f. In a few minutes, the Instance State column on your instance will change to "running" and a Public IP address will be shown. You can refresh these Instance State columns by pressing the refresh button on the right just above the table. Copy the Public IP address of your AWS instance, so you can use it when we connect to the instance using SSH in Step 4.
I was in a similar situation about a year ago, had a managed VPS for some years before i needed a better server and had to switch to an un-managed VPS. Although i had another un-managed VPS without a control panel previously, this time round i chose an un-managed box with cPanel already installed. This was quite handy as i didn't have to deal with installing and licencing the control panel. As have always used cPanel, setting up sites, databases, DNS and all the other configurations was straight forward and fast.
cPanel and WHM give you all the power you need when managing multiple sites, domains and clients. Create as many cPanel accounts as you need within WHM's account dashboard, assigning the cPanels to each respective property. Once set up and assigned, you can view usage, manage account stats, modify, upgrade or suspend accounts and much more. This allows you to manage your server exactly how you want it, including splitting your clients up for billing, resource and support purposes.
To break things down a bit, cloud VPS (Virtual Private Server) hosting is when a web hosting provider takes one massive server and partitions it up so that it can have several servers on it, each of which can run its own operating system and can be re-booted independently.  Sounds simple enough.  So what is the difference between managed VPS and unmanaged VPS?
Similarly, in a real dedicated server, you will pay for the entire server that is not shared with anyone else. You will get complete control over all services. Unfortunately, it is also the most expensive hosting option and needs some technical expertise to manage. It is commonly used by those who have websites with specific scenarios, most commonly extremely high traffic and tight security requirements.
If you already have a number of clients hosted with various other cPanel-based hosts, our VPS Hosting plans all come with Launch Assist, 2 free hours of time with our System Administrators that can be used for migrating your sites. cPanel also has a powerful interface for transferring multiple accounts, providing you have root and SSH access to your current server. This transfer tool, which has step-by-step walkthrough and documentation on the cPanel site, was created to help designers, developers and agencies to quickly and easily move a number of accounts from one server to another.
The force driving server virtualization is similar to that which led to the development of time-sharing and multiprogramming in the past. Although the resources are still shared, as under the time-sharing model, virtualization provides a higher level of security, dependent on the type of virtualization used, as the individual virtual servers are mostly isolated from each other and may run their own full-fledged operating system which can be independently rebooted as a virtual instance.
