Essentially like a pipeline. Tell it that it will create a new image every Friday

Provides a graphical interface to create image-building pipelines
Creates and maintains Amazon EC2 AMIs and on-premises VM images

Enforces version control
Instance store is temporary. Just like memory it will be wiped once the instance is stopped
EBS is attached like a Hard Drive

You can place a script that will automatically install a webserver or specific packages on instance launch for example.
Increase network performance between instances.
An instance can be launched in only one placement group at a time.
Cluster
Reduce correlated or simultaneous failure.
Instances with a tenancy of host can’t be launched in a placement group
Partition
Spread
Cluster: Packs instances close together inside an Availability Zone. This strategy helps workloads to achieve low-latency network performance.
Partition: Spreads your instances across logical partitions so that groups of instances in one partition do not share the underlying hardware with groups of instances in different partitions.
Spread: Strictly places a small group of instances across distinct underlying hardware to reduce correlated failures.
