Alibaba Cloud exclusive virtual host, lightweight application server and cloud server ECS configuration selection (beginner tutorial)

There are three types of models commonly used by Alibaba Cloud server users: dedicated virtual host, lightweight application server and cloud server ECS. Dedicated virtual host is the simplest, but relatively speaking, it also has many restrictions. If you are just building a website, You can choose this one. The lightweight application server supports one-stop domain name, website, security, operation and maintenance, application management and other services, simplifying the steps of building a PHP environment and website. Users can easily build their own website with the click of a mouse. On the contrary, Alibaba Cloud ECS server has higher requirements, and the personnel to be configured must be proficient in using the Linux environment and commands. Among them, the most purchased one is Alibaba Cloud Server ECS.

What is Alibaba Cloud Server ECS?

The cloud server (Elastic Compute Service, commonly known as ECS) is an IaaS (Infrastructure as a Service) level cloud computing service provided by Alibaba Cloud with extraordinary performance, stability, reliability, and scalability.

What can it be used for?

Cloud server ECS has a wide range of applications.

With the perfect cooperation of these services, the website opening speed can be greatly accelerated and the waiting time of users can be shortened.

For higher requirements, for example, for business scenarios that require massive information storage and offline computing, such as Hadoop distributed computing, massive log processing, and large database management, you can choose the Alibaba Cloud ECS large basic data type Case specification model family. The Internet big data case specification model family is suitable for customers in manufacturing industries who have Internet big data computing and storage analysis requirements, such as the IT industry, the financial industry, etc.

For AI applications such as deep learning and deep neural networks, you can choose to purchase GPU computing cases and build AI applications based on TensorFlow architecture. The GPU computing type is suitable for thin terminal device scenarios such as image processing, cloud space animation rendering on cloud game platforms, and cloud space animation rendering for AR/VR.
