Cloud Computing is changing the entire computer industry. With “cloud” or “cloud computing”, an individual or a company is able to access the digital resources over the Internet from anywhere across the globe which has connectivity.It is schematically represented here which is self-explanatory for the access a cloud computing can give. It provides a complete managed services.The main advantage of relying on cloud computing is that it either reduces or eliminates the necessity of an onsite software or the hardware. The only thing the user’s computer needs to run is the cloud computing’s interface software which is as simple as the web browser.For instance:You can access your email account from anywhere or any device just by logging onto a cloud-based webmail client.You may work on a document that is originally stored in the home computer by saving the document in the online cloud storage account and access it at workplace later on.Cloud Computing is provided by a third party as a software service or could be built in-house.Cloud Computing Work:Moving further, let us understand the working of cloud computing. It is divided as frontend and backend that is connected to the network or the Internet. The frontend is what the end user sees and the backend is the cloud.The backend comprises of computers, servers, and systems of storage. The central server administers the system, monitors the traffic, and the client demands. It ensures that everything is running smoothly by following a set of protocols using middleware, a software.It Keeps a backup by making copies of the data so that it could be retrieved during an emergency.AlSO READ : 9 Cloud Computing Trends to Look Forward in 2018Types of Cloud Services:It falls into three categories namely, IaaS, PaaS, and SaaS.Infrastructure-as-a-service (IaaS): The cloud provider provides IT infrastructure like the servers, virtual machines, storage, networks, and the operating systems on rent as pay-as-you-go basis.Platform as a service (PaaS): The developers may use the cloud computing services on demand, as they create a web or the mobile apps. They need not worry about the underlying infrastructures needed for development.Software as a service (SaaS): The cloud service providers host and manage the software application, infrastructure, handle maintenance and upgrades including patching. The users just have to connect to the Internet through phone, PC or the tablet.Cloud Deployment Models:They are three types namely, Public, Private and the Hybrid.Public cloud: It is owned and operated by the cloud service provider. One can access the services and manage the account through a web browser.Private cloud: It is used by a single business. The cloud could be located on-site data center or the third-party service provides to host their private cloud.Hybrid cloud: It combines both the private and public clouds which facilitate the sharing of data and applications. It brings more flexibility to the business.Why the businesses and enterprises are behind this cloud computing these days?Let us investigate further.It eliminates the capital cost of buying hardware, software, setup on-site datacenter, and its running costs.It gives flexibility to the business as any amount of data could be resourced at a faster speed and accessed as required from anywhere.Businesses can utilize the time productively as on-site data center management task, upgrade, patch up and other related works are eliminated.Data backup and disaster recovery is easier and cheaper as compared to on-site management and is reliable too saving investment cost.Conclusion:Owing to its simplicity, flexibility, reliability, cost savings, the enterprises are depending more on cloud computing. The adoption is at the global level and it is expected that its adoption will cross 50%.The businesses that tend to be futuristic or aggressive in adopting new technologies are bound to get adopted by cloud technology and thus, reap the benefits of acquiring customers and an increased ROI in no time.Let us know if you have any more ideas to share or reply with your comments here.
