Cloud-based networking solutions are services that establish cost efficiency and scalability benefits to the networking sphere. It is a system where software programs and storage space can be accessed through the Internet. Hence companies use this service to outsource the ownership and management of certain areas of its IT functionality like storage, mail room, web sites, etc within the cloud. Users may not be aware of what software or hardware is being used or what operating system it is running on, but they do not need to. It is similar to software as a service (SaaS) in the market. This is also an enterprise application. Multi-tenant architecture based SaaS applications like SalesforceTM has changed the status quo in the Customer Relationship Management space. Cloud-based networking has brought about the same upheaval in the networking space.
Cloud-based networking has created waves in the internet sphere. It is an innovative way to roll out distributed venture networks that convey enterprise-class network capabilities around the world. The process is carried out via vastly resilient, multi-tenant applications that involve no principal investment in networking equipment. Unlike conventional hardware-based solutions, cloud-based networking is extremely simple, enabling enterprises to install remote locations in less time and operate their distributed networks through a cloud-based application. It also provides unique levels of centralized control and network visibility. Such services are also subscription based which the users can opt.
The two major features of the cloud computing are:
(i) It is modular and it compartmentalizes software applications ,associated hardware and the infrastructure
(ii) It is uniform and utilizes the same possessions that clients share. A business using cloud computing can keep away from large outlays of capital expense as well as everlasting maintenance costs. This results in the cash flow with total system cost.
Apart from the above mentioned, there are other benefits to cloud computing. The major one being it supporting data centers in every aspect. Data centers can at times be too bunched up for comfort. Virtualizing the servers has met with only limited triumph. Over time, there will be a smooth transition to measurable computing, based on the cloud. The future of computing is going to be a blend of service orientation, service management, and cloud computing. Some of the reasons being –
• Customers can access applications and data from anywhere at any time through the internet. Data will be stored offsite rather than being stored on a hard drive of a user’s computer or a corporation’s internal network.
• Another important aspect is that the hardware costs would decline as cloud computing systems would lessen the need for advanced, expensive hardware on the client side. The cost of buying, installing and supporting a system network will dramatically decline.
• The need for expensive memory or even large hard drives is undesirable. Rather, everyone would buy an reasonably priced computer terminal, a monitor, input components such as a keyboard and mouse, and only enough processing power to run the middleware essential to connect to the cloud system. Computer components have to be purchased in large quantities in IT. But buying hardware in large volume, cloud suppliers get better pricing on each purchase.
Cloud computing is a subscription based system. Enterprises would not have to buy software or software licenses for each employee in the company. Instead, the company would pay for what they use. It is more like the way an open source software functions. In a broader sense, cloud computing infrastructures are fabricated from open source components as the cloud providers are uncertain to make huge investments without knowing the outcome.
When cloud computing system’s back end is a grid computing system, customers could make optimum use of the entire network’s processing power. For example, researchers who work with extremely complicated computation can dispatch the computation to the cloud for processing purpose. The cloud system would make use of the processing power of all available computers on the back end and considerably speed up the results. Cloud computing offers a way to outsource non-critical applications to business. It also results in better performance, allowing IT to hub on critical applications.
Another advantage of using Cloud computing is the usage of man power. Cloud providers are more resourceful at IT operations, using fewer man-hours for criterion tasks.
