What is Open Cloud Computing Technology – How it works? Open Cloud Explained in a detailed guide
In the last decade big data has emerged as the most vital component to run the world, and data management via cloud computing as the most crucial of all professional practices that manages the universal workforce. Because of the fact of the entire data being properly managed, the world has become a relatively smaller place and globalization has resulted into increased economy and human life is advancing at a pace that could never have been imagined. The entire ecosystem that revolves around data is regulated by the concept of cloud computing, not only is this concept much talked about but also is one of the biggest research topics across the world.
Cloud Computing Overview and Workflow process
Imagine a country like India that is one of the largest growing country in every term, be it the population rate or the economic rate of the country. The world’s largest democracy has the most no. Of religions and lifestyle trends to be followed , Managing such a big population can be hectic task for the government. Now let’s consider that every Indian located in any part of the world has some Indian government record and wants to access it, How would that process be ? First, he would login to the government department’s website and access it, the access would happen to an Indian server from any other part of the world where that Indian is located and this may take some long time apart from some accessibility issues. Second, let’s assume that the person is connected to a local server in his own country that in turn is only connected to the Indian server when the user is logged in for the same, This reduces the load on the Indian server and hence increases the efficiency. In the first place the Indian Government would have to maintain a huge stack of servers at a single place, but in the second place small virtual servers can be located across various countries to make it relatively easier for people to access it globally. That’s the power of a Cloud.
Therefore, cloud computing lays stress on utilizing small resources scattered across places rather that a single place as per the requirement and making available loads of computing resources to access the big data in any part of the world with minimal workforce and infrastructure required.
Advantages of Cloud Computing Technology
- Virtualization : Rather than having dozens of servers to manage data at a single place, let us imagine having small virtual servers scattered globally and hence reducing not just the costs but the resources too.
- Flexibility and scalability : Within a few clicks, more data resources could either be added or removed, rather than having physical hardware at a place to be configured, this seems like more of a plug and play model for infrastructure.
- Economic : It is much cheaper as compared to physical servers and hence an unmatched pricing.
- Open-ness: A cloud is openly available to be moved from one place to another easily and it doesn’t comes under the purview of any patented technology or organisation.
- Simplified Businesses : It not only streamlines the processes involved in day to day businesses but also makes it easier to manage the day to day stuff , either internally or one could also outsource it externally as per his own convenience as the entire data is on the cloud.
Cloud Operational & Delivery Models
Cloud computing at the moment is operational via three modes :
- S-a-a-S : This model offers the software as a service that means that the user here has a pay as you go model and doesn’t retains back either of the network or the physical hardware.
- P-a-a-S : This model focuses over the platform as compared to the software in the above, In the above model the user rents out the software , but here the user acquires the platform and is free to run any software on it as compared to the software, here also the user has no hold over the network or the hardware’s associated etc.
- I-a-a-S : This is the most typical model and generally users prefers not going by this model because this is relatively costlier as in this case the entire infrastructure to setup the cloud , the network and everything associated is owned by the user and hence making it a 100% self owned cloud.
How to Deploy a Cloud
A cloud can be deployed as the below mentioned four models :
- A publically available cloud : This is the most economic and easiest method to deploy and access data, available via third party providers and with a lot of flexibility options , this may either be free or very inexpensive as compared to other web hosting or servers.
- A privately available cloud : Unlike the above , on a private cloud not all users can signup, the access on who can access the private cloud is limited to a particular organisation or the user. There might not be any issues like that of a bandwidth usage etc. As may appear in a public cloud because the entire cloud is accessible to a entity in this case.
- A community driven cloud : In this case, if there is a community of people or organisations who want a specific set of features, then this cloud is used in place. A limited set of applications are put up on the entire cloud and made accessible to all the users.
- Hybrid model Cloud : This model is a combination of a public and private cloud in which the users are accessing some data publically while some data is kept secret and is accessible only to people with certain set of permissions to access the same.
