AWS Lambda is a serverless architecture. So, you can use three languages like Java, Python, and Node. You can write your code in any language. The main use is if you have a team and your team has one Java developer, one Python developer, or one JavaScript developer. You all want to work together and in a single project, you can use multiple languages, by any of the users.

Robust platform, with useful features, and high scalability
Pros and Cons
- "AWS Lambda is itself serverless, and it is connected to the API gateway, and you can directly call the API through the API gateway and connect through AWS Lambda."
- "I would like to see the five zero four AWS Lambda invocation fixed. This is basically a time-out error."
What is our primary use case?
How has it helped my organization?
All of the features are very good and useful.
What is most valuable?
The most valuable feature for example Java needs a server, so you need to host your application somewhere. AWS Lambda is itself serverless, and it is connected to the API gateway, and you can directly call the API through the API gateway and connect through AWS Lambda.
What needs improvement?
I would like to see the five zero four AWS Lambda invocation fixed. This is basically a time-out error. Having consistency in this aspect will enhance how robust the solution is for us.

Learn what your peers think about AWS Lambda. Get advice and tips from experienced pros sharing their opinions. Updated: August 2025.
865,295 professionals have used our research since 2012.
For how long have I used the solution?
I have been working with AWS Lambda for the past two years.
What do I think about the stability of the solution?
The stability overall is good. As I mentioned before sometimes you get a couple of time-out errors that need to be fixed.
What do I think about the scalability of the solution?
It is highly scalable. You can use any of the features I mentioned, and you can write a number of functions in one project. We already use around twenty-five functions in one project.
How was the initial setup?
The initial setup is difficult. You need a lot of the code background. You should be at least five to ten years as an experienced developer.
What about the implementation team?
If it is a single deployment it will not take very much time. However, it does take more time as you increase code and volume.
What was our ROI?
The clients have seen a return on investment.
What's my experience with pricing, setup cost, and licensing?
The price is expensive and is based on usage. The more users you have the higher the cost.
What other advice do I have?
I would rate AWS Lambda an eight out of ten.
Which deployment model are you using for this solution?
Public Cloud
If public cloud, private cloud, or hybrid cloud, which cloud provider do you use?
Amazon Web Services (AWS)
Disclosure: My company does not have a business relationship with this vendor other than being a customer.

Beneficial mathematical templates, reliable, and high level support
Pros and Cons
- "The most valuable feature of AWS Lambda, from a conceptual point, is its functions. For example, it's mathematical templates into which you can write, and create your solution. You write small pieces of a solution under given parameters."
- "There are other similar solutions, such as Google Cloud Platform or Microsoft Azure. They might be better for small tasks."
What is our primary use case?
AWS Lambda is good because if you chop up your application into small pieces and that is something that can be accomplished as a Lambda-based solution on the cloud, you will save on the cost of your applications.
The reason Amazon AWS has provided AWS Lambda is to allow people to write small pieces of application tasks that will run on Amazon's own internal servers.
What is most valuable?
The most valuable feature of AWS Lambda, from a conceptual point, is its functions. For example, it's mathematical templates into which you can write, and create your solution. You write small pieces of a solution under given parameters.
For how long have I used the solution?
I have been using AWS Lambda for approximately two and a half years.
What do I think about the scalability of the solution?
Scalability is an in-house feature of AWS Lambda, it can scale well.
My team in the company is using this solution. I do not know how many other teams in the company might be using it.
We plan to use the solution in the future because there is always a use case for it.
I rate the scalability of AWS Lambda a ten out of ten.
How are customer service and support?
I rate the support from AWS Lambda a ten out of ten.
How would you rate customer service and support?
Positive
Which solution did I use previously and why did I switch?
We did not use another solution prior to AWS Lambda.
How was the initial setup?
The initial setup of AWS Lambda is easy, it can be done with a couple of clicks.
We use Amazon's CodeBuild, which does the deployment for us, and we use CodeDeploy to write our software application, which submits the code into our Git DevOps operation. From there it gets built and deployed automatically. It's similar to a CICD operation.
What was our ROI?
We have seen a return on investment using AWS Lambda. We don't have to pay for the solution, such as whatever logic that is implemented. If we had to build it ourselves as a microservice, we would be paying for the infrastructure.
Which other solutions did I evaluate?
There are other similar solutions, such as Google Cloud Platform or Microsoft Azure. They might be better for small tasks. Everyone can use the cloud providers' solution rather than building their own infrastructure. Any cloud provider has benefits.
What other advice do I have?
I would advise others to try the solution.
I rate AWS Lambda a nine out of ten.
Which deployment model are you using for this solution?
Public Cloud
If public cloud, private cloud, or hybrid cloud, which cloud provider do you use?
Amazon Web Services (AWS)

