Private infrastructure practice
The power beneath
the cloud.
Overcast designs, builds and runs high-performance compute, Azure Local and advanced platforms for enterprises whose most important systems are rarely seen.
Most of our work is never seen. That is the point. We make the systems that matter most run faster, closer and under your control.
Discretion
We do not publish client names or architectures. What we build for you stays yours.
Precision
Every design is measured, benchmarked and tuned against the workload it has to carry.
Permanence
Platforms built to run for years, not to survive a demo.
Disciplines
Three disciplines. One standard.
High-performance compute
GPU and CPU clusters for AI training, simulation and analytics. Low-latency fabrics, parallel storage and schedulers, tuned until the numbers stop moving.
- GPU clusters
- RDMA fabrics
- Parallel storage
- Slurm
Azure Local
Azure services on hardware you control. Hyperconverged clusters in your data centre and at the edge, managed through Azure Arc and built for sovereignty.
- Hyperconverged
- Azure Arc
- Edge sites
- Sovereign
Advanced platforms
Landing zones, platform engineering, zero-trust identity and observability for estates that span public cloud, edge and on-premises.
- Landing zones
- Platform engineering
- Zero trust
- Observability
High-performance compute
Built for the workloads others avoid.
Training runs that cannot stall. Simulations that cannot wait for a queue. We design compute platforms around the physics of your workload, then stay until they perform.
- Accelerated clusters sized to the model, not the brochure
- RDMA networking and parallel file systems that keep GPUs fed
- Slurm, Kubernetes and Azure CycleCloud orchestration
- Benchmarks before, during and after go-live
Azure Local
Your cloud.
Your walls.
When data cannot leave the building, the cloud comes to it. We deploy and operate Azure Local so regulated and latency-sensitive workloads get the Azure control plane without giving up custody.
Control plane
Azure, through Azure Arc
Data
Stays inside your walls
Operations
Connected or disconnected
Approach
We start with a conversation, not a proposal.
- 01
Listen
A private conversation, under NDA if you prefer, about what you need to move, compute or protect.
- 02
Architect
A design built around your constraints, with nothing in it you do not need.
- 03
Build
Delivered by senior engineers end to end, measured against agreed benchmarks.
- 04
Operate
We stay on, quietly, for as long as the platform matters to you.
Contact
Briefings are by request.
Tell us, in a sentence, what you are trying to build. A senior engineer will reply personally.
