Complete Software Control

Compare Computing Clouds
Free choice of operating systems
CloudSigma places no restrictions on the operating systems that run on the virtual server instances. We offer Windows cloud servers and Linux cloud servers and other operating systems of whatever version without issue. Cloud servers come with full administrator/root access also making them ideal platforms for reseller web hosting such as CPanel or Plesk. Any operating system will run on the CloudSigma platform as long as it is compatible with standard Intel/AMD architecture.
Flexible non-bundled resource sizing
CloudSigma aims to make its IaaS cloud computing offering as close to true utility computing as possible. Unlike most other IaaS platforms, our cloud servers allow users to make virtual server instances with exactly the combination of CPU, RAM, storage and bandwidth that they require. We never bundle resources together allowing our users to buy only what they need and eliminate waste. As a cloud computing provider we aim to delivery flexible cloud computing services.
Persistent storage and servers
All virtual server instances at CloudSigma are fully persistent just like standard dedicated servers. Whether a cloud server is running or stopped, all the settings, network parameters and drive associations persist. A cloud server is only removed from an account when the account owner deletes it.

All storage in the CloudSigma cloud is persistent. Storage is available in the form of drives which are created by the user. A drive‘s data is persistent whether associated or not with a server and whether or not a drive is mounted. Storage data is only removed from an account when the account owner deletes a drive.
Short 5 minute billing cycles
As a cloud computing provider, CloudSigma is fully committed to making sure our customers only pay for what they use. We calculate resource usage using rolling 5 minute billing periods. It means we calculate your usage every five minutes and that is the amount you will be charged for five minutes only. Many other IaaS cloud computing providers charge a minimum of 1 hour based on your peak usage during that time even if that server is off for most of that period!
100% AES 256bit Encrypted Storage
All user virtual drives have the option of being encrypted using a 256bit AES-XTS encryption cascade automatically. Encryption of drives prevents data leakage of deleted drives at a later date. This measure protects 'data at rest’ within our cloud hosting. This protection forms a critical part of our privacy policy and comprehensive cloud computing security framework.
Fast continental European location
CloudSigma’s cloud servers are located in Zurich, Switzerland, at the heart of Europe. We are a native European cloud hosting provider. Based at the Interxion Carrier Neutral data center in Glattbrugg, we are able to choose from 37 different IP connectivity providers. This means we offer some of the most competitive data transfer pricing of any IaaS cloud computing provider as well as totally free, unlimited incoming bandwidth. In addition we have enviable (redundant) networking performance throughout Europe and beyond.
