Region and AZ Selection

When selecting a region and AZ, take the following into consideration:

• The geographic locations of CKafka instances, your business, and your target users:
  We recommend you choose the region closest to your end users when purchasing CKafka instances to minimize access latency and improve access speed.
• Relationship between CKafka and other Tencent Cloud services:
  When you select other Tencent Cloud services, we recommend you try to locate them all in the same region and AZ to allow them to communicate with each other through the private network, reducing access latency and increasing access speed.
• High availability and disaster recovery.
  Even if you have just one VPC, we still recommend you deploy your businesses in different AZs to prevent a single point of failure and enable cross-AZ disaster recovery.
• There may be network latency among different AZs. We recommend you assess your business requirements and find the optimal balance between high availability and low latency.
• If you need access to CKafka instances in other countries or regions, we recommend you select an instance in those other countries or regions. If you use a CKafka instance in China to access servers in other countries and regions, you may encounter a high higher network latency.
