Microserviços + Contêineres = Kubernetes + Istio (Meetup PHP Microservices POA #6)

Palestra apresentada dia 29 de agosto de 2018 no Meetup #6 do PHP + Microservices apresentado na Kinghost em Porto Alegre. Abordamos a utilização de aplicações rodando como microserviços, mostramos o que é o Istio, instalamos ele em um cluster Kubernetes e mostramos algumas das suas funcionalidades em uma Demo.

  2. –Wikipedia “Microservice is a software development technique, a variant of

    the service- oriented architecture (SOA) architectural style that structures an application as a collection of loosely coupled services.”
  3. –Nginx “A service mesh is a configurable infrastructure layer for

    a microservices application. It makes communication between service instances flexible, reliable, and fast”
  4. Porque Istio? • Load balancing for HTTP, gRPC, WebSocket, and

    TCP traffic.
 • Fine-grained control of traffic behavior with rich routing rules, retries, failovers, and fault injection.
  5. Porque Istio? • Load balancing for HTTP, gRPC, WebSocket, and

    TCP traffic.
 • Fine-grained control of traffic behavior with rich routing rules, retries, failovers, and fault injection.
 • A pluggable policy layer and configuration API supporting access controls, rate limits and quotas.
  6. Porque Istio? • Automatic metrics, logs, and traces for all

    traffic within a cluster, including cluster ingress and egress.
  7. Porque Istio? • Automatic metrics, logs, and traces for all

    traffic within a cluster, including cluster ingress and egress.
 • Secure service-to-service communication in a cluster with strong identity-based authentication and authorization.
  8. Patterns • Necessário mudança nas aplicações • Tempo para construir

    as integrações com as libs • Limita as ferramentas que podem ser utilizadas na sua aplicação
  9. Patterns • Necessário mudança nas aplicações • Tempo para construir

    as integrações com as libs • Limita as ferramentas que podem ser utilizadas na sua aplicação • Difícil manter compatibilidade
