Infosys' Grid Application Engineering Framework
Migration of legacy applications to Grid is imperative for analytical, backend batch and data intensive applications to ensure high performance and throughput. Migration involves significant investments in terms of domain knowledge and judgment on application analysis and reengineering. The Grid Application Engineering Framework analyzes the application portfolio, profiles the code base for Grid enablement, and suggests the best possible way for migrating legacy applications to the Grid environment. The framework helps specialists take informed decisions during migration.

Infosys Grid-based Data Virtualization (Infosys GRADIENT)
This is an Enterprise Information Integration (EII) solution. It addresses challenges in enterprise data access and integration. It enables applications to access both raw and integrated data from multiple, heterogeneous, and distributed data sources, while concealing the complexity of disparate data sources. Rather than moving data or creating new stores of integrated data, the EII solution creates a federation of multiple existing data sources and provides a single, virtual data source through which applications can access data. EII creates a "data service" or "data veneer" that enables applications and end-users to treat multiple data sources as a single source of data.

Infosys' Grid Operating System (OS)
The Grid OS provides a virtual execution container for executing grid tasks, providing isolation and ensuring minimal performance loss due to enhanced capability to provision compute resources to grid tasks. By using a package repository to build custom virtual execution domains, it reduces instantiation time substantially and prevents unwanted services from operating in the virtual domain. Grid OS is a light weight operating system that offers the benefits of virtualization to the grid environment. Grid jobs are run on virtual machine instances rather than the physical server.

Infosys' Grid Workflow Manager
Applications in the Life Sciences, Energy and Finance sectors need the extensive computing resources that a Grid offers. Many applications require business level workflow definitions to interact with the underlying heterogeneous grid infrastructure, where jobs comprising the workflow can be distributed across the infrastructure. The Grid Workflow Manager allows users to submit jobs through the workflow. It provides an interface to specify relationships among different jobs to be submitted to the Grid infrastructure. The workflow allows the integration of applications with enterprise entities such as web services, multiple data sources and business processes. Virtualization and load balancing result in improved efficiency.

Infosys' Virtual Management Console
This console is a generic virtual machine management tool that seamlessly manages virtual machines created by different hyper-visors on different platforms. It simplifies management of virtual machines in a heterogeneous data center. The tool has a generic service interface for creating, managing and monitoring virtual machines, which may also be used for programmatic access to these virtual machines. As the standards for storing and accessing virtual machines evolve, this tool can leverage emerging standards to provide a feature-rich management platform.
