This material covers the initial set up of an entire Cloud environment at Amazon Cloud infrastructure to run any web implementation solutions. This is the quickest answer that you may find out there, so let’s stat it!
We will cover all the steps to set up an entire environment in a cloud platform, from creating an user account at Amazon Web Services to creating and customizing Virtual machines (AMI), Virtual Storage Units, Virtual backups, Elastic IP’s, etc.
For all of you that don’t understand some of the acronyms used here, let’s just to look at them before to start:

Basically, moving to the cloud it shouldn’t impact your architecture with many changes as we believe. If your platform has a well design architecture based on independent layers (UI, Logic, Data, etc), adapting to work in a Cloud environment only mean to add a new layer of virtual environments to your n-tiers environment. Moving to the Cloud only become a problem when solutions don’t have a solid and well designed architecture and basically they are pushed back at the moment to adapt to this new age of technology.

I have talked about virtualization and also about Cloud Computing but, what options are available to implement cloud computing Infrastructure implementations? Well, that is simple!
Hardware technologies for virtualization (hypervisor)
Hypervisor Virtualization has a layer (usually a thin Linux kernel shown here as a hypervisor or standard OS) that is loaded directly on the bare server. To allocate hardware and resources to the virtual machines (VMs), all hardware on the server must be virtualized. The next layer up shows each chip, board, etc. that must be virtualized so that it can be assigned to the VMs. Once in the VM itself, there is a complete copy of an operating system and finally the application or workload.

Cloud computing can describe services being provided at any of the traditional layers from hardware to application. In practice, cloud service providers tend to offer services that can be grouped into three categories: Software as a Service, Platform as a Service, and Infrastructure as a Service. These categories group together the various layers, with some overlap.
Software as a service (SAAS)
Software as a Service features a complete application offered as a service on demand. A single instance of the software runs on the cloud and services multiple end users or client organizations.

Everyone has an opinion on what is cloud computing. It can be the ability to rent a server or a thousand servers and run a geophysical modeling application on the most powerful systems available anywhere. It can be the ability to rent a virtual server, load software on it, turn it on and off at will, or clone it ten times to meet a sudden workload demand. It can be storing and securing immense amounts of data that is accessible only by authorized applications and users. It can be supported by a cloud provider that sets up a platform that includes the OS, Apache, a MySQL database, Perl, Python, and PHP with the ability to scale automatically in response to changing workloads.

Virtual servers in the cloud model. Basically they are providing Infrastructure as a Service. If you need to run your application, you can go to their site, configure your own server with your required configuration and software libraries and they will generate a server on the fly for you! Basically all this magic has come about thanks to virtualization technologies which allow you to create software servers independent of the hardware infrastructure running them. These VMs can be scaled and migrated depending on the need.
