Cloud Labs provides a unique opportunity to work directly with AWS services including Amazon Bedrock and other AI/ML services to solve practical challenges and implement real-world solutions.
Your first app is simple—users set preferences, and you manually fine-tune their experience. It works, but it’s tedious. As your audience grows, the cracks start showing:
Personalization struggles: Users expect tailored experiences, but manual adjustments can’t scale.
Slow iteration: Updating the app based on feedback takes hours, sometimes days.
Scaling pains: More users, data, and work—yet the app remains static.
This is where AI changes the game. Instead of reactive, manual updates, AI dynamically adapts to users in real time, making apps more intelligent, efficient, and scalable.
But AI integration is often complex—until now. Amazon Bedrock makes it easy to build AI-powered applications without managing infrastructure or training models from scratch.
In this blog, we’ll explore how to harness Amazon Bedrock to create intelligent applications that are fast, scalable, and tailored to user needs.
The benefits of AI integration are undeniable, but building AI-powered solutions remains a complex challenge. Selecting the right models, managing infrastructure, and ensuring scalability requires significant effort during development and deployment.
That’s where Amazon Bedrock comes in. As a fully managed AWS service, Bedrock simplifies AI application development by providing access to pretrained generative AI models from top providers. Developers can leverage these models for tasks like text generation, image creation, and more—without needing to manage infrastructure or train models from scratch.
Key features of Amazon Bedrock are:
Pretrained models with customization: Use cutting-edge AI models and fine-tune them for specific use cases.
Single API for seamless integration: Interact with multiple models through a unified API, reducing development overhead.
These capabilities minimize complexity, allowing businesses to integrate AI quickly while ensuring solutions align with unique requirements. Pretrained models reduce development time, while customization provides flexibility to meet specific business needs.
Now that we’ve explored Amazon Bedrock and its core features let’s dive into the generic steps to integrate Bedrock into your application. These steps provide a high-level roadmap for using Bedrock to build AI-powered applications.
The first step is to identify the foundation model that is most suitable for your application. Foundation models are pretrained models that perform various AI tasks, such as natural language processing and image generation.
For selecting a model, clarify the following aspects of your use case:
Task type:
Is it text generation, summarization, classification, question-answering, or another task?
Do you need multilingual support or specific domain expertise (e.g., legal, healthcare)?
Performance criteria:
How important are accuracy, latency, and scalability for your application?
Are you working with constraints like low latency for real-time applications?
Integration needs:
Once you have the answers to these questions. Select the foundation model that best suits your requirements. Bedrock provides access to models from different providers, some of which are listed below:

If Bedrock’s models do not fully meet your requirements, you also have the option to build custom models tailored to your specific use case. While this requires additional effort, it enables you to leverage your proprietary data and domain expertise to deliver optimal performance for your unique needs.
Once you’ve chosen a foundation model that is not a custom model designed specifically to meet your needs, the next step is to fine-tune it. Fine-tuning a model involves training it on a smaller, domain-specific dataset to better align it with your application’s objectives.
Fine-tuning works by adjusting the model’s parameters, improving its performance in the context of your application. Here are the steps involved in fine-tuning a foundation model:
Dataset preparation: To begin, gather and prepare a domain-specific dataset. This could include historical customer interactions, product data, brand messaging, or relevant content.
Training the model: You then train the model on this dataset, adjusting its weights and biases to better understand and replicate patterns specific to your application. This fine-tuning process involves feeding the model examples from the dataset so that it can adapt its responses. Here are a couple of examples of improvements across different domains achieved through fine-tuning:
Customer support: Fine-tuning a language model with historical chat logs enables the model to learn common customer inquiries, company-specific terminology, and the typical style of responses. As a result, the model can more effectively address customer support questions and provide personalized answers.
Marketing content: Training the model with brand-specific materials, such as email campaigns, website copy, and social media posts, helps the model generate content that reflects the tone, style, and language your brand uses. For instance, if your brand communicates with a casual, friendly tone, fine-tuning ensures the model produces engaging social media posts or email copy in that same style.
Customization also includes adjusting parameters like:
Temperature: Controls the randomness of responses.
Example: A higher temperature (e.g., 0.8) might generate creative and varied outputs, making it suitable for brainstorming marketing ideas: “Discover new horizons with our eco-friendly products that make your life vibrant and colorful!”
A lower temperature (e.g., 0.2) produces more focused and deterministic outputs, ideal for tasks requiring accuracy, like answering factual questions like, ‘Our product is made from 100% recycled materials.’
Max tokens: Limits the length of generated responses.
Example: A shorter token limit (e.g., 50 tokens) ensures concise outputs, useful for applications like chatbots: “Yes, your package will arrive tomorrow.”
A longer token limit (e.g., 200 tokens) allows for more detailed responses, helpful for generating comprehensive summaries: “Your package is scheduled for delivery tomorrow. You can track its progress on our website using the tracking ID provided in your order confirmation email.”
