Stateless Computing

A few days ago I read a review of Merrill Lynch's Jeffrey Birnbaum LinuxWorld keynote on stateless computing.

"With stateless computing, users' settings and data are automatically saved to the server, which could be run by their employer or outsourced. Cloud computing generally refers to technology that lets people use Web browsers to access applications running on central servers, though it also can refer to general-purpose server infrastructure that companies can tap into as needed."

This mean that the cloud will continually hold our current computing state, ready to support us via whatever network or device we connect with. It also means that the cloud may need to hold multiple states to match the possible permutations of devices, networks, applications, etc. that we may connect with. All those states would also need to be available for transfer between the multiple public and private clouds that we may use. And don't forget the need to maintain privacy and security for us all.

Whew. Makes my head hurt.

Hacking Into The Indian Education System Reveals Score Tampering

Image
Debarghya Das has a fascinating story on how he managed to bypass a silly web security layer to get access to the results of 150,000 ISCE (10th grade) and 65,000 ISC (12th grade) students in India. While lack of security and total ignorance to safeguard sensitive information is an interesting topic what is more fascinating about this episode is the analysis of the results that unearthed score tampering. The school boards changed the scores of the students to give them "grace" points to bump them up to the passing level. The boards also seem to have tampered some other scores but the motive for that tampering remains unclear (at least to me). I would encourage you to read the entire analysis and the comments , but a tl;dr version is: 32, 33 and 34 were visibly absent. This chain of 3 consecutive numbers is the longest chain of absent numbers. Coincidentally, 35 happens to be the pass mark. Here's a complete list of unattained marks - 36, 37, 39, 41, 43, 45, 47, 49, 51, 53,...

Information Service and Cloud Dedicated Hosting

Image
Dedicated hosting service, dedicated server, or managed hosting service is a type of internet hosting the client leases an entire server not shared with anyone. It is more flexible than shared hosting, and organizations have full control over the server (s), including choice of operating system, hardware, etc. There is also another level of dedicated or managed hosting managed hosting is called complex. Apply complex managed hosting on physical servers, hybrid server and virtual servers with many companies choose hybrid (a combination of physical and virtual) hosting solution. There are many similarities between the standard and complex managed hosting, but the main difference is the level of administrative support and engineering the customer pays for all because of the growing size and complexity of infrastructure deployment . Steps presented to support most of the administration, including security, memory, storage, and support of information technology. Proactive ser...

IBM's Blue Cloud Meets Juniper To Alleviate Cloud Computing Adoption Fears

Security and lack of an acceptable SLA are customers' top adoption fears to move to cloud computing . IBM's recent announcements to further advance their cloud computing initiative known as Blue Cloud should help alleviate these fears to some extent. IBM announced their partnership with Juniper for their hybrid cloud initiative to provide secured private cloud with better SLA. IBM also announced new offerings for the cloud - Tivoli storage as service and a new set of cloud management tools to align with what a typical CIO would look for when migrating to the cloud. In addition IBM is pushing some of their existing offerings on the cloud that customers can now use off Amazon's EC2 on pay-as-you-go subscription model . IBM has been experimenting with the concept of a private cloud for a while. One of such experiments included creating a private virtual cloud inside the firewall to deploy some of the regions of SecondLife with seamless navigation in and out of the firewall....
