MONOLITHIC ARCHITECTURE

BENEFITS

• Easily understood

• Simple to develop

• Simplified debugging and testing

• Easy deployment


• One failed module kills all

• Difficult to scale

• Change is not easy

• Difficult to understand

• Single technology stack (pro and con)

• Agility impacted – unable to roll out

code fast

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

MICROSERVICE PRINCIPLES

• Developed independently

• Does one thing well

• Deployment Independence

• API Focused

• Decentralized Data Management

• Easy to scale

• Polyglot


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


MICROSERVICES + LINUX CONTAINERS

CONTAINER

Micro

Service

• Rapidly build, deploy, and run the services

• Technology agnostic

• Process Isolation out of the box

• Driving the entire industry towards

standards like the Open Container Initiative

(OCI)
