Is the AWS Bedrock Academy free?

Yes. The full course is free and includes 25 modules, 52 lessons, 52 labs, and quiz-based progression with no sign-up required.

How is Infinity AWS Bedrock Academy different from AWS Skill Builder?

Unlike AWS Skill Builder which often gates advanced hands-on labs behind paid subscriptions or AWS Builder ID logins, Infinity Tech Stack's AWS Bedrock Academy is 100% free, ungated, and browser-first with zero sign-up required. It includes 25 modules, 52 lessons, 52 hands-on labs, and 125+ quiz checks covering the Converse API, Bedrock Guardrails, AgentCore, and multi-model evaluations without requiring active AWS account credentials.

What is Amazon Bedrock and how does its architecture operate?

Amazon Bedrock is AWS's fully managed foundation model service providing serverless inference across top providers (Anthropic, Meta, Mistral, Amazon Nova/Titan) via a unified Converse API, backed by AWS IAM, KMS encryption, and VPC PrivateLink isolation.

What is the Amazon Bedrock Converse API and why should you use it over InvokeModel?

The Converse API provides a unified request and response specification across all foundation models on Bedrock. It standardizes system prompts, structured tool use, and multi-turn message history, eliminating vendor-specific payload differences.

How does Amazon Bedrock AgentCore differ from Classic Bedrock Agents?

Classic Bedrock Agents entered maintenance mode (closed to new customers on July 30, 2026), succeeded by Amazon Bedrock AgentCore. AgentCore is AWS's modern, modular agent platform featuring serverless runtimes with sub-second cold starts, zero-boilerplate MCP Gateway tool integration, cross-session episodic memory, and the AgentCore Consent Portal.

How do Bedrock Guardrails enforce safety and PII redaction?

Bedrock Guardrails apply customizable safety policies across both user inputs and model outputs. They block toxic content, enforce Automated Reasoning hallucination checks, and anonymize sensitive PII (emails, SSNs, credit cards) using AWS-managed entity detectors.

What retrieval strategies are supported in Bedrock Knowledge Bases?

Bedrock Knowledge Bases support dense vector retrieval using Titan or Cohere embeddings, BM25 keyword lexical search, native HYBRID search combining vector and sparse rankings, and cross-encoder neural reranking.

How does Bedrock Cross-Region Inference prevent 429 throttling exceptions?

Cross-region inference profiles automatically distribute traffic across multiple regional AWS data centers (e.g., us-east-1, us-west-2, us-east-2), pooling quotas dynamically to absorb traffic spikes without requiring custom client retry code.

What are Amazon Nova models on Bedrock?

Amazon Nova is AWS's flagship model family, including Nova Micro (ultra-fast text), Nova Lite (cost-effective multimodal), Nova Pro (balanced intelligence), and Nova Premier (frontier reasoning), engineered for high-throughput enterprise workloads.

How does prompt caching operate on Amazon Bedrock?

Prompt caching stores frequent prefix tokens in memory for subsequent requests. Cache hits reduce input token billing by up to 90% and lower invocation latency by over 80% on large system prompts, codebases, and legal documents.

What is Provisioned Throughput (PT) and when should it be purchased?

Provisioned Throughput allocates dedicated model units to guarantee steady-state inference performance and strict SLA compliance for mission-critical production applications with predictable traffic volumes.

How does Bedrock model evaluation work for custom and foundation models?

Bedrock Model Evaluation supports automated algorithmic scoring across metrics like accuracy, robustness, and toxicity, as well as human-in-the-loop review teams via Amazon SageMaker Ground Truth integration.

How are Bedrock API calls secured with AWS KMS and PrivateLink?

Customer Managed Keys (CMKs) provide customer-controlled envelope encryption for model weights and Knowledge Base vector stores. AWS PrivateLink VPC endpoints keep inference traffic strictly within the customer's private virtual cloud.

How does Bedrock integrate with AWS Lambda and Amazon API Gateway?

Bedrock agents invoke AWS Lambda functions to execute enterprise actions, while Amazon API Gateway provides secure HTTP/REST endpoints with Cognito JWT authentication, usage tiers, and DDoS protection.

What telemetry and observability tools are available for Bedrock?

Amazon Bedrock streams runtime metrics (latency, token consumption, error codes) directly to Amazon CloudWatch, writes complete invocation audit records to CloudWatch Logs or S3, and integrates with AWS X-Ray for distributed agent tracing.

How can organizations implement chargeback and cost allocation for Bedrock?

Organizations apply AWS Cost Allocation Tags (e.g. CostCenter, Team, Environment) to inference profiles and application roles, analyzing usage via AWS Cost Explorer and establishing budget guardrails with AWS Budgets.

What chaos testing and disaster recovery patterns apply to Bedrock?

Resilience patterns include Route 53 Application Recovery Controller (ARC) regional failover, AWS Fault Injection Simulator (FIS) synthetic throttling injection, and circuit breakers with fallback response caches.

Can I earn an official certificate upon completing AWS Bedrock Academy?

Yes! Completing all 25 modules unlocks the official Infinity AWS Bedrock AI Architecture Mastery Certificate with your cryptographic verification ID and one-click LinkedIn badge sharing.

Regional Failover Patterns

📚 Multi-Region Resilience⏱ 10 min⭐ 115 XP⌨ Hands-on lab

Failover Is a Product Requirement

Use active-passive or active-active strategies depending on your latency and compliance profile. Bedrock adds one twist classic DR plans miss: the same model may not exist - or behave identically - in your failover region, so model equivalence is part of your failover design.

Strategy Options

Strategy	Shape	Cost/complexity	Fit
Cross-region inference profiles	AWS routes across a geography automatically (us./eu. prefixed IDs)	Lowest - built in	First line of defence for throughput + regional blips
Active-passive	Standby region with config + quotas pre-provisioned; DNS/flag flip to fail over	Medium	Most teams; clear runbook, bounded spend
Active-active	Both regions serve traffic continuously	Highest - double quotas, sync complexity	Hard availability targets, global user base

The Model Equivalence Map

# failover-map.yaml
primary:   us-east-1
secondary: us-west-2
models:
  amazon.nova-pro-v1:0:      same-id          # verified available
  anthropic.claude-sonnet-*: us.profile       # cross-region profile covers both
  custom.triage-ft-v2:       nova-pro + prompt-v3-fallback   # custom models don't failover - plan the substitute!

Custom models and Provisioned Throughput are region-bound - your failover plan must name the substitute and accept its eval-scored quality delta in advance.

What Must Be True Before You Can Fail Over

Model access granted in the secondary region (it is account+region scoped - module 2).
Quotas raised in the secondary - default TPM in an unused region will not absorb your production load.
Guardrails, prompts, KB replicas deployed - inference without your safety config is not a failover, it's an incident.
Data residency audited - an EU workload failing over to us-east-1 may trade an outage for a compliance breach.
Runbooks tested and current - untested failover plans fail at the worst possible moment (next lesson: chaos drills).

Quota trap: teams provision failover infra but forget service quotas. The failover "works" - at 5% of required throughput. Request secondary-region quota increases as part of DR setup, not during the incident.
