TMDHosting announced a significant change in the VPS and managed Cloud hosting infrastructure at TMD Hosting, as they switch from using OpenVZ to KVM. TMDHosting has been using the OpenVZ technology for their VPS and Cloud service needs for some time now; the OpenVZ technology was initially chosen for its streamlined management and a relatively easy networking setup. This allowed for greater automation and hardware node based scalability.
TMDHosting Moves From OpenVZ to KVM
TMDHosting discovered that there were some issues in the OpenVZ architecture but always managed to overcome them. Despite working extremely well for some time, they could not use it to pool idle CPU resources or flexibly allocate RAM. With alternatives that could do these things, OpenVZ started to become very inefficient.
TMDHosting began looking for solutions to take advantage of these idle CPU resources, and after some investigation found that KVM was the solution. This allowed a move from a single infrastructure configuration to a multiple infrastructure configuration, allowing full utilization of all their available resources in a pool to be used across all VPS and Cloud instances.
TMDHosting tests show (see chart above) that the changes may bring at least 100% increase for page load times, by putting idle resources to use. It matters a lot how fast website data is being read from the storage, and by reducing this time, they reduce the time it takes for a page to load.
They did a simple test to make sure that this difference was going to help their customers, which you can see in the chart below:
This new measures should boost performance by more than 300% at no extra cost.
The new infrastructure will be divided into three segments. This allows them to pool the resources and divide them flexibly between the different instances.
- Network resources
- Computing (CPU)
- Disk storage (i.e. customer data)
By combining them together in a flexible, adaptive way, the CPU is allocated much more efficiently. This means no over allocation of resources, and equally, the moment more resources are need they can be scaled automatically to ensure smooth running of the hosting service.
This is an enormous change for the TMDHosting infrastructure, and the company has planned to migrate their existing VPS and Cloud instances first, beginning in the next week. Then, TMDHosting will be covering various aspects of the infrastructure upgrade, such as hardware configurations, networking setup, the process of migration and other advantages of the new platform via their blog. A precise schedule for VPS and Cloud migrations is currently being prepared by the TMDHosting operations team, and every customer that is going to be migrated will be notified personally by the company.
