SiteGround cloud hosting

SiteGround cloud hosting uses a highly advanced virtualization system which guarantees that no website will be affected by other users on the same cloud. This guarantees a dedicated server-like feel and yet allows us to offer flexible Cloud hosting plans, suitable for smaller websites too.

VMware Ready VMs

VMware Ready Virtual Machine (or Virtual Appliance) begin with qualifying a VMware Ready product. Members of VMware’s Technology Alliance Partner (TAP) program can download the VMware Ready Program Guide and begin testing their product for this qualification.

There are a few dozen VMware Ready VMs at http://www.vmware.com/appliances/directory/cat/521

Amazon's AWS EC2 Micro instance performs like a Nokia N900

According to Phoronix Performance Benchmarks Amazon’s AWS EC2 Micro instance performance is more similar to a Nokia N900 than an Intel Atom !

For comparison we included the results from this small set of cloud computing tests to that of the Nokia N900 (yes, really, the smart-phone) running Maemo 5, and the Dell Mini 9 netbook with an Intel Atom N270 CPU, 1GB of RAM, 8GB SSD, and it was running Ubuntu 10.10.

Apparently new customers to Amazon’s EC2 cloud get one year free of EC2 Micro usage using a Linux/Unix AMI (Amazon Machine Instance). An Amazon EC2 Micro instance has 612MB of memory, up to two EC2 Compute Units, 32-bit or 64-bit support, and is rated for low I/O performance. The compute power of a micro instance varies depending upon the workload and availability of resources in the cloud where small bursts up equivalent to two EC2 Compute Units are available for short periods. With this Amazon cloud computing performance measurement, one EC2 Compute Unit is equivalent to a 2007-era 1.0~1.2GHz AMD Opteron or Xeon processor. So not only is the micro instance slow, but its performance varies from time to time, which is also bad for reproducible benchmarking.
