It enables users to define scaling policies that dynamically add or remove instances based on real-time metrics or predictable schedules, ensuring optimal performance and cost efficiency. Key Features and Functionality: - Automatic Scaling: Seamlessly launches new EC2 instances when demand increases and terminates unneeded instances when demand decreases, optimizing resource utilization. - Dynamic and Predictive Scaling: Adjusts capacity based on Amazon CloudWatch metrics or predefined schedules, allowing for proactive scaling in anticipation of traffic changes. - Health Monitoring and Replacement: Continuously monitors instance health and automatically replaces impaired instances to maintain desired capacity and application availability. - Multi-AZ Deployment: Distributes instances across multiple Availability Zones to enhance fault tolerance and resilience against localized failures. - Support for Multiple Instance Types and Purchase Options: Allows provisioning of various instance types and purchase options, including On-Demand and Spot Instances, to optimize performance and cost. - Integration with Load Balancing: Works with Elastic Load Balancing to distribute incoming traffic evenly across healthy instances, ensuring consistent application performance. Primary Value and Problem Solved: Amazon EC2 Auto Scaling addresses the challenge of fluctuating application demand by automatically adjusting compute capacity, ensuring applications remain responsive and cost-effective. By automating the scaling process, it reduces the need for manual intervention, minimizes the risk of over-provisioning or under-provisioning resources, and enhances overall application reliability and performance. ## Amazon EC2 Auto Scaling Pros & Cons **What users dislike:** - Users find the **complex configuration** of EC2 Auto Scaling challenging and often overwhelming for newcomers to AWS.

Useful! **Rating:** 3.5/5.0 stars **Reviewed by:** Verified User in Computer Software | Small-Business (50 or fewer emp.) **Reviewed Date:** January 08, 2023 **What do you like best about Amazon EC2 Auto Scaling?** Cost effective, do not have to manage hundreds of servers, able to manage web traffic effectively **What do you dislike about Amazon EC2 Auto Scaling?** Easy to use features - other software that does the same thing **What problems is Amazon EC2 Auto Scaling solving and how is that benefiting you?** Create big projects on my home machine ### 2. It is an efficient way to manage cost **Rating:** 4.0/5.0 stars **Reviewed by:** Fasugba B. | DevOps Engineer, Small-Business (50 or fewer emp.) **Reviewed Date:** July 06, 2022 **What do you like best about Amazon EC2 Auto Scaling?** With Amazon EC2 Auto scaling, you are able to effectively manage cost while focusing on other things **What do you dislike about Amazon EC2 Auto Scaling?** Amazon EC2 Auto scaling Need some bits of more automations **Recommendations to others considering Amazon EC2 Auto Scaling:** A trial will convince you. It safes alot of hard labour **What problems is Amazon EC2 Auto Scaling solving and how is that benefiting you?** It is helping in the stance of not having to be manually managing resource usage ### 3. Straightforward, but deep inside the AWS ecosystem **Rating:** 4.0/5.0 stars **Reviewed by:** Austin C. | Solutions Architect, Enterprise (> 1000 emp.) **Reviewed Date:** January 22, 2019 **What do you like best about Amazon EC2 Auto Scaling?** The autoscaling system is easy to use and is integrated into everything. **What do you dislike about Amazon EC2 Auto Scaling?** To use the autoscaling system pretty much everything you do has to be implemented in AWS. **Recommendations to others considering Amazon EC2 Auto Scaling:** It's definitely a commitment to use EC2 auto scaling. You have to make sure your instances are all configured for easy scaling up and down, and get all of that configuration into the AWS cloud using launch configurations and AMIs. This will require that you be pretty committed to the AWS ecosystem. So, if you're looking for a service you can use while still remaining cloud agnostic or avoiding other cloud activity, this may be difficult to take advantage of. But, if you're willing to go all in or you're already in the AWS ecosystem, then this is an excellent service that you should be using. **What problems is Amazon EC2 Auto Scaling solving and how is that benefiting you?** We use EC2 autoscaling to support dynamic scaling up and down of apps and services that have bursty or inconsistent load. ### 4. Good horizontal scaling but lacks vertical scaling for stateful applications. **Rating:** 4.0/5.0 stars **Reviewed by:** Farhad S. | Cloud Infrastructure Head, Enterprise (> 1000 emp.) **Reviewed Date:** January 24, 2019 **What do you like best about Amazon EC2 Auto Scaling?