At present, under the huge impact of cloud computing on the traditional network environment, the IT model gradually presents three characteristics, namely, the large concentration of data, the statistical reuse of resources, and the distribution of services on demand.
In the management interface of the traditional network, the so-called "human-machine interface", the network configuration is generally not changed frequently, and after the business is allocated on demand, the traditional "human-machine" interaction mode continues to be used, and the efficiency will be reduced. Obviously, it cannot be satisfied. Therefore, a "machine-machine interface" is required to realize the efficient interaction between the cloud management platform (the so-called collaborative system) and the network. Based on the network status and challenges in the cloud era, cloud connectivity solutions emerge as the times require.
Cloud connection is used to meet the intelligent, elastic and visual cloud interconnection services of POP node-POP node, data center-public cloud, and public cloud-public cloud in different regions.
The cloud connection dedicated line can reconfigure resources at any time to meet changing needs and solve multi-service interconnection such as remote data transmission, disaster recovery, and backup.
Cloud Dedicated Line makes full use of the advantages of public cloud services, allowing the continued use of existing IT infrastructure to achieve a flexible, integrated and scalable hybrid cloud computing environment. Its advantages are:
1. High-performance, low-latency data transmission: high-speed, stable, and low-latency network transmission provides a better user experience.
2. High security and exclusive private network: Users can use multiple virtual interfaces and establish dedicated connections with multiple virtual interfaces while maintaining network isolation.
1. Disaster recovery in different places: establish backup systems in different locations and connect them through dedicated line services, so that when a disaster occurs, the system can be restored to normal more reliably and quickly.
2. Hybrid cloud architecture of enterprise data center: For banks and state-owned enterprises, due to security and control reasons, not all enterprise information can be placed on the public cloud. The hybrid cloud architecture can be used to keep key data in the local data center, and other data into the cloud.
It can be seen that it builds a hybrid cloud scenario of a virtual private cloud and an on-premises data center. At the same time, cloud disaster recovery, cloud hosting, and off-site backup can be established through the local data center. This kind of cloud private line access service is mostly due to the high requirements of banks and state-owned enterprises in terms of security and control, and it is also widely used for high-speed guarantee and network quality guarantee.
