20080270585 | META-CONTAINER FOR MODEL-BASED DISTRIBUTED APPLICATIONS - Abstracting communication with a plurality of containers. Each container encapsulates or hosts a module (e.g., a web service, a database, etc.) associated with a distributed application. A meta-container communicates with drivers that interface with each of the containers. The meta-container represents an abstraction and a virtualization of the containers in the hierarchy. Each container may also be a meta-container for other containers. The recursion and layered hierarchy provide flexible, extensible, and efficient management of the distributed application. | 10-30-2008 |
20090113407 | MANAGING SOFTWARE LIFECYCLE - The present invention extends to methods, systems, and computer program products for managing software lifecycle. Based on declarative models and knowledge of their interpretation, embodiments of the present invention facilitate lifecycle management for model-based software applications. Lifecycle models, such as, for example, lifecycle state machine models are stored in a shared repository such that executive services can determine how software application lifecycles are to be managed and transitioned. Software lifecycle activities can verify that a transition is possible and identify any errors preventing a lifecycle transition. Model-based error handling and error recovery mechanisms can be used to correct any identified errors. | 04-30-2009 |
20090113437 | TRANSLATING DECLARATIVE MODELS - The present invention extends to methods, systems, and computer program products for translating declarative models. Embodiments of the present invention facilitate processing declarative models to perform various operations on applications, such as, for example, application deployment, application updates, application control such as start and stop, application monitoring by instrumenting the applications to emit events, and so on. Declarative models of applications are processed and realized onto a target environment, after which they can be executed, controlled, and monitored. | 04-30-2009 |
20090113457 | PERFORMING REQUESTED COMMANDS FOR MODEL-BASED APPLICATIONS - The present invention extends to methods, systems, and computer program products for performing requested commands for model-based applications. Embodiments of the invention permit efficient implementation of operations for model-based applications. Since drivers that are to implement an operation request data for implementing the operation, embodiments significantly reduce the likelihood of superfluous data being exchanged between an executive service and drivers. Further, if an operation is interrupted before implementation is complete, the operation can be resumed without having to re-perform already completed portions of the operation. Additionally, a user can be regularly updated on the progress of their commands. | 04-30-2009 |

20120159523 | MULTI-TENANT, HIGH-DENSITY CONTAINER SERVICE FOR HOSTING STATEFUL AND STATELESS MIDDLEWARE COMPONENTS - A container service is capable of hosting large numbers of middleware components for multiple tenants. A central container manager controls a plurality of compute nodes. The central container manager receives middleware components from external devices or services and assigns the components to containers on one or more designated compute nodes. Each compute node has a container management agent and one or more containers. The container management agents activate and manage the appropriate number of containers to run the assigned middleware components. The container management agent assigns each container on its compute node a limited set of privileges to control access to shared resources. The central container manager and each node's container management agent monitor container load levels and dynamically adjust the placement of the middleware components to maintain balanced operation. The compute nodes are grouped into clusters based upon the type of middleware components hosted on each compute node. | 06-21-2012 |
20130160115 | SANDBOXING FOR MULTI-TENANCY - Systems and methods according to various embodiments disclose a worker process manager adapted to spawn one or more worker processes on a server and to load an application on each of the worker processes. The worker process manager is adapted to isolate the one or more worker processes from each other and to control resource usage by the worker processes. A resource manager is adapted to detect applications that overuse system resources. The worker process manager is adapted to isolate worker processes and to control resource usage using one or more of the following techniques: least-privilege execution, messaging isolation, credentials isolation, data isolation, network isolation, fair share resource usage, and managed runtime security. Heuristic algorithms are used to detect applications that frequently overuse system resources that are unchargeable and that cause system unresponsiveness. | 06-20-2013 |
