What is Database-as-a-Service (DBaaS)?

Database-as-a-Service (DBaaS) is a managed cloud service model that lets users and companies easily access database services without worrying about managing software or infrastructure.

How does Database-as-a-Service work?

DBaaS providers host all your database infrastructure and data while enabling access through API endpoints. They follow best practices and operate all the databases, which means they take care of rapid provisioning, scalability, resiliency, failover, backup, and restoration.

In addition, DBaaS providers normally offer various features such as monitoring, alerts and notifications, round-the-clock support, and geo-replication for availability and backups. All maintenance and administrative tasks are handled by the service provider, freeing up users to benefit from using the database without the overhead of managing it.

What are the benefits of Database-as-a-Service?

DBaaS provides a zero-management and cost-effective solution that gives developers and companies faster, scalable deployments while reducing IT costs. The major benefits of DBaaS include:

Business agility

Business agility refers to the distinct qualities (such as adaptability, flexibility, balance) that allow organizations to respond rapidly to changes without losing momentum or vision. Cloud DBaaS applications are agile in nature, so they adapt seamlessly to any upgrades according to business or technology advancements. DBaaS allows rapid provisioning of database resources to provide new computing resources and storage facilities in the minimum possible time. Together, this adds agility and flexibility to development teams, no matter their size or industry.

The result is that developers and DevOps teams don’t have to bother with complex and time-consuming database provisioning and management, which can take anywhere from several hours to days to complete. Instead, they can focus on delivering on the business’ goals.

Enterprise-level security

Security is one of the most critical challenges in the DBaaS domain. As more and more enterprises host their data in the cloud, it’s crucial for DBaaS providers to prevent unauthorized access to data resources, disallow misuse of data stored on third-party platforms, and ensure data confidentiality, integrity, and availability.

DBaaS providers typically offer enterprise-level security that supports encryption and multiple layers of security to protect data at rest, in transit, and during processing. It also improves your data center security by adding strategic layers of protection that keep your data and systems safe. DBaaS providers offer SLAs that guarantee integrated access management and control of regulatory compliance standards. They also offer end-to-end network security with micro-segmentation and virtual private networks.

On-demand scalability

The DBaaS model provides automated and dynamic scaling. DBaaS providers adapt to workload changes and are able to manage load variations by increasing resources during peak hours without any service disruption, or by allocating fewer resources during periods of non-peak usage to help reduce costs. Users can quickly add storage and computing capacity to meet high processing demands while also defining usage threshold policies for how the system should behave during demand fluctuations.

High availability

In today’s fast-paced digital world, maintaining 24×7 operational uptime is a must for any modern business. Outages are directly proportional to the loss of revenue. As digital transformation becomes more and more essential, it’s increasingly important that your application service should remain up 24/7 without any downtime. If there’s any kind of system failure, the system should be intelligent enough to recover from the loss in no time.

The DBaaS model provides maximum high availability and runs at peak performance. It provides zero or no-data loss tolerance and eliminates a single point of failure. In case of any kind of failure in a single database instance, the platform automatically reroutes traffic to a replica/standby instance and maintains uptime. The model is intelligent enough to accept the database connections and allow enterprise developers to perform database queries even in the case of a system failure.

Is Database-as-a-Service a good fit for your business?

Not all Database-as-a-Service providers are the same. They differ significantly across a wide range of characteristics and capabilities. It’s important to select the right DBaaS provider for your organization, one that meets the technical requirements of your application workloads.
