This document discusses modernizing enterprise application architecture with microservices and API management. It describes how a traditional monolithic architecture can be challenging to scale and change. A microservices architecture addresses these challenges by developing applications as suites of independently deployable services. The document outlines principles of microservices and how technologies like containers, Kubernetes, OpenShift, and API management can help implement microservices. It provides examples of how JBoss products like EAP, Fuse, and others can be used to build microservices.

MONOLITHIC ARCHITECTURE
CHALLENGES

SOLUTION: MICROSERVICE
ARCHITECTURE
“... 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.”
Martin Fowler

TRANSITIONING TO A MICROSERVICES
ARCHITECTURE
Don't even consider microservices unless you have a system that's too complex to manage as
a monolith - Martin Fowler
