Breaking Through The Cloud

Cloud computing is a revolutionary technology that is changing the way we interact with data and files, however, due to the fact that it is such a fresh technology, a lot of the terms and jargon involved can be quite hard to understand for those that may not have a huge amount of experience on the cloud. So, we’ve simplified the jargon in order to help even the least techy among us decipher exactly what cloud computing entails.

As a Service

Infrastructure as a Service (IaaS): This is the most basic form of cloud computing. IaaS includes computer processing, memory, storage and networking. Companies that make use of IaaS clouds are able to add storage or processing whenever they wish. They can also run whichever applications they want along with any operating system they require on their cloud service. IaaS differs to dedicated hosting however as it usually makes use of virtual machines that run across the service provider’s equipment, whereas dedicated hosting enables customers to rent a physical server in a remote data centre.

Platform as a Service (PaaS): This is the next step up from IaaS as it moves away from raw hardware and instead provides a business’ software developers with tools in order to create their own applications.

Software as a Service (SaaS): This pretty much does what it says on the tin as it involves renting software directly from a company via the cloud.

Virtual Machines and Types of Cloud

Virtual Machines: The essential building blocks of the cloud. Virtual machines are created by software that takes slices of computing power, memory and storage on real hardware and uses it to create more, smaller, flexible virtual computers. This process then allows information, data and devices to be shared from anywhere in the world with an internet connection. Businesses can therefore make use of virtual machines whenever they need to.

Private Clouds: This is infrastructure provided solely for a single organisation.

Community Clouds: This is a service for a group of businesses or a public sector organisation. This type of cloud can derive some of the economies of scale but also allows for a high level of security.

Hybrid Clouds: This can be useful in helping companies migrate to the cloud as IT loads can be moved from their own data centre to a third party during busy periods.

The above is by no means an exhaustive list as there are numerous other terms associated with cloud computing, for full details on the services provided please visit our product pages.
