This document discusses the importance of standards in software development. Some key benefits of standards include shared libraries that promote reusability, consistent security practices, a single deployment toolchain that improves developer productivity, standardized CI/CD processes that facilitate engineering onboarding, and configuration practices that allow for faster deployments and problem-solving. Overall, establishing standards across services creates a shared understanding and makes the complexity of microservice architectures more manageable.

1. Why standards matter

3. DevOps
Architecting (micro)services
Infrastructure Automation
Developer Productivity

4. DevOps
Debugging all layers
Incident Management
Cost Management

7. Shared Libraries aka Reusability
E.g.
Redis/MySQL/xyz connection manager
In memory caching
Image transformations

8. Security
E.g.
Consistent Firewall rules
Standard input sanitization
Centralized Alerting

9. Developer Productivity
No surprises when navigating the system
e.g.
All services log to /var/log
One deploy toolchain to rule them all

10. Cost Optimization
Engineering cost > Infrastructure cost
Better Standards = Lesser Engineers

11. CI/CD
Standard pathway for all services
Unit Tests
Integration Tests

12. Engineering Onboarding
Start early, start better.
Raise the bar with new hires.

13. Consistent Naming
Service name = Docker name = Repo name
= monitoring namespace = load balancer name
= CI name

14. Standard Provisioning
Ansible/Chef etc.
Docker - use and throw.

15. Standard Configuration
Consul, Zookeeper etc.
Hot reloadable configuration
Deploy faster, fix faster

16. DevOps as a Shared Bus
Identify patterns across all services
Easier to handle complexity of microservices
Ability to debug at any level

17. DevOps as a Shared Bus
Small teams with more context and communication
are better than large teams with no communication
Work closely with developers

18. Enforce Standards
But with logic and common sense.
(and some love, for our developers)

19. Its all about
Give and Take.
