Hello #infosec 👋 I'm Richard — Solution Architect, ~30 yrs of .NET, now mostly Azure security & architecture in the insurance world. Took the scenic route: began servicing semiconductor lithography kit for Canon across Europe before falling into code. I care about secure-by-design and the gap between "compliant" and actually secure. West Wales 🏴󠁧󠁢󠁷󠁬󠁳󠁿 based; you'll find me on a beach, at the erg, or buried in 300+ vintage sci-fi novels. Mostly here to learn. #introduction #cloudsecurity #azure

🆕 The distributed systems tax Every time you turn a function call into a network call, you start paying a tax. Worth it sometimes — but know the bill before you sign up. Read it → https://rj-cooper.co.uk/posts/the-distributed-systems-tax/ #Architecture #Microservices #Monolith

🆕 Modular microliths

The microservices-versus-monolith war is tired. The systems I've actually shipped are usually a bit of both — and on purpose.

🆕 Anti-corruption layers work both ways An anti-corruption layer is sold as a wall against a vendor's mess. It's really a double-sided socket — the same seam lets you swap either side independently.

🆕 The myth of the 'right' architecture There's no 'right' architecture to find and lock in — only one that fits the forces on you now. The real job is keeping it able to change when they shift.

🆕 The last responsible moment Deferring a decision isn't dodging it. The last responsible moment is the point past which waiting costs you an option — so decide then, not before, not after. Read it → https://rj-cooper.co.uk/posts/the-last-responsible-moment/ #Architecture #Decisionmaking
