This topic describes FAQ about physical connection construction:

1. How long does it take to apply for and build an exclusive physical connection to connect to Alibaba Cloud?

The period varies, depending on the location of the on-premises data center and the access point of Alibaba Cloud.

  • The on-premises data center and the Alibaba Cloud access points are not located in the same building, and are connected through physical optical fibers. The construction period to connect the on-premises data center to the Alibaba Cloud service provider depends on the time consumed for laying cables. The overall period is three to six months.
  • The on-premises data center and Alibaba Cloud access points are located in the same data center and connected by an indoor cable. The overall period is within two weeks.

For more information, see Process of creating a dedicated physical connection.

2. In addition to applying for an exclusive physical connection, what other methods can be used to connect to Alibaba Cloud?

You can use the following methods to connect to Alibaba Cloud:

  • Apply for an exclusive physical connection from a service provider.
  • Choose a shared physical connection from Alibaba Cloud partners.
  • Alibaba Cloud managed products.

For more information about how to select a solution, see Physical connection solutions.

3. How long does it take to build a shared physical connection between the on-premises data center and Alibaba Cloud?

If the access point of your service provider has been connected to the access point of Alibaba Cloud, you can consult the service provider and require the service provider to connect your on-premises data center to Alibaba Cloud through the access point of the service provider.

The service provider only deploys the leased line from the on-premises to the access point of the service provider. The overall construction period is within one month. For more information, see Establish a shared physical connection.

4. What is the difference between an exclusive physical connection and a shared physical connection?

The main differences between applying for an exclusive physical connection and a shared physical connection are the payment methods and construction cycles:

  • You must settle payments to multiple related service providers for an exclusive physical connection and the construction period is 3 to 6 months.
  • You only need to pay the required fees to the service provider for a shared physical connection. The construction period is within one month.

For more information, see Physical connection solutions.

5. Why must a site survey be performed by a service provider when I apply for a physical connection to Alibaba Cloud?

The fees for a physical connection are determined by the physical distance between the on-premises data center and access points of Alibaba Cloud. The connection environments provided by the service providers are different. Therefore, the service provider must perform an end-to-end site survey before cable purchase.

After a site survey, the service provider offers you the information about the distance, lease fees, and construction cycle of the leased line. You will also see a description of each cable and its cost at the Alibaba access points and indoor cables of the on-premises data center. You can prepare the project planning and budget in advance based on the survey report.

6. How can I choose the service provider when I purchase an exclusive physical connection?

If you want to connect to Alibaba Cloud from the access point nearest to your location, you can find the access point on the buy page and choose the corresponding service provider. Different access points are supported by different service providers. For more information about the mappings between access points and the service providers, see Before you begin.

7. If I purchase an exclusive physical connection from China Mobile, can the on-premises data center be connected to an access point of China Telecom?

No. China Mobile, China Unicom, and China Telecom are mutually exclusive. They do not support an exclusive physical connection with other service providers.

8. Can a bare fiber be used to connect an on-premises data center to the access point of China Mobile?

China Mobile, China Unicom, and China Telecom do not support bare fiber to connect to on-premises data centers. Consult your service provider for details.

9. Why are fees charged for indoor cables of Alibaba Cloud access points?

The data centers of the access points in the China (Hangzhou)-Yuhang-A and China (Zhangjiakou) region are owned by Alibaba Cloud. The other data centers are leased from service providers or third-party data centers.

If you apply for an exclusive physical connection to connect your on-premises data center to Alibaba Cloud, you must purchase additional indoor cables from the data center provider.

10. What are the costs of applying for an exclusive physical connection to Alibaba Cloud?

An exclusive physical connection includes the following fees:

  • Alibaba Cloud only charges you a one-time initial installation fee, resource occupation fee, and outbound traffic fee.
  • You must pay the leased line rental fee to the carrier.
  • You must pay the indoor cable fee of the data center where the Alibaba Cloud access point is located from the data center provider.
  • You must pay the cost of the indoor cables of the on-premises data center to the data center provider.

11. What are the costs of a shared physical connection to Alibaba Cloud?

A shared physical connection includes the following fees:

  • Alibaba Cloud does not charge you any initial installation fee and resource occupation fee, but charges you an outbound traffic fee.
  • You must pay the leased line rental fee to the service provider.
  • You must pay the cost of the indoor cables of the on-premises data center to the data center provider.

For more information, see Billing of physical connections.

12. Apart from a letter of authorization (LOA) issued by Alibaba Cloud, why do I need an LOA issued by the service provider for construction in the on-premises data center?

The data centers of the access points in the China(Hangzhou)-Yuhang-A and China (Zhangjiakou) region are owned by Alibaba Cloud, while the other data centers are leased from service providers or third-party data centers. When you enter the facilities for construction, you must comply with the rules of both Alibaba and service providers.

Data centers of access points in Beijing and Shanghai belong to China Telecom and China Unicom. You must apply for an LOA for construction and provide the LOA to the on-site manager of the service provider at the on-premises data center for verification.

The letter of authorization must be stamped and certified by Alibaba Cloud. To apply for the seal of Alibaba Cloud, submit a ticket.

13. How can I choose a qualified physical connection in China?

According to stipulations of Chinese law, qualified leased line service providers must be granted both the A26 and A14 licenses issued by the Ministry of Industry and Information Technology of the People's Republic of China. Before you purchase a leased line, you can consult a service provider.
