KVM’s popularity has been moving up on the list of virtual machine software’s due to its success with OpenStack. Marrying the 2 products together gives similar functionality as VMware vSphere, although there are some limitations with hosting Windows VMs, which are now taken care of by OpenStack’s ability to also support Hyper-V and ESXi.

With unmanaged cloud VPS hosting, the hosting provider is only responsible for the physical server and the availability of the server. This means that with the exception of the initial OS installation, the user is responsible for the maintenance, upgrades, installation of software, etc. If you choose unmanaged cloud VPS hosting, you should be familiar with the operating system and server software you choose to use.

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?
KVM virtualization gives customers more possibilities of management and server configuration. As it is a kernel based VPS hosting, kernels can be upgraded and modified by installing kernel modules. KVM has its own virtualized hardware, and the virtual server acts as a physical server. There is a possibility to set up a container-based system, such a Docker or Kubernetes to create OS level based containers on the KVM server.
You can use Amazon VPC to host multi-tier web applications and strictly enforce access and security restrictions between your webservers, application servers, and databases. You can launch webservers in a publicly accessible subnet and application servers and databases in non-publically accessible subnets. The application servers and databases can’t be directly accessed from the Internet, but they can still access the Internet via a NAT gateway to download patches, for example. You can control access between the servers and subnets using inbound and outbound packet filtering provided by network access control lists and security groups. To create a VPC that supports this use case, you can select "VPC with Public and Private Subnets" in the Amazon VPC console wizard.
Virtual Private Server (VPS) hosting definitely seems to be the future of the web hosting world. An unmanaged VPS hosting service is a solution that is completely under the control of the customer. Web hosting providers do not recommend such a service to people who don't know how to establish, manage, and function a web server; in such a case, managed VPS hosting provides a better solution.
Choose from a range of widely used Linux and Windows operating systems, including Windows Server 2016. Root access means total control of your VPS: change any file, install server-wide applications, and fully customize your server to the needs of your project. The Plesk Onyx management software also enables you to control your server conveniently and securely.
The bottom line is that while there are differences between these two types of virtual private servers that you should look carefully at, most people will be happy with a managed server – even with the slightly higher cost. Unless you have plenty of free time and a lot of technical knowledge, you are probably going to find working with an unmanaged server quite frustrating. A managed server might cost a little more, but it saves you plenty of wasted time, maintains better security for your site and gives you all of the control you need.

You can easily customize the network configuration for your Amazon VPC. For example, you can create a public-facing subnet for your web servers that has access to the Internet, and place your backend systems such as databases or application servers in a private-facing subnet with no Internet access. You can leverage multiple layers of security, including security groups and network access control lists, to help control access to Amazon EC2 instances in each subnet.
