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. You can save hundreds doing this.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. Either use the Scheduler or create a script to shut down the VM when it's not in use and turn it back on when you are going to be using it. If you are going to go for a dedicated or reserved host/instance. Reserved is cheaper (can be up to 70% + cheaper) and is recommended for LONG TERM USE. The difference is dedicated is indeed hardware assigned for you specifically but it's the most expensive model and recommended for only short-term use. You'd think dedicated means you are 'dedicated' resources on a bare metal system that has 24/7 stable running operations and you'd think reserve means those resources are reserved when needed but not 100% dedicated.

Their terminology is downright retarded.įor example. I know AWS-certified engineers that say it took them 6 months of using AWS every day to finally understand the majority of what Amazon was trying to do with AWS. If you want to find instance types and their pricing you can look here. I'm assuming this is the estimated cost if the machine was left on 24/7. It should give you a good estimate of the monthly cost. Select 'create estimate' in AWS Services search box search for 'dedicated' select on Amazon EC2 Dedicated Hosts 'configure'įrom here you can select the instance, pricing model, and storage amounts. If you want a more accurate estimate on pricing. Dedicated Hosts are the most expensive pricing AWS has to offer and thats mainly for the above reasons. Which is needed for more recent Microsoft Licensing (aka licensing based on cores). The only way to 'bring your own licensing' is on a EC2 Dedicated Host as dedicated hosts will actually show the physical cores. If you use the AWS standard calculator it is for AWS EC2 instance with Window OS licensing cost included. I know this is an older post but I just had to research this for a client so though I'd spill the beans on my research to answer your question.
