All-flash storage delivers the highest IOPS because solid-state drives provide significantly faster read/write operations compared to other storage types.

Workload orchestration is the best description of what the company should implement to achieve control, visibility, automation, and cost efficiency. It involves using orchestration tools to manage workloads in cloud environments, ensuring resources are used efficiently and operations are automated.

The most likely cause of the data breach is hard-coded credentials being exposed in the public repository. If the developer accidentally included database usernames and passwords in the code and pushed it to a publicly accessible repository, attackers could easily find and use them to gain unauthorized access. This is a common security oversight that leads to database compromises.
Attackers often scan public repositories for sensitive information using automated tools, making hard-coded credentials a significant risk. Best practices include using environment variables, secret management tools (e.g., AWS Secrets Manager, HashiCorp Vault), and removing credentials from source code before committing.

AWS offers technologies for running code, managing data, and integrating applications, all without managing servers. Serverless technologies feature automatic scaling, built-in high availability, and a pay-for-use billing model to increase agility and optimize costs. These technologies also eliminate infrastructure management tasks like capacity provisioning and patching, so you can focus on writing code that serves your customers.

Serverless functions are highly cost-effective because resources are consumed only when code executes. They provide rapid response times, automatically scale based on demand, and eliminate the need to manage underlying infrastructure. These characteristics make serverless technology an excellent fit for a scalable cloud-native web application.
