When deploying workloads on Google Cloud Platform (GCP), Managed Instance Groups (MIGs) are one of the most powerful ways to run scalable and resilient applications. While Stateless MIGs are ideal for most scenarios, some applications require persistent state — this is where Stateful MIGs come into play. 🔹 What is a Stateful MIG? A Stateful…
Kubernetes DaemonSet vs Deployment: Key Differences Kubernetes provides multiple ways to run workloads on clusters, with DaemonSet and Deployment being two commonly used controllers. While they may seem similar, they serve different purposes and are optimized for distinct use cases. What is a Deployment? A Deployment in Kubernetes is used to manage a set of…

Reflection allows applications to inspect, analyze, and modify their structure and behavior at runtime. With reflection, we have the ability to discover information about types at runtime. We can think of reflection as a way for a program to look at and inspect itself.Reflection in Swift is implemented using the Mirror API. This API enables…
