Cloud Computing

• Definition: Use of remote servers on the internet to perform tasks.
• Example: Hosting applications or databases on another company's servers.
• Cloud Provider: Company providing cloud services.
• Benefits of Cloud Computing:
  • Reduces initial investment in hardware.
  • Allows for focus on application development, not server management.
  • Offers scalability and management by the cloud provider.
  • Pay-as-you-go pricing: Pay only for the time servers are used.

Cloud Models

Deployment Models

1. Public Cloud: Shared infrastructure among multiple clients.
2. Private Cloud: Exclusive infrastructure for a single client.
3. Hybrid Cloud: Combination of public and private clouds.

Service Models

1. Infrastructure as a Service (IaaS): Provides virtual machines and storage capabilities.
2. Platform as a Service (PaaS): Offers a platform for developers to build applications without managing servers.
3. Software as a Service (SaaS): Software hosted and managed by the provider (e.g., Google Drive, Netflix).

Top Cloud Providers

• AWS (Amazon Web Services): Largest market share.
• Microsoft Azure: Second-largest, growing rapidly.
• Google Cloud: Third position.
• Azure advantages include cheaper pricing for Microsoft products and a high percentage of Fortune 500 companies using it.

Microsoft Azure Overview

• Azure is a cloud service developed and managed by Microsoft.
• Offers a variety of services, including IaaS, PaaS, and SaaS.
• Operates on a pay-as-you-go model.

Azure Core Architecture

• Core Components:
  • Azure Resource Manager: Mediates interactions with Azure resources.
  • Access Methods:
    • Azure Portal (GUI)
    • Azure PowerShell (Command Line)
    • Azure CLI (Command Line)
    • REST APIs

Resource Groups

• Group related Azure resources for management and organization.

Core Azure Services

Core Services Overview

1. Compute Services:

   • Virtual Machines: IaaS offering.
   • Function Apps: PaaS for back-end processing without OS management.
   • App Services: PaaS for deploying web applications.
   • Kubernetes Service: Manages containerized applications.

2. Networking Services:

   • Virtual Networks: Isolated environments for Azure resources.
   • Load Balancers: Distributes incoming network traffic.
   • DNS Zones: Routes domain names to Azure resources.
   • Content Delivery Network (CDN): Caches static content for faster access.

3. Storage Services:

   • Blob Storage: Stores unstructured data.
   • File Storage: Shared file storage for multiple VMs.
   • Table Storage: NoSQL database for structured data.
   • Queue Storage: Message queue for decoupled processing.
   • Data Lake Storage: Storage for big data analytics.
   • Data Box: Physical device for transferring large amounts of data to Azure.

4. Database and Analytics Services:

   • SQL Database: Managed relational database.
   • Cosmos DB: Globally distributed NoSQL database.
   • Data Factory: ETL service for data processing.
   • Event Hubs: Event ingestion service for big data.
   • Data Lake Analytics: Data processing service for large datasets.

5. AI and Machine Learning Services:

   • Cognitive Services: Pre-trained models for various tasks (e.g., vision, language).
   • Bot Services: AI chatbots for customer service.
   • Machine Learning Studio: No-code/low-code environment for building ML models.

6. Identity Services:

   • Azure Active Directory: Identity management service for users and groups.

Management Tools in Azure

1. Log Analytics: Monitoring and logging service for Azure resources.
2. Cost Management and Billing: Tool for managing costs and budgets in Azure.
3. Automation Account: Automates resource deployments and management.
4. Metrics: Visualizes resource performance and usage.

Hands-On Demonstration

• Created a resource group and deployed a Linux VM.
• Hosted a website that uploads files to Azure Blob Storage.
• Configured a MySQL database on Azure.
• Set up an Azure App Service to host the website.
