Web Hosting Solution

Traffic fluctuations are unavoidable for websites. If traffic volume spikes during a certain period, customers may experience high latency. It is crucial to deploy an architecture that automatically scales in response to traffic volume changes to provide a consistently high performance service with minimized cost and effort.

This solution deploys websites and applications on an auto scaling architecture, allows automatic adjustment of the compute capacity in response to traffic fluctuations, and helps you maintain a balance between performance and cost with scaling rules. It provides high availability and fault tolerance by evenly distributing ECS instances across zones as the compute capacity is scaled, supports database scaling to meet increased data demands, and supports Redis caching across zones to ease the load on the database. In this solution, Auto Scaling adjusts the number of ECS instances to ensure optimal performance with minimized costs, ECS instances are deployed across two zones to ensure high application availability, and the ApsaraDB for Redis instance is deployed in multiple zones to provide data caching.
