Serverless compute server used for data processing type transformations from one source to a target
Pros and Cons
- "Lambda has improved our organization by making it possible to transform data."
- "Lambda has limitations on the amount of memory you can use and is not a good solution for long running processes."
What is our primary use case?
There a variety of use cases for this solution but it is mostly used for data processing type transformations from one source to a target. In instances when Lambda works well, we are planning to increase usage.
Deployment and maintenance of Lambda requires two people but this may increase depending on the size of the deployment.
How has it helped my organization?
Lambda has improved our organization by making it possible to transform data.
What needs improvement?
Lambda has limitations on the amount of memory you can use and is not a good solution for long running processes. If the amount of data is reasonably small, it will run and transform successfully. If you have tons of data coming in, it stops working and you have to restart it.
The orchestration and coordination between different Lambdas could also be improved.
For how long have I used the solution?
I have used this solution or a couple of years.
What do I think about the stability of the solution?
This is a fairly stable solution.
What do I think about the scalability of the solution?
This solution has some limitations on scalability due to the problem with coordination between the different Lambdas. Is it not very straightforward and you have to do a lot of testing.
How was the initial setup?
The initial setup was fairly straightforward.
What other advice do I have?
I would advise others to use it in those circumstances where it works well and to be aware of the problems with coordination and orchestration. Make sure that it doesn't have to process tons of data.
I would rate this solution a seven out of ten.

How was the initial setup?
The solution is serverless computing so there is no setup. You just launch the service, write your code, and run it.
What's my experience with pricing, setup cost, and licensing?
The solution is part of the AWS subscription model that is paid annually. There is no charge for monthly usage.
There are many calculation criteria for AWS services or licenses. It is difficult to say whether the solution reasonably priced or expensive. Each company weighs price against the benefits and efficiencies provided by the solution.
Which other solutions did I evaluate?
AWS is the pioneer of cloud computing and they lead the industry in innovations. Other providers follow in AWS' footsteps to implement similar features and service levels.
AWS has differentiated the use cases for serverless computing. Lambda is used for basic capabilities like triggered events and Fargate is used for extended capabilities.
I started using Lambda for a specific use case and I continue to use Lambda and Fargate for use cases as recommended by AWS.
What other advice do I have?
I definitely recommend the solution and rate it a ten out of ten.

An inexpensive tool that's feature-rich, stable, and supports different languages
Pros and Cons
- "What I like best about AWS Lambda is that it's feature-rich, and I appreciate that. I also like that it's stable and supports many languages."
- "What could be improved in AWS Lambda is a tricky question because I base the area for improvement on a specific matrix, for example, latency, so I'm still determining if I can be the judge on that. However, room for improvement could be when you're using AWS Lambda as a backend, it can be challenging to use it for monitoring. Monitoring is critical in development, and I don't have much expertise in the area, but you can use other services such as Xray. I found that monitoring on AWS Lambda is a challenge. The tool needs better monitoring. Another area for improvement in AWS Lambda is the cold start, where it takes some time to invoke a function the first time, but after that, invoking it becomes swift. Still, there's room for improvement in that AWS Lambda process. In the next release of AWS Lambda, I'd like AWS to improve monitoring so that I can monitor codes better."
What is our primary use case?
AWS Lambda is mainly used for automation. To simplify, in AWS Lambda, I define a function, and I can invoke that function or feature whenever I want and on schedule.
For example, if I have data to collect daily from different services, I schedule the AWS Lambda function to do that, and it does the job. That's one of the use cases of the tool.
Another use case for AWS Lambda is when you have multiple servers running and need to shut down the servers at night. You can configure an AWS Lambda function that would shut down the servers every night on schedule. You can also use it as a backend and invoke it through API, so you deploy your backend from an AWS Lambda function, then link it with the API gateway, then you can invoke your function through the API.
What is most valuable?
What I like best about AWS Lambda is that it's feature-rich, and I appreciate that. I also like that it's stable and supports many languages.
What needs improvement?
What could be improved in AWS Lambda is a tricky question because I base the area for improvement on a specific matrix, for example, latency, so I'm still determining if I can be the judge on that.

