Amazon EC2 is a web service that provides secure, resizable compute capacity in the cloud. It is designed to make web-scale cloud computing easier for developers. You can use Amazon EC2 for a variety of applications, including websites and web applications, development and test environments, and even back-up and recovery scenarios. Amazon EC2 offers a wide selection of instance types with varying combinations of CPU, memory, storage, and networking capacity that you can use to meet the unique needs of your applications.
Reduces cost – It is a known fact that, all virtual servers run with 90 percent of utilization versus the servers which are non-virtualized, which only achieve 18 percent utilization ability. So, when the utilization increases, it offers justification to the power consumed and also to the deployed cooling solutions. Thus from the above benefits, an enterprise can save, from their operational costs.
Virtual servers are scalable and come with dedicated core and memory allocations. They are a great option if you are looking for compute resources, that can be added in minutes, with access to features like image templates. The hypervisor is fully managed by IBM Cloud, and you can perform configuration and management tasks by using both the IBM Cloud customer portal and the API. Virtual servers are deployed to the same VLANs as physical servers, allowing you to spread workloads across virtual servers and bare metal servers while maintaining interoperability. Virtual servers are fully customizable when you 
order them, with options to scale up as your compute needs grow.
If you'd like to run a VPS, I'd suggest you to look for a managed one with cPanel. cPanel is a piece of software that facilitates a lot configuring the server, while managed means that the support guys will help you with initial configuration of the server, and also help you out with config/upgrades whenever you need help. It's a bit more expensive than non-managed, but if you don't know how to manage/administer a server, than it's essential. You can find a decent managed VPS in USA from 20 $ and up.
If you want reasonably priced server space that won't load pages at a snail's pace when a neighboring site gets a huge traffic spike, VPS is a good option for your business. We've reviewed many VPS hosting services and included the best of the bunch in this guide. You should look into a dedicated server if you want to build a website on an even stronger foundation and can afford the bill.
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]
