  1. A novel Portal Architecture for Real-Time Online Interactive Applications on the GridChristoph Anthes, Roland Landertshamer, Roland Hopferwieser, and Jens VolkertCracow Grid Workshop ‘07 • Dipl. Inf. (FH), MSc • Christoph Anthes • 16.10.07

  2. Overview • Introduction • Common Grid Portals • The edutain@grid project • Business portal • Management portal • Portal API • Conclusions and Future Work A novel Portal Architecture for Real-Time Online Interactive Applications on the Grid

  3. Introduction • Classical Grid Applications • Traditionally Batch Processing • Jobs are submitted results are returned after processing • In recent years focus is shifting into interactivity • Examples: CROSSGRID, gVid, gLogin, etc. • Real-Time Online Interactive Applications (ROIAs) • Applications from the field of e-Learning and Multi-user games • Different needs considering interactivity • Low latencies, high bandwidth, high amount of concurrent users interacting with one job • ROAIs call for services which the Grid can offer • QoS • Automatic provision of resources • Virtual organisations • Load balancing etc. A novel Portal Architecture for Real-Time Online Interactive Applications on the Grid

  4. Grid Portals • Typical Grid Tools • Portals are typically web based user interfaces which aggregate information from one or more sources and allow interaction with grid resources • Portal Frameworks • Gridsphere, Jetspeed • uPortal, LifeRay, jPortlet, PGrade Firewall Client e.g. browser Front-end e.g. Web server Back-end e.g. Web or Grid services Grid services on remote server CGI over http(s) Web Service Grid Service A novel Portal Architecture for Real-Time Online Interactive Applications on the Grid

  5. The edutain@grid Project • http://www.edutaingrid.eu/ • 7 Partners (UIBK, GUP, UM, IT Innovation, BMT, Darkworks, AMIS) • Duration: 36 months (01.09.2006 – 31.08.2009) • 3 different layers in the architecture • Different communication methodology inside and in-between the layers (e.g. web services, socket communication) • Support of legacy applications • Main differences to traditional Grid computing • Job which is started is an application server • Direct communication between job and users is allowed A novel Portal Architecture for Real-Time Online Interactive Applications on the Grid

  6. Different Layers of edutain@grid • Business Layer • Account management • SLAs • QoS • Supports variety of actors • Management Layer • Resource allocation • Monitoring • Capacity management • Real-Time Layer • Distribution of the virtual environment A novel Portal Architecture for Real-Time Online Interactive Applications on the Grid

  7. Different Layers of edutain@grid • Real-Time Layer • Zoning: MMORPG, ((MMO)FPS, (MMO)RTS) • Instancing: MMORPG, ((MMO)FPS, (MMO)RTS) • Replication: (MMO)FPS, (MMO)RTS Slide from Jens Mueller-Iden A novel Portal Architecture for Real-Time Online Interactive Applications on the Grid

  8. edutain@grid Portals • Defining portals for edutain@grid • Mainly seen as user interfaces • Can provide a composition of the information of several layers or sources of one layer • Access to one or more layers • Not necessarily based on web-services • Do not use only use web browsers for the user interface • Edutain@grid portal types • Web portals (based on Gridsphere) • Portal API (C++ API) • Portal application (C++ Client implementing a GUI for the portal API) • Similar approach to server browsers A novel Portal Architecture for Real-Time Online Interactive Applications on the Grid

  9. Business portal • Functionality • Login possibilities for different actors (Consumers, Providers, etc.) • Authentication via encrypted tokens • Different functionality depending on role • SLAs can be formed • Used for account and system management • Acts as a community portal for consumers (comparable to Steam, Gamespy, battlenet) • Implementation • Mainly implemented by GRIA • Connection via web services A novel Portal Architecture for Real-Time Online Interactive Applications on the Grid

  10. Management portal • Direct connection to the management layer • Functionality • Administration of local infrastructures • Allows manual starting and shutdown of servers • Deployment of patches and applications on a hoster side • Debugging of deployed edtuain@grid applications • Application Monitoring • Capacity Management Monitoring • Monitoring visualisation • Implementation • Runs locally at the hosters site • Based on Gridsphere • Java Applets for Visualisation • Connection via RMI or alternatively web services to management host A novel Portal Architecture for Real-Time Online Interactive Applications on the Grid

  11. Management portal • Connection to the management layer controlling Management Portal monitoring https WebServices/ RMI Management Host Portal Server TCP Sockets RMI ROIA Server ROIA Server ROIA Server A novel Portal Architecture for Real-Time Online Interactive Applications on the Grid

  12. Portal API • Connection between client applications and the three layers of the edutain@grid architecture • Functionality • Login mechanism on the business layer via tokens connection forwarded to the management layer and the real-time layer • Used for client-side connection to edutain@grid system • Look-up service for game or e-learning sessions (server browsing) • Implementation • Implemented in C++ • Connection via Web Services and TPC sockets • Axis2 for login and connection to Business layer A novel Portal Architecture for Real-Time Online Interactive Applications on the Grid

  13. Conclusions and Future Work • Conclusions • Different needs in Grid applications need different types of portals • Real-time interactive applications need portals which allow real-time interactive visualisations • Direct real-time communication with the jobs will become more and more necessary • Future Work • Further implementation of the Portal API and the Web Portals resulting in a portal framework • Portal framework will provide a structured approach to advanced real-time control of Grid applications A novel Portal Architecture for Real-Time Online Interactive Applications on the Grid
