AWS Lambda Reviews & Product Details

In my current role as a QA Test Engineer at Aarete Technosoft Pvt. Ltd., we’ve integrated AWS Lambda into our automation framework to support Selenium-based UI testing. The best part about using Lambda is that it completely eliminates the need for maintaining dedicated test servers. No EC2 lifecycle, no infrastructure stress — just lightweight, serverless execution.

One major win for us was the ability to run multiple test cases in parallel by triggering separate Lambda functions for different test groups. We’ve integrated this into our Jenkins pipeline, so once a new build is deployed to the QA environment, Lambda is automatically triggered via API Gateway to start our automation suite — no manual steps, faster feedback.

We’ve also packaged headless Chromium and Selenium scripts using Lambda Layers, making test execution efficient and cost-effective without spinning up EC2 instances.

After test runs, logs and reports are uploaded to Amazon S3, and another Lambda function processes them, pushing summarized data into CloudWatch for trend analysis and monitoring. This seamless flow has helped us speed up regression cycles and gain real-time test visibility. Review collected by and hosted on G2.com.

While AWS Lambda has added a lot of flexibility to our Selenium automation workflows, there are a few limitations I’ve observed in our project at Aarete Technosoft Pvt. Ltd. that impact the testing experience:

1.When a function hasn’t been invoked in a while, there’s a cold start delay. This is particularly noticeable in our CI/CD pipelines where fast feedback matters. Even a few extra seconds per function adds up during regression runs.

2.Since Lambda runs are headless and non-interactive, debugging flaky UI issues becomes harder without a live browser view. We rely entirely on logs and screenshots saved to S3.

3.Lambda’s 15-minute timeout can be a challenge for long-running Selenium suites, especially if a test involves waiting for backend jobs or heavy UI flows. Review collected by and hosted on G2.com.

Complex pricing structure, it has costing for each and every services for if you use it for a minute or two, documentation in not very much proper in each document you have to go to another document to get more info about that. GUI changes very frequently somehow we get usedto the gui but the moment we get used to it the gui changes which make it difficult to understand the gui. support plans are costly if you want more better support for ease of implementation Review collected by and hosted on G2.com.

It is a cost-efficient product that allows you to process a number of requests for free and integrate seamlessly with almost any AWS service. All of this can be achieved within 15 minutes of execution, which is more than sufficient for many scenarios. Review collected by and hosted on G2.com.

A slow cold start is one of the main drawbacks I dislike about Lambda. I understand it's part of the service's nature, but I'm pretty sure they can find a way to make cold starts faster. Review collected by and hosted on G2.com.

Ability to quickly deploy without having any issues like managing servers, you can use it for multiple things like worker for SQS, its very easy to use in multiple languages like NodeJs, Python even Java. Review collected by and hosted on G2.com.

Execution time is max 15 minutes, so, if you have something which will take more time to process like video you can not use it in that case. Review collected by and hosted on G2.com.

You don't need to setup any software infrastructure to start building on cloud. Just create code and deploy it on AWS. Rest everything will be taken care of. AWS clouds gives you a suite of offerings that lets you choose the perfect solution for your application. Review collected by and hosted on G2.com.

There are so many things available on AWS that there is a paralysis of choice sometimes. Review collected by and hosted on G2.com.

AWS is the leading cloud provider in the market having the highest share. I find it easy to use their service because they have a good documentation on various services available on the platform.

So when you are developing a new feature, it's easy to refer and implement it in your product. Which makes integration very smooth. I use it daily in my job for various features that it provides.

It also has a good customer care support if we need to ask any queries Review collected by and hosted on G2.com.

It can be a little costly sometimes. It may not be very beginner friendly Review collected by and hosted on G2.com.

Cost-effective with on-demand requests-based billing to cut down costs of an EC2 instance which runs 24/7 and even no need for maintenance required. Able to easily handle a thousand concurrent requests and scales automatically based on incoming requests. Support for the most popular programming languages stands out from the competition. Integration with other AWS services was seamless and very helpful to build a end-to-end product. Review collected by and hosted on G2.com.

Being stateless by design, the state cannot be maintained in most places makes it necessary to store the data either in other AWS services or any external storage. As it's a cloud-based function debugging is a bit more difficult and limited access to logs makes it more difficult. An execution timeout of 15 mins makes it hard for some long asynchronous file handling process. Review collected by and hosted on G2.com.

The first thing I like about AWS cloud is it's user friendly user interface and the documentation it offers for its users.

Being the largest cloud provider, it offers vast number of features that one can implement in their software development workflows.

The learning opportunities and contents that AWS offers is very much useful to cloud learners who begin with AWS as their first cloud platform.

Easy integration with multiple other platforms makes it easier for developers to work with in their software development process and day-to-day activities utilising AWS cloud.

Implementing a new workflow in AWS is much easier and simpler compared to the competitors.

The customer support AWS offers is really fantastic, including the basic support that it offers even with free of cost. Review collected by and hosted on G2.com.

Given that AWS cloud has plenty of features, the cost of those features really comes at higher price compared to the other cloud providers such as Azure and GCP. Review collected by and hosted on G2.com.

Awesome service if you are looking for some quick quirks!! I would recommend highly if you are looking for running serverless applications which can also integrates with many AWS services like S3, DynamoDB, API gateway etc. The best thing about this service is automating things with ease and you pay only for the compute time you use.

Only disadvantage over this many advantages.. Need to perform some work around as the execution time is quite long (15 minutes). Debugging might be tricky some times as the logs are stored directly in CloudWatch and sometimes its quite difficult to debug. Review collected by and hosted on G2.com.

I've been using AWS for over 12 years, and it’s no exaggeration to say it helped shape my career. I've built products on AWS that have impacted industries and people, and the platform has never let me down. The breadth, reliability, and depth of services have made it possible to move fast, scale confidently, and bring big ideas to life.

What’s equally impressive is that their customer-centric philosophy isn’t just talk — it’s real. Every interaction I’ve had, especially in moments of need through support, has reinforced that they genuinely care about their users. Review collected by and hosted on G2.com.

I send all of my constructive feedback to the contributors and leaders at the organization. They are easy to access and they are always ready to listen. Review collected by and hosted on G2.com.
