Agent Compute Deployment

Overview

Effective agent deployment requires selecting appropriate AWS managed compute services that balance security, cost efficiency, and operational simplicity. This document outlines our methodology for deploying agent workloads on AWS managed compute infrastructure, demonstrating expertise in service selection and optimization strategies.

Compute Service Selection Framework

Evaluation Criteria

Service selection considers multiple dimensions:

Workload Characteristics:

  • Request patterns (synchronous vs. asynchronous)
  • Latency requirements (real-time vs. batch)
  • Execution duration (seconds vs. minutes vs. hours)
  • Memory and CPU requirements
  • Concurrency expectations

Operational Requirements:

  • Scalability needs (auto-scaling, burst capacity)
  • Availability requirements (multi-AZ, regional)
  • Deployment frequency and complexity
  • Monitoring and observability needs
  • Cost optimization priorities

Security Posture:

  • Network isolation requirements
  • IAM integration complexity
  • Secrets management approach
  • Compliance and audit requirements

AWS Managed Compute Options

Amazon Bedrock AgentCore Runtime

Recommended for: Production agentic AI workloads requiring managed infrastructure

Amazon Bedrock AgentCore Runtime provides a fully managed execution environment for agents:

Capabilities:

  • Secure serverless agent hosting
  • Automatic scaling based on demand
  • Built-in session management
  • Native Bedrock model integration
  • AgentCore Gateway for tool orchestration
  • AgentCore Memory for conversation persistence

Architecture Pattern:

Client Request → API Gateway → AgentCore Runtime →
├─ Agent Execution (Strands/Bedrock Agents)
├─ Tool Invocation via AgentCore Gateway
├─ Memory Access via AgentCore Memory
└─ Model Inference via Amazon Bedrock
→ Response Streaming → Client

Security Features:

  • VPC integration for network isolation
  • IAM-based authentication
  • Encryption at rest and in transit
  • CloudTrail audit logging

Cost Model:

  • Pay-per-invocation pricing
  • No idle capacity charges
  • Included scaling and management

AWS Lambda

Recommended for: Event-driven agent tools, lightweight orchestration, API backends

Lambda provides serverless compute for agent components:

Use Cases:

  • Agent tool implementations
  • API backend handlers
  • Event processing (S3, DynamoDB streams)
  • Scheduled agent tasks

Configuration Recommendations:

  • Memory allocation based on workload profiling
  • Timeout settings aligned with SLAs
  • Provisioned concurrency for latency-sensitive paths
  • Layer usage for shared dependencies

Architecture Pattern:

Event Source → Lambda Function →
├─ Business Logic Execution
├─ AWS Service Integration
└─ External API Calls
→ Response/Next Action

Optimization Strategies:

  • Right-size memory allocation (128MB - 10GB)
  • Connection pooling for database access
  • Async invocation for non-blocking operations
  • Reserved concurrency for critical functions

Amazon ECS with Fargate

Recommended for: Long-running agent processes, container-based deployments

ECS Fargate provides serverless container orchestration:

Use Cases:

  • Persistent agent services
  • Batch processing workloads
  • Custom runtime requirements
  • Complex dependency management

Architecture Pattern:

Load Balancer → ECS Service (Fargate) →
├─ Container Task Execution
├─ Service Discovery Integration
└─ Auto-scaling based on metrics
→ Response

Configuration Recommendations:

  • Task CPU and memory sizing based on profiling
  • Service auto-scaling policies (target tracking, step scaling)
  • Health check configuration for reliability
  • Log driver configuration for CloudWatch integration

Security Configuration:

  • Task execution role with minimal permissions
  • Task role for application permissions
  • Security groups for network access control
  • Secrets injection from Secrets Manager

Amazon EKS

Recommended for: Complex multi-agent systems, Kubernetes-native organizations

EKS provides managed Kubernetes for sophisticated deployments:

Use Cases:

  • Multi-agent orchestration platforms
  • Hybrid cloud deployments
  • Teams with Kubernetes expertise
  • Complex networking requirements

Architecture Pattern:

Ingress Controller → Kubernetes Service →
├─ Pod Deployment (agent containers)
├─ Horizontal Pod Autoscaler
├─ Service Mesh (optional)
└─ Persistent Volume Claims
→ Response

Operational Considerations:

  • Node group sizing and instance selection
  • Cluster autoscaler configuration
  • Add-on management (CoreDNS, kube-proxy, VPC CNI)
  • Monitoring via Container Insights

Deployment Strategies

Blue/Green Deployment

Zero-downtime deployments with instant rollback:

Production (Blue) ← Traffic
├─ Deploy to Green environment
├─ Validate Green health
├─ Switch traffic Blue → Green
└─ Retain Blue for rollback
New Production (Green) ← Traffic

Implementation:

  • CodeDeploy for Lambda and ECS
  • Route 53 weighted routing for gradual shift
  • ALB target group switching for instant cutover

Canary Deployment

Gradual traffic shift with monitoring:

Production ← 95% Traffic
Canary ← 5% Traffic
├─ Monitor error rates, latency
├─ Gradually increase canary percentage
└─ Full promotion or rollback

Implementation:

  • Lambda aliases with weighted routing
  • ECS service with multiple task definitions
  • CloudWatch alarms for automatic rollback

Rolling Deployment

Incremental update of running instances:

[v1] [v1] [v1] [v1] ← Initial state
[v2] [v1] [v1] [v1] ← First batch
[v2] [v2] [v1] [v1] ← Second batch
[v2] [v2] [v2] [v2] ← Complete

Implementation:

  • ECS rolling update configuration
  • EKS rolling deployment strategy
  • Health check validation between batches

Cost Optimization

Right-Sizing

Continuous optimization of resource allocation:

  • Lambda memory profiling with AWS Lambda Power Tuning
  • ECS task size analysis with Container Insights
  • Compute Optimizer recommendations review

Reserved Capacity

Cost reduction for predictable workloads:

  • Savings Plans for Lambda and Fargate
  • Reserved Instances for EKS node groups
  • Commitment analysis based on historical usage

Spot Integration

Cost optimization for fault-tolerant workloads:

  • ECS Fargate Spot for batch processing
  • EKS Spot node groups for non-critical workloads
  • Graceful handling of Spot interruptions

Security Posture

Network Security

  • VPC deployment with private subnets
  • VPC endpoints for AWS service access
  • Security groups with minimal ingress rules
  • Network ACLs for subnet-level control

Identity and Access

  • Execution roles with least privilege
  • Task/pod identity for application permissions
  • Secrets injection (never environment variables)
  • Credential rotation automation

Encryption

  • In-transit encryption (TLS 1.2+)
  • At-rest encryption for all storage
  • KMS key management with rotation
  • Client-side encryption where appropriate

Monitoring and Observability

Metrics Collection

  • CloudWatch Container Insights for ECS/EKS
  • Lambda Insights for function telemetry
  • Custom metrics for business KPIs
  • X-Ray tracing for distributed operations

Alerting Configuration

  • Latency percentiles (p50, p95, p99)
  • Error rates and types
  • Resource utilization trends
  • Cost tracking and forecasting
