Internet, as most people know, it consists of many web sites that hold information and serve it to other people (visitors). Either a sales management system hidden from plain sight and running in the background of a server and point of sale devices or be something like Facebook, which is actively accessed and data being uploaded. They share the same basic principle: They all run on high-performance computers, which has uninterrupted uptime and has the sole purpose of serving data. Yes, we are talking about servers and hosting.
The free option
Hosting is your “real estate” connected to the internet all the time with nearly 100% uptime in a given timeframe. You can buy it or rent it; you may also enlarge and shrink it to fit your needs. In terms of free hosting is neither free nor it is hosting in common sense. Most of the free options can be scaled up, but some can fit your demands. That means you will not have to pay for anything while your website is being hosted.
The free option has limitations most of the time. An example of this is Blogger “hosting” your website (or rather your blog) with a limited media upload capacity. But you do not get to choose everything that makes up your site; you have limited options with this free blog hosting. You can find many free hosting services for your needs.
Shared hosting is the most common option for basic web hosting. By basic we mean it is accessible by the most people at reduced rates, not as scalable compared to other solutions but quite capable of running many modern server components – like PHP, MySQL, PostgreSQL, etc.
All content management systems can be installed by one click, like your own-hosted copy of WordPress. They are also quite manageable by any tech-savvy person through the interface provided. The hosting company provides basic security, and the rest is on your shoulders for keeping the content management system you use up to date.
This is the place where things get pro-level techy. In VPS hosting, you will have a VPS (Virtual Private Server) system, which means a virtual GNU / Linux box with a console interface to manage the whole system. You will have some storage, at least one network interface, and a few virtual CPU cores.
You will oversee every aspect of the virtual system. If you have an unpatched web server, you might get hacked, as well. These systems may be scaled a little bit by adding more virtual CPU cores (vCPU), network interfaces, and storage, but that is all. You will be limited by the hypervisor performance and underlying bare metal system.
Dedicated servers are like shared hosting options; the difference is that you are alone in the server. You can use all the resources of one physical machine and generally use a GUI management tool to execute tasks on the server like backup and installation of server components.
You may also get something close to the bare metal and manage it through the console with little software management overhead, but then you will get close to a colocation service that you may love to opt in to. If you are good at setting up and managing a server, this option might be for you.
Colocation is generally involved buying or renting the server already placed in a rack but not yet powered on. You may get to customize the specs up to a point, but not everything. In most cases, you’ll be offered some options to pick from.
Then you will be paying for the electricity and internet connection, but they are included in the package if you are renting rather than buying the machine. At the end of its duty, you may have the server physically shipped to you. You manage everything, and hosting providers might provide you with an on-demand KVM to remote management.
Your own infrastructure
This is for people who will bring their server to the datacentre, hiring the space and paying for the electricity and internet connection. You manage everything; you will have to backup manually, repair the system if something is physically damaged. You will also place hardware firewalls of your own and load balancers if you have a cluster. You may even run your OpenStack bunch with servers located on different regions if you have the money and will to do so.
You will need a system administrator – or an army of them in the OpenStack – case to run the system if you are not the one. On the other hand, you can optimize the system you can do obscenely detailed customizations and optimizations. That is a huge benefit. You may physically access the system or systems but generally with prior appointment. You might request KVM to access if the server is down if you did not hire a private datacentre cage.
Cloud is the most versatile option today, expanding and shrinking at will. Adding and removing services, servers, and many different abilities are done in the blink of an eye. Not only versatile but also a cost-efficient way to host anything, the cloud has the security, scalability, and performance best in the world. You may also like to have, for example, only data storage without dealing with other aspects of building a server for it.
Maybe you just want to have a database hosting on the cloud. A place that all your endpoint devices read and write to, regardless of their type. Managing cloud hosting is easier, and things happen faster. You think that it is unlikely to a disaster hit your systems so that many people do before something breaks down, and they moan of agony and despair. Cloud options provide you with the utmost security, while disaster recovery is quite fast compared to all other options.
