The Well-Architected Framework (WAF) is a set of best practices for designing and operating reliable, secure, efficient, and cost-effective systems in the cloud.
It was developed by Amazon Web Services (AWS) and is intended to help teams build and maintain cloud systems that meet the needs of their organisation. In this blog article, we explore its advantages for business operations, and the opportunities it offers when used in conjunction with DevOps.
The six pillars of the Well-Architected Framework are:
- Operational Excellence
- Performance Efficiency
- Cost Optimisation and
How does the WAF work?
For each area, the WAF provides a set of design and management analyses that can be used to evaluate the implementation and operation of cloud platforms. AWS maintains the WAF as a living document that evolves in alignment with cloud technologies and best practices.
The framework can be combined with DevOps practices to help design and operate cloud systems that are reliable, secure, efficient, and cost-effective.
Aligning the Well-Architected Framework and DevOps Processes
DevOps refers to a set of practices and tools to improve the collaboration between development and operations teams, with the goal of delivering software more quickly and reliably. It emphasises continuous integration, delivery, and deployment of software, as well as the use of automation for managing the building, testing, and release processes.
The Well-Architected Framework can be used to guide the design and operation of the infrastructure and systems that support a DevOps environment. It provides various best practices and design principles for building and operating cloud systems, as well as a set of review questions for the evaluation of a system.
By using the WAF in conjunction with DevOps practices, organisations can build and operate state-of-the-art cloud systems while, at the same time, delivering software more quickly and reliably.
Hence, Aligning DevOps processes with the Well-Architected Framework is key for creating reliable, secure, efficient, and cost-effective applications. This approach embeds best practices to ensure businesses are following standards in areas such as risk management, security, resilience, scalability, performance efficiency, operational excellence, and cost optimisation. By adhering to WAF practices throughout development and deployment, businesses can ensure they are implementing application platforms without jeopardising security or performance.
Four reasons why companies should use the Well-Architected Framework
Using the Well-Architected Framework comes with various business advantages:
- Improved reliability: By following WAF practices, companies can reduce failure and outage risks while improving the overall reliability of their systems.
- Enhanced security: The WAF provides a consolidated approach to securing cloud platforms – at network, user, application and data level.
- Increased efficiency: A workload performance analysis helps to ensure an ideal distribution of work among resources.
- Cost optimisation: The budget on cloud implementation is used in the most cost-effective way and in line with business requirements.
Well-Architected Framework: a new level of cloud security
The Well-Architected Framework helps companies reduce the risk of security breaches and protect sensitive data with its best practices for securing cloud systems. The security best practices include:
- Implementing least privilege: Ensuring that users' and processes' access rights are limited to the minimum necessary to complete their tasks.
- Enabling traceability: Creating a record of all system changes so any issues can be traced back to their source.
- Protecting against network threats: Implementing network security measures such as firewalls and intrusion detection/prevention systems to ward off any network-based threats.
- Encrypting data at rest and in transit: Protecting data from unauthorised access by encrypting it when stored or transmitted.
By following these and other best practices of the framework, businesses can improve the security of their cloud systems significantly.
Cloud Adoption Framework versus Well-Architected Framework
Cloud Adoption Framework (CAF) is a set of best practices intended to guide organisations in planning and implementing their transition to cloud services – from defining the business drivers, to creating a technology roadmap through to preparing teams for the move to the cloud.
Both the Cloud Adoption Framework and the Well-Architected Framework are valuable tools for organisations looking to adopt and use cloud services effectively, and yet they differ: While the CAF covers the people, process and technology aspects of moving to the cloud, the Well-Architected Framework focuses more specifically on optimising, securing and operating workloads in the cloud.
The CAF provides both technical and organisational perspectives, while the WAF provides guidance on designing and operating cloud systems in a way that both meets the needs of the organisation and is aligned with AWS best practices.
And yet they have one common goal: to help companies successfully implement, operate and evolve their cloud computing infrastructure.
