GOOGLE CLOUD VS AMAZON CLOUD VS MICROSOFT AZURE

• The general purpose AWS SSD offers 10,000 IOPS. With maximum IOPs up to 65,000, provisioned IOPs could offer up to 20,000 IOPs per volume.  While relatively speaking, Azure offers 5,000 IOPs, Google on the other hand not only offers the highest IOPs, but also gives customers the most choice in the size of block storage volumes. For more traditional hard-drive based storage, Google offers volume sizes ranging from 1GB to 64TB. AWS offers volumes between 500GB to 16TB. Azure offers between 1GB and 1TB volume sizes. Talking of Solid State Disks or SSDs, Google generously offers the highest level of IOPs-per-volume in HDDs, approx.. 3,000 for reads and 15,000 for writes. AWS and Azure are at 500 max IOPs per volume.  Max output ranges from Azure are 60 MBps to Google at 180 for read and 120 for write. AWS is at 500 MBps.
• Pricing have always been problematical issue (all prices are per GB/month), starting at $ 0.045 for HHD, AWS while it is $0.04 for Google and $0.03 for Azure. Depending on the size of the disk SSD starts its pricing at $0.10 in AWS, $0.17 for Google and Azure is between $0.12 and 0.14.

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

• The Globally Redundant Storage read only storage for $0.046 offered by Azure which means write changes is not possible, but on the for single-region storage for $0.0184 the latter is expensive.

 “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.”
