On November 2nd, at the first “Eco Tools Special” event of the “Domestic Database Salon” series of live events held by Mo Tianlun, the senior product manager of Huawei Cloud DatabaseTeacher Hu YanjunShare”HUAWEI CLOUD GaussDB migration tool decryption“The keynote speech, this article is to organize the content.
(ChinaIT.com News) Data has always been an important asset for enterprises, and data-related content is still an important topic. The current economic situation at home and abroad and cloud computing have continuously promoted the development of domestic databases.Cloud and localized databases are the main directions at present. On the whole, domestic database companies are still in their infancy, and their development space continues to be promising.
Huawei’s overall database migration and management solution requires two tools:UGO(Database and Application Migration UGO, UGO for short)withDRS(Data Replication Service, DRS for short). UGO is responsible for grammar migration in database migration, and performs evaluation and conversion of heterogeneous databases. DRS performs data migration and data verification, and realizes real-time change data capture based on logs.
Huawei cloud database migration and management overall solution
01
UGO
UGO (Database and Application Migration UGO, referred to as UGO) is a professional cloud service focusing on heterogeneous database structure migration and application SQL conversion. Through UGO’s pre-migration evaluation and automated syntax conversion, it helps users identify migration risks in advance, improves migration efficiency, and minimizes users’ database migration costs.
Database and application migration UGO, throughTwo core functions of migration assessment and structure migration, To realize the automated migration of mainstream commercial databases to Huawei Cloud database, helpingRealize the purpose of one-click cloud access and one-click database switching.
UGO core components, execution process and technical architecture
The whole process is divided into two parts,The first part is the migration assessment, To help users understand the difficulty of the relocation process during the research phase,Thereby assessing the investment in migration.
The second part starts the migration implementation, Through the object filtering, grammar conversion, object correction, verification online, and finally transferred to the target database. In this process, cyclic correction and continuous verification can be realized. The later UGO planning enhances the direction in terms of accuracy, width and breadth.

DRS
DRS (Data Replication Service, referred to as DRS) can ensure that the database does not affect the business during the migration, allowing customers to achieve “reassurance”, “reason of worry”, and “confidence”.
-
Peace of mind
Advanced incremental data synchronization technology realizes the continuous relocation of the database during the business process,Migration does not affect business -
Worry free
Tens of thousands of cases are refined, hundreds of inspections automatically identify problems,Everyone can migrate well -
confidence
Provide data comparison, trial operation on business traffic cloud,Cloud data and performance can be known in advance
DRS technology principle
Data comparison is a big problem, you need to know accuratelyConsistency of data migration. Long downtime can achieve accurate comparison, but it will lead to business stagnation and “put the cart before the horse”.How to solve this industry problem?
HUAWEI CLOUD’s rapid comparison algorithm based on Merkel numbers makes waiting for results no longer long.
