Problem 1
4
Infrastructure a 2nd class citizen

• Infrastructure isnt viewed with the same rigour
  as solution architecture
• Infrastructure isnt considered when the solution
  is being designed
• Solution competitive advantage
• Infrastructure cost centre

5
Problem 2

• Black box applications are difficult to support
• They require support staff to have specialist
  application knowledge

6
Solutions not designed for operations

• Applications are built to solve Functional
  Requirements
• Exposing the information IT Professionals need to
  support the application is low priority
• What information do IT Professionals need?

7
Problem 3

• How do you fix these problems?
• My application is slow
• My application keeps failing
• My application doesnt scale
• How do I provide Disaster Recovery?

Root Causes

• Solutions and Infrastructure designs are not done
  in parallel
• Solutions arent designed to be supported (or
  deployed, maintained)
• Solutions are mystical boxes

11
The Ideal World If only

• If you modelled the
• Data centre
• Application
• You could
• Test the security
• Test the compatibility of the app with the
  infrastructure
• Get some idea on the scalability
• Get some idea on the performance
• The impact of change would be known, understood
  and not feared

12
Demo

• Models let you perform what if against your
  applications

• Developer constraints

15
Models

• IT Professional
• System topology
• IT governance model
• Servicing model

16
Models

• End User
• Service level agreements
• Business requirement model

17
System Definition Model (SDM)

• System Definition Model (SDM)
• A formal model of a complete system
• All information pertinent to deployment and
  operations
• Machine-readable, capturing intent of developers
  and administrators
• System topology
• Developer constraints
• IT policy
• Installation directives
• Health model
• Monitoring rules
• Service Level Agreements
• Reports

What is a Health Model?

• A health model documents how to detect and verify
  the operational state of an application and how
  to resolve any problems
• Health Models Tell IT Operations
• What's not working
• How bad is it
• What should be done to return application to
  normal
• How to determine whether an application is
  healthy again

20
What is in a Health Model

• Managed Entities Aspects
• What is being managed
• Detectors
• How to detect state
• Diagnostics
• How to identify root-cause
• Verifiers
• How to verify the problem exists
• Resolvers
• How to correct the problem

21
Managed Entities

• Managed Entity
• Application, Component, Service or Dependency
• Example
• Transport Order Application
• Transport Web Service
• Warehouse Management Application
• Arranged into a Logical Hierarchy

22
Aspects

• Part of Managed Entity that an administrator
  would want to monitor
• Can only be in one health state at a time (green,
  yellow, red)
• Example
• Configuration
• Database
• Security
• General Functionality

23
Aspects
24
Aspect State

• State of an Aspect
• Green Aspect Functioning Normally
• Yellow Aspect is partially functioning but at
  some degraded level
• Red No Service is being provided by this Aspect
• Detectors
• Indicate the State of an Aspect
• Performance Counters
• Windows Events
• Absence of Event
• Example
• Event ID 24 Server Not Found

Event ID 24 occurs
25
Determining Managed Entity State

• What impact does an Aspects Health State have on
  its Managed Entity?
• What impact does a Managed Entity have on its
  Parent?
• Example
• Because the connectivity of the Web Service is
  Red, the impact on the Transport order
  Application is also Red. However, the impact on
  the Shipping Service is only yellow because the
  Warehouse Management Application is green

26
Determining Managed Entity State
27
Demo

• Application before creating a Health Model

28
Diagnostic Information

• Narrow high-level problems to likely root-causes
• Manual Investigation
• Events
• Event can generally indicate cause
• Very specific in guiding towards root cause
• WMI
• Expose Internal State Configuration
• Performance Counters
• Example
• Check Event log for network related errors
• Check IP configuration
• Check Remote Server is Running

29
Verifiers

• How to verify the problem still exists
• Server Not Found
• Check you cannot communicate with the server
  usingping ltservernamegt

30
Resolvers

• Document how to correct the problem
• What Steps are Required
• Sometimes, its still get hold of Fred

31
Who Builds a Health Model?

• Who "Builds" a Health Model
• Architects
• Developers
• IT Administrators/operations staff
• Who modifies the Health Model
• IT Administrators
• Architects
• Developers
• Who Contributes to the Health Model
• IT Administrators
• Developers
• Architects
• QA
• Information Workers

32
Why Build a Health Model?

• Architecture - Guides adding the RIGHT
  instrumentation and ONLY the instrumentation your
  customers need
• Allows IT Operations to help themselves which
  means developers have to support applications
  less often
• Meet Customer Demands for Lower TCO

33
Demo

• Application after implementing a Health Model

34
How to Build a Health Model

• Identify Managed Entities
• Arrange into Logical Hierarchy
• Identify the Aspects
• Define Detection Instrumentation (Detectors)
• Capture Verification Knowledge
• Capture Diagnostics Knowledge
• Capture Resolution Knowledge
• Create Rollup Monitors for like-category aspects
• Implement Instrumentation

35
Building a MOM Management Pack

• Generate starting Management Pack from your
  health model
• Structure
• Monitors
• Rules
• Knowledge
• Edit in MOM Authoring Console
• Managed Entity Discovery Logic
• Views and Reports
• State Monitoring Rules/Views

36
Health Model Deliverables

• Copy of Health Model
• Instrumented Application
• IT Staff can use Windows Tools to Manage
  Immediately
• Optionally Management Pack for MOM

37
Health Model Tools

• Management Model Designer Beta
• Build a Health Model
• Generate Partial Management Pack
• Hierarchy
• Rules
• Knowledge

38
Health Modeling Best Practices

• Ensure Operations and Business people drive the
  Health Model
• Capture your Health Model electronically in a
  schematized file
• Break application into Hierarchy of Managed
  Entities
• Capture Verification, Diagnostic, Resolution
  knowledge in the model
• Use Health Model to drive the RIGHT
  instrumentation in your application
• Use Health Model to generate a MOM management
  pack if required

39
Non-functional Requirements

• Health Models help
• Meet SLAs
• Applications Scale
• Reduce the cost of Operations
