Overview of Cloud Computing and Introduction to Microsoft Azure

Overview of Cloud Computing

Cloud computing is a technology that enables individuals and businesses to access computing resources such as servers, storage, databases, networking, software, and analytics over the internet. Instead of maintaining physical hardware and infrastructure, users can leverage cloud services provided by companies like Microsoft Azure, Amazon Web Services (AWS), and Google Cloud Platform (GCP) on a pay-as-you-go basis.

Key Characteristics of Cloud Computing

1. On-Demand Self-Service – Users can provision resources like servers and storage without human intervention.
2. Broad Network Access – Services are accessible over the internet from anywhere.
3. Resource Pooling – Cloud providers allocate resources dynamically across multiple customers.
4. Scalability & Elasticity – Resources can scale up or down automatically based on demand.
5. Pay-as-You-Go Pricing – Users only pay for the resources they consume.

Types of Cloud Computing Services

Cloud computing services are categorized into three main models:

1.Infrastructure as a Service (IaaS)

• Provides virtualized computing resources over the internet.
• Examples: Azure Virtual Machines, AWS EC2, Google Compute Engine.

2.Platform as a Service (PaaS)

• Offers a development environment without managing underlying infrastructure.
• Examples: Azure App Services, AWS Elastic Beanstalk, Google App Engine.

3.Software as a Service (SaaS)

• Delivers software applications over the internet on a subscription basis.
• Examples: Microsoft 365, Google Workspace, Salesforce.

Types of Cloud Deployments

1. Public Cloud – Services are provided by third-party providers (Azure, AWS, GCP).
2. Private Cloud – Cloud infrastructure is dedicated to a single organization.
3. Hybrid Cloud – A combination of public and private clouds.
4. Multi-Cloud – Usage of multiple cloud providers for different services.

Benefits of Cloud Computing

• Cost-Effective – No upfront hardware costs.
• High Availability & Reliability – Redundant systems ensure minimal downtime.
• Security & Compliance – Cloud providers implement advanced security measures.
• Global Reach – Services are available from anywhere with an internet connection.
• Automatic Updates – Software and infrastructure updates are managed by the provider.

Popular Cloud Computing Providers

1. Microsoft Azure – Offers a wide range of cloud services with deep integration with Microsoft products.
2. Amazon Web Services (AWS) – The largest cloud provider with extensive global infrastructure.
3. Google Cloud Platform (GCP) – Known for AI, machine learning, and data analytics services.
4. IBM Cloud – Focuses on hybrid cloud solutions and AI-powered cloud services.
5. Oracle Cloud – Popular for enterprise database and SaaS applications.

Introduction to Microsoft Azure

Microsoft Azure is a cloud computing platform and service provided by Microsoft, offering a wide range of cloud services, including computing, storage, networking, databases, AI, and security. It enables businesses, developers, and IT professionals to build, deploy, and manage applications and infrastructure efficiently across Microsoft’s global data centers.

What is Microsoft Azure?

Azure is a flexible and scalable cloud platform that provides solutions for:

• Infrastructure as a Service (IaaS) – Virtual machines, networking, and storage.
• Platform as a Service (PaaS) – App hosting, serverless computing, and container services.
• Software as a Service (SaaS) – Cloud-based software applications like Microsoft 365.

Azure supports multiple programming languages, frameworks, and operating systems, making it a preferred choice for enterprises, startups, and developers.
