Hence, “Azure has the best price/performance ratio for block storage. But, for workloads that require higher IOPs, Google becomes the more cost-effective option”.
OBJECT STORAGE :-
Object storage is the service which enables the user to put a file in the cloud. Simple Storage Service (S3) is primary object storage platform offered by Amazon Web Services, which enables Standard-Infrequent Access for cool storage and Glacier for cold storage. Google has Google Cloud Storage, GCS Nearline for cool storage and GCS Coldline for the purpose of records. With a hot and cool option with Azure Hot and Cool Storage Blobs; customers have a choice to use the cool storage for archival data. With a 5TB object size limit each for AWS and Google, Azure offers a 500TB per account limit. AWS and Google each publicize 99.999999999% durability for objects stored in their cloud. Azure does not publish durability service level agreements.
S3 costs $0.023 in AWS; to replicate data across multiple regions costs twice as much: $0.046, plus a $0.01 per GB transfer fee. (all prices are in GB/month) Most analogous offerings is from Google: It is a single-region storage that costs $0.02, while multi-region with free data transfer is at $0.026
“Based on these pricing scenarios, Google has the least expensive pure object storage costs, plus the free transfer of data. AWS, however, beats Google on cold storage costs.”
