Containers and Serverless—Rivals or Cohorts?

This article will try to decode these technologies and explore how developers should consider containers or serverless functions within their tech stack. For example, if your application has a longer startup time, then a container would suit the need better. Highly efficient stateless functions that need to scale up and down massively would benefit from running serverless functions.

Securing a Kafka Cluster in Kubernetes Using Strimzi

Deploying an Apache Kafka cluster to Kubernetes is easy if you use Strimzi, but that’s only the first step; you need to secure the communication between Kafka and the consumers and producers, provide RBAC to access topics, spread the secrets correctly to Kafka Connect components and all using a Kubernetes GitOps way.

Create Your Distributed Database on Kubernetes with Existing Monolithic Databases

The next challenge for databases is to run them on Kubernetes to become cloud neutral. However, they are more difficult to manage than the application layer, since Kubernetes is designed for stateless applications. Apache ShardingSphere is the ecosystem to transform any database into a distributed database system and enhance it with sharding, elastic scaling, encryption features, and more.

Why Observability Is the Key to Unlocking GitOps

In a GitOps work process, Git is the single source of truth for the system’s intended state. Observability can provide the missing piece: the single source of truth for the system’s actual state.

Moving Kafka and Debezium to Kubernetes Using Strimzi - the GitOps Way

Deploying an Apache Kafka cluster to a Kubernetes is not an easy task. There are a lot of pieces to configure like the zookeeper, the Kafka cluster, topics, and users. Strimzi is a Kubernetes controller making the deployment process of Kafka a child game. Moreover, Strimzi lets you manage Kafka using GitOps methodology as everything is executed using a Kubernetes YAML file.

Managing Kubernetes Secrets with the External Secrets Operator

Kubernetes doesn’t yet have the capabilities to manage the lifecycle of secrets, so sometimes we need external systems to manage this sensitive information. Once the amount of secret information we need to manage increases, we may need additional tools to simplify and better manage the process. In this article, we’ll take a detailed look at one of these tools, the External Secrets Operator.
