Let us now look at what benefits we get by switching to reserved instances and/or savings plans. ![]() That’s our first lesson: Don’t pay on-demand prices for long-running instances! “Long-running” here means at least a year, which is very commonly the case for EC2 instances hosting websites, for example. If you have long-running instances, you can save money by switching to reserved instances or savings plans instead of on-demand pricing. So what does that mean in EC2 terms? “Bulk” in EC2 terms means the duration of your EC2 usage. With such a simple pricing structure, why would you ever need any other pricing model? The answer is simple: just like (almost) everything else in the real world, if you buy more, you pay less! In other words, if you are willing to buy something in bulk, you would pay less than the sum of the individual pieces. In this case, it would be as shown in the table below: Server There is a flat hourly charge which you add up for a month to get your total bill. Unlike reserved instances and savings plans, on-demand is very straightforward. Note: All prices in this article are in USD per month and for Linux EC2 instances in US East 1: N. Let us begin with the simplest pricing model: on-demand. The instance types of each of these are as follows: Web Server Say you have a simple webapp architecture comprised of a web server, an app server & a database server. Along the way, we will learn about the nuances of every model and get a feel for when to use which one. Let us take an example architecture and apply the pricing models to it. Therefore, this article will focus on only the first three pricing models: on-demand, reserved instances, and savings plans. Most of the EC2 usage out there is for VMs running non-interruptible workloads (like web servers) on shared-tenancy hardware. ![]() Dedicated is for when you need an entire rack just for yourself, probably for licensing or compliance reasons. Spot is for workloads that can tolerate interruptions. ![]() With so many pricing options to choose from, how do you pick the right one for your EC2 needs? QloudX is here to help! □įirst things first: both spot instances & dedicated hosts are for certain specialized needs so let’s keep them apart. For example, you can move from c5.xlarge running Windows to c5.2xlarge running Linux and automatically benefit from the Savings Plan prices.On-demand, reserved instances, savings plans, spot instances, and dedicated hosts. EC2 Instance Savings Plans give you the flexibility to change your usage between instances within a family in that region. This automatically reduces your cost on the selected instance family in that region regardless of AZ, size, OS or tenancy. For example, with Compute Savings Plans, you can change from C4 to M5 instances, shift a workload from EU (Ireland) to EU (London), or move a workload from EC2 to Fargate or Lambda at any time and automatically continue to pay the Savings Plans price.ĮC2 Instance Savings Plans provide the lowest prices, offering savings up to 72% in exchange for commitment to usage of individual instance families in a Region (e.g. These plans automatically apply to EC2 instance usage regardless of instance family, size, AZ, Region, OS or tenancy, and also apply to Fargate or Lambda usage. AWS offers two types of Savings Plans:Ĭompute Savings Plans provide the most flexibility and help to reduce your costs by up to 66%. When you sign up for a Savings Plan, you will be charged the discounted Savings Plans price for your usage up to your commitment. ![]() Savings Plans are a flexible pricing model that offer low prices on Amazon EC2, AWS Lambda, and AWS Fargate usage, in exchange for a commitment to a consistent amount of usage (measured in $/hour) for a 1 or 3 year term.
