What We Do On ECS

Four ways we work with Amazon ECS.

Most engagements start in one of these four lanes and expand over time. All of it is production work — task definitions, deployment controllers, scaling policies — not slideware. Broader platform needs are covered under our AWS DevOps services.

01 · BUILD

New ECS platforms, Fargate-first

Greenfield container platforms on ECS Fargate: multi-AZ services behind an ALB, auto-scaling on real signals (not CPU guesswork), blue-green or rolling deployments, ECR with lifecycle policies, and Terraform for the whole stack. We built exactly this for a hospitality SaaS backend — automated CI/CD, 99.95% uptime, and roughly 25% lower infrastructure cost than the setup it replaced.

ECS FargateALBECRTerraformAuto Scaling
02 · MIGRATE

Migrations into ECS

From Heroku, DigitalOcean Kubernetes, plain EC2, or another cloud. We containerise what needs containerising, move the data layer with a rehearsed cutover, rebuild CI/CD for container deploys, and run old and new in parallel until the numbers prove the switch. Nine applications off Heroku on this playbook, zero production outages. See Heroku to ECS, DigitalOcean to AWS, or the broader migration service.

03 · HARDEN

Compliance-grade hardening

ECS configured for auditors, not just for uptime: AWS WAF in front, GuardDuty and AWS Config watching everything, least-privilege task roles, secrets out of environment variables and into Secrets Manager, Multi-AZ redundancy, and CI/CD with approval gates. Our published ISO hardening engagement ran on the ECS EC2 launch type for a client with instance-level control requirements.

04 · OPERATE & OPTIMISE

Run it, and cut the bill

Ongoing ECS operations on a monthly retainer: right-sizing task definitions, scheduled scaling for dev environments, Fargate Spot where it is safe, Savings Plans where EC2 wins, ECR cleanup (one engagement removed 200+ stale images and enabled Auto Scaling for a financial compliance platform). Cost work runs under our AWS cost optimization practice — 20–35% reductions are typical on unoptimised accounts.

ECS vs EKS

The honest answer, not the fashionable one.

We deliver both ECS and EKS under our DevOps practice, so we have no incentive to steer you either way. Here is how we actually advise clients.

Choose ECS when…

You want containers without a platform team

  • No control plane to run. No cluster version upgrades, no node AMI patching cycles, no etcd to worry about.
  • Fargate removes hosts entirely. You define CPU and memory per task; AWS handles the rest.
  • Deep AWS integration by default. IAM task roles, ALB target groups, CloudWatch, Secrets Manager — wired in, not bolted on.
  • Smaller teams stay fast. A 5–30 engineer product team can own an ECS platform without hiring a Kubernetes specialist.
  • Cheaper to operate. No EKS control-plane fee, and far fewer engineering hours spent on platform care.
Choose EKS when…

You genuinely need Kubernetes

  • Existing K8s investment. Helm charts, operators, and manifests your team already maintains and trusts.
  • Portability is a hard requirement. Contractual or strategic multi-cloud commitments that ECS cannot satisfy.
  • Ecosystem dependencies. Workloads built around service meshes, custom controllers, or CNCF tooling with no ECS equivalent.
  • A platform team exists. You have (or will fund) engineers whose job is running the cluster itself.
  • Very large, heterogeneous estates. Hundreds of services where Kubernetes primitives earn their complexity.
Our pragmatic default: ECS Fargate for most scale-ups. Kubernetes is a fine tool and a poor status symbol — if a 30-minute review shows EKS is the right call for your workload, we will say so and build it. See our Amazon EKS consulting for how we run production Kubernetes on AWS.
Migration Paths

Proven routes into ECS.

Three paths we have run in production, each with a rehearsed cutover and a rollback point. All fall under our wider AWS migration service.

Heroku → ECS Fargate

Leave the Heroku bill behind

Dynos become Fargate tasks, Heroku Postgres becomes Aurora, git-push deploys become GitHub Actions with OIDC. Nine applications migrated on this exact playbook with zero production outages, and cost cuts of up to 60% versus equivalent Heroku spend.

4–8 weeks per application · 0 outages across 9 apps
Heroku to ECS migration
DigitalOcean K8s → ECS

Trade cluster upkeep for managed orchestration

We moved a containerised production application from DigitalOcean Kubernetes to Amazon ECS on the EC2 launch type — better scalability, lower operational overhead, and a cost-optimised footprint on AWS. The workloads were already containers; the win was removing the cluster-management burden.

K8s → ECS with reduced ops overhead & optimised cost

EC2 / VMs → ECS

Containerise the monolith, sensibly

Applications running on hand-managed EC2 instances or on-prem VMs get containerised incrementally: Dockerfiles and task definitions first, then a service at a time behind the same load balancer. No big-bang rewrite — the parallel run proves each move before traffic shifts.