** Works great and seamlessly for horizontal scaling (increasing number of VMs based on metrics like CPU, memory, etc.) **What do you dislike about Amazon EC2 Auto Scaling?** Lack of support for vertical scaling (increase CPU and memory for same VM) for stateful application. Scaling down with horizontal scaling is unpredicatable. AWS EC2 autoscaling does offer some termination policies like oldest instance, newest instance, etc. but this still does not guarantee that the instance being terminated is not doing some task. There should be a feedback capability provided between instances and AWS EC2 autoscaling (similar to what kubernetes provides). **Recommendations to others considering Amazon EC2 Auto Scaling:** Good for simple horizontal scaling for stateless applications. I would like to see additional features for controlled scaling down. I would also like to see support for vertical scaling (preferably non disruptive). **What problems is Amazon EC2 Auto Scaling solving and how is that benefiting you?** Seamless scaling for stateless applications. ### 5. Used Auto-Scalling for more than 3 months **Rating:** 4.0/5.0 stars **Reviewed by:** Verified User in Information Technology and Services | Enterprise (> 1000 emp.) **Reviewed Date:** October 02, 2019 **What do you like best about Amazon EC2 Auto Scaling?** Like it's automatically scalling up compute instances and scalling down as I was using AWS HPC. Its gonna be very costly without Auto-Scalling. **What do you dislike about Amazon EC2 Auto Scaling?** It took some time around 1-2 minute to scale up from 0 instance. **Recommendations to others considering Amazon EC2 Auto Scaling:** Good place to start cloud computing. **What problems is Amazon EC2 Auto Scaling solving and how is that benefiting you?** It saves a lot of money. if you combined it with spot demand then it saves a huge. ### 6. Amazon EC2 Auto scaling review **Rating:** 4.0/5.0 stars **Reviewed by:** Nikhil T. | CEO, Small-Business (50 or fewer emp.) **Reviewed Date:** January 24, 2019 **What do you like best about Amazon EC2 Auto Scaling?** 1. EC2 instances are super easy to setup. 2. Loved how easily it integrates with Load balancer. 3. Deploying website through EC2 has become a breeze **What do you dislike about Amazon EC2 Auto Scaling?** 1. There are around 10 types of EC2 instances, so sometimes we become confused which one to you, considering so many options avaible. We usually use T2 Micro **What problems is Amazon EC2 Auto Scaling solving and how is that benefiting you?** Very easy to setiup and scale as compared to Azure ## Amazon EC2 Auto Scaling Discussions - [What are the two main components of AWS Auto Scaling?](https://www.g2.com/discussions/what-are-the-two-main-components-of-aws-auto-scaling) - [What are the benefits of Amazon EC2 Auto Scaling?](https://www.g2.com/discussions/what-are-the-benefits-of-amazon-ec2-auto-scaling) - [What are the three components of EC2 Auto Scaling?](https://www.g2.com/discussions/what-are-the-three-components-of-ec2-auto-scaling) - [What are the characteristics of Amazon EC2 Auto Scaling?](https://www.g2.com/discussions/what-are-the-characteristics-of-amazon-ec2-auto-scaling) - [View Amazon EC2 Auto Scaling pricing details and edition comparison](https://www.g2.com/products/amazon-ec2-auto-scaling/reviews?filters%5Bnps_score%5D%5B%5D=4§ion=pricing&secure%5Bexpires_at%5D=2026-08-13+21%3A10%3A49+-0500&secure%5Bsession_id%5D=624bab7f-bc97-4a47-aca1-a14391ea3c1c&secure%5Btoken%5D=d1fa72f2b60e92154663e36fd4360623f5bec3a2a8e2b6520221f4f18aae1166&format=llm_user) ## Amazon EC2 Auto Scaling Integrations - [Amazon EC2](https://www.g2.com/products/amazon-ec2/reviews) - [Amazon EC2 Systems Manager](https://www.g2.com/products/amazon-ec2-systems-manager/reviews) - [AWS Lambda](https://www.g2.com/products/aws-lambda/reviews) ## Amazon EC2 Auto Scaling Features **Automated resource scaling** - Automatic resource discovery - Smart scaling **Scaling strategies** - Pre-defined optimization strategies - Predictive scaling **Visualization** - Unified scaling - Dashboard ## Top Amazon EC2 Auto Scaling Alternatives - [Google Compute Engine](https://www.g2.com/products/google-compute-engine/reviews) - 4.5/5.0 (876 reviews) - [Cast AI](https://www.g2.com/products/cast-ai/reviews) - 4.6/5.0 (204 reviews) - [ScaleOps](https://www.g2.com/products/scaleops-cloud-native-optimization-scaleops/reviews) - 4.6/5.0 (96 reviews)
