ANS-C01 Study Notes
-
AWS Architecture Best Practices
- Design for scalability and availability. Employ multiple Availability Zones (AZs) to prevent single points of failure.
- Implement fault tolerance. Design systems with redundant components and failover mechanisms.
- Favor stateless architectures for easier scaling and improved fault tolerance.
- Adopt a modular design approach. Design individual components and services and build applications by assembling these modules.
- Implement a well-defined and documented architecture. Clear communication helps team members and stakeholders understand the system easily.
- Employ the principle of least privilege. Provide users with only the necessary permissions to the system.
- Prioritize security best practices throughout the AWS architecture design.
- Design the architecture for monitoring and logging. This allows for quick detection of performance bottlenecks and other issues.
- Avoid vendor lock-in. Design the architecture with future upgrades, compatibility, and the possibility of switching to other platforms in mind.
-
AWS Services Overview
- Compute: EC2 (Elastic Compute Cloud) provides virtual servers. Lambda offers serverless computing.
- Storage: S3 (Simple Storage Service) provides object storage. EBS (Elastic Block Store) provides block storage.
- Databases: RDS (Relational Database Service) provides managed database instances. DynamoDB offers a NoSQL database service.
- Networking: VPC (Virtual Private Cloud) allows you to create a secure virtual network. Route 53 provides domain name systems.
- Management & Monitoring: CloudWatch provides monitoring and logging capabilities. IAM (Identity and Access Management) manages user access to AWS resources.
- Security: Security Hub automates security checks and enforcement. KMS (Key Management Service) enables the encryption of sensitive data.
-
Designing Scalable Applications
- Identify potential scaling points in an application. Understand where the workload is concentrated.
- Employ autoscaling groups. Automatically adjust the number of EC2 instances based on demand.
- Use serverless technologies like AWS Lambda. Automatically scale up to meet demand.
- Implement caching mechanisms. Cache frequently accessed data to reduce database load.
- Break down applications into smaller, independent services. Each component scales independently, allowing for efficient use of resources.
-
Security In AWS
- Leverage IAM for granular control over access.
- Encrypt data in transit and at rest. Use KMS for managing encryption keys.
- Configure strong passwords and multi-factor authentication (MFA).
- Implement regular security audits. Verify access controls and update configurations as needed.
- Follow the principle of least privilege. Grant users only necessary permissions.
- Regularly update software and security patches.
- Apply threat modeling techniques. Identify potential threats and vulnerabilities early.
- Implement secure configurations for AWS services used in the application. This includes using secure settings, access control lists, and restrictions.
-
Cost Optimization Strategies
- Adopt a pay-as-you-go model approach and optimize configurations. Carefully examine services for usage and possible cost reductions.
- Use Reserved Instances to get discounts on predictable workloads.
- Utilize Spot Instances for cost-effective on-demand resources, but be prepared for potential interruptions.
- Optimize the use of Amazon EC2 instances. Consider using instances with better cost-performance options to cut costs.
- Optimize storage costs by using cost-effective storage tiers or using different storage types based on the needs. Leverage lifecycle policies.
- Monitor and analyse AWS cost usage. Use reporting features to track and identify areas for optimization and potential savings.
- Turn off unused services and resources. Regularly review and remove unused AWS services, resources, and associated billing.
- Employ rightsizing strategies. Match the compute resources to the actual workload. Don't over-provision.
- Leverage AWS Savings Plans for predictable workloads. This feature delivers long-term volume discounts, maximizing cost-effectiveness.
