We performed a comparison between Amazon EC2 Auto Scaling and AWS Lambda based on our users’ reviews in four categories. After reading all of the collected data, you can find our conclusion below.
Comparison Results: Both products are very effective in providing compute service (IaaS) solutions. AWS Lambda slightly nudges ahead of Amazon EC2 Auto Scaling as many users feel it is easier to code using the solution. AWS Lambda is serverless, server configuration is not required, and can easily run it directly anywhere.
"Sometimes, Auto Scaling is more beneficial, and sometimes, Reserved Instances are preferred, especially for longer-term usage."
"It has the best auto-scaling features."
"The most useful feature is elasticity. You can scale up or down based on traffic."
"The support from Amazon EC2 Auto Scaling is very good."
"We use the solution to increase CPU and memory size."
"Auto-scaling is a good feature."
"The initial setup is straightforward."
"The solution is scalable."
"It is my preferred product, as it provides me with source code within the solution."
"The most valuable feature of AWS Lambda, from a conceptual point, is its functions. For example, it's mathematical templates into which you can write, and create your solution. You write small pieces of a solution under given parameters."
"I think the most valuable feature is the agility of the solution."
"One of the most valuable features of AWS Lambda is the performance. Lambda is very technical and has very high performance, as well as good real-time performance."
"The support from AWS Lambda is very good, they are responsive."
"We are building a Twitter-like application in the boot camp. I have used Lamda for the integration of the post-confirmation page in the application. This will help you get your one-time password via mail. You can log in with the help of a post-confirmation page. We didn’t want to setup an instance specifically for confirmation. We used the Lambda function so that it goes back to sleep after pushing up."
"Thanks to this solution, we do not need to worry about hardware or resource utilization. It saves us time."
"The tool scales automatically based on the number of incoming requests."
"Could integrate more with other platforms."
"Automation is very hard."
"Its stability and scalability need improvement."
"The product should improve vertical scaling features."
"The launch configuration feature doesn't work properly. It needs to improve the load configuration feature along with launch templates. The tool needs to tag feature as well."
"Scalability can be improved."
"The primary area for improvement is the pricing model."
"The spinning up in the solution can be much faster...The product should have a faster scalability option."
"The solution should continue to streamline integrations with AWS services."
"AWS Lambda can improve its file system-based sharing capabilities and restrictions."
"If it is a specific ETL process or a long-term one, then AWS Lambda is not a good option."
"Lambda could be improved in the sense that some of the things done with Lambda function take some time. So the performance could be better and faster."
"The product could make the process of integration easier."
"Memory limitation is one of the weaknesses of AWS Lambda and as a result, we have to use several Lambda, instead of just one. Recently, I met with an Amazon employee, who is responsible for Lambda as a product. It appears Amazon has some plans with Lambda, so I don’t have to add something to the additional features."
"AWS Lambda could be improved by increasing the size of the payload. Also, sometimes Lambda doesn't implement well for bigger solutions."
"There are other similar solutions, such as Google Cloud Platform or Microsoft Azure. They might be better for small tasks."
Amazon EC2 Auto Scaling is ranked 2nd in Compute Service with 36 reviews while AWS Lambda is ranked 1st in Compute Service with 70 reviews. Amazon EC2 Auto Scaling is rated 8.8, while AWS Lambda is rated 8.6. The top reviewer of Amazon EC2 Auto Scaling writes "Well-documented setup process and highly stable solution". On the other hand, the top reviewer of AWS Lambda writes "An easily scalable solution with a variety of use cases and valuable event-based triggers". Amazon EC2 Auto Scaling is most compared with AWS Fargate, AWS Batch, Amazon Elastic Inference, Oracle Compute Cloud Service and Apache NiFi, whereas AWS Lambda is most compared with AWS Batch, Apache NiFi, Apache Spark, AWS Fargate and Google Cloud Dataflow.
