Google Cloud Digital LeaderDigital transformation with Google CloudHard
A global e-commerce giant is experiencing unprecedented traffic spikes during seasonal sales events, leading to performance degradation and customer dissatisfaction with their monolithic on-premises application. They want to digitally transform by migrating to Google Cloud, adopting a microservices architecture, and ensuring their application can automatically scale to handle extreme loads with high availability and fault tolerance across multiple regions. Which architectural pattern and Google Cloud foundational service would best address their high-scale, global availability, and fault tolerance requirements?
- AMonolithic architecture with Compute Engine instances in a single region.
- BMicroservices architecture deployed on Google Kubernetes Engine (GKE) across multiple regions.
- CServerless functions with Cloud Functions in a single zone.
- DRelational database with Cloud SQL and manual load balancing.
Show answer & explanationAnswer & explanation
Correct answer: B. Microservices architecture deployed on Google Kubernetes Engine (GKE) across multiple regions.
A microservices architecture breaks down the monolithic application into smaller, independent services, which improves scalability and fault tolerance. Deploying these on GKE allows for container orchestration, automatic scaling, and high availability across multiple regions, directly addressing the extreme load and global availability requirements.
Why the other options are wrong
- A. Monolithic architecture is the current problem. Single region deployment lacks global availability and fault tolerance.
- C. While serverless functions are scalable, a complex e-commerce platform might exceed the scope of purely functional deployment, and a single zone lacks high availability and global reach.
- D. Cloud SQL is for databases, not application hosting, and manual load balancing is inefficient for extreme, unpredictable traffic.
GKE for Microservices
Google Kubernetes Engine (GKE) provides a managed environment for deploying, managing, and scaling containerized applications, ideal for microservices architectures.
- Automated deployment, scaling, and management of containers.
- Supports high availability and multi-regional deployments.
- Integrates with other Google Cloud services for storage, networking, and monitoring.
Memory trick: GKE + Microservices: Global scale, Kubernetes manages, always available.
