Different Types of Web Hosting

• Shared, VPS, Dedicated and Cloud hosting
  explained
• All websites and blogs on the Internet start with
  hosting. A Host is a type of computer on which
  webpages are stored for retrieval.
• A lot of people get confused about the different
  types of web hosting that we have out there. In
  this article Ill clear up the differences
  between the most common hosting types Shared,
  VPS, Dedicated and Cloud, lets get started.

But, what is Web Hosting?

• First, lets clear up what hosting is in the
  first place. When you view a website in a
  browser, you are actually receiving code written
  in a bunch of different coding languages Hosted
  or stored on a Web Server.
• Your browser converts this code into something we
  can actually understand images, buttons, text
  columns, and so on.
• But, what is a Web Server? A Web Server is
  essentially a computer that holds a bunch of
  files and is capable of performing operations on
  them. It has a CPU, it has memory, it has a hard
  drive, and other components. It even has an
  operating system, usually a Linux-based one.
• So where does hosting come in, whats the
  difference between a host and a server? Your host
  is the company that owns the server your content
  is on. In addition to giving you the hardware for
  your website a host usually offers a bunch of
  other services like server management, support,
  malware scanning, and backups and so on.
•  
• In simple words a hosting provider is a company
  that sells server space and related services.

Theres different types of web hosting

• There are three basic ways to differentiate
  between hosting packages. One way is to look at
  the technology used for the server.
• This is what gives us our four categories
  Shared, VPS, Dedicated and Cloud.
• The second way is to look at the level of
  management offered. Most hosts offer server
  management, but you can buy servers where you
  need to do all of this work. A managed server
  means less work for you but also less
  flexibility, an unmanaged server means more work
  but more flexibility. There are packages that
  offer some management services so
  unmanaged/managed is only the two extremes, there
  is a spectrum of services in between.
• The third way is to look at the additional
  services on offer. Some additional services would
  be backups, level of support, malware scanning
  and cleaning, SSL certificates, free CDN
  bandwidth, platform specific services (e.g.
  WordPress), staging site creation, etc.
• In this article were focusing on the first way,
  looking at the technology used on the server.
  Lets explore them each in detail.

Shared Hosting  Cheapest, Best for Beginners

• Shared hosting is the budget option. It is
  extremely cheap, but also not very good let me
  explain how it works.
• Remember how a server is a computer with
  resources like hard drive space, CPU speed and
  RAM? In a shared hosting environment the host
  puts a large number of users on a single server.
  By large number I mean that it can be over 1,000
  users. Each user may have a number of sites so
  that one single server houses somewhere around
  3,000 sites.
• The problem is that these websites all share the
  servers resources. If one website has some
  faulty code or simply gets a lot of visitors it
  could use 75 of a servers memory for example,
  which means that the other 2,999 sites are left
  with 25 of the total RAM.
• Needless to say, this leads to websites going
  down or loading slowly for people who have
  nothing to do with the site the issue originated
  at. Even worse these issues are completely
  unpredictable from the point of view of those
  2,999 sites.
• This is called the bad neighbor effect and is
  one of the main reasons shared hosting is not the
  best idea.
• To be fair, many hosts try and make things better
  by detecting faulty sites or sites that
  experience a high level of traffic and either
  working with the owners, or disabling the site
  temporarily. This rarely works in the long run.
  Its not the hosts fault, its simply a
  Sisyphean struggle.
• In addition do the math. If each customer is
  paying 5 per month, is it really worth spending
  hours of support on a single customer? Not
  really.
• So is shared hosting ever a good idea? Yes! It
  can be great for housing development sites, test
  sites or websites where uptime is not a huge
  bother. You could have a personal diary or a
  website created for your family. It may go down a
  few times a month, but that shouldnt be a
  problem.
• Shared hosting is also a great option if you are
  on a very tight budget. Shared hosting allows
  businesses to create a web presence in countries
  where it would otherwise be impossible. As such
  shared hosting is an extremely important tool for
  equality on the web.

