The cloud services are everywhere. Many companies operating in the wide IT industry are moving their businesses to virtual servers, reducing their overall expenses and saving on the hardware needs. The flexibility, accessibility and cost-saving benefits of the cloud have been a point of heated discussions for many years now and it seems like major companies see nothing wrong with the general tendency of moving from physical to virtual servers. But how reliable is the cloud IT infrastructure in reality and how does it reflect in the growing popularity of Amazon Web Services?
Cloud IT infrastructure – what is it?
In general terms, the cloud IT infrastructure refers to the virtual products delivered by cloud computing services through the IaaS (infrastructure as a service) model. Using the cloud, clients can create their own IT infrastructure that is open to any configuration, just as a physical data center would, the difference being that 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 at all times. Companies that have been working on physical servers now have an IT infrastructure that they can use for their business purposes without having to pay for the maintenance of a physical infrastructure on their premises.
It’s always a good idea to contact one of the AWS Partners!
In a basic understanding of the topic, cloud infrastructure consists of virtual machines and components such as servers, PCs, network switches, hubs, routers, memory, and virtual storage clusters which together create a 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.
Amazon Web Services
Amazon Web Services (AWS) is a service that offers a wide range of global compute, storage, database, analytics, application and deployment to companies all over the world. Just as most cloud IT services, AWS works as a pay-as-you-go pricing system, which means that businesses are paying only for the data, transfer, and storage they have used in a particular month. AWS provides a simple and easily understandable way to create a complete IT infrastructure for any company. A Cloud services platform such as AWS is obviously owned by a company that maintains the network-connected hardware required for the cloud to work, but from their clients’ point of view, the infrastructure is entirely virtual.
