UNIT-III: Amazon Web Services (AWS) Introduction
● Getting Started with AWS: Creating an account, using the
Management Console, understanding Regions and Availability
Zones.
● AWS Compute: Services for processing power. Amazon EC2
provides virtual servers.
● AWS Storage: Services for storing data. Amazon S3 for object
storage, Amazon EBS for block storage for EC2, Amazon Glacier
for archiving.
● AWS Networking: Services for networking cloud resources.
Amazon VPC for isolated private networks, Route 53 for DNS,
Elastic Load Balancing (ELB) for distributing traffic.
● AWS Security:
○ Shared Responsibility Model: AWS secures the cloud
hardware, you secure your data and access in the cloud.
○ Identity and Access Management (IAM): Manages user
access to AWS services using permissions based on the
"least privilege" principle.
● AWS Database Options: Amazon RDS for relational databases,
Amazon DynamoDB for NoSQL, Amazon Redshift for data
warehousing.
● AWS Elasticity: Automatically scaling resources based on
demand. Auto Scaling service helps achieve this.
● Management Tools: AWS CloudWatch for monitoring, AWS
CloudFormation for Infrastructure as Code, AWS CLI for
command-line management.
4.AWS. Introduction to System Design: Planning how
application components work together on AWS.
● AWS Essentials Review: Recap of core services.
● System Design for High Availability (HA): Designing systems
that stay operational if components fail using multiple
Availability Zones, ELB, and Auto Scaling.
● Automation: Automating tasks like deployment and
configuration using tools like CloudFormation and CodeDeploy.
● Serverless Architectures: Running applications without
managing servers. AWS Lambda runs code based on events,
and you pay only for compute time.
● Well-Architected Best Practices (The 5 Pillars): A framework
for building secure, efficient, and cost-effective architectures.
○ Security: Protecting data and systems using services like
IAM and VPC Security Groups.
○ Reliability: Recovering from disruptions and scaling to
meet demand using Multi-AZ and Auto Scaling.
○ Performance Efficiency: Using resources efficiently and
maintaining efficiency as demand changes using
appropriate EC2 instance types and Auto Scaling.
○ Cost Optimization: Avoiding unneeded costs using
Reserved Instances and Cost Explorer.
○ Operational Excellence: Running n monitoring systems n
improving processes using CloudFormation n CloudWatch.
● Cost Optimization and Deployment: Strategies to reduce
costs and plan application deployments.
● Design Patterns and Sample Architectures: Common
solutions for specific problems using various AWS services.
UNIT-V: Cloud Security Tools and Technologies
● Cloud Security Tools and Technologies: Tools to secure data
in private and public clouds.
○ Encryption: Protecting data using services like AWS KMS.
○ Identity and Access Management (IAM): Controlling who
can access what.
○ VPNs & Direct Connect: Securely connecting on-premises
networks to AWS.
○ Firewalls: Network security groups and AWS WAF to filter
traffic.
○ Intrusion Detection/Prevention Systems (IDS/IPS):
Monitoring for malicious activities (e.g., AWS GuardDuty).
○ Data Loss Prevention (DLP): Preventing sensitive data
from leaving the cloud (e.g., Amazon Macie).
○ Security Monitoring & Logging: Tools like AWS CloudTrail
and CloudWatch.
● Security Concerns: Data breaches, misconfigured cloud
settings, insecure APIs, account hijacking, insider threats.
● Compliance & Auditing: Meeting regulations like HIPAA and
GDPR. AWS provides certifications.
● Legal Issues and Aspects: Data sovereignty, data privacy
regulations, SLAs.
● Multi-tenancy Issues: Security risks in environments where
multiple customers share infrastructure if isolation is not
properly implemented.
● Cloud Simulation: Modeling and testing cloud environments
before deployment to understand performance, cost, and
vulnerabilities.
