The Problem

Is Legacy Infrastructure Holding Back Your Development Velocity?

Organizations modernizing to the cloud often underestimate the complexity of serverless migration and architecture. Here are the four biggest challenges slowing your teams down and inflating your cloud bill.

Unpredictable Scaling & Cold Start Latency

Poorly architected serverless functions suffer from cold start penalties, inconsistent execution times, and runaway concurrency costs — turning a promising architecture into a performance and budget liability.

Fragmented Event-Driven Workflows

Disconnected Lambda functions, missing dead-letter queues, and uncoordinated event sources create silent failures, message loss, and debugging nightmares that take days to diagnose in production.

Serverless Security & Compliance Gaps

Overly permissive IAM roles, unencrypted environment variables, and missing API Gateway authorization layers expose serverless workloads to privilege escalation, data leaks, and compliance violations.

High Serverless Costs Without Observability

Without granular function-level cost tracking, memory rightsizing, and execution duration optimization, serverless workloads can generate cloud bills 3–5× higher than necessary — with no visibility into which functions are responsible.

✕ Without SISGAIN Serverless

✕ Manual server provisioning & patching

✕ Fixed compute costs regardless of traffic

✕ Cold start issues & unpredictable latency

✕ Monolithic deployments, long release cycles

✕ No function-level cost or performance visibility

✕ Overpermissive IAM & exposed endpoints

✕ Fragmented event workflows & silent failures

✓ With SISGAIN Serverless

✓ Zero infrastructure management — fully serverless

✓ Pay-per-execution billing — 60–80% cost reduction

✓ Provisioned concurrency & warm-up strategies tuned

✓ Micro-function pipelines with CI/CD automation

✓ Real-time observability with AWS X-Ray & Datadog

✓ Least-privilege IAM, API Gateway auth & WAF enforced

✓ Orchestrated step functions with DLQ & retry policies

Every Serverless Capability You Need

From function design to production deployment — we cover the complete serverless development lifecycle with enterprise-grade precision.

Serverless Architecture Design & Strategy

End-to-end serverless architecture blueprints — event topology mapping, function decomposition strategy, API Gateway design, data flow orchestration, and cloud-native integration patterns aligned to your business objectives and SLA requirements.

AWS Lambda Development & Optimization

Custom Lambda function development in Node.js, Python, Go, and Java — with memory and timeout rightsizing, provisioned concurrency configuration, Lambda layers for shared dependencies, and VPC integration for private resource access.

Azure Functions & Logic Apps Development

Full-lifecycle Azure Functions development with Durable Functions for stateful workflows, Logic Apps for low-code integrations, Event Grid routing, and Service Bus messaging — built on consumption or premium plan depending on latency requirements.

Google Cloud Run & Cloud Functions

Containerized serverless workloads on Cloud Run with autoscaling to zero, Cloud Functions for lightweight event triggers, Pub/Sub integration, and Eventarc for unified event routing across Google Cloud services.

Event-Driven Architecture & Workflow Orchestration

Design and implementation of event-driven systems using AWS EventBridge, SQS, SNS, Apache Kafka, and Azure Event Hubs — with AWS Step Functions or Azure Durable Entities for complex multi-step workflow orchestration and saga pattern implementation.

Serverless API Development & API Gateway

RESTful and GraphQL API development with AWS API Gateway, Azure API Management, or Google Cloud Endpoints — including request/response transformation, throttling policies, custom authorizers, usage plans, and WAF integration.

Serverless Security & Compliance Hardening

Least-privilege IAM policy design, secrets management via AWS Secrets Manager or Azure Key Vault, API Gateway JWT/OAuth2 authorization, function-level encryption, VPC endpoint policies, and compliance alignment with SOC 2, HIPAA, and GDPR requirements.

Serverless Migration & Modernization

End-to-end migration of monolithic applications, VM-based workloads, and containerized services to serverless — including strangler-fig decomposition, data layer refactoring, and zero-downtime cutover planning with automated rollback strategies.

