Inspired by Michael Cades' #90DaysOfDevOps and his ask for me to participate in his 2023 iteration to discuss 7 Days of Service Mesh, I decided to create a #70DaysOfServiceMesh.
70 Days of Service Mesh allows me to dig into plenty of areas to help myself (and others) better understand the inner workings of a service mesh. Some days will be a bit of a mini blogpost while other days might be very tutorial oriented.
Also, these are 70 sequential days of service mesh. It means I'll spend about day focusing on one topic. Hopefully I wrap this up within 90 days because 2023 is starting to look BUSY.
In this repo, we'll dig into a structured and iterative approach to learning Service Mesh.
- What is a Service Mesh
- Comparison of Service Meshes
- Networking Recap
- Kubernetes Recap
- Envoy
- Traffic Engineering
- Application Resiliency
- Observability
- Security and AuthN/AuthZ
- Istio Ambient Mesh
- Expanded areas of Istio
The table below outlines what we'll cover in 70 Days of Service Mesh, with Istio being the main focus.
Note Some of this is subject to change.
