Yohanes Widi Sono - Modern Development for Business Agility
1 like•120 views
The document discusses modern approaches to application development for business agility, including microservices architecture and DevOps practices. It summarizes that high-performing organizations deploy code 200x more frequently, have 3x lower failure rates, and recover from failures 24x faster. The document then provides an overview of microservices architecture, challenges with monolithic applications, and how Red Hat technologies can help organizations adopt modern app development practices for the hybrid cloud.

- 8. ARCHITECTURE
- 9. “In short, the microservice architectural style is an approach to developing a single application as a suite of small services, each running in its own process and communicating with lightweight mechanisms, often an HTTP resource API. These services are built around business capabilities and independently deployable by fully automated deployment machinery. There is a bare minimum of centralized management of these services, which may be written in different programming languages and use different data storage technologies.” WHAT IS A MICROSERVICE? - James Lewis and Martin Fowler
- 10. HOW SMALL IS A MICROSERVICE? ● Small as in “single responsibility” ● Each service only does one thing, and one thing well ● Not about lines of code, but “small enough to fit in your head” ● Maybe even small enough that you can throw them away – Rewrite over Maintain µSVCµSVCµSVC µSVC SVC µSVC SVC µSVC µSVC

Patches to your application as well as your “stack” are also deployments. Your stack consisting of the OS, JVM, runtime engine (e.g. Tomcat, Vert.x, JBoss EAP), frameworks (e.g. Spring) all should be regularly patched via your CD Pipeline
