B.Amazon EC2 Systems Manager
C.EC2 AMI`s
D.AWS Code Pipeline

Answer - B
The Amazon EC2 Systems Manager helps you automatically collect software inventory, apply OS patches, create system images, and configure Windows and Linux operating systems. These capabilities enable automated configuration and ongoing management of systems at scale and help maintain software compliance for instances running in Amazon EC2 or on-premises.
One feature within Systems Manager is Automation, which can be used to patch, update agents, or bake applications into an Amazon Machine Image (AMI). With Automation, you can avoid the time and effort associated with manual image updates, and instead build AMIs through a streamlined, repeatable, and auditable process.
