Introduction to Cloud Security Architecture from a Cloud Consumer's Perspective
Security concerns are the number one barrier to cloud services adoption. How do we evaluate a vendor's solution? What is an optimal security architecture? What are consumer versus provider responsibilities? What are industry standard patterns in this regard? This article answers some of these questions based on first hand experience dealing with large scale cloud adoption.

Exploring Hadoop OutputFormat
As more companies adopt Hadoop, its integration with other applications is becoming more important. A key to such integration is usage of the appropriate OutputFormat allowing to produce output data in a form most appropriate for other applications.

Trust is good, Control is better - Software Architecture Assessment
Testing is an important means to obtain information about implementations. Likewise, code reviews help to keep the code quality high. What is very common for code, gets sometimes neglected for software architecture. But how can a project team test the architecture itself? Software architecture assessment represents an effective approach for introspecting and assessing software design.

Comparison of Intrusion Tolerant System Architectures
In this IEEE article, authors Quyen L. Nguyen and Arun Sood discuss three types of intrusion tolerant system (ITS) architectures and their efficiency for intrusion tolerance and survivability. For the ITS architectures, they propose a taxonomy with four categories: detection triggered, algorithm driven, recovery based, and hybrid.

Virtual Panel: Cloud Services Governance
Governance plays an indisputably important role in maintaining and guiding the implementation of an architectural vision. The advent of cloud computing has changed the architectural landscape affecting the needs and demands of existing governance programs. InfoQ presents a virtual panel discussion with six leading experts on the current state and future of cloud services governance.

Enterprise Shared Services and the Cloud
As an industry, we have converged onto a standard three-layered service model (IaaS, PaaS, SaaS) to describe cloud computing, with each layer defined in terms of the operational control capabilities it offers. This is unlike, enterprise shared services, which have unique characteristics around ownership, funding and operations, and they span SaaS and PaaS layers, as we explore the differences.

Virtual Panel: Security Considerations in Accessing NoSQL Databases
NoSQL databases offer alternative data storage options for storing unstructured data compared to traditional relational databases. Though the NoSQL databases have been getting a lot of attention lately, the security aspects of storing and accessing NoSQL data haven't been given much emphasis. This article focuses on the security considerations and best practices in accessing the NoSQL databases.

Developer-Driven Threat Modeling
Threat modeling is critical for assessing and mitigating the security risks in software systems. In this IEEE article, author Danny Dhillon discusses a developer-driven threat modeling approach to identify threats using the dataflow diagrams.

Moving Channel9.msdn.com to Windows Azure
Imagine if architects had to be the janitor for every building they designed. With an understaffed Channel 9 development team handling production support on a web farm built from mismatched servers, something had to be done. When Windows Azure was launched in the summer of 2010 the development team saw it as a way to hand off support and return to building features.

Interview and Book Review: Documenting Software Architectures: Views and Beyond, 2nd Edition
The book "Documenting Software Architectures: Views and Beyond" covers the software architecture documentation and how to express an architecture so that the developers can design, build and maintain a system from it. InfoQ spoke with Paulo Merson, co-author of the book on software architecture documentation and how it can help the design of software applications.

How REST replaced SOAP on the Web: What it means to you
The number of REST APIs has grown dramatically over the last 5 years. However, most developers are still struggling to find an agreed upon definition of a RESTful Architecture leading to a lot of inconsistencies in the way these APIs are implemented. This article details how Mule iON, an Integration Platform as a Service, provides a consistent way to expose APIs and API mashups.
