PaaS, or Platform as a Service, is a cloud computing model that provides a complete development and deployment environment for building, testing, and managing applications. It abstracts away the complexities of underlying infrastructure, such as servers, storage, and networking, allowing developers to focus solely on coding and innovation. With PaaS, users can leverage pre-configured tools, databases, and middleware from providers like AWS Elastic Beanstalk, Google App Engine, or Microsoft Azure, enabling scalable, cost-effective application delivery without the need for hardware management. This service bridges the gap between Infrastructure as a Service (IaaS) and Software as a Service (SaaS), offering flexibility for rapid prototyping, collaboration, and deployment across various devices and platforms.

A) The end-user
B) The PaaS provider
C) Third-party vendors
D) Application developers
Answer: B) The PaaS provider
Explanation: PaaS providers handle the OS, runtime, and middleware, so users don’t have to worry about these layers.
6. What is a common use case for PaaS?
A) Running physical data centers
B) Developing and scaling web applications
C) Manufacturing hardware
D) Storing physical backups
Answer: B) Developing and scaling web applications
Explanation: PaaS is ideal for rapid development and automatic scaling of applications without infrastructure concerns.
7. Which of the following is NOT a typical feature of PaaS?
A) Database management
B) Custom hardware procurement
C) Development tools
D) Application hosting
Answer: B) Custom hardware procurement
Explanation: PaaS focuses on software and platforms, not on allowing users to procure or manage custom hardware.
8. What does auto-scaling in PaaS enable?
A) Manual adjustment of resources
B) Automatic adjustment of resources based on demand
C) Disabling security features
D) Reducing application speed
Answer: B) Automatic adjustment of resources based on demand
Explanation: Auto-scaling in PaaS ensures applications handle traffic fluctuations efficiently without manual intervention.
9. Which model is PaaS part of in cloud computing?
A) On-premise only
B) Service models like IaaS, PaaS, and SaaS
C) Hybrid physical models
D) Local network models
Answer: B) Service models like IaaS, PaaS, and SaaS
Explanation: PaaS is one of the core cloud service models, alongside Infrastructure as a Service (IaaS) and Software as a Service (SaaS).
10. How does PaaS help reduce costs for businesses?
A) By requiring in-house IT teams
B) Through pay-per-use pricing and less infrastructure maintenance
C) By increasing hardware purchases
D) By eliminating software updates
Answer: B) Through pay-per-use pricing and less infrastructure maintenance
Explanation: PaaS allows businesses to pay only for what they use, reducing the need for upfront investments in servers and maintenance.
11. What potential drawback of PaaS involves dependency?
A) Vendor lock-in
B) Unlimited storage
C) Free upgrades
D) Custom coding freedom
Answer: A) Vendor lock-in
