Cloud computing services, first introduced by Amazon, were initially not well received due to high investment, low profitability, and security concerns. Today, ten years later, cloud computing has undoubtedly profoundly changed the IT industry, people's work and life, and the way companies operate. In its development, cloud computing has become an independent IT infrastructure service. IT infrastructure must maintain larger-scale coverage and lower cost control in the market's development, while also combining flexible and scientific sustainable management to provide convenient and reliable services for enterprises. Internet giants such as Google, IBM, Alibaba, Baidu, and Tencent have aimed at the development opportunities of the cloud computing market and invested a lot of energy to elevate cloud computing services to a strategic height in order to occupy a place in this rapidly growing market.

As the key to the development of cloud computing services, data centers are undergoing new changes under the drive of the times, and the hosted data center market is also growing. In the past, hosted data center providers improved the operational capabilities of hosted data centers by expanding space and power, but now this method is no longer applicable, and network connectivity is more critical. Network connectivity directly connects customers with business partners and provides security and efficiency guarantees.

Data center connectivity in the era of cloud computing is based on strong network coverage and provides extensive and flexible connection services. Content hosting connections connect enterprise customers with partners, customers, peer networks, and cloud computing inside the hosting facility, and achieve low-latency, high-speed exchange, and high-security data connections based on fiber cross-connections.

Value-added services such as disaster recovery, end-to-end Ethernet connections, network peering, and hybrid cloud deployment are becoming increasingly mature, and enterprise customers will have more choices. At the same time, the development of hosted data centers and cloud computing will also face more opportunities and challenges.
