Guidance for Proof of Concept Pilot (PDF Version Available) Recommended Practice: Developing and Implementing an Enterprise-wide ElectronicRecords Management (ERM) Proof of Concept Pilot A proof of concept pilot project is an opportunity to demonstrate the capabilities of Electronic Records Management (ERM) software on a small area and in a controlled manner. This document applies the principles and "best practices" of IT project management to a proof of concept demonstration pilot for ERM whose purpose is to assess whether the solution should be deployed agency-wide. Top of Page 1. The strategic focus of the President's Management Agenda Electronic Government (E-Gov) initiatives is to transform federal programs and services into high-quality and well-managed cross-agency solutions to deliver services across the Federal government. The final guidance document in this series will be a "lessons learned" paper from EPA's proof of concept ERM pilot as well as other agencies' implementation experience. 2. 3. Preliminary - 4. 5.

Institute For Enterprise Architecture Developments KML FAQ - Keyhole Markup Language What is KML? KML is a file format used to display geographic data in an Earth browser, such as Google Earth, Google Maps, and Google Maps for mobile. You can create KML files to pinpoint locations, add image overlays, and expose rich data in new ways. KML is an international standard maintained by the Open Geospatial Consortium, Inc. Who uses KML? The KML community is wide and varied, as you'll see when you visit the Google Earth community forum. How do I create KML files? There are three main tools for creating KML files. Google Earth. Once you have created one of these objects, right click on it in the "Places" pane, and select "Copy". Text editor. There are also many tools created by users in the Google Earth community. How do I open a KMZ file? KMZ files are compressed collections of one or more files for viewing in Google Earth. How do I create KML for astronomy data? KML can be used to represent astronomical data, and loaded into Google Sky or Microsoft's WorldWide Telescope. No.

Software-defined networking Software-defined networking (SDN) is an approach to computer networking that allows network administrators to manage network services through abstraction of lower-level functionality. This is done by decoupling the system that makes decisions about where traffic is sent (the control plane) from the underlying systems that forward traffic to the selected destination (the data plane). The inventors and vendors of these systems claim that this simplifies networking.[1] SDN requires some method for the control plane to communicate with the data plane. History[edit] One of the first and most notable SDN projects was AT&T's GeoPlex.[5] AT&T Labs Geoplex project members Michah Lerner, George Vanecek, Nino Vidovic, Dado Vrsalovic leveraged the network APIs and dynamic aspects of the Java language as a means to implement middleware networks. As noted, GeoPlex did not concern itself with operating systems running on networking hardware switches, and routers. Concept[edit] Inconsistent policies

OBASHI The OBASHI methodology provides a framework and method for capturing, illustrating and modeling the relationships, dependencies and dataflows between business and Information technology (IT) assets and resources in a business context. A Business and IT (B&IT) diagram built using the OBASHI Framework. It is a formal and structured way of communicating the logical and physical relationships and dependencies between IT assets and resources (Ownership, Business Processes, Applications, Systems, Hardware, and Infrastructure) to define the business services of a modern enterprise. The name OBASHI is a licensed trademark of OBASHI Ltd. Core Principle[edit] OBASHI is based around a core principle: that IT exists for one reason, namely, to manage the flow of data between business assets. Business resources (which include people) and IT assets are either providers of data, consumers of data or provide the conduit through which the data can flow. The Origins of OBASHI[edit] Characteristics[edit]

What is software-defined networking (SDN)? - Definition from WhatIs.com Software-defined networking (SDN) is an umbrella term encompassing several kinds of network technology aimed at making the network as agile and flexible as the virtualized server and storage infrastructure of the modern data center. The goal of SDN is to allow network engineers and administrators to respond quickly to changing business requirements. In a software-defined network, a network administrator can shape traffic from a centralized control console without having to touch individual switches, and can deliver services to wherever they are needed in the network, without regard to what specific devices a server or other hardware components are connected to. The key technologies for SDN implementation are functional separation, network virtualization and automation through programmability.

How to manage requirements within the Enterprise Architecture using the TOGAF® and SABSA® frameworks By Pascal de Koning, KPN You want to put your company’s business strategy into action. What’s the best way to accomplish this? This can be done in a structured manner by using an Enterprise Architecture Framework like TOGAF®. As the figure shows, Requirements Management plays a central role in the architecture work in the TOGAF® methodology. Unfortunately, TOGAF® does not offer guidance on Requirements Management. Business Attribute Profiling is a requirements engineering technique that translates business goals and drivers into requirements (see figure 2). Executive communication in non-ICT termsGrouping and structuring of requirements, keeping oversightTraceability mapping between business drivers, requirements and capabilities The BAP process decomposes the business goal into its core elements.

Scenario 3: VPC with Public and Private Subnets and Hardware VPN Access - Amazon Virtual Private Cloud The configuration for this scenario includes a virtual private cloud (VPC) with a public subnet and a private subnet, and a virtual private gateway to enable communication with your own network over an IPsec VPN tunnel. We recommend this scenario if you want to extend your network into the cloud and also directly access the Internet from your VPC. This scenario enables you to run a multi-tiered application with a scalable web front end in a public subnet, and to house your data in a private subnet that is connected to your network by an IPsec VPN connection. Configuration for Scenario 3 The following diagram shows the key components of the configuration for this scenario. Important For this scenario, the Amazon VPC Network Administrator Guide describes what your network administrator needs to do to configure the Amazon VPC customer gateway on your side of the VPN connection. Basic Configuration for Scenario 3 A virtual private cloud (VPC) of size /16 (example CIDR: 10.0.0.0/16). Tip Note

Useful mininet setups | SDN Hub Mininet is a network emulation platform that is very useful to test SDN applications that you build. It can support different types of topologies. Here we showcase three popular configurations that will be helpful for testing. 1. Single switch Following command spawns a single switch with 3 hosts attached to it. $ sudo mn --arp --topo single,3 --mac --switch ovsk --controller remote In the above command, there are some important keywords worth paying attention to: –mac: Auto set MAC addresses–arp: Populate static ARP entries of each host in each other–switch: ovsk refers to kernel mode OVS–controller: remote controller can take IP address and port number as options You can now perform ping between hosts h1 and h2 using command h1 ping h2. 2. Following command spawns two switches connected to each other with a link and has one host on each switch. $ sudo mn --topo linear --switch ovsk --controller remote 3. Following command spawns a switch that has 3 servers and 1 client connected to it.
