Cloud Servers Explained
Cloud Servers are a new, affordable way to get the cloud's computing power for your websites or applications. Test drive Cloud Servers for a day with the change lying down the back of your couch. 30 days risk free.
Each Cloud Server is a fully-customizable, pay by the hour, virtualized server instance that you launch, maintain, and control with full root access.
Imagine being able to provision a server in minutes. To upgrade it automatically. To bring servers up and down as needed. This is the idea behind Cloud Servers. Totally customizable, each Cloud Server gives you full root access to the Linux distribution of your choice. You pay depending on how large a server you buy.
Based on Xen Virtualization technology, Cloud Servers brings the power of the cloud to the traditional server hosting based model. Just like a dedicated server, your Cloud Server provides total flexibility for you to run anything you want from a Java website to a Ruby on Rails application.
The Power of The Cloud
Scale resources across leading hardware architectures, bandwidth and storage to meet the needs of your job or service. Add a node when you need it or scale down when you need to.
Control your data, your applications, your dedicated Cloud Server, when you need it - and only when you need it.
Free your company from IT Infrastructure constraints, from long term contracts, from Capex and management nightmares.
Fault Tolerance within the Software Layer
Unlike legase infrastructures with hardware bearing the brunt of fault tolerance, the cloud infrastructure places all fault tolerance within the software layer itself. This accomplishes many things, the most beneficial of which is that load balancing can now be more intelligent overall and failover (fault tolerance) response is quicker.
Why Cloud Computing?
There are reasons aplenty to stick your head into cloud computing, says Forrester Research Inc. analyst James Staten. IT can't keep up with the demands of the business. The best Web services companies have maxed out their data centers for efficiency, and those babies can handle almost anything you throw them. You pay by the drink. You are free of long-term contracts. Most cloud vendors let you come and go as you please, Staten said. And all you need to do is log in.
- Capacity planning is hard to do: Of course, you want to provision IT at Internet speed, but figuring out whether the data center can hold another service, and where that service should go and what needs to be moved to make room for it, takes time. Also, there is a dearth of good tools to do this.
- Catch-22: You have vowed to keep up with the business, but "just give them another server" doesn't cut it anymore, because IT must control spending.
- The Biz wants a down-and-dirty prototype -- nothing big or fully baked: So, again, why can't IT squeeze in this modest proposal? Because it's hard to fit it in. (See No. 1) Security reasons also make it hard for you to set up an outside play area for them to kick around the idea.
- The data centers of the big Internet services providers, such as Amazon Web Services, Salesforce.com Inc. or Akamai Technologies Inc., are better than yours. "Vastly superior," team Staten says. Economies of scale can get you a real deal on the economics of running a data center, not to mention kid-glove treatment from sharp-clawed hardware, software and maintenance vendors.
- Their data centers are better than yours, part 2. Big Internet service providers have not only better processes but also management and administration tools that, almost like magic, can spread applications across thousands of servers and scale them quickly, reminds Staten. (For more on these points, Staten suggests you read Amazon CTO Werner Vogels' blog, All Things Distributed.

Features of Cloud Servers
Instantly Scalable
Cloud Servers put you in complete control of your hosting infrastructure. Each Cloud Server is a fully-customizable, pay by the hour, virtualized server instance that you launch, maintain, and control with full root access. Cloud Servers has guaranteed minimum CPU power (relative to the size of the Cloud Server), with free bursting when extra capacity is available on the host.
High Availability
Each Cloud Server comes with the simplicity of a dedicated and persistent public IP address (no NAT) with a second, private IP address for free, low latency bandwidth between your Cloud Servers. Additional public IPs are available upon request and shared IPs can be provided for high availability.

Persistence
One of the most significant differences between Cloud Servers and EC2 is the persistence of each virtual server. Cloud Servers has access to local, RAID10 disk storage, much like you'd expect in a physical server. This is important because it means your Server has inherent protection against drive failures. If for some reason the host does fail or become degraded, we will restart and/or migrate your Cloud Server for you. A failure doesn’t mean that your Cloud Server goes away.
Server Sizes
We provide a wide variety of Cloud Server sizes, starting at 256MB going up to 15.5GB. Cloud Servers can be resized to scale up or down without any reinstallation.
CPU Scheduling
Cloud Servers has guaranteed minimum CPU power (relative to the size of the Cloud Server), with free bursting when extra capacity is available on the host.
IP Addresses
Each Cloud Server comes with the simplicity of a dedicated and persistent public IP address (no NAT) with a second, private IP address for free, low latency bandwidth between your Cloud Servers. Additional public IPs are available upon request and shared IPs can be provided for high availability.