How It Works

Serverless Intelligence — Live Demo

Explore how our serverless platform manages your function lifecycle across four core pillars in real time.

Multi-Cloud Function Provisioning

We provision and configure serverless functions across AWS Lambda, Azure Functions, and Google Cloud Run using Terraform and Serverless Framework — with standardized environment configurations, VPC integration, and IAM role boundaries as baseline.

Event Source Mapping & Trigger Design

Every function is wired to purpose-built event sources — SQS, SNS, EventBridge, API Gateway, S3, DynamoDB Streams — with filter patterns, batching configurations, and dead-letter queue routing enforced from day one.

Serverless Framework & IaC Standardization

Deployments are standardized using Serverless Framework, AWS SAM, or Terraform — with reusable function templates covering environment variables, layer dependencies, concurrency limits, and timeout policies across all services.

GitOps Sync & Continuous Deployment

GitHub Actions or GitLab CI pipelines continuously validate, test, and deploy function packages — automatically detecting configuration drift, enforcing code quality gates, and rolling back failed deployments without manual intervention.

IAM Least-Privilege Policy Enforcement

Every Lambda function receives a dedicated execution role scoped to the minimum permissions required. Permission boundaries prevent privilege escalation — blocking overpermissive role assumptions before functions reach staging or production environments.

API Gateway Authorization & WAF

Custom Lambda authorizers or Cognito-based JWT validation enforces API-level authentication. AWS WAF rules block SQL injection, XSS, and rate-limit abuse — protecting every serverless endpoint from common web exploits.

Secrets Management & Encryption

AWS Secrets Manager, Azure Key Vault, or GCP Secret Manager injects secrets at runtime — eliminating hardcoded credentials in function code. All environment variables are KMS-encrypted at rest and rotated on configurable schedules.

VPC Integration & Network Isolation

Sensitive functions run inside private VPCs with interface endpoints — preventing public internet exposure of data-layer resources. Security groups enforce zero-trust east-west communication between functions and downstream services.

Function Metrics & Dashboards

CloudWatch, Azure Monitor, or Google Cloud Monitoring collects invocation counts, error rates, duration percentiles, throttles, and cold start frequencies. Grafana dashboards provide real-time visibility per function, per event source, and per AWS account.

Distributed Tracing with X-Ray & OpenTelemetry

AWS X-Ray or OpenTelemetry captures end-to-end traces across serverless workflows — visualizing function chains, identifying cold start bottlenecks, and enabling sub-millisecond root-cause analysis across event-driven pipelines.

Structured Log Aggregation & Alerting

Fluent Bit or FireLens ships structured function logs to Loki, Elasticsearch, or your SIEM. Intelligent alerting fires on error rate spikes, timeout patterns, throttling breaches, and DLQ depth — with PagerDuty or Slack on-call routing.

SLO & Reliability Tracking

Service Level Objectives defined per API endpoint and function — automatically generating error budget dashboards, burn-rate alerts, and monthly SLO compliance reports for engineering and executive stakeholders.

Function-Level Cost Attribution

AWS Cost Explorer tags, Azure Cost Management, or Infracost provides real-time cost allocation by function, service, team, and environment — giving FinOps and engineering managers precise visibility into what each serverless workload costs per million invocations.

Memory Rightsizing & Duration Optimization

AWS Lambda Power Tuning analyzes execution duration versus memory allocation across 10 configurations — generating rightsizing proposals that minimize cost per GB-second while maintaining target latency SLAs for every function.

Provisioned Concurrency & Warm-Up Strategies

Provisioned concurrency is applied selectively to latency-sensitive functions — eliminating cold starts on critical paths while keeping idle capacity charges near zero for batch and async processing functions.

Serverless Efficiency Scoring

Monthly serverless efficiency reviews score function execution efficiency, memory utilization, timeout waste, and idle trigger costs — with a prioritized action plan to continuously reduce cloud spend as your workloads evolve.
