3. 3 Architecture of StratusLab v1.0 IaaS Cloud Virtual Machine Manager (OpenNebula) XML-RPC  OCCI Physical Computing Resources VMware Service Manager (Claudia) TCloud Storage Manager REST/CDMI iSCSI (?)KVMXen… Physical Storage Resources … Appliance Management StratusLab Marketplace HTTP(S) REST Interface Appliance Storage (Web, Grid, Cloud) users

4. 4 Virtual Machine Management OpenNebula improvements  More complete logging information  Quarantine of stopped images  Ability to pass error messages from plugins to user (soon)  Support for users, groups, and roles (soon) PXE Booting  Useful for integration with automated machine mgt. (Quattor)  Useful for automating creation of base/user images Collaboration  StratusLab  OpenNebula  Others: general improvements  StratusLab  Others: Automated machine creation

5. 5 Networking IP  IPv6 use/validation  Public/local/private IP addresses  IP address selection (useful for grid services)  IP reservation (à la Elastic IP) Dynamic configuration  VLANs  User-specified firewalls Collaboration  SARA, Mantichore  StratusLab: dynamic configuration  StratusLab  ?: IPv6  StratusLab  Others: IP reservation, address selection

6. 6 Storage Persistent Disk Store  Prototype exists, production in v0.4  Based on iSCSI and LVM Caching/Latency Reduction  Investigating Ceph, LVM  Hierarchical (squid?) caches Interfaces  CDMI Collaboration  VENUS-C  StratusLab: CDMI proxy, integration with data mgt.  SARA, SNIA  StratusLab: CDMI reference/SARA implementation  StratusLab  Others: caching and latency reduction

7. 7 Marketplace Appliance Repository (phasing out)  Essentially a webdav server with specific layout  Stores both metadata and image contents Marketplace (phasing in)  Registry of image metadata  Contents stored in cloud, grid, web, … Collaboration  StratusLab  HEPiX: Metadata definition, signing, validation  StratusLab  HEPiX: Interoperability of image catalogs, registries  StratusLab  HEPiX: Policy definition and enforcement

8. 8 Appliances Base images  ttylinux, CentOS 5.5, Ubuntu 10.04, OpenSuSE (?) Grid appliances  CE, SE, WN, APEL/BDII, UI Bioinformatics appliances  Data server and analysis images Collaborations  StratusLab  EGI, EMI, EDGI, user communities: Collaboration on creating and testing of applicances

9. 9 Authn/Authz Implementation  Authn proxy in front of ~all services  Uses Jetty implementation of JAAS  Supports User/Password files, LDAP, Grid certificates, VOMS proxies  Passed authn information to back-end services  Delegation currently not used Collaborations  StratusLab  EMI: Feedback Jetty support, other changes  EMI  StratusLab: Better packaging, portable voms-proxy-init, delegation service

10. 10 Service Manager (Claudia) Implementation  Provides service (ensemble of machines) management  Dynamic control based on monitoring feedback  Currently being integrated with other StratusLab services Collaborations  StratusLab  VENUS-C, Others: Possibly interesting component for building platforms, "canned" services  StratusLab  Others: OVF and TCloud implementations

11. 11 Accounting Monitoring Implementation  Simple script to extract values from database  No publication of the information at the moment Collaborations  VENUS-C  StratusLab: Use/integration of accounting service  StratusLab  EGI: Integration with EGI accounting, types of resources for accounting

12. 12 Conclusions StratusLab Release(s)  Nearly complete, functional beta available  Used to run production grid site over reference infrastructure  Complete beta (v0.4) end of April  Production release (v1.0) end of May Collaborations  Looking forward to collaborations with other projects  Software can be tested on reference infrastructure or installed  Want feedback (positive and negative) from user, admins, …
