Enterprise Cloud-Native Architecture

Core services ✓Projects

What is this?

Cloud-native architecture uses containers, microservices, declarative APIs, and continuous delivery built for elastic cloud platforms.

Why should you care?

AwsVerse modernizes legacy ERP adapters while new SaaS features ship cloud-native on EKS and serverless.

See it live — copy this example

Run in AWS CloudShell / local AWS CLI v2, or follow the matching steps in the AWS Console (Free Tier).

apiVersion: apps/v1
kind: Deployment
metadata:
  name: awsverse-catalog
spec:
  replicas: 3
  selector:
    matchLabels:
      app: catalog
  template:
    metadata:
      labels:
        app: catalog
    spec:
      containers:
        - name: catalog
          image: 123.dkr.ecr.ap-south-1.amazonaws.com/catalog:1.4.2
          ports:
            - containerPort: 8080

What happened?

  • Kubernetes Deployment manifest runs three catalog pods from ECR image.
  • GitOps controller applies YAML on merge to main.

Practice next

  1. Containerize one service; push to ECR.
  2. Deploy to EKS with Deployment and Service.
  3. Add HPA on CPU for autoscale.
  4. Add liveness and readiness probes.
  5. Introduce External Secrets Operator for Secrets Manager.

Remember

Containers plus CI/CD plus observability. Declarative infra and apps. Design for failure and scale.

AwsVerse cloud-native pivot

Board mandates 80% new code cloud-native.

Outcome: EKS plus serverless pattern library accelerates squad onboarding.
