What is a cloud infrastructure?

The term of cloud IT infrastructure, as popular as it has been in the recent years, is still a term surrounded by some mystery. In general understanding, it refers to the virtual infrastructure that can be delivered and accessed via the Internet. It is one of the most basic products delivered by cloud computing services through the IaaS (infrastructure as a service) model. Through the service, users can create their own IT infrastructure that is open to a configuration, just as a physical data center would. In most cases, cloud computing allows more flexibility in infrastructure design, which is highly beneficial to many companies and services. It can be easily set up, replaced or even deleted, contrary to the physical one which would require manual work. From the user standpoint, cloud computing allows for faster, better working systems that are less likely to freeze or malfunction as the cloud allows for the programs to be transferred from one server to another to remain accessible. Putting it in simple words, companies now have an IT infrastructure that they can use for their business purposes without having to pay for the construction of a physical infrastructure.

A cloud infrastructure includes a variety of virtual machines and components such as virtual servers, virtual PCs, virtual network switches, hubs and routers, virtual memory, and virtual storage clusters. All of these together create a one functional IT infrastructure that works just as well as a physical one would, with benefits such as lower costs, flexibility and scalability speaking on its behalf.

How do Amazon Web Services work?

Amazon Web Services (AWS) offers a wide range of global compute, storage, database, analytics, application and deployment services that altogether help organizations all over the world move faster, with lower IT costs and scalable applications. Just as most cloud IT services, AWS works on the pay-as-you-go pricing system, which means that companies no longer need to pay for unused IT infrastructure – they use the virtual servers to their needs and pay for what they’ve used – never more, never less. AWS provides a simple way to create a complete IT infrastructure for your company, without the worry of physical computers and servers being corrupted and in turn stopping the business entirely. A Cloud services platform such as AWS  obviously owns and maintains the network-connected hardware required for the cloud to work, but from their clients’ point of view, the infrastructure is entirely virtual.
