SmartFrog
Smart Framework for Object Groups (or SmartFrog) is a
powerful and flexible Java-based software
framework for configuring, deploying and managing distributed software
systems.
With SmartFrog, system configuration details such as: which
components
make up the system, on which computers those components should run, how
the individual components are configured, in what order they are
started, and how they are combined into a complete system, are captured
in "system descriptions".
SmartFrog consists of the SmartFrog Language, the runtime,
which
interprets the language, and the Component Descriptions that the
runtime configures and deploys according to the templates provided in
the language.
The configuration of components is described using
a domain-specific language, whose syntax resembles that of Java. It is
a prototype-based object-oriented language, and may therefore be
compared to Self, an object-oriented programming language.
Features include:
- Systems can be installed, started, stopped and uninstalled
completely automatically
- Increased flexibility: you can radically change the
deployment architecture by altering the configuration files. This lets
you experiment with different configurations for enhanced performance
or reliability
- Rapidly bring up new hosts, real or virtual, and install
applications in them. This makes it easier and cheaper to scale out an
application
- Reduced configuration errors. The language
elimates duplicate information, sharing it between components instead
of relying on cut-and-paste duplication. Furthermore, if the SmartFrog
configuration files are kept under revision control, it is easy to roll
back to previous configurations
- Enables a rapid, integrated build-deploy-test cycle. As you
can now deploy from your build, running tests against deployed systems,
developers can integrate deployment and functional testing of their
deployed systems into their build cycle. And not just the developers
-the Continuous Integration server can deploy and test systems too.
rticularly when the complexity of the overall system starts to grow
