In a shared hosting plan, hundreds of websites lie on a single physical server. All these sites share a common server resource and thus has a lot of interdependencies. Whereas, a VPS hosting works on the lines of virtualization where each website lies on a separate virtual machine (VM)
A domain and a website are closely related. A domain is a string of text that is essentially required to identify a resource or website on the internet. In short, a domain name is the address of the website. Whereas, a website is a group of web pages that are hosted on the internet somewhere on a web server.
Shared hosting utilizes a single physical server to host hundreds of websites. But cloud hosting uses the concept of virtualization where each virtual machine hosts a single webpage. Shared is the cheapest available plan, whereas cloud hosting is a bit pricey.
Cloud server hosting uses the concept of virtualization (VM) with an underlying network of bare metal enterprise server machines. Whereas, dedicated server hosting involves a physical server to host a single website or application. A dedicated server will cost you more money than cloud hosting.
There is a vast difference between VPS and cloud server hosting. Cloud hosting is premium service which offers greater scalability, reliability, security, performance, etc. than VPS hosting. VPS hosting involves one physical server whereas cloud hosting is based on network of several web servers
Superficially, the noticeable difference between shared and dedicated server is the cost. But there are underlying major differentiating factors such as performance, disk space, bandwidth, security, uptime, etc. Dedicated server hosting is suitable for large businesses
