The document proposes a cooperative database caching approach called CoopSC to reduce load on database servers within cloud environments. CoopSC uses a distributed index to share cached query results between clients. It was evaluated using the Wisconsin benchmark dataset on the Amazon EC2 cloud. CoopSC significantly reduced the amount of data transferred and corresponding bandwidth payments compared to no caching. It also improved response times, especially with low update rates. However, performance benefits depended on cloud provider stability.

Tussle analysis helps better understand the interrelations between Future Internet technologies and socio-economics. Its purpose is to study how such stakeholders interact by exploiting Future Internet technologies to advance their economic interests and influence economic outcomes. The presentation will motivate and apply a generic methodology for tussle analysis to the ETICS Approach for Providing QoS-enabled Inter-domain Services.
Fusion-io Memory Flash for Microsoft SQL Server 2012Mark Ginnebaugh
You've heard about Solid State Drives (SSDs), and might be using them now. To get dramatically improved IO performance, you need Flash Memory – storage that can be connected to your server’s Bus, and really maximize IO.
Fusion-io is an industry leader in this area, and Sumeet Bansal explains how to best employ this powerful technology. You'll learn:
* The many ways Flash can help your SQL Server performance, while at the same time lowering costs
* How you can use Flash optimally for your SQL Server deployment
* Easy, low risk ways to introduce ioMemory into SQL Server environments to instantly realize significant benefits.
* How to implement ioMemory optimally for the most pervasive configurations of SQL Server
We are in the midst of a computing revolution. As the cost of provisioning hardware and software stacks grows, and the cost of securing and administering these complex systems grows even faster, we're seeing a shift towards computing clouds. For cloud service providers, there is efficiency from amortizing costs and averaging usage peaks. Internet portals like Yahoo! have long offered application services, such as email for individuals and organizations. Companies are now offering services such as storage and compute cycles, enabling higher-level services to be built on top. In this talk, I will discuss Yahoo!'s vision of cloud computing, and describe some of the key initiatives, highlighting the technical challenges involved in designing hosted, multi-tenanted data management systems.

A CIO is supposed to be able to place their infrastructure in the Cloud and gain
innumerable benefits of which one of them is supposed to be financial. This is what we are
being sold by Cloud Vendors.
Quote from Garry Marsoubian, Director of Data Center Services for MRIS -
“Bill I have a Comprehensive Review that includes: support, security, access, current
costs in licensing, managed services, floor space at current data centers and stretched
the comparison out to 3 years. We also had to consider what components could be
virtualized and if the app vendor like Oracle recognized virtualization
boundaries. And on and on. I am looking forward to this very much. Lots of lessons
learned on what is a fit for Cloud and what is not. “

Communication Patterns Using Data-Centric Publish/SubscribeSumant Tambe
Fundamental to any distributed system are communication patterns: point-to-point, request-reply, transactional queues, and publish-subscribe. Large distributed systems often employ two or more communication patterns. Using a single middleware that supports multiple communication patterns is a very cost-effective way of developing and maintaining large distributed systems. This talk will begin with an introduction of Data Distribution Service (DDS) – an OMG standard – that supports data-centric publish-subscribe communication for real-time distributed systems. DDS separates state management and distribution from application logic and supports discoverable data models. The talk will then describe how RTI Connext Messaging goes beyond vanilla DDS and implements various communication patterns including request-reply, command-response, and guaranteed delivery. You will also learn how these patterns can be combined to create interesting variations when the underlying substrate is as powerful as DDS. We’ll also discuss APIs for creating high-performance applications using the request-reply communication pattern.

Similar to Cooperative Database Caching within Cloud Environments (20)
Internet users are able to reach any server from any access point at any time due to the interconnection and the exchange of IP traffic between about 40,000 different Autonomous Systems. The underlying business model for traffic exchange generates concerns among the network service providers (NSPs), resulting in deadlocks that are challenging the internet ecosystem. We introduce the Sending Party Network Pays (SPNP) model and demonstrate why this model can be considered to be a prerequisite to the deployment of QoS. We also outline ecosystem issues that can be addressed through this model and discuss its limitations.
Seserv workshop alissa cooper - net neutrality practicesictseserv
In the context of net neutrality debates occuring around the world, a central question concerns the extent to which network operators should be free to manage certain Internet applications differently from others. Some stakeholders advocate for regulatory intervention on the basis that this sort of traffic management gives network operators too much power over which applications succeed or fail, while others argue for reliance on competition between network operators to discipline operator behavior. Yet evidence from the UK and the US suggests that the practical reality of how network operators have gone about managing traffic in the last half decade is not entirely consistent with expectations about the disciplining power of either regulatory or competitive forces in the marketplace. Understanding why Internet traffic ultimately gets managed in a particular way requires a deeper understanding of the interplay between technical, economic, political, and social dynamics confronting network operators.

Epistemic Interaction - tuning interfaces to provide information for AI supportAlan Dix
Paper presented at SYNERGY workshop at AVI 2024, Genoa, Italy. 3rd June 2024
https://alandix.com/academic/papers/synergy2024-epistemic/
As machine learning integrates deeper into human-computer interactions, the concept of epistemic interaction emerges, aiming to refine these interactions to enhance system adaptability. This approach encourages minor, intentional adjustments in user behaviour to enrich the data available for system learning. This paper introduces epistemic interaction within the context of human-system communication, illustrating how deliberate interaction design can improve system understanding and adaptation. Through concrete examples, we demonstrate the potential of epistemic interaction to significantly advance human-computer interaction by leveraging intuitive human communication strategies to inform system design and functionality, offering a novel pathway for enriching user-system engagements.

Neuro-symbolic is not enough, we need neuro-*semantic*Frank van Harmelen
Neuro-symbolic (NeSy) AI is on the rise. However, simply machine learning on just any symbolic structure is not sufficient to really harvest the gains of NeSy. These will only be gained when the symbolic structures have an actual semantics. I give an operational definition of semantics as “predictable inference”.
All of this illustrated with link prediction over knowledge graphs, but the argument is general.
