Search</p><p> View</p><p> What new services? Information mining</p><p> Advanced queries</p><p> Semantics</p></li><li><p>Services [Solution]</p><p> Services can be easily created in the correct frameworks Cloud-Computing</p><p> Built-in framework</p><p> Easy development of new services</p><p> Increases momentum in the developer community</p><p> Faster testing and deployment</p><p> More processing power</p></li><li><p>Digital Data Storage [Problem]</p><p> Digital data Preservation</p><p> Component failures</p><p> Obsolescence</p><p> Attacks</p><p> Natural disasters</p><p> Distribution</p><p> Availability</p><p> Heterogeneity</p><p> Scalability</p><p> Authenticity</p></li><li><p>Digital Data Storage [Solution]</p><p> Preservation issues may be solved with distributed environments Cloud-computing</p><p> Built-in architecture</p><p> Distributed</p><p> Every single data bit is replicated</p><p> Metadata</p><p> Geographic distribution Scalability</p><p> Better availability is assured</p></li><li><p>Cloud Libraries [Conclusions]</p><p> Information is the most important component We shouldnt care about anything else</p><p> Leave that to the cloud-computing environment</p><p> Service development</p><p> Distributed architecture</p><p> Metadata</p><p> Digital libraries and cloud-computing are a perfect match Create a digital library based on a cloud computing operating environment</p><p> Microsoft Azure Services</p><p> Amazon Elastic Compute Cloud</p><p> Google App Engine</p></li><li><p>Questions?</p></li><li><p>Thank You</p></li></ul>
