### "A Powerful Serverless Solution"

February 26, 2025

5.0

AWS Lambda is an excellent choice for serverless applications, automation, and microservices, but it has some cold start and execution limit challenges. It’s best suited for event-driven workloads, API backends, and real-time processing.

Pros

Lambda automatically scales up or down based on the number of incoming requests.

Cons

it has some limitations and challenges that can be frustrating, especially for large-scale or complex applications

### "Lambda is the golden standard of serverless functions"

June 18, 2024

5.0

Pros

Super easy to use and set up, you really don't need to know a lot to get your code running in the cloud, and the best part of it is that it will scale to very very large without anything on your side.

Cons

In large scales, you need to know a little about lambda in order to make sure your service runs without any disruptions.

Reason for choosing AWS Lambda

We chose serverless because of the cost benefits and also managing less infra. Within the serverless landscape, Lambda is the easy choice as it's much more mature than it's competitors in other clouds.

### "Powerful Serverless Task Executer"

March 11, 2026

5.0

Pros

Lambda do not require server provisioning, as AWS provides the infra needed, also Lambda scalability is great, the application can have few requests, or thousands per second and it would behave well. As pat of AWS environment, its integration with DynamoDB, S3 Bucket, Cloudwatch, etc is natural. As Lambda accepts multi code language, it gives teams more flexibility on building

Cons

Sometimes if the Lambda is "cold", I mean, not been run for while, it can bring some latency issues and times out.

### "Lightweight processing - good for initial phases of scaling"

January 17, 2023

3.0

It's really great to use from a developer perspective. It is a simple deployment process and maintaining dynamic loads to "kind of" match traffic demands. Do be careful of heavy applications, I find the cost grows the fastest with a lambda that has high memory demands more than increasing the number of lambda instances.

Pros

Using AWS lambdas provides an excellent win from the perspective of development velocity and removing the complexity around deployment and maintaining infrastructure. It allows developers to focus on the actual business logic of the services/processes instead of the tools being used. It should be noted, that this also reduces the number of places where things are likely to go wrong which is an underappreciated benefit.

Cons

This is quite expensive compared to a service/process you create and manage from the ground up. In the long run, you'll likely either find yourself moving away from using lambdas, or constantly redesigning your architecture to reduce the cost while servicing more throughput/complex logic. That is probably true for most software tools, but lambda processing costs can grow quite unexpectedly. Beware of memory demands - that can quickly add up and otherwise crash your lambdas (semi quietly) in the background.

### "AWS Lambda small pieces for big projects"

April 23, 2024

4.0

We have this service in several places. We put them as API endpoints, as gears to process data received from events with our defined thresholds in the service, as queue processors, and as B2B endpoints. Our experience with the service has been around how easy it was to define, develop, and create. So, it's a pretty straightforward implementation. You define the code and the triggers. Then connect it. Security is also a breeze with the IAM support.

Pros

The way that AWS Lambda can give you control of the way that it behaves and can be consumed is quite flexible. We were able to prepare for high-demand spikes on the services with hot availability, as well as connect them to be triggered by different events. This last part allowed them to be flexible for many patterns in our services as front and middle actuators in the flow of data.

Cons

This service is simple to use, so I can't recall a negative feeling associated with it.

Reason for choosing AWS Lambda

Most of our infrastructure was already based on AWS. To align with our billing strategies, it was easy to decide, given that the difference in costs with other alternatives was not a factor.

### "Most fast and scalable server-less service"

August 9, 2022

5.0

AWS Lambda allowed us to quickly upload pieces of reusable code for different projects in many languages without the need of including it to a framework. The service is capable of executing scripts at request, through the API Gateway without using any server, which reduces a lot the billing, making it almost free.

Pros

Every script uploaded into Lambda can be attached to an automatic trigger and an API Gateway endpoint. This could save a very important amount of memory usage for certains applications because the processing is made by AWS. It offers the convenient possibility of hosting your app in a Bitbucket or to upload it directly as a zip, saving a lot of time in complex deployments.

Cons

There are not cons regarding this service. It does what offers, a fast and very reliable server-less service that can execute scripts in parallel than your apps.

### "Excellent add-on for your integrations"

April 7, 2022

5.0

I use it for a variety of cases such as thumbnail generation, email notifications, url rewriting, websockets chat. It has always delivered and never had issues with uptime or capacity.

Pros

Easy to integrate with other AWS services through node.js or python code. This is my preferred way to extend services for adhoc customizations. With step-functions, one can go even further with chaining of functions.

Cons

Debugging, testing deployments and logs can be somewhat tedious.

Reason for choosing AWS Lambda

Ease of integration with other AWS services which can be leveraged to increase service reliability and costs.

### "Best and highly scalable serverless programming ecosystem in market "

March 30, 2022

5.0

it's a awesome thing to learn and use in daily life. I deploy lot of my applications using aws lambdas. It's fast and scalable and I love this experience.

