Background and challenge
ZD information technology provides marketing software and services for global government enterprises, provides IaaS, and carries PaaS (data center) and SaaS (scenario-oriented intelligent marketing tool set) on top of it.
The use of full public cloud service model, the explosive growth of business, resulting in high public cloud costs.
Infrastructure maintenance costs are difficult to optimize.
Scheme characteristics
UCloudStack is used as the private cloud base, and the public cloud forms a hybrid cloud architecture, and gradually migrates services to UCloudStack.
After 3 years of gradual migration, it has now fully sunk from public cloud to private cloud environment.
From the initial 20 private cloud nodes, it has expanded to more than 200 nodes.
Scheme value
Infrastructure maintenance costs fell by more than 30 percent.
In the hybrid cloud mode, the cloud service experience is the same as that of the public cloud.
After the business sinking, under the premise of meeting its own business needs, it can also provide public cloud services, covering IaaS\PaaS\SaaS.
Based on the hybrid cloud architecture, the dual-data center data hypermetro architecture is implemented to further improve business continuity.
