The Key Management Service (KMS) feature is very helpful for security. It encrypts the data that is being saved. Cloud storage is also very helpful, and it could be AWS S3, which a lot of people use.

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 feature is EC2 is scalable, so when you want to move to market, you don't need to wait until your provision is fast, you can just go and provision it and then easily install your application.

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.

Regarding availability, a noticeable improvement would be the possibility of more load balancing configurations and the deployment of more datacenters, mainly in Latin America.

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.

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.

They should fix the key pair name functionality and provide the ability to assign multiple key pair names to an EC2 instance. It is a key pair feature, and it provides you the ability to actually log into the server. It is basically like a password. In terms of new features, it should have the ability to increase and decrease the instance size based on certain times of the day. We should be able to do this without turning off the EC2 instance. Currently, you have to turn it off and then turn it back on. It should also have HTTPS or SSL integration.

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