This document discusses microservices and provides an overview of the topic in 5 sections. It begins by defining microservices and their characteristics. Next, it compares monolithic architectures to microservices, noting that microservices allow for greater scalability, flexibility and easier deployment compared to monolithic applications. The document then covers some of the challenges of implementing microservices before discussing when and where they should be considered for an application. It recommends microservices when applications need flexibility, cost-effectiveness and scalability. It also suggests deploying microservices in the cloud.

application is
like a house:

you can’t

10. Monolithic vs. Microservices
10
Code
Clarity
Deployment
Language
Scaling

11. Monolithic
single code base for the entire
application
Microservice
Multiple code bases; each
microservice has its own
Monolithic vs. Microservice

Code

12. Monolithic
Can be confusing; hard to
maintain
Microservice
Better readability; easier to
maintain
Monolithic vs. Microservice

Clarity

13. Monolithic
Maintenance windows,
scheduled downtimes
Microservice
Simple; deployed individually,
no downtime

Deployment

14. Monolithic
Typically developed in
one language
Microservice
Services can be written in
different languages

15. Monolithic
Scale entire application
Microservice
Scale individual services, not
entire applications
