Planning to build a resilient platform
This section will design a solution for the application platform on IBM Cloud. BC refers to the capabilities of any mission-critical workload in that it can never go down or be unavailable for any reason. In addition, there are some other expectations, as follows:
- The business will not be hampered due to the unavailability of systems.
- End users will receive immediate responses at all times.
- For end users, the failure will not be visible. In the case of any system being unavailable, it will be possible to respond to the end user seamlessly by using alternative systems.
- For mission-critical workloads for the end user, there will be zero downtime. We can define a mission-critical workload as one where the application, database, or web server meets at least one of the following criteria:
- HA architecture such as clustering and hot standby.
- 24/7 support and callouts for both phase 1 (P1) and phase 2 (P2) problems.
- Support prioritized...
