''The Rackspace Cloud''' is a [[web application]] [[web hosting|hosting]]/[[cloud platform]] provider ("''Cloud Sites''") that bills on a [[utility computing]] basis. It has since branched out into [[cloud storage]] ("''Cloud Files''") and [[cloud infrastructure]] ("''Cloud Servers''") and is "already a real leader in the cloud" according to analyst Signal Hill.

It is notable because it has won awards, including Performancing's editors choice for ''Best Blog WebHost of 2007'' and garnered special attention for the unprecedented appointment of a ''Chief Uptime Officer''. It was also one of the first commercial [[cloud computing]] services.

On August 25, 2009 Rackspace Cloud rolled out Cloud Tools, "a repository of partner tools, applications and services for cloud computing".

== History ==
[[Image:MossoLogo.png|right|thumb|The original Mosso logo]]
'''The Rackspace Cloud''' was originally launched as '''Mosso LLC''' on March 4, 2006, a wholly owned subsidiary startup billed as a [[utility computing]] offering. As it pre-dated mainstream adoption of [[cloud computing]] it was "retooled" and relaunched on February 19, 2008, adopting the tagline "Mosso: The Hosting Cloud". The "Mosso" branding (including the '''mosso.com''' domain) was then dropped on June 17, 2009 in favour of "The Rackspace Cloud" branding (including the '''rackspacecloud.com''' domain). Since then, customer contracts have been executed with Rackspace US, Inc. d/b/a The Rackspace Cloud rather than with the Mosso LLC subsidiary.

Other companies (such as [[EMC Corporation|EMC]] with its "Decho" subsidiary) also use alternative branding for their [[cloud computing]] offerings.

== Services ==
=== Cloud Files ===
'''Cloud files''' is a [[cloud storage]] service that provides "unlimited online storage and [[Content delivery network|CDN]]" for media (examples given include backups, video files, user content) on a [[utility computing]] basis (at USD 0.15/GB/month). It was originally launched as ''Mosso CloudFS'' on May 5, 2008 and is similar to [[Amazon Simple Storage Service]]. Unlimited files of up to 5 GB can be uploaded, managed via the online control panel or [[REST]]ful API and optionally served out via [[Akamai Technologies]]' [[Content Delivery Network]].

; API
In addition to the online control panel the service can be accessed over a [[REST]]ful API with [[open source]] client code available in [[C Sharp (programming language)|C#]]/[[.NET Framework|.NET]], [[Python (programming language)|Python]], [[PHP]], [[Java (programming language)|Java]] and [[Ruby (programming language)|Ruby]]. Rackspace-owned [[Jungle Disk]] allows Cloud Files to be mounted as a local drive within supported [[operating system]]s ([[Linux]], [[Mac OS X]] and [[Microsoft Windows|Windows]]).

; Security

Redundancy is provided by replication three full copies of data across multiple computers in multiple "zones" within the same data center, where "zones" are physically (though not geographically) separate and supplied separate power and Internet services. Uploaded files can be distributed via [[Akamai Technologies]] to "hundreds of endpoints across the world" which provides an additional layer
of data redundancy.

The control panel and API are protected by [[Secure Sockets Layer|SSL]] and the requests themselves are signed and can be safely delivered to untrusted clients. Deleted data is zeroed out immediately.

; Use cases

Use cases considered as "well suited" include backing up or archiving data, serving images and videos (which are streamed directly to the users' browsers), serving content over [[content delivery network]]s, storing secondary static web-accessible data, developing data storage applications, storing fluctuating and/or unpredictable amounts of data and reducing costs.

; Caveats
There is no native [[operating system]] support for the Cloud Files API so it is not yet possible to "map" or "mount" it as a virtual drive without third-party software like [http://www.jungledisk.com/ JungleDisk] that translates to a supported standard such as [[WebDAV]]. There are no concepts of "appending" or "locking" data within Cloud Files (which may affect some disk mirroring or backup solutions), nor support for permissions or transcoding. Data is organised into "containers" but it is not possible to create nested folders without a translation layer.

=== Cloud Servers ===
'''Cloud Servers''' is a [[cloud infrastructure]] service that allows users to deploy "one to hundreds of cloud servers instantly" and create of "advanced, high availability architectures", similar to the [[Amazon Elastic Compute Cloud]]. The "cloud servers" are actually [[virtual machine]]s running on the [[Xen]] hypervisor for Linux-based instances, and [[Citrix]] XenServer for Windows instances. Each quad core hardware node has between 16 and 32 GB of [[RAM]], allowing for allocations between 256 MB and 15.5 GB. Disk and CPU allocations scale up with memory, with disk sizes ranging from 10 GB to 620 GB. Various distributions of [[Linux]] are supported, including [[Arch Linux|Arch]], [[CentOS]], [[Debian]], [[Fedora (operating system)|Fedora]], [[Gentoo Linux|Gentoo]], [[Red Hat Linux|Red Hat]] and [[Ubuntu (operating system)|Ubuntu]].

