Best MySQL DigitalOcean Performance – ScaleGrid vs. DigitalOcean Managed Databases
HTML to Markdown
MySQL is the all-time number one open source database in the world, and a staple in RDBMS space. DigitalOcean is quickly building its reputation as the developers cloud by providing an affordable, flexible and easy to use cloud platform for developers to work with. MySQL on DigitalOcean is a natural fit, but what’s the best way to deploy your cloud database? In this post, we are going to compare the top two providers, DigitalOcean Managed Databases for MySQL vs. ScaleGrid MySQL hosting on DigitalOcean.
At a glance – TLDR
ScaleGrid Blog - At a glance overview - 1st pointCompare Throughput
ScaleGrid averages almost 40% higher throughput over DigitalOcean for MySQL, with up to 46% higher throughput in write-intensive workloads. Read now
ScaleGrid Blog - At a glance overview - 2nd pointCompare Latency
On average, ScaleGrid achieves almost 30% lower latency over DigitalOcean for the same deployment configurations. Read now
ScaleGrid Blog - At a glance overview - 3rd pointCompare Pricing
ScaleGrid provides 30% more storage on average vs. DigitalOcean for MySQL at the same affordable price. Read now
MySQL DigitalOcean Performance Benchmark
In this benchmark, we compare equivalent plan sizes between ScaleGrid MySQL on DigitalOcean and DigitalOcean Managed Databases for MySQL. We are going to use a common, popular plan size using the below configurations for this performance benchmark:
Comparison Overview
ScaleGridDigitalOceanInstance TypeMedium: 4 vCPUsMedium: 4 vCPUsMySQL Version8.0.208.0.20RAM8GB8GBSSD140GB115GBDeployment TypeStandaloneStandaloneRegionSF03SF03SupportIncludedBusiness-level support included with account sizes over $500/monthMonthly Price$120$120
As you can see above, ScaleGrid and DigitalOcean offer the same plan configurations across this plan size, apart from SSD where ScaleGrid provides over 20% more storage for the same price.
To ensure the most accurate results in our performance tests, we run the benchmark four times for each comparison to find the average performance across throughput and latency over read-intensive workloads, balanced workloads, and write-intensive workloads.
Throughput
In this benchmark, we measure MySQL throughput in terms of queries per second (QPS) to measure our query efficiency. To quickly summarize the results, we display read-intensive, write-intensive and balanced workload averages below for 150 threads for ScaleGrid vs. DigitalOcean MySQL:

Kotlin – Spring Security JDBC Authentication – SpringBoot + MySQL + Bootstrap
In the tutorial, JavaSampleApproach will show you how to create a Kotlin Spring Security JDBC Authentication with SpringBoot + MySQL + Bootstrap.
I. Technologies
– Kotlin 1.2.20 – Apache Maven 3.5.2 – Spring Tool Suite – Version 3.9.0.RELEASE – Spring Boot – 1.5.10.RELEASE – Bootstrap - MySQLII. Goal
We create a Kotlin MVC Web Application as below:
With 5 urls:
– ‘/’: access with everyone.
– ‘/user’: must authenticate and be accessed with user ROLE {USER, ADMIN}
– ‘/admin’: accessed by user with role Admin
– ‘/login’: login page
– ‘/403’: HTTP Error 403 Forbidden
We create 2 MySQL tables for 2 users (username/password):
- jack/jack has 2 roles {USER, ADMIN}
- peter/peter has 1 role USER
-> jack/jack can access both pages {user.html, admin.html}. While peter/peter just accesses 1 page user.html.
III. Implementation
– Create Kotlin Spring Boot project – Create Controller – Create View Pages – Configure Database – Configure WebSecurity1. Create Kotlin Spring Boot project
