In one of the most entertaining presentations on the topic ever, Dr. Jim Webber debunks myths about the mainstream ESB concept and explains how a lightweight approach can yield real benefits without giving in to vendor pressure. Jim claims that an ESB often ends up being just a thin veneer on an existing mess, and how an approach that doesn't put intelligence into the network is superior.
Communication is everywhere. The Windows Communication Foundation (WCF) can be used to design and develop service-oriented distributed solutions. This presentation shows the basics of WCF and how to solve common problems in distributed systems. Christian Weyer provides a practical approach to realizing distributed solutions with WCF - beyond the hype and 'Hello World'.
This talk covers the key aspects of the Java Persistence API and its role in the development of EJB 3 app, including use of the EntityManager API, persistence units and persistence contexts, queries, object/relational mapping, and how the combination of EJB 3 and Java Persistence facilitates the development of Java EE applications.
James Cox shows how to keep a Rails site up and running, while keeping performance high. The presentation dives deep into issues of keeping page performance up and avoiding bottlenecks. Next to tips on what to avoid (eg, hostname lookups) and what to do (eg. pre-caching), James also shows situations when to avoid ActiveRecord and fall back to SQL.
In this talk, recorded at QCon London, Mark Nottingham explains how Yahoo! leverages Web technologies, specifically HTTP-based caching using Squid, to create a high-performance architecture for integrating multiple Yahoo! properties, concluding that the Web provides sophisticated techniques without using SOA tooling such as ESBs.
The goal of VSTS is to provide a tool that is not prescriptive and highly customizable for managing the software development process. Kevin Jones provides a soup to nuts framework for utilizing VSTS to support a development team and build better applications. He covers project management, source code control, class designers and various designers available to software architects.
Ever wonder just how Rails declarations such as "has many" and "belongs_to" work? Ever wished you could write your own code that worked the same way? It turns out that this style of programming, often called metaprogramming, is easier than you might think. In this talk we'll see how Ruby's open classes, compile-time execution, and full meta-object model make it easy to write your own extensions.
In this QCon presentation, Amazon.com CTO Werner Vogels explains how Amazon has become a platform provider, and how an increasing number of diverse businesses are built on the Amazon.com platform. Although Amazon.com's scale makes them seem an extreme case, lessons have been learnt that will be of use to every enterprise looking to provide services to or to consume services of business partners.
When we move to distributed architectures for scalability and/or fault-tolerance reasons we are also introducing additional complexities. Amazon CTO Werner Vogels dives into the different parameters that play in the tension between availability and consistency and presents a generalized model that we can use to reason about the trade-offs between different solutions.
Open Terracotta is an open-source, highly scalable, JVM-level clustering solution. As well as being a drop-in replacement for Tomcat Clustering, it can transparently cluster POJOs and Spring beans. This presentation will be an in-depth case study of a small mobile application built using Terracotta clustering.
