The recommended solution for scanning application code that meets development requirements is Azure DevTest Labs. This service is specifically designed to enable developers and testers to quickly create environments in Azure. It supports continuous integration and delivery pipelines, allowing teams to automate the process of building, testing, and deploying applications. In the context of code scanning, it provides tools and integration with other Azure services that help ensure that application code is tested for vulnerabilities, compliance, and quality before being moved to production.
By using Azure DevTest Labs, teams can establish control over their development and testing environments, implement best practices in security, and integrate scanning tools seamlessly into their workflows. This makes it particularly suitable for organizations looking to maintain a secure software development lifecycle (SDLC) while meeting their specific development requirements. In contrast, while the other options have their own unique benefits and use cases, they are not tailored specifically for the purpose of application code scanning in the context required.
