A multi-tenant virtual machine infrastructure (MTVMI) allows multiple tenants to independently access and use a plurality of virtual computing resources via the Internet. Within the MTVMI, different tenants may define unique configurations of virtual computing resources and unique rules to govern the use of the virtual computing resources. The MTVMI may be configured to provide valuable services for tenants and users associated with the tenants.

Multitenant hosted virtual machine infrastructure

Method, medium, and system for multitenant hosted virtual machine infrastructure

A system and method for performing enhanced modeling of multi-tiered architectures is presented. The system and method enable selection of a preferred design for a multi-tiered architecture of components based on a set of established criteria, and may employ certain vectors and functions in component attributes, and such attributes may include scalability and scope of fault attributes.

Method and apparatus for enhanced design of multi-tier systems

An embodiment of monitoring resource usage in a computing environment begins with a first client registering a session with a monitoring entity. The session comprises an event type, a count, a start condition, an end condition, and a sample type. Next, a second client registers with the session. Upon occurrence of the start condition and until occurrence of the end condition or until interrupted, the monitoring entity iteratively initiates a counting of occurrences of the event type that continues until reaching the count and saves a sample according to the sample type upon reaching the count. The resource monitoring entity provides at least a portion of a plurality of samples to the first client.

Method of monitoring resource usage in computing environment

According to an embodiment, a method of sampling hardware events in a computer system comprises a first step and iterative performance of second and third steps. In the first step, an initiator virtual machine identifies a profiling event and a count to a virtual machine monitor. The virtual machine monitor iteratively performs the second and third steps. In the second step, the virtual machine monitor programs a hardware event counter with the count for the profiling event. In the third step, upon receiving an interrupt from the hardware event counter, the virtual machine monitor saves a sample that comprises a code-in-execution identifier.

Method of sampling hardware events in computer system

A system and method for selecting a preferred design for a multi-tiered architecture of components based on a set of established criteria is provided. The system and method receive a model describing different design constructions and a set of performance and availability requirements and produces a design or set of designs that best meet these requirements. The system and method include a model for representing the infrastructure design space for multi-tier systems and their properties appropriate for judging performance and availability properties of services as well as associated cost. The method and system further include a method for searching the design space in an efficient manner.

Selecting a target design based on criteria

A data center is designed by determining a compute description that describes computer resources to be used in the system from design requirements and models of the computer resources. A facility description that describes facilities to be used in the data center is determined from the compute description and models of the facilities. An integrated system describing the design of the data center is determined from the facility and compute descriptions.

Data center synthesis

A network controls congestion by monitoring how well packets are actually being received at their respective dataflow destinations. The destination nodes are outfitted with a monitor that returns an acknowledgement (ACK) datapacket to the source node for each reception. The return ACK datapackets are marked according to whether congestion was encountered in the delivery to the destination. If so, a rate limiter at the source node is signaled to slow down the data injection rate. If not, the rate limiter is signaled to dial up the injection rate. Several dataflows can be independently and simultaneously controlled this way.
