AWS Well Architected Framework - Guide to best practice

Explore the operational excellence pillar of the AWS Well-Architected Framework by monitoring systems, automating operations, and learning from failures to prepare, operate, and evolve cloud architectures.

Learn how to achieve operational excellence through four phases—organization, prepare, operate, and evolve—by defining clear roles with RACI, implementing infrastructure as code, automated deployment, monitoring, and continuous improvement.

Explore design principles of operational excellence in the AWS cloud, including infrastructure as code, small reversible changes, failure anticipation, and learning from incidents to boost resilience.

Explore the AWS well-architected security pillar, focusing on protecting information systems and assets with risk assessment, logging, monitoring, and proactive incident readiness.

Design secure AWS solutions by applying IAM least privilege, role-based access with time-limited elevation, and multifactor authentication; implement audits, logging, and encryption, plus incident response planning.

Explore the reliability pillar of the AWS well-architected framework, detailing resiliency, disaster recovery, and high availability with availability zones, cross-region replication, and infrastructure as code using CloudFormation and Systems Manager.

Discover the reliability pillar's design principles, emphasizing automated recovery and proactive CloudWatch monitoring. Use auto scaling and redundancy across availability zones with infrastructure as code for resilience.

Explore the performance efficiency pillar of the AWS Well-Architected framework, emphasizing right-sizing resources and regular evaluation to adapt as workloads evolve, including potential shifts from EC2 to serverless.

Discover how to design for performance efficiency by leveraging managed and serverless AWS services, global deployment, auto scaling, and proactive monitoring to optimize cost and user experience.

Learn the cost optimization pillar of the AWS Well-Architected framework, focusing on right sizing, auto scaling, reserve instances and spot pricing, and cost monitoring with tagging for financial management.

Explore design principles of cost optimization in cloud workloads, embracing the consumption model, measuring efficiency, tagging for cost attribution, FinOps and financial management, and AWS pricing models.

Adopt a consumption model by paying only for on-demand resources, auto scaling, and serverless computing to save costs, while monitoring with CloudWatch and cost alerts.

Measure overall efficiency to optimize cloud costs by tracking resource utilization and right-sizing instances with compute optimizer, cost explorer, and trusted advisor; set baselines, monitor with CloudWatch, and review reports.

Track and attribute AWS expenditure using cost allocation tags to categorize resources by department, project, or environment, and generate tag-based cost reports to enable data-driven optimization.

Develop cloud financial management by establishing financial accountability and transparency, creating a cloud business office and policies, and applying cost modeling, budgets, and cost allocation to align with business objectives.

Explore four pricing models in AWS—on demand, reserved instances, saving plans, and spot instances—and learn how capacity reservation and convertible RI help optimize costs.

Explore the sustainability pillar of the AWS Well-Architected Framework, focusing on measuring environmental impact, energy efficiency, and design principles for reducing cloud carbon emissions through shared responsibility.

Measure and reduce your workload's environmental impact by using the AWS customer carbon footprint tool, set sustainability goals with KPIs, and optimize resources with serverless and energy-efficient options.

Use the AWS Well-Architected tool to review workloads against the six pillars, generate improvement guidance, and view reports in a single dashboard.

Apply the AWS well-architected framework to align security, reliability, performance, efficiency, cost optimization, operational excellence, and sustainability in the AWS cloud.
