"The cloud" refers to servers that are accessed over the Internet, and the software and databases that run on those servers. Cloud servers are located in data centers all over the world. By using cloud computing, users and companies do not have to manage physical servers themselves or run software applications on their own machines.

Cloud computing is on-demand access, via the internet, to computing resources—applications, servers (physical servers and virtual servers), data storage, development tools, networking capabilities, and more—hosted at a remote data center managed by a cloud services provider (or CSP). The CSP makes these resources available for a monthly subscription fee or bills them according to usage.

There are three main types of cloud computing: public cloud, private cloud, and hybrid cloud. Public cloud services are provided by third-party providers, and the infrastructure is shared among multiple organizations. Private cloud services are provided by an organization's own users. A hybrid infrastructure, and the services are only available to members of that organization. A HYBRID cloud is a combination of both public and private cloud services.

With 25% of organizations planning to move all their applications to the cloud within the next year, it would seem that cloud computing use cases are limitless. But even for companies not planning a wholesale shift to the cloud, certain initiatives and cloud computing are a match made in IT heaven.

How Important is the cloud?

Building the infrastructure to support cloud computing now accounts for a significant chunk of all IT spending, while spending on traditional, in-house IT slides as computing workloads continue to move to the cloud, whether that is public cloud services offered by vendors or private clouds built by enterprises themselves.

Creating web applications on a server
Building workflows that can be used in conjunction with software
Connecting to database systems
Reading and modifying files
Performing complex mathematics
Processing big data
Fast prototyping
Developing production-ready software.

Cloud computing without limits:

Cloud computing without limits can mean different things depending on the context. It could mean that there are no limits on the amount of data that can be stored or processed in the cloud. For example, IBM Cloud offers over 40 always-free products with no time limit.

The Future is cloud based

The future of cloud computing is bright and it is expected to be an integration of physical computing alongside cloud-based software products. This futuristic model helps to build hybrid and optimum IT solutions for present-day business needs¹. Businesses have already realized the benefits of using several types of cloud computing because hybrid clouds offer much more flexibility than leveraging solely private or public clouds.
