What is cloud computing? & Types of cloud computing

Cloud computing is the delivery of computing services—including servers, storage, databases, networking, software, analytics, and intelligence—over the Internet (“the cloud”) to offer faster innovation, flexible resources, and economies of scale.

Cloud computing is a model for enabling ubiquitous, convenient, on-demand network access to a shared pool of configurable computing resources (e.g., networks, servers, storage, applications, and services) that can be rapidly provisioned and released with minimal management effort or service provider interaction.

There are many essential characteristics of cloud computing, but three of the most important are its scalability, its flexibility, and its cost-effectiveness.

1. Scalability is one of the biggest advantages of cloud computing. With on-demand resources and pay-as-you-go pricing, businesses can easily scale up or down as needed, without having to make huge upfront investments.
2. Flexibility is another key advantage of cloud computing. With a cloud-based infrastructure, businesses can quickly and easily adapt to changing needs and demands, without having to invest in new hardware or software.
3. Finally, cloud computing is also very cost-effective. By using a pay-as-you-go pricing model, businesses only have to pay for the resources they use, when they use them. There are no upfront costs or long-term contracts, which can save businesses a lot of money in the long run.

Types of cloud computing

Cloud computing services can be broadly divided into three main categories:

1. Infrastructure as a Service (IaaS)
2. Platform as a Service (PaaS)
3. Software-as-a-Service (SaaS)

Infrastructure as a Service (IaaS)

Infrastructure as a service (IaaS) is a form of cloud computing that delivers basic computing resources over the internet. IaaS is the most basic form of cloud computing, providing customers with access to storage, networking and computing power on a pay-as-you-go basis.

IaaS is a great option for businesses that want the flexibility and scalability of the cloud, but don’t want to invest in the infrastructure themselves. With IaaS, businesses only pay for the resources they use, making it a very cost-effective solution.

Platform as a Service (PaaS)

PaaS offerings provide a cloud-based environment for developing, testing, deploying and managing applications. PaaS platforms typically include all the necessary tools and services required for application development, making it an ideal solution for businesses that want to quickly launch new cloud-based applications without having to invest in the underlying infrastructure.

Software-as-a-Service (SaaS)

Software-as-a-Service, or SaaS, is a type of subscription software that allows users to access and use the software from a remote location. SaaS is a newer model of software that delivers software over the internet instead of through the traditional software installation process.