VPS Hosting  More powerful than Shared hosting

• VPS stands for Virtual Private Server and is
  probably the most popular service to upgrade to
  and it can be the most well-balanced one as well.
• A VPS server is still a shared environment, but
  the way it is shared is very different.
• First of all, a VPS server is usually limited
  to 10-20. This decreases stress in itself, but
  the real improvement comes in the form of the
  hypervisor which is the coolest name for
  something ever.
• A VPS server is literally split into as many
  parts as there are users. If there are 10 users,
  10GB of RAM and 200GB of hard drive space on the
  server, each user will be able expend 1GB of RAM
  and 20GB of space. Once you hit the RAM limit
  your site may go down, but the others will remain
  stable. The hypervisor is the one responsible for
  managing the virtual machines that create this
  separation within the server.
• This simple addition removes almost all of the
  bad neighbor effect. Extremely rarely there can
  be some issues which affect multiple users by
  affecting the hypervisor itself, but this isnt
  something you need to worry about.
• Another big benefit of VPS servers is that they
  are highly configurable, providing a lot more
  flexibility. On shared hosts you cant really
  modify your environment because youd be changing
  everyone elses as well. Since your account is
  contained within a virtual machine you can make a
  lot more changes without affecting others. This
  is something developers will be happy about.
• Lastly, VPS is scalable. Since you are running a
  virtual machine which takes some percentage of
  the resources available to the server as a whole,
  the amount of resources you are allowed to use
  can be increased in seconds. This is a great
  comfort to business owners who expect their sites
  to grow and flourish.
• So, who is VPS for? I would actually recommend
  VPS services to anybody who has around 20/month
  to spend. VPS can get a lot more expensive, but
  even the lowest tier will be a lot better than
  any shared hosting solution.
• VPS packages can come as low as 10/month but
  most of them would clock in at around 25 with
  the average service being 50 a month. As you
  scale up you can get into the 120 150 range
  but dont worry too much, if you actually need
  that much RAM and bandwidth you are probably
  making enough money to easily cover the cost.
• A little addition here at the end A high end VPS
  can be a lot cheaper than a low end dedicated
  server and also a lot more powerful. Dont be
  fooled into thinking that dedicated is a more
  advanced option just because you are the only
  person on a server. Look at the resources
  available to you instead, thats what really
  matters.

Dedicated Hosting If Your Site Exceeds 100k
Visits/month

•  
• This is the hosting service that negates all bad
  neighbor issues because you are all alone on a
  server. This provides a host of benefits, but
  also comes with quite a few downsides.
• Since you get a computer all on your own, many
  companies allow you to customize it extensively.
  You may be able to choose the amount and type of
  memory, the OS to install, and other hardware
  elements that make up a computer. This gives you
  a lot of flexibility which may be needed for some
  specialized software.
• The downside here is that you actually need to
  know quite a bit about computers and server
  technology. While there are managed dedicated
  hosting solutions youll still need to do a lot
  more on your own.
• On the extreme side of things, you could get a
  completely unmanaged service where you would even
  need to install the OS yourself, let alone all
  the tools needed to run a web server, security
  scanning, malware removal and so on. I wouldnt
  actually call this a downside, but its something
  you need to be aware of when shopping for a
  server. If you want to go dedicated youll need a
  server admin, or sufficient knowledge to do it
  yourself.
• With great flexibility comes great control. You
  can potentially run a lot more applications in a
  more streamlined fashion. You can run a bunch of
  tools that serve only one purpose making
  your website faster.
• Being alone on one server comes with another
  downside hardware failure. With a cloud VPS if
  RAM fails in the system, other memory modules
  simply take over. With VPS if something fails,
  another memory module might take over, or the
  module will be replaced automatically pretty
  quickly. With dedicated servers you might need to
  wait a lot more, especially if all the server
  monitoring is up to you.
• When would someone need dedicated hosting? In
  todays World with cloud VPS catching on I would
  maybe even discount large sites needing dedicated
  hosting. Dedicated can take a lot more hits than
  traditional VPS, but nowhere near anything a
  cloud based system could scale to.
• The only two times I would say you definitely
  need a dedicated server is if you have highly
  specialized needs in terms of hardware, or you
  want a lot more control over your datas privacy
  than anywhere else. A dedicated server
  compartmentalizes you which can be a bad thing,
  but from a security point of view its great.

Cloud Hosting

• Cloud hosting is essentially the same as VPS
  hosting. Some companies dont even call their
  service VPS anymore, the say Cloud or Cloud VPS.
  Lets look at what cloud computing is first, and
  get back to what this has to do with hosting.
• Until now weve been talking about computing that
  is similar to buying unit based products. If I
  buy a one-use battery and put it in video camera
  I can use it for a set amount of time until the
  battery runs out.
• Cloud based computing is similar to how utilities
  work. If I plug my video camera into the mains I
  can use it as much as I need and it will take as
  much power as it requires at the moment. If it is
  on standby it will use very little power, when it
  is recording it will use a lot more but the
  electric system can handle the changes in power
  requirements.
• Cloud based hosting allows you to use the
  resources of multiple servers in a network. This
  makes it even more scalable, in addition to
  providing a host of additional benefits, mainly
  based around security.
• A traditional VPS can be scaled, but only to a
  certain point the maximum capacity of the
  hardware it is on. A cloud based system can be
  scaled a lot further.
• Cloud based systems also have a much higher
  chance of protecting you against DDoS attacks.
  DDoS attacks are not a security risk, their only
  purpose is to overwhelm your website with
  requests, causing the server to crash. Currently
  the best method of protecting against such an
  attack is to block as many requests as possible
  and spread the rest within a large network. With
  cloud systems the network is right there, if it
  is large enough it could withstand an attack much
  better than any single-server system