Pros

Aws lambdas provides devloper a tool that can manage all there deployment and scalability. Coders can just focus on logic and codebase and aws lambdas take care of rest. It's auto scalable feature is super useful for dynamic traffic.

Cons

it's bit costly compared to normal ec2 machine tho we can minimise the cost with lambdas auto turn off when not in use feature. Other then this it's not easier to get directly hands, I found it bit trickier at first glance.

### "AWS Lambda: Simplifying Deployment with Automatic Scaling"

February 17, 2025

4.0

my experience while using AWS lambda is good as it offers a seamless way to deploy and manage code without worrying about server infrastructure. It is having great scalability and usage of features to use in our day-to-day activities.

Pros

It allows you to run code without provisioning or managing server.You have to pay for only compute time for which we have used the service.Many of the automations are possible by using lambda function

Cons

sometime the execution time and memory,may be limitations.Monitoring is little bit complicated at some extent.

### "The game changer AWS lambda "

December 27, 2024

4.0

My overall experience is fabulous 👌 AWS lambda is best suits for the organization looking to build agile, scalable and cost efficient application

Pros

First best thing about AWS lambda is that provide serverless architecture that means there is no need to manage server and architecture all these things are handle by AWS lambda

Cons

One bad thing about AWS lambda is that when you call or invoke the function first time or after period of time then its take too much time to execute.

### "An essential part of the JAM Stack Development experience"

January 19, 2022

4.0

If you're building JAM stack (javascript, apis, markdown) applications, you're eventually going to need to create your own API. Lambdas are an obvious choice when developing them. They act as the middle piece that holds your logic between an API Gateway and a multitude of storage/databases/other dynamic services.

Pros

It's hard to pick one feature of Lambdas that are the best since they really only have one feature: they are event driven functions that can accomplish pretty much any task that you as a developer are capable of writing. As long as you have a known input and an expected output, Lambdas allow you to do the necessary work to get you there. This setup works particularly well for creating custom APIs.

Cons

Our team has yet to find a really satisfying developer workflow. It's easy to iterate within the AWS console, but that means your code is not under version control. Once you go the version control route, you have to deal with the (self-imposed) complexity of your deployment processes. In short there feels like there's a sudden steep learning curve around best practices and code reuse, but this is a problem of many AWS services in general.

Reason for choosing AWS Lambda

AWS Lambdas are simple to use and are a staple of the the AWS ecosystem. Our organization has a contract to use Amazon services before other providers, so using Lambdas was basically a given.

### "AWS Lambda Review"

July 19, 2023

4.0

My overall experience with AWS Lambda is really very good. It saved me a lot of time since I do not need to write code, I can just use the interface to connect diifrent nodes.

Pros

The pricing of AWS Lambda is reasonable, and I like that I can activate and deactivate the service without deleting the project. Also, I like that I can use AWS Lambda in the AI project lifecycle to manage the pipeline and connect the model to up for deployment.

Cons

The documentations available for AWS Lambda on AWS are very limited and do not provide an implementation to an end-to-end project. Also, I do not like the limited control over the infrastructure as AWS Lambda does not allow me to control this point.

### "Feedback About AWS Lambda"

September 15, 2022

4.0

The overall experience with AWS Lambda has been good till now, the features that I like about i.e. The self reliant, and self scalable and money saving and easy to maintain. If I need trigger some jobs on event based, this is the most helpful thing and otherwise I will have to use the EC2 instance which is resource consuming and are good chances of being run idle.

Pros

The feature to self reliant is the best feature that I liked about the AWS Lambda. Currently we are using this for triggers to handle the events. It is working best as per the requirement of our business.

Cons

The deploying part of AWS Lambda is somewhat cumbersome and the testing it on dev server is something complex and it can be busy by just writing to the command and not using some JSON.

### "Server less capability to perform small batch jobs & deployment"

February 17, 2023

5.0

Using AWS lambda to run batch jobs or small independent jobs that can be scheduled is super easy. It can also take care of small deployments with simple stages.

Pros

AWS lambda is easy to use & it's highly compatible with almost all other AWS services, which makes it a clear winner in current general cloud platform. None of it's competitors come close to the mature level of this product.

Cons

It is a bit more costly than competition. Also compared to rising scalability of products like Google cloud functions, AWS lambda sometimes gets sidelined.

July 4, 2022

5.0

Pros

AWS Lambda is one of the most used services in AWS nowdays. The kind of work that does not require much computation and memory is very affordable to use on the AWS Lambda. The kind of ease it provides along with very high availablity and low latency is very much a sane choice for everyone.

Cons

There is not much I disklike earlier the time duration for lambda was less but now it is 15 minutes which is quite sufficient in my opinion.
