Cloud Storage Information:
Cloud storage is a model of data storage in which the digital data is stored in logical pools, physical storage spans multiple servers, 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 co-located cloud computer service, a web service application programming interface or by applications that utilize the API, such as cloud desktop storage.
|Cloud Storage Information|
Cloud storage is based on highly visualized infrastructure and is like broader cloud computing in terms of accessible interfaces, near-instant elasticity and sociability, multi-tenancy, and metered resources. Cloud storage services can be utilized from an off-premises service (Amazon S3) or deployed on-premises,
- Made up of many distributed resources, but still acts as one, either in a federated or a cooperative storage cloud architecture
- Highly fault tolerant through redundancy and distribution of data
- Highly durable through the creation of versioned copies
- Typically eventually consistent with regard to data replicas
- Security of stored data and data in transit may be a concern when storing sensitive data at a cloud storage provider,
- 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. For instance, the U.S. Department of Defense designated the Defense Information Systems Agency to maintain a list of records management products that meet all of the records retention, personally identifiable information, and security requirements.
- 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 file sharing. For example, the Codex Cloud E book storage site has faced litigation from the owners of the intellectual property uploaded and shared there, as have the Groove Shark and YouTube sites it has been compared to.
- The legal aspect, from a regulatory compliance standpoint, is of concern when storing files domestically and especially internationally.
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. Companies can
- Go bankrupt.
- Expand and change their focus.
- 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.
- Suffer an irrecoverable disaster
