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...

Cloud Reliability Will Be Bigger than Cloud Security for 2010-11

Security Sessions at Cloud Expo We have all the tools for securing information in a Cloud: establishing trust through identity, data privacy through encryption, and content integrity through signatures. We are overly focused on Cloud Computing Security  issues and less on reliability. This is all about to change. Following the outages experience by Amazon EC2 in 2009, another premiere cloud provide, Rackspace, suffered an outage on December 18. Using technology such as Forum Systems XML / Cloud gateways is essential for establishing multi-cloud reliability and fault tolerance. ... (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)

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)

Virtues of Service Virtualization in a Cloud

Virtualization Expo on Ulitzer Service virtualization is the ability to create a virtual service from one or more predefined service files.  Service files are usually generated as a Web Service Description Language (WSDL, pronounced Wizdel, see tutorial for introduction to WSDL) file by service containers running business application developed in Java, .NET, PHP type programming languages.  Service virtualization combines and slices business services deployed independent of the operating systems, programming language or hosting location. The services may be off-premise cloud servic... (more)
