To provide the ability to recover deleted EBS snapshots for a specified period, creating a Recycle Bin retention rule for EBS snapshots is the appropriate solution.

Recycle Bin:

The Recycle Bin for Amazon EBS snapshots allows you to recover snapshots that were deleted within a specified retention period.

Creating a Retention Rule:

Open the Amazon Data Lifecycle Manager console.

Create a new Recycle Bin retention rule for EBS snapshots and specify the desired retention period.

Adding a Route to the Route Tables:

When new subnets are created, they need appropriate routing to ensure communication with on-premises networks.

Steps:

Go to the AWS Management Console.

Navigate to VPC.

Select the route table associated with the new subnets.

Choose "Edit routes."

Add a new route with the destination CIDR block of the on-premises network.

For the target, select the virtual private gateway (VGW).

This ensures that traffic destined for the on-premises network is routed correctly through the VPN connection.

When setting up an AWS managed VPN connection and creating a customer gateway resource, if the customer gateway device resides behind a NAT device, you should use the public IP address of the NAT device. This is because the VPN connection from AWS will be established to the public IP address that AWS can reach.

Identify the Public IP Address of the NAT Device:

Determine the public IP address assigned to the NAT device in front of the customer gateway.

Create Customer Gateway Resource:

Navigate to the VPC console in the AWS Management Console.

In the navigation pane, choose "Customer Gateways" and then click "Create Customer Gateway".

Enter a name for the customer gateway.

For the "IP Address", enter the public IP address of the NAT device.

Configure VPN Connection:

Create a VPN connection by navigating to the "VPN Connections" section and clicking "Create VPN Connection".

Select the created customer gateway and complete the VPN setup wizard.

Update Routing and Configuration:

Ensure that the routing configurations on both the AWS side and the on-premises side are updated to route traffic through the VPN connection.

Configure the customer gateway device (behind the NAT) to accept traffic from the NAT device and route it appropriately.

To record all S3 API activity, the SysOps administrator should create an AWS CloudTrail trail to log data events for all S3 objects. This solution provides comprehensive logging of all API activities at the object level within S3 buckets.

AWS CloudTrail:

CloudTrail allows you to log, continuously monitor, and retain account activity related to actions across your AWS infrastructure.

It records all API calls for Amazon S3 objects, providing a detailed history of changes made to S3 resources.

Configuration Steps:

Go to the CloudTrail console and create a new trail.

Enable data events and specify the S3 buckets to monitor.

CloudTrail will then record S3 object-level API operations such as GetObject, DeleteObject, and PutObject.

To implement a caching service while maintaining high availability for an Amazon RDS DB instance, the combination of Amazon ElastiCache for Redis and enabling Multi-AZ for the data store will meet these requirements.

Create an Amazon ElastiCache for Redis Data Store:

Redis is an in-memory data structure store that can be used as a database, cache, and message broker. It provides high availability through its replication feature.

Go to the ElastiCache console.

Choose "Create" and select "Redis."

Configure the Redis cluster with the required parameters.

Enable Multi-AZ for the Data Store:

Multi-AZ deployment provides enhanced availability and durability for Redis. In case of a failure, it automatically fails over to the replica node.

During the creation of the Redis cluster, enable Multi-AZ.

This ensures that there is a standby replica in another Availability Zone, providing high availability.
