Architecting on AWS:Best PracticesAsha Chakrabarty, AWS Solutions Architect

The AWS Well-Architected Framework

• Increase awareness of architectural best practices• Addresses foundational areas that are often

neglected • Consistent approach to evaluating architectures• Composed of:

• Pillars• Design principles• Questions

Pillars of Well-Architected

Security Reliability Performance Efficiency

Cost Optimization

Security

• The ability to protect information, systems, and assets while delivering business value through risk assessments and mitigation strategies.

• Data protection• Privilege management• Infrastructure protection• Detective controls

Security is shared between AWS and you

Customers have their choice of security configurations IN the Cloud

AWS is responsible for the security OFthe Cloud

Key AWS Services for Security• Data Protection:

- Elastic Load Balancer- Amazon EBS, Amazon S3, Amazon RDS, AWS KMS

• Privilege Management: - AWS IAM, MFA

• Infrastructure Protection: - Amazon VPC

• Detective Controls: - AWS CloudTrail- Amazon CloudWatch- AWS Config

Reliability

• The ability of a system to recover from infrastructure or service failures, dynamically acquire computing resources to meet demand, and mitigate disruptions such as misconfigurations or transient network issues.

• Foundations• Change management• Failure management

Key AWS Services for Reliability• Foundations:

- AWS IAM- Amazon VPC

• Change Management: - AWS CloudTrail- AWS Config

• Failure Management: - AWS CloudFormation

Performance Efficiency

• The ability to use computing resources efficiently to meet system requirements, and to maintain that efficiency as demand changes and technologies evolve.

• Compute• Storage• Database• Go Global

Key AWS Services for Performance Efficiency• Compute: Auto Scaling • Storage:

- Amazon EBS- Amazon S3- Amazon Glacier

• Database: - Amazon RDS - Amazon DynamoDB

• Go Global: - Global presence with regions spanning the globe- Amazon CloudFront

Cost Optimization

• The ability to avoid or eliminate unneeded cost or suboptimal resources.

• Matched supply and demand • Cost-effective resources • Expenditure awareness• Optimizing over time

Key AWS Services for Cost Optimization• Matched supply and demand: Auto Scaling • Cost-effective resources:

- Reserved Instances (RI): prepaid capacity to reduce your cost- AWS Trusted Advisor: inspect your AWS environment and find

opportunities to save money. • Expenditure awareness:

- Amazon CloudWatch alarms - Amazon Simple Notification Service (SNS) notifications

• Optimizing over time: - The AWS Blog and What’s New section on the AWS website - AWS Trusted Advisor

Design Principles

• The Well-Architected Framework has identified a set of design principles to facilitate good design in the cloud:

• General design principles• Pillar-specific design principles

Automate responses to security events: Monitor and automatically trigger responses to event-driven, or condition-driven, alerts.

Questions

• A set of questions you can use to evaluate how well an architecture is aligned to AWS best practices.

Next Steps

• Read the whitepaper• Apply it to your architectures• Schedule time for an architectural review with

your Solutions Architect
