To make a website visible online, its files need to be uploaded to a web server. You can purchase this server from a hosting provider. This service is called web hosting. Most website owners start their work by shared web hosting. When their site grows and requests more resources they may need a powerful hosting server. A virtual private server (VPS) is generally considered as more powerful between shared hosting and dedicated hosting setup in which your website works on its own server.
VPS hosting:
VPS is the abbreviation of a Virtual Private Server. It is one of the most popular hosting services you can select for your website. It works with virtualization technology to provide you with dedicated (private) resources with multiple users on a server.
VPS hosting is a more secure and stable solution than shared hosting. In shared hosting, you don’t get a dedicated server space. However, it’s smaller-scale and less expensive than acquiring an entire server.
VPS hosting is often used by website owners who have medium-level traffic that exceeds the limits of shared hosting plans. VPS solutions usually provide more than one hosting plan.
How does VPS work?
A server is a computer on which your web host adds the files and databases essential for your website. Whenever an online visitor wants to reach your website, their browser sends a request to your server. And it moves the important files through the internet. VPS hosting gives you a virtual server that reproduces a physical server. However, in reality, the machine is shared among many users.
Your hosting provider installs a virtual layer using virtualization technology on top of the operating system (OS) of the server. This layer breaks the server into partitions and allows each user to add their own OS and software.
Therefore, a virtual private server (VPS) works as both virtual and private because you have complete control. It is different from other server users on the OS level. In fact, VPS technology is just like creating partitions on your own computer when you want to work with more than one OS (e.g. Windows VPS and Linux) without a reboot. If you have VPS hosting, you will acquire the same root-level as if you had a dedicated server, but it will cost you much lower.
Containers:
Containers are a type of operating system virtualization. A single container might be useful to operate anything from a small micro service or software process to a larger application. A container contains are all the essential executables, binary code, libraries, and configuration files. Containers do not contain operating system images Compared to machine virtualization approaches. This makes them more lightweight and portable, with small overhead. In larger applications, multiple containers may be deployed as one or more container clusters.
Containers provide a logical packaging mechanism. In this mechanism, applications can be absorbed from the environment in which they actually work. This decoupling helps container-based applications to be deployed easily and consistently, regardless of whether the target environment is a private data center or even a developer’s personal laptop.
