2 COOLSTORE APPLICATION

3 COOLSTORE APPLICATION Online shop for selling products Web-based polyglot application using AngularJS Node Java with multiple frameworks (Spring, Java EE, etc) Microservices architecture Deployed using containers

6 MICROSERVICES ARCHITECTURE OVERVIEW

7 VALUES OF MICROSERVICES 7 FAST TIME TO MARKET EFFICIENCY SCALABILITY Small autonomous services can be developed and delivered faster Automating delivery and monitoring of small services is easier Fine grained scalability is easier and uses less resources

8 MICROSERVICES ARCHITECTURE Principles of microservices architecture: Model around Business Domain Culture of Automation (DevOps) Deploy Independently Scale Independently Release Independently Combined to form a system or application Antifragile - increased robustness and resilience under pressure Polyglot (language and framework independence) API / contract focused Decentralized data management CLIENT REST API SERVICE DATASTORE 8
