How does cloud computing become profitable?

What is cloud computing?

Cloud computing services offer convenient pay-as-you-go models that eliminate the high costs and effort of maintenance. Cloud providers host infrastructure, platform and software offerings that you can rent. This gives your company the flexibility to adapt the use of cloud computing services to changing requirements.


Infrastructure-as-a-Service (IaaS)

IaaS is the basic building block for cloud-based IT. In this model, a cloud provider hosts infrastructure components that are traditionally located in local data centers. Servers, storage, network hardware and hypervisors (virtualization layer) are usually on site. With IaaS, your company can choose when and how to manage workloads without having to buy, manage, and support the underlying infrastructure. With IaaS, your infrastructure is like a pay-as-you-go model. ready for use quickly.


Platform-as-a-Service (PaaS)

PaaS is based on the IaaS model, but is typically intended for hardware and software tools for application development. In addition to providing infrastructure components, cloud providers host and manage operating systems and middleware that your developers need to build and run applications. PaaS offers an on-demand pay-as-you-go model.


Software-as-a-Service (SaaS)

With SaaS, cloud providers host and manage the entire infrastructure and applications for end users. If your company chooses a SaaS model, there is nothing to install. Your users can log in and use the cloud provider's application on their infrastructure immediately. So you do not need to worry about the maintenance of the software, just how to use it. SaaS is available as an on-demand model or on a subscription basis.
