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.

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."

Does not need server configuration and can be used for short-term automation processes
Pros and Cons
- "Because AWS Lambda is serverless, server configuration is not required, and we can run it directly anywhere."
- "If it is a specific ETL process or a long-term one, then AWS Lambda is not a good option."
What is our primary use case?
The primary use case is processing data. We use the pipeline multiple places to process the data. Whatever JSON files we get, we have to standardize, enrich, and also format to the application.
What is most valuable?
The most valuable feature is that it's serverless. Therefore, server configuration is not required, and we can run it directly anywhere. We can write Java code or Python code in that.
The initial setup is straightforward as well.
AWS Lambda is good for short-term automation processes.
What needs improvement?
If you want to run processing data, which takes less than 15 minutes, then you can use Lambda. However, if it is a specific ETL process or a long-term one, then AWS Lambda is not a good option.
The longer Lambda runs, the higher is the cost incurred because the cost is based on runtime.
At times, it hard to know when Lambda should be used and when it should not. So in the future, if there are serverless extensions, it would be fine.
For how long have I used the solution?
I've been working with AWS Lambda for six to seven months.
How was the initial setup?
The initial setup of AWS Lambda is straightforward.
What's my experience with pricing, setup cost, and licensing?
The cost of AWS Lambda is based on runtime.
What other advice do I have?
It's a good product, and we use Lambda for short run processes, for example, processing a file from the landing zone. Suppose FTP or SFTP has put a file in one landing area, and we have to push a file to the S3 bucket. We would not need to do any writing, shell scripting, or Linux coding, etc. In general, with Lambda you can get the Python coder or Java code.
So, professionals can easily perform these tasks within a short time. This will help with agile processes and sprints. My advice is that AWS Lambda is a good service for short-term automation processes.
I would rate AWS Lambda at eight on a scale from one to ten.
