This Guidance shows how you can use AWS machine learning (ML) services to return semantically similar images to an article. It also uses artificial intelligence (AI) services and pre-trained large language models (LLMs) to summarize the article and extract key points, which become a search input parameter for an Amazon OpenSearch Service index. A search of the index will then return the most relevant images along with key points from the article, such as celebrity names, contributing to quicker discoverability of images from the article.

Well-Architected Pillars

The AWS Well-Architected Framework helps you understand the pros and cons of the decisions you make when building systems in the cloud. The six pillars of the Framework allow you to learn architectural best practices for designing and operating reliable, secure, efficient, cost-effective, and sustainable systems. Using the AWS Well-Architected Tool, available at no charge in the AWS Management Console, you can review your workloads against these best practices by answering a set of questions for each pillar.

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.

  • CloudWatch and X-Ray provide visibility into the health of the application and allow you to identify where there may be issues through correlation IDs provided by X-Ray. X-Ray integrates with many of the AWS services in this Guidance and can surface where in the chain of events the issue occurred.

    Additionally, CloudWatch offers monitoring dashboards and sets thresholds against metrics to alert you when there are issues. Many of the services can also write logs to CloudWatch for post-analysis of an issue. CloudWatch automatically monitors the infrastructure and enables build automation into the workflows to notify you of operational issues.

  • To access the APIs, Amazon Cognito must provide authentication. Without authenticating, an individual cannot access any of the backend services. Amazon Cognito is scalable to set up and has native integration with API Gateway. API Gateway automatically delivers protection from distributed denial-of-service (DDoS) attacks for the backend services.

    AWS Identity and Access Management (IAM) allows you to provide granular, least privilege access to resources. IAM restricts access across the Guidance by applying policies to Lambda to confirm it can only invoke certain APIs explicitly provided in the IAM policy.

  • CloudFront allows you to reduce the latency of page load times, so editors can access the system from multiple geographies. CloudFront serves images back to the editor and allows the editor to cache images closer to their location, reducing latency of larger files.

    Read the Reliability whitepaper 
  • CloudFront uses a global network of 450+ Points of Presence, which provides low latency and faster HTTPS connections. Lambda allows the user to optimize how much memory is required to run the function and can scale out to thousands of requests per second within seconds. Amazon OpenSearch Serverless will automatically upgrade as new versions are released, removing overhead of managing indexes as storage and traffic scales.

    Read the Performance Efficiency whitepaper 
  • With the services in this Guidance, you do not need to plan for capacity as the cost is per request, and the services will automatically scale out to meet demand. For example, OpenSearch Serverless will scale with your demand, so you don’t need to state how many indexes you require upfront. As these services are serverless, there is no infrastructure to manage, which significantly reduces the total cost of ownership.

    Read the Cost Optimization whitepaper 
  • Amazon S3 scales as data volumes increase, and you can set up S3 Lifecycle policies to automatically archive or delete data you no longer need. Amazon S3 provisions underlying resources as your storage grows and scales back when you delete objects, reducing overall resource consumption.

Implementation Resources

A detailed guide is provided to experiment and use within your AWS account. Each stage of building the Guidance, including deployment, usage, and cleanup, is examined to prepare it for deployment.

The sample code is a starting point. It is industry validated, prescriptive but not definitive, and a peek under the hood to help you begin.

The sample code; software libraries; command line tools; proofs of concept; templates; or other related technology (including any of the foregoing that are provided by our personnel) is provided to you as AWS Content under the AWS Customer Agreement, or the relevant written agreement between you and AWS (whichever applies). You should not use this AWS Content in your production accounts, or on production or other critical data. You are responsible for testing, securing, and optimizing the AWS Content, such as sample code, as appropriate for production grade use based on your specific quality control practices and standards. Deploying AWS Content may incur AWS charges for creating or using AWS chargeable resources, such as running Amazon EC2 instances or using Amazon S3 storage.

References to third-party services or organizations in this Guidance do not imply an endorsement, sponsorship, or affiliation between Amazon or AWS and the third party. Guidance from AWS is a technical starting point, and you can customize your integration with third-party services when you deploy the architecture.
