Large-Scale Agile Design & Architecture: Ways of Working
During my 2011 QCon London keynote on "Scaling Lean & Agile: Large, Multisite or Offshore Delivery", I mentioned — as an aside — that, "Architecture is a bad metaphor. We don't construct our software like a building, we grow it like a garden." This prompted many a tweet, and some people were interested in clarification or elaboration.

Concurrency Controls in Data Replication
Learn about leading concurrency control mechanisms used for data replication in distributed environments, comparing synchronous and asynchronous implementations with/without locking - techniques used by Oracle RAC, TimesTen, and GigaSpaces and NoSQL databases. Explore tradeoffs among performance, consistency, deadlocks, and conflicting updates in the context of a sample distributed application.

The Azul Garbage Collector
Azul's recently announced Zing product brings their Garbage Collector, which achieves both pauseless garbage collection and a high tolerance to the factors which typically impact collection and application responsiveness, to Java programs running on Intel and AMD based servers. This article takes a detailed look at how Azul has been able to achieve these design goals.

Infinispan's GridFileSystem - An In-Memory Grid File System
Infinispan is an open source data grid platform that makes use of distributing state across nodes in a cluster. GridFileSystem is a new, experimental API that exposes an Infinispan-backed data grid as a file system. In this article, authors discuss distributed mode of Infinispan and how GridFS framework manages data caching by chunking up data using a new streaming API and storing them in a grid.

Extreme Transaction Processing Patterns: Write-behind Caching
Lan Vuong shows how to optimize the performance of an application by leveraging the write-behind caching pattern which sends batch updates to the back-end database asynchronously within a user configurable interval of time, instead of doing sychronous write-through updates typical in web apps.

Performance Analysis and Monitoring with Perf4J
In this article Alex Devine explains how Java developers can take advantage of Perf4J, an open source toolset for adding code timing statements and for logging, analyzing and monitoring the results. Alex introduces several aspects of Perf4J like integration with Log4J, use of annotations, pitfalls and good practices.

Gregg Pollack and the How-To of Scaling Rails
Ruby on Rails has done well since its introduction a few years ago but has taken some criticism for not being able to scale. Developers know there is always a right way and a wrong way to solve any problem and scaling Ruby on Rails is no different. Learn about what is being done to address Ruby on Rails and scaling to the enterprise.

A Formal Performance Tuning Methodology: Wait-Based Tuning
In this article, Steven Haines talks about web application performance tuning which used to be more of an art than science. He proposes a method called wait-based tuning, making the entire process more measurable and, consequently, more scientific.
