Experience
Ferrari
http://www.ferrari.com/我们选择了AWS,并重新设计了应用程序,以利用AWS的所有组件,如计算实例, dedicated databases, load balancers, Memcached servers, CDN, and PHP optimizations. Load tests demonstrated good results, with >80% savings on starting costs. Nowadays, 基础设施由多个Amazon EC2实例和多个RDS实例组成,这些实例位于多区域+多读副本中. We increased the total number of instances to 200. The infrastructure also takes advantage of Amazon S3 and CloudFront.
Qurami (now ufirst)
http://apps.apple.com/us/app/ufirst/id470837979服务器架构基于Silex,并通过XMPP协议与远程Java代理进行通信. The server provides an API to interact with mobile devices. 我们在AWS堆栈上实现了一个健壮的解决方案来处理大量的远程代理(可能有数千个), ensuring scalability, stability, and privacy. Also, 我们解决了关键的管理点,以支持Qurami在意大利不同地点的分布式运营.
Ringpay
Punctis
I designed their infrastructure, handling development, testing, and production environments with automated migrations and scalability. It was all implemented on AWS using EC2 and RDS. 因为主要的负载不是网站而是REST API,所以我们决定不使用CloudFront.
Beatipick
http://www.beatpick.com/我用开源产品取代了亚马逊的所有专有技术(由其他团队成员提供和配置), ensuring no disruption happened in the platform. I also migrated the whole application and media library to AWS using EC2, RDS, S3, and CloudFront (including stress test and automation for fail recovery).
