Grid Enabled Services Infrastructure (GESI)

Capabilities Briefing Transformation from the Global Information Grid (GIG) to Net-Centric Environment (NCE)

Background

Office of the Secretary of Defense for Networks & Information Integration (OSD NII) presented a roadmap for transformation of the Global Information Grid (GIG) to the Net-Centric Environment (NCE).

DoD NCE Grid Computing: The Net-Centric Environment (NCE) “grid” is envisioned as a federation of distributed computing resources available over local and wide area networks that appear to an end user or application as one large virtual computing system. NCE Grid Computing will be built on pervasive services

• riented internet standards which will allow the DoD to share

computing and information resources across departmental and

• rganizational boundaries in a secure, highly efficient manner.

Technology Enablers of the NCE

• Clustering: Collections of computers in a fixed configuration

designed to be operated and managed as a unified, high- performance machine.

• Server Virtualization: Provides the ability to deploy a

discrete number of “virtual machines” on a single hardware platform.

• Network Virtualization: Allows for the establishment of

Virtual LANs (VLANs) between Virtual Machines.

• Storage Virtualization: Pooling of physical storage from

multiple network storage devices into what appears to be a single storage device that is managed from a central console.

• Agile Infrastructure Framework: Providing a very agile

grid framework upon which to build a Service Oriented Architecture (SOA)

Technology

NCE will be based on business approaches and technology solutions.

GESI Layered Architecture

Layered Architecture GESI provides a flexible layered architecture

First and foremost, a loosely coupled architecture allows you to replace components,

• r change components,

without having to make reflective changes to other components in the architecture/systems.

GESI as a Service Oriented Infrastructure

GESI SOI

SOA Alliance’s components of a Service Oriented Infrastructure

[2] The Open Group, Service Oriented Infrastructure: Charter, 31 July, 2007 , http://www.opengroup.org/projects/soa-soi/uploads/40/14171/OG-SOI-Charter-v1-1.pdf

GESI is part of a Service Oriented Architecture Foundation

Infrastructure Architecture is part of the SOA Alliance's SOA Foundation

As the Open Group Architecture Framework (TOGAF) states, good enterprise architecture brings important business benefits: A more efficient IT operation: – Lower software development, support, and maintenance costs – Increased portability of applications – Improved interoperability and easier system and network management – Improved ability to address critical enterprise-wide issues like security – Easier upgrade and exchange of system components Better return on existing investment, reduced risk for future investment: – Reduced complexity in IT infrastructure – Maximum return on investment in existing IT infrastructure – The flexibility to make, buy, or out-source IT solutions – Reduced risk overall in new investment, and the costs of IT ownership Faster, simpler, and cheaper procurement: – Buying decisions are simpler, because the information governing procurement is readily available in a coherent plan. – The procurement process is faster - maximizing procurement speed and flexibility without sacrificing architectural coherence.

GESI provides the essential elements

• f a Service Oriented Infrastructure

SOI delivers bottom-line benefits to the enterprise. It provides the basis for greater IT automation which results in higher IT productivity and lower operational costs. SOA Practitioner's Guide, part 2

Service Oriented Infrastructure

Moving from a dedicated infrastructure to a dynamic infrastructure

Addresses all the aspects of the infrastructure – Networks, servers, data centers, and firewalls – Application infrastructure, security, monitoring, middleware, etc. Key elements – Life cycle support to manage the deployment of SOI components – Virtualization of infrastructure resources to SOI users – Service management to assure the SOI solution provides the required service characteristics Combines architecture building blocks and role-based portals – High reuse of common services – Reuse of infrastructure and foundational components – Reduction in time needed to deliver capabilities

Benefits of the GESI Solution

Improve performance, availability, and cost-effectiveness of compute- and data-intensive applications Run growing volume of complex, resource-intensive, high- performance computing jobs within existing distributed infrastructure Provision additional capacity dynamically as it becomes available, and failover gracefully around unavailable capacity, without interrupting jobs in progress Reduces total cost of ownership of ongoing information technology (IT) operations by making more efficient use of available computing , storage, and network capacity Postpone the need for deployment of additional capacity to support growing transaction loads Provision, scale, and reconfigure virtualized computing resources within a service-oriented environment
