Software enablers
As we've already mentioned, we have a number of very good open source tools that can help us both meet our expectations of microservices and, most importantly, handle the new challenges that come with them:
- Spring Boot, an application framework
- Spring Cloud/Netflix OSS, a mix of application framework and ready-to-use services
- Docker, a tool for running containers on a single server
- Kubernetes, a container orchestrator that manages a cluster of servers that run containers
- Istio, a service mesh implementation
The following table maps the design patterns we will need to handle these challenges, along with the corresponding open source tool that will be used in this book to implement the design patterns:
| Design Pattern | Spring Boot | Spring Cloud | Kubernetes | Istio |
| Service discovery | Netflix Eureka and Spring Cloud LoadBalancer | Kubernetes kube-proxy and service resources |
||
| Edge server | Spring Cloud Gateway and Spring Security OAuth | Kubernetes Ingress controller | Istio... |
