Virtualization

Beside the very specific solutions that we've pointed in the three previous solution description, we have also a strong expertize into design, implementation and follow-up of virtual infrastructures.

Our mainstream expertize is in the field of Open Source solutions, but we are not bound to it in this field and we hav also expertize with commercial software. We have successfully deployed environnements based on solution like :

• the Open Source virtualization platform KVM
• VmWare Virtual Infrastructure

By extending our expertize to other solutions, we are able to propose a valuable approach, taking into account the pro's and con's of each solutions.

As virtualization Open Source solution, we've chosen KVM, the multi-awarded solution that has aleady been choosed by a lot of companies as their virtualization solution. KVM has the advantage to run in a so-called paravirtualization mode. This means that the Operating System running in the virtual machine (the Guest) is aware that he's running in virtualization plateform and therefore almost runs with the same performances as it was on a physical machine. If the performance is a key factor for your application, this is the solution to use, better than the one offered by VmWare. The disadvantage of this method beeing that only altered Operating System (like Linux) can run in this kind of virtual machine.

Of course, there is an alternative to run unmodified Operating Systems on KVM, this is full-virtualization mode, where the guest OS is not aware that is running into a virtual machine. In this mode, we can run guest Windows virtual machines on our KVM plateform. This mode is achieved by using the Virtualization Technology (VT) which is now present in each recent Intel or AMD CPU's.

Beside the KVM plateform itself, we will use the Open Source libvirt environment system to build management and automation solution. Using tools like virsh or the graphical virt-manager, we will be able to provide a rich management infrastructure.

Migration & integration

Of course, you already have your infrastructure in place. But you would like to improve and to change, without worry.

Don't think that because you are running Windows servers you cannot use some Open Source products next to them. Here, at OneBit, we are expert in the field of integrating together what seems at first sight not integratable. By using solutions like Samba or OpenLDAP, we are able to build an infrastructure where any user, should he/she runs a Windows or Linux based PC won't see any difference in what he's able to do :

• access to file and print services
  
• central directories
  
• central authentication (the same password everywhere)
  
• documents management

Or you may have decided to replace expensive commercial software by a equivalent cheaper Open Source solution. But you don't know by which end to begin, you don't even know which solution to choose.

In this case, don't worry, our experts are there to help you from the begining to the end of the process :

• assesment of the current infrastructure and of your business to list your needs
  
• selection of the suitable Open Source solution
  
• creation of a proof of concept (POC) to show you the advantages and disadvantages of each solution
  
• prepare the migration from the old to the new solution
  
• assist your IT staff during each step of the process, providing on-site knowledge transfer from the begining to the end
  
• train the administrators, the users or even your own trainers
  
• follow up with you once the new solution is migrated up and running
  
• providing advices during the exploitation phase to help you to magnify your investment
  
• propose preventive and curative maintenance to let your business runs smoothly

With the combination of the power and the flexibility of management systems like PhpLdapAdmin and Webmin, you don't have to worry if you don't like the command tool to manage tons of systems. Thanks to the Open Source model, we can extend these management tools to completely suit all of your needs. You won't be required anymore to adapt our organization to your tools.
