Types of Cloud Computing

Cloud computing is a technology that uses a large number of remote servers to store data. It is used to deliver software, applications, and other business processes over the Internet. There are many types of cloud computing services available, including SaaS, IaaS, and PaaS. The most popular of these is SaaS. Using this type of computing model, you only pay for the resources you use. For example, you only pay for the amount of bandwidth and CPU cycles that you use. Unlike other cloud models, SaaS is not tied to a specific provider, allowing you to work with any vendor you like.
IaaS is a cloud computing service that allows businesses to rent remote IT infrastructure. Most companies begin their journey to cloud computing by using IaaS. They use it for big data and to scale their applications. Typically, an IaaS provider will provide virtual machines, which can be accessed over the internet. This is a cost-effective way to move your IT environment to the cloud.
Software as a Service (SaaS) is a newer cloud computing model that provides all the layers of the IT stack, allowing customers to create, deploy, and manage applications. The application is accessed over the internet, usually through a web browser. Many cloud services include dashboards that allow you to view your data and access it from anywhere. You can access the SaaS application from virtually any computer, tablet, or smartphone. Examples of SaaS tools include Office 365, MailChimp, Google Apps, and Basecamp.
PaaS is another cloud computing service that allows organizations to deploy software quickly and easily. It provides the necessary components, including the operating system, runtime, and storage, to build and run applications. Typically, providers of this service will also manage the servers and middleware.
If you need to manage applications or other workloads on a continuous basis, you should consider a hybrid cloud. Hybrid clouds combine the best of both worlds, allowing you to maintain flexibility and security while moving your workloads between on-premises, private, and public clouds. But beware of the maintenance costs associated with hybrid cloud. Those costs can be expensive, especially if you are managing multiple cloud providers. Depending on your needs, you may choose a cloud service that allows you to operate on a multi-tenancy basis, which allows several different organizations to share the same applications.
Another type of cloud computing model is called Community Cloud. This is an infrastructure shared by several organizations, which supports the same mission, policies, and compliances. However, it does not offer the same security as a private cloud. Alternatively, you can opt for a self-hosted private cloud, which lets you control your own infrastructure and tailor it to your own requirements.
Multi-clouds are a recent addition to the cloud service offerings. Generally, a user pays for only the storage capacity and bandwidth, which is used by the applications. Whether you choose a public or private cloud, you will have access to corporate information from any location, on any device, and in any format. Depending on the type of data you have, you may require different types of cloud security.
