cloud vs colocation

Sh*ts

I’m gonna let here some paragraphs of a nice article from serverdensity.com geeks blog, explaining their choices/ideias cloud vs rented vs colocation with their point of view is also the same that I have about getting our own servers instead of use clouds or rented servers –

Before the paragraphs from serverdensity i’m gonna let some maths that i’v made 3 weeks ago… rackspace vs our own servers (dell).

rackspace clouds with 2Gb RAM / 80Gb disk – web and sql vs colocation dell 2Gb RAM / 500Gb disk and rackspace clouds with 8Gb RAM / 320Gb disk – web and sql vs colocation dell 8Gb RAM / 500Gb disk

rackspace – Performance Cloud Servers

Sh*ts

 

Compared to existing cloud servers, Rackspace said its new servers offer 4x more total RAM, 2x more total CPU performance, and 132x more total disk I/O, and are specifically designed to work with Cloud Block Storage.

Powered by OpenStack, performance Cloud Servers are designed with RAID 10-protected solid state disks, Intel Xeon E5 processors, up to 120 GB of RAM and 40 Gigabits per second of network throughput, according to the announcement.

 As seen on: http://www.thewhir.com/web-hosting-news/rackspace-updates-public-cloud-servers-for-speedy-application-performance

 

As for pricing, Rackspace has dropped the price about 33 percent, in addition to the upgrading its cloud architecture.

ZeroVM – The Cloud Hypervisor

Sh*ts

ZeroVM is efficient because it is made to virtualize applications, not machines. The runtime virtualizes only the server parts that do the actual work at hand – making it much faster. Today, the fastest virtual servers take at least two minutes to create, while ZeroVM takes less than 5 milliseconds – or 1/20,000th as long. ZeroVM is fast enough that you can put every request into its own mini-VM to spread horizontally.

Making things smaller, lighter and faster also provides greater security. ZeroVM is fast enough to isolate each individual user in a separate container, which delivers greater granularity of security and control.

Rackspace announced on Monday that it has acquired ZeroVM, a lightweight open-srouce hypervisor created by LifeStack

HHVM by Facebook

Linux

HHVM is a new open-source virtual machine designed for executing programs written in PHP. HHVM uses a just-in-time compilation approach to achieve superior performance while maintaining the flexibility and ease of use that PHP developers are accustomed to (dynamic features like eval(), rapid run-edit-debug cycle, etc).

HHVM is used by Facebook to serve billions of web requests per day. To date, HHVM has realized over a 9x increase in web request throughput and over a 5x reduction in memory consumption for Facebook compared with the Zend PHP 5.2 engine + APC.
