What is Cloud Computing

Introduction of Cloud Computing

Cloud computing is providing computing services like- servers, databases, networking, security, storage, software, and intelligence through the internet. This is a very reliable service for growing and faster your business or working through these computing services. One and most beneficial thing is that you would pay only for the cloud services you use, these Cloud computing services help you to fast up your work at a low cost, and run your infrastructure more efficiently.

The top advantage of Cloud computing

Cloud computing has top advantages for making your business think about IT resources. There are seven common reasons to switch many organizations to Cloud computing services:

Cloud Computing

Reliability and availability

If anyone using computing services a user can use that service anytime and anywhere, and computing service teams are always available for the user. It makes cloud computing services more beneficial for users.

Cost or reduce lots of capital

Whenever you want to host a website or deploy software to someone, it will take lots of investment in machines, license keys, systems, internet, database, storage, and software these things take lots of capital. Cloud computing takes only what services you using, you will pay only for them. (reduces these all investments and gives you great services to make your work easier and faster).

Increase scalability

The benefit of cloud computing is having good scalability. How many resources the user wants, computing service will give to the user according to need. For example, high or low computing power, storage, and bandwidth-it are provided at the right time or right location for what the user wants.


Cloud computing provides on-demand or user-needed services, therefore it’s easy to load services in a few minutes or even a few clicks can make your business more reliable and flexible.


IT companies want lots of “data centers and hardware set-up” and patching software. Cloud computing removes the need for many tasks. So IT teams can put their time into other more important tasks.

Increase performance

Cloud computing is a worldwide network of secure data centers it gives high-performance services with security and upgrades with the latest generation. Increase performance and reduce network latency for applications and greater scalability.


Cloud computing provides you with a high-security level, including a secure database, application, and secure infrastructure, and helps to protect your data.

Cloud computing types

Cloud computing have different types, and every type of cloud computing uses different models. Let’s take a look at the types of cloud computing:

Public cloud

The public cloud is open to the public anyone can use resources as per their need. The services are free or on-demand user pay for cloud services according to the usage of bandwidth, and networking. For example, every employee of a company uses the same application and accesses all services anytime or at any branch of the company.

Private cloud

A private cloud works on a private platform only one company and organization can use the services. A private cloud locates in a single company’s online datacenters. A private cloud has more security and privacy than a public cloud. One disadvantage of a private cloud company’s IT department is responsible for the cost of services and usage. for example, HCL makes a private cloud server so only HCL employers can run these cloud servers.

Hybrid cloud

A hybrid cloud works with public and private clouds both. A hybrid cloud turns the private cloud into a public cloud by giving access to users with security. A hybrid cloud gives you more flexibility, and deployment options, and helps you to upgrade your current infrastructure and security.

Cloud computing services types: IaaS, PaaS, Serverless, SaaS

Cloud computing has four types of services, infrastructure as a service (Iaas), platform as a service(Paas), serverless, and software as a service(Saas). Let’s see cloud computing services types, how work, or which one is best for any organization or company.

Infrastructure as a service (IaaS)

Infrastructure as a service (Iaas) is one of the basic categories of cloud services. In Iaas you rent IT- infrastructure, virtual machines, storage, networks, and operating systems from cloud providers you pay as per your usage.

Platform as a service (PaaS)

Platform as a service provides your development and deployment environment in the cloud, with their resources, you will get secure resources over the internet. Paas just like Iaas, has storage, networks, operating systems, and datacenter– but also middleware, Development tools, database management, business analytics, operating system, and more.


Serverless computing makes developer efforts easy and using serverless computing they can faster deploy their applications on a server with less effort or cost. The cloud service provider will automatically manage the workload and gave the infrastructure that is required to deploy an application.

Software as a service (SaaS)

Software as a service (SaaS) full software solution that you purchase as your usage from a cloud service provider. SaaS’s common example is the calendar, mail, and Microsoft Office 365.

SaaS provides all of the infrastructure, middleware, app software, and app data, or all data is located in the cloud provider’s data center. The service provider manages the hardware and software, all app data are secured by service providers.

What are the uses of cloud computing

Cloud computing services are everywhere even if you can not realize that you are using cloud services, like you working on any website to store data, sending mail, keeping files in secure online storage, watching TV, or playing games. Behind all of these things cloud computing services make it easy and possible for you. Cloud computing services are working for big organizations tiny start-ups, government agencies to non-profits.
