Amazon Web Services (abbreviated AWS) is a collection of remote computing services (also called web services) that together make up a cloud computing platform, offered over the Internet by Amazon.com. The most central and well-known of these services are Amazon EC2 and Amazon S3.

As a Consulting, Reseller, and Government partner of AWS, A&T Systems has experts who design, deploy, optimize, monitor and manage applications, servers and storage for our government and commercial customers in the AWS cloud.



Here are some frequently asked questions and answers:

What is Cloud Computing?

Whether you are running applications that share photos or support the critical operations of your business, you need rapid access to flexible and low cost IT resources. The term “cloud computing” refers to the on-demand delivery of IT resources via the Internet with pay-as-you-go pricing.

Where do savings come from?

Cloud Computing helps you reduce your overall IT costs in multiple ways:

  • No Upfront Costs: Building on-premises infrastructure can be slow and expensive. There is expensive hardware that needs to be ordered, paid for, installed and configured – and all of this needs to happen long before you actually need it. With Cloud Computing, you don’t have to spend time on these activities; instead you just pay for the resources you consume on a variable basis.
  • Low Ongoing Cost from economies of scale: Massive economies of scale and efficiency improvements allow cloud providers to continually lower prices.
  • No Need to Pay for Excess Capacity: You pay for what you actually use and not to pay for the excess capacity that you do not use. With your own datacenter you need to have capacity for today, but also for near-term, occasional and cyclic growth needs.

How do I migrate large amount of data from my datacenter to AWS Cloud?

If your application uses large amount of data, migrating this data to the AWS cloud and completing a smooth cutover can be a tricky and difficult task. In most situations, an application must keep running until certain deadline, and then be ready to start in the new environment after a short window of time.

Within such a tight migration window of time, the data must be transferred to the Cloud environment, properly configured, tested and systems back to operation. A&T Systems has developed a special methodology, we call AWSDirect, using a very elastic high speed direct connection to the AWS cloud using dark fiber. With AWSDirect, we have successfully migrated applications with multiple terabytes of data in short time windows.

How can cloud computing help me scale up or down with my business needs?

Predicting how you are going to adopt your new application is difficult, and it’s hard to get right. So, when you make a capacity decision prior to deploying an application, you often either end up sitting on expensive idle resources or dealing with limited capacity. If you run out of capacity then you are faced with a poor customer experience until you can acquire more resources. With Cloud Computing, these problems go away. You provision the amount of resources you need. If you need more, you can easily scale up. If you don’t need them, just turn them off and stop paying.

Can cloud computing help me go to market faster?

With traditional infrastructure, it can take weeks to get a server procured, delivered, and running. These long timelines stifle innovation. With Cloud Computing, you can provision resources as you need them. You can deploy hundreds or even thousands of servers in minutes, without talking to anyone. This self-service environment changes how quickly you can develop and deploy applications and allows your team to experiment more quickly and more frequently.

Do I need a cloud specialist firm to help me migrate to cloud?

AWS Consulting Partners are professional services firms that help customers design, architect, migrate, or build new applications, and manage their new environment. To do it right, you may want to recruit the help of these specialists.
