A company is planning to migrate its event-driven application to Azure to leverage cloud benefits such as scalability, cost-efficiency, and reduced operational overhead. The application experiences unpredictable traffic patterns, with significant spikes during marketing campaigns. The company aims to minimize infrastructure management to focus more on application development and innovation. Given these requirements, which of the following Azure services would BEST meet the company's needs? Choose the TWO best options from the following.
A
Azure Virtual Machines (VMs), where the company can deploy and manage its own VMs. This option provides full control over the environment but requires the company to handle server management, scaling, and maintenance, leading to higher operational costs and effort.
B
Azure Functions, a serverless compute service that allows developers to run event-triggered code without explicitly provisioning or managing infrastructure. It automatically scales to meet demand and charges only for the compute time used, aligning with the company's goals of minimizing management and costs.
C
Azure Kubernetes Service (AKS), which offers managed Kubernetes for deploying, managing, and scaling containerized applications. While AKS reduces some management overhead, it still requires the company to manage containers and orchestration, making it less ideal for minimizing operational tasks.
D
Azure App Service, a fully managed platform for building, deploying, and scaling web apps and APIs. Although it offers some level of management reduction, it may not be as cost-effective or scalable for event-driven applications with variable traffic as serverless options.
E
Both Azure Functions (B) and Azure Event Grid, a fully managed event routing service that enables event-driven architectures. Azure Event Grid works seamlessly with Azure Functions to provide a scalable, serverless solution for event-driven applications, further reducing management and operational costs.
