Maintaining a database is a critical yet complex challenge for companies among various industries. Healthcare, retail, banking, tech companies and others all share the same untrivial task of selecting proper hardware, installing and configuring database software and further maintaining and administrating it. All of this requires significant investment and skilled IT staff to make sure everything is running smoothly and takes a considerable amount of time.
That’s where Database as a Service (DBaaS) comes into play allowing companies to get rid of all the pain associated with database deployment, configuration, and administration.
What is DBaaS?
Database as a Service (DBaaS) is a managed cloud service that provides users with access to databases without having to do actual database deployment and configuration. DBaaS means that the service provider takes care of all the heavy lifting: deployment, configuration, fine-tuning, as well as further administration, maintenance and scaling.
What is DBaaS used for?
There are multiple use cases for database service, and we have already briefly mentioned the industries where this is a must. But let’s focus on typical usage scenarios.
- Application development and testing – DBaaS provides developers with fast database provisioning, reducing the time previously spent on the deployment and configuration.

How Does DBaaS Work?
The database runs on cloud infrastructure managed by the provider. You interact with it via a web UI or API. The provider handles updates, backups, uptime monitoring, and performance optimization, reducing the need for in-house database expertise.
Categories of DBaaS
When talking about DBaaS, it is important to mention that there are several categories or types of DBaaS providers. Here, we focus on two main categories.
Public cloud providers
Cloud vendors like AWS (Amazon RDS, DynamoDB, Aurora), Google Cloud (Cloud SQL, Firestore), and Microsoft Azure (SQL Database, Cosmos DB) offer DBaaS directly within their ecosystems. This works well if you’re already using their services.
Proprietary cloud vendors
On the other hand, vendors like MongoDB Atlas, Snowflake, PlanetScale, Neon, and Firebolt offer proprietary cloud platforms. In these cases, users pay for both database usage and the underlying cloud services. While the database and infrastructure are provided by the vendor, the actual servers and storage are typically hosted on a public cloud as part of the vendor’s service agreement.
So what are the pros and cons of each type? We’ll try to summarize these below.
| Public cloud providers | Proprietary cloud vendors | |
|---|---|---|
| Pros | Unified billing and deployment through existing cloud accounts | Unified billing and deployment through a single vendor |
| Multiple cloud providers to choose from | Multiple cloud providers to choose from | |
| Integration with other services provided by the same public cloud | Often optimized for analytics or specialized use cases | |
| Cons | Vendor lock-in | Vendor lock-in |
| Must use a single cloud | Server costs are negotiated by the vendor and may be marked up when sold to you | |
| Harder to move workloads across hybrid or multi-cloud setups | Often built for cloud-only |
Advantages of DBaaS
So why are some companies moving to DBaaS instead of hosting database servers on-premises? While we’ve touched on the general benefits, here’s a focused list of the key advantages that make DBaaS so compelling:
- Reduced TCO (Total Cost of Ownership). DBaaS eliminates large upfront capital expenses in hardware and software, which are common with on-premises database setups. Instead, it offers a subscription-based model that turns these expenses into operational costs and along with minimized expense on a dedicated IT team, reduces TCO.
- Flexible scaling. DBaaS providers offer flexible infrastructure that can scale up or down easily according to current business demands. This flexibility ensures that database capacity corresponds to real-time business needs, resulting in const-efficiency along with minimized manual intervention.
- High Availability. DBaaS is a reliable solution when it comes to ensuring your database availability and accessibility. Cloud providers with DBaaS offerings include high availability features to ensure that databases remain accessible (sometimes with minimal downtime) even during unexpected outages.
- Enhanced Security. DBaaS providers typically make significant investments in security, using strong protocols to protect data both at rest and in transit. They also commonly adhere to industry regulations, helping businesses more easily meet compliance requirements.
- Simplified database management. With DBaaS, the cloud provider handles daily maintenance tasks such as updates, backups, and security patches, allowing the company’s IT teams to focus on more important work. This managed service model not only reduces administrative overhead but also ensures that databases consistently run on the latest, most secure software versions.
- Rapid provisioning. DBaaS enables developers to provision and configure databases quickly, speeding up the development process. Such rapid deployment and configuration allow rolling out new applications faster, providing businesses with a competitive advantage.
Disadvantages of DBaaS
While there are multiple advantages to DBaaS, there are several disadvantages to this approach as well. Here, we’ll summarize the most crucial disadvantages behind DBaaS.
- Lack of cost transparency. While indeed CAPEX is lower compared to traditional on-premises database deployments, DBaaS may lack transparency when it comes to pricing. As with other cloud services, there are often hidden costs that are hard to account for and that can be workload-specific, resulting in high operational expenses.
- Limited Control. With managed databases, an organization’s IT staff usually has limited access to underlying server features, as these are abstracted by the provider. Instead, users depend on the cloud provider to effectively manage the infrastructure.
- Network dependency. The benefits of DBaaS, especially when it comes to handling large data amounts and low latency, depend on the network. If an organization has a weak internet connection or experiences outages, it will lose access to its database until connectivity is restored. Additionally, slow internet speeds can lead to delayed query response times.
