How to migrate a monolith to the cloud (without rewriting it)
Rehost the monolith first, fix state and config so it survives the move, and decompose later with the strangler fig if the pain justifies it. Not a rewrite.

How to rightsize cloud resources
A practical rightsizing process: the metrics that reveal oversized instances, the thresholds to act on, and worked numbers on what downsizing saves.
- Security
Cloud IAM best practices: least privilege that actually holds
How to set up cloud IAM properly: least-privilege roles, MFA, SSO, no long-lived keys, service accounts for workloads, and a quarterly audit habit.
- Glossary
Containers & Docker
A container packages an app with everything it needs to run anywhere; Docker made it standard. What that means and why it matters for cloud migration.
- Glossary
IAM (Identity and Access Management)
IAM is the cloud service that controls who can do what in your account. Plain-terms definition, provider names, and why it matters when you migrate.
- Glossary
Infrastructure as Code (IaC)
IaC means defining cloud infrastructure in version-controlled files a tool applies automatically. What it is, the main tools, and why migrations rely on it.
- Glossary
Kubernetes
Kubernetes is the standard system for running containers across many machines. What it does, the managed versions, and whether your migration needs it.

A Step-by-Step Cloud Migration Roadmap (with Checklists)
A phase-by-phase cloud migration roadmap, assess, plan, pilot, migrate, optimize, with a checklist for each phase and realistic timelines.

Lift-and-Shift vs Replatform vs Refactor: The Real Tradeoffs
The three ways to move an app to the cloud, compared on cost, risk, and time-to-value, plus a decision framework and worked numbers for each path.

How to set up a cloud landing zone that stays governable
How to build a landing zone before migrating: multi-account structure, SSO identity, a non-overlapping network, preventive guardrails, and centralized logging.

Should you containerize before migrating? Usually not first
Usually not first. A per-app decision framework for when Docker and Kubernetes pay off, what containerizing really costs, and why migrate-then-containerize wins.

9 ways to avoid cloud bill shock
Nine concrete ways to stop surprise cloud bills: budgets and alerts, egress traps, idle resources, rightsizing, commitments, and dev environments left on.

Secure your first cloud account in an afternoon: the 10-point checklist
Ten controls to set before anything ships in a new AWS, Azure, or GCP account: root lockdown, MFA, least-privilege access, audit logging, blocked public storage, billing alerts.

Autoscaling
Autoscaling adds compute capacity when demand rises and removes it when demand falls, automatically. What it is, how it works, and what it changes when you migrate.
- Glossary
Serverless
Serverless runs your code without any servers to manage, the provider handles capacity and you pay per use. Plain definition, a real example, and migration fit.
- Glossary
Load balancer
A load balancer spreads incoming traffic across multiple servers so one failure never takes you down. Plain definition, a real example, and why it anchors a migration.
