21. Cloud Storage – Storage-as-a-Service Cloud storage is a service model in which data is transmitted and stored on remote storage systems, where it is maintained, managed, backed up and made available to users over a network -- typically, the internet. Users generally pay for their cloud data storage on a per-consumption, monthly rate. Cloud service providers manage and maintain data transferred to the cloud. Storage services are provided on demand in the cloud, with capacity increasing and decreasing as needed . Organizations opting for cloud storage eliminate the need to buy, manage and maintain in-house storage infrastructure. cloud storage options : Public cloud.  Private cloud. Hybrid cloud

22.  cloud storage options Public cloud .   These storage services provide a multi-tenant storage environment that is most suited for unstructured data on a subscription basis. Data is stored in the service provider's data centers with storage data spread across multiple regions or continents. Customers generally pay on a per-use basis, similar to the utility payment model. In many cases, there are also transaction charges based on frequency and the volume of data being accessed. This market sector is dominated by the following services: Amazon Simple Storage Service ( S3 ); Amazon Glacier  for deep archival or cold storage; Google Cloud Storage ; Google Cloud Storage Nearline  for cold data; and Microsoft Azure .

23. Private cloud .  A private cloud storage service is an in-house storage resource deployed as a dedicated environment protected behind a firewall. Internally hosted private cloud storage implementations emulate some of the features of commercial public cloud services, providing easy access and allocation of storage resources for business users, as well as object storage protocols. Private clouds are appropriate for users who need customization and more control over their data or who have stringent data security or regulatory requirements.

24. Hybrid cloud .  This cloud storage option is a mix of private cloud storage and third-party public cloud storage services, with a layer of orchestration management to operationally integrate the two platforms. The model offers businesses flexibility and more data deployment options. An organization might, for example, store actively used and structured data in an on-premises private cloud and unstructured and archival data in a public cloud. A hybrid environment also makes it easier to handle seasonal or unanticipated spikes in data creation or access by  cloud bursting  to the external storage service and avoiding having to add in-house storage resources.

25. How does cloud storage work? Cloud service providers maintain large data centers in multiple locations around the world. When customers purchase cloud storage from a provider, they turn over most aspects of the data storage to the vendor, including security, capacity, storage servers and computing resources, data availability and delivery over a network. Customer applications can access the stored cloud data through traditional storage protocols or application programming indicators (APIs), or they can also be moved to the cloud. How cloud storage works varies depending on the type of storage used. The three main types are  block storage ,  file storage  and  object storage :

26. Block storage  divides large volumes of data into smaller units called  blocks . Each block is associated with a unique identifier and placed on one of the system's storage drives. Block storage is fast, efficient and provides the low latency required by applications such as databases and high-performance workloads. File storage  organizes data in a hierarchical system of files and folders; it is commonly used with personal computer storage drives and network-attached storage (NAS). Data in a file storage system is stored in files, and the files are stored in folders. Directories and subdirectories are used to organize the folders and locate files and data. A file storage-based cloud can make data access and retrieval easier, with this hierarchical format being familiar to users and required by some applications.

27. Object storage  stores data as objects, which consist of three components: data stored in a file, metadata associated with the data file and a unique identifier. Using the  RESTful API , an object storage protocol stores a file and its associated metadata as a single object and assigns it an identification (ID) number. To retrieve content, the user presents the ID to the system and the content is assembled with all its metadata, authentication and security. Object-based storage systems allow metadata to be customized, which can streamline data access and analysis. With object storage, data can be stored in its native format with massive scalability.

28. Advantages of Cloud Storage

29. uses for cloud storage are cloud backup disaster recovery  (DR) archiving infrequently accessed data Cloud storage service providers: Amazon Web Services, Google and Microsoft Azure, but traditional storage vendors like Dell EMC, Hewlett Packard Enterprise, Hitachi Data Systems,  IBM  and NetApp also operate in the space with products for both enterprise and small business owners that include  self-service cloud portals  to provision and monitor use. online file storage services Box and Dropbox, have business-to-consumer (B2C) cloud storage services, as well as business-to-business (B2B) offerings.

30. S3 Amazon S3  (Simple Storage Service) is a scalable, high-speed, low-cost web-based service designed for online backup and archiving of data and application programs. It allows to upload, store, and download any type of files up to 5 TB in size . This service allows the subscribers to access the same systems that Amazon uses to run its own web sites. The subscriber has control over the accessibility of data, i.e. privately/publicly accessible. Amazon S3’s storage units are objects that are organized into buckets . Buckets are used to organize files, like a folder . An infinite amount of data can be stored in buckets. There is no limit on the number of objects that can be uploaded and each object can contain up to 5 TB of data.

31. Amazon S3 is a program that’s built to store, protect, and retrieve data from “buckets ” at any time from anywhere on any device .  Organizations of any size in any industry can use this service. Use cases include websites, mobile apps, archiving, data backups and restorations, IoT devices, enterprise application storage, and providing the underlying storage layer for your data lake. Amazon S3 focuses on two key components: buckets and objects that work together to create the storage system. objects are data files, including documents, photos, and videos . Each object is identified by a unique key within the S3 environment that differentiates it from other stored objects. The maximum object file size is 160 GB for uploading, however there are various AWS tools to help you add files larger than this
