Foundational models (FMs) are trained on large volumes of data and use billions of parameters. However, in order to answer customers’ questions related to domain-specific private data, they need to reference an authoritative knowledge base outside of the model’s training data sources. This is commonly achieved using a technique known as Retrieval Augmented Generation (RAG). By fetching data from the organization’s internal or proprietary sources, RAG extends the capabilities of FMs to specific domains, without needing to retrain the model. It is a cost-effective approach to improving model output so it remains relevant, accurate, and useful in various contexts. Knowledge Bases for Amazon Bedrock is a fully managed capability that helps you implement the entire RAG workflow from ingestion to…

Stop the CNAME chain struggle: Simplified management with Route 53 Resolver DNS Firewall
Starting today, you can configure your DNS Firewall to automatically trust all domains in a resolution chain (such as aCNAME, DNAME, or Alias chain). Let’s walk through this in nontechnical terms for those unfamiliar with DNS. Why use DNS Firewall? DNS Firewall provides protection for outbound DNS requests from your private network in the cloud (Amazon Virtual Private Cloud (Amazon VPC)). These requests route through Amazon Route 53 Resolver for domain name resolution. Firewall administrators can configure rules to filter and regulate the outbound DNS traffic. DNS Firewall helps to protect against multiple security risks. Let’s imagine a malicious actor managed to install and run some code on your Amazon Elastic Compute Cloud (Amazon EC2) instances or containers running inside…
Add your Ruby gems to AWS CodeArtifact
Ruby developers can now use AWS CodeArtifact to securely store and retrieve their gems. CodeArtifact integrates with standard developer tools like gem and bundler. Applications often use numerous packages to speed up development by providing reusable code for common tasks like network access, cryptography, or data manipulation. Developers also embed SDKs–such as the AWS SDKs–to access remote services. These packages may come from within your organization or from third parties like open source projects. Managing packages and dependencies is integral to software development. Languages like Java, C#, JavaScript, Swift, and Python have tools for downloading and resolving dependencies, and Ruby developers typically use gem and bundler. However, using third-party packages presents legal and security challenges. Organizations must ensure package licenses…
