Dear Wiki user, You have subscribed to a wiki page or wiki category on "Tomcat Wiki" for change notification.
The "TomcatGridDiscussion" page has been changed by theimpaler: https://wiki.apache.org/tomcat/TomcatGridDiscussion?action=diff&rev1=12&rev2=13 Considering all the above, the following phases could be considered as a base line for the road map of the Tomcat Grid. ''markt: I'd like to see a little more high level architecture to steer development. For example, is there a common core of management functionality that we then wrap with a web-based GUI and a CLI? That would allow others to write other wrappers to plug this into other tools.'' + + ''vlad: I would like to provide as much detail as you need, but I'm afraid I still I don't quite understand exactly what you do you refer as the architecture. Anyway, below is a general overview of the software modules and their responsibilities.'' + + {{TomcatGridSoftwareModules.png}} + + ''The modules are: + + * '''Core module''': Shared logic to be used by all other modules. + * Core data types, such as "Machine", "Instance". + * Share core logic. For example, grid configuration file parsing/update. + * Defines the Grid Agent functions (as interfaces), but does not implement them. These are used by all Managers modules. + * Common utility classes. + * Common exceptions. + + * '''Web Manager module''': A JEE Web application that includes: + * Includes a simple Managing web GUI: web pages, navigation logic. + * Uses the Core module for functions such as: + * Load Grid Configuration, + * Interact with grid agents. + + * '''CLI Manager module''': A java command-line program: + * Command-line interface: command parsing, text output. + * Uses the Core module for functions such as: + * Load Grid Configuration, + * Interact with grid agents. + + * '''Any other Manager module''': Any future module that needs to connect to Grid Agents to manage Tomcat instances. + + * '''Grid Agent module''': Responds to Managers calls and controls local Tomcat instances. + * Listen to Manager requests. + * Implements the Grid Agent interfaces. + * Includes the high-level interaction with Tomcat intances. + * Defines and uses the Tomcat Management Primitives (as interfaces), but does not implement them. + * Receives content (deployables, grid configuration changes) and applies them. + + * '''Grid Agent Primitives for Linux''': + * Implements the Tomcat Management Primitives for Linux OS. + + * '''Grid Agent Primitives for Windows''': + * Implements the Tomcat Management Primitives for Windows OS. + + * '''Grid Agent Primitives for Mac''': + * Implements the Tomcat Management Primitives for Mac OS. + + * '''Grid Agent Primitives for Other''': + * Implements the Tomcat Management Primitives for Other OS. + + + The executables themselves are comprised of several modules each that are assembled during the build. + * The Grid Web Manager Executable (a WAR) includes: + * Core module + * Web Manager module + * The Grid CLI Manager Executable (a JAR) includes: + * Core module + * CLI Manager module + * The Grid Agent Executable (a JAR) includes: + * Core module + * Grid Agent module + * Grid Agent Primitives for Linux + * Grid Agent Primitives for Windows + * Grid Agent Primitives for Mac + * Grid Agent Primitives for Other + '' == Phase 1 - Core Grid Operation == The first phase includes the most basic features, in order to provide a functioning and useful first version of the Grid. --------------------------------------------------------------------- To unsubscribe, e-mail: dev-unsubscr...@tomcat.apache.org For additional commands, e-mail: dev-h...@tomcat.apache.org
