Complex Structures: Challenges
1. Deployment
- Multiple components with specific requirements
- Heterogeneous hardware, software and services (e.g., cloud computing services
2. Management + Configuration
- Specific to each software/hardware component
- Optimal configurations will change over time...
3. Monitoring + Benchmarking
- 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
DevOps
Supports fast, frequent, small changes!
- Development and deployment are self-documenting and versioned
- Deployment is reproducible and repeatable
- Servers are disposable and consistent
Roadmap
- Distributed systems architectures & deployment
- Common distribution patterns
- Reliability and scalability
- Automatic provision and configuration
- Cloud computing
- Services and abstractions
- Infrastructure management (virtualization, storage, ...)
- Monitoring and evaluation
- Monitoring frameworks and metrics
- Benchmarking
