Types of Cloud Computing Services

Cloud computing involves providing access to a shared pool of computing services. That access is via a proprietary network or the Internet. Providers deliver these services on a pay-for-use basis. The term "cloud" refers to data centers all over the world. These data centers provide the hardware that cloud services need.
The Three Main Cloud Computing Types

  • Infrastructure as a Service (IaaS)

In this model, the provider hosts the hardware and software. They also host other components of the infrastructure. The provider maintains the system and handles backups. The IaaS model is scalable and ideal for temporary workloads. Customers pay per use, which allows them to avoid the cost of buying their own hardware and software.

  • Platform as a Service (PaaS)

With the PaaS model, the provider offers the hardware and software that customers need to use an application. This means that the customer does not need to buy the necessary resources or invest in their upkeep. They will not replace their entire infrastructure when using the PaaS model; instead, they will use it for key services. Most PaaS platforms have a focus on software development. These platforms provide customers with certain advantages. The advantages include frequent  upgrades to features of operating systems. The PaaS model also helps development teams to collaborate more effectively.

  • Software as a Service (SaaS)

In most cases, SaaS refers to end-user applications. With this model, the customer no longer has to install or run applications on their own computers or other devices. This means that they do not have to cover the cost of licensing software or of maintaining it. Instead, they pay for a subscription, which replaces the cost of licenses.

Each type of cloud computing can deliver clear advantages depending on what the customer needs. The most obvious advantages include scalability, agility, and increased efficiency when developing prototypes.
