Reserved Instance Lease Expiration In The Next 7 Days

01 Sign in to the AWS Management Console.

02 Navigate to EC2 dashboard at https://console.aws.amazon.com/ec2/.

03 In the left navigation panel, under INSTANCES section, choose Reserved Instances.

04 Open the dashboard Show/Hide Columns dialog box by clicking the configuration icon from the right menu:

05 Inside the Show/Hide Columns dialog box, select Expires checkbox then click Close to return to the EC2 dashboard.

06 Select the Reserved Instance (RI) that you want to examine and verify the value listed for the selected instance in the Expires column. If the date displayed in this column is sooner than 7 days, the selected AWS EC2 RI is about to expire, therefore it must be renewed to keep it running at the current discounted hourly rate.

07 Repeat step no. 6 to determine the expiration date for other EC2 Reserved Instances available in the current region.

08 Change the AWS region from the navigation bar and repeat the process for the other regions.

01 Run describe-reserved-instances command (OSX/Linux/UNIX) using custom query filters to list the IDs of all EC2 Reserved Instances available in the selected AWS region:

aws ec2 describe-reserved-instances
	--region us-east-1
	--output table
	--query 'ReservedInstances[*].ReservedInstancesId'

02 The command output should return a table with the requested RI IDs:

----------------------------------------
|        ReservedInstancesIds          |
+--------------------------------------+
| b847fa93-8129-491f-afbb-29ab75b7b59a |
| e527bd27-e282-4f55-b59a-0d7e09259ad7 |
+--------------------------------------+

03 Run again describe-reserved-instances command (OSX/Linux/UNIX) using your EC2 RI instance ID returned at the previous step and appropriate filtering to describe the date (timestamp) when the selected instance will expire:

aws ec2 describe-reserved-instances
	--region us-east-1
	--reserved-instances-ids b847fa93-8129-491f-afbb-29ab75b7b59a
	--query 'ReservedInstances[*].End'

04 The command output should return the date on which the reservation will expire:

[
    "2016-10-28T21:34:10.000Z"
]

05 Repeat step no. 3 and 4 to determine the expiration date for other EC2 Reserved Instances available in the current region.

06 Change the AWS region by updating the --region command parameter value and repeat steps no. 1 - 5 to perform the audit process for other regions.

01 Sign in to the AWS Management Console.

02 Navigate to EC2 dashboard at https://console.aws.amazon.com/ec2/.

07 Repeat steps no. 4 - 6 to renew (repurchase) other EC2 Reserved Instances that are about to expire, available in the current region.

08 Change the AWS region from the navigation bar and repeat the process for other regions.

01 Before you repurchase the EC2 Reserved Instance run describe-reserved-instances-offerings command (OSX/Linux/UNIX) to get the pricing details and information about available EC2 RI offerings. Use the command parameters provided in the following example to match the specifications of the RI that you want to renew (repurchase):

aws ec2 describe-reserved-instances-offerings
	--region us-east-1
	--availability-zone us-east-1a
	--instance-type "m3.medium"
	--product-description "Linux/UNIX (Amazon VPC)"
	--instance-tenancy default
	--offering-type "no upfront"
	--min-duration 2592000
	--max-duration 31536000
	--no-include-marketplace

02 The command output should return the requested offering(s) information:

{
    "ReservedInstancesOfferings": [
        {
            "OfferingType": "No Upfront",
            "AvailabilityZone": "us-east-1a",
            "InstanceTenancy": "default",
            "PricingDetails": [],
            "ProductDescription": "Linux/UNIX",
            "UsagePrice": 0.0,
            "RecurringCharges": [
                {
                    "Amount": 0.048,
                    "Frequency": "Hourly"
                }
            ],
            "Marketplace": false,
            "CurrencyCode": "USD",
            "FixedPrice": 0.0,
            "Duration": 31536000,
            "ReservedInstancesOfferingId":
            "b66073b7-b160-42b9-92b5-216e0ef2929b",
            "InstanceType": "m3.medium"
        }
    ]
}

03 Run purchase-reserved-instances-offering command (OSX/Linux/UNIX) to purchase the EC2 Reserved Instance based on the offering information returned at the previous step.

	--reserved-instances-offering-id b66073b7-b160-42b9-92b5-216e0ef2929b
	--instance-count 1

{
  "ReservedInstancesId": "ed9f760e-6f90-4551-a5f7-209e0ef2933a"
}

05 Repeat steps no. 1 - 4 to renew (repurchase) other EC2 Reserved Instances that are about to expire, available in the current region.

06 Change the AWS region by updating the --region command parameter value and repeat steps no. 1 - 5 to perform the entire process for other regions.
