Today's computing environments are
becoming increasingly sophisticated. They involve numerous complex
software that cooperate in potentially large scale distributed
environments. These software are developed with very heterogeneous
programming models and their configuration facilities are generally
proprietary. Therefore, the administration of these software
(installation, configuration, tuning, repair …) is a much complex task
which consumes a lot of resources:
· human resources as administrators have to
react to events (such as failures) and have to reconfigure (repair)
· hardware resources which are often reserved
(and overbooked) to anticipate load peaks or failures.
A very promising approach to the above issue is to implement
administration as an autonomic software. Such a software can be used to
deploy and configure applications in a distributed environment. It can
also monitor the environment and react to events such as failures or
overloads and reconfigure applications accordingly and autonomously.
The main advantages of this approach are:
· Providing a high-level support for deploying and
configuring applications reduces errors and administrator's efforts.
· Autonomic administration allows the required
reconfigurations to be performed without human intervention, thus
saving administrator's time.
· Autonomic administration is a means to save
hardware resources as resources can be allocated only when required
(dynamically upon failure or load peak) instead of pre-allocated.
The goal of this project is to design and prototype an environment for
developing autonomic administration software. Our works in this domain
allowed us to identify the following key design choices:
· A component model. The administrated environment
should be modelized as a component-based software architecture which
provides means to configure and reconfigure the environment. The same
model should be used for developing the administration software itself,
thus enabling self-administration.
· A system representation which provides a
consistent and reliable view (snapshot) of the whole administrated
· Control loops which link probes to reconfiguration
services and implement autonomic behaviors.
A first prototype has been developed and is operational. It has been
used for the administration of clustered J2EE applications. These
applications rely on very complex software (e.g. Apache, Tomcat, Jonas,
Mysql) and their deployment and administration was greatly facilitated
by the use of the prototype.
We are also investigating the use of this prototype for the
administration of scientific (computation intensive) application on a
large scale-grid infrastructure (the french national Grid'5000
Many contributions are expected in this project, as extensions to the
current prototype, developments of new autonomic administration
policies, studies with different administrated environments.
