How to Reserve a Running Amazon EC2 Instance: A Guide for Data Scientists
As data scientists, we often use Amazon EC2 (Elastic Compute Cloud) instances for our compute needs. But what if we want to reserve a running instance? This blog post will provide a step-by-step guide on how to do just that.
What is an Amazon EC2 Reserved Instance?
An Amazon EC2 Reserved Instance (RI) is a reservation of a specific instance type in a specific region for a predefined term. This can range from one to three years. RIs provide substantial savings compared to On-Demand instances, making them a cost-effective choice for long-term projects.
Why Should You Reserve an Instance?
By reserving an instance, you can save up to 75% compared to the cost of On-Demand instance usage. This can significantly lower your Amazon EC2 costs. Moreover, it ensures that you have capacity reservation, giving you confidence in your ability to launch instances when you need them.
How to Reserve a Running Amazon EC2 Instance
Step 1: Open the Amazon EC2 Dashboard
Start by logging into your AWS Management Console. Click on ‘Services’ at the top of the page, and then select ‘EC2’ under the Compute section.
Step 2: Navigate to Reserved Instances
In the EC2 Dashboard, find the ‘Reserved Instances’ option in the left-hand menu and click on it.
Step 3: Choose an Instance to Reserve
If you have running instances that you want to reserve, click the ‘Reserve now’ button next to the instance. If you don’t have a running instance, you can still reserve one by clicking on ‘Purchase Reserved Instances’.
Step 4: Configure Reserved Instance
In the next screen, you will need to choose your settings for the Reserved Instance. These settings include instance type, platform, term (1 or 3 years), offering class (Standard or Convertible), and offering type (All Upfront, Partial Upfront, or No Upfront).
Step 5: Add Reserved Instance to Cart
After you’ve configured your Reserved Instance, click ‘Add to Cart’.
Step 6: Review and Purchase
Review your Reserved Instance settings in your cart. If everything is correct, click ‘Purchase’. You’ll see a confirmation message once the purchase is successful.
Final Thoughts
Reserving an Amazon EC2 instance can provide significant cost savings and capacity reservation. This guide has provided you with a step-by-step process to reserve a running instance. As data scientists, being able to manage our resources effectively is crucial, and understanding how to reserve instances is part of that toolkit.

Remember that reserved instances don’t start or stop your instances; they apply a billing discount to the running On-Demand instances that match your reservation. So, make sure you manage your instances effectively. Happy computing!
