Autonomic Computing

An Introduction

Guenter Kickinger

  • Autonomic Computing in General – IBM’s perspective
  • Technologies & Tools
  • Autonomic Computing and the Grid
  • What can AC do for us?
the problem increasing complexity of it systems
The Problem – Increasing Complexity of IT Systems
  • Complex systems require more and more skilled IT professionals to install, configure, operate, tune and maintain.
  • Difficulty of managing today’s computing systems goes well beyond the administration of individual software environments. New levels of complexity:
    • Integration of several heterogeneous environments into corporate-wide computing systems
    • Extension beyond company boundaries into the Internet
    • Architects are less able to anticipate and design interactions among components
    • Systems will become too massive and complex for even most system integrators to install

autonomic computing the solution
Autonomic Computing – The Solution (???)
  • Autonomic computing helps address these complexity issues by using technology to manage technology.
  • Term “autonomic” is derived from human biology – autonomic nervous system.
    • adjusts to many situations automatically without external help.
    • ANS monitors your heartbeat, checks your blood sugar level and keeps your body temperature close to 37, without any conscious effort on your part.
  • The vision: computing systems that can manage themselves given high-level objectives from administrators.
    • Manage complexity
    • “Know” themselves
    • Continuously tune themselves
    • Adapt to unpredictable conditions
    • Prevent and recover from failures
    • Provide a secure environment
components of self management
Components of Self-Management
  • self-configuring
    • components adapt dynamically to changes in the IT system, using policies provided by IT professionals.
    • e.g. deployment of new components, removal of existing components
  • self-healing
    • environments can detect problematic operations and then initiate corrective action
    • system identifies and isolates a failed component. Comp. is taken offline, repaired or replaced.
  • self-optimizing
    • to make the best use of available resources even though these resources and requirements are constantly changing.
  • self-protecting
    • to allow authorized people to access the right data at the right time
    • to detect hostile or intrusive behaviour
    • to take autonomous actions to make the system less vulnerable.

technologies tools 1
Technologies & Tools (1)
  • IBM Emerging Technologies Toolkit (ETTK)
    • software development kit for designing, developing, and executing emerging autonomic, web service, and grid-related technologies.
    • evolved from the Web Services Toolkit (WSTK)
    • includes a fully-functioning SOAP engine and embedded application server
    • provides
      • basic software components to experiment with and create Web services and autonomic programs
      • architectural overview of autonomic technologies, Web services, sample programs, utility services and tools for developing and deploying autonomic programs and Web services.
    • Technologies: WSDL, SOAP, WS-ResourceFramework

Technologies & Tools (2)
  • IBM Autonomic Computing Toolkit 2.0
    • The IBM autonomic computing toolkit is a collection of
      • technologies,
      • tools,
      • examples,
      • scenarios, and
      • documentation

that is designed for users wanting to learn about, adapt, and develop autonomic behaviour in their products and systems.

      • Autonomic Management Engine
      • Generic Log Adapter (to translate product log messages into a Common Base Event data format)
      • Log and Trace Analyzer
      • Integrated Solutions Console

ac and the grid
AC and the Grid
  • Grid as an enabling technology
    • The Grid provides the open protocols needed for AC, like OGSA, WS-RF
  • Autonomic Grid Applications
    • context-aware self-managing applications in widely distributed, heterogeneous Grid environments
    • Extending the Grid middleware by autonomic capabilities

What Can AC Do For Us?

Help to make the interactive data analysis stable, in a heterogeneous Grid environment

making interactive data analysis robust improving proof
Making Interactive Data Analysis Robust – Improving PROOF
  • Applying autonomic computing concepts, but dynamically at runtime rather than for system administration purposes
  • self-configuration
    • dynamic slaves
      • PROOF slaves leave (e.g. resources are not longer available)
      • PROOF slaves join (e.g. new resources become free)
    • if user aborts execution, all processes should be aborted too (Ctrl-C feature)
making interactive data analysis robust improving proof1
Making Interactive Data Analysis Robust – Improving PROOF
  • self-healing
    • analyse why processes are dying
      • e.g. error in selector script (DIV by 0)
    • find the best strategy to recover from the error
      • restart the process on another CPU?
      • what about intermediate results?
  • self-optimization
    • Learn from previous analysis sessions how to improve performance
  • self-protection
    • Analysis of possible threats has to be done
    • Security issues (authentication, encryption,…)
    • Protected environments for selector scripts
  • autonomic computing is a concept of self-managing IT systems, analogous to the autonomic nervous system of the human (animal) body
  • the principles of the autonomic computing can be used to make the interactive data analysis framework more robust (i.e. PROOF)
  • To do so, the IBM focus of AC – the self-management of an IT system infrastructure to reduce IT costs – has to be shifted to the self-management of the distributed interactive data analysis process
