Database-as-a-Service (DBaaS) is a cloud computing service that allows you to access your data anywhere. As a hosted/managed service, users do not need to worry about setting up hardware or installing software. All databases, including NoSQL, MySQL, and PostgreSQL, have database hosting choices. MongoDB Atlas is an example of a very scalable NoSQL DBaaS service.

Everything needed to run a database in the cloud is included in the DBaaS subscription, including database provisioning, licenses, support, and maintenance. Developers can leverage cloud-hosted APIs to create new apps by programmatically accessing and altering data. As a result, DBaaS and other SaaS subscription-based cloud products have a lot in common.

There is no additional cost as a managed service; you can go right to work extracting value from your data repository.

What’s the Difference Between DBaaS and Database Management?

Source: Information Age

Database maintenance in the cloud is frequently considerably easier than on-premises alternatives. The database administration tools are nearly comparable, allowing you to rapidly and easily provision databases on the hosted infrastructure.

Cloud computing concepts allow you to delegate time-consuming infrastructure management to a service provider, who is responsible for keeping the physical and application layers operational and optimal.

Outsourcing infrastructure administration frees you to focus on the data itself, reclaiming time and resources that would otherwise be spent on low-level maintenance activities, whether you are an individual developer or manage a team of data engineers and developers.

Benefits of DBaaS:-

  • No additional hardware is required on-site

As modern applications index, search and analyze a wide range of file types, including video, audio, and other unstructured formats, database sizes continue to rise tremendously. Constant investments in extra storage and processing capacity are required to accommodate expansion.

Without having to worry about hitting capacity or making upfront hardware investments, your database can continue to grow. DBaaS services are also fully managed, with infrastructure, hardware, operating systems, and software handled by providers (such as MongoDB). This frees up your time and the time of your developers/data analysts to focus on developing apps or extracting value from your Database, with no additional resources needed to operate and maintain the platform.

  • Database deployment is quick

Extending and upgrading data operations is much simplified when using the Database as a Service architecture.  

Developers can also quickly provision databases as needed, replicating datasets and configurations without the need for IT infrastructure help. APIs included in the cloud service allows them to build the next-generation applications that businesses need to fulfill their strategic goals.

Developers can deploy code updates and upgrades that streamline data-driven operations faster if they can complete these relatively easy administration duties quickly.

  • Data operations that are fit for the future

NoSQL database selection MongoDB Atlas, for example, is a DBaaS that enhances the capabilities of your big data operations. By constructing an operational data layer (ODL) on top of a NoSQL database, unstructured managed databases can be utilized to supply data as a service.

The ODL makes all of your company’s data available on-demand, allowing you to create game-changing new applications that help your company do more with its data. An ODL is a crucial step in the development of intelligent, rapid, real-time applications.

The pricing has not been provided yet by Amazon Neptune. 


  • You can easily analyze data using this software. 
  • It is compatible with the most often used consult language, has a high-security level, and works quickly, providing great performance to any database consult.


  • Whenever there is a poor connection, it leads to data loss. 
  • It is complex and expensive. 

Amazon DocumentDB

Amazon DocumentDB (with MongoDB compatibility) is a database service designed specifically for large-scale JSON data management, completely managed and connected with AWS, and enterprise-ready with excellent durability.

Amazon DocumentDB was built from the ground up to provide the scalability and durability that mission-critical MongoDB applications require. Storage increases automatically up to 64TiB in Amazon DocumentDB without affecting your application. Regardless of the quantity of your data, it enables millions of requests per second with up to 15 low latency read replicas in minutes, with no application downtime.

Key Features

  • MongoDB compatible
  • Fully managed
  • Performance at scale
  • Highly secure and compliant 
  • Highly available 


The pricing for Amazon DocumentDB is $0.10 GB/per month. However, the prices vary across AWS regions. 


  • It has amazing scalability. 
  • Provides great security and is compatible with MongoDB. 


  • It takes a lot of time before it is available. 
  • Costs a lot when the region varies. 

Amazon Athena

Amazon Athena is a web-based cloud storage application that enables data analysts to do interactive searches within Amazon Simple Storage Service (S3). Large-scale data sets are employed with Athena.

On Amazon Web Services, Amazon S3 is used for online backup and preservation of data and applications (AWS). With use cases like data storage, archiving, website hosting, data backup and recovery, and application hosting for deployment, Amazon S3 was intended to make web-scale computing easier for developers. Amazon Athena allows customers to utilize Structured Query Language to analyze data in Amazon S3 (SQL). The software is intended for ad hoc and sophisticated analysis.

Key Features

  • There is no server to maintain. The underlying infrastructure is not managed by analysts. Configuration and software updates are handled automatically by the software.
  • SQL querying is made simple. Presto, a distributed SQL query engine specialized for low-latency data analysis, is used by Athena.
  • Integrations. Athena interfaces with other Amazon services out of the box, including AWS Glue, making it easier to integrate with other services.
  • Query federation Athena can conduct SQL queries against relational, nonrelational, object, and custom data sources using Amazon Athena Federated Query.
  • Security. AWS Identity and Access Management (IAM) rules, Amazon S3 bucket policies, and access control lists are all used by Athena.


You just pay for the queries you run using Amazon Athena. Each query is paid based on the amount of data it scans. As each of these techniques reduces the amount of data, compressing, splitting, or changing your data to a columnar format can save you money and increase speed.


  • Athena performs fast queries on Amazon S3 data. It performs admirably.
  • Athena has a user-friendly interface that allows users to perform inquiries and trace their previous queries.
  • Works properly with Amazon Web Services Ability to visualize data quickly


  • The AWS Athena guide contains few samples, making it difficult to seek assistance from it.


Azure Cosmos DB has native support for NoSQL databases, numerous well-defined consistency models, single-digit millisecond latencies at the 99th percentile, and high availability with multi-homing capabilities and low latencies everywhere on the globe.
