What is Infrastructure as a service (IaaS)?
Infrastructure as a service is a cloud computing platform that delivers services on-demand over the Internet. The service provider manages the Infrastructure while the user installs, configures, and manages the software, including applications, middleware, and operating systems. IaaS is one of the types of services of cloud computing. IaaS has direct control over the operating system and Infrastructure.
It can also be accessed by API key to developing new servers online. Some types of IaaS are Disaster recovery IaaS, Replication IaaS, Productions IaaS, etc.
What is Platform as a service (PaaS)?
Platform as a service offers a development platform where we can provision, run, and manage the application. It provides a complete cloud development and deployment environment with database and management tools. PaaS simplifies the development cycle from the developer’s perspective, and all backend management takes place behind the scenes.
Difference between IaaS & PaaS
| Infrastructure as a service (IaaS) | Platform as a service (PaaS) |
|---|---|
| Infrastructure as a service is a cloud computing platform that delivers computing resources over the Internet. | Platform as a service offers a development platform where we can provision, run, and manage the application. |
| Network architects use IaaS for designing and building data communication networks. | Developers use PaaS for building user interfaces and applications. |
| It is a service model that provides analysis and synthesis of visual data through the use of computer resources. | PaaS offers development tools such as programming languages, Databases, Application frameworks, and other software tools. |
| IaaS enables the usage of virtual machines and virtual storage. | Through PaaS, we can access development and deployment tools for the application. |
| In case, we have to manage many applications on our own, such as operating system, middleware, and runtime. | In PaaS, mainly all the applications are managed by service providers. |
| IaaS provides full customer support, routers, and network topology. Some of the uses of IaaS are High-performance computing (HPC), Big Data analytics, Backup and recovery, and Data warehousing. | PaaS enables speed, collaboration, and managing custom business applications. It is used for building websites and rapidly creating and deploying customer-friendly web apps. |
| Many companies offer IaaS, such as AWS, which has the largest and most used Platform of IaaS, DigitalOcean is the best for high bandwidth applications, Alibaba Cloud, IBM cloud, etc. | The organizations offering PaaS services are Windows Azure, Heroku, Force.com, Google App Engine, OpenShift, etc. |
