Free web hosting is not reliable. Web space is small, slow speed, sharing a server with lots of people.. the only advantage for free web hosting is “FREE”.
If you like to have a low cost web hosting, i would recomand you to use shared hosting and get 4 months free. This will be much more powerful than free hosting.
Shared Hosting
The shared web hosting is an inexpensive entry point for low traffic websites, running within the setup constraints of the standard accounts. As some sites expand, the shared hosting accounts become limiting.
Dedicated server
Performance – You are not sharing the system resources such as processor power, memory and disk space with other sites on the same server.
Greater Reliability – You do not run the risk of the server being slowed down, swamped with traffic, or crashed by another site on a shared server.
Security – As nobody else has access to the server you can be sure of having a much greater degree of security.
Custom Configuration – If you need to install special software or configure the server to your own particular needs then often a dedicated server is the solution.
Custom Firewall – Run your own custom firewall to enforce your own access control policy.
Your own IP address – Most shared hosting sites share a single IP address, with site traffic directed by the server examining `host headers’. In contrast your dedicated server has its own unique IP address.
Upgrade Path – More memory, disk space or extra processors can be added as the need arises.
