Managing access to cloud-hosted applications using domain name resolution

A system comprising:

• a cloud computing platform comprising a plurality of regional clouds connected by a cloud backbone network, each regional cloud comprising a plurality of computing devices associated with a geographic region and connected by a regional network, the plurality of regional clouds being further connected to a wide area network (WAN) that does not include the cloud backbone network;
• a plurality of edge clusters on the cloud computing platform, each edge cluster being located in a different regional cloud of the plurality of regional clouds;
• and
• an intelligent routing module coupled to the plurality of edge clusters and programmed to:
• invoke instantiation of an application instance in a first regional cloud of the plurality of regional clouds having a first edge cluster of the plurality of edge clusters executing in the first regional cloud, the first edge cluster having a first internet protocol (IP) address;
• configure the first edge cluster to control access to the application instance;
• and
• program domain name resolution logic of the cloud computing platform to manage latency of requests to access the application instance from locations in multiple regional clouds of the plurality of regional clouds;
• configuring, by the intelligent routing module, one or more edge clusters of the plurality of edge clusters with alternative routing logic such that the intelligent routing module, the first edge cluster, and a second edge cluster of the plurality of edge clusters are configured to perform a method including:
• resolving, by the intelligent routing module, a domain of the application instance to a second IP address of the second edge cluster;
• receiving, by the second edge cluster, a request to access the application instance, the request addressed to the second IP address;
• routing, by the second edge cluster, the request to the first IP address according to the alternative routing logic.
