An application development company is considering implementing a cloud solution to help improve time to
market with new software upgrades. The existing application has been in use by customers for several years
and contains a large amount of code. Which of the following types of clouds would be BEST for this company to
implement?
A.
IaaS
B.
XaaS
C.
PaaS
D.
SaaS
Explanation:
Platform as a service (PaaS) is a complete development and deployment environment in the cloud, with
resources that enable you to deliver everything from simple cloud-based apps to sophisticated, cloud-enabled
enterprise applications. You purchase the resources you need from a cloud service provider on a pay-as-yougo basis and access them over a secure Internet connection.
Like IaaS, PaaS includes infrastructure—servers, storage, and networking—but also middleware, development
tools, business intelligence (BI) services, database management systems, and more. PaaS is designed to
support the complete web application lifecycle: building, testing, deploying, managing, and updating.
PaaS allows you to avoid the expense and complexity of buying and managing software licenses, the
underlying application infrastructure and middleware or the development tools and other resources. You
manage the applications and services you develop, and the cloud service provider typically manages everything
else.https://azure.microsoft.com/en-us/overview/what-is-paas/
