Cloud Computing is the delivery of computing services such as servers, storage, databases, networking, software, analytics, intelligence, and more, over the Cloud (Internet).
Cloud Computing provides an alternative to the on-premises data center. With an on-premises data center, we have to manage everything, such as purchasing and installing hardware, virtualization, installing the operating system, and any other required applications, setting up the network, configuring the firewall, and setting up storage for data. After doing all the set-up, we become responsible for maintaining it through its entire lifecycle.

1) What is Cloud Computing?
Cloud computing is the delivery of different services through the Internet, including data storage, servers, databases, networking, and software. Cloud-based storage makes it possible to save files to a remote database and retrieve them on demand. Services can be both public and private-public services are provided online for a fee while private services are hosted on a network to specific clients. Cloud management is the management of products and services. Public clouds are managed by public cloud service providers, which include the public cloud environment’s servers, storage, networking and data centre operations. Users may also opt to manage their public cloud services with a third-party cloud management tool.
2) Purpose of Cloud Computing
- Cost: It reduces the huge capital costs of buying hardware and software.
- Speed: Resources can be accessed in minutes, typically within a few clicks.
- Scalability: We can increase or decrease the requirement of resources according to the business requirements.
- Productivity: While using cloud computing, we put less operational effort. We do not need to apply to patch, as well as no need to maintain hardware and software.
- Reliability: Backup and recovery of data are less expensive and very fast for business continuity.
- Security: Many cloud vendors offer a broad set of policies, technologies, and controls that strengthen our data security.
3) Types of Cloud Computing
- Public Cloud: The cloud resources that are owned and operated by a third-party cloud service provider are termed as public clouds. It delivers computing resources such as servers, software, and storage over the internet
- Private Cloud: The cloud computing resources that are exclusively used inside a single business or organization are termed as a private cloud. A private cloud may physically be located on the company’s on-site datacentre or hosted by a third-party service provider.
- Hybrid Cloud: It is the combination of public and private clouds, which is bounded together by technology that allows data applications to be shared between them.
4) Components of Cloud Computing
- Infrastructure as a Service
Here end-users rent cloud as an infrastructure for their companies. They choose a cloud computing provider such as Amazon EC2, Rackspace Cloud, etc. to utilize their servers and storage devices based on their requirements. Businesses can run any operating systems on the servers and configure it to host web and other types of applications without buying new hardware and actively maintaining it.
5) Advantages of IaaS
- Business Continuity – Cloud technology keeps your company data replicated on multiple data centres across the globe, which allows you to run your business even if some natural or human-made disasters occur.
- Faster Scaling – IaaS eliminates the requirement of manually provisioning servers when there is fluctuation in computing power demand. It automatically allocates and deallocates resources in real-time so that you are paying for only what you use.
- Focus on business – Allows companies to focus on building their business rather than worrying about IT infrastructure.
Platform as a Service (PaaS) provides the resources to development and deployment platform to businesses. From simple cloud-based applications to complex, sophisticated enterprises, you can develop and deploy any application. PaaS offers a framework that developers can use to develop an application on top of it. Various cloud features such as scalability, high-availability, and multi-tenant capability reduce the amount of coding that developers must do.
6) Advantages of PaaS:
- Reduce coding time
- Develop for multiple platforms at once
- Makes sophisticated software affordable to use
- Support distributed remote workforce
Software as a Service is a cloud-based software delivery method that allows users to access data via the internet anytime from any device. Here, software vendors host their applications on the cloud and allow users to subscribe to their software for access.
One of the main advantages of
- SaaS is that it offers greater customizability for businesses.
- made easy using the SaaS model.
- your data is safe and secure.
7) Examples of Cloud Computing
- Examples of Cloud Storage
- Ex: Dropbox, Gmail, Facebook
- Right now, Dropbox is the clear leader in streamlined cloud storage allowing users to access files on any device through its application or website with up to 1 terabyte of free storage.
- Examples of Marketing Cloud Platforms
- EX, Hubspot, Adobe Marketing Cloud
- A marketing cloud is an end-to-end digital marketing platform for clients to manage contacts and target leads.
- Examples of Cloud Computing in Education
- Ex: SlideRocket, Ratatype, Amazon Web Services
- Education is increasingly adopting advanced technology because students already are. So, to modernize classrooms, educators have introduced e-learning software like SlideRocket.
- Examples of Cloud Computing in Healthcare
- Ex: ClearDATA, Dell’s Secure Healthcare Cloud.
- Cloud computing lets nurses, physicians, and administrators share information quickly from anywhere.
- Examples of Cloud Computing for Government
- Uses: IT consolidation, shared services, citizen services
- TheU.S. government and military were early adopters of cloud computing.
8) Security and Privacy in Cloud Computing
- Cloud computing poses privacy concerns because the service provider can access the data that is in the cloud at any time. It could accidentally or deliberately alter or delete information.
- Many cloud providers can share information with third parties if necessary for purposes of law and order without a warrant. That is permitted in their privacy policies, which users must agree to before they start using cloud services.
- Privacy solutions include policy and legislation as well as end-users’ choices for how data is stored.
- Users can encrypt data that is processed or stored within the cloud to prevent unauthorized access.
Cloud computing helps businesses eliminate various IT hassles and reduce operational costs. The current technology and future’s next big thing as it is a home of many industrial trends such as data science, Internet of Things, machine learning, and artificial intelligence.
