We considered deploying our functions in EC2 with Auto Scaling but decided on Lambda as we need a lightweight function that is able to scale up and down quickly. Also, the overall cost is much lower.

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.

Our company is looking into ServiceNow to see how it handles integrations. 

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. 

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. 

We didn't evaluate other options because it was a requirement for the project.

To the best of my knowledge, we have been using the solution from the get go. 

The vendors on the shortlist now would be Cohesity, Commvault, Druva. But in the past, I went with this because we were using an AWS cluster anyway. It was easy-ish.
