What IT Teams Should Know Before Deploying Unified Communications

What can cause a unified communications rollout to go off track even when the initial project plan looks straightforward? Deploying unified communications may sound simple in a kickoff meeting, but in practice, it can be one of the more deceptively complex infrastructure projects an IT team can take on because it affects nearly every department at once. Network capacity, licensing, integrations, security, user adoption, and compliance requirements can all create problems if they aren't addressed early.

Your Observability Stack Found the Fire. Congratulations.

The dashboards are red, the alerts are firing, and Slack has officially become a war room. Someone has asked, “Anyone else seeing this?” and 14 people have immediately responded with screenshots. Welcome to another day in distributed systems. The recent GitHub outage is a great reminder of how complicated modern applications have become. Services talk to services, infrastructure scales up and down, retries multiply traffic, and dependencies behave in ways nobody expected.

The Compounding Platform Tax

Private cloud and on-premises infrastructure are different. I know this. I used the terms interchangeably anyway because I was trying to compress a pattern into one sentence. That was sloppy, but the underlying pattern still matters. Banks run Kubernetes differently from most other organizations. Not because every bank makes the same choices, but because similar constraints can produce a similar pattern.

Comparing Load Testing Tools for CI/CD Pipelines: 2026 Guide to Choosing the Right Fit

Selecting load testing tools for your CI/CD pipeline is a lot like picking between a scalpel and a Swiss Army knife. A scalpel – the focused, specialized solution – excels at one job with surgical accuracy. Think of Apache JMeter or Gatling: these tools are designed for deep, targeted testing, offering powerful scripting and low-level protocol support. They let you dial in precise scenarios and slice through performance bottlenecks with fine control.

Self-hosted OTA for an hour a month

If you are a React Native engineer, your job isn’t typically about maintaining infrastructure. So “self-hosted OTA” can sound like a trap. Even if your Expo Update bill is hitting six figures, it’s easy to assume that self-hosting isn’t worth the potentially huge time sink. That fear is understandable, but it doesn’t have to play out that way.

Break One Dependency, Not The Whole Cluster

Scoped chaos rules are now in proxymock. A filter query picks the traffic, an effect perturbs it, and every response that gets touched is labelled so you can tell an injected failure from a real one for the rest of the run. Available in v2.5.892 and newer. The short version of why: kill a pod and you learn something real, but you do not learn what your service does when a dependency stays up and starts lying to it.

Application Level Dependency Chaos Testing

Somewhere in your service is a branch that has never executed. Not a rare one, a never one. It handles a dependency being unavailable: it reads from a cache, it returns a stale value, it marks the response degraded so callers know not to trust it too far. It was written carefully. It was reviewed. Whether it works is an open question, because nothing in the test suite makes that dependency fail, and the dependency does not fail on request.

I built an API traffic classifier for business workflows

An engineering leader asked me a question a few weeks ago: could we read their business workflows out of API traffic instead of asking people to document them? I said it should be possible. Then I tried it. A few engineers know how the system really works. They know which calls make up a work order and which checks happen after a write. That stuff rarely makes it into the test plan. Usually it’s in somebody’s head. Sometimes it’s in several heads, with slightly different answers.

Designing scalable OTA update architecture for React Native

Self-hosting OTA updates became common after App Center and CodePush shut down in 2025. CodePush had been the popular free option, but the remaining hosted services easily hitting five or six figure bills for popular apps. For staging-only or use with small user bases, self-hosting is fairly straight forwards. But, as the user base grows, the architecture can start to struggle and bolt on pieces are required.
