CLOUD COMPUTINGTrends to Watch for Libraries

One of the major transitions in technology involves increased adoption of computing models that involve use of hardware and software outside the library. It’s a seminal technology change as important as the shift from mainframes to client/server architectures. We’re hearing more about application service providers, software-as-a-service, storage-as-a-service, and platform-as-a-service. How does OCLC’s global WorldCat platform fit into the mix? What is the difference between public and private clouds? What are the issues for libraries in the deployment of cloud computing in terms of cost, efficiency, privacy, control, and security? Marshall Breeding clarifies the concepts of cloud computing with examples of interest to libraries.
Continuum of Abstraction
Locally owned and installed servers Co-located servers Co-located virtual servers Web hosting Server hosting services Application Service Provider Software-as-a-service Infrastructure-as-a-service Platform-as-a-serviceThe Advance of Computing From the Ground to the CloudComputers in Libraries, December 2009http://www.librarytechnology.org/ltg-displaytext.pl?RC=14384
What is Cloud computing?
Wikipedia:
“Cloud computing is Internet-based computing, whereby shared resources, software, and information are provided to computers and other devices on demand, like the electricity grid.”
“Cloud computing is a new approach that reduces IT complexity by leveraging the efficient pooling of on-demand, self-managed virtual infrastructure, consumed as a service”
Cloud computing used very freely, tagged to almost any virtualized environment
Any arrangement where the library relies on some kind of remote hosting environment for major automation components
Includes almost any vendor-hosted product offering
Cloud computing – characteristics
Highly abstracted computing model Utility model Provisioned on demand Scaled according to variable needs Discrete virtual machines Compute cycles on demand Storage on demand Elastic – consumption of resources can
contract and expand according to demand
Fundamental technology shift Mainframe computing Client/Server Cloud Computing
Private – cloud architecture, institutionally controlled Enforces physical segregation Leverages cost and scalability Institutions may require private clouds from
providers Institutions may operate their own cloud
infrastructure for internal clients
Library automation through SaaS Almost all library automation products
offered through hosted options Saas or ASP?
ILS Products offered as SaaS SirsiDynix Symphony SirsiDynix Horizon Innovative Interfaces Millennium Ex Libris Aleph EOS International EOS.Web Evergreen – Equinox Software Koha – LibLime, ByWater, many others
