Keep firmly in your mind the sort of assets that you require to serve your site(s) when seeking a host. Cost in a VPS is important, but not as key as you might think. VPS resource availability is scalable, so the cost that needs to be looked at is comparable cost from one host to the next. Also – as cPanel revised their pricing model recently, web hosting companies across the board will have to pass those costs on to users sooner or later. You will need to consider the cost of control panel when selecting a VPS plan. Companies like ScalaHosting has developed their own control panel to mitigate this issue – so their users would have little issues with the price hike.
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.
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.
WebSocket's create two-way interaction between a browser and a website possible for a realtime web experience. This is instead of the server needing to be called intermittently to access new information. Websockets are ideal for developing live content and realtime games. Not only do our Turbo Servers make it easier to setup a WebSocket, Turbo allows you to better handle incoming connections and provides enhanced security.
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 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.
