Overview

This Guidance helps customers understand the concepts of implementing a cell-based architecture. This architecture shows fault isolation between cells, which are independent replicas of the system. Customers can use this Guidance to prevent outages caused by a software bug, failed deployment, or overload, ultimately reducing the impact to end-customers.

How it works

These technical details feature an architecture diagram to illustrate how to effectively use this solution. The architecture diagram shows the key components and their interactions, providing an overview of the architecture's structure and functionality step-by-step.

Well-Architected Pillars

The architecture diagram above is an example of a Solution created with Well-Architected best practices in mind. To be fully Well-Architected, you should follow as many Well-Architected best practices as possible.

By isolating faults to business service partitions, this Guidance promotes operational excellence by ensuring that the business can continue to run services. This aligns fault isolation with individual users or sets of users. In contrast to the more traditional approach, which has users in the same failure domain of a single business system, this new approach has users in different failure domains.

Any use of cryptography is kept at a minimum with the intention of it being replaced for production use. Randomly generated API keys and JSON Web tokens are used for authentication.

This Guidance implements the Well-architected best practice of a cellular architecture.

To ensure cost optimization, only the smallest AWS Fargate container instance types are used. Deployment and workflows run on Step Functions to minimize compute cost. Monitoring uses synthetic canaries that are started only when needed.
