One of the most popular trends in the world of hosting today is cloud hosting. This type of hosting gained popularity due to its efficiency, especially because of its numerous advantages over shared hosting services and sometimes even surpassing dedicated servers. Cloud hosting services are done on multiple virtual servers, which pulls resources from underlying networks of physical web servers often located from different locations and even from different data centers. From that alone, we can see why cloud hosting is the future. Let’s find out more about cloud hosting to better understand it.
Cloud Hosting Defined
Cloud hosting services exist as an alternative to traditional web hosting services from which a website or web application is hosting using a single machine (server). It can also be considered as an extension of clustered hosting service, from which a website is hosted using multiple servers. Cloud hosting service uses a vast network of underlying physical servers located from different places and even from data centers worldwide.
IaaS and PaaS
There are two main types of cloud hosting services, IaaS (Infrastructure as a Service) and PaaS (Platform as a Service).
- IaaS – client is provided with a virtualized hardware resource or a cloud hosting with almost nothing preinstalled. With this type of service, the client can easily install any kind of software and OS package they want and need before building a website or web application.
- PaaS – client is provided not only with a virtualized hardware resource but also with a software environment such as solution stack, consisting of an operating system, database support, web server and programming support. With this type of service, the client can go right away to the website or web application development or deployment.
Your choice will depend on your needs, your level of expertise and dedicated time. Most of the time, IT experts, and larger companies will choose IaaS to build a customized solution stack. An individual or small team may choose PaaS for easier development and deployment.
Features of Cloud Hosting
Like what we’ve learned earlier, a cloud hosting service offers many different features, but the most prominent are:
- Reliability – a cloud hosting services don’t rely on a single instance of a physical server, instead, they use a vast network of physical web servers located in different places. The resources are pulled from the underlying network, therefore, even of one server went down, all websites or web applications won’t experience availability disruption even though the resources are diluted. Some cloud hosting platforms can even survive an entire data center going down as they rely not only on a single data center, often located in different parts of the globe.
- Scalability and flexibility – in a cloud hosting environment, resources are available real time and is easily accessible. If a website or web application requires more resources because of the increase in traffic or implementation of a new feature, the client can easily tap into additional computer power in a matter of clicks.
As you can see, cloud hosting will slowly become the future because of its easier scalability and flexibility not found in traditional web hosting.
