DB Instances
Before creating a migration project, you need to create a Huawei Cloud database as the target database.
Currently, UGO supports GaussDB, TaurusDB, RDS for MySQL, and RDS for PostgreSQL.
GaussDB
GaussDB is an enterprise-grade distributed relational database from Huawei. It features Hybrid Transactional/Analytical Processing (HTAP) workloads and intra-city cross-AZ deployment with zero data loss. With a distributed architecture, GaussDB supports petabytes of storage and more than 1,000 nodes per DB instance.
You can buy a GaussDB instance.
TaurusDB
TaurusDB is an enterprise-grade distributed database and fully compatible with MySQL. It uses a decoupled compute and storage architecture and data functions virtualization (DFV) storage that auto-scales up to 128 TB per DB instance. There is no need to do sharding and there is virtually no risk of data loss. It combines the high availability and performance of commercial databases with the cost-effectiveness of open source databases.
You can buy a TaurusDB instance.
RDS for MySQL
MySQL is one of the world's most popular open-source relational databases. It works with a LAMP stack (Linux, Apache, and Perl/PHP/Python) to deliver efficient web solutions. RDS for MySQL is reliable, secure, scalable, inexpensive, and easy to manage.
You can buy an RDS for MySQL instance.
RDS for PostgreSQL
PostgreSQL is an open source object-relational database management system focused on extensibility and standards compliance. It is known as the most advanced open source database. RDS for PostgreSQL is designed for enterprise-oriented online transaction processing (OLTP) scenarios and supports NoSQL (JSON, XML, or hstore) and GIS data types. It has earned a reputation for reliability and data integrity, and is suitable for websites, location-based applications, and complex data object processing.
You can buy an RDS for PostgreSQL instance.
