Both single-machine and cloud-based VPSes are managed using a software program called a hypervisor. The machine that runs the hypervisor is called the host machine and the individual virtual private servers are called guest machines or guest instances. The hypervisor can start and stop the virtual machines and allocates system resources, such as CPU, memory, and disk storage to each VPS.
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!
Amazon VPC provides advanced security features, such as security groups and network access control lists, to enable inbound and outbound filtering at the instance level and subnet level. In addition, you can store data in Amazon S3 and restrict access so that it’s only accessible from instances in your VPC. Optionally, you can also choose to launch Dedicated Instances which run on hardware dedicated to a single customer for additional isolation.
Way of using resources In the case of shared hosting, websites and / or applications residing on the server make use of resources and available server capacity at the same time. In the case of VPS hosting, each websites and / or applications residing on the server is being allotted a virtually distinct server. Here a separate, exclusive server is often rented.
Uptime: What is their SLA regarding up-time? Can you afford to have your business down for days?

Do you plan to sell products or services? If so, you'll want to invest in a web hosting service that offers Secure Sockets Layer (SSL). An SSL connection encrypts the financial information that shuttles between users' web browsers and your website, thus safeguarding the transmission of the purchasing information. Some hosting companies include a free SSL certificate when you sign up for a web hosting plan, while others charge close to $100. You can save some money by shopping around for services that offer the cheaper SSL plans.
– Error-proof sandbox – Virtual private servers give you “do-over” potential because they exist within a virtual sandbox. Damaging a virtual server won’t impact the operating system running on the hardware itself. “The VPS can be rebooted or reinstalled without much issue except maybe for lost data (so always keep backups),” notes Joel Lee of MakeUseOf. “On a dedicated host, a mistake could cause permanent damage.”
KVM’s popularity has been moving up on the list of virtual machine software’s due to its success with OpenStack.