The technology behind the service was purchased in Rackspace's October 22, 2008 acquisition of ''Slicehost'' and the servers were formerly known as "slices". These are "much cheaper and generally easier to use than a traditional dedicated server", though it is still necessary to maintain the [[operating system]] and [[solution stack]] which is not required for the ''Cloud Sites'' product.This is one of the main differentiators between the two services; where Cloud Servers includes full root access and thus allows for more customisation, the Cloud Sites product is less flexible but requires less maintenance.

On December 14, 2010, The Rackspace Cloud began offering a managed service level on the Cloud Servers product, which adds additional support for the operating system and common applications as well as patching and other routine services. This additional support level does come at an increased cost, however.

; API
The Cloud Servers API launched on July 14, 2009 under the [[Creative Commons]] Attribution 3.0 license allows clients to create, configure and control virtual servers. In addition to issuing basic management commands this "enables elastic scenarios" whereby servers are instantiated and destroyed in response to fluctuating load (one of the key characteristics of [[cloud computing]]). [[RightScale]] is among third-party providers to have announced support for this API.

=== Cloud Sites ===
Cloud Sites is a [[cloud platform]] offering, similar to traditional [[web hosting]] only built on [[scalability|horizontally scalable]] hardware infrastructure. A fixed monthly credit card payment gives users access to the service with an allocation of compute, storage and bandwidth resources. Should this allocation be exhausted then subsequent usage is billed on a [[utility computing]] basis. It allows an "unlimited" number of sites, databases and email accounts and includes reseller options such as client billing and support. Touted as "the fastest way to put sites on the cloud", it runs Windows or Linux applications across "hundreds of servers".

Cloud Sites supports the [[PHP 5]], [[Perl]], [[Python (programming language)|Python]], [[MySQL]], [[.NET Framework|.NET]] 2.0+, [[Active Server Pages|ASP]] and [[Microsoft SQL Server 2008]] application frameworks.

; Compute cycles
The service includes up to 10,000 "compute cycles" per month which "is roughly equivalent to running a server with a 2.8 GHz modern processor for the same period of time" (with additional cycles priced at USD 0.01). This non-standard unit of measurement primarily reflects CPU processing time but also includes [[I/O]] operations so pages with many database queries will consume more "compute cycles". It can however be difficult to compare services between providers without standard units of measurement.

; Caveats

Cloud Sites does not support [[Java (programming language)|Java]], [[Apache Tomcat|Tomcat]], [[ColdFusion]], [[Secure Shell|SSH]], [[Remote Desktop Protocol|RDP]], [[API]] access, [[Microsoft Exchange Server|Microsoft Exchange]] or custom server-side components at this time. It is also not possible to set up multiple top level domains to point to the same web root directory. The .NET environment dropped support for "full trust" in favour of "modified medium trust" despite having previously announced on their blog that they had been able to work directly with Microsoft to engineer a system that could accommodate Full Trust without compromising the security, scalability, and performance of other users.

== Server Locations ==

According to Chris A., a Rackspace Sales Representative, servers are physically located in any of three datacenters: [[Chicago|Chicago, IL]], [[Dallas|Dallas, TX]], or [[London|London, UK]]. Separate accounts are required to utilize servers on separate continents. Cloud Sites are not currently available from the London datacenter.

== Control Panel ==
[[Image:Rackspace Cloud control panel screenshot.png|right|300px|thumb|Rackspace Cloud online control panel]]
The online control panel was custom built by and for the Rackspace Cloud service (as opposed to using control panel software like [[cPanel]] as is often the case with traditional [[web hosting]] providers).

The control panel includes management interfaces for the Cloud Sites, Cloud Servers and Cloud Files services. There was once a web based file manager, but this was removed for undisclosed reasons. It also allows users to manage multiple clients and the plans and products (e.g. databases, 24x7 support) that apply to them, with white label branding options for messaging. The clients themselves have access to a restricted version of the control panel that allows them to conduct administrative tasks such as managing mail accounts.

The control panel is also home to the billing and reporting functions and provides access to support materials including developer resources, a knowledge base, forums and live chat.

== OpenStack ==
In 2010, RackSpace contributed the source code of its Cloud Files product to the [[OpenStack]] project under the [[Apache License]] to become the OpenStack Object Storage component.
