What comes after microservice?

(Jin Qing's Column, Oct. 25, 2021)

Reading "The Evolution of Distributed Systems on Kubernetes" from Bilgin Ibryam.

https://www.infoq.com/articles/distributed-systems-kubernetes/

What are the purpose of projects like Dapr, Istio, Knative? How can they change the world?

Modern distributed systems

The needs of distributed systems:

  • Business logic

  • Other

    • Lifecycle: deploy, rollback, upgrade, scale, stop, isolate, config
    • Network: connect, circuit break, retry, timeout, load balance, discover, security, trace
    • Resource binding: to API, protocol, message, data format
    • State: stateless, stateful, store

Monolithic architecture

enterprise service bus (ESB): not distributed

Cloud-native architecture

Kubernetes: Lifecycle

Service Mesh

Istio: Networking

Serverless

Knative: scale

Dapr

Networking, resource binding, state

  • Lifecycle: Kubernetes + operator
  • Networking: Envoy
  • Binding: Apache Camel
  • State: Cloudstate

Multi-runtime microservice

Write business logic as another runtime. Here runtime is a process?

What comes after microservice

Faas is not the best. Multi-runtime microservice maybe is.

Mecha architecture
