  • 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.

  • Polyglot Microservices Communication Using Dapr on AKS

    Dapr is a useful tool for solving several challenges engineers might face. It allows engineering organizations to gain productivity by training developers on a common set of tools and techniques. It also helps adopt standardization in development, deployment, and debugging.

  • 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.

  • Choosing the Right Cloud Infrastructure for Your SaaS Start-up

    As a solutions architect, I have been designing SaaS applications for years and I have seen start-ups struggle to find the right cloud infrastructure and improve their product offering. These experiences prompted me to write this article as a tool to help companies make a pragmatic fact and data-driven decision.

  • What Does Zero Trust Mean for Kubernetes?

    Zero trust is a powerful security model that’s at the forefront of modern security practices. It’s also a term that is prone to buzz and hype, making it hard to cut through the noise. So what is zero trust, exactly, and for Kubernetes, what does it mean in concrete terms? In this article, we’ll explore what zero trust is from an engineering perspective.

  • 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.

  • Discovering the Versatility of OpenEBS

    OpenEBS provides storage for stateful applications running on Kubernetes, including dynamic local persistent volumes or replicated volumes using various "data engines". OpenEBS can address a wide range of applications, from casual testing and experimentation to high-performance production workloads

  • Embracing Cloud-Native for Apache DolphinScheduler with Kubernetes: a Case Study

    This article shares how Apache DolphinScheduler was updated to use a more modern, cloud-native architecture. This includes moving to Kubernetes and integrating with Argo CD and Prometheus. This improves substantially the user experience of deploying, operating, and monitoring DolphinScheduler.

  • Reduce Carbon Dioxide Emissions with Serverless and Kubernetes Native Java

    Moving application workloads to multi- and hybrid cloud platforms causes more carbon dioxide emissions, although better scalability and performance. Serverless and Kubernetes Native Java enable developers to solve the global climate changes by reducing carbon dioxide emissions by natively native features with milliseconds first boot time, tiny resident set size memory and scalability.

  • Article Series: Native Compilation Boosts Java

    Java dominates enterprise applications. But in the cloud, Java is more expensive than some competitors. Native compilation makes Java in the cloud cheaper. It raises many questions for all Java users: How does native Java change development? When should we switch to native Java? When should we not? And what framework should we use for native Java? This series provides answers to these questions.

  • Kubernetes Native Java with Quarkus

    Quarkus is an industry leader in startup time and memory utilization for native and JVM-based Java applications. This reduces cloud costs. Kubernetes is a first-class deployment platform in Quarkus with support for its primitives and features. Developers can use their Java knowledge of APIs like Jakarta EE, MicroProfile, Spring, etc. Applications can be imperative or reactive - or both!
