While IaaS provides virtual infrastructurei.e. servers, storage and network elements, where users have full control over operating systems, applications and configuration, PaaS provides a platform. The platform includes an environment, development tools and other components for creating and deploying applications. Users are only responsible for their own applications and data, while the platform is supported and managed by the provider.
IaaS vs. PaaS: Differences in development and scalability
You will feel the differences, for example, when developing applications. Users have flexibility to develop and deploy applications according to your needsthey can use their own tools and technologies to do so. In contrast, PaaS provides a specific development framework and tools for easier application development and deployment.
In terms of scalability, with IaaS, users have more control over scaling - they can add and remove resources as needed. With PaaS, users may be limited by the capabilities of the provider. But PaaS has its advantages - this model will be appreciated by those who want to develop and deploy applications faster without worrying about infrastructure.
IaaS vs. PaaS - which model is right for you? It depends on different contexts and the specific needs of your organization. Some projects may require the flexibility and control that IaaS offers, while for others, simplicity (PaaS) is the key.
