3 WHAT ABOUT ME? • Developer for 7+ years •
@ Posedio since 2022 • Sagittarius with Virgo rising • Cat Lover • Informatics as a craft not a science Philipp Seifert-Kehrer
ROADMAP 1. Xs and Os 2. Where Promised Land? 3.
It’s Tricky getting it right 4.The Majestic Monolith 5. Pretty sus Standard
MICROSERVICES – MONOLITHS XS AND OS 1
6 HOW COME I GATHERED YOU HERE TODAY
7 MICROSERVICES? MONOLITHS? Many small applications Do 1 thing well
Communication via HTTP Teams own specific services Wut? One deployable
8 ADVERTISED BENEFITS Easier to build and maintain Improved productivity
and speed Flexibility in technologies Autonomous teams Improved Scalability and Fault Isolation
9 SO, WHAT TO EXPECT FROM THIS TALK? Questioning microservices
as standard architectural approach in modern applications AND Arguing for monoliths as a solid architectural choice in modern applications
2
11 RESPONSIBILITY PING PONG
12 PIPE DREAM OF FASTER DEVELOPMENT
13 INDEPENDENCE We can change implementation without coordinating with others
14 MICRO… IS PRETTY DAMN SMALL Starting off too small
Frontend glue How small is too small?
15 AMPLIFIED PROBLEMS Increased Load/Latency Fault Isolation only technically More
possible sources of error
16
IT’S TRICKY 3
18 EVERYONE CAN BE A DEVELOPER
19 DISTRIBUTED SYSTEM
20 GAMEPLAN Single team or outstanding communication Profound knowledge of
domain Clear-cut understanding of non-functional requirements Developers that are skilled and accountable
21 BUT… … unless you really really really have to!!!
22
THE MAJESTIC MONOLITH 4
24 LEGACY UP YOURS
25 MONOLITHS ARE NOT PERFECT, BUT… Easy to refactor
26 WHAT YOU WANT What you really really want
27 SEPARATION OF CONCERNS https://github.com/spring-projects/spring-modulith
28 THAT FANCY SPRING PROJECT
A PRETTY STANDARD 5
30 GETTING IT RIGHT FROM THE GET GO
31 ADMIT YOU DON’T KNOW SHIT… … at the beginning
of a project/startup/whatever… … but are willing to learn and adapt accordingly.
32 DON’T BE THAT GUY/GAL
33 WHO BENEFITS MOST FROM MICROSERVICE HYPE?
34 NICE CONCEPT Reality hits different Solution for very specific
problems New problems to solve
35 BEST PART ABOUT MICROSERVICES? They tend to be easily
refactored into a monolith.
36 WRAPPING IT UP Maintainability Availability Scalability Sustainability Get away
from microservices as a standard Stop trying to outsmart the world Start off with a monolith Adapt according to the problems at hand Go big or go home
37 “So, don’t be a prick Admit you don’t know
shit And start off any project with some nice monolith” - Drake
