Presenting Microservices platform concepts and principles that I have deployed recently.

1. [ EVE Platform ]
Concepts, Principles, Future.

2. Scope of this presentation
Not about tools
it’s about architecture

3. Architecture Principles & Concepts
1. Infrastructure as a Code
2. Automation
3. Immutability
4. Distributed (Characteristics)
5. Deployment Strategies
6. Cloud based
7. Developer friendly
8. Future

4. 1. Infrastructure as a Code
- Defining the infrastructure as DSL
- Document all the changes
- Sharing, Reviewing

5. 2. Automation
“Automation is easy, Architecture is hard”
- Chef for automation
- Keep things simple!
- Local vs Cloud system simulation on Docker
- Community cookbooks

6. 3. Immutability: Platform
- Minimal Chef usage - only 130 commits!
- Love immutable infrastructure
- Dependencies are containerized
“In the end Service come, Service go!”

7. 3. Immutability: Services
- Docker is immutable* too
- Immutability = Confidence

8. 4. Distributed
A. Resource Sharing
B. Openness
C. Concurrency
D. Scalability
E. Fault Tolerance
F. Transparency

9. A. Resource Sharing
- Think about your microservice in terms of computing
resources required, defined by SLA.
- (Service footprint + SLA) = Data Driven Scalability. No
magic scaling, No guessing.
- High resource utilization across the cluster; saves
money!

10. B. Openness
- Mesos Frameworks
- Big data frameworks are first class citizens

11. C. Concurrency
- Multiprocessing, Parallel execution!

12. D. Scalability
- How the system handles scalability?
- 10,000s Nodes!

13. E. Fault-Tolerance
“Computers fail all the time!”
- we need redundancy, we need recovery!

14. F. Transparency
- Access to the scheduled processes
- Service Discovery
- Capacity metrics
- Cluster members details

16. 5. Deployment Strategies
- Rolling Deployment
- Rollback functionality
- Deployment versioning
- Deployment dependencies
- Instant re-scheduling upon failure
- Docker as a first class citizen

17. 6. Cloud Based
- Virtual Private Cloud (VPC)
- Only 2 IPs are exposed to the public
- Public & Private subnets
- Split-Horizon DNS (*.internal.domain)

18. 7. Developer Friendly :)
- Create a new project
- Deploy from anywhere
- From any branch
- In few minutes!
- Ask Ben! for test deployment

19. The System

21. 8. EVE Future
- EVE is still young
- We find bugs, bugs get fixed
- More features in the pipeline
- EVE will graduate from PaaS to SaaS

22. 8. Team Future
- Continuous learning
- Continuous collaboration
- Continuous improvements
- Continuous happiness

23. Thanks!
