Add and edit tags for AWS resources using key-value bags to categorize by purpose, owner, and environment. Understand tag limits and how tagging aids resource search and management.

Learn how regional defaults cap EC2 instances, how to check limits, and how to request increases by instance type; explore billing reports and Ghost Explorer for usage in S3 bucket.

Explore how instance usage reports and utilization reports track capacity and capacity reservation for on-demand and reserved instances, while scheduled events and system maintenance affect instance lifecycle.

Learn to configure an auto scaling group in EC2 using CloudWatch alarms, a launch configuration, scaling policies, and a load balancer to save costs and safeguard applications.

Learn to manage an auto scaling group by launching and terminating instances in response to load, adjusting the desired and maximum instances, and using launch configurations across availability zones.

Explore Amazon S3 fundamentals: buckets, objects, storage classes, lifecycles, versioning, and access controls for scalable, durable, and cost-effective data storage.

Explore Amazon S3 bucket properties and permissions, including loading details and access controls. Learn public versus authenticated access and how to host websites.

Define Amazon S3 lifecycle rules to move or delete objects during their lifetime, enable versioning, and transition between standard, glacier, and noncurrent versions, including cleanup of incomplete uploads.
