AWS architecture

Cloud systems built to operate

AWS and hybrid-cloud architecture work across networking, identity, compute, storage, delivery, monitoring, security, and recovery.

01
Traffic boundaries, routing, DNS, and edge entry

Network foundation

Explicit ingress and egress paths, controlled exposure, stable DNS/TLS, and simpler network troubleshooting.

02
Least privilege, temporary access, and auditability

Identity & access

Cleaner permission boundaries, fewer long-lived credentials, and traceable operator access.

App runtime and deployment target

Compute & containers

Workloads that can be deployed, restarted, inspected, and handed over without guesswork.

Observability & response

Correlated telemetry that helps operators understand impact, urgency, likely cause, and next action faster.

Recovery design

Evidence that data and services can be restored within agreed objectives—not only that backup jobs completed.

What a cloud engagement can produce

The goal is not only an AWS diagram. The useful output is a system that can be deployed, monitored, secured, restored, and explained.

01

Cloud readiness review

Map current infrastructure, DNS, SSL, access, backup, deployment, and monitoring gaps before changing systems.

02

AWS deployment blueprint

Create a practical architecture path with network, compute, storage, security, and operations notes.

03

Migration and cutover support

Plan lower-risk movement of websites, apps, storage, DNS, and supporting services into AWS or hybrid cloud.

04

Operations handover

Leave runbooks for deployment, rollback, alerts, backup status, restore steps, and common incident checks.
