Home > Blog > AWS Well-Architected Framework

Amazon Web Services has been revolutionizing emerging technologies for many businesses on a global scale for years now. From start-ups to enterprises, AWS solutions and trends are some of the most comprehensive and broadly adopted offerings that are attracting customers globally – including the fastest-growing start-ups, enterprises, government agencies, educational institutes and the healthcare industry as well. AWS’s Well-Architected Framework helps cloud-based solution architects build futuristic, highly efficient, and flexible infrastructure for their applications that perform to their fullest. In other words, AWS Well-Architected Framework is a structured review of existing infrastructures and a professional account of how the current design can be improved and scaled. The framework serves as the guiding post for architects to execute innovative designs and scale them according to their application requirements. The AWS Well-Architected Framework defines important principles and architectural best practises to assist cloud architects in building secure, high-performing, robust, and efficient infrastructure for their cloud applications and workloads. This blog takes you through the 6 most critical Well-Architected Framework pillars of AWS and their significance.

1. Operational Excellence

This critical pillar aims at achieving business value by consistently improvising supporting processes through expert insights. The aim is that excellent functionality is to be achieved while effectively running workloads and supporting innovative designs to lower costs, become more agile, and innovate faster. The operations team has a crucial role to play here in terms of functioning using the AWS cloud architecture design principles. Your team should ensure that the procedures align with the desired business outcomes and provide a consistent approach for creating scalable architectures. The Operations team should review and revise procedures as per the evolving scenarios and identify the workload to be assessed and reviewed. This also involves process explanation, accountability, responsibilities as well as outcomes.

2. Security

This pillar encompasses the capability to improve the protection of data, systems, and assets by leveraging the latest cloud technologies. Implementing role-based access control, data security measures to maintain confidentiality, automating security best practices, and enhanced preparedness for security events are crucial aspects to consider here. This process also includes implementing a strong identity foundation, enabling traceability, applying security at all layers and automating the security best practices. Teams also prepare for incidents by implementing incident management processes that align with the organizational requirement. Some of the approaches are running incident response simulations and using tools that automate to increase speed for detection, investigation and recovery.

3. Reliability

Reliability, one of the 6 pillars of AWS Well-Architected Framework, encompasses the precision and continuity in the functionality of a workload including the ability to operate and test the workload through its total lifecycle. In other words, it includes operating and testing a workload throughout various stages of its lifecycle. The reliability pillar summarizes design ideas, best practices, and related questions. Automatically recover from failure, test prevention techniques, expand horizontally to boost aggregate workload availability, eliminate guessing capacity, and manage change in automation are the five design concepts for cloud dependability. It also ensures the placement of foundational needs before building any system and monitors changes that need to be managed including changes to the automation, that can be tracked and reviewed. AWS Well-Architecture Review considers dependencies, as well as change management, and potential hardware component failures to achieve improved reliability.

4. Performance Efficiency

The next pillar is the increased productivity pillar which includes meeting AWS Well-Architected system requirements by making the most efficient use of computing resources. It involves maintaining productivity with evolving technologies and the changing demands play a critical role to maintain the optimal level of customer satisfaction. Performance efficiency guarantees that computing resources are used efficiently and flexibly to meet changing demands of the customers. Five design concepts for cloud performance efficiency include democratising advanced technologies, becoming global in minutes, using serverless architectures, experimenting more often, and considering mechanical sympathy. To achieve optimal performance throughout a workload, various techniques are frequently required. To boost performance, well-architected systems employ many solutions and enable various functionalities. AWS specialists design a method for selecting resources and services based on internal expertise and understanding of the cloud, as well as external resources such as case studies, blogs, and documentation like eBooks or whitepapers. Companies should establish a procedure that enables testing and benchmarking with the services that may be deployed in their respective workload. Performance efficiency allows adopting a data-driven approach, data collection to synchronize high-level design, and picking and configuring resources while developing your architecture are crucial elements here. Simultaneously, one can also leverage the advancements in the AWS Cloud to monitor, review, and enhance the overall performance is essential.

5. Cost Optimization

The cost-optimization pillar includes the technical capabilities to reduce operational costs while delivering consistent business value. The cost optimization pillar offers guidance on how to use the AWS framework’s best practises in the design, delivery, and management of AWS environments. When we talk about cost optimization, we mean a continuous process of refinement and improvement over the lifespan of a workload. The team must invest in financial management strategies to achieve any form of financial success while increasing company value realisation on the cloud. Companies must invest the time and resources required to produce capabilities in this new area of technology and utilize management plans. When you use a consumption model, you only pay for the computing resources you use, and you can increase or decrease your usage based on your business needs. A cost-optimized workload is one that makes maximum use of all resources, produces a result at the lowest feasible cost, and meets all functional criteria. By guaranteeing constant adherence to AWS Well-Architected Framework best practises and avoiding needless over-provisioning, investing the correct amount of work in a cost optimization plan, businesses may be able to more quickly enjoy the fiscal benefits of the cloud.

The following critical initiatives will help you achieve cost-cutting in the long run:

  • Executing cloud financial management,
  • A thorough analysis of costs and efficiency,
  • Eliminating expenditure on elements in a business application that doesn’t increase its competitive advantage, and
  • Picking the appropriate resources, services, and configurations for the workload.

6. Sustainability

The sustainability pillar encompasses the long-term impacts of your business operations on the environment, the economy, as well as the community. Building cloud workloads with a focus on sustainability is critical, and evaluating the effect of the services utilised should be a bigger requirement. To limit these consequences, we quantify them throughout the workload lifespan and apply design principles and best practises. Environmental implications, energy consumption, and efficiency are the most significant levers for architects to inform direct action to decrease resource utilisation. It is essential to set sustainable targets after analyzing your impact and to manage your overall impact, teams must
  • Select the AWS regions where you execute business-specific workloads
  • Optimize workload components that involve the most resources,
  • Ensure effective use of data storage and pick the most efficient hardware to manage your workload.

Implement a performance assessment method that considers deployment tests automatically and as part of the deployment process, employs visualisation techniques, and implements as a simple extension of the existing pipeline to take a data-driven approach to architecture. Companies must utilize the data acquired throughout the review process to advertise and promote the adoption of new services or resources when they become available.
