Using cloud databases opens a whole new set of features for your applications. But, choosing the perfect cloud database solution for your requirements can be harder than you think.

So, in this article, I will discuss 5 cloud databases solutions for JavaScript with feature comparisons to help you choose the best one for your next project.

1. Cloud Firestore

Cloud Firestore is a NoSQL document database for client and server applications.

Like Firebase’s real-time database, Cloud Firestore uses real-time listeners to keep your data synchronized across client applications. You can directly use the database from your Browser using their JavaScript SDK.

Besides, it provides offline support for mobile and web applications and makes sure that applications run regardless of network latency or Internet connectivity.

Firebase is mostly suitable for applications where you need real-time communication.

Key features of Cloud Firestore:

• In real-time applications, Cloud Firestore synchronizes data between devices.
• Structures and queries data using collections and documents.
• Offline data access is possible thanks to a robust on-device database.
• Provides the service of serverless development.
• To help you get started quickly, SDKs directly interact with Firebase authentication.

You can get started with Cloud Firestore at no cost.

Cloud Firestore provides a free quota of 50000 reads, 20000 writes, and 20000 deleted per day as a free quota. If it is not enough, you can always upgrade your plan and pay based on your usage.

For example, 0.06 USD will be charged for 100000 document reads beyond the free quota. You can find a detailed description of the pricing modal in their documentation.

2. AWS DynamoDB

DynamoDB is one of the most popular NoSQL database services provided by AWS.

If you configure AWS Cognito Authentication with Fine-Grained Access Control, you can directly access DynamoDB from your browser using their JavaScript SDK.

In a nutshell, DynamoDB is a key-value or document-based database and can be recommended as the best solution when you need hyper-scalability and high availability than consistency.

Key features of DynamoDB:

• It is a highly available database with fully managed, multi-regional, and multi-master functions.
• It can handle more than trillions of requests per day and millions of requests per second at its peak.
• DynamoDB Accelerator provides an in-memory cache that is fully managed.
• It gives a single-digit millisecond response time at any scale because of its multi-region replications.
• DynamoDB adjusts tables automatically to compensate for capacity and maintains performance with no administration.

DynamoDB provides 25GB of free storage under its 12 months free tier plan.

Apart from the free tier, there are 2 pricing options you can choose from. The first one is the on-demand capacity plan, where you pay per request for the data reads and writes your application performs on your tables. The second one is theprovisioned concurrency plan, where you can specify the number of data reads and writes per second you require for your application.

3. Google Cloud SQL

Google Cloud SQL is a service provided by Google as part of its cloud platform.

Google Cloud Platform offers a fully managed service for relational databases like MySQL, PostgreSQL, and SQL Server. It ensures higher performance, availability, scalability, and convenience while also utilizing Google’s private global network for improved security.

Key features of Google Cloud SQL:

• The maintenance cost is relatively less compared to other services.
• Cloud SQL ensures business continuity which is data backup and recovery at any disaster.
• Cloud SQL ensures security and compliance by providing data encryption and firewall protection.
• You can set up your first Google database app in minutes using standard connection drivers and migration tools.
• Cloud SQL has built-in task management so you can focus on expanding your business while on the go.
• Google Cloud SQL provides a REST API for programmatically managing your instances.

The pricing modal of Google Cloud SQL is a bit complicated compared to AWS and Firebase. You can select a separate plan based on the instance type you use like MySQL, PostgreSQL, and SQL Server.

4. Azure Cosmos DB

Azure Cosmos DB is a fully managed, elastically scalable, and globally distributed NoSQL database service for modern applications.

It has numerous advantages, including the flexibility to employ document, key-value, wide-column, or graph-based data.

Key features of CosmosDB:

• The Azure database engine is schema-independent. As a result, no schema or index maintenance is necessary.
• Cosmos DB is the industry’s first and only service to provide full 99.99% high availability, 99th percentile read and write latency, guaranteed throughput, and consistency.
• Cassandra, MongoDB, Gremlin, and Azure Table Storage wire protocols are implemented directly in Cosmos DB.
• With the press of a button, we can add or remove any of the Azure regions from our Cosmos account at any moment.

Azure Cosmos DB is a good solution if you need a multi-model SQL database or a NoSQL database with an industry-standard API.

Similar to AWS DynamoDB, you can use Azure Cosmos DB free for 12 months. After that, you can continue with a preferred plan based on the time or usage.

5. Supabase

Supabase is a Firebase alternative that is both free and open-source!

You can build a backend with an API, authentication, storage, and a PostgreSQL database in minutes! You are missing out if you have never heard of Supabase.

Key features of Supabase:

• Creating and managing users is made easier with Supabase authentication.
• You can access the storage, store files, profile pictures, or anything else using the Supabase API.
• Each project in Supabase has its own PostgreSQL database, which allows you access to queries.
• Built-in security & monitoring.
• The Supabase Client makes it simple for developers to build secure and scalable products.
• A fantastic community of developers backs Supabase. Have a problem and need some assistance? Send a tweet, and you will receive the help you require.

Supabase has introduced 3 pricing plans as Free, Pro, and Pay as you go. Pro plan costs only $25 per project each month and includes everything you’ll ever need!

Conclusion

As you may have understood by now, each cloud database solution has its own set of strengths. The below figure shows a comparison of those 5 cloud databases discussed in terms of pricing, database type, etc.

However, the final decision should be made based on your project's requirements. You should consider about scalability, speed, availability, and pricing of each of these solutions and pick the best matching one for you.
