Litmus is a toolset to do cloud-native chaos engineering. Litmus provides tools to orchestrate chaos on Kubernetes to help SREs find weaknesses in their deployments. SREs use Litmus to run chaos experiments initially in the staging environment and eventually in production to find bugs, vulnerabilities. Fixing the weaknesses leads to increased resilience of the system.
 
Chaos experiments are hosted on hub.litmuschaos.io. It is a central hub where the application developers or vendors share their chaos experiments so that their users can use them to increase the resilience of the applications in production.

Kubernetes has made it very easy to deploy applications to the cloud at a higher scale than ever, but the development practices have not evolved at the same speed as application deployment patterns. Today, most developers try to either run parts of the infrastructure locally, or just test these integrations directly in the cluster via CI jobs or the "docker build, docker push, kubectl apply" cycle. It works, but this workflow is painful and incredibly slow.

Resgate is a Go project implementing a realtime API gateway for the RES protocol with NATS server as messaging system. It is a simple server that lets you create REST, real time, and RPC APIs, where all your clients are synchronized seamlessly.
 
Resgate handles all API requests from your clients, instead of directly exposing your micro-services (represented by Node.js and Java below). Clients will connect to Resgate, using either HTTP or WebSocket, to make requests. These requests are sent to the micro-services over NATS server, and Resgate will keep track on which resource each client has requested. Whenever there is a change to the data, the responsible micro-service sends an event. Resgate will use this event to both update its own cache, and make sure each subscribing client is kept up-to-date.

 Hexagon is a microservices library written in Kotlin. Its purpose is to ease the building of services (Web applications, APIs or queue consumers) that run inside a cloud platform. It is meant to provide abstraction from underlying technologies to be able to change them with minimum impact. It is designed to fit in applications that conforms to the Hexagonal Architecture (also called Clean Architecture or Ports and Adapters Architecture).
