76. Developers want to create a mobile application that requires a runtime environment, developer tools, and databases. The developers will not be responsible for security patches and updates. Which of the following models meets these requirements?
Answer: C
Platform as a service meets the requirements for the mobile application development.
Platform as a service (PaaS) provides developers with a complete environment including runtime, development tools, and databases, while also handling security patches and updates.
A) Container as a service
Container as a service (CaaS) allows developers to manage and deploy containers, but it does not inherently provide a complete development environment with runtime and databases. Furthermore, CaaS typically requires more management of security and infrastructure by the developers, which contradicts the requirement of not being responsible for security patches.
B) Infrastructure as a service
Infrastructure as a service (IaaS) provides virtualized computing resources over the internet, but it requires users to manage operating systems, storage, and security. This model does not meet the requirement for a ready-made development environment and would leave developers responsible for security updates and patches.
C) Platform as a service
Platform as a service (PaaS) offers a fully managed environment that includes runtime, development tools, and database management, making it ideal for developers focusing on application development without worrying about underlying infrastructure security and maintenance.
D) Software as a service
Software as a service (SaaS) delivers applications over the internet, typically for end users, rather than for developers needing a development environment. SaaS does not provide the runtime environment or developer tools required for building applications, thus failing to meet the specified needs.
Conclusion
Platform as a service is clearly the correct choice as it provides the essential components for mobile application development while relieving developers of security responsibilities. In contrast, the other options either do not offer the necessary development tools or require significant management from the developers, which does not align with the requirements stated in the question.
