buildOne report1 publisher A DEV Community post explains AWS Lambda Web Functions, which run a plain Node.js HTTP server, and when to use them instead of event-handler Lambdas
AWS Lambda Web Functions let an ordinary Node.js HTTP server run on Lambda, listening on the port in AWS_LAMBDA_HTTP_ENDPOINT, a DEV Community post says. The author says it does not replace event-handler Lambdas and tested it with a streaming agent and simulated high-traffic services.

buildOne report1 publisher OpenSearch Serverless NextGen can sleep after ten idle minutes and takes 10 to 30 seconds to wake
OpenSearch Serverless NextGen, S3 Vectors and DynamoDB vector indexing now all scale to zero on AWS, where OpenSearch's old floor was about $200 a month. A developer who deployed all three from one CDK project says it is hard to look past NextGen.

buildOne report1 publisher Hono apps can run on Lambda Web Functions with no adapter on Node.js 24 and Arm64
AWS Lambda Web Functions run a Hono server without an adapter and allow 128 concurrent requests per environment, a dev.to guide says. Billing, concurrency and endpoint auth differ from Event Functions, so fit needs a check before a backend moves.

buildOne report1 publisher CDK's OAC setup for Lambda function URLs grants CloudFront one of the two permissions it needs
CDK grants CloudFront only one of the two permissions a locked-down Lambda function URL needs, according to an October 2026 update to a dev.to tutorial. The update also moves new functions to Node.js 24, as nodejs20.x lost security patches on 30 April 2026.

buildOne report1 publisher Cloudflare adds on-demand production profiling for Workers and Durable Objects
Cloudflare now lets Workers and Durable Objects users take on-demand CPU and memory profiles in production and view them as flamegraphs. Each capture runs for a window the user sets and can be saved from the CLI to a .pprof file for further analysis.

buildOne report1 publisher Cloudflare's K2 trades a second of produce latency for an event log kept in R2
Cloudflare's K2 streaming beta keeps its event log in R2 object storage at a stated cost of about one second of p99 produce latency. Its case is price and elasticity, so pipelines with many consumers or tight delivery windows have numbers to check before billing starts.

buildConfirmed2 publishers Netlify moved Edge Functions off hosted V8 isolates onto Firecracker MicroVMs in its own network, cutting warm overhead from 25-40 ms to a 5-6 ms median. A dev.to analysis argues that for other edge teams, removing an external network hop can matter as much as a faster runtime.

Cloudflare put Artifacts, a Git platform for AI agents, into open beta with three primitives: repo event subscriptions, Workers bindings and region controls. The detail comes from a third-party dev.to write-up, and its latency and residency claims still need confirming in Cloudflare's documentation.

Google's Cloud Run instances, priced from $5.70 a month, kept an open-source AI agent running with its memory intact in a developer's Preview test. For an agent that mostly waits, it trades a VM's patching for limits the code must be written around.

Cloudflare opened K2, a serverless event log built on R2 object storage, to public beta at about one second of p99 produce latency. For that wait, teams get producers decoupled from consumers and no Kafka cluster of their own to run.

Azure Front Door charges about $205 a month for a terabyte of static files that Cloudflare Workers serves for $0, per a dev.to list-price comparison. Past the included allowance, each paid Azure route bills by the gigabyte, so the service a site ships through puts the same terabyte at about $78 to $205.
