• 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

• Evaluation
