You’re paying more, so there SHOULD be a minimum uptime guarantee and better server speed. Look for a host that offers 99.5% at a very minimum, although ideally, I’d rather go with someone who offers 99.9%. Search through some reviews as there are many who have put this to the test. For example, any of WHSR’s many web host reviews include an uptime record as one of our key tests.
Some virtualization platforms, primarily "bare metal" hypervisors, do not permit the realtime allocation or alteration of system resources to VPS partitions. Managed VPS plans including cPanel offer the AWStats service for viewing metered bandwidth on web traffic by month & day. Google Webmaster Tools is another good resource for monitoring and calculating the average traffic usage for a website by geo-location, time of day, weekend use, holiday rates, etc.

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.
When you create a website, you have to pay a company to host it on their server. This is a powerful computer that allows anyone on the internet to connect and access your site. The lowest level of server is a shared hosting plan where hundreds of websites (and all their data) are stored on one server with all of the server’s resources up for grabs depending on who needs them.
Dedicated hosting is true to its name. It includes a fully-dedicated host server where 100% of resources are dedicated to your site. VPS, on the other hand, has a dedicated amount of resources allocated to your site from a shared server, essentially giving you a piece of a larger whole. When you have a dedicated host, the entire host is yours to utilize.
RAID storage differentials are largely based on the number of disk drives and synchronized duplicate copies of data files available. SSD storage with Docker containers, Kubernetes elastic cloud networks, and isolated VPS/VM partitions are considered fundamentals in cloud data center architecture today. Many shared Linux webhosts make extensive use of SSD storage in VRAM configurations.

The most obvious and popular reason for a VPS is to run a single website, or multiple websites. However, you can use them for pretty much anything that requires access to the internet – such as a web application like Nextcloud to run your own Dropbox alternative – or to create your own virtual private network to better secure the internet connection of your PCs and mobile devices.
