What is a database as a service?
For comparison, the DBaaS model is a paid subscription service where the database is implemented in the physical infrastructure of the service provider. Different levels of service are usually available. In the classic DBaaS order, the provider maintains a physical infrastructure and database, allowing the client to manage the content and run the database.
Instead, the client can set up a managed hosting agreement, where the provider manages the database. This latter option may be particularly attractive for small businesses that need a database, but do not have sufficient technical knowledge.
The benefits of a database in the cloud
Compared to the operation of a traditional database on a physical server on the site and a storage structure, the cloud database offers the following advantages:
Eliminate physical infrastructure.
In a cloud database environment, the cloud service provider for servers, storage, and other infrastructure is responsible for service and availability. An organization that owns and manages the database is solely responsible for supporting and maintaining the database program and its contents. In a DBaaS environment, the service provider is responsible for maintaining and running the database program, leaving DBaaS users responsible only for their own data.
By eliminating the physical infrastructure that the IT department owns and manages, significant savings can be made by reducing capital costs, reducing staff, reducing electricity and air conditioning costs, and reducing the necessary physical space.
Advantages of DBaaS
In addition to the advantages of using the database environment model in the cloud, contracting with DBaaS provides additional benefits:
If you require large database capacity due to seasonal peak loads or an unexpected increase in demand, the DBaaS provider can quickly provide additional capacity based on price, performance, and throughput through your infrastructure. The database operating in the traditional infrastructure of the site must wait for weeks or months of additional server resources, storage or communications.
In accordance with a service level agreement (SLA), a DBaaS provider may need to provide guarantees, which usually determine the minimum amount of available time and the transaction response time. SLA determines monetary and legal decisions if these thresholds are not reached.
In an IT environment for companies, with the exception of large multinational companies, it can be difficult to find global experts in a database, and storing them may be prohibitively expensive. In a DBaaS environment, a provider can serve thousands of customers, so finding, delivering and maintaining world-class talent is a small task.
To maintain their competitive advantage, DBaaS providers make every effort to ensure that all database software, server operating systems, and other aspects of the infrastructure are generally updated with security updates and features provided by service providers who regularly broadcast.
In order for the database service provider to comply with performance and availability guarantees, it must ensure continuous operation in the event of a primary data center failure for any reason. Assembly support usually includes the work of several data warehouses and servers of mirror images. If the failure is handled correctly, the failure in the backup data center should not be obvious to any client of this service.
Due to advances in technology and a highly competitive market among key service providers, prices depend on a wide range of cloud computing services for continuous calibration. Low prices are an important factor in the migration of local databases and other IT infrastructure to the cloud.
