Upgrading and modernizing your database can sound like an expensive proposition. But it doesn’t have to be. One major electronics company found that shifting from MySQL to CockroachDB saved them $700,000 in their first year, earning them a 149% ROI.
The company in question, a US-based electronics company that employs more than 10,000 people, initially sold electronic devices with any required software embedded on the device itself. But the Internet-of-Things age opened the door for innovation by allowing devices to connect to software via the web, bypassing the hardware and processing limitations of the devices themselves.
This, however, meant building a cloud-native IoT software and pairing it with a database that was capable of handling the workloads that would be generated by millions of internet-connected devices. Because the company operates globally, they also needed to build a system that would allow them to comply with region-specific regulatory requirements.
The company built their new IoT applications using a cloud-native microservices architecture, but quickly realized that getting MySQL — the RDBMS they had been using — to work as needed within this new distributed architecture was going to be expensive. Among other things, this would require:
While MySQL itself is free, the company recognized that the cost of this project in developer-hours was massive.
It also recognized that this would not be a one-time expenditure. All of this custom logic, and every instance of the database, would have to be regularly maintained and updated. Some of the work would need to be redone every time the company expanded and wanted to add a new shard or open a new region.
“I just get so excited about this technology. We would have so much downtime before, we don’t need to deal with that anymore.” — Principal Cloud Architect
Switching to CockroachDB Self-hosted allowed the company to immediately eliminate many of the expenses associated with scaling up and managing MySQL. CockroachDB is a cloud-native distributed SQL database that has been architected from the ground up for distributed transactional workloads, and it does a lot of the manual work that their MySQL system required automatically. Here are some of the benefits of CockroachDB:
“CockroachDB removes the need to write application code for how data relates to other data, for managing shards, for ensuring consistency, updating downstream systems, etc. We can move faster because CockroachDB handles things we used to have to address in the application layer.” — Senior Cloud Architect
The shift allowed the company to realize a lot of important goals for their application, including zero downtime for the database, since schema changes and updates didn’t require going offline.
Running CockroachDB themselves did mean that there were still operational costs and developer-hours required to maintain the database, though. They were running seven separate instances of CockroachDB, which made updates and testing a rather painstaking process. And as the company continued to grow and its data needs continued to expand, the costs of this maintenance were growing.
Initially, the company considered creating a database operations team to manage database maintenance and offer a kind of DBaaS internally using their CockroachDB deployments. However, this would have required hiring additional DBAs.
At the same time, CockroachDB’s managed service, CockroachDB Dedicated, became available. The company decided that, rather than expand its own team, it would switch to CockroachDB Dedicated and leave the management of its database to the experts.
The migration itself was no simple task (migrations never are). It took 10 person-months for coordination, performance testing, creating a new broker, micro integration, and setting up CI / CD tooling, monitoring, and alerting.
Ultimately, the migration cost the company an estimated $200,000, and the CockroachDB Dedicated license was more expensive, too. However, the company still ended up with a savings of $700,000 in year one. That’s a first-year ROI of 149% compared to operating CockroachDB Self-hosted:
|Self-hosted (with expansion)
|License / subscription
|Migration expenses (one time, year one)
|Difference (net benefit)
|ROI = (return - cost of investment) / cost of investment * 100
|// One-year ROI
And although there’s no way to be certain what sticking with MySQL would have cost the company — they never attempted to operate it at this scale — it’s likely that comparison would be even more stark. MySQL has no license cost, but as discussed above, it is significantly more complex to operate than CockroachDB Self-hosted, so the labor and operations costs would have been quite a bit higher.
Of course, CockroachDB Dedicated didn’t just save the company money — it also saved them time, particularly when compared with MySQL. Instead of bogging developers down with database operations tasks, the move to CockroachDB Dedicated meant those tasks were being handled by Cockroach Labs, enabling the company’s developers to focus on improving and adding new features to their own software.
Using CockroachDB Dedicated has also made it easier for the company to create and maintain staging and testing environments that directly mimic production, reducing the time and effort required to test new features after they’ve been developed.
“If we managed the database ourselves, our DevOps team would be potentially 3x bigger […] We want the people who built the database to manage the infrastructure while we keep full focus on customer experience.”
— Senior Cloud Architect
