Cluster Placement Group:

Cluster placement groups are used to ensure low-latency networking between EC2 instances. They place instances physically close to each other within the same Availability Zone.

Steps:

Go to the AWS Management Console.

Navigate to EC2 and select "Placement Groups."

Create a new cluster placement group.

Back up the existing EC2 instance to an AMI.

Launch new EC2 instances from the AMI into the cluster placement group.

Ensure all instances are in the same Availability Zone.

To remediate the InsufficientInstanceCapacity error when scaling the Auto Scaling group, the SysOps administrator can take the following actions:

Change the Instance Type:

Insufficient capacity errors can occur if there is not enough available capacity for the specified instance type in the selected Availability Zone.

Changing to a different instance type might resolve the capacity issue.

Here are the steps to configure an Amazon S3 bucket to serve a static error page in the event of a failure at the primary site:

Log in to the AWS Management Console and navigate to the S3 service in the us-east-2 Region.

Find the existing S3 bucket named lab-751906329398-26023898.com and click on it.

In the "Properties" tab, click on "Static website hosting" and select "Use this bucket to host a website".

In "Index Document" field, enter the name of the object that you want to use as the index document, in this case, "index.html"

In the "Permissions" tab, click on "Block Public Access", and make sure that "Block all public access" is turned OFF.

Click on "Bucket Policy" and add the following policy to allow public read access:

{

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

"Statement": [

{

"Sid": "PublicReadGetObject",

"Effect": "Allow",

"Principal": "*",

"Action": "s3:GetObject",

"Resource": "arn:aws:s3:::lab-751906329398-26023898.com/*"

}

]

}

Now navigate to the Amazon Route 53 service, and find the existing hosted zone named lab-751906329398-26023898.com.

Click on the "A record" and update the routing policy to "Primary - Failover" and add the existing ALB as the primary record.

Click on "Create Record" button and create a new secondary failover alias record for the domain lab-751906329398-26023898.com that routes traffic to the existing S3 bucket.

Now, when the primary site (ALB) goes down, traffic will be automatically routed to the S3 bucket serving the static error page.

Note:

You can use CloudWatch to monitor the health of your ALB.

You can use Amazon S3 to host a static website.

You can use Amazon Route 53 for routing traffic to different resources based on health checks.
