Amazon Elastic Compute Cloud (EC2) forms a central part of Amazon.com's cloud-computing platform, Amazon Web Services (AWS), by allowing users to rent virtual computers on which to run their own computer applications. EC2 encourages scalable deployment of applications by providing a web service through which a user can boot an Amazon Machine Image to configure a virtual machine, which Amazon calls an "instance", containing any software desired. A user can create, launch, and terminate server-instances as needed, paying by the hour for active servers - hence the term "elastic". EC2 provides users with control over the geographical location of instances that allows for latency optimization and high levels of redundancy.〔 〕 In November 2010 Amazon switched its own retail website to using EC2 and AWS.〔 〕 ==History== Amazon announced a limited public beta test of EC2 on August 25, 2006, offering access on a first-come, first-served basis. Amazon added two new instance types (Large and Extra-Large) on October 16, 2007.〔(【引用サイトリンク】title=Amazon EC2 Gets More Muscle )〕 On May 29, 2008, two more types were added, High-CPU Medium and High-CPU Extra Large. There are twelve types of instances available.〔(Amazon EC2 Instances ). Aws.amazon.com. Retrieved on 2013-08-09.〕 Amazon added three new features on March 27, 2008: static IP addresses, availability zones, and user selectable kernels. On August 20, 2008, Amazon added Elastic Block Store (EBS) This provides persistent storage, a feature that had been lacking since the service was introduced. Amazon EC2 went into full production when it dropped the beta label on October 23, 2008. On the same day, Amazon announced the following features: a service level agreement for EC2, Microsoft Windows in beta form on EC2, Microsoft SQL Server in beta form on EC2, plans for an AWS management console, and plans for load balancing, autoscaling, and cloud monitoring services.〔 These features were subsequently added on May 18, 2009. Amazon EC2 was developed mostly by a team in Cape Town, South Africa led by Chris Pinkham.〔(【引用サイトリンク】title=Amazon opens Cape software centre )〕〔(【引用サイトリンク】title=Amazon opens dev centre in Cape Town )〕〔(【引用サイトリンク】title=Amazon's Pinkham quits )〕〔(【引用サイトリンク】title=Amazon’s early efforts at cloud computing? Partly accidental )〕 Pinkham provided the initial architecture guidance for EC2 and then built the team and led the development of the project. Some other members of the early team included Christopher Brown, Quinton Hoole, Roland Paterson-Jones, Willem Van Biljon, Peter DeSantis, Marcin Kowalski, Benjamin Tobler, James Greenfield, Atle Jorgensen, Alan Powell, Eden Adogla, Liehann Loots, David Brown, Anton Eicher, Christopher de Kadt, Greg Kempe, Riel Smit, Jeremy Thurgood and Andries Dippenaar. 抄文引用元・出典: フリー百科事典『 ウィキペディア(Wikipedia)』 ■ウィキペディアで「Amazon Elastic Compute Cloud」の詳細全文を読む スポンサード リンク
