Cloud Computing Infrastructure on Demand from Amazon, Google, MS “Suffer from Regular Performance and Availability Issues…08.20.09

This is interesting and possible disturbing to some enterprise cloud computing clients as Australia’s ITNews reports:

“Stress tests conducted by Sydney-based researchers have revealed that the infrastructure-on-demand services offered by Amazon, Google and Microsoft suffer from regular performance and availability issue.

The team of researchers…spent seven months stress testing Amazon’s EC2, Google’s AppLogic and Microsoft’s Azure cloud computing services…

The research found some merit to vendors’ claims of ‘perceived infinite scalability.

But researchers also found that the three platforms delivered wildly variable performance results as Amazon, Google and Microsoft trialled, added and dropped new features.

Response times on the service also varied by a factor of twenty depending on the time of day the services were accessed, she said…”





Cloud Computing Risks to Consider…07.29.09

LifeHacker’s The Hidden Risks of Cloud Computing lists 4 potential serious risk of using cloud computing:

” Every day more users move their computing lives from the desktop to the cloud and rely on hosted web applications to store and access email, photos, and documents. But this new frontier involves serious risks that aren’t obvious to most…

Lesser Privacy Protection Under the Law…

Weak Security Systems That Are Too Easy to Break Into…

Data Lock-in and Third-party Control…

Server Unavailability and Account Lockout…

…The key is to know what you’re getting into when you make that choice, to ratchet up your personal security mechanisms (like alternate email addresses and password choices) and to lobby for better user protection by hosting providers in the cloud…”





Library of Congress Enters Era of Cloud Computing…07.21.09

CNET reported today:

The Library of Congress National Digital Information Infrastructure and Preservation Program and DuraSpace have announced that they will launch a one-year pilot program to test the use of cloud technologies to enable perpetual access to digital content.

The pilot will focus on a new cloud-based service called DuraCloud, that replicates and distributes content across multiple cloud providers and enables organizations to share, access, and preserve said content. Eventually the service will also provide computing capabilities in addition to the storage and archiving functions. (DuraSpace is a joint effort of the Fedora Commons and the DSpace Foundation.)

The project started with a vision of federated repositories and infrastructure that would scale massively and remove the risks of data silos. The other major goal is to make the service usable across external and internal cloud deployments…”

OCLC’s Cloud Computing for Libraries – Ramifications…06.10.09

OCLC seems to jump from one pan on the fire to the next this year. Let me point out below the Library 2.0 gang post Library System Suppliers View of OCLC Web-Scale about their most recent interesting podcast about another recent and potentially controversial announcement. It is worth a listen when you find the time.

“In last month’s show there was some speculation as to what reaction there would be from the organisations that supply ‘traditional’ library systems to the OCLC announcement of their web-scale, cloud computing, library system initiative.

In an attempt to answer that speculation I took the unusual step of bringing together a specific set of Library 2.0 Gang members from that community as against our usual open house of whoever is available.  The result was an interesting conversation between Ex Libris’ Carl Grant, Nicole Engard from LibLime, Talis’ Rob Styles and newcomer from Axiell, Boris Zetterlund…”

Libraries and Cloud Computing…05.19.09

This is an excerpt from Lorcan Dempsey from his post The Library of the Future in which he discusses libraries and cloud computing:

“…We have seen a major shift to webscale which has reconfigured whole industries as well as individual organizations… 

At the same time the web has accelerated the vertical disintegration of firms and the sourcing of capacity with specialist providers. Think historically of payroll, or more recently of customer relationship management and SalesForce.com. A wide range of capacities may be sourced externally: think of anything from data centers, to the provision and care of plants, to education and counselling services. Companies make decisions about what their distinctive capacities are, and externalise other capacities to networks of providers and partners. And, in fact, effective supply chain management has become an important competitive factor.

These types of questions are becoming more important for libraries, even if they don’t pose them in quite these terms. And they are not especially new. Historically, for example, think of two major shifts: shared cataloging/resource sharing and the move to licensed access to A&I databases and e-journals. In the former case, activity was externalised to consortial activity or to national-scale organizations, and today many organizations provide such services around the world, including OCLC. In the latter case, libraries gave up the institution-scale management of the A&I and journal resources they had collected in print form. They externalized this activity to, often commercial, third parties.

What Dahl does in this presentation is to look at the future of the library in the context of the reconfiguring potential of network services. He talks in general terms and then offers specific examples. He suggests that the library may become smaller, may shift to new service areas, and may become more creative in the work it does. What I especially like about it is that he acknowledges that organizational change is an appropriate response and then works through what this might mean in practice.”

Personal Cloud Computing With a Twist – ZumoDrive…05.16.09

16 05 2009

Here is an excerpt of a MakeUseOf.com post ZumoDrive – Cloud Storage Service With A Twist about another option for personal cloud computing which is worth checking out:

zumodrive-logo“By now, you should have heard of some of the popular cloud storage services such as DropboxSugarsync,Box.net etc. Recently, there is another kid on the block and I think it is worth the mention at MakeUseOf.

ZumoDrive is an online storage service that everyone can use to store their files in the Cloud and access them from different computers. What makes it different from the rest of its competitors is the way it manages the data on your computer. Most storage services create a folder on your local hard drive and sync all of the data to/from that folder. This might be a good idea in order to keep the data in sync, but what if you are using a 4GB Netbook and you have 10GB of data in the cloud? Your Netbook won’t be able to hold all the data.

What ZumoDrive does is: mount itself as a drive on the computer and “tricks” the computer into thinking that the hosted data are local. When you click to open any file (or music) from ZumoDrive, it will stream those files from the cloud and open them with any local application. This way, even if you are running out of hard disk space, you can still access 10GB (or even 500GB) of data from your computer effortlessly…”
