Cloud Database Storage

Cloud Storage

Cloud Storage is another way for keeping a backup of your files and refers to online space that you can use to store your data. Cloud storage is a model of data storage where the digital data is stored in logical pools, the physical storage spans multiple servers or locations, and the physical environment is typically owned and managed by a hosting company. Cloud storage can provide the benefits of greater accessibility and reliability in rapid deployment strong protection for data backup, archival and disaster recovery purposes and thus lower overall storage costs as a result of not having to purchase, manage and maintain expensive hardware. The data are said to be stored in the cloud when they are saved on a remote server, which is easily accessible from anywhere with internet access.

In most cases, public cloud storage can also be deployed much faster and with more scalability and accessibility than on-premises data storage. A form of cloud storage where the enterprise’s data and cloud storage resources both reside within the enterprise's data center and behind the firewall. Also known as internal storage clouds is a cloud storage services that are managed inside the data center and as a result almost always carry higher capital and maintenance costs than public cloud storage services due to the enterprise needing to provide the data center space, network connectivity, power and cooling. But, Private cloud storage does help resolve the potential for security and performance concerns while still offering many of the benefits of cloud storage such as scalability, reliability, rapid deployment and the option of management by a specialized cloud storage provider. This is mainly meant for big enterprises who have very large set of highly confidential data to be stored. Hybrid Cloud Storage A combination of public cloud storage and private cloud storage where some critical data resides in the enterprise's private cloud while other data is stored and accessible from a public cloud storage provider. With hybrid cloud storage, enterprises are able to mix and match cloud storage resources between local data center infrastructure and scalable, on-demand infrastructure, with the cloud storage provider typically fully managing the cloud storage. Hybrid cloud storage combines the advantages of scalability, reliability, rapid deployment and potential cost savings of public cloud storage with the security and full control of private cloud storage.

Cloud Database benefits · Elimination of physical infrastructure. In a cloud database environment, the cloud computing provider of servers, storage and other infrastructure is responsible for maintenance and availability. The organization that owns and operates the database is only responsible for supporting and maintaining the database software and its contents. In a DBaaS environment, the service provider is responsible for maintaining and operating the database software, leaving the DBaaS users responsible only for their own data.

· Cost savings. Through the elimination of a physical infrastructure owned and operated by an IT department, significant savings can be achieved from reduced capital expenditures, less staff, decreased electrical and HVAC operating costs, and a smaller amount of needed physical space.

How does a cloud database work

From a structural and design perspective, a cloud database is no different than one that operates on a business's own on-premises servers. Where an on premises database is connected to local users through a corporation's internal local area network, a cloud database resides on servers and storage furnished by a cloud provider, and it is accessed solely via the internet.

Accessed either through direct queries or via Application program interface calls, the database's behavior should be the same. However, it may be possible to discern small differences in response time. An on-premises database, accessed via a LAN, is likely to provide slightly faster response than a cloud-based database, which requires a round trip on the internet for each interaction with the database. In practice, however, the differences are likely to be small.
