This is a summary of the talk by James Birnie given at SC London 2019.
“What is an architecture?” and “What is an architect?” are the main questions around which James’ talk resolved.
- The decision about which database to choose for a company was relevant in the old days. Since ‘cloud’ it’s not anymore. Teams need to be able to decide themselves which DB fits their needs.
- Custom Frameworks are often introduced because of a lack of trust. That’s not the right solution and will not necessarily lead do less bugs / releases.
We can use metrics to determine how good our architecture actually is. He referred to ‘Accelerate’ (the science of devops, book), which describes the following metrics:
- Lead time
- Deployment frequency
- Mean time to restore
- Change fail percentage
