Ant blockchain technology architecture
According to the characteristics of different industries and the differences in cost and safety compliance requirements, Ant Blockchain provides differentiated cloud computing services, which are divided into financial districts (referred to as “golden districts”) and non-golden districts, between the two areas Physical isolation.
Financial District: Applicable to financial industries that have strict requirements on business security, reliability, and regulatory compliance. The use of independent computer room clusters meets the financial regulatory requirements of one bank and three conferences; provides ultra-high-level security protection and supports disaster preparedness for three centers in two places. The products and services in the financial district are more strictly managed in terms of network control and access control, and the prices are usually higher.
Non-financial areas: suitable for non-financial industries that have higher demands for cost and access flexibility. The resources, storage, and services are easier to access (for example, through the public network), it is more convenient to build a hybrid deployment environment on and off the cloud, and the usage is flexible, which facilitates the rapid establishment of business services. The types of products and services are similar to those in the financial district, and the prices are more affordable.
According to the geographic location (city) where the data center is located, the financial or non-golden area is further divided into different regions. The internal network of servers in different regions is not connected, and the public network can only be used for network communication. The closer the distance, the smaller the network delay. You can choose different regions according to actual needs.
The following two types of networks are provided on the Ant Blockchain:
Classic network: IP addresses are uniformly allocated by the Ant blockchain, which is easy to configure and easy to use. It is suitable for users who have high requirements for ease of operation and need to use ECS quickly.
Private network: VPC (Virtual Private Cloud), which is a logically isolated private network, supports custom network topology and IP address, and can be connected through a dedicated line. Suitable for users who are familiar with network management.
In order to provide disaster tolerance in the same city, the Ant Blockchain provides multiple zones in the same area. Different available zones are distributed in physical areas where power and network are isolated from each other, which can realize intranet intercommunication and fault isolation between available zones. The same enterprise user can choose two availability zones in a region to improve the high availability of applications.
Environment refers to the general term for hardware, software, network equipment, and data necessary to complete software development and deployment. The resources between the environments are logically isolated, and each tenant can create different “environments (Workspace)” for their applications according to the needs of R&D and delivery, such as development environments and production environments. Each operator can assign different permissions to different environments.
In order to support high availability, the environment can cross the zone (Zone) but not across the zone (Region). In each environment, you need to purchase the corresponding resources for the application, and different environments can release different application versions.
