Cloud & Hybrid Architecture
Most cloud architectures are designed for ideal environments: stable connectivity, continuous power, abundant IT teams. The reality on the ground is rarely like that. I design resilient hybrid and cloud infrastructures that keep running when MPLS links drop, when power cuts out, and when your data must respect local sovereignty regulations. The hybrid model is not a compromise — it is the responsible architecture for business continuity.
When it is relevant
Interconnecting 3 remote branch sites with automatic failover and cutting recurring costs from €86,500 to €41,700/year
Discuss this serviceExpected outcomes
Outage-resilient infrastructure: automated network link failover, redundant backups, and fully tested BCP/DRP.
Controlled, predictable costs: instance optimization and elimination of over-provisioning (e.g. recurring costs cut in half by year 2).
Seamless and secure interconnection of remote sites (headquarters & branches) without a single point of failure.
Complete skill transfer: documentation, runbooks, and local IT teams fully autonomous in daily operations.
Engagement scope
Infrastructure & network audit: mapping hardware, remote links, workloads, data sovereignty constraints, and operational costs.
Target architecture design: integrating automatic failover, hybrid storage strategy, and pragmatic sizing.
Infrastructure as Code deployment (Terraform): infrastructure automation, backup procedures, and Disaster Recovery Plans (DRP/BCP).
Migration & enablement: phased migration plan without critical downtime and operational training for IT teams.

- Full automation of network and server provisioning via Infrastructure as Code (Terraform)
FAQ
How long does an architecture engagement take?
A typical audit and architecture design engagement takes 2 to 4 weeks. The actual migration is executed in autonomous phases to avoid business downtime.
Do you only work with AWS and Azure?
I primarily work with AWS and Azure, but I adapt to your existing hosts (GCP, OVH, local datacenters) to build a cohesive hybrid solution.
How do you handle continuity during power or internet outages?
That's the core of the hybrid approach: local cache/relay storage, automatic failover to secondary links (4G/5G, SD-WAN), and deferred cloud sync upon reconnection.
What happens after the engagement?
I deliver full documentation (ADRs, runbooks), train your IT team to operate the new infrastructure independently, and remain available for ad-hoc support.
