It is mandated that the application must have minimal downtime as it receives traffic 24/7 and any downtime may reduce business revenue. The application must also be fault tolerant including the data layer. Concerns have been raised around performance of the database layer during sales events and other peak periods. The application must also be continually scanned for vulnerabilities. Which option will meet the above requirements?
