koding.com has a free VM running Ubuntu. The specs are pretty good, 1 gig memory for example. They have a terminal online you can access through their website, or use SSH. The VM will go to sleep approximately 20 minutes after you log out. The reason is to discourage users from running live production code on the VM. The VM resides behind a proxy. Running web servers that only speak HTTP (port 80) should work just fine, but I think you'll get into a lot of trouble whenever you want to work directly with other ports. Many mind-like alternatives offer similar setups. Good luck!

Cloud hosting: This type of hosting is slightly more expensive than shared hosting (similarly priced to VPS hosting). Rather than using a single server to store and load your site, a cloud system distributes resources across many different computers for faster response times. However, this model typically doesn’t give you root access, and its distributed structure presents fundamental security challenges.
Most people are clueless about the virtual servers hosting and how they actually work on the shared environment. It is a known fact that thousand and more number of users tend to use a server at a time. In such circumstances, each user is allocated with a designated amount of disk space, bandwidth, CPU allocation, memory and Operating System, which can be used on the server. All the Virtual Private Server users share the same CPU and RAM and think that, they have dedicated set of hardware. Virtual Server software is loaded onto the physical system and from then, a virtual server is ready to be used.
A VPS hosting provider relies on virtualization software, called a hypervisor, to abstract resources on a physical server and provide customers with access to an emulated server, called a virtual machine (VM). Each virtual machine runs a complete operating system, and has restricted access to a portion of the physical server's compute, memory and storage resources. Customers have access to the VM's OS, but not to the physical server.
Perhaps the best way to approach the virtual server is the idea of a virtual machine. A VM allows you to run an emulation of a computer within your computer, drawing on the resources of the physical one –  disk space, RAM, CPU, etc. This tactic allows you to run an entirely separate operating system (OS) solely for the purposes of the VM, even if its type and version of OS are identical to what’s on your hardware.

The choice you have to make between managed and unmanaged VPS hosting depends on several factors. Your skill in handling the server is an important factor. The efficiency in dealing with the complicated aspects of server hosting is necessary when you lack a manager to administrate the VPS hosting server. The strength of your business in terms of the profit is another important aspect. Considering all these factors, it is always advisable to seek higher opinion in your choice of a web hosting server.
A VPS runs its own copy of an operating system (OS), and customers may have superuser-level access to that operating system instance, so they can install almost any software that runs on that OS. For many purposes they are functionally equivalent to a dedicated physical server, and being software-defined, are able to be much more easily created and configured. They are priced much lower than an equivalent physical server. However, as they share the underlying physical hardware with other VPSes, performance may be lower, depending on the workload of any other executing virtual machines.[1]
