Serverless Migration

Move from expensive always-on compute to serverless architecture: reduce costs, eliminate patching, and scale automatically.

Overview

We migrate your existing services from EC2 or containerized architecture to a serverless model using Lambda, API Gateway, SQS, and EventBridge. The result is lower operational overhead, automatic scaling, and — in most cases — significantly lower costs.

Who this is for

• Teams running APIs on EC2 or ECS that have variable traffic patterns

• Companies with high AWS bills driven by compute costs

• Engineering teams that want to reduce operational overhead

Our approach

Assessment

We start by identifying which services are good candidates for serverless migration (event-driven, stateless, bursty) and which aren't (long-running processes, stateful workloads, latency-sensitive with high cold-start sensitivity).

Migration (service by service)

• API Gateway + Lambda for HTTP APIs

• SQS + Lambda for async workloads

• EventBridge + Lambda for event-driven patterns

• Step Functions for multi-step orchestration

Performance optimization

• Cold start minimization (package size, runtime selection, Lambda SnapStart)

• Provisioned Concurrency for latency-sensitive paths

• Lambda Power Tuning for cost/performance optimization

Operational readiness

• Lambda function monitoring and alerting

• Dead-letter queue configuration and alerting

• Distributed tracing with X-Ray

• Runbooks for common operational tasks

Outcomes

• 40–80% compute cost reduction (typical)

• Elimination of patching and AMI maintenance

• Automatic scaling without capacity planning

• Reduced operational overhead
