Cloud computing is a method of delivering computing services including servers, storage, database, networking, software, and analytics over the internet. This helps in ensuring faster innovation, flexible resources, and easy scalability. The main purpose of cloud computing is to grant user access to data centers. Using cloud computing, users can access data from remote servers.
Types Of Cloud:
- Private Cloud: It is used for intra-business interactions, where the computing resources are deployed for a single organization.
- Community Cloud: In this type, the computing resources are deployed for a single community and organizations in the community.
- Public Cloud: This type of cloud computing is used for B2C interactions and the computing resources are owned by government or an academic/business organization.
- Hybrid Cloud: It is used for both B2B and B2C interactions. The computing resources are bound together by different clouds.
Cloud Computing Services:
- Software as a Service (SaaS): It is a software distribution model in which the cloud services are hosted by a service provider and made available to the client over internet. Clients can subscribe to the software and pay for monthly usage.
- Platform as a Service (PaaS): It provides a platform to developers for building applications and services. PaaS services are regularly updated with new features. It includes software support and services, storage, networking, deploying, testing, collaborating, hosting and maintaining applications.
- Infrastructure as a Service (IaaS): It provides computing infrastructure like virtual server space, network connections, bandwidth, load balances, and IP addresses. The pool of hardware resources is extracted from multiple servers and networks distributed across numerous data centers.
Benefits Of Cloud Computing:
- Cost Effective: Cloud computing eliminates the capital investment required to buy hardware/software and set up on-site data centers. It also reduces the cost incurred on hiring IT professionals for running and maintaining the data centers.
- Speed: Cloud computing allows businesses to be flexible and ensure seamless capacity planning. Also, cloud computing services are delivered on-demand, so vast amount of computing resources can be provisioned in a short time.
- Productivity: On-site data centers require a lot of hardware setup, software patching, and other IT management tasks. Cloud computing removes the need for these tasks, thus freeing the time and resources of IT team which can be focused on other productive tasks.
- Lesser Downtime: Cloud services allow businesses to bring data centers closer to the users, irrespective of their geographical location. This helps in reducing the downtime.

Cloud computing offers an array of benefits to organizations and thus, it has become a popular choice for data storage and computing. Depending upon individual business requirements, organizations can choose between private cloud and public cloud solutions.
Private Cloud: It is a model of cloud computing where IT services are provisioned on-premises over private IT infrastructure for dedicated use by single organization. It is managed by internal resources of the organization.
Public Cloud: In public cloud model, computing services are offered by a third party over public internet to multiple client organizations as per their capacity or usage requirement. It is managed by the service provider and organizations have to pay according to the storage or bandwidth consumed by them.
However, a new term ‘Hybrid Cloud’ has emerged in recent years. A hybrid cloud combines the services of a private and public cloud to allow seamless sharing of data between them. The organizations can run their workloads partially on private cloud and rest in public cloud. This prevents public or third party service providers from gaining access to entire data of the business.
Working Of Hybrid Clouds
- Private and public clouds work independently in a hybrid cloud setup.
- The resources are abstracted and pooled into private and public clouds by virtualization.
- These abstracted resources are then allocated by automation.
- Management tools provision new environments.
- A hybrid cloud functions properly when APIs, VPNs or WANs connect the private & public clouds as seamlessly as possible.
- The interconnectivity between public and private clouds is the underlying concept for a functional hybrid cloud.
Benefits Of Hybrid Cloud Infrastructure
- It is a cost effective approach. Organizations can use private cloud for managing regular workloads and pay for extra usage on public cloud only when there is a need for scalability arising due to an occasional increase in workload.
- The approach helps in separating sensitive or critical workloads from regular data. Organizations employing hybrid cloud approach have the benefit of storing critical financial data, customer information, etc. on their private cloud while utilizing public cloud to run general applications.
- Public cloud resources can be used for allocation to short-term projects, instead of spending money on buying on-premises hardware and infrastructure for temporary use.
- The availability of private cloud resources facilitates testing of applications as it grants back-end access to the developers.
- Hybrid cloud infrastructure integrates the public cloud computing and private cloud which allows the organization to have control over security and regulations.
- It offers excessive flexibility. A hybrid cloud setup can be scaled up to the use of public cloud or scaled down to private cloud as per the demand.
