The world of technology is ever changing, and with such fast growth comes a deluge of new words, terms and phrases that none of us were previous aware of. Topics such as “cloud” and “the internet of things” have been floating around across the past year, but just what do they mean?
Let us make things simple and explain these to you in a way that informs you and allows you to make the decision on whether any of this new technology would be of a benefit to your company.
Cloud Computing refers to a network of remote servers hosted on the Internet rather than a local server or computer which are used to process, manage and store data. Cloud Computing is broken down into three common service levels: SaaS, PaaS and IaaS.
SaaS: Software as a Service (SaaS) is a software delivery method over the internet. The software is hosted remotely, so organisations do not need to invest in additional hardware. Software as a Service removes the need for organisations to handle the installation, set-up and often daily upkeep and maintenance, meaning leaner and more responsive IT resources.
PaaS: Platform as a service (PaaS) is a category of cloud computing services that provides a computing platform and a solution stack as a service. Along with software as a service (SaaS) and infrastructure as a service (IaaS), it is a service model of cloud computing.
IaaS: IAAS is the acronym for Infrastructure as a Service. IAAS describes the delivery of IT infrastructure such as servers and storage on demand over the internet, through an outsourced IAAS service provider.
Desktop-as-a-Service Desktop as a Service (DaaS) is a cloud service in which the back-end of a virtual desktop infrastructure is hosted by a cloud service provider. DaaS has a multi-tenancy architecture and the service is purchased on a subscription basis.
Hybrid cloud The hybrid cloud is a mix of public cloud and private cloud services, maintained by both internal IT teams and external cloud computing providers. The hybrid cloud is the solution of choice for those users who need both a local server running specific applications and a cloud hosting service that offers additional applications, files, or databases. These elements are configured to operate together to make up the hybrid cloud solution.
Latency Latency is a time interval between the stimulation and response or, from a more general point of view, as a time delay between the cause and the effect of some physical change in the system being observed.
Unified communications Unified communications is the integration of real-time communication services such as instant messaging, presence information, telephony, video conferencing, desktop sharing, data sharing, call control and speech recognition with non-real-time communication services such as unified messaging.
The Internet of Things The internet of things essentially consists of connecting everyday items to the internet. In theory anything with an on/off switch can be connected to the internet and be able to communicate with other devices. From items in the household, to within big corporations and built in to the landscape surrounding us – the possibilities IoT creates are exponential. For a further explanation please refer to our recent blog post: “What is the “Internet of Things?”
We hope that this has given you some insight and explanation with regards to some of the key technology phrases being used at the moment. Of course, over 2015 there will no doubt be a whole host of new ones but we will endeavour to explain these as simply as possibly both here and on our Glossary of Terms.