In the next release of AWS Lambda, I'd like AWS to improve monitoring so that I can monitor codes better.
For how long have I used the solution?
I've been using AWS Lambda for one year and a half.
What do I think about the stability of the solution?
AWS Lambda is a stable product.
How are customer service and support?
I have yet to contact the AWS Lambda technical support team because I haven't experienced any difficulty with the tool.
Which solution did I use previously and why did I switch?
One of the reasons my company went with AWS Lambda is that it's serverless, so you don't need to manage any server because AWS will handle it. This means that a lot of responsibilities will be taken care of by AWS, which helps you avoid many problems.
Another reason for choosing AWS Lambda is its stability. Latency is also not a problem on AWS Lambda, allowing you to use different services in your AWS account securely. For example, when you want to reach the AWS billing service, you can do it within the environment of your AWS account without an external tool, which makes it very secure. AWS Lambda also helps you reach other AWS accounts securely because it depends on roles rather than search keys or passwords.
How was the initial setup?
The initial setup for AWS Lambda is straightforward. It's effortless to start using AWS Lambda.
What's my experience with pricing, setup cost, and licensing?
Price-wise, AWS Lambda is very cheap. It's not free, but it's not that expensive.
What other advice do I have?
I'm using the latest version of AWS Lambda because when a framework or tool is deployed on a public cloud, it's always the newest version, and you don't get to choose the version.
I'd tell first-time users of AWS Lambda, or anyone looking into using the tool, that you can deploy every application within AWS Lambda, and it's very easy to set up and deploy. You can also use it with any application regardless of language because AWS Lambda supports many languages such as Go, Bison, Node, GS, and .NET. The tool is very code-agnostic, and not coded with programming languages, so you can still use Docker images to start your AWS Lambda function, for example.
My rating for AWS Lambda is nine out of ten because of how hard AWS worked on having good latency, security, and an intuitive start. The tool supports different languages and is stable, so I gave it a high rating.
I'm a customer of AWS Lambda.

Can be easily deployed and is stable, scalable, and usage-based
Pros and Cons
- "I like the pay-for-what-you-use feature. This is the main reason why we use AWS Lambda. I don't have to manage servers; I just have to configure Lambda and expose it to an API gateway."
- "Another challenge I've noticed is that there is a limit to the environment variables such as the 4 KB limit. Although, the advice is to use parameters or other things to store the details when the limit has exceeded the data, this adds additional intensity to the application. If the size limits for environment variables can be revealed, it would be helpful. Even if we have to pay for it, at least we would know that we are not dealing with latency. So, I would like to see the size of the environment variables increased."
What is our primary use case?
We use AWS Lambda for jobs that we just want to offload to a cloud function. We are an educational institution, and if I want to upload an exam I generated for all my students, then I just write the script on AWS Lambda. That is, we use it for independent jobs that we can offload on their own.
What is most valuable?
I like the pay-for-what-you-use feature. This is the main reason why we use AWS Lambda. I don't have to manage servers; I just have to configure Lambda and expose it to an API gateway.
What needs improvement?
AWS Lambda's cold start needs to be improved. It has to warm up first, and so, the response time is slower.

What do I think about the stability of the solution?
It's very stable.
What do I think about the scalability of the solution?
AWS Lambda is scalable; I don't need to worry about it. At present, we have less than 10 people using this solution.
How was the initial setup?
The initial setup is straightforward. It can be done on the console, and you can use the infrastructure as the code.
The deployment time can vary from 10 minutes to an hour depending on your needs and how comfortable you are with AWS Lambda.
What other advice do I have?
AWS Lambda now supports multiple languages, but find out if the language you want to use to write your jobs is supported by it. If it is supported, then you are good to go.
Because AWS Lambda is scalable and does what it's meant to do, I would rate it at nine on a scale from one to ten.
