The ability to bring up servers and then do the computation and deposit means we don't have to maintain a data center. Everything is virtual and the security is also taken care of. It helps us to achieve compliance. Being a small startup with the security features that AWS provides helps us with compliance.

The most valuable features are the scalability options, low maintenance, and options to upgrade. AWS support is also pretty good. The generation upgrade is pretty simple and standardized.

My company uses the tool for cloud monitoring. We have a production, staging, deployment, and testing environment in AWS. However, we do not use the managed service of AWS yet. My team uses the required parameters for security like VPC, firewall, gates of security as well as the external layer of the app.

It's not the best of the best because we still have issues with downtime. We still have issues with the cost of storage, with all these different instance styles, and how much it costs. They cost an arm and a leg the higher you go.

In terms of improvement, they could build some client-side desktop tools that provide easier connectivity to Amazon.

Technical itself could be a bit more helpful, especially when it comes to integration assistance. When we talk to the technical team, often it's some issue with integration and they'll tell us to talk to the other company. Often, the other company will look at everything and not see an issue from their end and then we are at an impasse.

Support doesn't share or give insights on OS-based issues. That needs to improve because if someone is buying an EC2 instance with the Windows server and SQL license, the client expects that there will be a minimum level of support.

I think the whole AWS stack is very disconnected from each other. in the .NET space, everything just works nicely together. In the AWS stack, there is a lot of head scratching.
