Question 65

Software as a Service (SaaS) is the appropriate cloud concept for migrating common business applications.

Migrating all common business applications, such as email and fileshares, to the cloud is best achieved through Software as a Service (SaaS). SaaS provides users with access to software applications over the internet, eliminating the need for local installation and maintenance.

A) MaaS

MaaS, or Management as a Service, is not applicable in this context as it primarily focuses on providing management solutions rather than full software applications. It does not address the needs for common business applications like email and fileshares.

B) PaaS

Platform as a Service (PaaS) offers a platform for developers to build, deploy, and manage applications. While PaaS supports application development and deployment, it does not provide end-users with access to ready-to-use applications such as email or file sharing services.

C) SaaS

SaaS is the correct choice as it delivers software applications via the internet, allowing businesses to use applications like email and file sharing without the need for local installations. This model is specifically designed for common business applications, making it the most suitable option.

D) IaaS

Infrastructure as a Service (IaaS) provides virtualized computing resources over the internet. While IaaS can support the underlying infrastructure for applications, it does not provide the actual software applications themselves, making it less relevant for the migration of business applications like email and fileshares.

Conclusion

SaaS is the definitive choice for migrating common business applications to the cloud, as it directly provides users with the necessary software solutions. In contrast, MaaS, PaaS, and IaaS do not cater to the specific need for readily accessible applications, thereby failing to meet the requirements set by the technical lead.
