Introduction: This scalability strategy is brought to you by Erik Osterman: My recommendations for anyone dealing with explosive growth on a limited budget with lots of cachable content (e.g. content capable of returning valid expiration headers) is employ a reverse proxy as mentioned in this article. In the last week, we had a site get AP'd, triggering 100K unique visitors to a single IIS server in under 5 hours. It took out the IIS server. Placing a single squid infront of the server handled the entire onslaught with a max server load of 0.10 on a modest Intel IV 3Ghz. It's trivial to implement for anyone interested...

Introduction: Like many other media content providers, libraries and museums are increasingly moving their content onto the Web. While the move itself is no easy process (with digitization, web development, and training costs), being able to successfully deliver content to a wide audience is an ongoing concern, particularly for large libraries. Much of the concern is financial, as most libraries do not have the internal budget or outside investors that for-profit businesses enjoy. Even large university libraries will face serious budget constraints that even other university departments, such as science and technology would not face. Creating a scalable infrastructure and also distributing a large digital collection that can handle multiple requests, requires planning that many librarians have not even imagined. They must stop thinking in terms of "one-item-per-customer" and start thinking in terms of numerous users accessing the same information simultaneously. Content Delivery Network

Introduction: My company is developing a centralized web platform to service our clients. We currently use about 3Mb/s on our uplink at our ISP serving web pages for about 100 clients. We'd like to offer them statistics that mean something to their businesses and have been contemplating writing our own statistics code to handle the task. All statistics would be gathered at the page view level and we're implementing a HttpModule in ASP.Net 2.0 to handle the gather of the data. That said, I'm curious to hear comments on writing this data (~500 bytes of log data/page request). We need to write this data somewhere and then build a process to aggregate the data into a warehouse application used in our reporting system. Google Analytics is out of the question because we do not want our hosting infrastructure dependant upon a remote server. Web Trends et al. are too expensive for our clients. I'm thinking of a couple of options. 1) Writing log data directly to a SQL Server 2000 db and havin

Introduction: Update: Nice explanation in The importance of bandwidth versus latency of how long latencies cause cascading delays in resource loading. Doloto tries to optimize how resources are loaded. Twenty new rules have been added to the original 14 rules for sizzling web performance. Part of scalability is worrying about performance too. The front-end is where 80-90% of end-user response time is spent and following these best practices improved the performance of Yahoo! properties by 25-50%. The rules are divided into server, content, cookie, JavaScript, CSS, images, and mobile categories. The new rules are: Flush the buffer early [server] Use GET for AJAX requests [server] Post-load components [content] Preload components [content] Reduce the number of DOM elements [content] Split components across domains [content] Minimize the number of iframes [content] No 404s [content] Reduce cookie size [cookie] Use cookie-free domains for components [coo
4 0.74001598 319 high scalability-2008-05-14-Scaling an image upload service
Introduction: Hi, First of all I want to to say that this is an extremely interesting and informative website. i have enjoyed reading the various posts on how the big sites scale to meet the needs of their customers. The service we are developing is a webcam service. The client application sends images to the server via HTTP POST and they are saved in folder specified by the users id. When a new image is sent to the server it will overwrite the current image. Users can then view the images via our web server. Ideally we want the images to upload as quickly as possible and allow users to view them as quickly as possible. Would I be correct to assume that when the number of uploading clients exceeds the capability of the server the only way to scale is to add more hardware. Also I assume that to use HTTP accelerator caches will not speed up viewing the images as the new images will invalidate the cache. I appreciate any input on the subject.

Introduction: MySQL™ database, an open source database, delivers high performance and reliability while keeping costs low by eliminating licensing fees. The Solaris™ Cluster product is an integrated hardware and software environment that can be used to create highly-available data services. This article explains how to deploy the MySQL database in a Solaris Cluster environment. The article addresses the following topics: * "Advantages of Deploying MySQL Database with Solaris Cluster" on page 1 discusses the benefits provided by a Solaris Cluster deployment of the MySQL database. * "Overview of Solaris Cluster" on page 2 provides a high-level description of the hardware and software components of the Solaris Cluster. * "Installation and Configuration" on page 8 explains the procedure for deploying the MySQL database on a Solaris Cluster. This article assumes that readers have a basic understanding of Solaris Cluster and MySQL database installation and administration.
Introduction: Authors: Kevin Lim Parthasarathy Ranganathan Jichuan Chang Chandrakant Patel Trevor Mudge Steven Reinhardt This International Symposium on Computer Architecture paper seeks to understand and design next-generation servers for emerging "warehouse-computing" environments. We make two key contributions. First, we put together a detailed evaluation infrastructure including a new benchmark suite for warehouse-computing workloads, and detailed performance, cost, and power models, to quantitatively characterize bottlenecks. Second, we study a new solution that incorporates volume non-server-class components in novel packaging solutions, with memory sharing and flash-based disk caching . Our results show that this approach has promise, with a 2X improvement on average in performance-per-dollar for our benchmark suite.
4 0.457589 1018 high scalability-2011-04-07-Paper: A Co-Relational Model of Data for Large Shared Data Banks
Introduction: Let's play a quick game of truth or sacrilage: are SQL and NoSQL are really just two sides of the same coin? That's what Erik Meijer and Gavin Bierman would have us believe in their "we can all get along and make a lot of money" article in the Communications of the ACM, A Co-Relational Model of Data for Large Shared Data Banks . You don't believe it? It's math, so it must be true :-) Some key points: In this article we present a mathematical data model for the most common noSQL databases—namely, key/value relationships—and demonstrate that this data model is the mathematical dual of SQL's relational data model of foreign-/primary-key relationships ...we believe that our categorical data-model formalization and monadic query language will allow the same economic growth to occur for coSQL key-value stores. ...In contrast to common belief, the question of big versus small data is orthogonal to the question of SQL versus coSQL. While the coSQL model naturally supports extreme sh

Introduction: Looks interesting... Abstract: Today’s data centers may contain tens of thousands of computers with significant aggregate bandwidth requirements. The network architecture typically consists of a tree of routing and switching elements with progressively more specialized and expensive equipment moving up the network hierarchy. Unfortunately, even when deploying the highest-end IP switches/routers, resulting topologies may only support 50% of the aggregate bandwidth available at the edge of the network, while still incurring tremendous cost. Nonuniform bandwidth among data center nodes complicates application design and limits overall system performance. In this paper, we show how to leverage largely commodity Ethernet switches to support the full aggregate bandwidth of clusters consisting of tens of thousands of elements. Similar to how clusters of commodity computers have largely replaced more specialized SMPs and MPPs, we argue that appropriately architected and interconnected commodi
