Week 15 Notes

What cloud computing really means

The next big trend sounds nebulous, but it's not so fuzzy when you view the value proposition from the perspective of IT professionals

Some define cloud computing as virtual servers

Some say anything produced outside of firewall is in the cloud

Different types of cloud computing:

SaaS has produced “desktop apps” like Zoho office and Google apps.  SaaS uses a multitenant architecture to deliver an application to thousand of customers. 

The customers do not have to pay up front for servers or licensing and providers save money because they only have one app to maintain

Utility computing offers storage and virtual servers that are accessible on demand

Web services in the cloud allow users to take advantage of the functionality of the web with services like xignite, payroll processing, Bloomberg, credit card processing- etc.

Platform as a service allows you to build your own applications that run on the provider's infrastructure and are delivered to your users via the Internet from the provider's servers. Such as Google app Engine and Yahoo Pipes.

Managed Service Providers is an app that is mostly for IT rather than users like virus scanning programs and anti-spam services

Service commerce platforms- most common in trading environments that enable users to order services like travel. Such as Rearden Commerce and Ariba.

Several “bus in the cloud”’s have been created to help intergration.

Thomas Frey. The Future of Libraries: Beginning the Great Transformation

Libraries have traditionally been considered a storehouse for important documents

Initially books were expensive and were often chained in libraries, after the invention of the printing press by Gutenburg and the printing revolution by the Faust son’s this changed.

Andrew Carnegie provided funding for 2,509 libraries.

Information went from scarce and expensive to abundant and often free

Communication changes the way people access information

Books and writing is a technology- technology is always changing and has a limited lifespan.

Eventually the smallest form of storage will be reached.  After that other things will be pursued like findability, durability, realiabilty and speed.

Search engines will become more complicated as the next generation search technology will include the ability to search for such attributes as taste, smell, texture, reflectivity, opacity, mass, density, tone, speed, and volume.

Society expect to receive information more quickly than ever. Libraries will need to adapt to this.

Keyboards will eventually end.

Global information needs will increase.

Patron/customer experience will become the key measurement criteria.
