Account Management, Billing & Support Flashcards
(35 cards)
AWS Organizations
• Global service
• Allows to manage multiple AWS accounts
Cost Benefits:
• Consolidated Billing
• Pricing benefits from aggregated usage
• Pooling of Reserved EC2 instances for optimal savings
• API is available to automate AWS account creation
• Restrict account privileges using Service Control Policies (SCP)
Multi Account Strategies
Create accounts per department, per cost center, per dev/test/ prod, based on regulatory restrictions (using SCP), for better resource isolation (ex: VPC), to have separate per-account service limits, isolated account for logging
Use tagging standards for billing purposes
• Enable CloudTrail on all accounts, send logs to central S3 account
• Send CloudWatch Logs to central logging account
Service Control Policies (SCP)
• Whitelist or blacklist IAM actions
• Applied at the OU or Account level
• Does not apply to the Master Account
• SCP is applied to all the Users and Roles of the Account, including Root user
• The SCP does not affect service-linked roles
• SCP must have an explicit Allow
AWS Organization – Consolidated Billing
• Combined Usage: combine the usage across all AWS accounts in the AWS Organization to share the volume pricing, Reserved Instances and Savings Plans discounts
• One Bill
• The management account can turn off Reserved Instances discount sharing
