Cameron Purdy explains how a data grid functions by using a partition topology for data access, update, recovery and local storage, accessing data using read/write-through and write behind, and invoking operations through Observable, QueryMap and InvocableMap interfaces. He also offers some examples of data grids solving complex problems and introduces Coherence, Oracle’s data grid solution.
Brian Oliver explains what the Reconciliation Process is, why the current approach to reconciliation based on client-server is no longer suitable and how data grids and event based reconciliation might help.
Ulf Wiger shows typical Erlang programs, patterns that scale well on multicore and patterns that don't, profiling and debugging parallel applications and ensuring correct behaviour with QuickCheck.
In this presentation, recorded at QCon San Francisco, ThoughtWorks' Ian Robinson explains how a RESTful HTTP approach can be applied in an Enterprise project. He makes use of many of the techniques that make HTTP a powerful protocol, including caching, hypermedia, and the use of standard formats such as Atom Syndication for event notification.
HTTP is one of the most successful protocols in the world, and more and more developers are using it to do more than drive HTML UIs. In this presentation, recorded at QCon San Francisco 2008, HTTPbis WG chair Mark Nottingham gives an update on the current status of the HTTP protocol in the wild, and the ongoing work to clarify the HTTP specification.
In this presentation filmed during QCon SF 2008, Aditya Agarwal discusses Facebook’s architecture, more exactly the software stack used, presenting the advantages and disadvantages of its major components: LAMP (PHP, MySQL), Memcache, Thrift, Scribe.
In this presentation, recorded at QCon London, Stefan Tilkov introduces the key principles of REST, explaining the differences to other distributed systems architectures and highlighting its benefits. Topics covered include mapping business logic to resource interactions, hypermedia, and documentation.
In this presentation from RubyFringe, Tobias Lütke talks about memcached, the widely used caching solution. Tobias explains how to use it and gives some practical tips on what not to do.
In this presentation, Jinesh Varia, a Web Services Evangelist at Amazon, talks about the architecture of one of Amazon's web services called Alexa. Jinesh explains how Amazon has reached scalability, performance and reduced costs for the Alexa service.
In this presentation, Cameron Purdy discusses Java scaling. Topics include performance improvement versus scaling improvement, serial bottlenecks, queue theory, rewriting existing frameworks, avoiding the database, single points of failure, avoiding abstractions, disaster recovery, one-size-fits-all architecture, large JVM heaps, network failures, and trusting product claims.
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.
