As cloud computing matures, more and more enterprises are starting to build their own cloud resources on public clouds and use various cloud services. They tend to deploy cloud IT services on multiple public clouds. However, enterprises that choose different cloud services need to apply to the network provider and multiple cloud service providers independently for resources and maintain them independently. As there is neither unified and secure network management platform nor cloud resource management platform supporting multiple tenants, the application efficiency is low and the service deployment and maintenance is complicated. To solve these problems, enterprises are in urgent need for a solution that can manage multiple clouds efficiently and uniformly.
Trend for Operators to Build Cloud Access Platforms
Multi-cloud access has a broad market space. Leveraging their own network advantages to build cloud access platforms, telecom operators can provide better cloud access services for enterprises and facilitate the enterprises to manage multiple clouds more efficiently.
AT&T launched its NetBond early in 2013, providing network management and cloud infrastructure connection models for cloud service providers. Using the MPLS VPN technology, NetBond provides secure, flexible, high-performance connectivity for a customer. It can extend the customer's MPLS network from AT&T to any cloud service provider interconnected with the NetBond cloud system. The customer can also adjust network resources in real time. AT&T builds a complete cloud service provider ecosystem and has deep cooperation with Amazon, Microsoft, Google and Salesforce. Now more than 20 partner members provide cloud solutions.
Moreover, some third-party internet service providers (ISPs) offer multi-cloud access through VPN. China's VPN market has expanded from 4 billion RMB in 2010 to tens of billions RMB in 2018, and third-party ISPs occupy more than 50% of market share. Third-party ISPs are interconnected with multiple mainstream cloud service providers through high-speed fiber networks. Enterprise users can access multiple public clouds from any VPN node and deploy their cloud-based IT services.
Operators need to build a unified cloud-network service orchestration system to manage MAN, IPRAN, backbone network, POP node and cloud access center, and manage enterprise users' network resources on public clouds through the cloud API interfaces opened by public cloud service providers. Opening self-service portals to enterprise users based on the cloud-network service orchestration system enables enterprise users to rapidly and safely implement on-demand interworking between IDC and VPC, obtain PaaS/SaaS services, and perform unified management of multiple clouds, thus helping them complete digital transformation.
