AWS Lambda Reviews & Product Details

AWS Lambda lets you run code without provisioning or managing servers. You pay only for the compute time you consume - there is no charge when your code is not running. With Lambda, you can run code for virtually any type of application or backend service - all with zero administration. Just upload your code and Lambda takes care of everything required to run and scale your code with high availability. You can set up your code to automatically trigger from other AWS services or call it directly from any web or mobile app.

"Serverless compute at the core of AWS"

4.5/5

What do you like best about AWS Lambda?

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.

What do you dislike about AWS Lambda?

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.

What problems is AWS Lambda solving and how is that benefiting you?

AWS Lambda eliminates the operational burden of server management and infrastructure scaling, allowing teams to focus on application logic. It is effective for event driven data processing, such as transforming, analyzing, or reacting to changes in data stores and streams in near real time.

Lambda is widely used to build scalable APIs with API Gateway, handle HTTP requests at any volume, and automate routine tasks like scheduled jobs and backups.

The platform accelerates prototyping and iteration, with rapid code deployment and seamless rollback through versioning. Integration with AWS services enables resilient, composable architectures that connect cloud native applications across the ecosystem.

For infrequent or bursty workloads, cost savings are significant, as compute resources are consumed only during execution. Lambda is particularly suitable for microservices, webhooks, chatbots, IoT backends, and real time analytics where elasticity and event driven design are priorities.

✅ In summary, AWS Lambda is a foundational service for serverless application development on AWS, best suited for scenarios where elasticity, event driven architecture, and operational simplicity are more valuable than long running processes or stateful computation. While not universally applicable, it delivers tangible benefits for agile, cost aware, and scalable cloud projects. Review collected by and hosted on G2.com.

"Best for serverless workflows"

4.5/5

What do you like best about AWS Lambda?

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.

What do you dislike about AWS Lambda?

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.

"AWS Lambda a powerful scalable and flexible service"

5/5

What do you like best about AWS Lambda?

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.

What do you dislike about AWS Lambda?

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.

What problems is AWS Lambda solving and how is that benefiting you?

Lambda is allowing me to have a backend logic without having to create server for the same.

Also as i used this in API gateway if i had a server the cost be high as the server will always be in use but now in this case the cost only comes when the lambda function is invoked.

And in my other use case lambda also works as custom logging to capture specific data. Review collected by and hosted on G2.com.

"Efficient Serverless Functions with Simple Setup"

4.5/5

What do you like best about AWS Lambda?

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.

What do you dislike about AWS Lambda?

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

"Lambda is best for Event Driven Job"

5/5

What do you like best about AWS Lambda?

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.

What do you dislike about AWS Lambda?

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.

What problems is AWS Lambda solving and how is that benefiting you?

I’m using an event-driven architecture for my data lake, and I’ve also used Lambda functions to perform some data transformations. Since I know my jobs finish within 15 minutes, Lambda is a great fit. It's easy to use and offers good flexibility, which makes it a preferred choice for my use case.

"Great serverless compute services"

5/5

What do you like best about AWS Lambda?

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.

What do you dislike about AWS Lambda?

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.
