2 levels of interest Deployment µkernel

Bootstrap core for loading extended functionalityClass LoadingDownloading/Installation/Uninstallation

Application deployment Potential extended functionality modules

Packaging, Description, Deployment Life Cycle Activities(configuration, dependencies, …), Monitoring, Fault tolerance,Distributed vs Local (1 site), others ???

Target PlatformsJOnAS JSR88, OpenCCM, OSGi use cases, Fractal

Common deployment toolsAdministration console, etc.

Common deployment modelsReference deployment infrastructure architectureApplication deployment models

What’s next Software deliverable V1: 15th of July

Workshop proposition 27 October in Grenoble

DÉCOR conference (28-29 october) First evaluation on personalities

implementations Software deliverable v2 : 15th of

December

6

GDF(High Level)

Generic Deployment Framework

7

Motivations (High Level) Generic Deployment Framework

Independent from the platform But Heterogeneous applications (OSGi+J2EE+CCM)

Personalities of this FW OSGi, J2EE, CCM, Fractal, ProActive, …

Model-based Application, Site, Process

8

Which issues are not addressed by GDF ? Bootstrapping ? ClassLoading Packaging

Platform specific : RPM, Bundle Jarfile, EAR Jarfile Metadata Formats

Java .MF, RPM multi-files, .NET XML manifest, … Protocols

Between global and local deployer rsh, rlogin, ssh, Globus 1,2 …, PBS, LSF, MapRsh telnet, http, https, soap, xmlrpc, javagroup ?, ip

multicast+carrousel … Should GDF address them ?

The right place (low level GDF)

Model Unit, DeployedUnit Application, DeployedApplication Site, Organization

Dependency / Attributes Resolver Process

15

Model

16

Attributes & Dependency Attributes

Set of properties <key,values> Platform-specific

OSGi: Export-Package, Import-Package, Bundle-Version … …

Application Developpement status: beta …

Dependency Represents a constraint

Eg: the Unit A requires os=Windows Eg: the Site B requires stable Units Eg: the Application C is composed only of signed units by

ObjectWeb Resolved or not by a Attribute

17

Unit represents a deployment unit

have attributes Encapsulated platform specific metadata (Bundle-UpdateLocation,

…) have dependencies

towards unit Eg: the unit requires the package javax.servlet; version=2.3

towards sites Eg: the unit runs only under WindowsXP and more

towards applications Eg: the unit cannot be use in a commercial application

could embed others units Eg J2EE EAR = EJBJAR + n WAR + m JAR (of client side applications) WAR could contain MidLets and Applets

DeployedUnit represents a deployed unit on a site or in an organization

18

Unit DeployedUnit

represents a deployed unit on a site or in an organization

OMG D&C term : package

19

Application represents an application

have attributes have dependencies

towards units UnitDependency enables to fix the units that compose the

application towards sites

Eg: the unit runs only under WindowsXP and more Dependencies are added by

the assembler, the deployer, … DeployedApplication

represents a deployed applicationon a site or in an organization

20

Application Q: Can an application be a set of

(sub)applications

Federation of Applications Heterogeneous applications

One part on OSGi Another on J2EE …

Other examples

21

Site represents a site on which a part (units)

of an application are deployed have attributes have dependencies

towards applications Eg: the application must be stable dev. version

towards units Eg: the units must be licenced Open Source

Organization A set of sites

22

Identity Platform-specific

OSGi: Bundle-UpdateLocation for Unit …

One common method Object getId() Test equality

23

UnitRepository Only an index of available units Not a storage system (platform-

specific) Units could be loaded from a URL or

from a InputStream In the case of URL loaded, the URL

must be one of the attributes of the Unit

24

ApplicationRepository TODO

25

Concrete DependenciesCommon

UnitDependency LdapFilterDependency ConjunctionDependency DisjunctionDependency NotDependency FacetDependency QualifiedFacetDependency ReceptacleDependency

26

Concrete Dependencies:OSGi Unit -> Unit, Application -> Unit

VersionedUnitDependency ImportPackageDependency (OBR)

Eg: the unit requires the package javax.servlet; version=2.3 ImportServiceDependency

Eg: A telnet deamon requires a Shell QualifiedImportServiceDependency ExportServiceDependency

Eg: A command requires a Shell ConsumerWireAdminDependency

Eg: Requires consumers consuming temperatures ProducerWireAdminDependency

Eg: Requires producers producing GPS positions …

Unit -> Site NativeDependency

27

Resolver Parameters

application dependencies site dependencies

Select Units in a UnitRepository According to

application dependencies, site dependencies, unit dependencies And Already deployed units

Return a Process to execute

28

What is missing Configuration

Multi-step ? Pre-installation Post-Installation (according site

attributes)

Manager (OMG D&C) Actor …

29

Interface design issues (i) Interface Attributes could be replace by

javax.management.DynamicMBean - muttable interface + link with JMX and OSMOSE Admin WG

or org.objectweb.fractal.api.control.AttributeCon

troller - muttable interface ? Functional or Non functional interface

or both

30

Interface design issues (ii) Attribute values may be

java.lang.Comparable Eg: Version, VersionedPackage, …

Collection parameters and return Type[] Iterator Iterator<Type> JDK 1.5 and + List/Set List/Set<Type> JDK 1.5 and +

31

Interface design issues (iii) Mutable interfaces

add(Type), remove(Type), … Observable interfaces

Observes if the Unit A changes its implementation version get/set Observer javax.management.NotificationBroadcaster

Finder interfaces Improve performance during dependency resolution Dependency can use those indexes to search Attributes

objects quickly Method find(String filter) ApplicationRepository,

Organization, … Others ?

32

Relationship with other WPs WP2

System Management WP3

Personalities for J2EE, OSGi, CCM Personalities for Fractal

33

Open issues Code/State migration

ProActive ActiveObject Positioning / Compliance with

OMG D&C (Deployment and Configuration of Component-

based Distributed Applications) JSR 88

(J2EE Server API for 3-tier Deployment Tools) Others ?

SUN JNLP, DVB-MHP, Linux RPM, …

34

GDF personalities OSGi J2EE CCM Fractal ProActive DCUP/SOFA Linux .NET Generic

Context Aware, Atonomic, SOA (JINI, WS, OSGi…)

35

The OSGi personality First naïve implementation

Reuse Oscar Bunlde Repository metadata

standalone or as a bundle (on site resolver/deployer)

Should merge with ResolveIT ?

36

Action points We have a deadline : 15 th of july Complete the current GDF

OMG D&C subset or OMG D&C compliance

Share out the work among us Horizontal (process, resolution, …) Vertical (platform)
