Jump to navigation Jump to search This article is about enterprise-level cloud data storage. For consumer-level file hosting services, see file hosting service. Cloud storage is a model of computer data storage in which the digital data is stored in logical pools. Cloud computing is believed to have been invented by Joseph Carl Robnett Licklider in the 1960s with his work on ARPANET to connect people and data from anywhere at any time. The storage was one of the first to be all web-based, and referenced in their commercials as, “you can think of our electronic meeting place as the cloud.
A high level architecture of cloud storage. This section may be too technical for most readers to understand. Please help improve it to make it understandable to non-experts, without removing the technical details. Cloud storage is based on highly virtualized infrastructure and is like broader cloud computing in terms of accessible interfaces, near-instant elasticity and scalability, multi-tenancy, and metered resources. Cloud storage typically refers to a hosted object storage service, but the term has broadened to include other types of data storage that are now available as a service, like block storage. Companies need only pay for the storage they actually use, typically an average of consumption during a month. This does not mean that cloud storage is less expensive, only that it incurs operating expenses rather than capital expenses.
Also at the vendor level they are dealing with higher levels of energy so they will be more equipped with managing it in order to keep their own costs down as well. Storage availability and data protection is intrinsic to object storage architecture, so depending on the application, the additional technology, effort and cost to add availability and protection can be eliminated. Storage maintenance tasks, such as purchasing additional storage capacity, are offloaded to the responsibility of a service provider. Cloud storage provides users with immediate access to a broad range of resources and applications hosted in the infrastructure of another organization via a web service interface. Cloud storage can be used for copying virtual machine images from the cloud to on-premises locations or to import a virtual machine image from an on-premises location to the cloud image library. In addition, cloud storage can be used to move virtual machine images between user accounts or between data centers. Cloud storage can be mapped as a local drive with the WebDAV protocol.

Outsourcing data storage increases the attack surface area. When data has been distributed it is stored at more locations increasing the risk of unauthorized physical access to the data. For example, in cloud based architecture, data is replicated and moved frequently so the risk of unauthorized data recovery increases dramatically. Such as in the case of disposal of old equipment, reuse of drives, reallocation of storage space. The manner that data is replicated depends on the service level a customer chooses and on the service provided.
It increases the number of networks over which the data travels. Sometimes because of erroneous actions, faulty equipment, a bug and sometimes because of criminal intent. This risk applies to all types of storage and not only cloud storage. The risk of having data read during transmission can be mitigated through encryption technology. Encryption in transit protects data as it is being transmitted to and from the cloud service.
Companies are not permanent and the services and products they provide can change. Outsourcing data storage to another company needs careful investigation and nothing is ever certain. Contracts set in stone can be worthless when a company ceases to exist or its circumstances change. Be purchased by other larger companies. Be purchased by a company headquartered in or move to a country that negates compliance with export restrictions and thus necessitates a move.
Reliability and availability depends on wide area network availability and on the level of precautions taken by the service provider. Reliability should be based on hardware as well as various algorithms used. Its a given a multiplicity of data storage. Users with specific records-keeping requirements, such as public agencies that must retain electronic records according to statute, may encounter complications with using cloud computing and storage.
Cloud storage is a rich resource for both hackers and national security agencies. Because the cloud holds data from many different users and organizations, hackers see it as a very valuable target. Piracy and copyright infringement may be enabled by sites that permit filesharing. The legal aspect, from a regulatory compliance standpoint, is of concern when storing files domestically and especially internationally. Increase Your 100’s Storage with 128K from Compuserve”.
