Cloud Architecture & Migration
A cloud platform that survives its first bad day.
Cloud platforms rarely fail because of a bad instance type. They fail because nobody drew the boundaries — between accounts, networks, environments and teams — before the workloads arrived.
We design those boundaries first, then migrate into them.
The problem
Most cloud estates grow by accident. A workload lands somewhere, then another, and eventually nobody can say which account owns what, why the bill moves, or what happens when an availability zone disappears. Migrations stall because the target was never designed — only assumed.
What we deliver
- Multi-account landing zone design with clear account, network and identity boundaries
- Migration planning and execution — lift-and-shift, re-platform, or rebuild, chosen per workload
- High-availability and disaster-recovery architecture with tested failover, not documented intentions
- Network design: VPC topology, private connectivity, egress control
- Written architecture decision records so the reasoning survives the engagement
- uptime on a globally distributed payment platform
- 99.99%
- application performance improvement after re-architecture
- 30%

Questions
- Do you work with AWS and Azure, or just one?
- Both. Our founder holds AWS Solutions Architect certification and has run production estates on Azure, including Microsoft-stack enterprise environments. We recommend the platform that fits your workload and team, not the one we prefer.
- Can you migrate us without downtime?
- For most workloads, yes. Zero-downtime migration depends on your data layer and how sessions are handled. We assess that first and tell you honestly which components need a maintenance window rather than promising zero and discovering otherwise mid-cutover.
- How long does a typical migration take?
- A single well-understood workload takes weeks. A full estate migration takes months. We scope in phases so value lands early rather than arriving all at once at the end.
