A company is experiencing unexpected high costs in their cloud environment, particularly related to data transfer (egress) charges. Upon investigation, they discover that a new application is frequently accessing data stored in a different cloud region than where the application itself is deployed. What is the MOST effective cost optimization strategy to address this specific issue?
- AMigrate the application to a region closer to the data storage.
- BIncrease the instance size of the application servers.
- CUpgrade to premium network connectivity options.
- DImplement a Content Delivery Network (CDN) for all data transfers.
Show answer & explanationAnswer & explanation
Correct answer: A. Migrate the application to a region closer to the data storage.
Cross-region data transfer (egress) is often significantly more expensive than intra-region transfer. Moving the application to the same region as its primary data storage will drastically reduce or eliminate these costly inter-region egress charges.
Why the other options are wrong
- B. Increasing instance size might improve application performance but has no direct impact on data egress costs between regions.
- C. Upgrading network connectivity might improve performance but will likely increase costs, not optimize them, and won't eliminate cross-region egress charges.
- D. CDNs cache static content at edge locations, which might help for external users but is not designed to optimize internal application-to-data transfers between cloud regions.
Cloud Egress Costs
Charges incurred for transferring data out of a cloud provider's network or from one region to another.
- Often a significant and unexpected cloud expense.
- Varies by region and destination.
- Can be optimized by co-locating resources or using CDNs for external delivery.
Memory trick: Data leaving costs money, keep it close.
