vSphere Web Client (VWC) Architecture Overview

VWC main characteristics for plugin developers

Open platform with a true web architecture

Extensibility at its core

• UI extensibility

• Data extensibility

Easy to build a unified user experience

• Consistent look & feel

• Data mash-ups

Rich SDK and developer tools

Extensibility Framework

Design Goals

Promote extensibility by design rather than implementation

Enable UI customization, consistency and easy navigation

Keep optimal footprint

• Lazy loading of metadata, resources & code modules

9

Extensibility Framework

Key Concepts

Extension Point

• Declaration of an extensible feature

Extension

• Implements an extension point

Plugin

• Bundle of metadata, code

and resources

Plugin package

UI plugin bundle1 (.war)

UI plugin bundle2 (.war)

Java service bundle3 (.jar)

Data adapter bundle4 (.jar)

3rd party library X (.jar)

plugin-package manifest (.xml)

my-packaged-solution (.zip)

Packaging & Deployment

Example of a plugin-package manifest

<pluginPackage id="com.vmware.samples.viewspropertiesui"

version="1.0.0"

name="Views Sample”

vendor="VMware" >

<dependencies>

<pluginPackage id="com.vmware.vsphere.client" version="5.5.0" />

</dependencies>

<bundlesOrder>

<bundle id="com.vmware.wsvim25" />

<bundle id="com.google.gson" />

<bundle id="com.vmware.samples.custompropertyprovider" />

<bundle id="com.vmware.samples.custompropertyui" />

<bundle id="com.vmware.samples.viewspropertiesui" />

<bundle id="com.vmware.samples.wssdkprovider" />

<bundle id="com.vmware.samples.wssdkui" />

</bundlesOrder>

</pluginPackage>

11

Packaging & Deployment

How do you deliver your new plugin to users?

1. Create a plugin-package .zip

2. Provide a script to register the plugin as a vCenter extension,

with a URL pointing to the plugin-package .zip location.

3. When a new user session starts, VWC finds your plugin and hot-

deploys it to the app server if necessary.

What about new versions?

Only the latest version of the plugin is deployed.

When a newer plugin version is registered the older one is

un-deployed automatically.

12

Extension Templates

A collection of pre-defined extension points and extensions

Out-of-the-box templates

• Instantiating an object workspace for new object types

• Instantiating a summary view

<!-- Chassis object view template instance.

Defines the object workspace (right hand side) for the Chassis object. -->

<templateInstance id="com.vmware.samples.chassis.viewTemplateInstance">

<templateId>vsphere.core.inventory.objectViewTemplate</templateId>

<variable name="namespace" value="com.vmware.samples.chassis"/>

<variable name="objectType" value="Chassis"/>

</templateInstance>

13

Extension Templates – Custom object workspace

14

Extension Filtering

Allows filtering based on runtime conditions

3 filters

• Object type

• Typically used for actions

• e.g. Show the extension only if the selected object is a VirtualMachine

• Object properties

• e.g. Show the extension only if the VM is FT enabled

• Privileges

• e.g. Show the extension only if the user has a specific privilege

15

Extension Filtering – Type Filter

<extension id="vsphere.core.vm.faultToleranceTurnOnActionSet">

<extendedPoint>vise.actions.sets</extendedPoint>

<object>

…

</object>

<metadata>

<objectType>VirtualMachine</objectType>

</metadata>

</extension>

Example of an action appearing only for VirtualMachine objects:

16

Extension Filtering – Privilege Filter

<extension id="vsphere.core.vm.ftView">

<extendedPoint>vsphere.core.vm.summarySectionViews</extendedPoint>

<object>

…

</object>

<metadata>

<privilege>VirtualMachine.Interact.CreateSecondary</privilege>

</metadata>

</extension>

Example of a portlet extension for users who have a specific privilege:

17

Extension Filtering – Object Property Filter

<extension id="vsphere.core.vm.ftView">

<extendedPoint>vsphere.core.vm.summarySectionViews</extendedPoint>

<object>…</object>

<metadata>

<privilege>VirtualMachine.Interact.CreateSecondary</privilege>

<propertyConditions>

<com.vmware.vsphere.client.filters.PropertyConditionsInfo>

<conditions>

<com.vmware.vsphere.client.filters.ComparisonInfo>

<propertyName>runtime.faultToleranceState</propertyName>

<comparisonOperator>EQUALS</comparisonOperator>

<propertyValue>enabled</propertyValue>

</com.vmware.vsphere.client.filters.ComparisonInfo>

</conditions>

<conjoiner>AND</conjoiner>

</com.vmware.vsphere.client.filters.PropertyConditionsInfo>

</propertyConditions>

</metadata>

</extension>

Portlet extension restricted to VMs with a specific property enabled:

