Your company plans to migrate all its data and resources to Azure.
The company's migration plan states that only Platform as a Service (PaaS) solutions must be used in Azure.
You need to deploy an Azure environment that meets the company migration plan.
Solution: You create Azure virtual machines, Azure SQL databases, and Azure Storage accounts.
Does this meet the goal?

A. B.B
Platform as a service (PaaS) is a complete development and deployment environment in the cloud. PaaS includes infrastructure " servers, storage, and networking " but also middleware, development tools, business intelligence (BI) services, database management systems, and more. PaaS is designed to support the complete web application lifecycle: building, testing, deploying, managing, and updating.
However, virtual machines are examples of Infrastructure as a service (IaaS). IaaS is an instant computing infrastructure, provisioned and managed over the internet.
https://azure.microsoft.com/en-us/overview/what-is-paas/ https://azure.microsoft.com/en-us/overview/what-is-iaas/No, the solution does not meet the company's migration plan because the plan states that only Platform as a Service (PaaS) solutions should be used in Azure. Virtual machines, SQL databases, and storage accounts are all Infrastructure as a Service (IaaS) solutions.
To meet the company's migration plan, PaaS solutions such as Azure App Service, Azure Functions, Azure SQL Database, and Azure Cosmos DB should be used instead of virtual machines and SQL databases. Azure Blob Storage and Azure Queue Storage can be used instead of storage accounts to meet the PaaS requirement.
PaaS solutions are generally considered to be more scalable, cost-effective, and easier to manage than IaaS solutions, as they allow developers to focus on building and deploying applications without having to worry about the underlying infrastructure.
The solution mentioned in the question, which includes a local network gateway, can help to control the connection types between the web servers and database servers in Azure. Therefore, the solution satisfies the requirement and the correct answer is option A: Yes.
A local network gateway is an Azure resource that can be used to connect an on-premises network to an Azure virtual network over a VPN connection. It acts as the gateway between the on-premises network and the virtual network and can be used to control the connection types between the web servers and database servers.
With the use of a local network gateway, you can set up a site-to-site VPN connection between your on-premises network and the Azure virtual network, which can provide secure connectivity and help to control the types of connections between the web servers and database servers. You can configure the local network gateway to allow only specific traffic to pass through the VPN connection, such as traffic between the web servers and database servers.
Therefore, including a local network gateway in the strategy to deploy web servers and database servers to Azure would meet the requirement for controlling the connection types between the two types of servers.
