about Cloud Computing

1. Cloud Computing: Revolutionizing IT Infrastructure Cloud computing offers on-demand access to various computing resources over the internet. The global cloud market is projected to reach $1 trillion by 2027. Major providers include AWS, Azure, and GCP. This presentation will cover the advantages, disadvantages, and architectures of cloud computing with a focus on AWS.

2. Key Advantages of Cloud Computing Cost Savings Pay-as-you-go reduces CapEx and OpEx. Netflix saves millions by using AWS. Scalability Easily scale resources based on demand. AWS Auto Scaling ensures optimal performance. Reliability Built-in redundancy and failover mechanisms. AWS availability zones provide fault tolerance. Global Accessibility Access resources from anywhere. AWS global infrastructure ensures low-latency access.

3. Addressing Cloud Computing Disadvantages 1 Security Concerns Data breaches and vulnerabilities are increasing. Mitigation includes strong encryption and monitoring. 2 Vendor Lock-In Difficulty migrating between cloud providers. Use open standards and multi-cloud strategies. 3 Compliance Issues Meeting regulations like GDPR and HIPAA. Customers are responsible for their own compliance. 4 Internet Dependency Outages can disrupt access. Implement redundant connections and offline capabilities.

4. Traditional vs. Cloud IT Architecture Traditional IT On-premises data centers with high CapEx. Complex management and limited scalability. Cloud IT Virtualized resources with pay-as-you-go pricing. Simplified management and high scalability. Hybrid Cloud Combination of on-premises and cloud. Use on-premises for sensitive data. Multi-Cloud Using multiple cloud providers. Run apps on both AWS and Azure for redundancy.

5. AWS Global Infrastructure 1 Regions Geographically isolated locations. 33 AWS Regions as of 2024. 2 Availability Zones Physically separate data centers. Minimum 3 AZs per region, connected by low-latency networks. 3 Edge Locations Global network of caching servers. 400+ locations globally for content delivery.

6. Core Components of AWS Architecture Compute EC2 for virtual servers, Lambda for serverless, ECS and EKS for containers. Storage S3 for object storage, EBS for block storage, EFS for network file systems. Database RDS for relational databases, DynamoDB for NoSQL, Aurora for MySQL and PostgreSQL. Networking VPC for isolated networks, Direct Connect for dedicated connections, Route 53 for DNS.

7. AWS Services: Compute Options Amazon EC2 Scalable virtual servers for web and app servers. Cost varies. AWS Lambda Serverless compute for event-driven apps. Pay per request. Amazon ECS Container orchestration service for Docker. Cost varies. AWS EKS Managed Kubernetes for scaling containerized apps. Cost varies.

8. AWS Services: Storage and Databases Amazon S3 Object storage for images and backups. Pay per GB stored. Amazon EBS Block storage for EC2 instances. Pay per GB provisioned. Amazon RDS Managed relational database service. Cost varies. Amazon DynamoDB NoSQL database. Pay per read/write capacity.

9. AWS Services: Networking and Security Amazon VPC Logically isolated section of the AWS Cloud. Enables you to launch AWS resources in a virtual network that you define. AWS Direct Connect Establishes a dedicated network connection from your premises to AWS. Increases bandwidth and reduces latency. AWS IAM Enables you to manage access to AWS services and resources securely. Define and control user permissions. AWS Shield Provides DDoS protection for your AWS resources. Safeguards applications running on AWS.

10. Conclusion: Cloud Computing with AWS 1 Advantages Cloud computing offers cost savings and scalability. 2 Comprehensive Services AWS provides a wide range of services. 3 Understanding Cloud architecture is essential. 4 Future Trends Serverless and AI/ML integration are key trends.
