Scaling Australia's Most Popular Online News Sites with Ehcache

Posted by Ari Zilka and Matthias Matook  on  Dec 06, 2010 4

Matthias Matook and Ari Zilka share the real-world experience of implementing Enterprise Ehcache at Australia's most visited online news sites. The talk will focus on the challenges and technical solutions to deal with massive page hits, high concurrency and how to achieve linear scalability without additional hardware.

Scaling Your Cache & Caching at Scale

Posted by Alex Miller  on  Jun 07, 2010

Alex Miller explains shortly why caching is useful, followed by examples of typical difficulties encountered when setting up a cache, like large datasets, data eviction, stale data, replication, loading, duplication. Miller also discusses available choices for designing a distributed caching architecture, and ways to test a cache for performance.

Scale at Facebook

Posted by Aditya Agarwal  on  May 28, 2010 3

Beside presenting the overall Facebook architecture and scaling solutions used, Aditya Agarwal talks about the iterative process of constantly improving the site, making sure to avoid over-engineering and adapting along the way by dropping solutions that worked in the past but are no longer useful. The last part of the session was dedicated to answering questions from the audience.

Horizontal Scalability via Transient, Shardable, and Share-Nothing Resources

Posted by Adam Wiggins  on  Apr 20, 2010 1

Adam Wiggins believes that now is the time of horizontal scalability achieved by using resources that are transient, shardable and share nothing with other resources. He gives as example several applications and a language: memcached, CouchDB, Hadoop, Redis, Varnish, RabbitMQ, Erlang, detailing how each one applies those principles.

Evolving the Key/Value Programming Model to a Higher Level

Posted by Billy Newport  on  Jan 19, 2010 6

In this presentation from QCon San Francisco 2009, Billy Newport discusses the ways that developers interact with key/value (KV) stores such as memcached and WebSphere eXtreme Scale, entity vs column-oriented approaches, synchronous and asynchronous operations, large data sets, using a DBMS as a column store, collocating closures and data, and features that could be added to increase scalability.

A Crash Course in Modern Hardware

Posted by Cliff Click  on  Jan 12, 2010 17

In this presentation from the JVM Languages Summit 2009, Cliff Click discusses the Von Neumann architecture, CISC vs RISC, the rise of multicore, Instruction-Level Parallelism (ILP), pipelining, out-of-order dispatch, static vs dynamic ILP, performance impact of cache misses, memory performance, memory vs CPU caching, examples of memory/CPU cache interaction, and tips for improving performance.

Data Grid Design Patterns

Posted by Brian Oliver  on  Nov 04, 2009

Brian Oliver explains a number of data grid design patters: Command, Functor, Store and Forward Messaging, and Push Replication. He also mentions some traditional patterns used so far and Coherence Incubator, a repository for design patterns reference implementations.

An Introduction to Data Grids

Posted by Cameron Purdy  on  Oct 10, 2009 1

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.

Transforming the Reconciliation Process

Posted by Brian Oliver  on  Sep 23, 2009

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.

Multicore Programming in Erlang

Posted by Ulf Wiger  on  Jul 16, 2009

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.

RESTful Enterprise Development

Posted by Ian Robinson  on  Apr 29, 2009 2

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 Status Report

Posted by Mark Nottingham  on  Apr 19, 2009 3

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.
