Have you ever heard or seen these three words: SaaS, PaaS, and IaaS? Cloud services are mainly classified into these three categories. They all seem quite similar, but they have some important differences.
SaaS stands for Software as a Service. It refers to software that users can use as services through a network. Some examples of this are Dropbox, Google Apps, and Microsoft Office Web Apps.
Some important characteristics of SaaS are:
- It is possible to access the service without only a computer, smartphone or a tablet.
- Data can be stored in the cloud.
- Data can be managed and edited with and by multiple people.
SaaS makes up the majority of the features people use when accessing the cloud.
PaaS stands for Platform as a Service. It is a service that provides a set of platforms via the cloud. Typical examples of this might include Sales Force Force.com, Google App Engine, and Windows Azure. Compared to SaaS, these are mainly items used by developers.
Some important characteristics of PaaS are:
- The platform is provided.
- Applications are developed according to system design.
IaaS stands for Infrastructure as a Service. When developing applications, it is necessary to purchase servers and software separately and then operate and maintain them. With IaaS, it is possible to use the server, storage and network resources as much as necessary without needing additional hardware.
Since it is possible to use it with only the minimum functions, advanced technologies are required. However, a distinct advantage is that applications and platforms with a high degree of flexibility can be created.
How was it? Even though we can talk about the cloud in a single word, the services available vary greatly. By knowing more about what’s available, it’s possible to improve our work even more!
