CloudLinux Releases New Technical White Paper

CloudLinux has released a technical white paper, "How to Squeeze More Efficiency Out of Your Infrastructure." The paper details current inadequacies in the hosting arena and how the CloudLinux Operating System (OS) effectively addresses these issues. In particular, with CloudLinux technology, the study proceeds to explain how web hosts can double the density of their shared hosting servers while simultaneously improving server stability.

The proprietary research conducted by CloudLinux was meant to provide evidence of the inadequacies of existing server management techniques. Included is a detailed analysis of the two research methodologies used: a statistical analysis of server log activity and a survey of the experiences of real world hosting providers.

The study details the impact on hosting providers who, today, lack the ability to optimize the number of clients on a server due to risk of increased instability. Key findings include:
- 46.6% of web hosts reported they experienced downtime due to a lone site at least a few times a month
- Frequently a single site or a very small number of sites utilize a disproportionate amount of resources:
o Top 1% of sites are responsible for 39% of the static requests (on average) to the server
o Top 5% of sites are responsible for 65% of static requests (on average) to the server
- On 25% of the servers analyzed, top 1% of the sites are responsible for 50% or more of dynamic requests to the server

Reasons for server spikes which can bring down an entire server can include:
- One badly executed script on one site
- New software introduced to a site
- To mitigate some of these risks, many hosting providers keep server capacity at 60% or below in order to maintain stability, but they sacrifice optimizing their infrastructure in the process. This is the problem that CloudLinux solves with its new Lightweight Virtual Environment (LVE) technology. It has the capability to vastly improve the density of shared hosting servers, often enabling hosting providers to double server density without sacrificing stability. The benefits of this approach include:
- Properly manage hundreds or thousands of websites simultaneously on one server without risking server stability
- Prevent one site from affecting the performance of other sites on a server
- Gain control and manage server resources down to an individual site level, versus a server level
- More quickly identify sites which are not functioning properly without running the risk of a single site slowing or taking down a whole server

The release of this white paper comes at a critical time. With the growing demand by websites to run a new array of rich applications and cloud services in a stable server environment, data centers and hosting providers are challenged to provide the quality service these customers require, cost effectively. With the CloudLinux LVE technology, hosting providers can introduce a new level of flexibility that optimizes their infrastructure.

CloudLinux OS is a solution designed to improve control in the shared hosting and data center arena, while simultaneously increasing control and stability, as well as improving overall performance. For a free copy of the white paper, go to
