If you need a 100% Uptime SLA then eUKhost's cloud servers are the solution for you. Some companies or individuals need to know certain processes are in place to ensure that their website or application will remain online during events which would take a standard server environment offline. These things are numerous in nature but include disk drive failure, individual server component failure or switch failure. Any of these incidents could take a traditional hosting product offline, our VMWare and HyperV Cloud Hosting plans consist of a clusters of servers connected to a remote storage device with data striped down multiple devices, multiple switches and network uplinks.
These clusters are housed in a Tier 4 facility, rated N+N for power and network connectivity. A tier 4 facility is the highest rating available and as such we are able to offer certain levels of service which lesser rated facilities are unable to offer. The facility is manned 24/7 by experienced support engineers to ensure that the environment runs smoothly. For our latest clusters we are using Dell R610 Dual Quad and Hexa-Core Processor servers, with 96 GB RAM in each. Each server is configured in RAID and is dual powered from two separate power feeds. We use redundant 10 Gbit Arista switches for our internal network and an EMC Isilon storage cluster for the remote storage device.
VMWare is the ideal choice for our Linux range as it has a proven track record for reliability, scalability and performance. In our High Availability clusters we typically keep 45% of the overall resources available to ensure that we have both enough capacity for failover and also to accommodate client upgrades. As a result of our software choice we can perform maintenance operations without clients experiencing downtime. This is achieved by performing both live host (physical server) and live storage migrations (disk drives).
HyperV is the ideal choice for our Windows range as it offers a similar level of reliability as VMWare and, in our internal tests, performed better when running Windows 2008 on VMs. As with our VMWare range, we can perform live storage and host migrations, while ensuring that your VM stays online. As a result of competitively priced software from Microsoft, we can offer Windows Cloud Hosting at a very similar price to our Linux Cloud Hosting.
With all of our Cloud Hosting Plans a 100% uptime SLA comes as standard. With our 100% Uptime SLA in place, and because we are so confident in our products, we will give performance credits, as described in our SLA, if there is even a second of downtime on our Cloud Infrastructure.
I refer to the above from EUKHOST. We've been on the linux cloud system for a few years now. In the main, things have been ok. The odd downtime but nothing too drastic. Our sites are very much stable in terms of usage and resource requirements which is why over the past couple of months, I have become annoyed at the frequent issues we are encountering with the system. I guess my topic points towards my confusion because one would assume such issues are accounted for within 'the cloud'.
Firstly, CPU and Memory Load. If the cloud is supported by up to 8 cores and up to 12MB ram why is it stated in the WHM that there is just one CPU and 1GB Ram on the system. We have found that load is pushing these system resources of late and hence, the server has been seriously lagging. To the point at which customers have complained. Why at times of high load are resources extended accross the advertised 12gb ram or multiple CPU's? Is this some sort of upgrade that is required to utilise this extra power?
It is also frustrating when certain support staff fail to offer a full explanation as to what might be going on.
I guess what I would like to know is whether we are on the right system because if the Cloud does not offer the service we require then we are better off trying to find something that will suit it.
Thanks
