Present day IT environments are complex, heterogeneous in terms of software & hardware from multiple vendors.
Computing systems have evolved into millions of interconnected devices whose interactions create complex web on increasingly complex architecture.

It is a term coined by IBM .
Principle similar to autonomic nervous system.
Its main aim is to make computer system more self managing and elastic, removing obstacles to growth and flexiblity.
Helps to address complexity by using technology to manage technology

“Civilization advances by extending the number of important operations which we can perform without thinking about them”- ALFRED NORTH WHITEHEAD
This quote made by the preeminent mathematician Alfred Whitehead holds both the lock and the key to the next era of computing.
The high-tech industry has spent decades creating computer systems with ever- mounting degrees of complexity to solve a wide variety of business problems.
WHY AUTONOMIC COMPUTING
![Page 9: Autonomic Computing](https://reader033.fdocuments.in/reader033/viewer/2022052310/54724f6fb4af9f285b8b4569/html5/thumbnails/9.jpg)
Ironically, complexity itself has become part of the problem. It’s a problem that's not going away, but will grow exponentially, just as our dependence on technology has
To overcome this problem IBM suggested a solution: build computer systems that regulate themselves much in the same way as our autonomous nervous systems regulates and protects our bodies.
This new model of computing is called autonomic computing

Monitor and tune resources
automatically– Support operating inunpredictable
environment– Efficiently maximization
ofresource utilization
withouthuman intervention
Dynamic resource allocationand workload management.
– Resource: Storage, databases,networks
– For example, Dynamic server clustering

LEVELS OF AUTONOMIC MATURITY

BASIC :
IT professionals manage everything by hand.
MANAGED :
Data are collected from the system (via sensors) and selected . The time is reduced.
PREDICTIVE :
Recognition of patterns and suggestion of a solution, the decision is made still by human.

ADAPTIVE :
The system makes and applies the solutions.
IT staff provides policies used for plans and monitors system’s actions.
AUTONOMIC :
Integrated IT components are collectively and dynamically managed by business rules and policies.

ARCHITECTURE
Autonomic element is the fundamental atom of the architecture
It consist of two parts Managed Element Autonomic Manager
Consist of one or more managed elements coupled with a single autonomic manager
![Page 22: Autonomic Computing](https://reader033.fdocuments.in/reader033/viewer/2022052310/54724f6fb4af9f285b8b4569/html5/thumbnails/22.jpg)
A Managed Element can be:
Hardware resource, CPU, database, Application service, etc.
The components and functions of a single autonomic manager often referred to as the "MAPE loop" for Monitor, Analyze, Plan, and Execute, supplemented by a Knowledge base.

Core building blocks for an open architecture
Management using MAPE:– Monitoring managed elements and their external environment– Analyzing the gathered information– Planning and executing based on information

MONITOR
An autonomic manager monitors instrumentation data from multiple sensors in a system.
The sensors "sense" various aspects of the state of the monitored computing system.
This can include aspects of the hardware instrumentation, ambient information ,and aspects of the software components

ANALYZE
This component of the autonomic manager contains the intelligence required to interpret and correlate the above mentioned instrumentation data.
This component usually has the ability to consult historical data and to compare them with current state to detect significant changes.

PLAN Once an analysis report of the situation is completed, the
planning component can define a series of control actions that should bring the system to a normal operating range.
EXECUTE This component receives the series of action steps from the
planning component, and puts the plan into action.
It activates appropriate control points, or effectors, on the managed platform following the proper sequence and timing

KNOWLEDGE BASE
This serves as a repository of knowledge, such as historical data and policies, which can be utilized by the other components in their operation.
