Management Policies The other type of policy handled by AWS Organizations is management policies, which later subdivides into artificial intelligence (AI) services opt-out policies, backup policies, and tag policies. Management policies are inherited from the root of your organization down to the account level. The effective policy being applied at the account level is the […]

DNS Logging and Monitoring Amazon Web Services has integrated Route 53 into its management applications for ease of use and insight into its operations. Since all interactions with Route 53 are an API call behind the scenes, these records can be natively sent to CloudTrail for a record of activities and analysis. The CloudWatch monitoring […]

AWS Autoscaling After you design all the instance layers to be scalable, you should take advantage of the AWS Autoscaling service to automate the scale-in and scale-out operations for your application layers based on performance metrics—for example, EC2 CPU usage, network capacities, and other metrics captured in the CloudWatch service. The AutoScaling service can scale […]

When a resolver requests a record, it will store that information locally in case it is needed again. However, if it remains in the local cache, the primary, or authoritative, server may […]

ExamAlert Remember, one of the crucial factors that enables scalability and elasticity is ensuring your resources are disposable. That means any data is always written outside the processing layer. All databases, files, logs, and any kind of output the application generates should always be decoupled from the processing layer. In the exam, different services might […]
