Microsoft Certified: Azure Fundamentals (AZ-900) Practice Exam

What type of service is Azure Blob Storage categorized as?

1. Database as a Service (DBaaS)

2. Infrastructure as a Service (IaaS)

3. Platform as a Service (PaaS)

4. Storage as a Service (StaaS)

The correct answer is: Storage as a Service (StaaS)

Azure Blob Storage is categorized as Storage as a Service (StaaS) because it provides scalable, durable, and highly available object storage for unstructured data. The service is designed to handle a vast amount of data, offering features such as automatic backups, replication options for redundancy, and easy accessibility through REST APIs. This categorization highlights how Azure Blob Storage focuses specifically on offering storage capabilities, allowing users to store and retrieve any amount of data at any time from anywhere on the web. It abstracts the underlying infrastructure management, which aligns with the StaaS model. In contrast, Database as a Service (DBaaS) involves managed database services, Infrastructure as a Service (IaaS) provides virtualized computing resources over the internet, and Platform as a Service (PaaS) delivers a platform allowing developers to build applications without managing the underlying infrastructure. Each of these options serves different purposes in cloud computing, whereas Azure Blob Storage specifically targets the needs of data storage.
