choose the right region for business deployment to meet network latency requirements
To meet the network latency requirements for your business deployment, you must choose the right region. This involves analyzing network quality data and product capabilities, considering the geographic distribution of your users, and understanding your business's network quality requirements. You should deploy core nodes in regions that are close to your users.
Priority
High
Practices to Avoid
Ignoring geographic distance: Avoid deploying core applications in regions that are far from your main user base. For example, if European users access nodes in the Asia-Pacific region, the one-way latency can exceed 100 ms.
Disregarding network topology: Avoid designs that fail to use the advantages of direct backbone network connections. This can cause traffic to take a longer path. For example, a link between North America and Asia might use a non-optimal path.
Using a single-region deployment: Avoid using only a single region for your deployment because it provides no redundancy. A sudden increase in traffic can overload a single node and cause latency to spike.
Expected Outcome
Region selection is optimized. Key business nodes are deployed in regions close to users. Cross-region traffic uses direct backbone network connections, such as Alibaba Cloud Global Interconnect.
Implementation Guide
User distribution and latency baseline: Analyze the geographic distribution of your users (for example, 70% of users are in the China East 1 region) and define a target latency threshold.
Network resource assessment: Use the Internet access performance observation feature of the NIS product to evaluate which Alibaba Cloud regions are suitable for your business deployment.
Product resource assessment: Check whether your candidate regions meet your business's deployment requirements, including product capabilities and resource Inventory.
Network resource access testing: Build a test platform and use network probe tools to verify access from different target customer regions. Use the results to determine the final region for your business deployment.
