In this article we dive into what public cloud hosting actually is, along with its advantages and disadvantages, so you can make the best decision for your business.
What is Public Cloud Hosting?
Public cloud hosting utilizes the resources of a network of physical servers to provide a virtualized hosting environment that’s fast, flexible, and scalable. It’s one of the three main models the cloud computing world is generally divided into, alongside private and hybrid cloud.
The main way it differs from a private cloud is that a public setup provides hosting to multiple clients within the same shared physical server infrastructure. The only overlap you’ll have with other sites are the physical servers themselves — each virtual network stays isolated from the others.
Although this seems similar to traditional shared hosting, the approach to utilizing physical server space is different. It draws from so many different physical servers that the space and resources you have access to are theoretically infinite, and you won’t suffer any lags in performance from other sites sharing the same server.
Advantages of Public Cloud Hosting
This hosting model offers your website a ton of benefits that are hard to find elsewhere. Below are a few of the biggest reasons you’ll want to consider it:
- Scalability. Near infinite scalability. Resources can be increased on demand to meet growing site or traffic requirements.
- Flexible pricing. You share the cost of the physical server environment, with pricing based only on the resources you actually consume, similar to paying for your monthly utilities.
- Extremely reliable. Due to the high number of servers and networks involved, if a single server fails or becomes overloaded your site can simply draw resources from another one. This helps prevent downtime or lapses in service.
- High performance. Naturally high performing, since you’ll have access to a nearly unlimited amount of server resources.
Disadvantages of Public Cloud Hosting
It isn’t the right fit for every situation. It’s worth weighing these tradeoffs before choosing it over shared, VPS, or dedicated hosting.
- Less control over the physical environment. Because your site draws resources from a shared pool of servers, you don’t get the same level of hardware-level customization that a dedicated server offers.
- Shared infrastructure means shared risk. While isolation between virtual networks is strong, it’s still a multi-tenant system — some businesses with strict compliance or data-residency requirements prefer the full separation a private cloud or dedicated server provides.
- Variable costs can be harder to budget for. The same pay-for-what-you-use pricing that makes it flexible also makes monthly costs less predictable than a fixed-rate hosting plan, especially for sites with unpredictable traffic spikes.
Is Public Cloud Hosting Right For You?
It tends to make the most sense for sites with growing or unpredictable traffic that need to scale resources on demand, without paying for a full dedicated server year-round.
If your traffic is steady and predictable, a shared hosting or reseller hosting plan is usually simpler and more cost-effective, since you won’t be paying for elasticity you don’t actually need.
