+- ## 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
+  id:: 65120d55-d904-4ef5-bbbb-647bf02e05c9
+- 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
+- **50%** - project
+	- min: 10 values
+	- checkpoint 1: 17/11/2023
+	- checkpoint 2: 07/12/2023
+	- final report: 19/12/2023
+	- presentation: 08-12/01/2024 (week)
+- **50%** - written exam
+	- min: 8 values
+	- 12/12/2023