Demo

A real life plugin, which displays special VM guestOS information

which is not normally visible in the vSphere Client

20

My Challenges

vSphere Web Client extensions works in a different manner compared

to .NET client

vSphere Web Service SDK is used in a different way

• No need for WaitOptions, RetrieveServiceContent and login

(.NET lovers) .NET UI extensions are not possible, but a plugin can call

an external .NET web service

21

What I Learned from My Mistake

Start simple – don’t try to start creating complex and fantastic code,

start simple, your self-esteem will thank you

Don’t reinvent the wheel – everything needed to manage a vSphere

infrastructure is here, no need to develop strange server component

Read the documentation – example codes are very important but

sometime reading the doc is a must!

Compatibility Story

Ground rules:

• vSphere Web Client works with the previous vCenter release

• Plugins are supported for at least one more VWC release

Compatibility w/ vCenter 5.0 vCenter 5.1 vCenter 5.5

VWC 5.1 OK OK No

VWC 5.5 No OK OK

Compatibility w/ VWC 5.1 VWC 5.5

Plugin + SDK 5.1 OK OK

Plugin + SDK 5.5 No (1) OK

(1) Cannot use 5.5 features in a plugin targeting VWC 5.1, otherwise it is OK.

24

SDK 5.5 Changes

New features

• Solution menus

• A better way to build solution-specific menus

• Action prioritization

• 2 new extension points to order or promote actions

• Finally possible to put a global action in the list toolbar

• AdvancedMouseEvent

• Listen to right-click events in your own widgets

• DisposeManager improvements and new extension point

• You can decide under which namespace your Flex objects will be GC’d

• Dialogs and Wizards

• Wizard data can be saved during the user session or across sessions

• But support limited to 5.5 for now because of upcoming platform changes

25

SDK 5.5 Changes (cont’d)

Other important changes

• Better samples

• Virgo updated to 3.6

• Spring Framework libraries updated

• Java version 1.7 (compile with target 1.6)

• Flash Player version >= 11.5

• Web-ContextPath must use this format: vsphere-client/plugin-name

• See [SDK]/docs/release-notes.html for all details

Your plugin package must now include a 5.5.0 dependency

<pluginPackage id="com.acme.acme-plugin" version="1.0.0”

name=”Acme solution” vendor=”ACME">

<dependencies>

<pluginPackage id="com.vmware.vsphere.client" version="5.5.0" />

</dependencies>

SDK Roadmap

We’re moving away from Flex as UI technology

Our future HTML 5 platform will preserve your investments

The Java tier doesn’t change

You will be able to take several paths during this transition

• Keep using Flex UIs in the short term

• Mix Flex UIs with HTML

• Use only HTML/Javascript

• Stick with C# client Script plugins

28

SDK Roadmap (cont’d)

Flex UI plugins

• For the short term this is still the best way to integrate your UI with VWC

• The entire vSphere UI suite is using this!

• Will be supported by HTML 5 platform

• Except deprecated APIs

• Columns extensions and portlets have limitations

Use cases

• Continuing existing investment

• Starting a simple plugin

• Building a UI plugin for vSphere 5.1 and 5.5

Tips

• Reducing your UI code will make the transition easier

• For complex UIs consider mixing some HTML views

29

SDK Roadmap (cont’d)

C# client script plugins

• Can use HTML/Javascript

• Limited integration with the Web Client

• Fewer extension points, views displayed in separate tab Classis Solutions

• Security warning because of HTTPS link to external server

• Missing APIs (no callback into Flex)

• No Java service layer

• Will be supported in HTML 5 platform with some exceptions

Use case

• Re-using or enhancing an existing script plugin

• Writing a new plugin that must also work in the C# client

Tips

• All new development should focus on true Web Client plugin, with a Java

service layer, and a UI either in Flex or HTML

30

SDK Roadmap (cont’d)

New HTML/Javascript plugin support

• Coming with the existing VWC 5.5 platform!

• Full SDK support, all extensions are supported

• Easiest transition to future HTML 5 platform

• Use the HTML widgets and Javascript libraries of your choice

• Add or re-use Java services in the mid-tier

• Possible to mix Flex and HTML

Beta-release coming soon
