A Cloud VPS is an emulation of a computer, also known as a virtual private server, that lives within a parent server and shares resources with other virtual servers. A Dedicated Server is a stand-alone, physical server that does not share resources. As with fixed resources, scarcity can lead to less than optimal performance for the resource-intensive application, which is why Dedicated Servers often outperform VPS instances.
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.
All the features I've detailed to this point are valuable to the web hosting experience, but none matches the critical importance of site uptime. If your site is down, clients or customers will be unable to find you or access your products or services. It doesn't matter how great the features are, or how good it looks; if your site is down, it might as well not exist.
Should you need more speed and performance you can also consider switching to an ssd-powered VPS package which has the same advantages as a VPS but offers faster performance due to the presence of SSD hard drives. VPS SSD is highly recommended for websites that use a lot of disk caching, for example WordPress websites with the w3 Total Cache plugin
Choose our optional all-SSD storage arrays backing our VPC. Our Premium SSD storage is 25x faster than standard storage. Solid State Drives (SSD) are ideal for high performance, transactional databases or I/O intensive workloads. SSD storage arrays also provide 256-bit data at-rest encryption, making it optimal for security and compliance based workloads.
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.
Most people are clueless about the virtual servers hosting and how they actually work on the shared environment. It is a known fact that thousand and more number of users tend to use a server at a time. In such circumstances, each user is allocated with a designated amount of disk space, bandwidth, CPU allocation, memory and Operating System, which can be used on the server. All the Virtual Private Server users share the same CPU and RAM and think that, they have dedicated set of hardware. Virtual Server software is loaded onto the physical system and from then, a virtual server is ready to be used.
Amazon Virtual Private Cloud (Amazon VPC) lets you provision a logically isolated section of the AWS Cloud where you can launch AWS resources in a virtual network that you define. You have complete control over your virtual networking environment, including selection of your own IP address range, creation of subnets, and configuration of route tables and network gateways. You can use both IPv4 and IPv6 in your VPC for secure and easy access to resources and applications.