Incremental service-by-service cutover, no big bang

Compliance On ECS

ECS that passes an audit, not just a health check.

AWS covers ECS under its own ISO 27001, SOC 1/2/3, and PCI DSS attestations — but the auditor is looking at your configuration layer: task roles, network paths, secrets handling, logging, and change control. That layer is what we harden.

We have delivered it in production — see the ISO hardening on ECS case study — and we hold ISO 27001:2022 ourselves, so we build to the standard we operate under. For teams heading into ISO 27001 or SOC 2 audits, the ECS work slots into the wider evidence trail your auditor expects.

Discuss your compliance posture →
  • Least-privilege task roles: one IAM role per service, no shared credentials, no wildcard policies.
  • Secrets out of env vars: Secrets Manager and SSM Parameter Store injected at task launch, rotated on schedule.
  • Edge and detection controls: AWS WAF in front of the ALB, GuardDuty and AWS Config rules watching drift and threats.
  • Network segmentation: private subnets for tasks, VPC endpoints for ECR and Secrets Manager, no public IPs on services.
  • Audited change control: CI/CD with approval gates, image scanning in the pipeline, and immutable ECR tags.
  • Multi-AZ by default: service placement across availability zones with health-checked, zero-downtime deploys.

Book a call →
ECS or EKS — which should we choose?+
For most scale-ups, ECS. It removes the Kubernetes control-plane tax: no cluster upgrades, no node patching debates, no dedicated platform engineer to keep it healthy. Choose EKS when you genuinely need Kubernetes — an existing Helm/operator investment, multi-cloud portability requirements, or workloads that depend on the K8s ecosystem. We deliver both, so our recommendation is based on your team and workload, not on what we prefer to sell. If a 30-minute review shows EKS is the right call, we will tell you that.
What does ECS Fargate actually cost to run?+
Fargate bills per vCPU-second and GB-second of memory your tasks actually request — no idle EC2 instances, no over-provisioned nodes. For spiky or moderate workloads it usually lands cheaper than self-managed nodes once you count engineering time; for large, steady workloads the EC2 launch type with Savings Plans can beat it. In our engagements, right-sized task definitions, scheduled scaling, and Fargate Spot for non-critical services have cut client bills by 20-35% on dev environments and up to 60% for teams leaving Heroku. Every proposal includes a line-item cost model before you commit.
How long does a migration to ECS take?+
Our Heroku-to-ECS migrations run 4-8 weeks per application, and we have migrated 9 applications on that playbook with zero production outages. A DigitalOcean Kubernetes to ECS move sits in a similar window. Timelines depend on the data layer (the database move is usually the critical path), the number of services, and how much of your CI/CD needs rebuilding. We give you a week-by-week plan with a parallel-run and rollback point before any traffic shifts.
Can ECS be ISO 27001 or SOC 2 compliant?+
Yes — we have done it in production. We delivered an ISO-hardened architecture on Amazon ECS with AWS WAF, GuardDuty, AWS Config rules, Multi-AZ redundancy, and audited CI/CD pipelines for a compliance-driven client. ECS itself is in scope for AWS’s own ISO 27001, SOC 1/2/3, and PCI DSS attestations; your responsibility is the configuration layer, which is exactly what we harden and document. HAZERCLOUD is itself ISO 27001:2022 certified, so we build to the standard we operate under.
Do you support the EC2 launch type, or Fargate only?+
Both. Fargate is our default for most services because it removes host management entirely. But two of our published ECS case studies run the EC2 launch type — one for an ISO-hardened workload that needed instance-level controls, one for a cost profile where Savings Plans on steady EC2 capacity beat Fargate pricing. We model both options in the architecture review and pick per-service, not per-dogma. Mixed clusters (Fargate for spiky services, EC2 for steady ones) are common in our deliveries.
What happens to our existing CI/CD pipelines?+
They get rebuilt to deploy containers, and usually end up simpler. If you are on GitHub Actions we add OIDC federation into AWS (no long-lived keys), build to ECR, and deploy with rolling or blue-green strategies via ECS deployment controllers or CodeDeploy. If you prefer AWS-native, we deliver CodePipeline + CodeBuild. Heroku-style git-push deploys are replaced with pipelines your team can actually inspect: automated tests, image scanning, environment promotion, and one-command rollback.
Can you take over an ECS environment someone else built?+
Yes — this is a common starting point. We begin with a 1-2 week assessment: task definition audit, scaling and health-check review, IAM and network posture, cost baseline, and a prioritised remediation list. One published engagement started exactly this way: we removed 200+ stale container images, enabled ECS Auto Scaling, and set ECR lifecycle policies for a financial compliance platform. After remediation, most clients move to a monthly retainer for ongoing operations.
