The Flip Side: AWS Can be Intimidating
AWS offers a huge ecosystem that places a lot of power in the hands of the users. They have access to a robust infrastructure that supports a wide range of applications and websites (including ecommerce stores and corporate portals). So, AWS hosting for eCommerce store is possible. The design of the AWS ecosystem is such that the users have a lot of latitude in pursuing their project’s objectives.
For this, Amazon ensures that its policies and AWS architecture management doesn’t get in the way of users. From the point where the users log into their account area to the day-to-day maintenance of their servers, AWS allows the users complete freedom to plan the use of the server as they see fit.
However, there is a not-so-small segment of AWS for beginners who prefer the power and robustness of the AWS infrastructure without the challenges of managing their servers AND their projects at the same time. This segment includes both the users who lack either the technical competency (and/or resources) or time to manage their AWS servers.
The challenges range from the server provisioning to the security and maintenance of the servers. Since AWS servers are pretty much barebones at the start, it takes some effort to setup the server and prepare it for the actual application that you have in mind. Once the server and the application are up and running, the user (or the sysadmin of the team) is mainly responsible for administration and security.
The Simple Solution of AWS for Beginners – Managed Hosting
This seemingly big problem of lack of time or expertise has a simple solution – managed Amazon hosting, which turns these barebones infrastructure by ensuring AWS for beginners a reality.
Fully-Managed Amazon Cloud Hosting
Fast, scalable hosting with proven AWS performance.

The managed hosting of AWS for beginners offers a simple way of creating and setting up the server. Usually, this happens through a simple one-page form that collects all the server specifications and then pass them along to the underlying processes for server provisioning. The process usually takes a few minutes and the server and the application is ready for the user.
Now depending upon the way the service delivery is structured, the user might not get to deal with the server directly. Instead, they interact with a feature-rich portal that offer a point-and-click interface for setting and managing their AWS server (and the deployed application).
The service offering continues as the managed hosting provider takes care of server maintenance. This involves offering the best mix of server level components that come together to provide a smooth and fast hosting experience to the users. This means offering the users choices for adding and removing cache subsystems, databases and related features.
