摘要:
This invention introduces a method, system and computer readable media that enables a computer system or computer networked system to perform enterprise portfolio transition optimization. The invention considers several key factors that are traditionally treated informally. The invention provides a sequential decision model for enterprise portfolio transition management of computer and software resources. Using a finite state Markov Decision process, a mathematical formulation is developed to ensure an optimal enterprise portfolio transition plan, with the objective of balancing expected value and risk, that is solved numerically via an approximate dynamic programming algorithm. The output of the model is a set of recommendations in the form of a transition plan for each of the computer and software resources selected within the enterprise portfolio during each phase of a planning horizon.

A method for managing a business. At least one relationship is determined between N business components (B1, B2, . . . , BN) and respective N costs (C1, C2, . . . , CN) and respective N values (V1, V2, . . . , VN) pertaining to the N business components. The N business components are a subset of M business components (B1, B2, . . . , BM) of a Component Based Model (CBM) of the M business components subject to M≧2 and N≦M. Determining the at least one relationship includes relating business components of the CBM with an Information Technology (IT) model of an IT system. The IT model includes abstract IT structures, virtual IT structures, real IT structures, or combinations thereof.

A service element is defined and represented by a data structure. It includes one or more components and/or one or more other service elements. A service element providing a complete function is a service offering. Management of service elements and/or service offerings is facilitated by a Service Development Tool. In different aspects, the management includes various tasks associated with creating, modifying and deleting service elements, establishing relationships, error checking and optimization. In a further aspect, service elements are packaged and distributed to enable customers to deliver the service elements. Additionally, the hosting of software packages is facilitated.

A firewall rule generation method, a load balancing rule generation method, and a wrapper generation method, for an Information Technology (IT) system, associated computer program products, and an associated processes for integrating computing infrastructure. The firewall rule generation method generates firewall rules allowing data transmission between a computer and a client, and subsequently assigns the firewall rules to firewalls of the IT system. The load balancing rule generation method assigns a load balancing mechanism to a load balanced group to which execution of an application is assigned, wherein the load balanced group has servers therein. For a client and computer having a communication protocol therebetween that is not allowed by a security policy, the wrapper generation method generates a communication protocol wrapper that opens a Transmission Control Protocol (TCP) connection between the client and the computer such that the TCP connection is allowed by the security policy.

A method and system for optimally scheduling an activity managed by a web application. Date and time ranges are initialized with predefined values. A tentative start date included in the date range and a tentative start time included in the time range are automatically calculated, and are included in a tentative schedule for the activity. A time period is determined by the tentative schedule and a duration of the activity. The automatic calculation prevents the time period from overlapping a time interval during which the web application is to experience a peak load. The tentative schedule is presented to the user via the interface, and is recalculated and redisplayed in response to the user updating a load-related parameter. The user selects a final schedule, which is the tentative schedule or a user-specified schedule different from the tentative schedule.

An Information Technology (IT) system display method and computer program product. A description is provided of a configuration of devices, network segments, and vertical connectors relating to an IT structure. The devices are initially distributed to form a distribution of the devices in a matrix representing a display screen. A defined goal value of the configuration is a function of a length and weight of each network segment, a length and weight of each vertical connector, and a penalty for each crossing of a device by a network segment. An overlay pattern of the network segments and the vertical connectors overlayed on the matrix is displayed in accordance with the description and the final distribution of the devices in the matrix. The goal value for the final distribution is lower than for the initial distribution. The final distribution is displayed on the display screen together with the overlay pattern.

A method and system for predicting a user activity level associated with an application. An activity level is a number of transactions performed by users utilizing the application per time period or a number of users utilizing the application per time period. Measurements of activity levels are assigned to a user activity metric (UAM) variable, and associated values are assigned to a set of factors. At least one correlation coefficient between each factor and the UAM is calculated. In response to a maximum correlation coefficient associated with a factor being less than a pre-defined threshold, the factor is excluded from the set of factors to facilitate forming a subset of factors associated with correlation coefficients whose absolute values are greater than or equal to the pre-defined threshold. A regression model utilizing the subset is generated to predict an activity level.

A method and system for porting an abstract Information Technology (IT) structure into an IT delivery environment. An abstract IT structure A that is currently within an IT delivery environment X is translated by generating a virtual IT structure V from the abstract IT structure A through specification of an IT delivery environment Y. Delivery binding the virtual IT structure V to the IT delivery environment Y generates a delivery-bound virtual IT structure D. The delivery-bound virtual IT structure D is deployed in the IT delivery environment Y, resulting in a real IT structure instance R capable of operating in the IT delivery environment Y.

A method for managing a cost of ownership of a portfolio of N software applications (N≧2). A regression function is identified for each application. Each regression function expresses an approximate cost of ownership of the applications in terms of parameters and coefficients. J applications A1, A2, . . . , AJ are selected from the N applications such that a remaining N−J applications are unselected (J 0). Σj represents a summation over j from j=1 to j=J. Wj are predetermined weights.

Method and system for verifying correctness of networking aspects of an Information Technology (IT) system that includes a host network of hosts. The hosts include servers and firewalls. A firewall connectivity indication of whether the host network includes an isolated firewall or a cross-zone connected firewall is determined. Determining for each host whether the host is isolated from a communication network to which the IT system is connected determines whether isolated network segments exit within the host network. For each host determined to be isolated from the communication network, the method identifies all network segments of the host network to which each host is connected, determines the unique network segments of the identified network segments, and designates the unique network segments as a set of isolated network segments. The firewall connectivity indication and the set of isolated network segments are stored in a storage medium of a computer system.
