Instances such as m5a are AMD Instances, if your workload is sensitive to numerical differences (i.e. financial risk calculations, industrial simulations) mixing these instance types might not be appropriate. While in this example we have restricted our selection to similar instances and pools of the same size (of memory and vCPUs), in production workloads the recommendation is to increase the instance selection by adding other sizes that respect the same vCPU to memory ratio. As a summary of Spot Best practices selection for ECS Auto Scaling Groups and Capacity Providers : a) Use different AZ’s b) Diversify across multiple instance types-pools c) Diversify using multiple generation of similar hardware that keep the multiplier or ratio of cpu/mem close i.e: m4.large, m5.large, m4.xlarge, m5.xlarge.

May 22, 2025 - What sets AutoSpotting apart is its ability to apply this configuration globally across your entire AWS account, eliminating the need for individual reconfiguration of each Autoscaling group. ... A spot fleet allows you to manage a collection of spot instances and (optionally) on-demand instances. With a spot fleet, you can specify how much capacity you want and define the instance types that meet your needs.

1 week ago - You can use attribute-based instance type selection (ABS), to easily express your instance requirements in the form of attributes, such as vCPU, memory, and storage, ensuring optimal flexibility of your configuration. Please visit Spot best practices to learn more about how you can improve your Spot experience.

How to Save Cost on EC2 with AWS Spot Instance Advisor

December 12, 2023 - This strategy significantly reduces the likelihood of an Auto Scaling Group (ASG) cluster being unable to acquire a Spot Instance. When choosing an instance, opt for various classes within the same series, but avoid selecting multiple types with similar service characteristics. For example, in the 7g series, choose between M7g, C7g, or R7g, but not all three. AWS likely balances these instance types across the same servers due to their similar features.

September 18, 2024 - So I'll have to create a Lambda to change the target type and monitor for availability issues. I have been watching this region and for the past several months the prices have been the same, with one AZ consistently cheaper. If I wanted to have availability guarantees, I would use one of the other spot strategy options or even an On-demand or Reserved instance.

October 10, 2023 - For a given EC2 instance type, the on-demand price is the highest and the spot price is the lowest (the reserve price is in between). AWS provides a Price List API to programmatically retrieve information on AWS products and pricing.

June 30, 2025 - Be flexible in terms of instance types and availability zones: A Spot instance pool consists of unused EC2 instances with the same instance type and availability zone. You should be flexible about which instance types you request and in which ...

January 21, 2025 - By diversifying across different instance types, you can take advantage of the unique strengths of each type, optimizing performance and cost-efficiency. Similarly, distributing your spot instances across multiple availability zones can significantly reduce the risk of interruption. If one availability zone experiences high demand or a service disruption, your application can continue to run smoothly in the other zones. Elastigroup from Spot enables users to scale workloads on spot instances in AWS, Azure, and Google Cloud, with guaranteed availability, to see a dramatic cost reduction with maximum efficiency for both stateless and stateful workloads.

1 week ago - You can use Spot Instances for various stateless, fault-tolerant, or flexible applications such as big data, containerized workloads, CI/CD, web servers, high-performance computing (HPC), and test & development workloads. ... Watch Mike North, NFL VP of Broadcasting Planning, explain how the NFL schedule was built with the help of AWS.

For more information, see View Spot Instance pricing history. We independently map Availability Zones to codes for each AWS account. Therefore, you can get different results for the same Availability Zone code (for example, us-west-2a) between different accounts. You can view the savings made from using Spot ...

December 13, 2022 - A Spot Fleet request includes the number of instances required, type of instances, the target capacity, and maximum price. EC2 tries to maintain the target capacity, adding spot instances if available, based on the request details. When spot instances are terminated, Spot Fleet attempts to replace them using the lowest price option available. While AWS Spot Fleet enables you to manage a large group or fleet of spot instances with different allocation strategies (i.e.

July 9, 2024 - But Spot Instances must be more dynamic. They must also be consistent in demanding production. Although they offer more flexibility. But, if you settle for Convertible Reserved Instances, you will still have a little wiggle room. That is if you need to shift between different instance types. On-demand instances are the primary EC2 instances on AWS...

1 week ago - We recommend that you launch your T4g or T3 Spot Instances in standard mode to avoid paying higher costs. For more information, see Surplus Credits Can Incur Charges and Spot Instance limits. The prices displayed below are the lowest prices per instance type in the region.

September 11, 2025 - Interruptions: AWS can terminate Spot Instances with just a 2-minute warning when capacity is no longer available at your bid price. This makes them unsuitable for critical or stateful workloads without fault tolerance. Unpredictable availability: Spot capacity fluctuates based on regional demand. There’s no guarantee your preferred instance type ...

1 week ago - EC2 instance types are purpose-built configurations of virtual servers, designed with different resource combinations to help your applications perform at their best.

A free and easy-to-use tool for comparing EC2 Instance features and prices.

October 7, 2025 - AWS EC2 pricing models offer multiple instance types and various options for cloud spending optimization, but managing it all on your own is not so simple. To address the challenges of cloud infrastructure management, including EC2 cost optimization, Spot offers a full suite of cloud management ...
