The estate's transaction logging wrote to blob storage through a dedicated logging function - which consumers located through the same Key Vault registry the logger belongs to. Discovery consuming discovery, the transaction-id thread that made it useful, and the bootstrap questions self-reference always raises. Part 6 of Service Discovery Without a Service Mesh.
One static registration method wires the whole discovery subsystem into an Azure Functions host, and one CI pipeline packs it as a private NuGet package. The lifetime choices in those few lines quietly decide the caching semantics of the entire estate - and a duplicate registration teaches how DI forgives. Part 5 of Service Discovery Without a Service Mesh.
Azure Functions want their key in an x-functions-key header; Logic App workflows want a SAS signature in the query string. How a discovery record's type field became a calling-convention discriminator, and how one small HTTP service hid that difference from every caller in the estate. Part 3 of Service Discovery Without a Service Mesh.
Dozens of Azure Functions and Logic Apps need each other's URLs and keys, and there is no Kubernetes, no sidecar, no mesh to hand them out. How a small .NET library turned one Key Vault and a naming convention into a working discovery layer - the consumer side of a registry made of secrets. Part 1 of a new series.
Reading the Function App module against its App Service sibling: the shared secure-hosting chassis, the runtime storage account and version knobs that are genuinely new, and what half-populated prod values teach about templates.
The honest ledger for the whole estate - what coordinating through tables actually cost, what genuinely earned its keep, and what I would reach for now instead of using the database as a message bus.
Four pipelines run dotnet test against projects with no tests and pass every time, the shared model ships as committed .nupkg files in a folder, one executable has no pipeline at all, and a DLL with no source hides an algorithm pasted inline elsewhere.
UTC timers, IST badge gates, DateTime.Now in one executable and UtcNow in the next, columns that record neither - how a system whose entire product is timestamps got away with never deciding what time it is.
Every five minutes a function hunts for people still virtually swiped in past ten hours and emails them - magic node numbers, an at-most-once flag with a gap in it, and a local config file pointing straight at production.
The leave sync resumes from wherever its own job log last said Success - one table serving as log, watermark and metrics store at once, with recursive pagination on top and an envelope check in exactly the wrong place.
Leave records arrive late, change and get cancelled - so the sync reaches back into already-approved attendance rows and re-derives them, carefully stepping around human decisions and allowance money.
A daily Azure Function mirrors the HR system's employee master into the attendance database - a field-by-field upsert, a clever delegation rule, a vestigial handshake, and the parse calls that can kill the whole run.
Five executables, zero queues - how an attendance platform coordinated a web app, three Azure Functions and a console job through one SQL database, and what that choice bought and cost. Part 1 of the series.
