Project background
The original service system of a municipal finance bureau used a virtualization platform, and the data was stored on the centralized storage. The storage capacity was seriously insufficient, and the VM could not write new data.
The business system needs to do real-time data synchronization in the data center of the Finance Bureau and the municipal Big Data Bureau to better serve the open sharing of urban data.
Some data is overwritten due to a virtualization platform fault, which cannot be rectified by the original vendor.
The city's financial allocation could not be paid for more than two months due to the failure of the platform, and the Municipal Bureau faced great pressure.
Demand challenge
Use the old idle server equipment, urgently build the cloud platform, and complete the cloud platform construction within 10 days.
Providing distributed storage provides flexible scalability while protecting existing investments by reusing existing centralized storage.
Provides data migration services to migrate all VMS on the original VM platform to the new cloud platform to take over critical service systems.
Supports the intra-city active-active architecture to achieve cross-data center disaster recovery capability and avoid service outages.
Scheme characteristics
Based on UCloudStack cloud, quickly complete the emergency construction of cloud platform;
The platform provides data migration tools to help customers quickly recover services
The cloud platform supports intra-city hypermetro, does not rely on third-party synchronization tools, and automatically switches disaster recovery
Scheme value
Take orders to solve customers' urgent needs, and practice the value concept of "user first"
The platform is built in 5 days, all hosts are migrated in 1 day, and cross-platform services run normally in 1 week
Cross-data center online migration mechanism, effectively support users for critical data security considerations
RPO=0, RTO≈0, zero data loss
