Cloning of servers is a function that was first introduced back in Q1 2010. The cloning function has not been given the attention that it deserves until now.

Did you know that you can clone your servers in City Cloud?
Wednesday, August 11th, 2010Hardware problems explained
Monday, August 9th, 2010While in beta we have had great hopes of sticking very close to 100% up time in City Cloud. However yesterday (Sunday) we had our longest outage where some customers were out of service for as long as 10-11 hours. Completely unacceptable of course – in particular in a service were we want to set a new standard for up time. With this blog post we want to spend a few minutes giving more detail as to what happened.
Ubuntu 10.04 64bit, now available in City Cloud
Friday, July 16th, 2010
We are working as fast as we can to deploy new and updated Operating Systems. During this week we have been working hard to make Ubuntu 10.04 64bit available in the App Center and now it´s ready!
Microsoft Windows Server 2008 R2 in City Cloud!
Monday, July 5th, 2010
At the beginning of last week we performed major upgrades to our City Cloud service. One week later we are happy to present a new Operating system in the App Center, Microsoft Windows 2008 R2.
Upcoming changes in the City Cloud service
Friday, June 18th, 2010We would like to thank all of our users for the feedback you have given us since the launch of City Cloud back in November 2009. We have listened to you and now it´s time for the biggest update in the history of City Cloud!
On Monday the 28th of June between 00:01 and 06:00 the Cloud Computing service, City Cloud, will go through some important changes in order to improve our service.
The changes are made in the architecture to improve stability and performance. The update will also improve other areas such as compatibility. New and updated Operating Systems will soon be available as images within the service.
What will be launched
- Performance and stability enhancements
We are doing a total rework of the Storage subsystem providing storage space for all City Cloud customers. The new system will provide much better performance and with that comes better reliability. Also we switch from the Xen hypervisor to using KVM instead which will also improve performance. - Compatibility
The switch from Xen to KVM also means we’ll be able to provide a wider range of OS images. Immediately after the upgrade we will start upgrading OS versions (for example to Windows 2008 r2 and Ubuntu 10.04). - New Operating Systems
Also completely new images will be provided shortly after the upgrade. For example FreeBSD and NetBSD. - User Interface upgrades
Providing a number of useful features for customers including the ability to add and remove extra storage devices to existing VMs, improvements in the listing of running VMs in the UI, control of more advanced tunables for each VM, and a range of other improvements.
What´s been keeping us busy
- Migration to ZFS
The new storage system is based on ZFS which provides lots of features that are useful in this environment. For example deduplication means that the available storage will be used more efficiently, block checksums makes detection and correction of silent data corruption possible and the I/O performance will also get a significant boost. - Switch from Xen to KVM
As mentioned above this will widen the range of Operating system images we’ll be able to provide. Also it will significantly improve network performance. The user interface, APIs and such will not be changed due to the switch so from a customer perspective everything will work as before, only better. - Backup service
We already have backups for disaster recovery, but are also working on a customer administered file backup system enabling users to install a small client in the VM and configure their backup needs and pay per megabyte. We will get back to you with more information on this. - Firewall service
Today customers requiring firewalling of their services can use the built in firewall of the operating system of the VM. We are working on a more centrally administered firewall service for all City Cloud customers providing simple firewall configuration. We will get back to you with more information on this as well.
Nobel wins a prize from City Network
Wednesday, May 5th, 2010Last week we showed off our cloud computing service, City Cloud, at Cloud Conference in Stockholm. We met a lot of companies and curious visitors who were there to add to their knowledge of cloud computing during two intense days. We got the chance to present our powerful but easy to use cloud computing service for many medium to large companies around Europe. Our visitors certainly found City Cloud to be really interesting and our presence was a success with many contacts leading to new users in City Cloud. Did you know over 500 companies are now using City Cloud?
During the conference we held a contest in wich the grand prize was 10 000 SEK worth of cloud computing power – in City Cloud of course.
We now have a winner and the winner is… Nobel Web AB!
Nobel Web runs the official homepage of the Nobel Prize, Nobelprize.org. On their website you can find all the information about the Nobel prize, the nominees and all kinds of information about their work.
Once again, Congratulations Nobel Web AB!
