Which company offers the best VPS hosting?

VPS HOSTING IS A COST EFFECTIVE ALTERNATE OPTION TO DEDICATED SERVER HOSTING.

I’m using managed VPS service from Interserver https://www.interserver.net/dock/vps-344276.html and they are the cheapest and most feature rich in the market.
Unlike most of others they only use SSD hard drives which offers 20x more performance than SATA disk drives.

Their base plan starts from $6/m as compared to $19+/m from other players.

Main Features:

Instant Provisioning:
Get up and running in seconds. While most VPS solutions take hours or days to activate, Interserver has designed our VPS servers to provision immediately. Use your server the very second you need it.

High Performance Storage
20x faster than standard SATA disk drives, InterServer provides all new virtual private servers with high performance SSD hard drives that range from 30GB to 240GB.

99.9% Uptime Guarantee
Interserver guarantees hardware, network, and infrastructure uptime of 99.9%. If we ever fall short, you get money back. That's the Interserver 10/10 Uptime Guarantee.

Multiple language Servers
The latest versions of PHP, MySQL, Perl, Python, Ruby, and more come pre-installed. But you can customize your server with any Linux-based application, server software, or OS component.
