other well-known Internet vendors have launched private cloud services in China. Many users have introduced public cloud technology to build their own industry clouds. By learning the business model of Internet service providers, customers in the financial sector rebuild and transform the application architecture and data architecture, and then adopt the network model for Internet data center in the technical architecture. Current commercially available private cloud solutions can only be used together with corresponding hardware devices. They are prone to bundling by vendors. When customers in the financial sector are building a cloud platform, it is an important for them to consider how to unbundle network devices, servers and other hardware and build a highly reliable private cloud platform.
The Spine-Leaf architecture without business zone is adopted for infrastructure network of financial cloud platform, and the traditional three-tier core-convergence-access architecture is abandoned. 10/40G networking is widely used in Underlay network. Business traffic, storage traffic and virtual machine management migration traffic are merged into a 10-gigabit physical grid. The device management network is independent. Unified Internet outlets and private network outlets are built. As computing, storage and Overlay nodes, the servers used are universal X86 servers. Most of them are rack mount, with high density and low cost.
Network decoupling: based on IP network software/hardware encapsulation tunnels, controllers adapt to network devices for decoupling the physical network from the logical one;
Easy scalability: only adaptation to the underlay network required, advantageous in Internet scenarios;
Cost-efficient: ports high-density and reusable to ensure high performance of underlay network transmission.
Financial clouds are primarily used for Internet access services. There are many financial services. Flexible, rapid infrastructure scalability and iteration are required to meet business needs; Cost efficiency must be considered for rapid scalability to ensure the competitiveness in the highly competitive financial market.
Deeply involved in people's livelihood, financial business requires high business stability. Any change to the architecture requires more consideration of business reliability. An excellent top-level architecture can solve reliability problems well.
Tight supervision of financial data is often a powerful obstacle to cloud. Backup, security and privacy should be considered for all data on the cloud, which is often contrary to the open concept of cloud native. Business and data reliability are one of required considerations for the architecture.
Unbundled from network device, server and storage vendors; it is only required that the network is accessible, servers support distributed computing and storage, and data centers support rapid service deployment and launch.
Construction costs are greatly reduced. The investment in security devices and special centralized storage is reduced. They are implemented with software.
It is provided for upper network management applications through APIs to manage network devices. Once the network is built, almost no change is required in the later period, and IT O&M is simple.
With in-depth partnerships with public cloud vendors, ECCOM provides many proven cases, architecture security and reliability.
