Problem

Create a repeatable EKS blueprint that reduces manual work and provides a controlled application delivery foundation.

Sample content for layout validation. Replace it with verified implementation evidence before presenting this as a completed case study.

Constraints

  • The current architecture is a draft
  • Secrets must never be committed
  • The environment must be disposable and reproducible

Success criteria

  • Terraform plans are reviewable
  • Workloads reconcile from Git
  • Monitoring evidence exists before completion

Architecture

The architecture separates clear responsibilities so each component can be tested, operated, and changed independently.

Terraform

Models the VPC, EKS cluster, and supporting AWS resources as code.

Argo CD

Reconciles the desired workload state from Git into the cluster.

Prometheus + Grafana

Collects operational metrics and presents platform dashboards.

Implementation

The work is organized into phases with explicit tools and verifiable outputs.

  1. Design

    Define platform boundaries

    Separate networking, cluster, delivery, and telemetry responsibilities.

    Tools: AWS · EKS · Output: Architecture draft
  2. Provision

    Model infrastructure

    Prepare reusable modules and a state strategy for AWS resources.

    Tools: Terraform · Output: Terraform module plan
  3. Build

    Establish GitOps

    Define repository structure and workload reconciliation flows.

    Tools: Argo CD · GitHub Actions · Output: GitOps workflow draft
  4. Secure

    Design platform controls

    Plan least-privilege access, secret handling, and network boundaries.

    Tools: IAM · KMS · Output: Security checklist
  5. Observe

    Define telemetry

    Identify the metrics, dashboards, and alerts required for validation.

    Tools: Prometheus · Grafana · Output: Observability plan
  6. Optimize

    Review operations

    Build an optimization backlog after real measurements are available.

    Tools: AWS Cost Explorer · Output: Optimization backlog

Security

These items describe concrete controls or work that still requires verification.

  • IAM roles are designed around least privilege.
  • Secrets are referenced from a secret manager rather than committed to Git.

Observability

  • Metrics and alert thresholds remain pending until a real environment is available.

Results

  • The platform blueprint and acceptance criteria are in progress.
  • No uptime, cost, or performance claims are published without evidence.

Challenges and lessons learned

Challenge

EKS flexibility can introduce significant operational complexity.

Approach

Validate networking, cluster, delivery, and telemetry as separate layers.

Lesson

Mark the project complete only after collecting evidence from a running environment.