By adjusting these parameters, you can tailor the model’s behavior to better suit specific use cases, whether you need creative, detailed responses or precise, concise ones.
A knowledge base can enhance the model for applications requiring domain-specific expertise. In Amazon Bedrock, a knowledge base refers to structured data, such as a company’s product catalog, FAQs, troubleshooting guides, or industry-specific documentation, that can enhance the model’s responses.
When integrated, the knowledge base is an additional resource the AI model references, providing more accurate and relevant responses by leveraging up-to-date, domain-specific information rather than relying solely on pretrained data.
Prepare the knowledge base:
Structure your data into a machine-readable format (e.g., JSON, XML, or CSV).
Include relevant fields such as product names, descriptions, specifications, FAQs, and troubleshooting steps.
A JSON file for an e-commerce knowledge base might look like this:
{"products": [{"name": "Wireless Earbuds","description": "High-quality sound with noise cancellation.","price": "$99","faq": ["How long does the battery last?","Does it support Bluetooth 5.0?"]}]}
Upload to Bedrock:
Use Bedrock’s interface or APIs to upload and configure the knowledge base. Ensure the data is accessible and updated regularly.
Enable knowledge integration:
Configure your AI model to reference the knowledge base during runtime. This may involve specifying the knowledge base as part of the query or using additional parameters.
E-commerce: Enhance product recommendation systems by providing accurate details about inventory, promotions, or specifications.
Health care: Equip the AI with medical guidelines and research papers to suggest treatment options or offer contextually relevant advice.
Education: Provide AI-driven responses to student queries by referencing course materials and syllabi.
Input: The user asks a question (e.g., What are the features of the wireless earbuds?).
AI model: References the knowledge base for the latest product data.
Output: The wireless earbuds offer high-quality sound, noise cancellation, and Bluetooth 5.0 support.
If your application needs to perform specific tasks based on user inputs, action groups in Amazon Bedrock can streamline the process. An action group is a collection of predefined tasks that the AI model triggers in response to user inputs.
Action groups extend the model’s capabilities beyond generating content. They enable it to interact with external systems, perform calculations, or trigger workflows such as sending notifications or calling APIs.
Define actions: List the tasks your application needs to perform, such as:
Sending an email
Updating a database
Triggering a Lambda function
Configure action triggers: Use Bedrock’s interface or APIs to define triggers for each action. These triggers can be based on keywords, intents, or user input patterns.
Implement action handlers: Write the logic to handle actions, ensuring seamless integration with your application’s backend.
A simple Python handler for sending an email might look like as follows:
def send_email(recipient, subject, body):# Logic to send an email using AWS SES or other serviceprint(f"Email sent to {recipient} with subject: {subject}")
Test and optimize:
Verify that the actions execute correctly under various scenarios. Optimize the triggers and handlers for performance.
Customer support: A chatbot identifies a user’s issue and triggers a workflow to create a support ticket in an external system.
Retail: A recommendation system triggers notifications when users interact with a specific product category.
Finance: The AI detects anomalies in a transaction and triggers a fraud alert.
Input: The user states, “I want to subscribe to the newsletters.”
Trigger: AI identifies the intent and activates the subscribe_newsletters action.
Action: The backend workflow sends a subscription confirmation email and updates the database.
With the model selected and customized, the final step is to integrate it into your application. Using Bedrock’s unified API, you can easily send inputs to the model and process its responses. A simple way to achieve this is by creating a dedicated function within your application that takes a user’s input (prompt) and interacts with the model to return a response.
Here’s how this can fit into your application architecture:
Create a reusable function that seamlessly sends user inputs to the Bedrock API and retrieves AI-generated responses. This function bridges your application and the AI model, allowing your app to interact with Bedrock. You can easily integrate this functionality into your application by leveraging AWS SDKs. These SDKs offer convenient methods for calling the Bedrock model, handling requests, and processing responses efficiently. Depending on your application’s framework, select the appropriate SDK and design the function to meet your needs. A sample function might look like this:
require 'aws-sdk-bedrock'require 'json'def invoke_bedrock_model(model_id, input_text)"""Invokes an Amazon Bedrock model using the AWS SDK for Ruby.:param model_id: The ARN of the foundation model to invoke.:param input_text: A hash representing the input payload for the model.:return: The response from the model."""client = Aws::Bedrock::Client.new(region: 'us-east-1')beginresponse = client.invoke_model({model_id: model_id,content_type: "application/json",body: input_text.to_json})return JSON.parse(response.body.string)rescue Aws::Bedrock::Errors::ServiceError => eputs "Error invoking model: #{e.message}"return nilendend
Call this function wherever AI-driven tasks are needed, such as generating responses in a chatbot, suggesting recommendations, or automating text-based tasks.
Wrap the function within a backend service or serverless architecture, such as AWS Lambda, to handle scaling and performance requirements for real-time usage.
