65. A technical lead wants to migrate all common business applications, including email and fileshares, to the cloud. Which of the following cloud concepts should be used?
Answer: C
SaaS is the appropriate cloud concept for migrating common business applications.
SaaS (Software as a Service) is ideal for migrating common business applications such as email and fileshares because it provides ready-to-use software over the internet, eliminating the need for local installation and maintenance.
A) MaaS
MaaS (Monitoring as a Service) focuses on providing monitoring capabilities for IT infrastructure and applications. This option does not pertain to the migration of business applications like email and fileshares, making it an incorrect choice.
B) PaaS
PaaS (Platform as a Service) offers a platform for developers to build and deploy applications without managing the underlying infrastructure. While it is useful for application development, it is not designed for direct migration of existing business applications, rendering it unsuitable for this context.
C) SaaS
SaaS (Software as a Service) allows users to access software applications over the internet. This model is particularly suited for common business applications, such as email and fileshares, making it the correct choice for the migration described in the question.
D) IaaS
IaaS (Infrastructure as a Service) provides virtualized computing resources over the internet. While IaaS can support the migration of applications, it requires more management and configuration than SaaS, which directly delivers the applications needed without additional overhead.
Conclusion
SaaS is the definitive choice for migrating common business applications due to its ease of use and direct access model. Other options like MaaS, PaaS, and IaaS either do not pertain to the specific needs of application migration or require additional management that is unnecessary in this context.
