- Free & Effortless Migration for Unlimited Websites
The force driving server virtualization is similar to that which led to the development of time-sharing and multiprogramming in the past. Although the resources are still shared, as under the time-sharing model, virtualization provides a higher level of security, dependent on the type of virtualization used, as the individual virtual servers are mostly isolated from each other and may run their own full-fledged operating system which can be independently rebooted as a virtual instance.
Each of these stack layers contain I/O routes for anonymous public network requests that must be penetration-tested by web security professionals. Users on managed plans can expect the hosting company to keep all of the web server stack software updated with security patches, while website owners under unmanaged plans will need to keep these aspects up-to-date personally.

I have used shared hosting for over 7 years before I finally decided to upgrade to a VPS server. When I was using shared hosting, I had so many problems with malware, slow loading time, brute force attacks and so many other issues. Now, my life is so much easier with VPS. What amazes me the most is the support team; they simply exceed my expectations and they are ALWAYS available to answer my questions.

When smartphones took over in the early 2000s, data usage and cellphone bills went through the roof for many families — mine included. My family’s shared data plan wasn’t perfect — some months, someone would rack up data usage and leave the rest of us strapped — but it allowed each person to pay a lot less per month than if we each had an unlimited data plan.

VPS expands to Virtual Private Server. It mimics the more-advanced dedicated server in a hosting condition that’s mutual. VPS server management offers the features and benefits of both dedicated and shared hosting. It is best recommended for organizations that are growing at a rapid pace and might require administrative and management capabilities of an improved scale to match their pace of growth.In a VPS hosting system, there will be other websites hosted on the same physical system. However, your website’s performance or security will not be affected as it will be hosted exclusively in the allocated virtual compartment. Also, the server resources like CPU, disk space, and RAM will be available independently for your operational needs. In other words, the presence of other websites on the VPS system will not affect the performance of your website in any way. You will have exclusive access to the resources you have paid for.In VPS server management, you will also get complete root access to your server in a manner similar to users of dedicated servers. The only technical difference is that your website is on the same physical machine which has a fixed amount of resources.VPS server management gives users absolute and independent control over server operations while providing nearly the same benefits of the more expensive dedicated server. By using the services of a reputed and established VPS server management service you can enjoy high quality hardware allocations and superior network connections. At the same time, they will also ensure that your security, safety confidentiality concerns are taken care of more than adequately.The best service providers in VPS server hosting are capable of providing high quality features like fast setup and deployment, high scalability, independent reboot and shutdown without affecting other websites on the server and the ability to install any application that you might deem necessary for your business.
Essentially, here’s the criteria I would use to judge things – if your site is made up of primarily static, HTML-based content, then you probably don’t need a VPS package.  However, if you have a large amount of files stored, multiple sites, dynamic content, and the possibility of major traffic from time to time, then you might consider upgrading to a VPS. It’s a powerful package that allows you to do more than you could with a shared hosting plan, but requires less investment than a dedicated server.

VPS, on the other hand, is an isolated playground specifically for you. You will be able to install and use any professional software you need. It also provides more opportunities for caching the content. Imagine that you implement caching tools to provide your users with better experience and reduce the loading time of your website. Caching means that the part of requests to your website will be processed using RAM instead of a hard drive. Eventually, RAM will be filled with these requests. Since VPS deals offer more RAM then shared packages, you will get better performance using caching.
A VPS ( Virtual Private Server ) is a shared server platform that mimics all features and functions of a Dedicated server. A VPS will have it’s own operating system and customers will get access with full administrative privileges. This means you can install anything upon it and customize to how you see fit. It is much more affordable and economical than a dedicated server. The whole process of provisioning, upgrading, and downgrading a VPS is quicker compared to a dedicated server. Most of the process are automated and can be managed from my.interserver.net

