In this article we will compare Shared Hosting and Virtual Private Server from different aspects.

1- Resource Allocations

Share hosting means share servers and all its resources including bandwidth, storage …, with multiple sites, whereas, dedicated hosting means you own a physical server and have full control over it. A VPS hosting operates like several, separate servers on a same physical server. In fact, VPS hosting imitates a dedicated server for users, on a share hosting environment.Shared Hosting:You will encounter restrictions, when you share server resources with other websites. On a shared hosting, using some resources such as bandwidth and storage are controllable for hosted websites, thus, these resources will be assigned to a specific amount to each user. Each website will not be able to use such resources beyond the maximum allowed.However, the use of some resources such as CPU and RAM is not controllable either. It means, the more websites use uncontrollable shared resources, the more likely you have less chance to use resources.VPS Hosting:With VPS hosting, each user has an isolated disk space and accessible environment on the server.In the other words, resource allocation cab be more exclusive, but not exactly like a dedicated server.

2- Performance:

The more resources available, the more performance will be. The performance of a shared hosting is highly dependent on the technologies that are implemented on the host to boost the speed, such as SSDs, caching software, a CDN. With a VPS you will have more control over the performance.Shared hosting:Absolutely, shared hosting for small sites with small volumes of visitors and limited performance demands is great. But be aware of sudden increase in a site’s popularity and traffic, because they will affect performance.VPS Hosting:Basically, VPS hosting offers better overall performance and has better traffic handle, based on the bandwidth provided to users. Compared with Shared hosting, VPS hosting will be the better option when you need high traffic.

3- Security:

Security issue really depends on the hosting providers. If they have invested in ensuring dedicated protection for their shared hosting customers, in that case we can say that Shared hosting is very safe.On the other hands, despite of providers investigations around their security, it cannot be guaranteed yet. Lack of security concerns to the other sites you share a server with. If a site has a security hole, then all sites on that server is affected and vulnerable. VPS hosting is more secure because of its isolated environment.Shared Hosting:Because of a common server, there will be the problem of having your hosting neighbors pull down your website. The existence of a security crash in one of the shared server customers, can impacts all customers on that shared server. Sharing space on the same server cannot guarantee security fully.VPS Hosting:A VPS avoids Noisy Neighbor problem and support more security rather than Shared hosting. Your site will have more strong security, which is only possible through VPS hosting. We highly recommend you to move to a VPS, if your business requires to protect personal data.PriceSimply, shared hosting means shared costs. You can pay as little as possible to host your website on a shared server. In general, a shared hosting is cheaper than a VPS hosting.Shared hostingSince you share server space with a large number of websites, you take related costs associated with running and maintaining a server. So economically, the shared server will be an appropriate and efficient option for you.VPS hostingFrom a cost point of view, although a shared hosting compared to a VPS hosting is more profitable, but to improve your site’s efficiency and provide more extensive online services, VPS hosting is still a better option.

5- Server Administration

Shared hosting set up anything for you, so it is much more flexible. While, VPS hosting is a little complex and server management is up to you (Usually used by developers and people with higher expertise), unless you choose to use managed VPS that handles everything such as bug fixes, server monitoring, security patches… for you.Shared hostingWith a shared hosting you do not need to know much more about server technical settings. Basic server management knowledge is enough to manage your website on a shared hosting.VPS hostingYou are responsible to configure and setup everything on VPS. Websites hosted on VPS usually need a system administrator to maintain the server. With VPS hosting, you are able to customize and configure applications and software to enhance security and performance.
  1. Scalability

Depending on how your website grows, you can choose between shared hosting or VPS hosting.Shared hosting meets your demands when the visitors of website do not exceed a few hundred per week. In such a situation, you don’t need to plan on scaling up. The problem starts when the number of your website visitors grows to the thousands. Then you might start receiving internal error messages from your host. Now to handle traffic, you will need to consider VPS or other plans.Shared hostingAlthough shared hosting is a great choice for small websites, but as your online business grows you might face scalability issues such as website crashing.VPS hostingTo get better performance having a large scale of website with high traffic, you may have to be transferred to a VPS. Anyway, shared space with multiple websites using shared resources reduces scalability factor.
