Advantages of Cloud Databases Over On-Premise Databases.

April 19, 2022

The cloud has revolutionized the way businesses operate.

The cloud has allowed organizations to store their data in remote locations securely.

Slowly, many businesses moved away from on-premise databases, which have several disadvantages compared to cloud databases.

This blog post will discuss the advantages of using a cloud database and why so many organizations are making the switch!

The advantages of using a cloud database are:

Security: Cloud databases are more secure than on-premise databases.

Security is the primary concern in any system. Especially with more data-related regulations like GDPR, and the rising threats of data breaches, organizations are looking for more secure solutions to store their data.

Cloud databases offer robust security features like encryption and user authentication, making them more secure than on-premise databases. For instance, Snowflake ensures everything stored in their cloud is encrypted with AES-256 encryption.

They also offer additional security options like MFA and OAuth. To access the database, you must have a valid token or should go through an extra challenge.

Also, some cloud providers have teams of security experts who monitor the systems 24/365 to prevent any potential threats.

Lastly, you never have to worry about physical security like you would with an on-premise database with a cloud database. This includes fire, floods, or theft.

Scalability: Cloud databases can scale up or down as needed.

How fast a company and its data could grow is vastly unpredictable.

An on-premise database would require purchasing new hardware, which can be expensive.

With a cloud database, you only pay for what you use. You can quickly scale up or down your usage as needed without any upfront costs. For example, if you have sudden spikes in traffic, you can quickly scale up your resources to accommodate the load.

Using a cloud database only takes a few minutes to spin up a new instance. We can automate even them. Also, you don't have to hire professionals to attach them to the existing system physically.

Flexibility: Cloud databases are more flexible than on-premise databases.

A cloud database gives you the flexibility to choose from various database engines that best fit your needs.

For example, AWS offers several different relational database options—Amazon Redshift, Postgres, MySQL, MariaDB, Oracle, and Microsoft SQL Server.

Not to mention, you're not limited to one database engine. You can use multiple database engines for different applications or workloads.

This flexibility also extends to the way you access and manipulate your data. With a cloud database, you can use APIs, web-based consoles, or command-line interfaces to access your data.

While achieving such flexibility isn't impossible in on-premise databases, it's more challenging and expensive. You only have a thin margin to experiment with.

High Availability: Cloud databases are highly available.

This means that your data is always accessible and won't be lost if there's an unexpected outage.

Cloud providers have multiple servers in different geographical locations. So, if one server goes down, the others can pick up the slack. This ensures that your data is always available when you need it.

If the server goes down in on-premise databases, you lose access to your data until the server is up and running again.

It is also possible to get on an SLA with the cloud provider to ensure availability. For instance, SLA for Azure Databricks indicates that it's available 99.95% of the time.

Cost: Cloud databases are more cost-effective than on-premise databases.

The upfront costs of an on-premise database can be expensive. You have to factor in the price of hardware, software, licenses, and maintenance.

With a cloud database, you only pay for what you use. There are no upfront costs or long-term commitments. You can also take advantage of discounts like reserved instances and volume pricing.

For example, AWS offers a Reserved Instance Discount which can save you up to 75% off the on-demand price.

In addition, many cloud providers also give you great free-tier options. For instance, AWS gives you 750 hours free with a 20G of general-purpose storage.

Lastly, the pay-as-you-go pricing model of a cloud database can help you save money in the long run.


There are several advantages of using a cloud database over an on-premise database. Cloud databases are more scalable, flexible, and cost-effective. They also provide high availability and disaster recovery.

If you're looking for a reliable database solution, then a cloud database is the way to go.
