AWS Services

Global Services
- Identity and Access Management
  - AWS IAM
    - IAM Users
      - An entity that represents a person or service (could be root user). By default root has all permissions and IAM has none. Up to 5000 users per AWS account.
    - IAM groups
      - Collections of users with policies/permissions attached to them. Cannot nest groups. Use principle of least privilege.
    - IAM roles
      - Roles define sets of permissions.  With roles you can delegate permissions to users. No credentials associated with the roles, however.
    - IAM policies
      - Policies define permissions applied to users, groups, and roles. Written in JSON. All permissions are denied by default and use the principle of least privilege.
    - IAM Best Practices
      - Lock away root user access keys
      - Create individlal IAM users
      - Use groups to assign permissions to users
      - Least privilege
      - MFA
      - Use roles for applications that run on EC2 instances
- AWS Storage
  - Amazon S3
    - Object based storage
      - Object = file
        such as .jpeg, .word, etc.
        Objects consist of:
        Key
        Value
        Version ID
        Metadata
      - Upload objects into buckets
        Buckets created in regions (even though S3 is global)
        Bucket names must be unique globally!
    - 99.999999% durability
      - Extremely unlikely that data will be lost.
    - Typical use cases:
      - Backup and storage
      - Application hosting
      - Software delivery
      - Static website
    - 6 storage classes
      - S3 standard, S3 intelligent tiering, S3 standard-IA, S3 One Zone-IA, S3 Glacier, S3 Glacier Deep Archive
    - Versioning
      - Maintains multiple variants of an object in the same bucket. Can be enabled/suspended at any time.
    - Replication
      - Requires versioning
      - Cross-region replication
        Copy objects across Amazon S3 buckets in different regions
      - Same-region replication
        Copy objects across S3 buckets in the same region
