Shared instances of API Gateway will be upgraded to serverless instances in batches.
Serverless instances are shared among users, who do not need to purchase the instances. Serverless instances charge fees only for initiated calls based on the same prices as shared instances. Compared with shared instances, serverless instances provide dynamic elasticity and a 99.9% SLA guarantee.
Serverless instances are in canary release. For regions in which serverless instances are available, menu items related to shared instances are changed to serverless instances in the console. Shared instances are upgraded to serverless instances in hot upgrade mode, which does not affect API calls to the original shared instances.
Limit item | Serverless instance |
Maximum inbound requests per second (RPS) per group | 2,500 |
Maximum inbound connections per user in the same region | 100,000 connections per domain name |
Maximum size of an outbound connection pool | 2,000 |
Maximum inbound public bandwidth (Mbit/s) | 5,120 Mbit/s. The bandwidth is shared by multiple users, and no specific limit is imposed on each user. |
Maximum outbound public bandwidth (Mbit/s) | The bandwidth is shared by multiple users. Maximum outbound public bandwidth = Number of outbound IP addresses of serverless instances x 200 Mbit/s. |
SLA | 99.9% |
