Over the past decade, data center services have shifted from predominantly web-centric to cloud-centric. Today, they are shifting once again, this time from the era of cloud computing and into the intelligent era. With massive amounts of data generated during digitalization, filtering out and automatically reorganizing useful information -- then mining the valuable data using Artificial Intelligence (AI) -- is arguably the key to the intelligent era. According to the Huawei Global Industry Vision (GIV), 97% of large enterprises will use AI by 2025. Indeed, more and more enterprises regard AI as the primary strategy for digital transformation.
