Microsoft Azure Well-Architected Framework
The Azure Well-Architected Framework is a set of guiding tenets that can be used to improve the quality of a workload. The framework consists of five pillars of architectural excellence:
Incorporating these pillars helps produce a high quality, stable, and efficient cloud architecture:
|Reliability||The ability of a system to recover from failures and continue to function.|
|Security||Protecting applications and data from threats.|
|Cost Optimization||Managing costs to maximize the value delivered.|
|Operational Excellence||Operations processes that keep a system running in production.|
|Performance Efficiency||The ability of a system to adapt to changes in load.|
Reference the following video about how to architect successful workloads on Azure with the Well-Architected Framework:
The following diagram gives a high-level overview of the Azure Well-Architected Framework:
In the center, is the Well-Architected Framework, which includes the five pillars of architectural excellence. Surrounding the Well-Architected Framework are six supporting elements:
- Azure Well-Architected Review
- Azure Advisor
- Partners, Support, and Services Offers
- Reference Architectures
- Design Principles
Assess your workload
To assess your workload using the tenets found in the Microsoft Azure Well-Architected Framework, see the Microsoft Azure Well-Architected Review.
We also recommend you use Azure Advisor and Advisor Score to identify and prioritize opportunities to improve the posture of your workloads. Both services are free to all Azure users and align to the five pillars of the Well-Architected Framework:
Azure Advisor is a personalized cloud consultant that helps you follow best practices to optimize your Azure deployments. It analyzes your resource configuration and usage telemetry. It recommends solutions that can help you improve the reliability, security, cost effectiveness, performance, and operational excellence of your Azure resources. Learn more about Azure Advisor.
Advisor Score is a core feature of Azure Advisor that aggregates Advisor recommendations into a simple, actionable score. This score enables you to tell at a glance if you're taking the necessary steps to build reliable, secure, and cost-efficient solutions, and to prioritize the actions that will yield the biggest improvement to the posture of your workloads. The Advisor score consists of an overall score, which can be further broken down into five category scores corresponding to each of the Well-Architected pillars. Learn more about Advisor Score.
A reliable workload is one that is both resilient and available. Resiliency is the ability of the system to recover from failures and continue to function. The goal of resiliency is to return the application to a fully functioning state after a failure occurs. Availability is whether your users can access your workload when they need to.
For more information about resiliency, reference the following video that will show you how to start improving the reliability of your Azure workloads:
The following topics offer guidance on designing and improving reliable Azure applications:
- Designing reliable Azure applications
- Design patterns for resiliency
- Best practices:
For an overview of reliability principles, reference Principles of the reliability pillar.
Think about security throughout the entire lifecycle of an application, from design and implementation to deployment and operations. The Azure platform provides protections against various threats, such as network intrusion and DDoS attacks. But you still need to build security into your application and into your DevOps processes.
Ask the right questions about secure application development on Azure by referencing the following video:
Consider the following broad security areas:
- Identity management
- Protect your infrastructure
- Application security
- Data sovereignty and encryption
- Security resources
For more information, reference Overview of the security pillar.
When you're designing a cloud solution, focus on generating incremental value early. Apply the principles of Build-Measure-Learn, to accelerate your time to market while avoiding capital-intensive solutions.
For more information, reference Cost optimization and the following video on how to start optimizing your Azure costs:
The following topics offer cost optimization guidance as you develop the Well-Architected Framework for your workload:
- Review cost principles
- Develop a cost model
- Create budgets and alerts
- Review the cost optimization checklist
For a high-level overview, reference Overview of the cost optimization pillar.
Operational excellence covers the operations and processes that keep an application running in production. Deployments must be reliable and predictable. Automate deployments to reduce the chance of human error. Fast and routine deployment processes won't slow down the release of new features or bug fixes. Equally important, you must quickly roll back or roll forward if an update has problems.
For more information, reference the following video about bringing security into your DevOps practice on Azure:
Operational excellence guidance
The following topics provide guidance on designing and implementing DevOps practices for your Azure workload:
- Design patterns for operational excellence
- Best practices: Monitoring and diagnostics
For a high-level summary, reference Overview of the operational excellence pillar.
Performance efficiency is the ability of your workload to scale to meet the demands placed on it by users in an efficient manner. The main ways to achieve performance efficiency include using scaling appropriately and implementing PaaS offerings that have scaling built in.
For more information, watch Performance Efficiency: Fast & Furious: Optimizing for Quick and Reliable VM Deployments.
