When it comes to choosing a reliable web hosting service, people are pretty much confused. There are many questions such as: Do I really need a VPS Hosting? Cloud Hosting? Why is VPS better? What is the difference between traditional shared hosting and a VPS hosting? In this article, I will explain the concepts and types of web hosting out there.
Traditional Shared or Dedicated Hosting
In a traditional shared or dedicated hosting, the hosting providers take a full control of the server and handle at least 50% of technical tasks for the users. However, with that control, they can do all kind of shady business that you do not have any clue. The hosting providers can add 50-100 users on one small single server and everyone has to share the same CPU and available amount of RAM. So whenever one of the users abuses the service, all users will suffer. The website could be laggy and unreachable if the server reached its limit. Therefore, you should avoid shared/traditional hosting at all cost unless it is cheap (like 5, 10 USD per year) and the provider has a good reputation. It does not worth to pay 50 USD per year for this kind of service. There are much better alternatives for the same price. A good rule of thumbs is that you should use shared hosting only when you have a very small website and you don’t have a lot of knowledge about managing a server.
What can you do with a traditional shared/dedicated web hosting? there are only a few things you can do with a traditional web hosting: (1) Host websites and web apps (2) Store, Share, & Transfer Files (3) Stream videos
VPS Hosting or Virtual Private Server Hosting is a popular web hosting method nowadays. VPS Hosting is based on virtualization technology. Each hosting account acts like an independent physical server with predefined specifications. All VPS on one single server share the same resources (CPU, RAM, and Disk Space) of the physical host server. Each VPS needs to have at least one dedicated IPv4 Address and/or one to many dedicated IPv6 Addresses. Within one VPS, you can create multiple websites and share the same IP Address. However, the number of websites you can host depends on how much resources you have.
In general, there are two types of virtualization for VPS Hosting such as OpenVZ virtualization and KVM virtualization. OpenVZ virtualization VPS generally gives you more resources for the price. But, it has a lot of limitations. KVM virtualization VPS is better and gives you more control. In the next article, I will explain more about these types of virtualization and how to choose the right one for your web hosting need.
What can you do with a VPS hosting? There are many things you can do with a VPS Hosting: (1) Host websites and web apps (2) Run desktop and command line apps (3) Set up VPN server (4) Store, Share, & Transfer Files (5) Stream Videos, and other purposes.
Cloud Hosting is one of the most powerful and reliable hosting types out there nowadays. Cloud hosting services provide hosting for websites on virtual servers which pull their computing resource from extensive underlying networks of physical web servers. It is very much similar to VPS hosting. But, the big difference is that cloud hosting uses resources from multiple networked servers while VPS hosting uses resources from a single server. Cloud hosting follows the utility model of computing in that it is available as a service rather than a product. You pay for what you use and when you use it.
Cloud hosting providers can offer their services under Infrastructure as a Service (IaaS) and Platform as a Service (PaaS) classifications. An IaaS provider simply offers virtualized hardware resource so that you can install your own choice of operating system and then build web applications. PaaS provider offers not only virtualized hardware resource but also a full solution stack (operating system, database, web server software, etc). The users of PaaS can then go straight to web app installation process.
What can you do with a Cloud Hosting? You can do most possible things with cloud hosting. The possibility is unlimited.
Choosing the right web hosting service is challenging. At the end of the day, it is all about the size of your application and what your need for your application. In addition, it is very easy to get a bad service. Therefore, you will need to choose a good reputation provider. The best way is to ask about it in internet forums. Also, you need to try and test the service thoroughly before you put a serious commitment on a specific provider.
