A scalable cloud infrastructure serves two or more customers, where each customer is associated with at least one unit of virtual resources. The virtual resources are established by apportioning physical resources in the cloud infrastructure that are partitioned into pods within one or more zones in a scalable manner. Additionally, the cloud infrastructure establishes one or more management server clusters each comprising one or more management servers. The two or more customers create a number of virtual machines within pods in a zone. Due to the scalability of the cloud infrastructure, a console proxy virtual machine and server is introduced to support console access to virtual machines. The console proxy server serves as an intermediary between a browser and a viewed virtual machine configured to maintain viewing session quality while minimizing network impact.

Remote console access in a scalable cloud computing environment

A scalable cloud infrastructure serves two or more customers, where each customer is associated with at least one unit of virtual resources. The virtual resources are established by apportioning physical resources in the cloud infrastructure that are partitioned into pods within one or more zones in a scalable manner. Additionally, the cloud infrastructure establishes one or more management server clusters each comprising one or more management servers. The two or more customers create a number of virtual machines within pods in a zone. Due to the scalability of the cloud infrastructure, customer virtual machines may exist in non optimal locations within the zone. A method to migrate virtual machines and defragment customer networks is devised to optimally manage network traffic and data communication in a scaled cloud infrastructure.

Network fragmentation and virtual machine migration in a scalable cloud computing environment

A scalable cloud infrastructure serves two or more customers, where each customer is associated with at least one unit of virtual resources. The virtual resources are established by apportioning physical resources in the cloud infrastructure that are partitioned into pods within one or more zones in a scalable manner. Additionally, the cloud infrastructure establishes one or more management server clusters each comprising one or more management servers. The two or more customers create a number of virtual machines within pods in one or more zones. As customers interact primarily with the management server cluster to manage their virtual machine, a state and event handling method is devised to centralize the management of a potentially vast number of customer and supporting system virtual machines.

Event and state management in a scalable cloud computing environment

A scalable cloud infrastructure serves two or more customers, where each customer is associated with at least one unit of virtual resources. The virtual resources are established by apportioning physical resources in the cloud infrastructure that are partitioned into pods within one or more zones in a scalable manner. Each pod comprises a strongly connected discrete set of physical resources in a zone. Additionally, the cloud infrastructure establishes one or more management server clusters each comprising one or more management servers. Each management server is configured for allocating the units of virtual resources to an account associated with each customer. The traffic from two or more customer accounts within the scalable cloud infrastructure is isolated and segmented.
