## Complex Structures: Challenges
|
|
|
|
|
### Deployment
|
|
|
|
|
- Multiple components with specific requirements
|
|
|
|
|
- Heterogeneous hardware, software and services (e.g., cloud computing services
|
|
|
|
|
|
|
|
|
|
### Management + Configuration
|
|
|
|
|
- Specific to each software/hardware component
|
|
|
|
|
- Optimal configurations will change over time...
|
|
|
|
|
|
|
|
|
|
### Monitoring + Benchmarking
|
2023-09-24 12:37:33 +01:00
|
|
|
- Finding anomalies (performance, failures, ...) in complex applications and infrastructures
|
|
|
|
|
|
|

|
## Agile Development
|
|
|
|
|
**Quick reaction to frequent small changes!**
|
|
|
|
|
|
|
|
|
|
- Rests on formal (versioned) source, binary and documentation repositories
|
|
|
|
|
- Unambiguous current state
|
|
|
|
|
- Ability to back track
|
|
|
|
|
- Automated build and test
|
|
|
|
|
- Fast feedback
|
|
|
|
|
- Fast iterations
|
|
|
|
|
|
|
|
|
|
## Operations
|
|
|
|
|
- Manual provisioning and configuration
|
|
|
|
|
- Informal communication between qualification and production stages
|
|
|
|
|
- Consequences:
|
|
|
|
|
- Not repeatable or reproducible
|
|
|
|
|
- Configuration drift
|
|
|
|
|
- “Snowflake” servers (don't even look at it…)
|
|
|
|
|
- Subjective monitoring
|
|
|
|
|
|
|
|
|
|
## Infrastructure as Code
|
|
|
|
|
Include infrastructure scripts in agile process!
|
|
|
|
|
|
|
|
|
|
- Hardware provisioning with scripts
|
|
|
|
|
- In contrast to: physically unboxing and plugging
|
|
|
|
|
- Software provisioning with scripts
|
|
|
|
|
- In contrast to: clicking through setup wizards
|
|
|
|
|
- Configuration with scripts
|
|
|
|
|
- In contrast to: clicking through control panels
|
