摘要： A method, system and computer program product for performing maintenance operations on a cloud computing node. An administrative server receives an indication that a maintenance operation is to be performed on a cloud computing node. The administrative server identifies which virtual machine(s) on the cloud computing node will be affected by the maintenance operation. The administrative server relocates the virtual machine(s) to be affected by the maintenance operation to other suitable cloud computing node(s) prior to the maintenance operation being performed. The administrative server then performs the maintenance operation on the cloud computing node. The virtual machine(s) may be relocated back to the cloud computing node after the maintenance operation is completed in response to a need to rebalance resources in such a manner. In this manner, maintenance operations may be performed on a cloud computing node without requiring to stop all the virtual machines in the node.

摘要： A method, system and computer program product for dynamically building a set of compute nodes to host a user's workload. An administrative server receives workload definitions that include the types of workloads that are to be run in a cloud group as well as a number of instances of each workload the cloud group should support. These workload definitions are used to determine the virtual machine demands that the cloud group will place on the cloud environment. The administrative server further receives the demand constraints, placement constraints and license enforcement policies. The administrative server identifies a set of compute nodes to host the user's workload based on the virtual machines demands, the demand constraints, the placement constraints and the license enforcement policies. In this manner, a set of compute nodes is dynamically built for consideration in forming a cloud group without the user requiring knowledge of the cloud's composition.

摘要： The present invention discloses a system, method, apparatus, and computer usable product code for handling requests. The invention can include a kernel level cache, a request handling service, and a transport layer security service. The kernel level cache can store request handling data. The request handling service can handle secure requests at a transport layer of a kernel when request handling data is present in the kernel level cache. The transport layer security service can handle encryption/decryption operations for the secure requests and request responses at the transport layer.

摘要： Methods systems and computer program products for load balancing using Mobile Internet Protocol (IP) Version 6 are provided. A request for a connection is received from a client at a routing stack. A Mobile IP Version 6 Binding Update message is transmitted from the routing stack to the client responsive to the received request. The Binding Update message identifies a selected target stack so as to allow the client to communicate directly with the target stack bypassing the routing stack

摘要： Methods and systems for providing non-proxy Secure Sockets Layer and Transport Layer Security (SSL/TLS) support in a content-based load balancer are described. A Transmission Control Protocol (TCP) connection is accepted from a client, and an SSL/TLS connection is established with the client such that random data used in key generation is created. A request is received from the client, and the request is decrypted. The request is processed, a target stack is selected, and the TCP connection, the SSL/TLS connection, and the random data are transferred to the selected target stack such that the client and selected target stack maintain an end-to-end TCP connection with a non-proxy SSL/TLS connection.

摘要： An improved technique is disclosed for routing data across multiple topology subnets, and for improving the connectivity between nodes in multiple topology subnets, by using a common connection network. A new type of virtual node, referred to herein as a “global” virtual routing node or “GVRN”, is defined to represent connectivity to an underlying network that may extend beyond the boundaries of the topology subnets in the end-to-end path. This underlying network is also referred to as a “common connection network” or a “global connection network”. The present invention also defines novel techniques with which border nodes pass routing information between networks to convey connectivity to the GVRN. In many cases, use of GVRNs will result in shorter end-to-end data transmission paths.
