- Lessons Learned, Survival-Stories etc. von Firmen mit Amazon-Infrastruktur Before 5 AM Eastern on April 21st, 2011, an outage started at EC2's northern Virginia datacenter that brought down hundreds of web 2.0 and social media websites including Foursquare, Springpad, Reddit, Quora, BigDoor and Hootsuite. Specifically, attempts to use Amazon's elastic-disk and database services hung, failed, or were slow. Service was restored to some parts of the datacenter (three of four "availability zones" in Amazon's terms) by late afternoon Eastern time that day
Cloud Tools is a set of tools for deploying, managing and testing Java EE applications on Amazon's Elastic Computing Cloud (EC2) and VMware environments. There are three main parts to Cloud Tools:
* EC2Deploy - the core framework. This framework manages virtual instances (e.g. EC2), configures MySQL, Tomcat, Terracotta and Apache and deploys the application. See this blog entry for an overview.
* Maven and Grails plugins that use EC2Deploy to deploy an application
* Amazon Machine Images (AMIs) that are configured to run Tomcat and work with EC2Deploy. See list of installed software.
Amazon Elastic Compute Cloud (Amazon EC2) is a web service that provides resizable compute capacity in the cloud. It is designed to make web-scale computing easier for developers.
Amazon EC2’s simple web service interface allows you to obtain and configure capacity with minimal friction. It provides you with complete control of your computing resources and lets you run on Amazon’s proven computing environment. Amazon EC2 reduces the time required to obtain and boot new server instances to minutes, allowing you to quickly scale capacity, both up and down, as your computing requirements change. Amazon EC2 changes the economics of computing by allowing you to pay only for capacity that you actually use. Amazon EC2 provides developers the tools to build failure resilient applications and isolate themselves from common failure scenarios.
