SpringOne Platform 2016 Speaker: Alois Reitbauer; Chief Technology Strategist, Dynatrace The cloud has transformed the way we build applications. Early adopters prove that the benefits manifest in delivering value faster to the customer, less operational costs and more productive teams. The interesting question is how to get there, especially if you cannot simply start over and get your current applications benched. Through numerous customer engagements we have learned that there is a pattern followed by companies that do this successfully. This talk show you: -How to deploy faster without breaking things -Start decoupling a monolith without breaking your business logic. -Help developers build application using a new paradigm -Dynamically scale your applications to save costs -Manage highly dynamic larger-scale micro services without increasing operational costs As we will walk through the journey we share learning covering challenges and possible solutions on the organizational, development and operational side. As a company that has gone through this transformation itself while onboarding over 500 new customers we have some interesting stories to share.

1. Journey to Cloud Native
How to move to the cloud in three steps

3. Bimodal IT
Not every project is a cloud project, but cloud thinking is everywhere

4. Develop
Big monolithic application. Small interconnected purpose-built services.

5. Pizza Box Teams
Small teams can deliver features into production

6. New Rules in the Game
You build it, you run it.
Werner Vogels, CTO Amazon

7. Ship
Deploy
Big Bang Releases of single special built applications. Small continuous service delivery of standardized delivery blocks.

8. Compute
Hardwired datacenters. Datacenter as an API.

9. The journey to become cloud-native
We see three different stages how
companies embrace transformation

10. Stage 1: Continuous Delivery
“Lift and Shift” to modern platforms
Applications stay the same
Release speed massively increases

11. Writing fast cloud native applications easy
Rule #1: Don’t write slow code

12. Control code complexity
N+1 interaction patterns - control flow design
Duplicate interactions - bounded context, SPOF
More than 10 service hops - hard to debug
Highly asynchronous - hard to understand
Unusual Log Activity

13. Continuous Performance Management

14. Stage 2: Refactoring towards Micro Services
First micro services
Scheduling and Orchestration
Architectures become polyglot
Independent Release Cycles

15. Writing fast cloud native applications easy
Rule #1: Don’t write slow code
Rule #2: Don’t write code that doesn’t scale

16. Control Environment Complexity
Service Call Payload - < 500 kb
Chatty services - > 50 service calls
Inter-tier heavy interactions - granularity and locality
Status Codes - only Ok is 200

17. Understand Micro Service Interactions

18. Stage 3: Dynamic Micro Services
Up and down scaling near real time
Advanced resilience mechanisms
Infrastructure totally abstracted

19. Writing fast cloud native applications easy
Rule #1: Don’t write slow code
Rule #2: Don’t write code that doesn’t scale
Rule #3: Understand application behavior

20. Watch your application live
Health monitoring – symptoms
Orchestration monitoring - causality
Application monitoring - root cause

22. 7:00 a.m.
Low Load and Service running
on minimum redudancy
12:00 p.m.
Scaled up service during peak load
with failover of problematic node
7:00 p.m.
Scaled down again to lower load
and move to different geo location
Deployments are no longer static

23. You don’t fly by hand here
820 Billion
dependencies
Network Problem
Mushroom cloud effect

24. Container Network Monitoring

25. Make it part of your environment

26. Thank you!
