A company is migrating its databases to Amazon RDS for PostgreSQL. The company is migrating its applications to Amazon EC2 instances. The company wants to optimize costs for long-running workloads. Which solution will meet this requirement MOST cost-effectively?

Accepted Answer

Correct answer: D. The correct answer is D. Option D: Purchase Reserved Instances for a 3 year term with the All Upfront option for the Amazon RDS for PostgreSQL workloads. Purchase a 3 year EC2 Instance Savings Plan with the All Upfront option for the EC2 instances. Reserved Instances lower cost for steady-state, predictable long-running workloads. Amazon EC2 provides resizable virtual servers when you need full control of the operating system. Amazon RDS is a managed relational database that handles patching, backups and failover. This option delivers the requirement at the lowest cost.
