Scalability
This post I provided a summary of recent discussions outlining the main challenges that developers face today when deploying their existing JEE application to the cloud such as complexity, database integration, security, standard JEE support etc. In this post i also provided summary of how we managed to handle those

For those interested in building scalable systems, today I will speak about the Facebook Char architecture. Starting keynote: ''When your feature’s userbase will go from 0 to 70 million practically overnight, scalability has to be baked in from the start.'' Eugene Lutuchy, lead engineer on
General Discussion
Hibernate and iBATIS and other similar tools have documentation with recommendations for avoiding the "N+1 select" problem. The problem being that if you wanted to retrieve a set of widgets from a table, one query would be used to to retrieve all the ids of the matching

Learned lessons from the largest player (Flickr, YouTube, Google, etc) I would like to write today about some learned lessons from the biggest player in the high Scalable Web application. I will divide the lessons into 4 points: * Start slow, and small, and measuring the right thing. * Vertical Scalability vs.

Evan Weaver from Twitter presented a talk on Twitter software upgrades, titled Improving running components as part of the Systems that never stop track at QCon London 2009 conference last Friday. The talk focused on several upgrades performed since last May, while Twitter was experiencing serious performance problems.
Scalability
Over the last several decades computer architects have been phenomenally successful turning the transistor bounty provided by Moore's Law into chips with ever increasing single-threaded performance. During many of these successful years, however, many researchers paid scant attention to multiprocessor work. Now as vendors turn to multicore chips,

Many web applications, including eBanking, Trading, eCommerce and Online Gaming, face large, fluctuating loads. In this post will describe how to achieve Right Sizing using virtualization and cloud computing. Will use a standard JEE web application to demonstrate how auto-scaling works on AWS Cloud without changing your application code.
Scalability
I follow a certain philosophy when developing system architectures. I assume that very few systems will ever exist in a consistent form for more than a short period of time. What constitutes a “short period of time” differs depending on the specifics of each system, but in an effort to

Before We started with a small site, a mess of open source, and a small team that didn't know much about scaling. After We ended with a large site, a medium sized team, and an architecture that has scaled. We never stopped. We used a roadmap and a
Database
The most important aspect of a scalable web architecture is data partitioning. Most components in a modern data center are completely stateless, meaning they just do batches of work that is handed to them, but don't store any data long-term. This is true of most web application servers,
