Cloud computing is the delivery of computer services via the Internet or “The Cloud”. These services include servers, storage, databases, networking, software, analytics, and intelligence.
Rather than managing files on a local storage device, cloud computing makes it possible to save them over the internet. As long as an electronic device has internet connectivity, it has access to the data as well as the software applications needed to run it.
Why Cloud Computing?
- Cost – Cloud computing reduces the expenses of purchasing hardware and software, as well as the costs of constructing and operating data centers.
- Scalability – Cloud computing allow you to pay for how much you use, with much easier and faster provisions for scaling up or down.
- Server Storage – Cloud computing solutions are provided by cloud service providers (Azure, AWS, Google Cloud Platform), which operate and maintain the servers on your behalf, saving you money and space.
- Security – Many cloud providers provide a comprehensive set of policies, technologies, and controls to help you improve your entire security posture and safeguard your data, apps, and infrastructure from attacks.
- Reliability – Cloud computing enables data backup, disaster recovery, and business continuity easier and less expensive because data may be replicated at several redundant sites on the cloud provider’s network.
Types of Cloud Computing
- Public
Cloud – The cloud infrastructure is made available to the general public over
the internet and is owned by a cloud service provider.
- Amazon Elastic Compute Cloud (EC2), Microsoft Azure, IBM’s Blue Cloud, Sun Cloud, and Google Cloud are examples of the public cloud.
- Private Cloud – The cloud infrastructure is exclusively operated by a single business or organization. A private cloud can be physically located on the company’s on-site datacenter.
- VMWare, Oracle, Dell, IBM / Red Hat, Microsoft, Cisco are examples of the private cloud.
- Hybrid
Cloud – It consist the functionalities of both public and private cloud.
- Hybrid cloud is commonly utilized in larger hospitals; more specifically, in healthcare services, where the IT model transfers patient data within healthcare facilities to insurance firms, allowing insurance service providers to access data.
