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

7 on the web application server, CDNs host the static content on multiple redundant servers, spread across numerous geographic locations. [sent-9, score-0.535]
8 When a user accesses a particular collection piece, the CDN will locate the server closest to the user, with the fewest hops to get the the user, and deliver the content. [sent-10, score-0.52]
9 To reduce costs, libraries and museums can consider using pay-per-view CDN services, such as Amazon Web Services, to handle content delivery. [sent-13, score-0.743]
10 Metadata Server A large part of the data distributed through a digital library is metadata. [sent-14, score-0.467]
11 Whereas a website like Flickr may have optional tags, a digital library's metadata is usually larger and more in-depth. [sent-15, score-0.375]
12 As a site grows and visitors increase, managing multiple queries can create bottlenecks and even interruptions in service. [sent-21, score-0.389]
13 On many small library websites, the user enters a search query and the search engine scours the database to find the keywords, subjects, authors, and/or titles that match. [sent-22, score-0.744]
14 Peer-to-peer routing is more complex but can be effective when there are large numbers of users entering identical or similar queries. [sent-27, score-0.329]
15 In this model, the server will have redundant nodes that route multiple users, reducing the load on single nodes and making individual user response time shorter. [sent-28, score-0.688]
16 Caching With a multitude of static content and redundant queries, caching simply makes sense. [sent-29, score-0.495]
17 If 5,000 people per day are looking at the same picture of a Persian sculpture, caching the image and metadata will reduce response time. [sent-30, score-0.392]
18 Furthermore, if 3,000 of those 5,000 users all used the exact same search terms to find the data, the server should not have to perform that search again, rather it can access the cached search and automatically display the associated results. [sent-31, score-0.983]
19 You should try to compress as many bytes as possible, even if the files are tiny, but rather deliver as few packets as possible. [sent-40, score-0.437]
20 Whether you are a non-profit traditional library, an independent movie database, a photo sharing site, or a large content wiki, your digital library will need to be prepared for voluminous content distribution and a multitude of user requests. [sent-41, score-1.323]

Introduction: We build web applications…and there are plenty of them around. Now, if we hit the jackpot and our application becomes very popular, traffic goes up, and our servers are brought down by the hordes of people coming to our website. What do we do in that situation? Of course, I am not talking here about the kind of traffic Digg, Yahoo Buzz or other social media sites can bring to a website, which is temporary overnight traffic, or a website which uses cloud computing like Amazon EC2 service, MediaTemple Grid Service or Mosso Hosting Cloud service. I am talking about traffic that consistently increases over time as the service achieves success. Google.com, Yahoo.com, Myspace.com, Facebook.com, Plentyoffish.com, Linkedin.com, Youtube.com and others are examples of services which have constant high traffic. Knowing that users want speed from their applications, these services will always use a Content Delivery Network (CDN) to deliver that speed. What is a Content Delivery Ne

Introduction: Update 10: The Value of CDNs by Mike Axelrod of Google. Google implements a distributed content cache from within large ISPs . This allows them to serve content from the edge of the network and save bandwidth on the ISPs backbone. Update 9: Just Jump: Start using Clouds and CDNs . Bob Buffone gives a really nice and practical tutorial of how to use CloudFront as your CDN. Update 8: Akamai’s Services Become Affordable for Anyone! Blazing Web Site Performance by Distribution Cloud . Distribution Cloud starts at $150 per month for access to the best content distribution network in the world and the leader of Content Distribution Networks. Update 7: Where Amazon’s Data Centers Are Located , Expanding the Cloud: Amazon CloudFront . Why Amazon's CDN Offering Is No Threat To Akamai, Limelight or CDN Pricing . Amazon has launched their CDN with "“low latency, high data transfer speeds, and no commitments.” The perfect relationship for many. The m

Introduction: Update 2: YouTube Reaches One Billion Views Per Day . That’s at least 11,574 views per second, 694,444 views per minute, and 41,666,667 views per hour. Update: YouTube: The Platform . YouTube adds a new rich set of APIs in order to become your video platform leader--all for free. Upload, edit, watch, search, and comment on video from your own site without visiting YouTube. Compose your site internally from APIs because you'll need to expose them later anyway. YouTube grew incredibly fast, to over 100 million video views per day, with only a handful of people responsible for scaling the site. How did they manage to deliver all that video to all those users? And how have they evolved since being acquired by Google?

5 0.1555091 1102 high scalability-2011-08-22-Strategy: Run a Scalable, Available, and Cheap Static Site on S3 or GitHub
Introduction: One of the best projects I've ever worked on was creating a large scale web site publishing system that was almost entirely static. A large team of very talented creatives made the art work, writers penned the content, and designers generated templates. All assets were controlled in a database. Then all that was extracted, after applying many different filters, to a static site that was uploaded via ftp to dozens of web servers. It worked great. Reliable, fast, cheap, and simple. Updates were a bit of a pain as it required pushing a lot of files to a lot of servers, and that took time, but otherwise a solid system. Alas, this elegant system was replaced with a new fangled dynamic database based system. Content was pulled from a database using a dynamic language generated front-end. With a recent series of posts from Amazon's Werner Vogels, chronicling his experience of transforming his All Things Distributed blog into a static site using S3's ability to serve web pages, I get th

Introduction: If you have a lot of static content to store and you aren't looking forward to setting up and maintaining your own giganto SAN, maybe you can push off a lot of the hard lifting to a CDN? Jesse Robbins at O'Reilly Radar posts that you have a lot more options now because the number of Content Distribution Networks have doubled since last year . In fact, Dan Rayburn says there are now 28 CDN providers in the market. Hopefully you can find reasonable pricing at one of them. Other than easing your burden, why might a CDN work for you? Because it makes your site faster and customers like that. How can a CDN so dramatically improve your site's performance? Steve Saunders, author of High Performance Web Sites: Essential Knowledge for Front-End Engineers , has using a CDN has one of his "Thirteen Simple Rules for Speeding Up Your Web Site." About CDNs Steve says: Remember that 80-90% of the end-user response time is spent downloading all the components in

Not exactly... Yottaa reports an amazing 13 advertiser websites crashed during the Super Bowl. Coke was interactively au currant, asking viewers to vote for the ending of a commercial, but load times went to 62 seconds. SodaStream, Calvin Klein, Axe, Got Milk? The Walking Dead, many movie sites, and many car sites, all were flagged with delay of fame penalties. Lots of time, money, and creative energy is spent lovingly perfecting every detail of these commercials. It won't be a surprise to any programmer that this can't usually be said of the follow through on the backend. So what can you do?
