The problem you're facing
An improvised Kubernetes migration gives containers that copy VM flaws: everything in one image, hidden configuration, no healthchecks. You "containerised" without changing operations : and the cluster adds complexity without bringing benefits.
Our answer
We migrate with architecture in mind: application decomposition, externalised configuration, healthchecks, declarative deployments and CI/CD pipelines. Migration is the opportunity to modernise operations, not just to wrap the existing in Docker.
What LaMeDuSe takes care of
- Applicability audit: which applications, in which order
- Containerisation with best practices (light images, externalised config)
- Reviewed and documented Kubernetes / Helm manifests
- CI/CD pipeline for cluster deployment
- Data strategy: StatefulSets, storage, databases
- Progressive migration with VM / container cohabitation
- Training your teams in Kubernetes operations
Our methodology
- 1
Inventory & mapping
Applications, data, dependencies and flows: you only migrate well what you have mapped.
- 2
Migration plan
Migration order, intervention windows, rollback plan and success criteria defined per application.
- 3
Rehearsal
Every migration is rehearsed in a test environment before the real switch: no first time in production.
- 4
Cutover & stabilisation
Execution on D-day, verification of monitoring, backups and performance, then handover.
Relevant technologies
Security
Encrypted transfers, segmentation of source and target environments, and data integrity checks after every step.
Hosting & infrastructure
The target can be our European cloud or your own infrastructure: we migrate to what serves your constraints, not the other way round.
Maintenance
After the cutover, operations can stay with us (managed services) or return to your teams, with full documentation.
Why LaMeDuSe
Our own platforms run on Kubernetes, administered by our teams in Europe. We don't migrate to Kubernetes "because it's fashionable": we operate production clusters daily, and we know what this migration brings : and what it doesn't.
Frequently asked questions
No: stateless applications with variable load gain clearly; an isolated database or a small stable service, often less. We decide application by application : sometimes the right answer is a well-administered VM.
A first application migrated with a complete pipeline: a few weeks. Generalisation across an application portfolio: staged over months, starting with the applications that gain the most.
Depending on the case: StatefulSet with persistent storage on the cluster, or a dedicated service off-cluster (often simpler to operate). We recommend based on criticality, volume and your teams : not dogma.
Not necessarily: we offer the managed cluster (we administer, you deploy). If you want to internalise, training and handover are part of the service : but it's not an obligation.
