Shared Hosting 
 
Pros

The biggest advantage of this option is that you also share the cost of server with many people. If the hosting provider can put several hundred or thousand clients all on one server, it allows them to spread the operating cost among many parties.

That’s also why shared hosting is the most affordable. You can have it for as cheap as $2/month with the average cost in the $5-$10/month range. Great for people with limited funds and those just starting out.

Aside from that, with a shared hosting account you are usually completely taken care of in terms of setup. There is very little to configure so you can concentrate completely on building your website. 
2. VPS Hosting
 
Pros

VPS is a lot more reliable and stable than shared hosting. First of all, is usually limited to 10-20 websites per server. This decreases the demand on the server in itself.

However, the real improvement is that all resources are split evenly and no website is allowed to exceed its lot. Once you hit the limit of what is assigned to you, your site may go down but the others will remain stable.

This is achieved via virtual machines that create a separation within the server. This simple addition mitigates most of the bad neighbor effect.

Another big benefit of VPS servers is that they provide more flexibility and allow you to customize your environment. On shared hosts this isn’t possible because it would change everyone else’s setup as well. Since your account is contained within a virtual machine you can make changes without affecting others.

Lastly, VPS is scalable. Since you are running a virtual machine which takes some percentage of the resources available on the server, increasing what is available to you is no problem at all. This is a great comfort to business owners who expect their sites to grow and flourish.

 A proxy server is a dedicated computer or a software system running on a computer that acts as an intermediary between an endpoint device, such as a computer, and another server from which a user or client is requesting a service. The proxy server may exist in the same machine as a firewall server or it may be on a separate server, which forwards requests through the firewall.

In the enterprise, a proxy server is used to facilitate security, administrative control or caching services, among other purposes. In a personal computing context, proxy servers are used to enable user privacyand anonymous surfing. Proxy servers can also be used for the opposite purpose: To monitor traffic and undermine user privacy.
Load balancing refers to efficiently distributing incoming network traffic across a group of backendservers, also known as a server farm or server pool. ]]> 2019-03-18 10:06:39 UTC https://padlet.com/obedelamo/g58iff9bk85j/wish/342307355 Servers. obedelamo https://padlet.com/obedelamo/g58iff9bk85j/wish/342307400 What is a server?  What Is the Purpose of a Computer Server? A server is a computer used in a network and which provides a service to a client. Servers usually have more processing power, memory and storage than client computers. 
Differences:

  • Servers are designed to run 24/7 even in the case of failures. They have redundand components - two power supplies, pairs of disks, double network cards etc. You can replace components while the server is in operation.
  • Servers have better cooling - lots of fans which can run pretty loud if aggravated.
  • Servers usually have better quality components than consumer hardware, which is why they are more expensive.
  • Servers support plugging more memory, CPUs and disks than ordinary computers.
  • Servers don’t need graphics or sound and usually don’t have it. On the other hand, graphics and sound is very important for PCs and laptops.
