Serverless Security on GCP: IAM, VPC Connector, and Secret Manager

Serverless doesn't mean security-free. Cloud Run and Cloud Functions have an IAM model, network configuration, and secret handling that require explicit attention. This guide secures serverless workloads end-to-end: identity, network isolation, secret injection, and audit logging.

Cloud Run Concurrency, Cold Starts, and Performance Tuning

Cloud Run's performance characteristics are often misunderstood. This guide explains how concurrency settings, CPU allocation modes, startup probes, and container optimization interact to determine your service's actual latency and scaling behavior.

GCP Cloud Billing Best Practices: Labels, Budgets, and Cost Allocation

Cloud billing surprises are almost always a labeling and visibility problem. This guide walks through Google Cloud's full billing stack — labels, budgets, billing export to BigQuery, and chargeback models — so you can see exactly where every dollar goes and alert before a runaway job drains the budget.

Google Cloud FinOps: A Complete Guide to Committed Use Discounts

Committed Use Discounts (CUDs) can reduce GCP compute costs by 37-70% for predictable workloads. This guide covers resource-based and spend-based CUDs, analyzing your workload for CUD eligibility, purchasing strategy, and tracking CUD utilization in BigQuery billing exports.

Cloud Run vs Cloud Functions vs App Engine: Choosing the Right GCP Serverless Platform

GCP offers three serverless compute platforms, each with a different operational model and set of trade-offs. This guide compares Cloud Run, Cloud Functions, and App Engine across cold start behavior, pricing, scaling, and workload fit to help you pick the right platform.

Google Cloud Networking Deep Dive: VPC, Load Balancers, and CDN

GCP networking differs fundamentally from AWS and traditional data center networking. This guide covers GCP VPC architecture, subnet design, routing, Cloud Load Balancing tiers, Cloud CDN for global content delivery, and hybrid connectivity with Cloud Interconnect and VPN.

GCP Rightsizing Guide: Optimizing Compute Engine, GKE, and Cloud SQL

Rightsizing is the single highest-ROI cloud optimization activity. Most GCP workloads run on machines that are 2-3x larger than necessary, paying for CPU and memory that sits idle. This guide covers systematic rightsizing for Compute Engine VMs, GKE node pools, and Cloud SQL instances using real utilization data.