Easy integrations in a serverless format that has on-demand use and price models
Pros and Cons
- "The solution integrates well with API gateways and S3 events via its AWS ecosystem."
- "The solution should continue to streamline integrations with AWS services."
What is our primary use case?
My prior company used the solution to perform event-based actions and notifications, process data in an S3 bucket, and send messages in the SQS queue.
Our development team worked with 300 users across different departments to integrate the solution.
What is most valuable?
The serverless format is a benefit because on-demand computing can be performed without having to run machines.
The solution integrates well with API gateways and S3 events via its AWS ecosystem.
The solution works with various programming languages including .NET and Java.
What needs improvement?
The solution should continue to streamline integrations with AWS services.
At one point, there was an issue receiving support for a new version. Support was behind by two versions and this presented challenges, but they caught up over time.
For how long have I used the solution?
I have been using the solution for three years.
What do I think about the stability of the solution?
The solution is very stable.
What do I think about the scalability of the solution?
The solution is scalable for users because it is serverless. You can provision IAM users and easily give them access.
We scaled a core from one million to ten millions runs with no issues.
How are customer service and support?
I never needed to contact support.
How was the initial setup?
The setup is very easy and onboarding happens quickly.
What about the implementation team?
We implemented the solution in-house.
Implementation includes determining which APS you need, writing code, and packaging it all for upload. There is no real deployment other than adding the package to your CI/CD pipeline and pushing it. We do not consider this work to be substantial.
The operational push takes a matter of minutes.
What was our ROI?
The ROI is definitely worthwhile because pricing is based on use.
What's my experience with pricing, setup cost, and licensing?
The pricing is on-demand and based on runs or times that are billed out monthly.
For example, one million requests might cost 20 cents.
Which other solutions did I evaluate?
Our company wanted to compute in an ad-hoc manner. The solution allowed us to schedule cron jobs which made things easier.
The solution also integrates well with the AWS suite of products so can be used with an API gateway and S3 functions.
What other advice do I have?
The solution can be used for many scenarios encountered by IT developers. There is a general push to create serverless systems that have on-demand use and price models. For most use cases, there is a 50% chance the solution will be a good fit.
I rate the solution a nine out of ten.
Which deployment model are you using for this solution?
Private Cloud

A user-friendly event-driven, serverless computing platform that is easy to maintain
Pros and Cons
- "I like that it's easy to use and maintain. Lambda is good and supports different platforms, so you don't need to worry about language or maintenance."
- "The execution time could be better. One of the major limitations is the time period because it doesn't give you more than seven minutes. So, before thinking about Lambda, you should think through your use case and ensure it's a good fit. Otherwise, you can use batch, step functions, or other methods. Reports and the monitoring board could also be improved in terms of alerts. The threshold alerts are there but can be improved. It takes some time to get used to these methods and get the hang of them."
What is our primary use case?
We use AWS Lambda extensively for our maintenance work, for our products, and in our daily actions. We try to move some data based on alerts in certain situations and events. For example, if we are using queues based on the queue methods, we prefer to trigger different Lambdas for different functions (to enable some functionality across products). There are also a few Lambdas for audits. There are a few Lambdas for backups and many other use cases.
What is most valuable?
I like that it's easy to use and maintain. Lambda is good and supports different platforms, so you don't need to worry about language or maintenance.
What needs improvement?
The execution time could be better. One of the major limitations is the time period because it doesn't give you more than seven minutes. So, before thinking about Lambda, you should think through your use case and ensure it's a good fit. Otherwise, you can use batch, step functions, or other methods.
Reports and the monitoring board could also be improved in terms of alerts. The threshold alerts are there but can be improved. It takes some time to get used to these methods and get the hang of them.
For how long have I used the solution?
I have been using AWS Lambda for about five years.
What do I think about the stability of the solution?
AWS Lambda is pretty stable.
What do I think about the scalability of the solution?
AWS Lambda is scalable. There are some concurrency issues where threshold values play a role. We might end up making a request to increase those threshold values or the limit quota, but otherwise, it's pretty decent.
How are customer service and support?
AWS Lambda tech support is pretty decent.
On a scale from one to five, I would give AWS Lambda tech support a four.
How would you rate customer service and support?
Positive
How was the initial setup?
The initial setup is more about usage. Implementing this solution takes about 15 minutes, but the code and debugging will take some time. Two or three people can manage and maintain this solution.
On a scale from one to five, I would give the initial setup a five.
What's my experience with pricing, setup cost, and licensing?
AWS Lambda cost is pretty decent.
What other advice do I have?
I recommend this solution to new users as this tool simplifies mundane tasks and achieves a few things between the two systems.
On a scale from one to ten, I would give AWS Lambda an eight.

Easy to set up with good workflows but there are issues with some integrations
Pros and Cons
- "The initial setup is pretty easy."
- "I have seen some drawbacks with certain integrations."
What is our primary use case?
We primarily use the solution for integration purposes. We use it very closely with Jira, for example.
What is most valuable?
The workflow is the best thing about the product. When the integration happened and from where to where is something we can see automatically and navigate the workflow.
From Jira to AWS Lambda, we're sending data. When we go from Jira to AWS, through webhooks, we are sending data to the Lambda function. From Lambda, they're navigating Jira. Whenever the manual rework is done, they need to perform some job bundles from the AWS to the Jira only. They can operate from Jira to AWS and AWS to Jira, which is great.
The initial setup is pretty easy.
What needs improvement?
I don't have much experience after six months. I can't speak to the pros and cons.
I have seen some drawbacks with certain integrations.
For how long have I used the solution?
I started using the solution six months ago.
What do I think about the stability of the solution?
I'm not aware of any issues with stability. It's been issue-free so far.
What do I think about the scalability of the solution?
The solution can scale. We can add more users to it. We have ten to 15 people on the product right now. They are developers.
How are customer service and support?
I've never needed to reach out to technical support. I haven't had any issues. I can't, therefore, speak to how helpful or responsive they are.
How was the initial setup?
We found the setup to be straightforward. It's not complicated at all.
It took me one day to get everything up and running.
What's my experience with pricing, setup cost, and licensing?
I'm not aware of the exact pricing. I don't handle any licensing.
Which other solutions did I evaluate?
Our company is looking into ServiceNow to see how it handles integrations.
What other advice do I have?
We are a customer and end-user. We use the cloud for integration purposes.
I'm not completely into AWS Lambda just yet. What I can say, integration-wise, Lambda does not require any username or password from the Jira once they start talking to each other. It's integrated very well.
I'd recommend the solution to others.
I'd rate the solution seven out of ten. It is a very new tool for me; I need to do some more research on it to really understand it fully.
Which deployment model are you using for this solution?
Public Cloud
