Notes on data, AI, IT
and security
No marketing fog. The way I think about real problems with founders and managers.
API gateway: a team contract, not just a routing tool
Most API gateway conversations stay at the infrastructure level. The part that actually matters is what it forces teams to agree on before they write a line of code.
Microservices and teams: why a service boundary is a responsibility boundary
Moving to microservices changes not just the architecture, but how teams negotiate contracts with each other.
Containers in enterprise: where the pilot ends and the platform begins
Docker and containerisation have moved from hype to real deployments. I look at what it takes for a pilot to become an infrastructure platform.
Shadow SaaS subscriptions: a management risk that grows quietly
Employees connect cloud services without telling IT. I look at why this has become a systemic problem and how to manage it.
Technical debt: it is an ownership question, not a metaphor
Technical debt gets discussed as a technical concept. For leadership it is first and foremost a question of who makes decisions and lives with the consequences.
Microservices: the management cost nobody talks about
Moving to microservices is not purely a technical decision. It introduces real operational load on the organisation that rarely appears in the pitch.
Lift-and-shift cloud migration: what is hidden in the bill
Why moving applications to the cloud without rearchitecting often costs more than expected, and what to examine before starting a migration.
DevOps is not a toolset, it is a culture change
Why companies that implement DevOps as a technology end up with expensive tools instead of faster releases - and where the real lever is.
API gateway: a single entry point as operational discipline
Why an API gateway matters not just to developers but to anyone managing integrations, security, and operational costs.
Kubernetes 1.0: container orchestration as the new operational normal
What the Kubernetes 1.0 release changes for production platforms, team responsibilities, and how companies run software.
Cloud costs: discipline matters more than scale
Why cloud bills start surprising companies long before any real scale arrives - and how to prevent it.
Microservices are not a free lunch
What a manager needs to know about the real trade-offs of microservice architecture before the team starts building it.
