3. Backend Implementation (Matt and Brendan)Milestone Project Component 12345 Setup a VMWare ESX serverIC- -- Setup SVNIC- -- Prep a server to run vmweb backend and host the Web InterfaceIC- -- Build stubs, create packages from VMWare provided API and import these into our development environment IC- -- Establish a session with the ESX box over HTTPS using SOAPIC- -- Create objects that will mimic the important entities in vmware (such as virtual machine, host, task) these will be represented as Object Classes in java. IC- -- Develop functions that will query the object structures on the ESX server and return the properties we are looking for. IPP C - Take the returned "Inventory" and instantiate the mimicked objects with the data. These objects will be used to enter data into the MySQL database. IIP C - Develop functions that will abstract the tedious SQL statements out of the functional codeIIP C - Create a task tracking module to update progress on requested jobs from the front-endIIPPE Make a scheduler that will take jobs destined for the ESX server and serialize them as to not do out of order execution of requested actions. IIPC - Time permitting; add ability to create new virtual machines.IIIII Decide upon utility functions which are most relevant and achievable during the scope if this projectIPPC - Implement utilities relevant to the Host machineIPPC - Implement utilities relevant to the Resource PoolIPPC - Implement utilities relevant to the Virtual MachinesIPPC -

4. Front-end Implementation (Ryan)Milestone Project Component 12345 Initialize Project Skelton IP- -- Install Perl IC- -- Install Catalyst Web-Application Framework IC- -- Initialize Application Directory IPC -- Install Perl Module Dependencies IC- -- Include JavaScript framework IIPC - Implement Authentication Module IC- -- Design Authentication DB Schema IC- -- Create Authentication DB IC- -- Create Model for Authentication DB IC- -- Implement UI for login IPC -- Enable model in authentication controller IP C -- Implement Inventory Module IPC -- Create Model for Inventory DB IPC -- Implement UI for Inventory IPC -- Implement Task Module IIPC - Implement CRUD functions for Tasks IIIIE Implement UI for Adding Tasks IPPC -

5. Communication with VMware® API. Database communication. General process logic. Java Stores and retrieves jobs and inventory. Used by back- end Java and front-end perl. SQL MVC to deliver service to the browser and to the user. Style sheets and JS for aesthetics. Perl, HTML, CSS, Javascript

10.  Perform various actions on what are called Managed Objects or Managed Entities.  Managed object/entities exist on the server side and are referred to by the client via Managed Object References (MOR).  For our purposes the MOR's will refer to either a virtual machine, a host machine, a resource pool, or a task.

14.  ORM – Object-Relational Mapping  Creates objects associated with tables in a relational database  Database Model  Creates result class file for each table  Corresponds to row-level data in table  Enable this model in the appropriate controllers  Allows the flow control to query data as necessary  Layer of abstraction – remove DB dependence

15. $c->stash(vms => [$c- >model('InventoryDB::VirtualMachine')->all]); my $host = $c->req->arguments->[0]; $c->stash(host => [$c->model('InventoryDB::Host')- >search({ host_pk => $host })]); $c->stash(template => 'HostView.tt');

16.  Suppose VMWeb::Controller::Inventory  With function sub showHost :Local  /inventory/showHost/x/y/z  /inventory/showHost  Calls the relevant function  x,y,z are arguments stored in context ($c)

23. Implement job contract inside worker thread. Have scheduler's worker threads talk to utility functions Front-end perl code pulling result sets from inventory Front-end perl code placing jobs into job db Front-end perl code monitoring job status End-to-End testing (entire stack functionality)

24.  I must provide data in the database so Ryan can test his result sets  Brendan must provide a job definition contract so I can parse the job from the database and have the worker thread call his functions properly.  Brendan must also send task objects back so the worker threads can monitor completion status and progress.  I must provide Ryan with a table that has currently running and recently executed jobs. I must also clear this table so the interface doesn’t have to. (A read-only set of tables dramatically reduces the chances of SQL injection)

25.  Database concurrency. We are still working on a way to remove entities that no longer exist on the ESX server without truncating the whole table and refilling it.  Foreign Key dependencies MUST BE SPOT ON and update correctly.

26.  Why are we making this so complicated?  While we are writing this for only one ESX host, this framework will take about 1 to 2 weeks of coding to manage a datacenter of hosts and a large amount of VMs on the order of 500-1000 depending on hardware.  Who would use this?  Cloud providers, universities, and large datacenters  Role based access is a highly desired feature.
