Traditional on-premises IT infrastructure, with its high costs and rigid limitations, struggles to meet modern demands for flexibility and scalability. Cloud computing has emerged as a transformative solution, enabling organizations to access computing resources—servers, storage, applications—over the internet, reducing costs and enhancing agility. The question, “What are three benefits of cloud computing?” highlights cost savings, scalability and elasticity, and high availability and reliability, which empower businesses to innovate without infrastructure burdens. For IT professionals, mastering cloud concepts is critical for leveraging platforms like Microsoft Azure, aligning with the AZ-900 focus on cloud fundamentals.
Key Objectives:
- Cost Efficiency: Minimize capital and operational expenses.
- Flexibility: Scale resources to meet demand dynamically.
- Reliability: Ensure continuous access to critical services.
For AZ-900 candidates, understanding cloud benefits is essential for cloud concepts and passing the exam. Study4Pass provides detailed guides on Azure fundamentals, supported by practice questions to reinforce these concepts.

Cloud Computing: A New Paradigm for IT
What is Cloud Computing?
- Definition: Cloud computing is the delivery of computing resources—such as servers, storage, databases, networking, and software—over the internet, on-demand, and on a pay-as-you-go basis.
- Characteristics:
o On-Demand Self-Service: Access resources without provider interaction.
o Scalability: Adjust resources dynamically to meet demand.
o Pay-Per-Use: Pay only for consumed resources.
o Managed Services: Providers handle maintenance, updates, and security.
- Deployment Models:
o Public, private, hybrid, and community clouds.
- Service Models:
o IaaS (e.g., Azure Virtual Machines), PaaS (e.g., Azure App Service), SaaS (e.g., Office 365).
- Example: A startup uses Azure to host a web app, scaling servers during peak traffic and paying only for usage.
Why Cloud Matters
- Agility: Rapidly deploy and scale applications.
- Cost Management: Shift from capital expenditure (CapEx) to operational expenditure (OpEx).
- Global Reach: Access resources from data centers worldwide.
- Example: A retailer uses Azure to deploy an e-commerce platform, scaling during holiday sales and ensuring uptime globally.
Azure’s Role
- Microsoft Azure: A leading cloud platform offering over 200 services, from computing to AI, built on cloud computing principles.
- Benefits Alignment: Azure leverages cost savings, scalability, and reliability to deliver value.
- Example: Azure’s auto-scaling feature adjusts resources for a gaming app, maintaining performance and minimizing costs.
AZ-900 Relevance: Questions may test cloud definitions or characteristics. Study4Pass clarifies these with diagrams and examples.
Identifying Three Major Advantages of Cloud Computing
The AZ-900 exam question asks for three benefits of cloud computing. The answers are:
Benefit 1: Cost Savings (Financial Efficiency)
- Definition: Cloud computing reduces costs by eliminating upfront capital expenses (CapEx) for hardware and shifting to a pay-as-you-go operational expenditure (OpEx) model.
- Details:
o No Hardware Investment: Avoid purchasing servers or data centers.
o Pay-Per-Use: Pay only for resources consumed (e.g., compute hours, storage).
o Reduced Maintenance: Providers handle updates, cooling, and power costs.
- Impact:
o Lowers financial barriers for startups and small businesses.
o Optimizes IT budgets for enterprises.
o Enables cost predictability with tools like Azure Cost Management.
- Example: A small business uses Azure Virtual Machines, paying $50/month for compute instead of $10,000 for a server, saving 99% on upfront costs.
- Azure Context: Azure’s pricing calculator helps estimate costs, ensuring transparency.
- AZ-900 Relevance: Cost savings is a frequently tested benefit.
Benefit 2: Scalability and Elasticity (Flexibility and Adaptability)
- Definition: Cloud computing enables organizations to scale resources up or down instantly (elasticity) and handle varying workloads efficiently (scalability).
- Details:
o Horizontal Scaling: Add or remove instances (e.g., VMs).
o Vertical Scaling: Increase or decrease resource capacity (e.g., CPU, RAM).
o Auto-Scaling: Automatically adjust based on demand (e.g., Azure Autoscale).
- Impact:
o Handles traffic spikes without over-provisioning.
o Supports growth without infrastructure redesign.
o Enhances user experience with consistent performance.
- Example: An e-commerce site on Azure scales VMs during Black Friday sales, handling 10x traffic without downtime, then scales down to save costs.
- Azure Context: Azure Load Balancer and Autoscale ensure seamless scalability.
- AZ-900 Relevance: Scalability is a core cloud advantage.
Benefit 3: High Availability and Reliability (Business Continuity)
- Definition: Cloud computing ensures services remain accessible and operational through redundancy, fault tolerance, and global data center networks.
- Details:
o Redundancy: Multiple servers and data centers prevent single points of failure.
o Failover: Automatic switching to backup resources during outages.
o SLAs: Providers guarantee uptime (e.g., Azure’s 99.9% SLA).
- Impact:
o Minimizes downtime, ensuring business continuity.
o Protects data with geo-redundant backups.
o Enhances customer trust with reliable services.
- Example: A healthcare app on Azure uses geo-redundant storage, ensuring patient data access even during a regional outage, achieving 99.99% uptime.
- Azure Context: Azure Availability Zones and Site Recovery enhance reliability.
- AZ-900 Relevance: Reliability is critical for business-focused scenarios.
Exam Answer: Three benefits of cloud computing are cost savings, scalability and elasticity, and high availability and reliability. Study4Pass flashcards emphasize these benefits for quick recall.
