Explore the essentials of cloud computing and compare the key services and strengths of AWS, Azure, and Google Cloud. Perfect for those new to the cloud or considering which platform best fits various needs.
Which of the following is a main advantage of using cloud computing platforms like AWS, Azure, or Google Cloud for a growing business?
Explanation: Cloud computing offers scalability and the ability to rent resources as needed, making it easier for businesses to grow or adjust to changing demand. Fixed hardware costs are associated with traditional infrastructure, not the cloud. Cloud platforms encourage flexible storage options, including remote and local. Manual server maintenance is minimal with cloud services compared to on-premises setups.
If a developer needs to deploy a web application, which key cloud service would be most commonly used across AWS, Azure, and Google Cloud for hosting applications?
Explanation: Virtual Machines allow users to run and manage operating systems and applications, making them the basic offering for application hosting on any cloud platform. Object Storage is mainly used for files and unstructured data. Content Delivery Networks speed up content distribution, not app hosting. Quantum Computing Nodes are specialized and not standard for general web apps.
Which option correctly matches these compute services to their respective platforms: EC2 for AWS, Virtual Machines for Azure, and Compute Engine for Google Cloud?
Explanation: EC2 (AWS), Virtual Machines (Azure), and Compute Engine (Google Cloud) are the standard compute service names for each respective platform. The other examples list different types of services such as storage or analytics, not core compute.
What is the primary advantage of a multi-cloud strategy, where a company uses more than one cloud provider like AWS and Azure?
Explanation: A multi-cloud strategy helps avoid reliance on just one provider, potentially increasing flexibility and resilience. It cannot eliminate all security risks, reduce internet needs, or guarantee zero downtime, though it can help minimize risks related to provider outages.
A retail company wants to recommend products to customers in real time through their online store. Which type of cloud service would best support building this recommendation feature?
Explanation: Machine Learning as a Service provides tools and infrastructure for building intelligent recommendation systems. IoT platforms are for connected devices, backup and archiving tools handle data protection, and Blockchain as a Service is for distributed ledger uses, not customer recommendations.
