In the case of an internal application (accessed by an employee, such as an HR system or an internal company), a blog can tolerate some downtime. Achieving high availability is directly associated with cost, so a solution architect must always plan for high availability, as per the application requirements, to avoid over-architecting.

To achieve a high availability architecture, it is better to plan workloads in the isolated physical location of the data center so that, should an...
