Learning azure as cloud services.
- Fault domain - Rack, common power source
- Update domain - group of connected hardware that can undergo update, maintaineance at the same time.
- Availability set - collection of fault domain and update domain in the same zone.
- Availability zone - deploy identical VM into separate availability zones which separates the fault domain and update domain.
- ARM - JSON template that can be used to create resources.
- Virtual Machine scale set - the scale set is to group vm into one image. it can be loaded up or loaded down. Use load balancer before the scale set.
- Networking in Azure & Cloud in General. Sheet
- Data/databases in Azure Sheet
- Messaging in Azire Sheet
Make sure the VM are spread across Fault domain and Update domain.
