Cloud storage is a model of computer data storage in which the digital data is stored in logical pools. The physical storage spans multiple servers (sometimes in multiple locations), and the physical environment is typically owned and managed by a hosting company. These cloud storage providers are responsible for keeping the data available and accessible, and the physical environment protected and running. People and organizations buy or lease storage capacity from the providers to store user, organization, or application data.

Cloud storage services may be accessed through a colocated cloud computing service, a web service application programming interface (API) or by applications that utilize the API, such as cloud desktop storage, a cloud storage gateway or Web-based content management systems.

Blob Storages (3)

Simple, distributed managed storages for unstructured data of all sizes.

[AWS] Simple Storage System (Amazon S3)
Provides object storage through a web service interface.
Amazon S3 or Amazon Simple Storage Service is a service offered by Amazon Web Services (AWS) that provides object storage through a web service interface. Amazon S3 uses the same scalable storage infrastructure that Amazon.com uses to run its global e-commerce network. Amazon S3 can be employed to store any type of object which allows for uses like storage for Internet applications, backup and recovery, disaster recovery, data archives, data lakes for analytics, and hybrid cloud storage. AWS launched Amazon S3 in the United States on March 14, 2006, then in Europe in November 2007.

[Google Cloud] Storage
A RESTful online file storage web service for storing and accessing data on Google Cloud Platform infrastructure.
Google Cloud Storage is a RESTful online file storage web service for storing and accessing data on Google Cloud Platform infrastructure. The service combines the performance and scalability of Google's cloud with advanced security and sharing capabilities. It is an Infrastructure as a Service (IaaS), comparable to Amazon S3 online storage service. Contrary to Google Drive and according to different service specifications, Google Cloud Storage appears to be more suitable for enterprises.

Managed Persistent Disks (block-level volumes) (3)

Block-level storage volumes that are managed by a cloud provider and used with Virtual Machines (e.g. standard or SSD persistent disks).

[AWS] Elastic Block Store (EBS)
Provides raw block-level storage that can be attached to Amazon EC2 instances and is used by Amazon Relational Database Service (RDS).
Amazon Elastic Block Store (EBS) provides raw block-level storage that can be attached to Amazon EC2 instances and is used by Amazon Relational Database Service (RDS). Amazon EBS provides a range of options for storage performance and cost. These options are divided into two major categories: SSD-backed storage for transactional workloads, such as databases and boot volumes (performance depends primarily on IOPS), and disk-backed storage for throughput intensive workloads, such as MapReduce and log processing (performance depends primarily on MB/s).

[Google Cloud] Persistent Disk
Durable and high performance block storage for Google Cloud Platform.
Google Persistent Disk is durable and high performance block storage for Google Cloud Platform. Persistent Disk provides SSD and HDD storage which can be attached to instances running in either Compute Engine or Google Kubernetes Engine. Storage volumes can be transparently resized, quickly backed up, and offer the ability to support simultaneous readers.

[Azure] Managed Disks
Durability, scalability, availability, and security for data — from test scenarios to mission-critical workloads.
Get the durability, scalability, availability, and security you need for all of your data—from test scenarios to mission-critical workloads. Use Azure Ultra Disk Storage when you need sub-millisecond latency and extremely scalable performance, Azure Premium SSD for production workloads, and Azure Standard SSD for cost-effective and consistent performance.

File Storage Services (3)

Managed file storage services for applications that require a filesystem interface and a shared filesystem for data.

[AWS] Elastic File System (EFS)
A cloud storage service provided by Amazon Web Services (AWS) designed to provide scalable, elastic, concurrent with some restrictions, and encrypted file storage for use with both AWS cloud services and on-premises resources.
Amazon Elastic File System (Amazon EFS) is a cloud storage service provided by Amazon Web Services (AWS) designed to provide scalable, elastic, concurrent with some restrictions, and encrypted file storage for use with both AWS cloud services and on-premises resources. Amazon EFS is built to be able to grow and shrink automatically as files are added and removed. Amazon EFS supports Network File System (NFS) versions 4.0 and 4.1 (NFSv4) protocol, and control access to files through Portable Operating System Interface (POSIX) permissions.

[Google Cloud] Filestore
A managed file storage service for applications that require a filesystem interface and a shared filesystem for data.
Cloud Filestore is a managed file storage service for applications that require a filesystem interface and a shared filesystem for data. Filestore gives users a simple, native experience for standing up managed Network Attached Storage (NAS) with their Google Compute Engine and Kubernetes Engine instances. The ability to fine-tune Filestore’s performance and capacity independently leads to predictably fast performance for your file-based workloads.

Archival Storages (3)

For storing rarely accessed data (high durability, low price, e.g. for $1 per terabyte per month).

[AWS] Glacier
Amazon S3 Glacier & S3 Glacier Deep Archive.
Amazon S3 Glacier and S3 Glacier Deep Archive are a secure, durable, and extremely low-cost Amazon S3 cloud storage classes for data archiving and long-term backup. They are designed to deliver 99.999999999% durability, and provide comprehensive security and compliance capabilities that can help meet even the most stringent regulatory requirements. Customers can store data for as little as $1 per terabyte per month, a significant savings compared to on-premises solutions. To keep costs low yet suitable for varying retrieval needs, Amazon S3 Glacier provides three options for access to archives, from a few minutes to several hours, and S3 Glacier Deep Archive provides two access options ranging from 12 to 48 hours.

[Google Cloud] Archival Storages
Nearline (month), Coldline (quarter), Archive (long-term)
Nearline, Coldline, and Archive offer ultra low-cost, highly-durable, highly available archival storage. For data accessed less than once a year, Archive is a cost-effective storage option for long-term preservation of data. Coldline is also ideal for cold storage—data your business expects to touch less than once a quarter. For warmer storage, choose Nearline: data you expect to access less than once a month, but possibly multiple times throughout the year. All storage classes are available across all GCP regions and provide unparalleled sub-second access speeds with a consistent API.

[Azure] Archive Storage
Access tiers include: Hot (accessed frequently), Cool (30+ days), Archive (180+ days).
Azure storage offers different access tiers, which allow you to store blob object data in the most cost-effective manner. The available access tiers include:

Hot - Optimized for storing data that is accessed frequently. Cool - Optimized for storing data that is infrequently accessed and stored for at least 30 days. Archive - Optimized for storing data that is rarely accessed and stored for at least 180 days with flexible latency requirements (on the order of hours). The following considerations apply to the different access tiers:
