Cloud computing has spurred a lot of technological innovation. It’s now easier than ever to develop an app and host it, thanks to cloud computing providers such as Azure and Amazon Web Services (AWS). Before these services sprung up, developers needed to buy and maintain their own servers or sign long-term contracts with co-location providers, which doesn’t come cheap.
All cloud-based apps are powered by database software. These databases enable the apps to retrieve data when needed and show it to the user. There are endless databases developers can use for a cloud-based app, with each one having its pros and cons.
A cloud database is built and accessed via a cloud platform. It offers the same features as traditional database software but with the extra convenience and flexibility of cloud computing. It enables developers to host database software without buying expensive hardware. The software could be a relational database or a NoSQL database and is accessed via a web interface or API.
We tested different cloud database software to identify the best ones. We selected the best based on important factors including pricing, performance, features, customer support, ease of use, etc. These databases have their pros and cons but are the best you can choose from.

Best overall cloud database provider
Amazon Web Services (AWS) is the world’s biggest cloud provider, with a network of over 100 data centers globally. It offers many databases as part of its cloud service, including the Relational Database Service (RDS).
RDS is a database-as-a-service platform, and it's a good choice for developers and data scientists. You can build your database around your needs and control where your data is stored. This service supports different types of database formats including MySQL, SQL Server, MariaDB, and Amazon's native Aurora.
AWS offers a free tier for RDS that you can use to test its features. This free tier provides 750hrs of database services, 20GB of storage, and 20GB of data backups in one year. However, note that you'll need valid credit card details to sign up.
RDS is very secure and easy to scale, thanks to AWS’s unmatched physical server infrastructure. It’s easy to back up and retrieve your data when needed on RDS.
AWS operates on a pay-as-you-go model, meaning you only pay for the database resources you consume. But it’s a bit hard to estimate your final cost; AWS is known for being cost-effective for low-volume users but expensive for high-volume users.

FAQs
How to choose cloud database software
1. Cost
Cost is the primary consideration when choosing any platform. Ensure you pick a database software you can afford in the long term. Pricing for cloud databases isn’t usually standard; the final bill depends on how much data you store and retrieve in a given period. Hence, read the fine print to see if there are any hidden costs.
2. Scalability
Pick a database platform that scales easily. You should be able to add much more data without affecting the database’s performance. Some databases scale horizontally, meaning you can easily add more servers or nodes to the cluster to handle increasing data needs. Horizontal scaling is more economical than vertical scaling, which requires upgrading the hardware to boost capacity.
3. Customer support
Things can go wrong at any time, and you’ll need external help. You should be able to contact a human support representative to seek help when things go wrong; you can do this via live chat, telephone, or email. Your database provider should also offer complementary support resources such as FAQs, user guides, video tutorials, extensive documentation, etc.
Check user reviews to see if people speak well about the software’s customer support system.
Features of a cloud database
1. Encryption
Your database software should encrypt data in transit to prevent leaks or theft. This encryption is essential because you'll be uploading sensitive business and customer data to it. If the data is stolen, your reputation will take a hit, and you may be on the hook for significant financial damages.
2. Third-party integration
Your database software should have integrations with third-party tools. It should integrate well with the development framework you've chosen. For example, if you're using the Django framework, a MySQL or PostgreSQL database is a smart choice.
3. Flexibility
The main attraction of a cloud database is flexibility and convenience. You should be able to sign up on your chosen cloud provider and spin up the database easily. The database should be able to handle increasing storage needs without sacrificing performance and reliability.
4. Query engine
The database must have a system to query data from it. Data query is achieved via a programming language such as SQL. You can also use these languages to modify data on the database. Querying is similar to coding but with simpler codes and instructions.
More on cloud databases
Databases are just as an important part of cloud services as with normal IT operations. If you're using cloud management software or a cloud broker service then it's likely that you're drawing on multiple cloud platforms, which means it's important to be able to store your data in the type of database you need for queries.
Traditionally the most common form of database was a relational one, as used in Microsoft Access and it's more powerful big brother, MySQL. In these sort of databases there is a direct relationship between the different points of data, arrange in columns and rows.
However, these days non-relational databases have become more common, in which data is stored without explicit structure and mechanisms to link it. These have become more in demand for business intelligence tools and cloud analytics, which seek to connect underlying trends which might be otherwise hidden. This might be done by querying existing databases or even unstructured data found in data lakes.
Whichever types of database you need, most providers offer the choice of different database formats to use as required. Here we'll look at the best of them.
