Solution Architect Information Technology and Services Used the software for: 1-2 years ### "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 Review Source VR Verified Reviewer Interactive Experiences Architect Computer Software Used the software for: 2+ years ### "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. Alternatives considered [Microsoft Azure](https://www.capterra.com/p/16365/Azure/) 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. Review Source Andy Q. Software Developer Automotive Used the software for: 2+ years ### "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.

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. Review Source FM Fidel M. Software Engineer Information Technology and Services Used the software for: 1-2 years ### "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.

IT Director Non-Profit Organization Management Used the software for: 2+ years ### "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. Switched from [Pipedream](https://www.capterra.com/p/242217/Pipedream/)[IFTTT](https://www.capterra.com/p/186695/IFTTT/) AWS Lambda Pricing and performance were preferred. Integration with other AWS services opens more possibilities. Review Source AJ Abhinav J. Developer Information Technology and Services Used the software for: 1-2 years ### "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.

A real eye opener for serverless architecture Cons Nothing that can be seen as a negative.. however an optimal solution for cold starts can be arrived with no extra cost.. Alternatives considered [Microsoft Azure](https://www.capterra.com/p/16365/Azure/) Reason for choosing AWS Lambda While our dependency was on a higher architectural advantage for aws over azure, this switch from azure functions to aws lambda an inclusive transition Review Source GG Gavin G. Digital Project Manager Information Technology and Services Used the software for: 2+ years ### "Serveless architecture that works" November 11, 2021 5.0 Pros In an attempt to move to newer serveless technology we decided to go with AWS. With the use of AWS Lambda, triggers and API Gateway we can create dynamic, powerful, database driven websites that don't require hosting, pay for what our customers use, completely scalable, secure and reliable. Cons It can take a while to get used to serverless architectures, primarily the idea of it being stateless. API gateway can also be complex to get right, but it's absolutely worth it. Alternatives considered [Microsoft Azure](https://www.capterra.com/p/16365/Azure/)[Google Cloud](https://www.capterra.com/p/268690/Google-Cloud-Platform/) Reason for choosing AWS Lambda AWS ticked more boxes than the other options. Review Source FM Flavio M. Senior QA Analyst Banking Used the software for: 2+ years ### "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. Review Source AP Ankush P. Cosultant Information Technology and Services Used the software for: 2+ years ### "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. Review Source VR Verified Reviewer Sw. developer Information Technology and Services Used the software for: 2+ years ### "Great, but needs a different mindser" April 4, 2022 4.0 Overall I have had a great experience with AWS Lambda, it is a very powerful tool and it has a lot of potential. I would definitely recommend giving it a try if you are looking for an easy way to run small pieces of code in the cloud. Pros I think the biggest pro of AWS lambda itself is that is an AWS service, this makes integrating other AWS services straightforward, SQS, SNS, Dynamodb, Appsync, APIGateway, IAM, to name a few, are some of the services I had a really pleasant experience to integrate with. Another Pro I would say is the ease of development, you can write your code in either Java, Node.js, Python or Go and deploy it easily using CDK or Serverless framework. The pricing is also very attractive, you are only charged for the time your code is running and the amount of memory you use although its a little bit pricey compared to other solutions like firebase functions or cloudfare workers. Cons The biggest cons I have noticed when using lambdas are: - Cold starts: when your function is not already running in memory and needs to be spun up, this can take a few seconds and during this time your function is not available, really discouraging the development of lambda functions in JVM languages or others that have a big runtime - Observability: while it's true that you have logs out of the box in AWS Cloudwatch/CloudTrail and Xray metrics, observability is not the greatest, for instance log text search is not something you get. Usually this is solved by adding another provider like ELK stack or Lumigo. - Vendor lock-in(if applies) : Taking advantage of all the benefits of running functions on AWS may not be the greatest idea when you care about vendor lock-in and you are looking for a cloud agnostic solution this would have an impact also in pricing as AWS is not the cheapest cloud provider. Review Source DP Darian P. Team Lead of Internal Tools Insurance Used the software for: 2+ years ### "Review for AWS Lambda" July 7, 2021 5.0 Lambda allowed us to keep our code contained and efficient. We moved from running all our API code on a single "project" hosted on a server, to running many small codebases which targeted specific functionality. The change in mindset I believe was helpful in making sure that each new endpoint we build is as fast as it could be. Pros We like how Lambda is able to be deployed and updated quickly. It allows us to spend less time worrying about server loads or accessibility knowing that it is on the cloud and reliable. Also the benefits of being ingrained in the AWS infrastructure is helpful with connecting to our other services. Cons I think the console aspects of the software could use improvements. Here are some examples: 1. The testing UI is basic. You can create test cases, but in doing so you can't even view the codebase unless you click off. I would like to be able to look at both at the same time. 2. The code editor could use some enhanced functionality of popular editors like VSCode or even google docs. Specifically, one thing I noticed is I cant do CTRL+} with several lines highlighted to tab all lines over. 3. Lambda Layers are helpful but I would like to be able to view the code inline somehow rather than just see the version of the layer i am using. It would make it easier to differentiate when your lambda layer has several dozen versions, which version I am using or need. Reason for choosing AWS Lambda We previously had a self hosted server with a pyramid python REST API. We have migrated most of our endpoints to be hosted through lambda in order to start moving all our services to cloud based. We wanted a solution that was reliable, cloud based, fairly inexpensive. Being a part of AWS which we already used for several projects also drew us in.

