BIG-IP Virtualized Edition (VE) is an industry-leading application delivery controller and security services platform. From providing intelligent L4-L7 load balancing, traffic management, and SSL service offload to application access, acceleration, and security, BIG-IP VE always ensures that your applications are fast, highly available, and secure. Depending on your license, you can deploy the following modules:
LTM — Intelligent L4-L7 load balancing, SSL/TLS termination and offload, health monitoring, connection state management, and application traffic programming control using F5 iRules. DNS — High performance DNS service with global server load balancing.

If you want to upgrade the BIG-IP VE in the future, select an image with 2 boot partitions. If you don't need upgrade space (and instead plan to create a new instance when a new version of BIG-IP VE is released), choose an image with 1 boot partition. Accelerate and simplify your BIG-IP VE deployment using CloudFormation templates from the F5 Networks GitHub repository. https://github.com/F5Networks/f5-aws-cloudformation
