Small and medium-sized enterprises (SMEs) tend to adopt simple deployment models when migrating applications to the cloud. For example, they may choose to deploy the entire environment on a single server to quickly set up an application. This single-server deployment is straightforward to implement but does not allow component isolation and is not horizontally scalable. In the longer term, the deployment may not be able to match business demand.

Alibaba Cloud makes it easy for SMEs to transform a single-server deployment and take advantage of cloud computing, including separate application and database servers, reverse proxy load balancing, Redis caching, accelerated content delivery, and auto scaling. You can add a separate database server to a single-server deployment to avoid resource competition between the database and the application. You can create a duplicate of the existing application server and achieve load balancing between the new and existing application servers.
