In the fall of 2010, the owner of rebus technologies completed his Master's in Applied Computer Science from Columbus State Univeristy. His Master's Thesis Windows Azure: Using Windows Azure’s Service Bus to Solve Data Security Issues detailed how to solve data sercurity issues involved in cloud computing. This thesis has been sited in a wikipedia article on…
Azure Service Bus
The primary purpose of the Windows Azure Service Bus is to relay messages through the cloud in order to support application connectivity. The Service Bus gets its name from the Enterprise Service Bus (ESB) Pattern. This ESB pattern defines a standards based integration model that combines Web Services, data transformation, messaging and intelligent routing. The…
Azure Access Control
The Access Control module of the Windows Azure AppFabric is a claims-based access control in the cloud that provides single-sign on capability to all applications running in the cloud. In addition, this access control module can be used for applications running outside of the cloud. This Access Control module of Windows Azure is accessed using…
SQL Azure
The Windows Azure platform offers the optional SQL Azure database as a supplement to the rudimentary data storage provided by the Storage AppFabric. Unlike the storage appFabric, SQL Azure is a cloud-based relational database that is an extension of Microsoft SQL Server. This multi-tenant, highly scalable database runs in the Azure cloud. This cloud-based database supports the…
Windows Azure Cloud Platform
The Microsoft Windows Azure platform is a Cloud Computing environment that allows customers to run applications and store data in Microsoft data centers around the world. The core of the Azure platform is the Windows Azure cloud-based operating system.

Methods for Protecting Data in the Cloud
The most straightforward method for storing application data may be to store the data in the cloud. The programming model for this method is very close to existing non-cloud development models making it easier to implement. In addition, application performance is usually at a peak with fewer protocol layers and reduced data transfer times. However,…
Issues with storing Data in the Cloud
Moving an application into the cloud offers numerous benefits but it is fraught with security issues. While many of these security issues are related to moving an entire application into to the cloud, this post will focus on issues related to moving an application’s data into the cloud. This outsourcing of data into a Cloud…

Economics of the Cloud
Cloud Computing brings a different economic paradigm to the world of software development. In the past, when a company needed to grow its IT infrastructure it had to make a capital investment in infrastructure. A capital investment refers to the money a business uses to purchase fixed assets, such as servers, routers, and cooling systems….
Virtualization in the Cloud
Cloud Computing is based on the concept of shared server resources. As such, servers running in remote data centers are not dedicated to a single application or customer. Instead, several applications belonging to multiple customers may exist on the same physical server. Conversely, a single application belonging to a single customer may utilize resources from…
