Notes on data, AI, IT
and security
No marketing fog. The way I think about real problems with founders and managers.
OpenStack and private cloud: who gains leverage, and who just sinks in complexity
The real cost of running your own cloud infrastructure is processes, scale, and people - not just hardware.
API-first inside the company: why integrations should not happen by word of mouth
How to agree on system interfaces before integration chaos becomes the norm, and why this matters for a growing company.
Failure as a management scenario: who decides in the first 30 minutes
On why a technical incident is not only an engineering problem, and how to define roles, escalation paths, and a single source of truth before something breaks.
Public cloud SLA: what it says and what it does not
A breakdown of where the provider's responsibility ends and the customer's begins - and why this matters before an incident, not after.
Backup after virtualisation: why old schemes no longer hold
Having backup copies and being able to restore from them are two different things. Virtualisation changes both, and old backup approaches often create the illusion of protection where there is none.
Virtualisation is not the cloud: where the practical boundary lies
A hypervisor makes servers more flexible, but it does not make infrastructure service-oriented. The difference between virtualisation and cloud, and why it matters for business decisions.
Open data and APIs: why your company should think like a platform now
An API is not a trendy interface and not a way to look technical. It is an integration discipline that determines how easily your systems will work together a year from now.
Own datacenter, hosting, or cloud: count speed of change, not servers
How to move the infrastructure conversation from hardware costs to speed of response, SLA, and clear ownership of responsibility.
