AWS EC2 instance purchasing options
When it comes to purchasing options for AWS EC2 instances, there are a few things you need to take into account. In this article, we’ll go over the different options available to you, so that you can make the best decision for your needs.
On-Demand
If you need your instances immediately and are willing to pay a premium for the convenience, on-demand instances are the way to go. You’ll pay by the hour, and prices will vary depending on the instance type you choose.
Spot Instances
Spot instances are a great way to save money if you’re willing to be flexible with your instance usage. With spot instances, you’ll bid on unused EC2 capacity. If your bid is higher than the current spot price, your instances will be provisioned. If the spot price goes up, your instances may be terminated. Spot instances are perfect for batch jobs or flexible workloads.
Reserved Instances
If you know you’ll be using a certain amount of EC2 capacity for an extended period of time, you can purchase reserved instances. With reserved instances, you’ll pay a lower hourly rate than you would for on-demand instances. You can purchase reserved instances for one or three years.
Dedicated Hosts
If you need instances that are isolated from other customers for security or regulatory compliance reasons, you can purchase dedicated hosts. With dedicated hosts, you’ll pay for the entire physical server, regardless of how many instances you run on it.
Now that you know the different purchasing options for AWS EC2 instances, you can decide which option is best for your needs. If you need instances right away and are willing to pay a premium, on-demand is the way to go. If you’re willing to be flexible with your instance usage, spot instances can save you money. If you know you’ll be using a certain amount of EC2 capacity for an extended period of time, reserved instances can save you money. If you need instances that are isolated from other customers, dedicated hosts are the way to go.
