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.

A Comparison of VMware and Docker

Servers are expensive. And in single-application installations, most servers spend the majority of their time waiting. Making the most of these expensive assets led to virtualization, and making the most of virtualization has led to multiple options for virtualizing applications. VMware and Docker offer competing methods for virtualizing applications. Both technologies work to make the most of limited hardware resources, but they do so in significantly different ways.
