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:

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:

Configure PMM2 For Azure MySQL Database With SSL

Registering AzureDB without SSL in PMM

If you are registering a normal MySQL database you will run the below command & it will be registered.

server=db-server.mysql.database.azure.com
monitoruser=monitor_mysql@db-server
monitorpwd=xxxxxxxx
server_name=MyProdDB1pmm-admin add mysql --username=$monitoruser --password=$monitorpwd --host=$server --service-name=$server_name --query-source=perfschema

SQLCopy

DB connectivity with SSL

As per the link provided below you can download the generic certificate to connect to the Azure database. Using that you can connect to MySQL even with verify_ca mode too.

Successful connection with SSL
mysql --user=$monitoruser --password=$monitorpwd --host=$serverUnsuccessful connection with verify ca SSLmysql --user=$monitoruser --password=$monitorpwd --host=$server --ssl-mode=VERIFY_CA
ERROR 2026 (HY000): SSL connection error: CA certificate is required if ssl-mode is VERIFY_CA or VERIFY_IDENTITYSuccessful connection with verify ca SSL
mysql --user=$monitoruser --password=$monitorpwd --host=$server --ssl-mode=VERIFY_CA --ssl-ca=azure-ca.crt

Error Registering SSL DB

For SSL you need to supply the parameter -tls, however, that also throws an error.

Generate new SSL

Based on the bug raised, I found that we need SSL client key & client certificate generated separately. I used the below command to generate new files. I have highlighted the one I used later.

MySQL on Azure Performance Benchmark – ScaleGrid vs. Azure Database

Microsoft Azure is one of the most popular cloud providers in the world, and a natural fit for database hosting on applications leveraging Microsoft across their infrastructure. MySQL is the number one open source database that’s commonly hosted through Azure instances. While Microsoft offers their own Azure Database product, there are other alternatives available that may be able to help you improve your MySQL performance. In this blog post, we compare Azure Database for MySQL vs. ScaleGrid MySQL on Azure so you can see which provider offers the best throughput and latency performance. We measure latency in ms 95th percentile latency.

Scalegrid achieves up to 4 times higher throughput and averages 64% lower latency across all number of threads compared to Azure Database for MySQL. Read now

MySQL Azure Performance Benchmark

In this benchmark report, we compare MySQL hosting on Azure at ScaleGrid vs. Azure Database for MySQL across these three workload scenarios:

  • Read-Intensive Workload: 80% reads and 20% writes
  • Balanced Workload: 50% reads and 50% writes
  • Write-Intensive Workload: 20% reads and 80% writes

We measure the MySQL throughput and latency performance, and measure throughput in terms of queries per second (QPS) and latency in terms of 95th percentile (ms). Check out our Benchmark Configuration section below the performance report to see how these tests were configured.

MySQL Read-Intensive Performance

MySQL read-intensive workloads are workloads that are typically dominated by read operations, such as SELECT. So, a read-intensive workload would be one that searches the database more often vs. writing to it. Percona has a great post on read-intensive vs. write-intensive workloads where you can learn more.

What Exactly Is Data Governance?

The first step is to understand what is data governance. Data Governance is an overloaded term and means different things to different people. It has been helpful to define Data Governance based on the outcomes it is supposed to deliver. In my case, Data Governance is any task required for:

  • Compliance: Data life cycle and usage is in accordance with laws and regulations.
  • Privacy: Protect data as per regulations and user expectations.
  • Security: Data & data infrastructure is adequately protected.

Why is Data Governance hard?

Compliance, Privacy, and Security are different approaches to ensure that data collectors and processors do not gain unregulated insights. It is hard to ensure that the right data governance framework is in place to meet this goal. An interesting example of an unexpected insight is the sequence of events leading to leakage of taxi cab tipping history of celebrities.
