fabric8 vs Istio: What are the differences?
fabric8: Open source microservices platform based on Docker, Kubernetes and Jenkins. fabric8 makes it easy to create microservices, build, test and deploy them via Continuous Delivery pipelines then run and manage them with Continuous Improvement and ChatOps; Istio: Open platform to connect, manage, and secure microservices, by Google, IBM, and Lyft. Istio is an open platform for providing a uniform way to integrate microservices, manage traffic flow across microservices, enforce policies and aggregate telemetry data. Istio's control plane provides an abstraction layer over the underlying cluster management platform, such as Kubernetes, Mesos, etc.
fabric8 and Istio belong to "Microservices Tools" category of the tech stack.
fabric8 and Istio are both open source tools. It seems that Istio with 18.5K GitHub stars and 3.1K forks on GitHub has more adoption than fabric8 with 1.75K GitHub stars and 531 GitHub forks.
