A VPS runs its own copy of an operating system (OS), and customers may have superuser-level access to that operating system instance, so they can install almost any software that runs on that OS. For many purposes they are functionally equivalent to a dedicated physical server, and being software-defined, are able to be much more easily created and configured. They are priced much lower than an equivalent physical server. However, as they share the underlying physical hardware with other VPSes, performance may be lower, depending on the workload of any other executing virtual machines.
Unmetered hosting is generally offered with no limit on the amount of data-transferred on a fixed bandwidth line. Usually, unmetered hosting is offered with 10 Mbit/s, 100 Mbit/s or 1000 Mbit/s (with some as high as 10Gbit/s). This means that the customer is theoretically able to use ~3 TB on 10 Mbit/s or up to ~300 TB on a 1000 Mbit/s line per month, although in practice the values will be significantly less. In a virtual private server, this will be shared bandwidth and a fair usage policy should be involved. Unlimited hosting is also commonly marketed but generally limited by acceptable usage policies and terms of service. Offers of unlimited disk space and bandwidth are always false due to cost, carrier capacities and technological boundaries.
You could think of the sites that share your server as your roommates; there's really not that much separating you from them. Sure, you can close the bedroom door, but they can still cause nightmares for you in the kitchen and the bathroom. In web hosting terms, all the sites share a single server's resources, so huge traffic spike on Site A may impact the neighboring sites' performances. It's even possible that another site could take down the shared server altogether, if it crashed hard enough.
You also want a web host with 24/7 customer support—if not by phone, then at least by chat. Forums, knowledge bases, and help tickets are all well and good, but sometimes you just need to communicate with another human to get things ironed out as quickly as possible. That said, not all 24/7 customer support teams are equal. Companies like GoDaddy and Liquid Web boast incredibly knowledgeable and helpful customer support squads—a fact that we confirmed in our in-depth reviews of those web hosting services.
You get 24/7/365 basic customer support for all the plans. If you need a team of server-admin experts to support you, we offer a fully-managed support plan for an additional charge.

People often think that a web host is the main cause of a slow website but, this is often not the case. When picking a provider, it's important for find a hosting provider that is close to your users and has a good amount of RAM and fast CPU power. Beyond that, it's often the way the website is set up that slows it down for users. To ensure that your website speed is optimal for users you need to make sure you pay attention to the following:
It shouldn't come as any surprise that, like other web host providers, A2 Hosting's unlimited plans aren't actually unlimited. It expect you to use its service like "similarly situated customers." This is like being on a highway. If everyone is going a few miles above the speed limit, you're probably okay, but if you're barreling down the fast lane past everyone else, you're probably going to be asked to slow down.
On the plus side, SiteGround offers free automatic daily backups, access to the Cloudflare CDN, high-performance SSDs for all plans, unlimited email accounts and integration of the free LetsEncrypt SSL certificate into sites. The company does limit bandwidth and storage, but even those who claim to offer so-called unlimited bandwidth and storage really have some limits in its terms of service.
I was running a small private weather website in AWS and the satellite images got "picked up" by a news website and they regularly use them during major weather evenings. AWS' 12c per GB of outbound network traffic made things expensive and VPSServer makes this a lot more manageable and has excellent data volumes included with the price of the VPS. I also get many more CPUs for the price compared to AWS, so I am a happy customer.
