What network connectivity solution should you recommend for the Azure Storage account that will host App1 data, ensuring security and compliance?

Recommending a private endpoint for the Azure Storage account that will host App1 data is a wise choice due to several essential factors related to security and compliance. Private endpoints enable secure, private connectivity to Azure services, utilizing the Microsoft backbone network. This means traffic between the storage account and the resource accessing it remains internal to the Azure network, without exposure to the public internet.

Using a private endpoint ensures that data in transit remains protected from potential external threats, aligning well with governance and compliance standards that many organizations must adhere to. It allows for more granular access controls, as network administrators can configure Virtual Network/Subnet access restrictions to specifically designate which resources can connect to the storage account.

In addition to enhanced security, using a private endpoint facilitates improved performance by providing lower latency and greater reliability, as it bypasses the broader internet routing paths that can introduce unpredicted delays and risks. This solution adheres to best practices in cloud security, providing necessary isolation from potential unauthorized access.

Although other options like Microsoft peering, Azure public peering, and service endpoints still offer connectivity to Azure resources, they do not provide the same level of isolation and security as a private endpoint, as they may still expose data to the public internet or allow broader access than desired
