With the increasing popularity of cloud environments, more and more enterprises are getting rid of local IT solutions and gradually relying on cloud environments. When choosing cloud services , we often see terms such as IaaS, PaaS, and SaaS, so What do these three terms mean? How to choose? What is the difference between the three?
Before explaining IaaS, PaaS, and SaaS, we need to first understand cloud computing .
Cloud computing is the provision of different services over the Internet, including tools and applications such as data storage, servers, databases, networks and software. Instead of saving files on a proprietary hard drive or local storage device, cloud-based storage They can be saved to a remote database and as long as the device has access to the network, the data and the software program running it can be accessed.
is so named because the information being accessed is found remotely in the cloud or virtual space. Companies that provide cloud services enable users to store files and applications on remote servers and then access all data over the network.
Then we will introduce these three types in detail below.
[IaaS]
providers provide users with access to computing resources such as storage, networks, and servers, and companies use their own platforms and applications within the service provider's infrastructure.
[PaaS]
providers provide customers with a complete application development environment , allowing them to develop and manage applications without the need to build time-consuming development environments. Users using PaaS can also access various resources in the application stack, such as middleware, programming languages, operating systems, and databases.
[SaaS]
is called cloud application service, which is the most comprehensive form of cloud computing service. It provides the entire application managed by the provider through a web browser. SaaS is very suitable for small companies or companies that do not have the ability to develop their own software applications. Start-ups.
