With AWS Bedrock, users can experiment with various FMs, customize them with their data, and create managed agents for complex business tasks, all without writing a single line of code.

Why should I Use Bedrock?

Amazon Bedrock offers a unique set of features and benefits that make it a compelling choice for those looking to harness the power of generative AI. Here’s why you should consider using Amazon Bedrock:

  • Diverse Foundation Model Selection: Bedrock provides a streamlined developer interface to engage with a vast array of top-tier Foundation Models (FMs) from not only Amazon but also renowned AI entities such as AI21 Labs, Anthropic, Cohere, Meta, and Stability AI. This allows for swift experimentation in the playground and the convenience of a unified API for inference. This design ensures adaptability with models from various sources and facilitates seamless updates to the latest model iterations with minimal code adjustments.
  • Effortless Model Personalization: Bedrock empowers you to tailor FMs with your proprietary data through an intuitive visual platform, eliminating the need for coding. Simply designate the training and validation datasets located in Amazon S3, and if necessary, tweak the hyperparameters to optimize model efficacy.
  • Autonomous Agents with Dynamic API Invocation: Construct agents capable of managing intricate business operations, ranging from travel arrangements and insurance claim processing to ad campaign creation, tax preparation, and inventory management. These agents, backed by Bedrock, enhance the analytical prowess of FMs by segmenting tasks, formulating an orchestration strategy, and implementing it.
  • Inherent Retrieval Augmentation with RAG: Bedrock’s Knowledge Bases allow for a secure integration of FMs with your data repositories, offering retrieval augmentation directly within the managed service. This not only amplifies the inherent capabilities of the FMs but also enriches them with domain-specific knowledge pertinent to your organization.
  • Upholding Data Integrity and Regulatory Compliance: Bedrock prioritizes data security and has secured certifications for HIPAA eligibility and GDPR adherence. With Bedrock, the enhancement of base models doesn’t utilize your content, and no data is relayed to third-party model vendors. All data within Bedrock is encrypted both in transit and when stored, with an added option to use custom encryption keys. For enhanced security, AWS PrivateLink can be used with Bedrock to ensure private connectivity between your FMs and your Amazon VPC, keeping your data traffic away from public internet exposure.
  • Scalability and Flexibility: As businesses grow and evolve, so do their data needs. Bedrock is designed to scale with your requirements, ensuring that as your data volume or complexity increases, the platform can handle it without compromising performance.
  • Integrated Ecosystem: Bedrock seamlessly integrates with other AWS services, ensuring that you can build comprehensive solutions that leverage the broader AWS ecosystem. This integration ensures that data flow, processing, and storage are cohesive and efficient across the board.
  • Availability: As of October 10, 2023, AWS Bedrock has expanded its reach and is now available in three global regions: US East (N. Virginia), US West (Oregon), and Asia Pacific (Tokyo).
