What Is Cloud Computing?

Cloud Computing

Cloud computing is the availability and delivery of various computing services through the internet. These computer systems generally comprise of servers, storages, databases, software, networking and more.

These computing services are categorised based on either cloud location or the service offered by the cloud. These services are rendered by companies offering cloud computing services in Sydney and across the world. They are known as cloud providers.

When classifying cloud based on location, they fall under:

  • Public
  • Private
  • Hybrid
  • Community Cloud

Service cloud offerings are categorised as:

  • IaaS  (Infrastructure-as-a-Service)
  • PaaS (Platform-as-a-Service)
  • SaaS (Software-as-a-Service) or,
  • Faas (function as a service)

For the purpose of this post, we’re going to look at the different types of cloud computing services, namely IaaS, PaaS, SaaS, and FaaS.

These four categories are known as cloud computing stack as they fundamentally build on each other.

Infrastructure as a Service (IaaS)

At the basis of cloud computing services lies IaaS. This category lets you rent out IT infrastructure such as servers from a cloud provider on a pay-as-you-go basis.

Platform as a Service (PaaS)

This platform-based service is a development and deployment category that allows users to develop, test and manage software applications using resources that lead to seamless delivery on cloud-based apps. Through PaaS, you have peace of mind when setting up or managing basic infrastructure servers, storage, networks, and databases.

Software as a Service (SaaS)

Businesses in the cloud market often use SaaS to deliver applications from third-party vendors over the internet or on a subscription basis. This cloud computing service allows businesses in Sydney to host and manage software applications without downloads or installations, seeing that it is web-based.

Function as a Service (FaaS)

Here’s another layer that has PaaS to it, but here you’re able to deliver code without the complexity of infrastructure. Virtual servers, containers, and application runtimes are nothing to concern yourself about, all you do is focus on individual functions.

There’s a lot more to cloud computing services, and cloud providers in Sydney are able to provide plenty more cloud services than you can imagine.
