CCoE Architecture Design

Based on Huawei's cloud architecture design experience and industry best practices, we have developed Well-Architected Framework (WAF) to provide a set of cloud architecture design principles and best practices for architects, software engineers, and O&M engineers. The purpose is to help enterprises design, build, and operate resilient, secure, high-performance, and cost-effective application systems on the cloud.

WAF covers five pillars, as shown in the following figure.

• Resilience

  Resilience focuses on the continuous availability and reliability of systems in response to faults, pressure, and changes. It uses technologies and processes such as redundant components, comprehensive fault detection, overload control, and fast fault recovery to ensure that application systems can quickly recover from various faults and continue to provide services even in unexpected events or heavy loads. Enterprises need to plan and implement failover as well as backup and recovery policies, and regularly perform disaster recovery drills to verify the resilience of application systems.

• Security

  The security pillar is dedicated to protecting the confidentiality, integrity, and availability of information, systems, and assets. It covers application security, data security and privacy protection, infrastructure security, and security operations. Enterprises should use strong security policies, including identity authentication and authorization, encryption of data transmission and storage, network security measures, and continuous monitoring and auditing to detect and handle security threats in a timely manner.

• Performance efficiency

  The performance efficiency pillar focuses on how to efficiently use cloud resources to meet system performance requirements and adapt to business changes. It emphasizes performance planning, modeling, analysis, and optimization to ensure that the system can maintain optimal performance under different loads. Enterprises need to continuously monitor system performance metrics, optimize applications and infrastructure configurations, use technologies such as caching to improve response speed, and periodically evaluate and adjust architecture design.

• Cost optimization

  Cost optimization aims to improve the cost-effectiveness of cloud resources and eliminate unnecessary overhead and resource waste. It encourages enterprises to allocate resources cost-effectively by optimizing billing modes, resources, and architectures. Enterprises should establish a continuous cost operational model to keep analyzing and monitoring cloud costs and identify cost-saving opportunities. This can avoid over-allocated or idle resources and improve return on investment (ROI) and financial efficiency.

• Operational excellence

  Operational excellence focuses on efficiently operating and monitoring systems, continuously improving processes, and delivering business value. It emphasizes DevOps, infrastructure as code, automated deployment, testing and verification, and automated O&M tasks, as well as a setup of comprehensive monitoring, logging, and alarm reporting mechanism. With carefully designed operation processes, change management, and continuous improvement methods, enterprises can quickly respond to changes, reduce errors, improve team collaboration efficiency, and ensure the achievement of business objectives.
