Web hosting is a collection of files/web pages stored on server, with a connection powerful machine enough to facilitate simultaneous access and tasks.

Web hosting is the term given to describe the software and systems in place to ensure the availability of each and every webpage, typically subsumed within the definition of ‘web hosting services and their respective providers. Naturally, it’s a huge industry.

These are the types of Web Hosting:

Shared Hosting

This is mostly used by a lot of sites around the world. It is cheap compared to the rest, consists all necessary features such as security, web apps and more. In shared Hosting, a single CPU, a single hard drive, and a single network connection is used to accommodate a number of websites, and their respective traffic.

Pros

• Inexpensive and easy to setup.
• Great for low-requirement websites (such as blogs etc.)
• Doesn’t compromise on reliability.
• Great option for those with minimal needs.

Cons

• Limited hardware capacity due to shared server.
• Inability to customize or make direct changes to the server (no root access).
• Performance potentially jeopardized by other websites.
• Added risk from shared server.

VPS Hosting

Virtual private servers sit on the line between shared hosting and dedicated hosting. VPS is expensive compared to shared hosting due to extra addons. A virtual private server is a dedicated server, but uses a virtual machine rather than a physical one. This hosting is best for experts who prefer custom modifications to their server to fulfil a specific web function or are running a SaaS (software-as-a-service) business, and premium websites that receive a lot of traffic. Most of VPS are fast compared to shared hosting. The main advantage of this versus shared servers is that it allows the user more control over the server environment with root access. In VPS, there is only single virtual to manage the website which sometime can go down if server is overloaded or other bug.

Pros

• Still more affordable than dedicated servers.
• Root access with more control over the server.
• Increased resources.
• Fewer security issues. 

Cons

• Remains susceptible to performance issues from traffic spikes in other servers.
• Lacks the substantial system resources offered by dedicated server hosting.

VDS Hosting

VDS is virtual dedicated server, more advance and semi-dedicated hosting. Unlike VPS, VDS has ability to handle large load balance because it uses semi-pure dedicated resources. VDS pricing is higher compared to VPS and Cloud hosting. If you have website that receives at least 10M per month, then VDS is the perfect hosting for you.

Pros:

• Semi-dedicated resources
• Less pricing compared to dedicated

Cons:

• Higher pricing compared to VPS

Dedicated Hosting

In dedicated package, everything is dedicated to user, no any resource shared to another customer. This hosting is very expensive due to fact that it is allocated to single customer. This is the best choice for growing and up-and-coming websites, which will require a server that can accommodate sporadic spikes in activity like social networks, banks, Telecom companies and more.. For any business, traffic spikes are naturally a great thing, and should never be stifled by hardware, software, or network bandwidth capacity limits.

Pros

• Improved performance capability and capacity (bandwidth, CPU, storage, etc.)
• Full control over the server machine. 
• Server machine can be customized as desired.
• Minimal security risks.

Cons

• Substantially higher cost over alternatives. 
• Singularly responsible for the server. 
• Potentially requires more technical knowledge.

Cloud Hosting

Cloud hosting is a form of VPS hosting that scales with the amount of traffic your website receives. Herein is cloud hosting’s main advantage – it has an unlimited capacity to handle traffic spikes, where by multiple virtual servers are connected into one and removes any possibility of bandwidth or CPU bottlenecking. Under the dedicated and shared server methods, real machines are used that have finite limits. These limits cannot suddenly shift depending on the quantity of traffic as a single computer only has a certain amount of CPU power and bandwidth to provide.

Pros

• Unlimited capacity to accommodate spikes in traffic. 
• Scalable cost – pay for what you use.
• Multiple VPS’s within a single customer account, allowing for multiple instances of a website’s development cycle to exist simultaneously. 
• Great for new or growing websites. 

Cons

• Service can vary from provider to provider. 
• Can become costly if website receives a lot of traffic. 
• Mainly suitable for those with higher-than-average needs.
