A Purchasing Guide to Virtual Private Servers


vps

A Virtual Private Server (VPS) is a virtual machine which is sold as a service by an Internet Hosting Service. A VPS has its own copy of an operating system which it run so that they can install any software compatible with OS. They are equivalent to a dedicated physical server by functions. Their price is much lower than an equivalent physical server.

SSD drives are used in this plan which is foundation for data transmission and quick page loading. Some are offering Cloud VPS plan. This plan allows people to increase and decrease the amount of storage, bandwidth, RAM which is according to the business requirement. SSL certificates are provided by some companies to enhance the website security which is helpful in taking payments. Some common features are there which all companies are providing:

Get these answered from your hosting provider:-

VPS Hosting plans cover the gap between entry level web hosting plans that offer particular services such as PHP, MySQL with a limited amount of disk space on a shared server and dedicated servers. VPS plans are hosted on FreeBSD or Linux but exist on Windows operating system.

What are the specifications of the host server?

VPS Hosting Server has some specifications which are following:

Software: Vps can be configured with multiple Linux distribution, CentOs-based, Plesk web hosting environment.

Network Connectivity: For network four independent providers are necessary: Level (3), Abovenet networks, Cognet Communications and Tinet.

How many VPS instances are run on the host server that you’ll be on?

Dedicated servers ensure that nobody can share any type of resources with anyone. Anybody can get the full memory, storage, power and network access from its hardware. VPS resource sharing may lead site downtime if demand will be increased according to the capacity.

Resources provided under VPS hosting:

  1. VPS hosting provides independence to one user from other users on the same server. Users have all resources to themselves.
  2. VPS hosting is filling the gap between the dedicated hosting services and shared hosting services. Anyone can connect technically to shared hosting environment but at the same time one enjoy the privacy in a dedicated server.
  3. Vps hosting is providing power and functionality of the dedicated server at lower cost.
  4. User can install any kind of software.

Resource Contention in VPS:

There is a concept of noisy neighbour who is the customer on a server uses his or her share of server resources. Disk IOPS (I/p o/p operations per second) have shared resources in VPS and cloud environment. The customers of VPS can purchase server with IOPS without any investment in a dedicated server. Resource monitoring will be done according to time and will decide predetermined limits past which user will upgrade.

Advantage & Limitations of VPS:-

Many advantages and limitations are there:

  1. Reliability: A good VPS hosting provider has better uptime reliability.
  2. Server security: VPS provider gives assurance of security programs and policies.
  3. Standard top of the line hardware: For a good VPS provider hardware is housed for virtual private space. It includes a dedicated RAM, top-of-the line CPU and a sizeable storage.
  4. Customizability: A good VPS should be easily customized according to the users’ requirements.
  5. Affordability: VPS is hybrid between a dedicated server and a shared server. VPS plan is able to deliver the power of dedicated server as well as shared server on the same.
  6. Individual gateway: It should provide Individual Web, POP, FTP, SMTP gateway and IMAP servers.

What VPS is not/ what vps lacks? :-

The VPS is least concern about hardware. VPS looks like a device with a specific set of hardware. If the VPS hardware fails then this can be difficult to restore as well as require a high per hour “remote hands” fee. User don’t gain root access but the files and scripts are spread across a cluster of machines with automatic scaling.

Conclusion:

Many companies are providing VPS hosting as an extension for web hosting services. A VPS hosting is dynamic means it can be changed at run-time. Additional resource of hardware can be added at run-time.During the server runtime VPS can be moved to other hardware.

Virtual Private Servers (VPS) Web Hosting


A Virtual Private Server (VPS), also referred to as Virtual Dedicated Server (VDS), provides the features of a dedicated server for multiple web hosting customers to share. At first instance it sounds contradictory, how can you have a dedicated server if it is being shared by multiple users? Isn’t that a regular shared or virtual hosting environment? It is true that with a Virtual Private Server you still share system resources like the CPU and RAM with other users but the resources are allocated in such a way that you cannot tell that the system has anyone else on it, much like a dedicated server. So resources are usually setup in such a way that each hosting client is only allowed to use an allocated percent, meaning that resources assigned to you will always available to you.

Advantages of Virtual Private Server (VPS) web hosting

Most hosting customers would rather have complete control of their server environments. They don’t want to be hosted on a server with tens or hundreds of other users, who could easily use up all the resources or cause the server environment to be unstable. But at the same time most websites don’t need a dedicated server. The Virtual Private Server (VPS) alternative is a very attractive niche hosting solution for a fairly large chunk of web hosting clients who would like the stability of a dedicated server but on a smaller scale. With the resources setup in such a way that each person can only use what is allocated to them, your site will be more consistent because it will always have the same amount of access to the CPU, memory, and bandwidth. Virtual Private Servers are also more secure since even as you share the memory and CPU time, you are allocated your own file system. If a website on the server is hacked, the hackers will only have access to that particular file system and would not harm the other websites. A VPS is also much cheaper than a dedicated server.

Disadvantages of Virtual Private Server (VPS) web hosting

Now that you have read the pros of a VPS you are probably thinking that this is the best thing since sliced bread. Well, almost – as is the case with every other type of hosting service, not all providers setup or define Virtual Private Servers, also known as Virtual Dedicated Servers, the exact same way. You must make sure that your provider guarantees that their setup is robust enough to handle operations at a peak level. A trick used by many providers in the reselling and shared space is ‘overselling’. What this means is selling more in terms of services than what physically available, with the hope that the end users wouldn’t use up all the service that were advertised to them. In the realm of VPS this can be a bit more serious, since at least the expectation is that you are operating in a more robust environment and many clients could be running more intensive applications like message boards or custom web applications. A shortfall of resources could end up causing problems for everyone hosted on such a server, therefore negating the benefits of a VPS. In a shared or dedicated environment you might be able to access more resources during peak or spike periods but since the VPS environment limits you to to your slice of the server resources, it can be a drawback.

As if the technology rich lingo of regular web hosting wasn’t enough, the VPS services add a few new wrinkles. Apart from storage space and bandwidth you must also deal with CPU cycles and RAM. So you will see ads for hosting that might include *** MHz and *** MB RAM to go with the usual hosting related features. It is somewhat harder to figure out how much CPU time or RAM you might need, so seek out a hosting provider that will provide you with some benchmarks and the ability to upgrade or downgrade the VPS service if needed.
