Introduction: Hi, Can someone teach me how you implement network switch fail over since we are paranoid for single point of failure. For example, you have: a dozen web servers -> switch -> DB cluster that switch is a SPOF. How does one implement dual switch in a fail over fashion?

Introduction: With cloud SLAs generally being worth what you don't pay for them, what can you do to protect yourself? Sean Hull in AirBNB didn’t have to fail has some solid advice on how to deal with outages: Use Redundancy . Make database and webserver tiers redundant using multi-az or alternately read-replicas. Have a browsing only mode . Give users a read-only version of your site. Users may not even notice failures as they will only see problems when they need to perform a write operation. Web Applications need Feature Flags . Build in the ability to turn off and on major parts of your site and flip the switch when problems arise. Consider Netflix’s Simian . By randomly causing outages in your application you can continually test your failover and redundancy infrastructure. Use multiple clouds . Use Redundant Arrays of Inexpensive Clouds as a way of surviving outages in any one particular cloud. None of these are easy and it's worth considering that your application may

Introduction: Snabb Switch - a toolkit for solving novel problems in networking. If you are building a new packet-processing network appliance then you can use Snabb Switch to get the job done more quickly. Here's a great impassioned overview from erichocean : Or, you could just avoid the OS altogether: https://github.com/SnabbCo/snabbswitch Our current engineering target is 1 million writes/sec and > 10 million reads/sec on top of an architecture similar to that, on a single box, to our fully transactional, MVCC database (write do not block reads, and vice versa) that runs in the same process (a la SQLite), which we've also merged with our application code and our caching tier, so we're down to—literally—a single process for what would have been at least three separate tiers in a traditional setup. The result is that we had to move to measuring request latency in microseconds exclusively. The architecture (without additional application-specific processing) supports a wire-to-wire mes

Introduction: By Bhavin Turakhia CEO, Directi. Covers: * Why scalability is important. Viral marketing can result in instant success. With RSS/Ajax/SOA number of requests grow exponentially with user base. Goal is to build a web 2.0 app that can server millions of users with zero downtime. * Introduction to the variables. Scalability, performance, responsiveness, availability, downtime impact, cost, maintenance effort. * Introduction to the factors. Platform selection, hardware, application design, database architecture, deployment architecture, storage architecture, abuse prevention, monitoring mechanisms, etc. * Building our own scalable architecture in incremental steps: vertical scaling, vertical partitioning, horizontal scaling, horizontal partitioning, etc. First buy bigger. Then deploy each service on a separate node. Then increase the number of nudes and load balance. Deal with session management. Remove single points of failure. Use a shared nothing cluster.

Introduction: Summary In this presentation, a three steps approach for turning your existing stateful tier-based/Spring-application into a dynamically scalable services application using OpenSpaces is demonstrated. The existing programming model is kept the same while focusing on abstracting and replacing the underlying implementations of the middleware stack in a way that will fit the scale-out model. Bio Nati Shalom is the CTO and Founder of GigaSpaces and responsible for the technology roadmap. He has 10 years of experience with distributed technology and architecture namely CORBA, Jini, J2EE, Grid and SOA. Nati is the Head of the Israeli Grid consortium and an evangelist of Space Based Architecture and Data Grid patterns. Blog: Gigaspaces Blog Read the rest of the article here on InfoQ .

Introduction: Hi, I want to implement a search engine with lucene. To be scalable, I would like to execute search jobs asynchronously (with a job queuing system). But i don't know if it is a good design... Why ? Search results can be large ! (eg: 100+ pages with 25 documents per page) With asynchronous sytem, I need to store results for each search job. I can set a short expiration time (~5 min) for each search result, but it's still large. What do you think about it ? Which design would you use for that ? Thanks Mat
