Scaling a Distributed Stream Processor in a Containerized Environment

The article presents our experience of scaling a distributed stream processor in Kubernetes. The stream processor should provide support for maintaining the optimal level of parallelism. However, adding more resources incurs additional cost and also it does not guarantee performance improvements. Instead, the stream processor should identify the level of resource requirement and scale accordingly.

Getting Started with Istio Service Mesh Routing

In the following tutorial, we will use Istio to demonstrate one of the most powerful features of service meshes: “per request routing.” This feature allows the routing of arbitrary requests that are marked by selected HTTP headers to specific targets, which is possible only with a (OSI) layer 7 proxy. No layer 4 load balancer or proxy can achieve this functionality.

Stateful Service Design Considerations for the Kubernetes Stack

At this summer’s QCon in New York, Jonas Bonér delivered one of the most popular talks of the conference with his focus on Designing Events-First Microservices. In this InfoQ Q&A, we asked Bonér to explain how “bringing bad habits from monolithic design” is a road to nowhere for service design, and where he sees his Akka framework fitting in the cloud-native stack.

Who Is Running My Kubernetes Pod? The Past, Present, and Future of Container Runtimes

Container runtime choices have grown over time to include other options beyond the popular Docker engine. The Open Container Initiative (OCI) has successfully standardized the concept of a container and container image in order to guarantee interoperability between runtimes. This article looks at the past, present, and future of container engine implementations.

Microservices in a Post-Kubernetes Era

How are microservices standing in the Kubernetes era? The microservice architecture is still the most popular architectural style for distributed systems. But Kubernetes and the cloud-native movement have redefined certain aspects of application design and development at scale.

Improving Testability of Java Microservices with Container Orchestration and a Service Mesh

In enterprise test scenarios, software needs to be tested in the same way as it will run in production. This article provides a practical demonstration of testing Java microservices that are running on Kubernetes with the Istio service mesh. K8s service abstractions enable mocking, and Istio enables us to re-route traffic and inject faulty responses or delays to verify our services' resiliency.

Packaging Applications for Docker and Kubernetes: Metaparticle vs Pulumi vs Ballerina

Metaparticle, Ballerina, and Pulumi have introduced different approaches by empowering developers to handle deployment automation within programing language itself without having handwriting YAMLs. This is becoming a trend and will change the DevOps practice in the software industry.

Building an API Gateway with the Ballerina Programming Language

An API Gateway is a layer in an architecture pattern that allows the business API to focus on the business functionality while taking care of the request dispatching, policy enforcement, protocol translations and analytics. This article is about how we built an API Gateway in Ballerina for the WSO2 API Manager.
