Best Practices for Managing AWS Resources Across Multiple Accounts

Managing AWS resources across multiple accounts can sound complicated, but it’s one of the best ways to keep your cloud environment organized, secure, and cost efficient. Whether you’re a small business or a large enterprise, a multi account strategy can make it much easier to control resources, manage permissions, and track costs. If you’re looking to gain handson knowledge in this area, consider AWS Training in Bangalore to help you develop essential skills. In this post, we’ll go through some best practices for managing AWS resources across multiple accounts in a simple, effective way.

 Why Use Multiple AWS Accounts?

Before diving into best practices, let’s quickly go over why you’d want to use multiple AWS accounts:

  • Security: By separating resources into different accounts, you can contain potential security issues. If one account is affected, the others remain safe.
  • Cost Tracking: Each account can represent a project, department, or environment, making it easy to track and analyse spending.
  • Organization: Separating environments (like development, testing, and production) into different accounts makes it easier to manage resources without mixing them up.

 1. Start with AWS Organizations

AWS Organizations is a tool that makes it easy to set up and manage multiple AWS accounts under a single, centralized structure. It’s the foundation for any multi account setup. Here’s what you can do with AWS Organizations:

  •  Consolidated Billing: AWS Organizations lets you combine billing for all accounts, so you only get one bill for everything. Plus, you can see how much each account is spending, which helps with budget tracking.
  •  Organizational Units (OUs): You can group accounts by department, project, or purpose. For example, you might have an OU for development, another for production, and a third for testing.
  •  Service Control Policies (SCPs): These rules help control what each account can and cannot do. For example, you can restrict access to certain AWS services across all accounts, keeping things secure and compliant.

 2. Use Consistent Naming and Tagging

When you have multiple AWS accounts, clear and consistent naming conventions make a huge difference. Here’s how to keep things organised:

  •  Naming Conventions: Use names that describe what the account is for, like `project name environment purpose`. So, a development account for a project called “MyApp” might be named `myappdev`. This makes it easy to know what each account is for at a glance.
  •  Tags: Tags are labels you can apply to resources, like EC2 instances or S3 buckets. AWS lets you tag most resources, so use this feature to your advantage! Tags like “Environment: Production” or “Department: Marketing” can help you organise, search, and track costs.

3. Centralize Access with AWS Single SignOn

Managing access for multiple accounts can get complicated, especially if you have a large team. AWS Single SignOn (SSO) simplifies this by letting you manage access to multiple AWS accounts from a single, central place.

  •  Set Up AWS SSO: AWS SSO integrates with AWS Organizations, so you can set up one login for users and then grant them access to different accounts as needed.
  •  Use IAM Roles for CrossAccount Access: Instead of creating new users in each account, create IAM roles that allow users to access multiple accounts securely. For example, you could have a “Developer” role with limited permissions and a “Manager” role with broader permissions.

 4. Automate Account Creation with AWS Control Tower

AWS Control Tower is a tool that helps you set up and manage a secure, multiaccount environment following AWS best practices.

  •  Account Factory: This feature allows you to create accounts quickly and with consistent settings. Control Tower automatically enables useful services like CloudTrail (which tracks account activity) and GuardDuty (which monitors for security threats) in each account.
  •  Guardrails: Guardrails are like guardrails on a road—they keep things safe and within the lines. AWS Control Tower offers preconfigured guardrails that help enforce security and compliance, like requiring encryption for certain data or restricting access to sensitive resources.

 5. Centralize Logging and Monitoring

When you have resources spread across multiple accounts, centralizing your logs and monitoring helps you keep track of what’s happening. AWS offers some great tools to help with this:

  •  AWS CloudTrail: CloudTrail records account activity, so you can see who did what and when. You can centralize logs from all accounts into one main account, making it easier to monitor activity and spot any issues.
  •  Amazon Cloud Watch and AWS Config: CloudWatch lets you track the health and performance of your AWS resources, and AWS Config tracks configuration changes. Both can be set up to report back to a main account, helping you stay on top of what’s happening across all accounts.

 6. Share Resources with the AWS Resource Access Manager

Sometimes, multiple accounts need to access the same resources. AWS Resource Access Manager (RAM) lets you share resources like VPC subnets and Route 53 Resolver rules securely. If you’re interested in learning more about these practices, DevOps Training in Bangalore can provide handson experience. 

  •  VPC Sharing: Instead of creating a separate VPC in each account, you can share one in a central account. This makes it easier to manage networks and reduces the costs of maintaining multiple VPCs.
  •  Centralised Resources: Whenever possible, set up shared resources that multiple accounts can access. For instance, you might have a shared S3 bucket for logs that all accounts use.

 7. Optimize and Track Costs

Managing costs across multiple accounts can be tricky, but AWS has tools to help you keep things under control:

  •  AWS Budgets and Cost Explorer: AWS Budgets lets you set spending limits and alerts when you’re close to exceeding them. Cost Explorer helps you analyze spending trends across accounts, making it easier to spot cost savings opportunities.
  •  Tag Based Billing: By tagging resources, you can generate reports based on tags, showing costs by project, department, or purpose. This helps you understand where money is going and find areas to optimize.

Managing AWS resources across multiple accounts can improve security, simplify cost tracking, and make your environment easier to manage. 

Additionally, DevOps Training in Marathahalli can help you integrate AWS and DevOps best practices to streamline your cloud operations. By using AWS Organizations, setting up SSO, leveraging Control Tower, and centralizing logging and monitoring, you can maintain a multiaccount setup that’s both secure and efficient. 

Whether you’re just starting out or expanding your AWS environment, following these tips will help you build a strong foundation that’s easy to manage and highly effective.
