Which of the following definitions of serverless computing BEST explains how it is different from using VMs?
Correct Answer: D
Explanation This is the best definition of serverless computing that explains how it is different from using VMs (Virtual Machines). Serverless computing is a cloud service model that provides customers with a platform to run applications or functions without having to manage or provision any underlying infrastructure or resources, such as servers, storage, network, OS, etc. Serverless computing is different from using VMs in the following ways: Serverless computing allows developers to focus on writing code and organizations to focus on business, rather than spending time and effort on managing or scaling VMs or other infrastructure components. Serverless computing is event-driven and pay-per-use, which means that applications or functions are executed only when triggered by a specific event or request, and customers are charged only for the resources consumed during the execution time. Serverless computing is more scalable and flexible than using VMs, as it can automatically adjust the capacity and performance of applications or functions according to demand or workload, without requiring any manual intervention or configuration.

Correct Answer: A
Question 18
An organization is developing a new online product. The product must: * Minimize organizational infrastructure and comply with security standards. * Minimize organizational compliance efforts. * Focus on application development and increase speed to market. Which of the following should the organization consider, given the requirements listed above?
Correct Answer: A
Explanation One possible answer is: A: Use cloud-native serverless services. Cloud-native serverless services are a type of cloud computing that allows developers to build and run applications without having to manage servers, infrastructure, or scaling. Cloud-native serverless services can help the organization meet the requirements listed above, as they can: Minimize organizational infrastructure and comply with security standards. Cloud-native serverless services are fully managed by the cloud provider, which means the organization does not have to provision, configure, or maintain any servers or infrastructure. The cloud provider also handles the security aspects of the serverless environment, such as encryption, authentication, authorization, patching, and monitoring. The organization can focus on developing the application logic and rely on the cloud provider to meet the security standards12. Minimize organizational compliance efforts. Cloud-native serverless services can also help the organization reduce the compliance burden, as they can leverage the compliance certifications and attestations of the cloud provider. The cloud provider can ensure that the serverless environment complies with various regulations and standards, such as PCI DSS, HIPAA, GDPR, ISO 27001, etc. The organization can inherit the compliance posture of the cloud provider and avoid the hassle of auditing and validating their own infrastructure12. Focus on application development and increase speed to market. Cloud-native serverless services can also enable the organization to accelerate the development and delivery of their online product, as they can write code using their preferred programming languages and frameworks, and deploy it quickly and easily to the serverless environment. The serverless environment can automatically scale up or down based on the demand, ensuring high availability and performance. The organization can also integrate serverless services with other cloud services, such as databases, storage, analytics, etc., to create a full-stack application12.
