Virtual Private Server (VPS) aka Virtual Dedicated Server (VDS) is actually installed on computer serving/hosting multiple websites. Even a single computer can be a VPS with its own operating system that runs the hosting software for specific use. Each VPS is equipped with web server application, a mail server and specialised program, a File Transfer Protocol (FTP) for multiple operations like blogging or e-commerce. During the last few years, VPS based hosting became quite popular and it’ll continue to escalate with advancement of virtualisation technology. There’re several reasons for organisations to host websites or particular applications over a VPS. Leaving less carbon mess and being scalable plus painless, many organisations thus prefer VPS over other managed hosting services.
Shared or collective web hosting will soon be history. With a pool of companies out there selling servers and keeps on hoarding thousands of customers simultaneously over a single web server, reliability factor seems to have diminished. This seriously impacts a website’s uptime and performance such as if web servers also host a 12 year old aspirant programmer, there’re more chances for frequent website crash. Ask yourself honestly and determine if you’re willing to take such risks; the answer is probably “NO” and that’s more important for business entities. Much inclination has been towards green and environmental friendly technology. It creates less waste while use resources more efficiently. With dedicated server hosting, you’re simply hoarding entire resources at your disposal which means more electricity consumption. However with a VPS, resources are allocated more properly and being virtual; it creates less carbon footprint. Multiple tasks can be performed without recurrent crash and hang-ups.
Some websites are already established and there’s not much variance with online traffic. Scalability isn’t a considerable factor here but for a newly developed website with further hope of growth. In-time, your site will gather traffic and you might think of adding a few services that calls for scalability. It’s simply following a set of procedures allowing minimum or zero downtime plus no technical issues. With managed hosting, entire tasks are amassed in a “container”; that’s what it’s called. This alleged “container” covers a certain amount of resources depending on purchased package. If you need to upgrade your RAM quickly, it’s because of a high surge of visitors and adding RAM is possible with simple click of a button. As for dedicated hosting, you need to physically install RAM that takes a lot of time, effort and cost.
