What is Cloud Computing

About Cloud Computing

Cloud Computing is use for store data on internet and may more...

Cloud Computing is a computer which present in remote place and using the internet any one can access and get the performance of that computer.

A cloud can be private or public. A public cloud sells services to anyone on the internet. A private cloud is a proprietary network or a data center that supplies hosted services to a limited number of people, with certain access and permissions settings. Private or public, the goal of cloud computing is to provide easy, scalable access to computing resources and IT services. 

Communications between the front and back ends are managed by a central server. The central server relies on protocols to facilitate the exchange of data. The central server uses both software and middleware to manage connectivity between different client devices and cloud servers. Typically, there is a dedicated server for each individual application or workload.

The cost of physical hardware. servers and details of specifications like CPUs, cores and RAM, plus the cost of storage. You'll also need to calculate the cost of applications. 

whether you plan to dump them, re-hosting them in the cloud unchanged, completely rebuilding them for the cloud or buying an entirely new SaaS package each option will have different cost implications.

The cloud business case also needs to include people costs (often second only to the infrastructure costs) and more nebulous concepts like the benefit of being able to provide new services faster. Any cloud business case should also factor in the potential downsides, including the risk of being locked into one vendor for your tech infrastructure.

How cloud computing work

When Using cloud computing than owning their own computing infrastructure or data centers, companies can rent access to anything from applications to storage from a cloud service provider. 

One benefit of using cloud computing services is that firms can avoid the upfront cost and complexity of owning and maintaining their own IT infrastructure, and instead simply pay for what they use, when they use it. 

In turn, providers of cloud computing services can benefit from significant economies of scale by delivering the same services to a wide range of customers.

There are three types of cloud computing services.

1. Public Cloud

2. Private Cloud

3. Hybrid Cloud

1. Public Cloud:

    This model consists of services and infrastructure that are shared by all organizations. With huge available space, scalability becomes easier in public cloud solutions. Organizations pay public cloud models on a pay-per-use basis, making it a suitable solution for smaller businesses looking out to save money.

2. Private Cloud

This model consists of an infrastructure that is owned by a single business. This model can be hosted in-house or can be externally hosted. Although expensive, the private cloud model is well suited for large organizations with a focus on security, customizability, and computing power.

3. Hybrid Cloud

A combination of both public and private clouds, a hybrid cloud combines the two models to create a tailored solution that allows both platforms to interact seamlessly.