- Security Concerns. While public cloud security is generally considered robust, it is ultimately the vendor who manages the security of the database platform and underlying infrastructure. It is a matter of trust and competence resulting in some companies preferring direct control over the database and IT infrastructure security.
What to look for in a DBaaS?
It’s very important to understand what to pay attention to when selecting a DBaaS provider. And in this case, cost is just one of the factors. Here’s a summary of the most important considerations:
DBaaS deployment options
Some DBaaS providers require committing to a specific storage location within a single cloud. This limits the ability to move between clouds or take advantage of more cost-effective cloud options as they appear. Additionally, certain providers may not support on-premises analytics or deployment in Kubernetes environments. It’s important to carefully evaluate and exclude vendors that cannot meet all of your deployment and flexibility requirements.
Licensing flexibility
Consider if the selected database solution offers a license that allows transitioning between multiple clouds or on-premises environments. Understand the costs associated with maintaining different environments such as development, testing, backup, and production. Carefully examine pricing and research the hidden costs to avoid overpaying.
Ease of exiting
It would be great if a selected service provider were a perfect match for life. Sadly, that’s not always the case. To minimize the risk of vendor lock-in, research whether their APIs, database engines, or automation tools are proprietary or based on industry standards. Will migrating require you to refactor your code? It’s also essential to understand whether there are exit fees and how easily data can be migrated from their platform.
Ability to optimize
When selecting DBaaS, pay attention if it operates in a limited compute package only since database workloads are not the same. Database solutions that rely solely on node-based scaling (simply adding generic nodes as demand increases) may prevent you from optimizing both cost and performance. Look for platforms that support specialized nodes and offer tools to fine-tune slow queries, as these capabilities are essential for controlling cloud costs while maximizing efficiency.
Depth of analytics
Consider if DBaaS can support more than just basic descriptive analytics. Some workloads demand specialized analytics, such as geospatial or time-series processing, while predictive analytics is becoming essential for data science teams. It’s important to choose a solution that can support a broad range of analytical use cases and scale to meet the needs of diverse teams as your cloud database becomes more widely adopted within your organization.
How to choose the best DBaaS solution?
Selecting the right Database as a Service solution is essential for organizations looking to enhance database management while ensuring scalability, reliability, and high performance. Making the best choice requires careful evaluation of key factors such as database types, scalability, security, performance, and vendor support.
Here are some of the most important factors to consider when choosing a DBaaS provider:
- Define requirements. Estimate the amount of data you have, performance needs, and specific database requirements. Understanding these basics will help you filter DBaaS providers that do not match your business needs.
- Evaluate service offerings. Investigate the types of databases offered (relational vs. NoSQL), how easy they are to scale, backup, and what security features they provide. Choose a DBaaS that meets your technical and operational requirements.
- Reliability and performance. Take into account DBaaS provider’s infrastructure reliability, availability guarantees, and performance history. Go for providers with a strong record of minimal downtime.
- Security and compliance. Ensure the Database as a Service offers critical security features, such as data encryption and access controls. Make sure it complies with industry-standard regulations like GDPR and HIPAA.
- Support and SLAs. Learn the support services and Service Level Agreements (SLAs) guaranteed by a provider to make sure they meet your needs when it comes to issue resolution.
- Reviews and customer feedback. Research the feedback from existing customers about their experiences with the DBaaS provider. Customer reviews on platforms like G2 Crowd, TrustRadius, and Capterra can provide insights into the provider’s reliability and customer service quality.

What’s the difference between DBaaS and PaaS?
While both DBaaS and PaaS aim to simplify cloud computing, they serve different purposes. Key difference is that Platform as a Service provides exactly an infrastructure platform on which you can run a database along with other applications. Unlike Database as a Service, PaaS does not provide a “ready database”, so all the deployment, configuration and maintenance become your burden. However, PaaS is usually less expensive than DBaaS and offers more flexibility and can be used for various types of workloads.
What’s the difference between a DBaaS and a database management system?
Unlike DBaaS, which is essentially a cloud service, Database Management System (DBMS) is software that is usually installed and operated on (although not limited to) local servers or systems. In this case, DBMS is your responsibility. Your IT team is responsible for managing and maintaining the infrastructure on which the database system is running and the database maintenance itself. The same goes for database system sizing and scaling. However, with DBMS, you have greater control and flexibility over the database system, including custom configurations, software versions, and infrastructure choices.
Conclusion
DBaaS provides extreme simplicity and flexibility for companies when it comes to database deployment, configuration and maintenance since all of this is done by a database service provider. It can be a great fit for companies with small IT teams and limited budgets that want to avoid the complexities of managing on-premises databases.
However, it’s crucial to carefully assess your specific needs and thoroughly evaluate DBaaS offerings based on availability, performance, security, and support. Like any cloud service, choosing the right provider and plan is essential to avoid unexpected costs and ensure your business can grow confidently and efficiently.
Making an informed decision about DBaaS will empower your organization to leverage modern database capabilities while keeping control over budget and operational risk.
