Reliable Serverless **Rating:** 5.0/5.0 stars **Reviewed by:** Verified User in Computer Software | Small-Business (50 or fewer emp.) **Reviewed Date:** May 16, 2023 **What do you like best about Azure Functions?** We rely on Azure Functions a lot in our day-to-day, especially for async processing, webhooks, and real-time triggers across our hybrid cloud setup. What makes it a strong tool is how easily it connects with the rest of Azure. You can plug it into Event Grid, Service Bus, or Cosmos DB in no time. No need to write a bunch of boilerplate. Just wire it up and go. That kind of integration saves serious time during builds. Getting started was smooth. We had our first function apps live in production within a couple of days.The triggers and bindings take care of most of the boring setup, so you can focus on writing actual code. It runs smoothly with both Python and .NET. Terraform works well too, letting us keep track of changes and handle rollbacks without headaches. When it comes to features, it covers everything you need HTTP calls, queue processing, timers, storage events. Scaling happens automatically and is pretty reliable. Cold starts used to be rough but have gotten much better lately, even on the cheaper consumption plan. We did run into a surprise with costs once. One of our functions got stuck retrying over and over, which blew up usage. Microsoft support jumped on it quickly, helped us find the misconfiguration, and got it fixed fast with no hassle. We use Azure Functions every single day. It runs background jobs, triggers event flows, and ties together a lot of our backend systems. It’s part of our standard toolkit now. **What do you dislike about Azure Functions?** The main pain point has been cold starts, especially on the Consumption plan when running Python or Node.js for workloads where low latency matters. **What problems is Azure Functions solving and how is that benefiting you?** We’ve been leaning on Azure Functions for our backend ops, lightweight, serverless, and does the job without needing a full blown container standing by. For website perf checks with Puppeteer, it’s been rock solid. Spawns fast, grabs the page, pulls the HAR file, and dumps all the timing and size metrics. Perfect for flagging resource bottlenecks and render blockers. We also use it to probe remote ports and check service health, basically a stealth ops bot that runs on schedule or trigger. Multi region deploys let us run tests from edge locations so we can debug region specific issues. It’s smooth with both Linux and Windows runtimes, so whether Puppeteer needs headless Chrome or we’re doing socket-level scans, it doesn’t choke. Scaling is auto magical. One second you're running a few probes, next second you're spawning 100 checks. We spin up Azure Functions in multiple data centers worldwide so our apps run faster and stay close to users in each region. Having both Linux and Windows support makes life way easier on the ops side. Also, the way Azure handles memory beats out other serverless setups like Firecracker, which gives us a smoother, more solid environment to run our workloads without surprises. ### 12.
