Domain name resolution for a hybrid cloud cluster

Abstract

Embodiments of the present invention provide a method, system and computer program product for domain name resolution for a hybrid cloud cluster. In an embodiment of the invention, a method for domain name resolution for a hybrid cloud cluster includes receiving a request for name resolution in a DNS name server proxy executing in memory of a host computer in a public cloud. Thereafter, it can be determined whether or not the request for name resolution implicates a domain name within an Intranet coupled to the proxy over a communications network. Finally, the request for name resolution can be resolved in a DNS name server disposed in the Intranet in response to determining the request to implicate a domain name within the Intranet. Otherwise, the request for name resolution can be resolved in a DNS name server for the public cloud in response to determining the request not to implicate a domain name within the Intranet.

Description

BACKGROUND OF THE INVENTION[0001]1. Field of the Invention[0002]The present invention relates to hybrid cloud cluster deployment and more particularly to domain name resolution in a hybrid cloud cluster.[0003]2. Description of the Related Art[0004]Network computing, at its core, relates to the transport of data between addressable computing endpoints in a network of computing endpoints. Integral to network computing is the universal way in which data is addressed so as to be delivered to an intended end point. In this regard, the Internet protocol (IP) is the principal communications protocol used for relaying packets of data across an internetwork using the IP suite. Responsible for routing packets across network boundaries, IP is the primary protocol that establishes the Internet. The domain name system, however, remains the enabler of global computing by bridging the complexity of the IP address with a human factors friendly domain name.[0005]The domain name system (DNS) is a hie...

Problems solved by technology

While the architecture and operation of the DNS has become a generally understood principal of computing in respect to the Internet, managing the DNS in a hybrid cloud computing environment is not without its challenges.

Also, the private enterprise name is typically not resolvable in the Internet, but only within the Intranet.

Thus, no one DNS name server can resolve both the internal names of the public cloud and also the internal names of the private enterprise.

First, only private enterprise names have been used, but two drawbacks result: (1) all connections within the cluster now must traverse the Internet, through at least two secure pipes, and an exceptional performance penalty results large enough to likely be completely unacceptable; and (2) some services and / or ports in the public cloud instance may be configured to only accept connections from inside the public cloud, or only from outside the private enterprise.

This course of action introduces possible errors and also performance penalties.
