All applications are migrating to the cloud or Kubernetes, but how about your databases? MySQL, PostgreSQL, Oracle, etc., and traditional databases support your application services so well, but you are still troubled with big data, data management, auto-scaling, query performance, or tenant issues. When these database issues encounter the cloud native transition, problems will escalate exponentially. Thanks to SphereEx's DBPlusEngine and the Apache Software Foundation's Top-Level project Apache ShardingSphere, we are focusing on these rising database issues and creating a distributed/sharding database system based on your existing monolithic databases. The possibilities bring significant value to system architecture and infrastructure, and with the lowest upgrade costs, you can build your sharding database system on any cloud. This talk will guide you through not only the possibilities that can be unlocked by going cloud-native, but also the pain points and solutions.
