The Well-Architected Framework

1. What are the pillars?

The Well-Architected Framework is a collection of best practices and guidelines for designing and running cloud-based systems and applications. It is mainly developed by AWS, but also adapted by Azure. The framework consists of five pillars of architectural excellence: reliability, security, cost optimization, operational excellence, and performance efficiency. The framework helps organizations understand the trade-offs and decisions they need to make when using the cloud, and provides guidance for making improvements.

The five pillars are:

• 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.
