Archiving - The systematic approach to saving and protecting all data contained in emails or instant messages so that it can be easily accessed at a later date; archiving tools integrate with email or instant message providers to accumulate and index data such that it is searchable and quickly retrievable by the user.
Big Data - massive data sets which get so big they become difficult to work with in traditional ways. What is considered Big Data varies between organisations depending on their size and ability to cope with data.
The Cloud – A broad term used to describe the practice of using a network of remote servers hosted on the Internet to store, manage, and process data, rather than a local server or a personal computer. The cloud is looked after and maintained (hosted) by a third-party provider.
Cloud Computing – the action of using services or applications which are in the cloud.
Citrix – Citrix is a brand term. The company Citrix sell a number of cloud services and applications, for example, Citrix ShareFile. ShareFile allows businesses to access their files and folders even when they are not in the office. The files and folders are kept in the cloud.
Data Centre – a facility which houses the physical equipment to run computer systems. In the case of the cloud, all data will be physically stored in the data centre.
Disaster Recovery – the process and approach taken when an organisation has to recover after a natural or man-made disaster. When it comes to the cloud this tends to focus on how data will be preserved or recovered following loss of data.
Hardware – computer hardware is the physical stuff of a computer. A mouse is a piece of hardware and so is a circuit board.
Hybrid Cloud – when an organisation keeps some of its IT on the cloud and keeps some of it onsite on a server in-house.
Infrastructure as a Service (IaaS) – The capability provided to the consumer for processing, storage, network and other fundamental computing resources, where the consumer is able to deploy and run software, which can include operating systems and applications.
Onsite Server – An onsite server is a server which is kept physically within an organisation and is usually seen as an alternative to the cloud. Some businesses use hybrid cloud by retaining their onsite server but using some cloud apps.
Platform as a Service (PaaS) – A type of cloud computing where infrastructure is provided but software out of the box isn’t. You’re given a programming platform to build your own software. This kind of service is mainly used by companies who need or want to develop their own bespoke software.
Private Cloud – private cloud is when a cloud infrastructure is created solely for one business. It typically involves virtualising many aspects of IT and is more of a commitment than hybrid cloud, for example.
Public Cloud – public cloud is when a cloud service is available to the general public to use. It can be similar in architecture to a private cloud, but since anyone can sign up to it, it presents different security issues.
Software as a Service (SaaS) – Software as a Service is another type of cloud computing and includes things like Google Apps or Office 365. The application is provided over the web, there is no access to the operating system or main databases, you can’t choose the infrastructure and you simply receive access to the software.
Server – a server is the system which runs the network you are on.
Service level agreement (SLA) – This is a document which defines what the customer can expect from their service and what the provider is bound to ensure. It covers various aspects of the service and in IT can have technical definitions like the maximum mean time between failures, mean time to repair or mean time to recovery. In essence, it ties your provider to a certain speed of recovery should anything go wrong.
Software – a general term to refer to all the different programs used to operate computers and the like. It’s the virtual stuff inside the computer which makes sure that when you click on a document or type in a command the right things happen.
Virtualisation – virtualisation is simply creating virtual, rather than the physical version of things. It’s like being able to create a mini, virtual computer within an operating system which gives you greater flexibility. So you have your original computer and all the things it can do, and within that you can then use programmes and software to create another one (a virtual one).
