Tiered Electronic Distribution (TED) • What is TED? 4 Overview 4 TED components 4 Flow through the components 4 What’s new 4 TED features 4 NAL and TED, Why do they need each other? • NAL Application Distribution features
What Is TED? Overview • Tiered Electronic Distribution, or TED, enables you to automatically deploy applications, software updates, system patches, and data files to your enterprise servers without leaving your desk 4 ZENworks for Servers uses TED to automatically distribute software and data files to Net. Ware, Windows NT/2000, Solaris and Linux servers throughout your network and is designed for optimal management efficiency, which allows you can schedule distributions for off-peak hours to minimize the impact on overall network performance 4 Some of these servers host TED components such as distributors and subscribers that are used for more effective software distribution
What Is TED? Components • TED is comprised of four logical components 4 Distributor 4 Distributions 4 Subscribers 4 Channels
What Is TED? Components • A Distributor builds a distribution from the information you provide • A Distribution contains a list of data packages or data grouping information Compilation of software and/or files, or a policy package 4 Distribution types 4 • File, FTP, HTTP, RPM*, NAL Application, Policy Package*, Software Package * New
What Is TED? Components • A Subscriber is a server that receives and extracts Distributions 4 Any server where you want to distribute applications, files, or policy packages must be a Subscriber • An External Subscriber is an object that represents a Subscriber in another tree • A Channel contains a list of Distributions associated with it and Subscribers that are subscribed to it
What Is TED? Flow through the Components Distributor • A Windows 2000 Subscriber could receive service pack distributions for Microsoft Back. Office by subscribing to a “Back. Office” Channel • This and another Subscriber might both use an “Anti. Virus” Channel to receive data specifically for Anti. Virus updates • Again, the Distributor is the crucial component that gathers, packages, and sends the distributions Back. Office update distribution Anti-virus Update distribution “Back. Office” channel “Anti-Virus” channel Back. Office Server (subscriber) File Server (subscriber)
What Is New • Supports the following platforms 4 4 Net. Ware 5. 1 and Net. Ware 6 Windows NT 4. 0 and Windows 2000 Linux (Red Hat 7 and above) Solaris 8 • Server Inventory and Remote control 4 Net. Ware, NT/2000 platforms only • TED and Policies will now be referred to as PDS (Policy and Distribution Services)
What Is New TED Enhancements • New TED Startup commands • Distribution patching 4 Removed 4 Send Queue and I/O Rate • New distribution types • Prioritizing distributions • Distribution security • File type distributions • Backwards compatibility with TED 2 • NAL application distribution 4 No more Site Distribution object • • • Windows NT/2000 support Linux/UNIX support New platform restrictions Cluster support DNS and NAT support Downstream schedule control 4 Parents Subscribers • Linking the Gather and Send processes • Distribution space limitation 4 Amount of disk space that you require to be free above the size of any Distribution
What Is New Web-Based Management 4 Zf. S 3 adds web management via Novell i. Manager 4 You can manage • • Distributors Subscribers Distributions Policies
TED Features WAN Optimization Features • Distribution hierarchies (parent subscribers) 4 4 Allows multiple-level distribution Enterprise-to-Region-to-District-to-Site • Compression 4 4 Compresses distributions before sending Uses less bandwidth for larger distributions • Scheduling 4 4 Controls when TED actions occur so data transmission occurs exactly when it is needed, or during off hours to reduce WAN traffic Send stops at the end of the time window and resumes when schedule allows • Checkpoint/Restart 4 Restarts interrupted distributions at the point of failure, does not require a complete resend
TED Features WAN Optimization Features • Throttling 4 On distributors to aggregate outbound flow 4 On subscribers for inbound flow 4 Prevents software distribution from dominating a WAN link and slowing network service 4 I/O Rate • Sending and receiving distributions • You can set the maximum bytes per second 4 Maximum Number of Concurrent Distributions • how many simultaneous distributions the Distributor Agent or Subscriber Agent will send 4 Send Queue • You can prioritize the order distributions are sent – High, medium, or low
TED Features WAN Optimization Features Parent Subscribers • Parent subscribers Reduce bandwidth utilization across WAN links 4 Acts as a proxy 4 Redistribute as they receive distributions, so next-level subscribers receive at virtually the same time as their parent subscriber 4
TED Architecture onsole. One Web Console 1—Distributor reads e. Directory to find distribution and package build schedules Distributor 2—When a build schedule comes due, Distributor gathers and compresses the distribution package e. Directory 3—When a send schedule comes due, Distributor sends distribution with a certificate All DB information is logged by Distributor 4—If the distribution certificate is valid, the subscriber accepts the distribution Subscriber returns status info to distributor Database Server When a subscriber is first configured to receive a distribution through a channel, Console. One can copy the distributor’s public key to the Subscriber 5—If the distribution is a Zf. D Application, Subscriber sends a “Create Application Object” work order to the Distributor; Subscriber makes no e. Directory calls
