Over past 20-30 years enterprise IT has seen many new phases. These were primarily driven by storage capacity, processing power and bandwidth allocation. Along with these a transformational new era of innovation came in form of Cloud Computing!!
Experts believe that this would change the way we design products, market them, collaborate and educate, means in a way it would change how we do our businesses.
Cloud computing is a computing concept wherein large number of computers are connected through a real-time communication network such as internet. It also refers to network based services, which appear to be provided by real server hardware, and are in fact served up by virtu
al hardware and simulated by software running on one or more real machines. Such virtual servers do not physically exist and can therefore be moved around and scaled up (or down) on the fly without affecting the end user – arguably, rather like a cloud.
We all started using ‘Public Cloud’ provided by Microsoft, Google and Apple where we stored documents on their servers. Later came ‘Private Cloud’ where companies started providing secure access to their employees. Now we have something called as ‘Hybrid Cloud’ with combined features of Private and Public cloud.
Industry started with Software as a Service (Saas), but slowly also moving towards hardware as a service, connectivity as a service, collaboration as a service, and security as a service. The real excitement was around implementing everything as a service (XaaS). Clearly, IT is quickly becoming an integrated collection of intelligent services that are on demand, on the move, and on any device.
The concept here is sharing of resources like electricity grid. This achieves coherence and economies of scale. Cloud model is based on ‘Pay per Use’ basis wherein each user pays for his own usage and avoids costs of buying and maintaining dedicated hardware. Cloud resources are shared by multiple users and dynamically re-allocated based on demand.
IT as a service is a game changer, as the sharing of services frees our in-house resources and leaves better scope for innovation. It allows the IT department to examine the industry trends so as to offer better products and services to their customers.
The fact is that the ability to innovate has never been more possible and has never happened faster. In transformational game changing times such as what we’re experiencing now, the key rule is this: If things are possible you better do before others to get first mover’s advantage.
