From AWS to Google Cloud: A Practical Guide for Cloud Professionals

Designed for seasoned AWS experts, this guide delivers the essential concepts needed to transition to Google Cloud Platform (GCP). It contrasts core services, architectural patterns, and operational models, and provides quick‑reference mappings between AWS and GCP terminologies.

Why Google Cloud?

For more than 15 years, Google has engineered one of the world’s most powerful, scalable cloud infrastructures. Behind popular services such as YouTube, Maps, Gmail, and Search, Google has invested heavily in optimizing its architecture and creating a unified suite of tools. GCP makes these same resources available to customers, offering efficient, high‑performance services backed by Google’s global network.

Regions, Zones, and Points of Presence

Both AWS and GCP deploy resources in geographically distinct regions, each comprising multiple availability zones. While AWS isolates regions to prevent cross‑region outages, GCP’s zones can inter‑communicate when required by service specifications.

Points of Presence (POPs) enhance content delivery by caching data closer to end users. AWS uses POPs for CloudFront, whereas GCP offers Google Cloud CDN and edge‑caching for Cloud Storage and App Engine. GCP’s POPs are connected via Google’s proprietary fiber network, delivering low‑latency, high‑throughput access to all GCP services.

Limits, Accounts, and Pricing

Both platforms impose soft default limits on new accounts to protect against abuse and to provide a manageable learning curve. If your workloads exceed these thresholds, you can request increases through support tickets on both AWS and GCP.

Billing on AWS is organized by accounts and optional sub‑accounts, enabling structured cost allocation across teams. GCP follows a similar model with billing accounts, projects, and sub‑accounts for granular cost control.

Because pricing evolves rapidly, each article focuses on the underlying pricing model rather than static rates. Use the Google Cloud Calculator and the AWS Pricing Calculator to compare real‑time costs for your specific architecture.

Resource Management Interfaces

Both clouds provide a command‑line interface (CLI) and an interactive console:

• Google Cloud: Cloud SDK (gcloud), Cloud Shell (browser‑based terminal), and the Cloud Console.
• AWS: AWS CLI, AWS Management Console, and CloudShell.

All CLIs are cross‑platform (Linux, macOS, Windows) and support scripted automation and infrastructure as code.

Core Service Comparison

Below is a side‑by‑side mapping of AWS and GCP core services:

1. Storage
   • AWS: Amazon EBS, Amazon S3
   • GCP: Google Cloud Storage
2. Compute
   • AWS: Amazon EC2
   • GCP: Compute Engine, App Engine
3. Databases
   • AWS: DynamoDB, RDS
   • GCP: Firestore, Cloud SQL, Bigtable
4. Networking
   • AWS: VPC
   • GCP: VPC

Advanced Service Categories

1. Analytics & Big Data – e.g., Dataflow, Kinesis
2. Application Services – e.g., Pub/Sub, SNS
3. Machine Learning – e.g., AI Platform, SageMaker
4. Management & Monitoring – e.g., Stackdriver, CloudWatch
