Descriptions

Google Cloud Storage

Google Cloud Platform (GCP) has proven itself time over time. They host anything, from very small startups to large enterprise clients, like Nintendo’s Pokemon GO, or basically any NFT marketplace.

Google Cloud Storage was first to introduce Interconnect.

Google Cloud Storage Interconnect facilitates cheap egress costs, from the storage to your CDN supplier. Which means that, when you put a CDN in front of your google cloud object storage, the egress traffic (from google to the CDN) will either be cheap or even free. Essentially, since you’re paying for the bandwidth on the CDN side as well, saving you money on needless costs.

Amazon S3

World’s biggest Cloud Storage Provider. Amazon, traditionally an online book store, has put a target on the cloud compute space when it shifted its focus to Amazon Web Services (AWS) in 2006. E-Commerce competition was tough, but public cloud companies back then were scarce, and usability and user friendly products were a long way from being invented.

Amazon’s reign on cloud computing has left its mark in public cloud-land. Competitors have trouble keeping up, if they even get to a point of feature-parity at all. With Amazon’s S3 storage being one of the first, it has basically dictated a standard for the public cloud’s blob storage protocol.

Needless to say, Amazon invented the S3 (Simple Storage Service) standard.
