An organization wants to run their custom application in the cloud in a flexible and scalable way without managing any infrastructure. Which service model should they use?
B. Platform as a service (PaaS)
Explanation:
Platform as a Service (PaaS) allows organizations to run their custom applications in the cloud without managing the underlying infrastructure (e.g., servers, storage, networking).
PaaS provides a platform with the tools, runtime environments, and scalability options needed to develop, deploy, and manage applications efficiently.
E.g.:
- Google App Engine is a fully managed PaaS offering that allows developers to build and deploy applications without managing infrastructure. It provides automatic scaling based on traffic and integrates with other Google Cloud services for storage, databases, and machine learning.
Features: Supports various programming languages (e.g., Java, Python, Go, Node.js), automatic scaling, built-in load balancing, and integrated monitoring tools.
Why not the other options?
A. Infrastructure as a service (IaaS):
IaaS provides virtualized computing resources like servers, storage, and networking, but it still requires users to manage the operating system, application runtime, and other infrastructure components. This would not meet the need to avoid managing infrastructure.
C. Software as a service (SaaS):
SaaS delivers fully managed software applications (e.g., email, CRM, productivity tools) over the internet. It does not allow for the deployment of custom applications.
D. Network as a service (NaaS):
NaaS provides network-related services, such as virtualized networks, but it is not directly relevant to running custom applications in the cloud.
An organization wants to run their custom application in the cloud in a flexible and scalable way without managing any infrastructure. Which service model should they use? - Highly depends on what is a custom application - it it already exists it might be dificutl to run in a platform as a service mode.
