Although these nomenclatures are not recent, many users are still confused by their meanings. With this in mind, the CodeBlog team has prepared an enlightening article to define each of the terms and simplify the process for you.

After all, what are IaaS, PaaS, and SaaS?

In short, IaaS, PaaS, and SaaS are service formats made available in the cloud, which became widespread after making their presence known in giant technology platforms, such as Amazon Web Services, Google Cloud Platform, and Microsoft Azure. Check out the particularities of each of them below.

IaaS – Infrastructure as a Service

Above all, IaaS – Infrastructure as a Service - is considered the simplest of all categories, since it almost always works the same way, regardless of the selected provider, and provides a scalable and automated technology infrastructure capable of utilizing hosting, networking, and storage directly from its own global servers. In this model, the user only pays for what they consume. In this way, companies have the flexibility to allocate resources according to their demand, without the need to secure software licenses or their own servers.

PaaS - Platform as a Service

Unlike IaaS, which is known for its practicality, PaaS - Platform as a Service - is considered the most complex definition model. This type of solution involves the basic provision of IaaS concepts, as well as features and tools necessary for the development and management of apps in a secure manner, without worrying about infrastructure. In this context, the servers hosting the websites illustrate examples of PaaS. Generally, the companies that adopt the tool are technology giants that have a broad capacity to make various resources available to users on a single platform, such as Google App Engine, Cloud Foundry, and Oracle Cloud Platform.

SaaS - Software as a Service

Finally, SaaS - Software as a Service - is a place that hosts third-party software and can be easily accessed online via a login. Within this solution, the company negotiates a subscription plan and then begins to use the programs and tools necessary for its processes. Typically, SaaS is more commonly used in specific applications and processes, such as customer relationship management (CRM). However, in addition to solutions targeted at the business niche, any user who has already had contact with Google apps, such as Gmail, Google Docs, or Google Drive, has already experienced part of the experience offered by SaaS. Among the main providers and users of this solution are renowned companies such as Microsoft, with Office 365, and Salesforce.

Which is the best model?

The best model, in fact, will be the one capable of meeting your company's demands and needs, according to the level of investment available and the team's implementation and adaptation period.

Above all, the greatest advantage of a cloud available in the three models is precisely the flexibility to offer solutions capable of resolving everything from specific conflicts to a complete structure with multiple applications.
