Secure Cloud Computing on Ulitzer Security in the Ether, by David Talbot MIT Technology review recently published a great article titled: Security in the Ether addressing security, privacy and reliability issues resulting from cloud computing. Some of the interesting points in this article include: The cloud security threat is across two related dimensions: i) cloud resident data may be lost due to equipment/software failure or stolen by a hacker because of the shared resouce nature of cloud computing and ii) cloud data may be mishandled by the cloud provider because of technology gaps, but more importantly, such information can be extracted through a court issued subpoena.  Whether the data resident in the cloud versus on-premise makes it more or less likely to a subpoena being exercised is yet to be seen.  Bit and bytes lost accidentally or intentionally have a st...

Understanding Cloud Taxonomies and Security

XML Security at Cloud Expo OWASP AppSec DC 2009 had a compelling session that defined cloud taxonomies and the security implications associated with the cloud computing. The three taxonomies that have become part of our vernacular are: Infrastructure as a Service (IaaS): Set of virtualized components that can be assembled to build a application.  Amazon EC2, Rackspace, Opsource, and GoGrid are examples of IaaS where you can rent "virtual" hardware and software as a "pay-as-you-go" services.  If you need 5 Linux servers running MySQL Database for 3 months, you'd subscribe to an Iaa...

Support Real Healthcare Reform: Start Using HL7 v3

Health Care at Cloud Expo We all know that technology is key to reducing health care costs, eliminating dangerous errors, and eventually providing coverage for all.  I like learning from others, so while we consider ourselves innovative, there is no point in repeating mistakes made by others.  Here's a fact motivating the Dutch -- one of the leading nations in using modern technology (SOA, XML. HL7v3, Schematrons, Virtualization, Cloud computing) for solving their heath care problems: "Currently some 90.000 people (out of a population of 16 million) are hospitalized yearly due ... (more)

Using SQL Azure for SOA Quality Testing

I. INTRODUCTION Throwing its hat in the Platform as a Service (PaaS) ring, Microsoft has joined the likes for Salesforce.com and Google with its annoucement of Microsoft Azure Platform. Microsoft Windows Azure Platform provides three primary components: Windows Azure: A cloud services operating system that serves as the development, service hosting and service management environment for the Windows Azure platform. SQL Azure: A cloud hosted relational database that removes the burdens of RDBMS installation, patching, upgrades and overall software management for relational databas... (more)

Federated SOA: A Pre-Requisite for Enterprise Cloud Computing

According to Massimo Pezzini, VP and Gartner Fellow, "Federated SOA is a systematic approach to large-scale, enterprise wide SOA that enables organizations to integrate semi-independent SOA initiatives. Often used to fix an initial lack of coordination, federated SOA should be proactively pursued from the inception of major, strategic SOA initiatives." -- Divide and Conquer: Taming Complexity Through Federated SOA. Successful enterprise SOA implementations build on a set of localized, project-level efforts with services that have clearly identified and accountable business and te... (more)
