https://go.dok.community/slack https://dok.community/  From the DoK Day EU 2022 ( https://youtu.be/Xi-h4XNd5tE ) Postgres should run inside your Kubernetes cluster. 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...

https://go.dok.community/slack https://dok.community/  From the DoK Day EU 2022 ( https://youtu.be/Xi-h4XNd5tE ) Kubernetes SIG Storage is responsible for ensuring storage is available for containers in a pod when the pod is scheduled on a node.

https://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 mu...

https://go.dok.community/slack https://dok.community/  From the DoK Day EU 2022 ( https://youtu.be/Xi-h4XNd5tE ) “Zero downtime” and “always-on” are illusions. 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. B...

https://go.dok.community/slack https://dok.community/  From the DoK Day EU 2022 ( https://youtu.be/Xi-h4XNd5tE ) Serverless promises to change the way we consume software. 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...

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.
