17308 A 2-tier application uses a 3 node application cluster and a 2 node DB cluster. The application works only when all tiers are available. The application tier is in an active-active load-balanced configuration with the given nodes. But the database tier is in a cold standby mode where it takes 12 hours to switch bring a passive node online. If an application node fails every 10 days and a DB node fails every 100 days, find the following: [4 marks] 1. MTTF of the application tier 2. MTTF of the database tier 3. Availability of the database tier 4. Overall availability of the 2-tier system, assuming MTTR of the application tier is negligible