Pros Most liked about this software is it's API integration with connectivity to database to store the important data. Cons Lease like is built in fault talaurance feature. Review Source OI Omer I. Software Engineer Information Technology and Services Used the software for: 2+ years ### "AWS Lambda is a powerful elastic compute capacity" August 10, 2022 5.0 Easy to set up, test, and deploy but need to be managed correctly to avoid security riks. Pros We have easily deployed AWS Lambda for various use cases and through different deployment options. It integrates well with AWS services allowing you to keep your coding and DevOps guidelines even when deploying serverless apps. The Pay-as-you-go pricing model makes it ideal for small projects or relatively small tasks that you want to execute after pre-defined events or API calls. Cons Since Lambda integrates well with AWS resources, it can be a source of security vulnerabilities in the case of an incorrect Identity and Access Management (IAM) setup. This issue is not a weakness of Lambda, but Engineers need to be cautious when setting up IAM Users and Roles to avoid this risk.

Pros Event driven, support most widely used programming languages, no cost when functions not running, zero administration effort, highly scalable and available Cons There are limits on the runtime environment (disk space, deployment package, memory) that is auto provisioned. Also execution time for any function cannot be more than 15mins.

There are multiple Lambdas running in our tech stack and architecture, connecting one service to another. Scalability and reliability are perfect. Cons Even though it's serverless, you still are required to update software for example when support for an older Node version is dropped. So you still have maintenance.

Certain condition. For us giving summation email acknowledgment or trigger a new log make us very happy Pros Rather than says no it as a software, I would say it’s a function. I can use this without using any dedicated or shared compute resource. It’s very fast and need very less resource to run. Cons You need to know how to use and the way how effectively you can use it else this may come a huge billing Review Source VR Verified Reviewer Developer Information Technology and Services Used the software for: 1-2 years ### "One of the best serverless computing services" December 17, 2022 4.0 Pros AWS Lambda is a great service offering from AWS. What I like the most is the fact that it is serverless and it allows you to write computing logic in multiple programming languages, also has the option to automate the computation. Cons Even though AWS Lambda is great and has great features but the online IDE is not that great and allows very limited customization. For more complex tasks we need to write our logic offline as a AWS SAML project and then deploy it to AWS. It would be great if we could install any custom package inside the online IDE itself and write more complex logic.

Pros There isn't much you can't do with lambda once you know how to trigger and edit the scripts within. If you are familiar with python (this is what we use) then this isn't too steep of a learning curve. You are even able to front websites with lambda saving a lot of money. Cons The thing I would say I like least about lambda is if you have a long running job there might be some hoops you have to jump through. But every few months the execution time is getting longer and longer. Review Source GV George V. Founder Computer Software Used the software for: 1-2 years ### "Very efficient and easy to use" November 21, 2023 5.0 Pros Very low cost to execute functions and they have largely solved the cold start issues Cons Lambda is fantastic, cannot fault it.
