A global media company needs to store petabytes of video content that is frequently accessed by users worldwide. They require extremely low latency for content delivery and high availability. The company also wants to minimize egress costs for global content distribution. Which Google Cloud storage and networking combination should they use?
- ACloud Storage Regional + VPN
- BCloud Storage Multi-Regional + Cloud CDN
- CCloud Storage Coldline + Global External HTTP(S) Load Balancer
- DCloud Storage Nearline + Cloud CDN
Show answer & explanationAnswer & explanation
Correct answer: B. Cloud Storage Multi-Regional + Cloud CDN
Cloud Storage Multi-Regional stores data redundantly across multiple geographic regions, ensuring high availability and low latency access for frequently accessed content globally. Cloud CDN then caches this content at edge locations worldwide, further reducing latency and egress costs for global user access.
Why the other options are wrong
- A. Cloud Storage Regional provides storage in a single region, and VPN is for secure private network connectivity, neither addressing global low-latency content delivery or egress cost optimization.
- C. Cloud Storage Coldline is for data accessed less than once a quarter, which is not suitable for 'frequently accessed' content. Global External HTTP(S) Load Balancer routes traffic but doesn't provide the caching benefits of CDN for static content.
- D. Cloud Storage Nearline is for data accessed less than once a month, not 'frequently accessed' content, making it unsuitable for low-latency user access.
Cloud Storage Multi-Regional + Cloud CDN
A powerful combination for global content distribution, where Multi-Regional storage provides high availability and low latency origin, and Cloud CDN caches content at edge locations to reduce latency and egress costs for users worldwide.
- Multi-Regional: high availability, data distributed globally
- Cloud CDN: caches content at edge locations
- Reduces latency for global users
- Optimizes egress costs for content delivery
Memory trick: Multi-Region Storage + CDN: Global Reach, Fast Delivery, Happy Wallet.