SLA - Service Level Agreement
Network
We guaranty that our data center network will be available 100% of the time in any given monthly billing period, excluding scheduled maintenance.
Data Center Infrastructure
We guaranty that data center HVAC and power will be functioning 100% of the time in any given monthly billing period, excluding scheduled maintenance. Infrastructure downtime exists when Cloud Servers downtime occurs as a result of power or heat problems.
Cloud Server Hosts
We guaranty the functioning of all cloud server hosts including compute, storage, and hypervisor. If a cloud server host fails, we guaranty that restoration or repair will be complete within one hour of problem identification.
Migration
If a cloud server migration is required because of cloud server host degradation, we will notify you at least 24 hours in advance of beginning the migration, unless we determine in our reasonable judgment, that we must begin the migration sooner to protect your cloud server data. Either way, we guaranty that the migration will be complete within three hours of the time that we begin the migration.
Credits
If we fail to meet a guaranty stated above, you will be eligible for a credit. Credits will be calculated as a percentage of the fees for the cloud servers adversely affected by the failure for the current monthly billing period during which the failure occurred (to be applied at the end of the billing cycle), as follows:
Network: Five percent (5%) of the fees for each 30 minutes of network downtime, up to 100% of the fees;
Data Center Infrastructure: Five percent (5%) of fees for each 30 minutes of infrastructure downtime, up to 100% of the fees;
Cloud Server Hosts: Five percent (5%) of the fees for each additional hour of downtime, up to 100% of the fees;
Migration: Five percent (5%) of the fees for each additional hour of downtime, up to 100% of the fees.
Definitions: For purposes of this Service Level Guaranty:
- "cloud server" means your unique virtual machine instance;
- "cloud server fees" means the fees for your cloud servers for the monthly billing period in which the failure occurred and includes monthly virtual machine instance and bandwidth charges;
- "cloud server host" means the physical server which hosts your cloud server;
- "data center network" means the portion of The Rackspace Cloud network extending from the network egress point of your cloud server host to the outbound port of the data center border router;
- "power" includes UPSs, PDUs and cabling, but does not include the power supplies in cloud server hosts;
- "scheduled maintenance" means maintenance that is announced at least ten business days in advance, and that does not exceed sixty minutes in any calendar month.
Limitations.
You are not entitled to a credit if you are in breach of your services agreement (including your payment obligations to us) until you have cured the breach. You are not entitled to a credit if downtime would not have occurred but for your breach of your agreement with The Cloud or your misuse of Cloud Servers system.
To receive a credit, you must contact our account team within thirty (30) days following the end of the downtime. You must show that your use of the Cloud Servers was adversely affected in some way as a result of the downtime to be eligible for the credit.
This Service Level Guaranty is your sole and exclusive remedy for Cloud Servers unavailability.
Notwithstanding anything in this Service Level Guaranty to the contrary, the maximum total credit for the monthly billing period, including all guaranties, shall not exceed 100% of your fee for that billing period. Credits that would be available but for this limitation will not be carried forward to future billing periods.
This Service Level Guaranty is part of your Agreement with The Technomax Group (a Rackspacetm Partner), along with The Terms of Service and the AUP below, and is subject to the terms and conditions stated in those documents.

Backup Pricing for Cloud Servers
We offer full image backups on our 256 MB, 512 MB, 1024 MB, and 2048 MB Cloud Servers. Full backups of your Cloud Servers are priced according to the amount of data you are backing up. At any time, there are three backups stored - a daily, a weekly, and a variable backup - and these backups stay attached to the server unless that server is resized above a 2048 MB Cloud Server or until it is deleted. A backup can be used to restore a server or a new server can be cloned from the backup.
For now, backups for 256, 512, 1024, and 2048 Cloud Servers are free of charge.
Soon all servers will support backup. Backups will transfer over to Cloud Files free of charge. Once there, the storage costs only 15¢ per GB (for as much storage as you need), and 1¢ per 500 requests.
