Change is a good thing. Unfortunately, when you are making big changes to your site or application, there is always room for error. Live-state snapshots takes the idea of a "backup" and takes it forward to its next logical step. Taking a snapshot of your partition not only creates a backup of your files, but also all of the processes running in the background at that instant in time. This way, if you make an error or break something while making updates, you can revert your partition to that exact snapshot, providing a working, fail-safe rollback.
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?
Included IP addresses are provided for free but on a need basis. ARIN rules require actual usage of an IP address so you must submit the domain name associated with any additional IP addresses. Additional IP addresses above the included IPs are available - please call our sales staff for pricing depending on number of IPs required. Limitations apply and this is no guarantee of availability.
You may also think that since you've customized your VPS, that you're stuck with the resources that you originally selected when you created your account. That's not true either. If you need additional resources after signing up for your account, that's just a sign that your site is growing. It's a sign of success. You shouldn't be penalized because for this success. That's why our VPS plans are completely scalable. Just contact our support team when you need more resources and we'll be happy to help.
I'v tested some other top VPS Providers/resellers (AWS, Digital Ocean, Vultr, etc.) and find that VPSServer.com offer highest performance/price ratio on market. One of the highest (top 3) IOPS, Unixbench and Network perfomance at lowest price from my research. Setting up server with operating systems is matter of few minutes. Managing is simple and clear.
Sometimes you need more power than an entry-level web hosting service can provide. If you're looking to take your business online and want to build your website on a server that offers more power, stability, and flexibility than shared hosting, but you don't want to pay the higher cost of dedicated hosting, VPS, or virtual private server hosting, may be the perfect middle-of-the-road service tier for your business.
Partitioning a single server to appear as multiple servers has been increasingly common on microcomputers since the launch of VMware ESX Server in 2001. The physical server typically runs a hypervisor which is tasked with creating, releasing, and managing the resources of "guest" operating systems, or virtual machines. These guest operating systems are allocated a share of resources of the physical server, typically in a manner in which the guest is not aware of any other physical resources save for those allocated to it by the hypervisor. As a VPS runs its own copy of its operating system, customers have superuser-level access to that operating system instance, and can install almost any software that runs on the OS; however, due to the number of virtualization clients typically running on a single machine, a VPS generally has limited processor time, RAM, and disk space.
