Among all types of hosting, VPS hosting is distinctive in multiple aspects. Therefore it is essential to know what is VPS hosting and how it compares with other types of traditional hosting.
What is a Virtual Private Server?
A VPS or a Virtual Private Server has its own copy of operating system and resides within a larger and physical server. Users of VPS hosting are able to access server root access and dedicated resources in an isolated environment in spite of its multi-tenant nature.
How is VPS hosting implemented
Every site is backed by a powerful hardware in VPS hosting. The large physical server is partitioned into multiple virtual servers by independently setting up server software on every virtual server. This imparts a separate existence to every virtual server and ability to function individually.
Virtual hosting is offered by allocating independent virtual compartments that entitles a private environment with independent access to server resources including disk space, RAM, and CPU. This means no other website in the same machine will be able to influence performance of your site. Users of VPS hosting have full access to all resources that are being paid for.
Complete root access to server is a distinct feature of VPS hosting that makes it equivalent to dedicated hosting. Users of VPS hosting are able to enjoy dedicated resources and isolated operations at much lower costs than dedicated hosting.
Evaluation of VPS hosting with other types of hosting
Shared hosting– The most striking distinction between VPS and shared hosting is the way resources are being shared by users. In shared hosting, users are supposed to share common resources without any independent access to server. However, VPS hosting not only allows root access to server but it also entitles dedicated resources including disk space, RAM, and CPU among others. There are fewer accounts in VPS hosting environment than shared hosting.
There are certain demerits of VPS hosting in comparison with shared hosting. The foremost disadvantage being the cost of VPS hosting is higher than shared hosting. Users of unmanaged VPS hosting are expected to be technically proficient in server management in terms of monitoring as well as maintaining the same to make sure that it is secure and is running normally.
Dedicated hosting – In dedicated hosting environment, user is offered access to a standalone server without any interference from other accounts. All resources of a physical server are reserved for a single user. This arrangement supersedes all other types of hosting including VPS hosting as far as performance, security, and server access is concerned.
VPS hosting can be considered as an intermediate hosting between shared hosting and dedicated hosting since it offers economy of multi-tenant arrangement in shared hosting as well as privacy and resource availability of dedicated hosting.
Why to switch to VPS hosting ?
It is observed that VPS hosting is preferred for its superior availability of CPU resources in comparison with shared hosting which is standard entry-level hosting for almost every new site that enters the World Wide Web. There are many users who explore VPS hosting to develop technical proficiency of managing a dedicated server.
As mentioned earlier, shared hosting is a standard entry point for majority of websites. However, there are many factors that necessitate a switch to the next logical level of hosting. Following are some scenarios that call for a shift to VPS hosting from shared hosting.
- Unmanageable traffic
As a consequence of all your efforts to establish your online business, your website may start experiencing heavier traffic than it can be managed with help of limited resources in a shared environment. This may result in excessive pulling of resources forcing your host to notify you about the same. This can be considered as a warning bell to shift your site to VPS hosting.
- Security upgrade for better reliability
Many website owners feel the need to upgrade security attributes of their sites by accessing an array of exclusive resources. Every website should be supported with a consistent stream of resources for enhanced reliability. There may be a need to improve security aspects with help of Secure Shell Access or SSH. These actions are not possible in shred hosting due to its inherent limitations. Hence a move to adopt VPS hosting package may be felt.
- Superior access to server
It is not possible to execute number of advanced actions in absence of a sound control on server. Therefore it is observed that users of shared hosting are not able to install custom applications or execute custom configuration of server. Greater controls may be necessary to have a check on users. In VPS hosting you can enjoy an excellent control over user access as well as allow your users to gain access to servers.
Factors to consider while choosing VPS hosting
VPS hosting entitles users with a broad spectrum of options. Once you have made up your mind to switch over to VPS hosting, you need to evaluate some important aspects as explained ahead while choosing appropriate options.
Choosing an operating system
This the biggest decision while moving into VPS environment. You are entitled to have a separate operating system exclusively for running your Virtual Private Server. While choosing between Linux and Windows operating system, you need to understand that Linux operating system is an entirely different choice than Windows. Unless your site is required to run on ASP.net or ASP, you will be justified to choose Linux operating systems to enjoy a wide assortment of its perks.
Choosing between managed VPS Hosting and unmanaged VPS Hosting
This is a new feature of hosting especially for users of shared hosting since there is no server management at user’s end due to absence of server access. VPS hosting offers root server access and therefore users need to decide between managed VPS hosting and unmanaged VPS hosting.
In managed hosting, your hosting service provider is entrusted with responsibility of managing, maintaining and monitoring server performance. However, if the user wants to keep all controls by shouldering responsibility of securing and monitoring server performance it is called as Unmanaged VPS Hosting.
Unmanaged VPS hosting is reserved for techno savvy users who are comfortable with all ins and outs of server operations such as configuration, security patching, maintenance, and monitoring to name just a few.
Users with no in depth technical knowledge should choose managed VPS hosting. It should be noted that sever management approach and the extent significantly differs depending on different hosting providers as well as variety of managed VPS hosting plans. This can be a basis for comparison between different VPS hosting plans from different vendors. VPS hosting is sometimes offered as managed VPS hosting by default.
Scalable and redundant resources
One should evaluate redundancy of VPS hosting data center with number of backup systems in place to support consistency of resource availability. Redundancy of a data center depends on availability of backup power, multiple generators, and so forth. The redundancy should also cover backup servers, and multiple telecom service providers for incessant website availability. Your VPS needs to scale with demand fluctuations for a smooth website performance. Scalability is also associated with redundancy. Many times surplus resources can facilitate scalability. Therefore scalability and redundancy must be assessed while choosing VPS hosting or exceptional uptime.
Conventional and cloud based VPS hosting
There is a common confusion between cloud based VPS hosting and conventional VPS hosting because these are associated with virtualization and are dependent on main server for their operations.
We have already acquainted ourselves with a conventional VPS server. Unlike these conventional VPS, a cloud based Virtual Private Server is associated with several clustered servers. This frees cloud VPS from limitations of resources that are inherent to conventional VPS. One can go on adding storage, memory, and other resources in cloud VPS with practically no limitations. Cloud based VPS does not suffer from downtime due to resource starvation.
In conventional VPS hosting, one should be keen on knowing the specifications because a properly configured VPS boosts website performance to a great extent. These specifications include processor capacity, disk size and RAM Ideally 20GB storage and 1GB RAM is a bare necessity. One can go on adding on to these by having a better idea about the sites actual requirements. In order to get a fairer idea, you need to check space requirement, status of traffic, and so forth.
It is always better to study limitations on data transfer imposed by the service provider. Choice of particular Linux distribution is also influenced by the kind of website that is going to be powered by VPS hosting.
Quality of customer support
Unexpected events, technical glitches should not hamper your site’s performance. Therefore a highly responsive technical team must be available via multiple means of access on round the clock basis.
While choosing a VPS hosting provider it is always better to take advantage of a trial period if any. It is the most ideal way to try server monitoring systems. These are most commonly offered as periods with a money back guarantee.
