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.

Best and Cost effective serverless service. Can integrate with many service in AWS. Review collected by and hosted on G2.com.

Will be helpfull only when we use aws service. Tough to integrate 3rd party cloud services. Time limit can be increased for processing Review collected by and hosted on G2.com.

AWS Lambda delivers a fully managed compute service that automatically runs code in response to events, without requiring server provisioning or ongoing maintenance.

The event driven architecture supports integrations with services like S3, DynamoDB, API Gateway, SNS, and SQS, which simplifies building complex, scalable workflows.

Multiple programming languages are supported, including Python, Node.js, Java, Go, C#, and PowerShell, with deployment options for both .zip archives and container images.

Elastic scaling is inherent; the platform adjusts capacity instantly to handle workloads ranging from a few invocations daily to thousands per second. Performance remains consistent, and availability is managed by AWS.

Environment variables, layers for shared code, and versioning streamline application configuration and deployment. Security is robust, with granular IAM controls, code signing for production compliance, and options for VPC integration and file system access where needed.

Lambda SnapStart reduces cold start latency for Java functions, and response streaming enables efficient handling of large payloads in APIs and data processing. Review collected by and hosted on G2.com.

Lambda functions are stateless by design, so persistent local state requires integration with external storage services, adding architectural complexity.

Native monitoring tools are basic, and operational visibility often needs supplementation with third party solutions.

Cost optimization requires attention to avoid unexpected charges from irregular usage patterns. Review collected by and hosted on G2.com.

One of the advantages is that it supports a wide range of programming languages, making it easier to run various applications. Additionally, the cost of invoking workflows that need to be triggered is relatively low. It also offers seamless integration with several other AWS services, such as S3, EventBridge, and API Gateway. Review collected by and hosted on G2.com.

For programs that require secrets, it is necessary to read parameters from SSM each time, which causes the Lambda response to be relatively slow. Review collected by and hosted on G2.com.

I've been using AWS Lambda extensively for handling API Gateway authentication it works for my custom auth via application and in other scenarios sending emails via SES it was very easy to implement and also the custom logging solutions. As i used other AWS services such as SES , API Gateway all the integration was very easy to use. Review collected by and hosted on G2.com.

Sometimes the IAM auth can be little tricky while implementing other service as there can be some specific permission that are required to make it work. Logging can be little tricking as the logs are sent to cloudwatch and locating something little can be a hassle. Review collected by and hosted on G2.com.

I like that AWS Lambda offers a serverless and event-driven compute model, making it easy to maintain code on the cloud. I also appreciate its automatic scalability on my platform. The initial setup is very simple compared to other tools in the market. Review collected by and hosted on G2.com.

I have issues with execution limitations and durations for my batched jobs. Review collected by and hosted on G2.com.

Feasibility to perform any task whichever can complete in 15 minutes i always recommend to go for aws lambda Review collected by and hosted on G2.com.

Time limit is the main thing because of which we can use lambda only for small jobs also cold start is the problem i faced sometimes when we are triggering after long time Review collected by and hosted on G2.com.

This tool is perfect because it relieves the burden and makes it easier to run the code without supervision and managing services. Review collected by and hosted on G2.com.

When you call a Lambda function for the first time after a while of not using it, it may take longer to run because AWS has to set up the execution environment. These delays can make the user experience less joyful for apps that need low latency. Review collected by and hosted on G2.com.

AWS Cloud is scalable , reliable and has massive service ecosystem. It allows you to spin up environments within minutes and automate deployments with cloud formation of terraform and manage infrastructure through a highly configurable IAM model Review collected by and hosted on G2.com.

The pricing structure can be confusing and hard to estimate for complex setups Review collected by and hosted on G2.com.

Users appreciate Lambda's straightforward configuration, enabling quick deployment of applications without the need to manage servers. Many reviewers highlight its intuitive interface, especially for those familiar with serverless architectures. Review collected by and hosted on G2.com.

Lambda imposes restrictions on memory, storage, and payload size, which may not be suitable for large or long-running tasks. Additionally, there's a 15-minute execution time limit, which can be a constraint for certain applications. Review collected by and hosted on G2.com.
