Leading the pervasive adoption of grid computing for research and industry • GGF 14 – OGSA MWS BOF • WS-Management • • John Tollefsrud Sun Microsystems © 2005 Global Grid Forum The information contained herein is subject to change without notice

Agenda • • Motivation WS-Management introduction Wiseman open source project Announced supplier support

Trends in systems management • Distributed environments more common. – Crossing companies, geographies, platforms. • Building a common substrate for IT with Web services. – Web services used for: • • • Device discovery and eventing. Single sign on and identity management. Enterprise application integration. Mobile. … • Lifecycle support costs growing, eating up more IT budget. – Over $15 Billion in 2004? – 80% of IT budgets go to running the business, not innovation* Source: “IT Spending, How Do You Stack Up? ”, Gartner, Jan. 2004

Challenges in systems management • Consistent management of systems resources • Consistent reporting of system failures • OS awareness of the hardware state • Monitoring DMZ servers and applications • Net result – high TCO

Addressing the problem Create standard scaleable management protocol Distributed service Systems on one computer CPU, NIC… Scale Up & Down in Software/Firmware • Data model neutral • Composable protocol stack Scale Up & Down on Hardware Devices Clients Servers CORE REQUIREMENTS • Build to support all sizes of device and application • Work in all pre- and post-boot operational environments • Provide consistent access across multiple management models • Enable management across multiple administrative domains • Support access to traditional- & SOA-based applications equally • Make it secure, on all devices • Tightly align with WS-* arch. • Aim for future-proof

What is WS-Management? • WS-Management defines a SOAP-based protocol for Systems Management WS-Management • Is a profile – a collection of references to First Published: other composable specs – WS-Addressing, WS-Eventing, WS-Transfer and WSEnumeration • Specifies extensions to and restricts how these protocols can be used • Designed to scale down to small-devices • Defined over existing standards – HTTP/S, TCP/IP, TLS, XML, URI, SOAP • Designed to be Model-agnostic – compatible with the CIM Object Model Oct 2004 Authors: AMD BMC Dell Intel Microsoft Sun WBEM Solutions

WS-Management targets typical management operations • Typical systems management operations – Get, Put and Delete properties of managed resources – Create references to manageable resources – Enumerate the contents of containers and collections such as large tables and logs – Subscribe to events emitted by managed resources – Execute specific management methods – (Resource Discovery is out of scope in the current version of the spec) • Operations are optional in WS-Management and implementations are free to add more

WS-Management Transfer functions • Defined by WS-Transfer – – Get Put Create Delete • Defined by WS-Mgmt – Partial Get – Partial Put – Rename

Enumerating data sources • Same as WS-Enumeration specification • WS-Management allows using partial results Enumerate ponse Enumerate. Res (Context) Pull(3) Pull. Response Pull(4) Pull. Response Release. Respo Client Agent Item Collection

WS-Management Eventing functions • Defined by WS-Eventing • Defined by WS-Management – Subscribe – Push. With. Ack – Batched – Pull Deliver Management Console Get Subscribe Group Policy Server

Heartbeats • Pseudo-events as part of subscription monitoring • Instruction included in wse: Subscribe

Bookmarks • Optional capability for Log-backed subscriptions • Bookmark is included with each event delivery – Service-defined cursor in the event stream – Opaque to the client • Allows a later restart where the subscription left off

Security Profiles • Request-reply – wsman: secprofile/https/standard – wsman: secprofile/https/mutual • Events – wsman: secprofile/https/standard/user. Ref – wsman: secprofile/https/mutual/certhash • Not an exhaustive list, more profiles could be supported

WS-Management Catalog • Lists the available Resource. URIs • Provides searchable metadata (Keywords) • Provides relationships to external and internal resources (eg Web URLs) • Describes supported actions for each resource • Can provide the complete WSDL for a resource using WS-Transfer: Get • Can provide the XML Schema for a resource using WS-Transfer: Get

Implementation • The wiseman project

The wiseman project • https: //wiseman. dev. java. net • An open source project by Sun Microsystems • Apache License 2. 0 • Prototype code – not yet product-quality – Developed outside of formal processes – Architecture, APIs can change • Proven interoperability • Initial Implementation is for Java SE 5+

Wiseman project base technologies • Java SE 5+ – Base platform • org. w 3 c. dom – Document, Element, Node, Attributes • SOAP with Attachments API for Java (SAAJ) 1. 3 – Message, Envelope, Body, Header, Fault • Java Architecture for XML Binding (JAXB) 2. 0 – XML ↔ Java (based on Schema)

Wiseman handler architecture

Wiseman project to-do’s • WS-Management – Fragment-level WS-Transfer – Eventing extensions – Many Faults • CIM Mapping • WS-Managment Catalog • A Simple API for the casual developer • Documentation – Java. Doc, FAQ, Developer Guide

Delivering WS-Management Suppliers have announced WS-Management product plans

Sun Microsystems product support for WS-Management • Sun announced product support plans: – x 64 servers / service processors in 2006 – Solaris – N 1 Preso source: Microsoft Win. HEC 2005

Microsoft Windows Server 2003 “R 2” (2005) • Supported features – WS-management stack (server and client) – Supports HTTPS – in-band OOB – IPMI kernel driver (supports version 1. 5 or higher) – IPMI provider – subset of CIM IPMI profile – Support for X 86, IA 64, AMD 32/64 – Report SEL events to NT event log – Report BSOD and shutdown to BMC SEL – Remote subscriptions to SEL events OOB (over HTTPS) – Scripting client API (OLE Automation) • Limitations – Only subset of classes in IPMI CIM profile supported – Only supports management controllers with KCS interface – Only supports https – No remote discovery of WMI instrumentation Preso source: Microsoft Win. HEC 2005

WS-Management & Microsoft Operations Manager • Windows Server 2003 “R 2” – Existing MOM agent can integrate using WS-man scripting interface – Management Packs can be modified to support IPMI • Windows Longhorn and MOM V 3 – Use of WS-Management for agentless monitoring across firewall – Use of WS-Management for OOB access – Down-level support is planned (Windows Server 2003 SP 1 or newer releases) • Support out-of-band access for existing BMC – Not included in Windows – Delivery vehicle TBD Preso source: Microsoft Win. HEC 2005

Windows Longhorn Update (planning in process) • Forwarding OS events – Client side monitoring – Forwarding from DMZ servers • TCP transport – SOAP framing protocol – Integrated security for Windows to Windows scenarios • New administration tools in the box – Instrumentation viewer – New Event Viewer • Additional h/w management capabilities – Set of additional IPMI profiles for richer h/w management experience • Full access to and discovery of WMI instrumentation – CIM to XML mapping – Mapping WMI namespaces to Catalog Preso source: Microsoft Win. HEC 2005
