DevOps: automate your deliveries, your infrastructure and your monitoring
DevOps is a set of practices and tools that bring development and operations together to deliver more often, faster and with fewer incidents: continuous integration and deployment, infrastructure described as code, monitoring, incident management and automation of repetitive tasks.
This service is for technical teams that still deploy by hand, whose environments drift apart, who learn about outages from their customers, or who want to structure their delivery pipeline before growing. It applies to a start-up with one application as much as to an SME with several products.
We work across the whole chain: CI/CD pipelines with GitHub Actions or GitLab CI, infrastructure as code with Terraform, containerisation, GitOps deployments, observability with Prometheus and Grafana, secrets management. And we support the change in practices, because tooling alone is not enough.
When do we step in?
Manual, risky deployments
Going to production requires an SSH session, a sequence of commands and one specific person. Every release is stressful, and rollbacks happen in a rush.
Environments drifting apart
What works in development fails in staging or production because versions, variables and configuration differ. Infrastructure as code and containers remove that gap.
Outages discovered by users
No alert warns the team before complaints arrive. Metrics, centralised logs and meaningful alert thresholds are missing.
Infrastructure that cannot be reproduced
Servers were configured by hand over the years. Creating a test environment or replacing a machine takes days and nobody is sure of the result.
Growing team
Several developers ship in parallel and conflicts, regressions and blockages multiply. Automated tests, reviews and a clear release process are needed.
How we work
- 1
Delivery pipeline assessment
We map the path of a code change all the way to production: tools, manual steps, waiting time, incident frequency and rollback time. This assessment sets the priorities.
- 2
Bringing infrastructure under control
Describing existing and new environments in Terraform, with locked remote state, modules and change review through pull requests.
- 3
Containerisation and CI/CD pipelines
Reproducible Docker images, a pipeline that builds, tests, analyses and publishes every commit, then automated deployment to staging and production with approval where needed.
- 4
Safe, reversible deployments
Blue/green or canary strategies depending on the platform, database migrations compatible with rollback, and a one-command rollback procedure.
- 5
Observability
Metrics, logs and traces centralised with Prometheus, Grafana, Loki or a managed service, per-service dashboards, actionable alerts and a defined on-call process.
- 6
Team enablement
Documentation, training, a practice review after a few weeks, and adjustment of pipelines and alerts based on team feedback.

Why choose Agencei?
Pragmatism before tooling
We do not impose Kubernetes on a three-person team. We choose the level of automation your team can maintain, and we evolve it with you.
Development and operations expertise combined
We also write application code: our pipelines account for tests, schema migrations and the real constraints of your applications.
Security built into the chain
Secrets kept out of code, dependency and image scanning, minimal permissions for pipelines: security is part of the foundation, not a later step.
Knowledge transfer
Every setup is documented and explained. The goal is for your team to be autonomous, not dependent on us.
In brief
- What is this service?
- DevOps consulting that sets up continuous integration and deployment, infrastructure as code with Terraform, containerisation, GitOps and observability, along with the associated team practices.
- Who is it for?
- Technical teams at start-ups, SMEs and software publishers who deploy by hand, suffer from drifting environments or discover outages too late.
- What problem does it solve?
- Delivering more often and with more confidence, reducing production incidents, reproducing environments and making rollbacks fast.
- How long does it usually take?
- A first CI/CD pipeline usually takes a few days to a few weeks. A full transformation (IaC, containers, observability) often spans several months, in stages.
- What factors influence the price?
- The starting state of infrastructure and code, the number of applications and environments, the target platform, the expected level of observability and the extent of team training.
- How does the engagement run?
- Delivery pipeline assessment, infrastructure under Terraform control, containerisation and CI/CD pipelines, reversible deployments, observability, then team enablement.
- What are the risks?
- Tooling too complex for the team, slow or flaky pipelines, secrets exposed in repositories, too many ignored alerts, and drift between code and actual infrastructure.
- What alternatives exist?
- A PaaS platform that handles deployment and monitoring, a full-time in-house DevOps engineer, or traditional managed hosting without automation.
Frequently asked questions
Is DevOps just about tools?
No. Tools (CI/CD, Terraform, Docker) are the support, but what matters most is the change in practices: small frequent changes, automated tests, code review, shared responsibility for production. We support both aspects.
Where should we start if we have nothing?
Usually with a CI pipeline that builds and tests every commit, then automated deployment to a staging environment. Those are the quickest wins. Infrastructure as code and observability come next.
What is GitOps?
It is an approach where the desired state of infrastructure and deployments is described in a Git repository, and a tool such as Argo CD or Flux applies changes automatically. Git becomes the source of truth, with native history, review and rollback.
How long does it take to set up a DevOps chain?
A first working CI/CD pipeline can be set up in a few days to a few weeks. Bringing a whole infrastructure under Terraform, containerising and adding observability often spans several months, in stages that each deliver a concrete improvement.
Can you work on existing infrastructure without rebuilding everything?
Yes, that is the most common case. We import the existing setup into Terraform, gradually add pipelines and monitoring, and replace manual steps one by one without interrupting the business.
