Cloud computing is the distribution of computer services over the Internet (“the cloud”) to provide faster innovation, more versatile resources, and economies of scale. You typically only pay for the cloud services you use, which will help you reduce costs, operate your infrastructure more efficiently, and scale as your business grows.
Different types of Cloud Computing
Not all clouds are created equal and not all forms of cloud computing are suitable for every situation. The cloud tools needed to control a solar power system, for example, may be different from the tools needed to process business transactions. Various models, sizes and services have appeared to help you find the best solution for your needs.
To get started, you need to decide on the type of cloud deployment or cloud computing architecture that will be used to deploy your cloud services. Cloud services can be deployed in three ways: public cloud, private cloud, or hybrid cloud.
Third-party cloud service providers own and run public clouds, which distribute computer services such as servers and Internet storage. A public cloud, such as Google Drive, is an example. The cloud provider owns and manages all the hardware, applications, and other support resources in a public cloud. A web browser is used to access these resources and maintain your account.
A private cloud is a collection of cloud computing services used solely by a company or organization. A private cloud is usually physically hosted in a company’s data center. Some companies often pay for their private clouds to be hosted by external service providers. The services and infrastructure of a private cloud are managed on a private network.
Public and private clouds are combined into hybrid clouds, which are connected using technology that allows data and applications to be exchanged between them. A hybrid cloud gives your business more flexibility, more deployment options, and helps you leverage your current infrastructure, protection, and application, enabling data and application migration between public and private clouds.
Even if you don’t know it, you’re probably using cloud computing right now. Whether you use an online service to send emails, edit documents, watch movies or TV, listen to music, play games, or store photos and other information, cloud computing is almost certainly the center of it. Although the first cloud computing services were only launched a decade ago, a wide range of organizations — from small businesses to multinationals, government departments, and nonprofits — now use technology for a variety of purposes.
Other cloud services
Without being too technical, here are some other services the cloud offers. Platform as a service (PaaS), computing without a server, and software as a service are three types of cloud computing services. Because they are built on top of each other, they are often referred to as “stack” cloud computing. It’s easier to achieve your business goals if you know what they are and how they vary.
As a business platform (PaaS)
Cloud computing platforms that provide an on-demand environment to design, test, distribute, and manage software applications are called platform-as-a-service. PaaS was designed to make it easy for developers to create web or mobile applications quickly without having to worry about configuring or managing the underlying server infrastructure, storage, network, and databases.
Computer without server
Serverless computing, which overlaps with PaaS, focuses on developing application functions without having to constantly manage the servers and infrastructure needed to do so. The cloud provider manages configuration, space planning, and server management. Serverless architectures are scalable and event-based, meaning that they only use resources when a given feature or cause occurs.
Software as a service
Software as a Service (SaaS) is a method of distributing software applications to the Internet on demand and usually by subscription. Cloud vendors can host and manage underlying software applications and infrastructure, as well as perform maintenance, such as software updates and security patches, using SaaS. Users access the application over the Internet, usually through a web browser on their phone, tablet, or computer.
