Increasing the size of the 1 GiB EBS volumes will increase the IOPS capacity of the volumes, which will improve the I/O performance of the EBS volumes. This option does not require any changes to the instance types or EBS volume types, so it can be done quickly without the need for lengthy acceptance tests to validate that the company's applications will function properly.

To allow on-premises servers to resolve DNS records in an Amazon Route 53 private hosted zone via AWS Direct Connect, the following step should be taken:

A: Create a Route 53 Resolver inbound endpoint and attach a security group that allows inbound traffic on TCP/UDP port 53 from the on-premises DNS servers. This setup enables the on-premises DNS servers to forward DNS queries to AWS for the domains managed by Route 53. The inbound resolver endpoint acts as a bridge between the on-premises network and AWS for DNS resolution. Additional guidance on setting up Route 53 Resolver endpoints can be found in AWS documentation Route 53 Resolver.

If a Lambda function is not being invoked by an Amazon EventBridge (formerly CloudWatch Events) rule, the likely issue is a missing permission. The Lambda function needs permission to be invoked by the EventBridge rule.

Steps:

Add Permission to Lambda Function:

Open the AWS Lambda console.

Select your Lambda function.

Choose "Configuration" and then "Permissions".

Under the "Resource-based policy" section, add a policy that grants EventBridge permission to invoke your function.

Example policy:

{

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

"Statement": [

{

"Effect": "Allow",

"Principal": {

"Service": "events.amazonaws.com"

},

"Action": "lambda:InvokeFunction",

"Resource": "arn:aws:lambda:REGION:ACCOUNT_ID:function:FUNCTION_NAME",

"Condition": {

"ArnLike": {

"AWS:SourceArn": "arn:aws:events:REGION:ACCOUNT_ID:rule/RULE_NAME"

}

}

}

]

}

Verify the EventBridge Rule:

Open the Amazon EventBridge console.

Select the rule that targets your Lambda function.

Ensure that the rule is correctly configured to match events and the target is your Lambda function.

Specifying the capacity-optimized allocation strategy for Spot Instances and adding more instance types to the Auto Scaling group is the best action to meet the requirements. Increasing the size of the instances in the Auto Scaling group will not necessarily help with the launch time or reduce interruptions, as the Spot Instances could still be interrupted even with larger instance sizes.
