IaaS, SaaS, PaaS, they all sound like unreal words from a comic book.
Actually, they are all different implications of what we called “cloud”. These are 3 pure versions of the options that you have when you want to use cloud technology.
SaaS (Software as a Service)
This is the most well-known variant of a cloud. Many applications that you use are based on this model: Google Apps, Dropbox, OneDrive and many more. They deliver their service over the internet. Users can use it through their browsers, thanks to the companies’ APIs.
Advantages of this model are that the users can manage their data from different devices and a failure of a device doesn’t result in data loss.
PaaS (Platform as a service)
A typical example of this model is Microsoft Azure. It is a platform where the developer can create their applications. It has all that is needed to develop and the hardware is managed by the provider.
Advantages: Provides a secure framework for software development; It helps companies, by taking care of the hardware infrastructure; It provides a platform, that has tools for testing, developing and hosting applications.
IaaS (Infrastructure as a Service)
In this model, companies, like our Cloudware provide the hardware infrastructure (servers, pre-configured or not). Users use it to create virtual machines on it, use it for networking purposes or storage solutions.
Advantages: Instead of purchasing hardware and get dependent from the ecosystem of choice, users can just rent it; Scalability, it is easy to expand; It is safer than having your own servers at your company.
