Between these two options is virtual private server or VPS. VPS is cheaper (much less) than a dedicated or private server, and offers more freedom and more opportunities to a growing online business than shared hosting. With a Virtual Private Server receives any web hosting account its own operating system. Users can these components without affecting other users on the same physical machine because they work within their own virtual server. In addition, a VPS hosting environment can be readily scaled to more vigorous physical hosts as demand rises. In the long term, VPS hosting to a reduction in the total cost of ownership.
VPS is not suitable for every site owner. Some people want a low to moderate traffic website host and were satisfied with the degree of control that a web hosting control panel like cPanel or Plesk. These people will prefer Shared Hosting for its perceived simplicity and ease of use: they are generally no Linux system administration experience and are not interested in picking up something. Others are developed from their shared hosting account or are not happy with site performance (30-second download times) it is definitely time to move to a VPS account. A good web hosting company can help you migrate from your shared account to a VPS account with no crashes or problems.
VPS should I? If you are planning to expand, offering more products and services, then consider a VPS plan, even as a start-up. The difference in price between a good shared hosting plan and a good VPS plan is negligible in the whole blow-buck equation.
These are the main advantages:
PERFORMANCE
Shared server accounts are always dependent on the performance and good behavior in neighboring accounts. If one account violates their terms of service and sends a mass-mailing of spam, it will load on the server and a negative impact on the performance of all accounts on that server.
VPS are guaranteed funds. A customer cannot run away with a large share of resources. To implement reliable and predictable service. If you're a bad neighbor VPS, they often affect only their own accounts, each account will appear as a separate server on the Internet. They will not be able to get your memory when you need it, get your server blacklisted, etc.
High customizability
Virtual Private Servers are feature rich. They are functionally equivalent to a dedicated server. Some programs require that certain ports and / or protocols be opened or closed in the firewall. With shared hosting, custom firewall configurations are not recommended for security reasons. In VPS, custom firewall configurations, due to a breakdown of clients.
With a VPS, you can close ports using iptables function.
You have your own IP address.
You have root access.
Freedom to reboot your VPS at any time.
You can also personalize services such as web, mail, database, panels, domains and much more ...
The only restriction is that you are unable to install your own kernel. This is due to the nature of how a VPS work.
SAFETY
Shared hosting is inherently difficult to achieve complete. If an account on a shared server is broken, the criminal damage to the entire server, which prolonged outage. If a spammer gets the server to get blacklisted with Spam organizations, this effect on other accounts that produce legitimate mailings until the server to the whitelist.
VPS accounts are insulated from each other, to minimize the risk of unauthorized access by hackers and other customers. Isolation of your account also reduces the risk of being hit by a DoS attack that was intended for another.
Scalability
Virtual private servers are inherently scalable - whether you are a minimal allocation to run a simple e-mail server or virtual private network end-point or a webserver with enough resources to an extensive database applications and support heavy traffic, there is always a VPS hosting plan for your needs. Additionally, you can at any time simply downgrade or upgrade your service with little or no downtime!
UNLIMITED SITES
Another advantage of VPS is the ability to handle many sites. You do not run into problems with hardware components, even if you performed a dozen different places. Your access to server assets is assured through the use of server-side software such as Apache Virtual Hosts and VPS packages similar. VPS hosting plans are a bit more expensive than shared hosting. But with more and more sites come on line (about 6,000 per day!) VPS offers better value for your dollar server if you host as many sites as you want. When considering VPS plans, the monthly cost of amortization of the number of sites you expect to create. You will quickly see that VPS monthly costs are consistently lower than shared hosting on a per-site basis.
There is one small disadvantage of VPS for some people. VPS = more responsibility. This means that you are responsible for much of the software installations, maintenance, site security and many other tasks that come with online purchase. If you do not know much about server side administration may VPS a bit more than you want to take for yourself. It is something to look forward to a farm expert if you're unfamiliar with the continuation of a VPS, but you still need power and control of the VPS.
The solution - get a managed VPS provider will take care of things for you, and you can fully focus on the content of your website.
