes native plug and play solution for enterprise use! Bios… Michel has been specializing in NoSQL technologies and Distributed Data Manageme...

https://go.dok.community/slack Abstract of the talk… Even though microservices are becoming a pattern, we still see a lot of "monolithical" deploys and manual reactive actions. This blocks the ability to achieve maximum velocity in your release. We can leverage data and smart use of traffic-shaping to achieve a higher release velocity AND quality. Bio… Olaf has over 20 years of experience in the internet industry in technical, architectural and IT management roles. With a background as a softwar...

In this talk, I would like to uncover our newly announced Vitess Operator for Kubernetes. This talk demonstrates the sample implementation of Vitess in Kubernetes topology. I also explore common DBA tasks by demonstrating how they are handled in the Vitess ecosystem. Vitess, out of the box, comes with a lot of tools and utilities that one has to either incorporate or develop to manage MySQL topology. Let’s take a look at the capabilities of Vitess in these areas and demonstrate how they are perf...

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...

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 CaS...
