A system and method for managing power in virtualized computer systems are disclosed. In accordance with one embodiment, a request to instantiate a virtual machine is received. A processor determines whether a power state is to be altered to instantiate the virtual machine on a computing system, and in response to the determination, alters the power state.

Cloud management with power management support

A system and method for managing power in virtualized computer systems are disclosed. In accordance with one embodiment, a request to instantiate a virtual machine is received. A processor determines that a power state is to be altered to instantiate the virtual machine on a computing system, and in response to the determination, alters the power state.

A cloud management system can maintain a set of 'virtual groups,' and assign different 'virtual groups' to particular computing resources. The &#x201c;virtual groups&#x201d; can be based on the particular usage (type of virtual machine, application of the virtual machine, function of the virtual machine, and the like) of the members in the groups and/or can be based on the specifications of the computing resources (type and amount of computing resources). When instantiating virtual machines in a cloud, the cloud management system can utilize the &#x201c;virtual groups&#x201d; to identify and allocate the computing resources.

Flexible cloud management

A provisioning server can be configured to include a network configuration module that can set-up, configure, and manage network connections served by the provisioning server including name servers, such as Domain Name System (DNS) servers, in the network connections. The provisioning server can be configured to maintain a set of network modules, each network module corresponding to a different type of name server. Each of the network modules can be configured to include logic for generating or altering a configuration file for the corresponding type of name server.

Supporting multiple name servers in a software provisioning environment

Embodiments of the present teachings relate to systems and methods for generating modular security delegates for application instances, including, for example, applications usable on physical machines, virtualized environments, in the cloud, etc. According to embodiments, in a multiple network environment, multiple machines (or clients) can be configured, each having a defined security level. Each machine can include a plurality of application instances and corresponding security delegates for various defined security levels. For example, the defined security levels can be based on various authentication mechanisms, including, Kerberos, NT Lan Manager (NTLM) authentication protocol, secure sockets layer/transport security layer (SSL/TSL), token authentication, virtual private network (VPN), remote access security (RAS), digest authentication, etc.

Generating modular security delegates for applications

A cloud management system can determine if the operational state of the virtual machines and/or the computing systems needs to be altered in order to instantiate virtual machines. If the operational state of the computing systems needs to be altered, the cloud management system retrieves an identification of the power management systems supporting the computing systems. The cloud management system can utilize the identification of the power management systems to instruct the power management systems to alter the power state of the computing system in order to instantiate the virtual machines.

Flexible cloud management with power management support

Embodiments of the present teachings relate to systems and methods for generating modular security delegates for applications. According to embodiments, in a multiple network environment, multiple machines (or clients) can be configured. Each machine can include a plurality of application instances and an authentication delegate. In addition, each network environment can include a communication interface to security services. The applications can include logic that indicates what security delegate to use for a given set of user authentication credentials. The logic can be configured to determine the appropriate authentication delegate using various methods. The authentication delegates can receive a set of user authentication credentials from application instances and determine whether the set of user authentication credentials are valid. Each authentication delegate corresponds to one and only one type of authentication mechanism.

A cloud management system can maintain a set of 'virtual groups,' and assign different 'virtual groups' to particular computing resources of both local and external clouds. The &#x201c;virtual groups&#x201d; can be based on the particular usage (type of virtual machine, application of the virtual machine, function of the virtual machine, and the like) of the members in the groups and/or can be based on the specifications of the computing resources (type and amount of computing resources). When instantiating virtual machines in local or external clouds, the cloud management system can utilize the &#x201c;virtual groups&#x201d; to identify and allocate the computing resources.

Flexible cloud management including external clouds

In accordance with some aspects of the present disclosure, a method is disclosed that can include receiving, by a security delegate module, a set of user authentication credentials by an application running a first instance in a network for a user; determining, by the security delegate module, a type of the application; and selecting, by the security delegate module, a security service based on the set of user authentication credentials and the type of application.

Systems and methods for a security delegate module to select appropriate security services for web applications

A provisioning server can manage and configure the network parameters for target machines and systems residing in the networks associated with the provisioning server. The provisioning server can associate provisioning objects with the network configurations stored in the network record. The provisioning server can maintain an object record that associates the network configurations with different provisioning object. The provisioning server can utilize the object record to determine network parameters for target machines requesting provisioning processes, such as target machine installs, and virtualization.

Methods and systems for managing network connections associated with provisioning objects in a software provisioning environment

A provisioning server can manage network connections in the software provisioning environment. The provisioning server can maintain a network record of network configurations for the networks served by the provisioning server. The network record can include information describing the structure, hardware, software, and configuration of the networks served by the provisioning server. The provisioning server can manage and configure existing networks and instantiate new networks or sub-networks associated with the provisioning server. The network configuration module can retrieve the network configurations maintained in the network record to manage, configure, and instantiate existing or new networks.
