The "slashdot" effect is the main problem which will lead to VPS hosted website crashes more than any other. For example, if a VPS plan has an allocation of 2 GB of RAM and 2 CPU cores with a maximum support for around 200 simultaneous users of a complex Drupal or WordPress site, a popular social media link may temporarily increase traffic to a website 10x or 100x. In these cases, the VPS will crash... unless the overflow can be managed by burstable RAM or elastic cloud scalability. In elastic frameworks, the network monitoring software simply launches a new VPS instance with a cloned & synchronized version of the website files that can manage the additional user demand. When the traffic spikes decrease, elastic server networks can automatically scale down VPS instances to conserve resource utilization in production.
Learning how to set up a VPS after upgrading from shared hosting is like leaving the kiddie pool to dive into an Olympic-sized one. You have a lot more room and features to play with, but you’ll need to find your footing before you can start having fun. Now that you know how to configure your VPS, you’ve become acquainted with the command line, which will make it a lot easier to set everything up to your liking.
VPS stands for Virtual Private Server and refers to a private, emulated dedicated hosting environment created through virtualization on a host (a computer or other device connected to other computers or devices via a network), server (called the “parent server”), or cluster of servers. It acts like a physical server but, in reality, it’s a piece of software that’s emulating dedicated hardware.
VPS hosting works the same as Shared Hosting, except you have additional features such as your own WHM panel.

A VPS doesn’t just have more RAM, disk space, and a  proprietary share of CPU than a shared account. Depending on the provider, some VPS plans offer burstable memory, which is a pool of RAM set aside for extraordinary events. This is the stuff that can help counter the so-called “Digg-effect,” that much-whispered about occurrence that’s the simultaneous hope and fear of everyone who runs a web site. When you have an unexpected high traffic event, burstable memory will call on a pool of reserved, shared memory to satisfy the needs of temporary high traffic. This is not available on shared servers and, while the necessary memory is available on a dedicated server, your site might not get the kind of traffic on a daily basis to justify the expense of a dedicated server. Again, not all VPS plans have burstable memory, so ask your provider if their VPS plans do.
Do you remember those times when you were living on a college campus with very noisy roommates? Or maybe they were super quiet and you enjoyed every day? The point is, it was a gamble - you never knew whom you ended up with. This is pretty much the same as having shared hosting account - you haven’t the faintest idea who is your roommate on a server. The analogy may sound funny but if someone on a shared server becomes a distributed denial of service (DDoS) attack target or get blocked for mass mailing, other accounts on the server will be affected as well. Also, if a shared account abuses server resources, the whole server will be impacted. Using a VPS is like owning a house with a 9 foot privacy fence. You won’t be bothered no matter what your neighbors are doing.

VPS hosting is like you are living in an apartment complex. It means that other people are living in the same building, but you have your own secure apartment. You will get more room and restrictions will be fewer as compared to living in a dorm. It also means that if your neighbour is misbehaving, it is the problem of owner of building, not yours.

Shared hosting is cheap and allows you to install any gallery platform you wish if a hosting plan meets its requirements. But be careful and study your hosting provider’s Acceptable Use Policy thoroughly. The truth is, that even if they claim unlimited storage with their plans, they don’t want you to use much of it. On the contrary, they secretly hope that you will use less and they can host many other clients on the same server. For that reason, hosting providers usually put limitations on their policies (e.g. “no more than 10 GB for images,” etc.). So don’t be convinced that you have unlimited storage without first checking your shared hosting provider's policies or you will find your account suspended someday.
Of course, virtual private server providers have noted this trend as well. Not to be left behind, there are several providers all over the world who allow you to pay for servers via bitcoins in addition to other methods as well.

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.

Shared hosting is like you are living in a room with a lot of friends. It means you must fit in the same room and you must split the cost of several things because it is affordable and cheap. However, several individuals are sharing the same space, it means everyone needs to live within a space with restricted resources among them. You will have to use the same things (that sounds a little unhygienic).
Simply put, shared hosting means your site will share the same server as many other sites. It’s usually the cheapest option but comes with limited bandwidth, administration, and performance capabilities. VPS hosting is a more premium option, with the ability for greater customization and increased performance. But, as with any premium service, you’ll have to pay more to get more.

Server virtualization is possible thanks to specific software that behaves like a layer between the hardware and the server’s operating system. One such piece of software is known as Virtuozzo Containers, which sadly can’t provide actual virtualization. With this technology, certain resources are shared, root access is restricted, and the operating system can’t be modified etc. A high-quality VPS hosting provider will use XEN Hypervisor instead, which allows you to install any OS you want and gives you total autonomy over all resources including root access and the number of customization options.
