Minimizing Administrative Effort: Cloud Deployment Solution for Web Application

B

Azure App Service is a platform-as-a-service (PaaS) offering that lets you create web and mobile apps for any platform or device and connect to data anywhere, in the cloud or on-premises. App Service includes the web and mobile capabilities that were previously delivered separately as Azure Websites and Azure Mobile

Services.

The recommended cloud deployment solution to minimize the amount of administrative effort used to manage the web application accessed by external users is Platform as a Service (PaaS).

Platform as a Service (PaaS) is a cloud computing model that provides a complete platform and environment for building, deploying, and managing applications in the cloud. PaaS solutions typically include pre-built components, such as application servers, databases, and development tools, which enable developers to focus on building and deploying their applications without worrying about the underlying infrastructure.

By using PaaS, the administrative effort required to manage the web application is significantly reduced because the cloud provider manages the underlying infrastructure, including servers, operating systems, and network infrastructure. This allows the development team to focus on building and deploying the application while leaving the infrastructure management to the cloud provider.

In contrast, Infrastructure as a Service (IaaS) provides virtual machines, storage, and networking infrastructure, but the administrative effort required to manage the infrastructure is still the responsibility of the customer. This means that the development team would still need to manage and maintain the infrastructure, which can result in increased administrative effort.

Software as a Service (SaaS) and Database as a Service (DaaS) are also cloud computing models but are not recommended for this scenario. SaaS provides a complete software application that is hosted and managed by the cloud provider, which may not be suitable for a web application that requires custom development. DaaS provides a managed database service, which is useful for specific database workloads, but does not provide a complete platform for building and deploying a web application.

In summary, the recommended cloud deployment solution to minimize the amount of administrative effort used to manage the web application accessed by external users is Platform as a Service (PaaS).

The solution provided of using the operational expenditure model for the intended Azure solution is a correct recommendation and meets the goal of using the correct expenditure model for the migration of virtual machines to an Azure pay-as-you-go subscription.

The operational expenditure (OpEx) model is a payment model that involves paying for services or resources on a periodic basis, typically on a monthly basis. This model is preferred for organizations that want to reduce the upfront costs of investments and want to pay only for what they use. This model is also beneficial for businesses that require flexibility to scale up or down resources as per their needs.

In the context of migrating virtual machines to Azure, using the OpEx model means that the company will pay only for the resources used on a monthly basis. This will help in reducing the upfront investment costs and providing flexibility to scale up or down resources as per their needs. Furthermore, the pay-as-you-go subscription in Azure allows customers to stop or start using services at any time without any penalties or termination fees.

Therefore, recommending the use of the operational expenditure model for the intended Azure solution aligns with the goal of using the correct expenditure model for migrating virtual machines to Azure. The correct answer to the question is A. Yes.
