Gone are those days when cloud computing used to be an enigma of sorts. Cloud is no more shrouded in mystery and cloud computing has engulfed almost all spheres of business, entertainment, infotainment, education, and information technology, just to name a few.

Emergence of Cloud Computing as a Mainstream Feature of IT

Nowadays no discussion that covers information technology is complete without the mention of the word ‘cloud’. Cloud has changed paradigms of business processes and has brought about revolutionary changes in the way organizations communicate with internal and external customers.

There were multiple concerns to be addressed before cloud computing could be accepted as an inseparable part of mainstream business. Initial days of cloud adoption were full of skepticism regarding data security, control on cloud hosting environments, and relevance of cloud adoption for mission critical applications. 

There was an air of uncertainty regarding appropriateness of cloud for different category of workloads. This also propelled the growth of private cloud that assured better privacy, security, and control.

Growing knowledge about various aspects of cloud technology has facilitated cloud adoption by businesses. The case in point is the latest Pokémon Go app. The sheer volume of downloads of this app proves the relevance of cloud computing as far as resource scaling is concerned.

Any large scale event such as Pokémon Go must be supported by huge volumes of resources that are instantly scalable. The resources should also be scaled down after the surge in demand recedes once the initial phase of Pokémon mania is over. 

Cloud computing makes it possible to ensure uninterrupted availability of the gaming app in spite of such huge demand from across global locations.

Hybrid Cloud Computing Models

Relevance of Cloud Computing Models and Workload Management

Cloud computing is supporting organizations to stay ahead of the curve by acquiring greater capabilities to manage enhanced website traffic. In fact cloud adoption is essential for better efficiency and higher productivity.

This brings us to a very important aspect of cloud computing models such as public cloud, private cloud, and hybrid cloud. It is quite interesting to see the approach adopted by different organization while choosing various cloud computing models.

Public clouds are built by creating virtualized environments that integrate vast pools of resources that are widespread. These are brought together by leveraging multiple data centers located in different global locations. Private clouds leverage shared pool of resources and is managed by a third party.

Public cloud providers ensure that clients do not face any latency issue by provisioning sufficient resources in real time as per the demand. The most vital feature of public cloud is the excellent level of scalability and reliability. Public clouds are able to draw resources from extensive pool of resources from underlying networks, thereby ensuring reliability as well as scalability.

Public clouds offer excellent cost efficiency due to utility based payment methods. Organizations need to pay only for the resources that are used. This is one of the factors responsible for growing popularity of public clouds.

However, public clouds fall short of expectations in terms of security. Organizations choose public cloud for external workloads because the resources are shared publicly. For more intense and critical applications companies prefer private cloud environments.

Private clouds ensure restricted access and more secured control from within the organizations perimeter. Private and public clouds are capable of managing complex tasks including big data by creating multiple VMs. The resources can also be scaled down as soon as the peak period is over.

If an organization is looking forward to adopt a more dynamic approach, then hybrid clouds can provide the right solution. Private cloud is a blend of public and private cloud. It can create a proper environment for managing external operations that demand capability of managing higher volumes without compromising security and control.

Hybrid clouds offer greater customizability for managing unique applications or exclusive business groups and data sets. The specific requirements of organizations that drive the decision making processes for choosing an appropriate cloud solution is propelling growth of cloud computing.

Coming back to the example of Pokémon Go, there is enough ground to appreciate that the large scale demand that has resulted in almost one hundred million downloads can only be managed by leveraging cloud computing technology.

Niantic must be able to manage internal workloads of storing vital data with help of private cloud and offering the download option by using a public cloud to manage large scale demands.

Cloud computing has reached a stage of maturity with organizations using the various models for fulfillment of different business objectives. This has resulted in growth of different models of cloud computing with hybrid cloud computing being viewed as the suitable solution to manage critical workloads.
