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 Director Information Technology and Services Used the software for: 2+ years ### "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. 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. 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 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 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. Switched from [Heroku](https://www.capterra.com/p/158191/Heroku/) The bandwidth speed and the server availability. Followed by the wide community. Review Source AB Ashveen B. 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 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 SM Sahil M. Software developer Information Technology and Services Used the software for: 6-12 months ### "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. Review Source VR Verified Reviewer Senior Data Architect Information Technology and Services Used the software for: 2+ years ### "Power of Serverless processing AWS Lambda" May 19, 2024 5.0 Very good. Implemented a serverless data lake using event driven approach for AWS lambda. Very cool and highly recommended. Pros Easy, simple and powerful for data processing. Highly integrated with different AWS services. Very powerful for event driven architecture. Cons AWS lambda timeout is 15 mins. For long running process AWS lambda is not suitable. Review Source VR Verified Reviewer AWS IoT Developer Computer Software Used the software for: 1-2 years ### "Easy to get started, gets complicated quickly!" May 26, 2021 4.0 Lambda is one of the best services provided by amazon web services. I have been using this service for the past couple of years. You can use this service from running smaller scripts to deploying a website that can be served to thousands of users concurrently. It supports multiple languages, a developer can pick a language of his choice, plays a major role in deploying a microservice architecture in no time. Best practices specified in the documentation have to be followed diligently to avoid encountering common issues. Pricing wise it is very economical and will not burn your pockets compared to other AWS services. Pros It is easy to get started, within a couple of steps you will be able to run a highly scalable solution with API gateway and lambda. It is good for running small scripts that can complete within 15 minutes. Their documentation for this service is comprehensive, provides good examples for the developers. It is completely serverless, no extra effort needed to manage servers. Cons It gets complicated very quickly if you are using it for complex tasks like stream processing. There are some performance issues that you might encounter due to cold starts, hence keeping lambda warm is very essential. Debugging the issues through cloudwatch logs in a time-based manner can get challenging if your lambda is getting invoked multiple times in a short duration. The maximum code runtime is for 15 minutes and after that, your lambda will get timed out, so if your code has a runtime of greater than 15 minutes, you need to move to other AWS solutions like ECS fargate.

Pros Its serverless, servers are not running up all the time, they run only when triggered.Its cheap, you need to pay only for what you have used.Its fastest, it does the computing a way faster than the other virtual servers.Its easy to use with lots of Integration plugins available. Cons The only con is number of concurrent runs is very less i.e. under 1000.For heavy applications we need more number of concurrent runs. Review Source VR Verified Reviewer Senior software engineer Banking Used the software for: 2+ years ### "AWS Lambda is a cheap and very useful" April 13, 2022 5.0 We are using it as part of a streaming pipeline and also as a web api for downstream systems. It it working really well, except when there are cold starts, which can cause delay in the processing or timeouts on the serving layer Pros budget friendly for small to medium workload easy to deploy using AWS CDK or terraform. supports multiple runtimes for different programming languages provides monitoring and logging out of the box. Cons cold starts can be too slow if your architecture is time sensitive. It can get expensive for very high number of invocations. Review Source VR Verified Reviewer Assistant Consultant Information Technology and Services Used the software for: 1-2 years ### "AWS Lambda - Flexible Compute Option" March 15, 2022 5.0 AWS Lambda is great tool which serves various purposes on team. I have been using AWS Lambda for more than a year to process and upload data to AWS. It reduces the headache of maintenance and scalability which helps with the development. Being a serverless framework, it is easy to develop and test in local. It is being widely used in our account by different teams for devops. Pros Diverse support to runtime languages, Seamless integration with other AWS services, Heavily scalable, Execute small tasks quickly, Create functions and automate processes. Cons Not cost effective as every call to a function will be charged. Limited plugins and execution time.

CTO Computer Software Used the software for: 2+ years ### "AWS Lambda is unmatched platform for building instantly scalable apps" March 24, 2022 5.0 Pros AWS Lambda has created a simplified services model. It’s unique with its own set of features and APIs. AWS makes it extremely simple to either use Lambda independently or build a custom cloud. From data extraction, storage and visualization, AWS provides all in-one service for app deployment with Lambda. Cons AWS’s docs at times are quite complex in terms of structure. It would be nice to see simplified docs that focus more on combining different pieces of cloud services to build an app. They have visual solutions designer but that doesn’t help with implantation of a prototype service. Lambda functions are relatively easy to use but they lack guidance on building serverless app. Review Source kS krishna S. software developer Information Technology and Services Used the software for: 1-2 years ### "my experience with lambda" September 16, 2022 4.0 overall experience with AWS lambda is good it is best suited for running a script without a server and monitoring is also provided which helps to keep things in check. it is cost efficient Can handle a higher number of requests and triggers integration with other services simply. Pros AWS Lambda can be used to run scripts and code from multiple programming languages like Java, Go, PowerShell, Python, and others. it is a server-less compute service that will run your code when required you can customize it according to the use case like memory which will affect the performance of the function best used when you want to test a script or run the scripts with less dependency and the server is not required which will save the cost . Cons you have to set up an environment that is complex, setting up cronjobs is difficult editing is difficult you have to upload a file every time, memory, and time limit.

Pros Eliminates concerns about OS, dependencies, etc. It is really great to have a scalable solution without paying for a fixed price. Also triggers like API, Queue,Scheduling is very helpful for different cases. Cons Bundle size and cold start times may be limiting for big projects. Also DB connection management can be a problem for concurrent runs.

CEO Computer Software Used the software for: 2+ years ### "Serverless computing is awesome! Especially if you don't want the hassle of managing VMs" June 10, 2021 5.0 We've created several products that are totally serverless (Lambda + DynamoDB) and we're very glad we don't have to handle servers at any level! Pros Lambda is as simple as writing a piece of code that you want to run and... that's it! Yes, you'll have to do some wiring using API Gateway or other triggers for Lambda, depending on your use case - but the fact that you don't have to manage servers is a game changer in terms of maintenance, deployment, etc. Cons With this new methodology comes a new mindset. Sure - it's serverless, but you should keep in mind that if things like RAM and concurrency are still something you should handle. Also, there is a point where using VMs may have lower TCO (especially if you can use spot instances) - but don't forget to add the salaries and attitude of devops to the equation.
