I Use Virtual Server Hosting… I’m In The Cloud, Right?

| Web Development, Web Hosting | No Comments

So often — too often — the terms “VPS” and “cloud hosting” get used synonymously. A cloud host can offer virtual private servers (VPS), but owning a VPS does not mean the company gets cloud hosting. Confused? The difference is important for business and is as follows.

Virtual Private Servers

I Use Virtual Server Hosting… I’m In The Cloud, Right?VPS emulates a dedicated server instead of hosting on one physical server. The VPS is sandboxed from other VPS customers on the same physical machine. But unlike shared hosting, VPS offers a way for businesses to control the way its server functions. For instance, web services typically need customized settings on the server. With shared hosting, the host rarely changes configurations for one customer, especially if it might affect any other sites hosted on the same server. All sites share the same resources, so web hosts keep shared servers standard across the board.

VPS eliminates the problem of one site affecting another, so the business is given complete control over the server interface. If the business crashes its VPS, it does not affect any other customers’ VPS services.

VPS has several additional advantages over shared hosting, even if it’s not true cloud hosting. First, VPS gives the webmaster better control over server functionality, configurations and added software. If the business has licenses for software such as SQL Server, the webmaster can install the software without going through the cloud host provider. If the webmaster needs to add some Windows server functionality, log in to the console and change the settings. The webmaster can even reboot the machine at-will and won’t affect other customers.

Cloud Hosting

Although cloud hosting has some similarities to basic shared hosting, it’s more powerful and gives businesses a way to serve millions of web requests without ever harming performance. Cloud hosting also offers the power of data centers and content delivery networks. Combined, these resources have a more powerful backend for enterprise businesses with big data and software-as-a-service (SaaS) apps.

Cloud hosting also offers infrastructure-as-a-service (IaaS). IaaS is a service for businesses that need more server resources, storage devices, hardware or networking components. This cloud service is generally used when the business needs more resources but doesn’t have the real estate or IT personnel to handle massive additions to the network.

VPS Versus Cloud Hosting

VPS is a more expensive route than shared hosting, but it offers a dedicated server environment without the dedicated server costs. Small businesses and individual site owners get the most benefits from VPS. VPS is more personalized, and the webmaster can host several sites on the same virtual interface. Bloggers with high traffic spikes, small ecommerce stores or businesses with several websites can take advantage of VPS.

Cloud hosting is beneficial when the business needs more power. The business only pays for the resources used, but it’s generally more expensive because of the large data centers and web farms available. Load balancers control traffic to the business’ website, so the website never falters. Cloud hosting offers 100% uptime, so businesses that rely on website revenue at all hours of the day benefit from cloud hosting.

IaaS and SaaS are also cloud-hosted benefits. Small web services can run on VPS, but VPS is still one server, so it cannot handle the massive amounts of traffic that cloud hosting can manage. VPS is a solution for small businesses or personal websites, but when the business depends on performance, cloud hosting is a solution that has endless scalable resources.

A VPS Smooths A Transition To Cloud Power

| DataBase | No Comments


A virtual private server ( VPS ) provides a number of benefits for the IT needs of any business. There are several things that need to be done by a firm who is considering making the transition to a private cloud. Developing a plan will help them make the most of their change and provides a smooth transition. Some companies prefer to use the services of a third party host, while others keep their IT services in house. Both of these are viable options and are appealing in their own way.

The first thing that a company needs to consider is whether they are going to outsource their VPS services. Outsourcing IT services minimizes the expenses that are associated with a private cloud. Small businesses may find this ideal, as they do not have anyone on their pay roll to handle the tasks of virtualization. Firms, which are experienced with cloud management, may find it beneficial to keep their IT services in house.Considering costs and goals are another issue that needs to be included in a transition to a private cloud. A company should develop a plan for what they want to accomplish. This may be as simple as data storage, or it may be complex and include online marketing. Security is an issue that should be considered and will influence the transition to a private cloud as well. Once a firm has decided on their goals, and the amount of money in their budgets, they can begin to look for their provider.

The specifications of the host server are a prominent consideration and will affect the uniformity of the entire system. Choosing a uniform processor speed is the easiest way to begin, as it is always easy to upgrade the amount of RAM. Replacing a local disk is much more difficult and will cost a firm more in the long run. Deciding these issues in the beginning will help to make the transition smooth and is the proactive way to eliminate any problems before they appear.

The VPS can then be chosen, and a company should be sure they are aware of their operating budgets. Spending money on this service should be seen as an investment in the intellectual infrastructure of the company. Efficiency will be maximized, and this will compensate for any extra capital that has to be spent.

Storage issues are another central component of a private cloud. VPS can provide their clients with variable amounts of data storage, and businesses will be able to increase the performance and efficiency of their individual machines. Data, that is stored on the host server, is accessible to any of the machines that are working inside the cloud. Backing up data in this manner can also be used to minimize problems that are associated with a crash of the hosting machine.
Data should be able to be recovered fairly easily, and companies need to know how much information is essential to their daily operations. Accommodating for the essential data will ensure minimal difficulties in the event of an emergency. Offsite backup should ideally store data in a separate location. This will enable a firm to have certain information always available. Hosts will often include a certain amount of data storage in their services.

Transitioning to a private cloud is ultimately beneficial to any sized business, but a company needs to be sure they develop a plan to ensure success. Deciding on outsourcing to a VPS is one of the first considerations. Companies need to know exactly what their goals are and how much data they need to store. A disaster recovery plan can round out the transition and ensures data will not be lost in an emergency.
