PUBLIC MARKS with tag cdn

Are you tired of clicking on some link from a web portal, only to find that the website is temporarily off-line because thousands or millions of other users are also trying to access it? Does your network have a really low-bandwidth connection, such that everyone, even accessing the same web pages, suffers from slow downloads? Have you ever run a website, only to find that suddenly you get hit with a spike of thousands of requests, overloading your server and possibly causing high monthly bills? If so, CoralCDN might be your free solution for these problems!

Introduction aux CDN...

This post isn't meant to be an end all to Drupal and CDNs, but rather just some insight into the way I have tackled this issue for the time being. There are a number of options to choose from and a lot of different ways to go about it. You could get a new server locally and load balance your stuff, you could get a new server locally and use it as a static file server, you could team up with a big time CDN like Akamai or Limelight and go that route, or you could go the less expensive CDN route with something like Amazon S3.

On me pose souvent la question du coût des solutions de CDN Akamai pour gérer la disponibilité d’un site. Et en général le problème majeur avec cet acteur vient des frais de fonctionnement et de mise en service. En effet au delà de l’engagement contractuel sur la durée la mise en place d’une solution Akamai est relativement coûteuse pour des “petits” acteurs. Cette annonce d’Amazon est donc une très bonne nouvelle pour le segment des sites de taille moyenne, trop petits pour négocier avec Akamai et gérant déjà un trafic suffisamment important pour être obligé de mettre en place des solutions de cache distribués, des CDN.

"4月1日の同サイトへのアクセス数は最終的に150万ページビューに達した。これは通常の約15倍、既存のサーバの構成では想定していない規模だという。その後、サーバのメモリ増設、スペック強化、価格投稿機能に直接影響のない機能の休止、投稿機能の別サーバ化、コンテンツ表示部分の効率化といった対策を施し、事態に対処している。だが4月4日午後の2時現在もアクセスが集中しており、「メンテナンス中」の状態だ。深夜は落ち着いているが、日中はWEBサーバ、DBサーバに処理能力以上の負荷が掛かっている状況という。"
