Reliability testing
Periodic testing should be conducted to revisit your design decisions. During testing, we need to confirm the availability and recovery targets are met. If there is a need to improve your architecture, then you should do that. Key Azure services that will be used for building reliability are as follows:
- Azure Site Recovery: To replicate VMs to a secondary region and in case of a disaster, we can easily bring up the VM from the DR region.
- Azure Pipelines: In the Operational Excellence and Performance Efficiency chapters, we saw how Azure Pipelines can be used to implement continuous testing, continuous integration, and continuous delivery. With the help of pipelines, we can validate the reliability of the code and delivery.
- Azure Traffic Manager: This is a DNS-based load balancer that offers different routing methods, such as priority, weighted, performance, and geography routing, which can be used with applications deployed across multiple regions...
