PaaS – Definition, examples, opportunities and limitations
After having addressed, in the first episode, the cloud computing service IaaS (Infrastructure as a Service) today we move on to PaaS or Platform as a Service, remembering that the positioning that each type of service occupies within the pyramid, is not random, but represents the interdependence that exists between one and the other. In this sense, each software (SaaS) is based on a platform (PaaS) for which an infrastructure (IaaS) is required.
What is PaaS?
A distributed Paas (platform as a service) is a complete development and deployment environment in the cloud, with resources that allow you to deploy anything from simple cloud-based apps to sophisticated cloud-enabled enterprise applications. You can purchase the resources you need from a cloud service provider on a pay-as-you-go basis and access them over a secure Internet connection.
Basically, you use third-party platforms to offer your own services. This type of service, positioned, in the pyramid, exactly in the middle is between independently managed and fully managed.
Platform as a service examples, opportunities and limitations
A clear example of PaaS are the Ads platforms of the various providers through which online professionals offer dedicated campaigns to their customers: the IT giants, thanks to their powerful infrastructure make available to advertisers the platform to set up the PaaS creativity that will be used for the various campaigns.
The flexibility of providing a service through this platform is one of the main advantages of PaaS. For example, it allows the development of applications from a solid base, thus saving time and money.
The main limitation of PaaS is the need to have competent staff and resources who are familiar with the chosen platform.
In the next section we’ll talk about SaaS analyzing its meaning, its advantages and its limits. We remind you that there is no “one-size-fits-all” solution for cloud adoption. Companies should evaluate costs and benefits and, therefore, decide which is the best model. In a previous article we showed the main differences between IaaS, PaaS and SaaS in cloud computing.
