Mám radši, když se mě někdo zeptá na něco konkrétního a ja to můžu zkusit nějak zodpovědet . S delší diskuzí, protože to je takový multipravdový téma.

Tomáš Strejček - Velikost týmu vs. monolith a mikroservicy (11. sraz přátel PHP v Praze)
- 1. monolith vs microservices vs team Tomáš Strejček, Dev Leader, Mall Group @TomasStrejcek
- 3. No PHP, #bummer But we can chat about it later and I will mention few things about what we do and how. But I must say, lot of things are pretty generic, no matter the programming language.
- 4. Don’t take me too seriously No, really. Don’t.
- 6. I will not tell you what is better ..but I will show you stuff that matters
- 7. I won’t show you how to do M/SOA ..you can google that sh**
- 9. Monoliths are big and strong ..and maybe bloated. But what does it mean? How does it look like?
- 11. Big ball of mud ..is something you don’t want. Ever.
- 16. Monoliths or microservices, it may still end up in the same hell hole Or not, but you really have to design your application first hand.
- 17. All the musts for M/SOA are valid for every software project Documenting! Testing! Loose coupling! No shortcuts! No hacking! Good SW design! Separation of concerns! Fast deployments! Continuous integration! Monitoring! Caching! Other stuff!
- 18. Is it really binary (or black and white for nontech) problem? It is not.
- 21. How hard is to find what is going on? Are monitoring tools and logs enough? Do you have API?
- 22. Microservices are great, but you need to GET there, not START there.
- 23. #MonolithFirst Is then M/SOA last?
- 24. Monolith -> ? -> M/SOA ? = time or something else
- 25. Modular distributed monolith architecture MDMA for short I made it up obviously but it really made me laugh, so I am rolling with it.
- 27. What I mean is.. ..wait for it ..
- 28. Is application different when run in CLI instead over FPM? It should be.
- 29. Is application different when you access it through user backend or user frontend? It should be.
- 30. You, as developers, have great power to change you app behavior via configuration. Incl. feature flags, environment variables etc.
- 31. How do you maintain 20 microservices in team of 5 developers? You can’t and you shouldn’t get to the point where you do.
- 32. Managing, deploying and scaling complexity is hard. But deploying single app? Just git pull and adios.
- 33. Everybody doesn’t have to be DevOps Not even those fancy react redux nodejs javascript hybrid guys rolling on AWS.
- 34. Infrastructure as a code to the rescue! Or not, you don’t really need IaaC in monoliths.
- 35. What really matters: does it work? :) (for you)
- 36. Thank you! Questions? Tomáš Strejček, Dev Leader, Mall Group @TomasStrejcek