If you are just starting your website and don’t receive very much traffic, then shared hosting is the ideal solution. However, if your website’s audience is consistently growing, you’ll want to consider upgrading. You don’t want to run the risk of your website running slowly or, even worse, your server crashing because it can’t handle the traffic. If you anticipate an increase in visitors, do yourself a favor and switch to VPS.
What are the benefits of VPS hosting? VPS hosting is great for hosting many web sites in an environment where you have almost complete control while still keeping your costs down. You can install a custom Apache module or try out a new programming language. You can get in a and make detailed changes using the command line or remote desktop but your hosting company still usually makes it easy to administer your site using a Virtualization control panel such as Virtuozzo Power Panel.
However, if a bad user shares your server with you, they can threaten your security and allow hackers to easily reach your content and critical data. Furthermore, because you’re all sharing the same resources, if any of the users that you’re sharing your server with use a lot of memory or their site has a lot of traffic, your website’s performance is likely to suffer.

A great advantage of VPS, compared to both shared and dedicated solutions is snapshot technology support. A snapshot is a state of a system at a certain point in time. It works like game saves in your favorite computer game. If a game is not going well, you can exit and start from a checkpoint. A snapshot works the same way; if you need to go back in time, your system can be restored from a snapshot to its previous state. It is extremely useful in case of a system failure or simply if you run complex tests and wish to save your progress. Unlike a backup option that copies the whole system each time you run it, a snapshot contains only changes. This means that a snapshot takes less space than a backup and can be created/restored quicker. It does not mean that you do not need backups though. Backups are still life-savers in case of operating system failure. Don’t forget to store them externally.

Nice read Rahul ! While you compare all hosting types, I would like to point out one important thing related to shared hosting. Undoubtedly, VPS hosting has become the most popular hosting type in short span, but shared hosting has its own benefits. First and most important one is – Shared Hosting is by Default Fully Managed, that means you don’t have to worry about security of your website, server updates, software update, spamming from your mailboxes, etc.


The answer to this question is a definitive “maybe.” Since you’re looking at this site, you might be a Web designer who has a few sites, an online portfolio, and a couple of long-standing clients whose sites you manage. Is a VPS for you? Well, you’ve most likely outgrown a shared platform, and as a professional, it won’t do to have your site run poorly because another site that you share a server with is using more than its fair share of resources. A dedicated server could be overkill – if you don’t need all the resources on a consistent basis, you may not be able to justify the expense.
As you can see, a VPS can be the perfect middle ground for many – enough flexibility and resources for those who need more access or control than on a shared server but without the cost of a dedicated server. If you need root access, you can’t get that on a shared server, but you can get it on a VPS. If your site experiences unpredictable swings memory usage, and your host provides it, then the presence of burstable memory will be attractive. And, if you’re a fan of customization, then the fact that you can customize server-level software such as PHP, MySQL, and Apache will perk your interest.  In short, choosing a VPS will allow you to have many of the same characteristics of a dedicated server but in a more affordable and manageable package.
"Root" gives you administrative level access to edit, install and configure all of the files on your server, including system-critical files. It gives you ultimate access to your server. This gives you the ability to configure your server to your exact needs. While root access gives you full control of your server, it is intended for experienced users, engineers and developers. That's because you do have the potential to misconfigure or delete those system critial files if you're unfamiliar or inexperienced with what you're doing.
It comes down to basic reasons: If your business is growing and receiving more traffic, it is time to move to a more controlled setting like VPS.
Similarly, in the case of VPS, there are several users that are using the same server but they are isolated from each other. It means that no one will be affected by how much resources another is using. You will get the speed and security that you need without compromise. It is almost a perfect scenario because you will get the benefits of a private server with shared cost of services.

I can’t say it as a disadvantage of VPS hosting because many of our VPS hosting customers have server administrator to manage their VPS and they manage it in very efficiently manner. But this doesn’t everyone must have server administrator, we have content-rich knowledge base on VPS hosting for our self-managed customers.Also, a managed service option at very affordable price.
