When many customers start to use the cloud, they will simply use the cloud (server) as a common physical server, such as storing application systems, databases and files on the same cloud server. When there are more users, it is not convenient to expand the application capacity. It is also difficult to handle high concurrency requests simply by upgrading the specification. It is recommended to separate computing from storage. The cloud provides customers with more than just servers, but also many other cloud services, so that customers can do cloud architecture on the cloud, and ultimately bring high availability, flexibility and other advantages.
Elastic extension of architecture
Upgrade from a stand-alone manual deployment architecture to a cloud based fully hosted deployment architecture, so that the overall architecture has automatic elastic scalability, and can more flexibly respond to business access loads and high concurrency requests.
High availability of business
The active/standby architecture provided by the highly available form of RDS MySQL can support automatic database failover, with an SLA commitment of up to 99.99%, greatly improving the availability of the overall business and ensuring the continuous availability of the business.
