Similarly, in a real dedicated server, you will pay for the entire server that is not shared with anyone else. You will get complete control over all services. Unfortunately, it is also the most expensive hosting option and needs some technical expertise to manage. It is commonly used by those who have websites with specific scenarios, most commonly extremely high traffic and tight security requirements.
Use Virtual Network to build your services that rely on Azure cloud services and Azure Virtual Machines. Use Azure web roles for your front end and virtual machines for backend databases. Combine platform as a service (PaaS) and infrastructure as a service (IaaS) in a virtual network to get more flexibility and scalability when you’re building apps.
The web and server hosting world is full of abbreviations that look as though they were designed to confuse inexperienced hosting clients: IaaS, PaaS, SSD, SSL, VPN, VPS, and many more. It’s especially confusing when abbreviations are similar, but mean completely different things, as is the case with VPN and VPS. I’ve often heard hosting clients say VPN when they mean VPS, and vice versa.
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.
Unmetered hosting is generally offered with no limit on the amount of data-transferred on a fixed bandwidth line. Usually, unmetered hosting is offered with 10 Mbit/s, 100 Mbit/s or 1000 Mbit/s (with some as high as 10Gbit/s). This means that the customer is theoretically able to use ~3 TB on 10 Mbit/s or up to ~300 TB on a 1000 Mbit/s line per month, although in practice the values will be significantly less. In a virtual private server, this will be shared bandwidth and a fair usage policy should be involved. Unlimited hosting is also commonly marketed but generally limited by acceptable usage policies and terms of service. Offers of unlimited disk space and bandwidth are always false due to cost, carrier capacities and technological boundaries.
