To retain application logs after instances are terminated, configure the EC2 instances to send logs to Amazon CloudWatch Logs.

Steps:

Create a New AMI:

Create a new AMI that includes the Amazon CloudWatch agent.

Install and configure the CloudWatch agent to send logs to CloudWatch Logs.

To fix the "403 Forbidden - Access Denied" error when accessing a static website hosted on Amazon S3, you need to ensure that the objects in the bucket have the appropriate permissions for public access. Here’s how to do it:

Login to AWS Management Console:

Open the Amazon S3 console at Amazon S3 Console.

Navigate to the Bucket:

In the S3 console, select the bucket hosting the static website.

Add a Bucket Policy:

Go to the Permissions tab.

Choose Bucket Policy and add the following policy to grant public read access to all objects in the bucket:

{

"Version": "2012-10-17",

"Statement": [

{

"Effect": "Allow",

"Principal": "*",

"Action": "s3:GetObject",

"Resource": "arn:aws:s3:::your-bucket-name/*"

}

]

}

Save the Policy:

After adding the policy, save the changes.

This policy ensures that all objects in the bucket are publicly accessible, resolving the 403 Forbidden error.

To optimize the routing of requests to the application for users in different geographic locations, use Amazon Route 53's latency-based routing:

Latency Routing Policy: Modify the Route 53 DNS settings for app.anycompany.com by changing the routing policy to latency. This policy routes user requests to the server that has the lowest latency relative to the user's location.

Configure Latency Records: Create latency records for each ALB—one for the ALB in us-west-2 and another for the new ALB in ap-southeast-2. Route 53 will automatically direct traffic to the endpoint that provides the lowest latency connection to the user.

Seamless User Experience: By using latency routing, the URL remains the same (app.anycompany.com), but the backend service location varies based on which endpoint is likely to respond the fastest. This setup provides a seamless experience for users, reducing latency without requiring any changes to how they access the application.

This method leverages Route 53's advanced DNS capabilities to ensure optimal performance and user experience by dynamically routing traffic based on geographic latency considerations.

To meet the requirement of consistent performance of 10,000 IOPS with the least cost, the SysOps administrator should use a General Purpose SSD (gp3) Amazon EBS volume:

General Purpose SSD (gp3) EBS Volume:

The gp3 volume type can be provisioned with the required IOPS without the need for additional capacity, making it a cost-effective solution compared to Provisioned IOPS SSD (io1) volumes.
