News: Information about student scholarships has been posted on the registration page. We are also proud to invite all registered students on the LADIS dinner cruise on Friday September 2. More details will be sent by e-mail.

LADIS 2011 will bring together researchers and practitioners in the fields of distributed systems and middleware to discuss the challenges of building massive distributed computing systems and clouds. By posing research questions in the context of the largest and most-demanding real-world systems, the LADIS workshop serves to catalyze dialog between cloud computing engineers and scalable distributed systems researchers, to open the veil of secrecy that has surrounded many cloud computing architectures, and to increase the potential impact of the best research underway in the systems, database and theory communities.

Due to the co-location with VLDB, this year's LADIS will devote special attention to promoting exchange of ideas between the database and systems communities on the topics related to design, implementation, performance and underlying principles of large-scale distributed systems and cloud computing. The workshop is now in its 5th iteration, and was co-located with SOSP and PODC in the past two years.

LADIS invites work and promotes the exchange of ideas in the following topics:

• Consistency, reliability and fault-tolerance models for cloud computing infrastructures and the technologies to support them (e.g. convergent consistency, transactions, state-machine replication).
• Novel storage organizations for large scale systems (e.g., NoSQL databases, key-value stores, intelligent caches), snapshot and weak isolation models, scalable and elastic transaction approaches (e.g. mini-transactions), wide-area transactions.
• Large-scale infrastructure technologies (e.g. Chubby, Paxos, Zookeeper, group membership services, distributed registries).
• Support and programming models for scalable cloud-hosted applications and services (e.g. map-reduce, global file systems, pub-sub, multicast, group communication).
• Power and other resource management tools (e.g. virtualization and consolidation, resource allocation, load balancing, resource placement, routing, scheduling).
• Privacy tools and models (e.g. digital identity management, encrypting private data in the cloud, information flow in data centers).

Particular attention is given to challenges unique to the large-scale distributed systems and cloud computing domains. The workshop will last for two days on September 2-3, which will include a mix of presentation of accepted papers and as well as keynotes from prominent industry speakers who have been there, made key decisions, and can talk about the architectures of the world's most demanding cloud platforms.

Previous LADIS keynote and invited speakers include:

• Amazon: Marvin Theimer (Principal Engineer)
• eBay: Franco Travostino (CTO) and Randy Shoup (Chief Architect).
• Google: Jeff Dean (Google Fellow), Tushar Chandra
• HP: Norm Jouppi (HP Fellow)
• IBM: Gennaro Cuomo (CTO, IBM WebSphere), Chet Murthy (previously at Twitter)
• Microsoft: David Nichols (Windows Live), James Hamilton (technology guru for Microsoft's Cloud Computing initiative, now at Amazon)
• SAP: Burkhard Neidecker-Lutz (Technical Director of Research)
• Telefonica Research: Pablo Rodriguez-Rodriguez (Scientific Director)
• Yahoo!: Raghu Ramakrishnan (Yahoo! Fellow), Ben Reed (developer of Yahoo's Zookeeper),

Important Dates

• Notification: July 15
• Camera-ready due: July 29
• Workshop Date: September 2-3

Submission and Logistics

To attend, you are invited to submit a position or short research paper expressing new ideas, research directions, or relevant opinions. Submissions consist of up to 5 pages using 11-point Times Roman font, including title page with author names, and bibliography. Submissions deviating from these guidelines will not
be reviewed. Submissions will be judged on originality, clarity, relevance, and, above all, their likelihood of generating discussion. Accepted papers will be included in the VLDB workshop proceedings.

Submission will be handled by EasyChair. Please use the following submission site:
