In the world of networking, connection speed and quality have always been the battleground for every information professional. Engineers strive tirelessly to minimize latency just to ensure users can quickly access their websites or app content. Especially when targeting users in China, it's common to encounter excessively high latency or even inability to connect.

Given such challenges, there are countless acceleration solutions available in the market. How does one choose the right acceleration solution for their business scenario?

Don't worry! We'll focus on two main axes:

1. Reducing connection latency
2. Connection solutions for Chinese users

We'll elaborate on the principles and deployment methods of EIP and CDN, organizing applicable scenarios, benefits, and cost comparisons to help engineers make informed decisions without the headache of acceleration solutions!

What is EIP? EIP stands for Elastic IP, which provides public internet connection IP addresses that can be attached to computing instances, enabling cloud machines to connect to the Internet.

So, what is Premium EIP? Also known as BGP (Multi-Line) Premium IP, it's still a type of EIP, but optimized for users within mainland China. This optimization accelerates connections for Chinese users when accessing computing instances attached to Premium EIP, reducing latency and packet loss.

Given this characteristic, Premium EIP is particularly suitable for expanding into the Chinese market, such as web pages and game operations. It can be deployed either by "setting up proxy servers" or "directly establishing servers." The former involves setting up reverse or forward proxies using Alibaba Cloud computing instances attached to Premium EIP to help users connect in or out, while the latter deploys services directly on servers attached to Premium EIP for accelerated service.

What is CDN? CDN stands for Content Delivery Network, which is divided into General CDN and Dynamic DCDN on Alibaba Cloud. The former caches and accelerates static content in web pages, including HTML, CSS, images, videos, etc. The latter optimizes routing for services, accelerating requests from edge nodes back to the origin.

Generally, if you aim to serve global users and accelerate website or game page loading, General CDN for static content acceleration is suitable. If you need to interact with the backend, such as fetching API data, database interactions, etc., Dynamic DCDN is recommended for routing acceleration optimization, ensuring quick return to the origin.

Additionally, it's important to note that if you intend to accelerate CDN for regions outside China, a regular domain is sufficient. However, for serving users in China, ensure the domain has undergone ICP filing. Only with filing approval can you provide content and services within China.

Below is a comparison of the two services, allowing you to choose the appropriate service based on your needs.

Furthermore, this article only compared the Premium EIP and CDN services. The next article will compare the CEN and GA services.
