Over the past few years, cloud computing has taken off in a big way. It might seem as if this technology has come from nowhere, but the idea of such a network was considered up to 47 years ago. Then, J.C.R. Licklider spoke of a possible “intergalactic computer network” that would link all data and programs and allow people to access it any time of day or night, and from any location. Now, with the cloud computing era here, it’s up to businesses to adopt this modern architecture or be left behind by the competition.
During the coming years, the cloud computing industry is set to grow at a staggering speed. In 2015, the industry was valued at $4.68 billion. From now until 2020, however, analysts predict a CAGR of 25.7%, and this could mean that in just four years’ time, the sector could be worth $14.7 billion. Over the same period of time, the on-premises solution market is set to grow by 4% at best.
With cloud computing really making its mark on the world, it’s essential for CIOs to inform themselves on the various architectures available. There is no perfect fit when it comes to matching cloud technology to a business, and the foundation architecture for each solution will have a major effect on availability, customisation, speed, security, functionality and innovation.
The four main cloud types consist of the private cloud, the single tenant public cloud, the monolithic multitenant public cloud and the microservice multitenant public cloud. The private cloud is often people’s port of call, especially for those wanting to utilise cloud-like services but ensure the system is completely secure. It also means that high levels of customisation are available. However, for many, a public cloud is more affordable. In the single tenant model, each firm is able to utilise their own instance of the contact centre application. This results in a highly secure environment that is customisable and flexible when it comes to timing updates. Monolithic, meanwhile, provides limited scale, reliability and innovation, largely because the system allows several customers to use one application. Finally, the microservice platform is the most revolutionary system and one that many people utilise. These platforms are broken into many hundreds of applications, each of which can run on its own without affecting the others.
Each available architecture is quite different, and CIOs must evaluate the various options. Though businesses don’t need to immediately throw out their current system, thought must be given to including modern cloud computing or risk losing out to competitors.
