- Successful local business with tech debt problem
- Let's do microservices!
- "Yeah but I just don't think we're Netflix, you know?"

Mistake: Going Lone Wolf
Being a lone wolf is lonely...and can be dangerous
Bottom Line
You can't do this alone
How can you do avoid this mistake?
Be in the right team
If you aren't in one, try make one
If you can't make one try find one

- "We can give you the best, but the best takes time"
- 3 months: Look how clever we are
- 6 months: Hello world
- 18 months: 🚮

Mistake: Going Dark
https://tabsandspaces.io/atm-live-slides
https://tabsandspaces.io/atm-questions
No one wants to buy your perfect but functionally empty microservices framework
⚫
Mistake: Going Dark
Bottom Line
Sure study, Sure PoC, Sure as hell better build something!
How can you do avoid this mistake?
How does this get me closer to the dream?
Remember v2 is on it's way!

Start with big services to make it easier
Finish with big services later because it's hard
CQRS is basically all in one microservices, right?
Asynchronous Monolith...

Mistake: Building a "Halfway House"
https://tabsandspaces.io/atm-live-slides
https://tabsandspaces.io/atm-questions
When you don't build microservices today, you don't get microservices tomorrow
🏚
Mistake: Building a "Halfway House"
Bottom line
Start as you mean to go on
How can you do avoid this mistake?
Build the best microservices not something else
Use buzzwords to solve problems not just to use them

- Hand made CQRS silver bullets need to be fired out of custom CQRS guns
- Dev? You mean Dev-ops-QA-SRE-Data-UX engineers?

Mistake: Wearing all the capes at once

🦸♂️
Mistake: Wearing all the capes at once
Super heroes would look silly if they wore multiple capes!
Bottom line
To be as good as a specialist or a framework you need to be a specialist or a framework
How can you do avoid this mistake?
Caring about QA, Devops, Data, BA problems are each their own job, consider hiring for it
Frameworks, libraries, etc. should be chosen carefully but used liberally

- If we don't do async what is even the point?!
- We're out of time!!!
- Quick slap something together, hope this works 😬

Mistake: Building Rome starting with the palace
https://tabsandspaces.io/atm-live-slides
https://tabsandspaces.io/atm-questions
🏰
Mistake: Building Rome starting with the palace
9 out of 10 Romans prefer a well built town hall to a half built palace
Bottom line
Focus on delivering a horizontal rather than a vertical
How can you do avoid this mistake?
Make sure your first iteration solves a domain problem
Have an ideal solution and a realistic solution in mind
🧙
- DRY is the heckin' best!!
- > Be me: making my own patterns
- These new patterns are the heckin' best!!

"I said, empty your mind. Be formless, shapeless. Like water. You put water in a cup it becomes the cup...Be water my friend" - Bruce Lee
Bottom line
Your experience is awesome but new problems need new solutions
How can you do avoid this mistake?
Stay humble. Be skeptical that you've ever got it right
Technologies, practices, patterns; nothing should be sacred or safe from scrutiny

Failing at Microservices is easy
- Big Co has super-villain levels of resource
- Doesn't make things easier. Complexity doesn't go away it just moves

Don't forget
- Don't be a lone wolf, microservices are hard!
- Don't go dark, microservices, are hard!
- Don't build a halfway house, microservices are hard!
- Don't wear all the capes, microservices are hard!
- Don't start Rome with the palace, microservices are hard!
- Code wizard !== Microservices wizard, you're good, but microservices are hard!