Summary of TED • TED provides a data distribution solution for the enterprise 4 Extensively scalable 4 Multiplatform 4 Extremely WAN-efficient • • • Tiered Secured Compressed Scheduled I/O throttled Resumed by checkpoint restart
NAL and TED—Why Do They Need Each Other? • Enables application management for the Enterprise • One application can act as master control for all sites • Changes are pushed to all sites • It reduces work Field offices
NAL and TED—Why Do They Need Each Other? • Zf. D can use TED to distribute application objects to other locations in the same tree or other trees—the distribution includes copying the original files associated with the applications to the appropriate server locations, where they can be used to service user groups and workstation groups associated with the distributed application objects • The Desktop Application Distribution Wizard configures your Distribution 4 4 Determining the destination’s tree structure, and/or whether to maintain the associations between user/workstation groups or containers and the applications, and/or whether to have automated load balancing or fault tolerance Selects your applications and determines your file copying paths
NAL and TED—Why Do They Need Each Other? • Once you have created the Desktop Application Distribution and it has been built on the Distributor, sent through a Channel, and extracted on the Subscriber, objects in your user groups, workstation groups, and containers at the destination location can use the distributed applications through Zf. D • If the target destination does not have the groups or containers to be replicated, the wizard will help the distribution create them
NAL and TED: Application Distribution Agent • Totally rewritten code for the TED/NAL agent new • No Site Distribution Objects (SDO) • • In Zf. S 2, This object was responsible for holding configuration data that was used in constructing and updating any applications that were created during the TED distribution process Each SDO had a “location list” of which sites would receive the distributed application, that you manually had to update
NAL and TED: Application Distribution Agent • The Application Distribution Agent can • • • Distribute an application to any site by associating the target Subscriber to the distribution Auto associate the target application object to OUs and groups, if the distribution has been defined to do so Create OUs and groups in the target site based on the distribution • Application Linked Site lists support* • Allows users who travel from site to have similar local access to their applications * New feature to Zf. D Prometheus
NAL and TED: Application Distribution Agent O=Digital. Airlines OU=Services OU=NAL CN=Abi. Word CN=Nal_App_Users OU=Airports OU=AM OU=ATL OU=SLC OU=Services OU=NAL CN=Nal_App_Users • Application Abi. Word is created • Group Nal_App_Users is associated with the distributed app
NAL and TED: Application Distribution Agent How did it do that? You can configure your associations during the desktop application distribution wizard setup Maintain Associations • Maintains the associations established in the source tree between the distributed applications and the trusted user/workstation groups and containers • This is done by replicating the associated groups or containers at the target location if they do not exist
NAL and TED: Application Distribution Agent O=Digital. Airlines OU=Services OU=NAL CN=Abi. Word CN=Nal_App_Users OU=Airports OU=AM OU=ATL OU=SLC OU=Services OU=NAL CN=Nal_App_Users • Organizational Unit NAL is created • Application Abi. Word is created • Group Nal_App_Users is created and associated with the app
NAL and TED: Application Distribution Agent How did it do that? You can configure the target directory structure during the desktop application distribution wizard setup Maintain Source Tree Structure • Duplicates the source tree’s structure at the destination’s location for placing the Zf. D application objects
NAL and TED: Linked Site Lists Feature Using the Linking Site Lists feature allows users who travel from site to have similar local access to their applications Example 1. You create the App 1 application object at Site. A 2. You replicate App 1 to Site. B and Site. C 3. You click Link Up Site Lists on the Distributions tab in the App 1 application object’s properties 4. Users who had access to App 1 at Site. A will also have the same local access to App 1 when they travel to Site. B or Site. C Therefore, no matter which site the user is visiting, the application will be available in the same way that they are used to
Making It Happen (Step-by-Step) • The part we won’t show 1. Install Zf. D Prometheus 2. Create new applications, or use previous Zf. Dx applications 3. Install Zf. S 3 Policy and Distribution Services to create distributor— subscriber hierarchies • The part we’ll show 1. Creating TED Channels 2. Creating TED distributions a. Desktop Application distributions 3. Configure distribution hierarchies 4. Configure Site Link Lists
Summary • The combination of Novell Application Launcher (NAL) and Tiered Electronic Distribution (TED) allows you to minimize costs by reducing redundancies, effectively leveraging your existing resources and precisely tracking their use in the enterprise
