Introduction: Hi, I am using drupal for my clients website, and was thinking is it possible to host all ( about 500) of them on the same server(maybe VPS or dedicated). Here is the situation..... Each clients website has a database with about 50 tables each, all the databases are small in size about 2-5 MB .... and the websites are low traffic websites with say.. 50 hits/day on avg.... that means about 2000 queries/db/day ..... (avg 40 queries per hit).... Wanted to know if it is possible to have so many databases about 500 on the same server? what are the things that i should look into if i should make this happen?
3 0.074692398 1615 high scalability-2014-03-19-Strategy: Three Techniques to Survive Traffic Surges by Quickly Scaling Your Site
Introduction: Matthew Might , as a first responder to a surprise traffic surge on his inexpensive linode hosted blog, took emergency steps that you might find useful in a similar situation: Find the bottleneck. Reloading the page in firebug showed the first page took 24 seconds to load and after that everything else loaded quickly. In retrospect this burst meant the site was thread limited as the CPU was idle. Cut image sizes in half with a shell script using ImageMagick's convert. Load time is now 12 seconds. Turn dynamic content into static content using a static index.html file copied using the browser's "view source" feature. Load time is now 6 seconds. Added threads to the Apache configuration file. Load time is now 2 seconds. Crises averted. Because of this quick thinking and quick action the patient survived to serve pages another day. And in fine post-mortem tradition some of the future changes are: Run a cron job to trigger an earlier alert . Email when requ

Introduction: Launched in 2001 by Microsoft, since then this platform is widely popular among organizations to increase the efficiency of their business and productive volume. As we all know the importance of communication mode in every organization and by keeping in the mind this fact, Microsoft SharePoint communicates over all barriers and spread the required information within a company. Microsoft SharePoint is an ideal solution for companies who have multiple offices and staff members who are on the move. Using SharePoint, documents and other materials can be easily shared with both colleagues and managers. Other features include advanced document management, which allows users to virtually check out a document, modify it or just read it, then check in the document again. This allows managers/company owners to see exactly when their staff members are working and just what they are doing. When combined with a highly customizable workflow management system and group calendars, SharePoint can imp
Introduction: Snooze is an open-source, scalable, autonomic, and energy-efficient virtual machine (VM) management framework for private clouds. Similarly to other VM management frameworks such as Nimbus, OpenNebula, Eucalyptus, and OpenStack it allows to build compute infrastructures from virtualized resources. Particularly, once installed and configured users can submit and control the life-cycle of a large number of VMs. However, contrary to existing frameworks for scalability and fault tolerance, Snooze employs a self-organizing and healing (based on Apache ZooKeeper) hierarchical architecture. Moreover, it performs distributed VM management and is designed to be energy efficient. Therefore, it implements features to monitor and estimate VM resource (CPU, memory, network Rx, network Tx) demands, detect and resolve overload/underload situations, perform dynamic VM consolidation through live migration, and finally power management to save energy. Last but not least, it integrates a g

2 0.51546735 759 high scalability-2010-01-11-Strategy: Don't Use Polling for Real-time Feeds
Introduction: Ivan Zuzak wrote a fascinating article on Real-time feed processing and filtering using Google App Engine to build Feed-buster , a service that inserts MediaRSS tags into feeds that don't have them . He talks about using polling and PubSubHubBub (real-time) to process FriendFeed feeds. Ivan is trying to devise a separate filtering service where: filtering services should be applied as close to the publisher as possible so notifications that nobody wants don’t waste network resource. processing services should be applied as close to the subscriber so that the original update may be transported through the network as a single notification for as long as possible. Besides being a generally interesting article, Ivan makes an insightful observation on the nature of using polling services in combination with metered Infrastructure/Platform services: Polling is bad because AppEngine applications have a fixed free daily quota for consumed resources, when the numbe

Introduction: Update 6 : nginx_http_push_module . Turn nginx into a long-polling message queuing HTTP push server. Update 5 : In Load Balancer Update Barry describes how WordPress.com moved from Pound to Nginx and are now "regularly serving about 8-9k requests/second and about 1.2Gbit/sec through a few Nginx instances and have plenty of room to grow!". Update 4 : Nginx better than Pound for load balancing. Pound spikes at 80% CPU, Nginx uses 3% and is easier to understand and better documented. Update 3 : igvita.com combines two cool tools together for better performance in Nginx and Memcached, a 400% boost! . Update 2 : Software Project on Installing Nginx Web Server w/ PHP and SSL . Breaking away from mother Apache can be a scary proposition and this kind of getting started article really helps easy the separation. Update: Slicehost has some nice tutorials on setting up Nginx .

5 0.43024489 58 high scalability-2007-08-04-Product: Cacti
Introduction: Cacti is a network statistics graphing tool designed as a frontend to RRDtool's data storage and graphing functionality. It is intended to be intuitive and easy to use, as well as robust and scalable. It is generally used to graph time-series data like CPU load and bandwidth use. The frontend is written in PHP; it can handle multiple users, each with their own graph sets, so it is sometimes used by web hosting providers (especially dedicated server, virtual private server, and colocation providers) to display bandwidth statistics for their customers. It can be used to configure the data collection itself, allowing certain setups to be monitored without any manual configuration of RRDtool.

2 0.3799361 278 high scalability-2008-03-16-Product: GlusterFS
Introduction: Adapted from their website: GlusterFS is a clustered file-system capable of scaling to several peta-bytes. It aggregates various storage bricks over Infiniband RDMA or TCP/IP interconnect into one large parallel network file system. Storage bricks can be made of any commodity hardware such as x86-64 server with SATA-II RAID and Infiniband HBA). Cluster file systems are still not mature for enterprise market. They are too complex to deploy and maintain though they are extremely scalable and cheap. Can be entirely built out of commodity OS and hardware. GlusterFS hopes to solves this problem. GlusterFS achieved 35 GBps read throughput . The GlusterFS Aggregated I/O Benchmark was performed on 64 bricks clustered storage system over 10 Gbps Infiniband interconnect. A cluster of 220 clients pounded the storage system with multiple dd (disk-dump) instances, each reading / writing a 1 GB file with 1MB block size. GlusterFS was configured with unify translator and round-robin scheduler

Introduction: From a reader: > Was reading through your very interesting/useful site. >Most of the architectures are non j2ee-Does that mean that >there aren't enough websites that are scalable(with youtube > like userbase) built with j2ee tech-would like to know if there > are any and their architecture as >well. eBay uses Java, but in a very pragmatic way. They use servlets, an application server, the JDK, and they do the rest themselves. They skip JSP, entity beans, and JMS. When you need to scale putting all your eggs in one basket is a risky strategy. Why use JSP when you can do better? When use entity beans when you can do better? Use servlets because they are a very effective way of handling http requests. Use Java because it is fast, runs everywhere, and has a boat load of libraries you can use to build your build your custom system. Probably the major reason J2EE is absentee is simply LAMP. LAMP is just so incredibly functional for most 2-tier shared nothing site

Introduction: Cal Henderson writes at thinkvitamin.com : "With our so-called "Web 2.0' applications and their rich content and interaction, we expect our applications to increasingly make use of CSS and JavaScript. To make sure these applications are nice and snappy to use, we need to optimize the size and nature of content required to render the page, making sure we’re delivering the optimum experience. In practice, this means a combination of making our content as small and fast to download as possible, while avoiding unnecessarily refetching unmodified resources." A lot of good comments too.
