Today we are proud to announce Submariner, a new open-source project enabling network connectivity between Kubernetes clusters. We launched the project to provide network connectivity for microservices deployed in multiple Kubernetes clusters that need to communicate with each other.

How to Build Cloud Native CI/CD Pipelines on Kubernetes and Release Software Faster

Kubernetes is a powerful, open source, container orchestration/cluster management tool that helps you manage and deploy your containerized application and services on a cluster of machines. Operationalizing Kubernetes involves many different pieces, but a very important aspect is management of the containers and using Helm to build charts for your Kubernetes deployments.

Considerations When Designing Distributed Systems

Today’s applications are marvels of distributed systems development. Each function or service that makes up an application may be executing on a different system, based upon a different system architecture, that is housed in a different geographical location, and written in a different computer language.

Introducing Submariner: Multi-Cluster Networking for Kubernetes

As more organizations benefit from the increased availability and security offered by multi-cluster Kubernetes, the release of Submariner, a new open-source project sponsored by Rancher, now enables containers in different clusters to establish a direct network connection with each other.

Lambda Deployment Frameworks Compared

With AWS Lambda, deploying a new version of our application has never been simpler. However, we still need to take care of some underlying plumbing. Such as managing the configuration for our functions as well as other related resources such as API Gateway, CloudWatch log groups and IAM policies. Depending on the event sources you would like to use, you also need to provision the necessary EventSourceMapping in order to use Lambda with the likes of Kinesis Streams and SQS.
