API Gateway:General issues

To what scenarios is API Gateway applicable and what does it do?

API Gateway exposes applications deployed on Elastic Compute Service (ECS) or Container Service for Kubernetes (ACK) instances as APIs.

Can I delete the Alibaba Cloud Marketplace app?

No.

Can I use a security service or a Server Load Balance (SLB) instance together with API Gateway?

API Gateway handles security for you by default, so you do not need to attach a separate security service. API Gateway also scales resources automatically based on your business load, so you do not need an SLB instance for load balancing at the gateway level. However, if your backend service runs on multiple servers, you can use an SLB instance to balance loads among them.

Can I sign the service agreement online? How do I sign an offline agreement?

Yes. The online agreement is provided when you activate the service.

For an offline agreement, contact the API Gateway product manager and legal team.

Can I upgrade or downgrade my instance and how do I do that?

Yes. For more information, see Change an instance specification.

Does the egress of my virtual private cloud (VPC) integration instance change?

Yes. The egress address changes when you upgrade or downgrade your instance specification.

What are the management features in the console and how do I manage my resources?

The console lets you create, manage, and publish APIs. You can also manage API authorizations and traffic control.

What are the requirements for me to access API Gateway from a VPC?

API Gateway must be able to communicate with your backend services. Use Elastic IP Addresses (EIPs) or SLB instances to make your backend services accessible to API Gateway.
