Strategic AWS Well-Architected Review

Introduction

Engaging in a Well-Architected Review (WAR) involves collaboration with authorized AWS partners who utilize AWS's dedicated tool. The primary goal is to ensure that the infrastructure and systems built on AWS adhere to well-architected principles. In case of any issues, consulting partners like us provide recommendations based on the five pillars: security, operational excellence, performance efficiency, reliability, and cost optimization.
This method offers a comprehensive way to consistently evaluate your architecture against industry best practices, pinpointing areas for enhancement.
Now, let's delve into a detailed example of a Well-Architected Review conducted for one of our clients.

About the Client

Our client is a one-touch healthcare solutions provider, empowering users to store health records, track fitness activities, access doctors and practices, and access health information through their Drlogy website.

Client Challenge

The client currently lacks a well-architected competency, and their architecture exhibits numerous loopholes in terms of Security, High Availability, Scalability, Reliability, Operational Excellence, and performance issues. Seeking to embrace AWS best practices, the client enlisted Signiance to conduct a comprehensive Well-Architected review of their IT environment.

Solutions

Signiance’s Well-Architected team conducted a thorough review of the customer's AWS account, focusing on the key pillars of Security, Reliability, Operational Excellence, and Performance Efficiency. Our analysis revealed several high-risk and medium-risk indicators, prompting us to provide valuable insights and remediation strategies to enhance the overall architecture.

Security

The initial evaluation highlighted a gap in baseline security practices, such as misconfigured security groups and the absence of Multi-Factor Authentication for IAM users. Our recommended remediations not only addressed these issues but also positioned the client's infrastructure as secure and well-architected, aligning with compliance standards.

Reliability

Identifying potential reliability issues in the existing infrastructure, we suggested solutions like implementing a load balancer, establishing backup schedules, and designing a robust disaster recovery setup. These measures aimed to enhance the reliability of the system, ensuring minimal impact on application and data availability.

Operational Excellence

Our assessment identified manual patching activities as a time-consuming and less secure practice. To streamline operations, we proposed automated patching solutions, efficient backup procedures, and other automation strategies. Embracing these recommendations promotes operational excellence, simplifying administration tasks and saving valuable time.

Performance Efficiency

Recognizing the absence of a comprehensive monitoring solution for key metrics like memory utilization, we recommended creating metrics, setting up alarms based on thresholds, and establishing actionable incident response procedures. These enhancements significantly boosted the overall performance of the infrastructure and application.

Additionally, we conducted an optimization check on instances, ensuring they were appropriately sized and utilizing the most suitable hardware. This holistic approach aimed to not only address immediate concerns but also lay the foundation for a resilient, efficient, and high-performing AWS environment.

Conclusion

Following the Well-Architected review, we pinpointed issues in the client's architecture and offered recommendations aligning with best practices. Implementing these suggestions has transformed the state of their architecture, ensuring it is now Well-Architected. This enhancement has seamlessly supported their business operations, earning high satisfaction from the client for Signiance's dedicated efforts and excellence.
