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:

For the common 150 thread comparison, ScaleGrid averages almost 40% higher throughput over DigitalOcean for MySQL, with up to 46% higher throughput in write-intensive workloads.

Angular 11 SpringBoot CRUD MySQL Example

In the tutorial, I introduce how to create an “SpringBoot Angular 11 MySQL CRUD Example” with POST/GET/PUT/DELETE requests to SpringBoot RestAPIs.

– Design overview system by Architecture Diagram that includes: Angular Client, SpringBoot RestAPIs, and MySQL database.
– Implement Angular CRUD Client with Angular built-in HttpClient to communicate with server side.
– Implement SpringBoot RestAPIs that gets data from MySQL using Spring Data JPA and returns back data as Json format to requested Angular Client.

Overall Angular 11 SpringBoot MySQL CRUD Architecture Application

Overall Angular 11 SpringBoot MySQL CRUD Architecture Application

  • We build backend SpringBoot Application that provides RestAPIs for POST/GET/PUT/DELETE Customer entities and store them in MySQL/PostgreSQL database.
  • We implement Angular Application that use Angular HTTPClient to interact (call/receive requests) with SpringBoot backend and display corresponding page view in browser.

Overview SpringBoot CRUD MySQL Backend Architecture

Overview SpringBoot CRUD MySQL Backend Architecture

  • For building RestAPIs in SpringBoot application, we use Spring MVC Web.
  • For interacting with database MySQL/PostgreSQL, we use Spring JPA.
  • We implement RestAPI’s URL in RestAPIController.java file to process bussiness logic.
  • For manipulating database’s records, we define a JPA model for mapping field data and use a JPA CRUD repository to do CRUD operation with MySQL/PostgreSQL.

– SpringBoot Project Structure

SpringBoot Project Structure

  • models package defines Customer model and Message response class.
  • repository package defines Spring JPA repository class CustomerRepository to do CRUD operation with database.
  • service package defines a middleware class CustomerServices between Controller and Repository.
  • controller package defines a RestAPI Controller RestAPIController to handle POST/GET/PUT/DELETE request.

Overview Angular 11 CRUD Architecture Design

Overview Angular 11 CRUD Architecture Design

Angular 11 CRUD Application is designed with 3 main layers:

  • Service Layer is used to define Angular Common Services and HttpClient Services to interact with RestAPIs
  • Component Layer is used to define Angular Components to show views in Browser for interacting with Users
  • Router Layer is used to route URLs mapping with the corresponding Angular Components

Angular CRUD Application – Project Structure

Angular 11 CRUD Application defines 3 components, 2 services, 1 routers, and 2 data models:

– Components:

add-customer component is used to add a new customer to system
list-customer component is used to show all customers on view pages, delete a customer and update a customer
message component is used to define a view to show logging message on browser

– Services:

customer.service.ts defines POST/GET/PUT/DELETE HTTP requests to SpringBoot RestAPIs with the built-in Angular HttpClient.
message.service.ts defines an array storage to log all messages when Angular CRUD App running

– Router: app-routing.module.ts defines how to map a corresponding Angular component with an URL.

– Models:

customer.ts defines the main data model of our application.
message.ts defines the response data model between SpringBoot and Angular application.

Goal – Angular SpringBoot CRUD MySQL

– Add new Customer: from Angular to SpringBoot and save to MySQL.

– Add new Customer: from Angular to SpringBoot and save to MySQL.

– List All Customers: from Angular calls SpringBoot RestAPI to get customer from MySQL.

List All Customers: from Angular calls SpringBoot RestAPI to get customer from MySQL.

– Details a Customer: from Angular calls get http request from SpringBoot RestAPI to get a record in MySQL database

Details a Customer

– Update a Customer: from Angular calls a put http request from SpringBoot RestAPI to update a record in MySQL database.

– Update a Customer: from Angular calls a put http request from SpringBoot RestAPI to update a record in MySQL database.

– Delete a Customer: from Angular calls a delete http request from SpringBoot RestAPI to delete a record in MySQL database.

– Delete a Customer: from Angular calls a delete http request from SpringBoot RestAPI to delete a record in MySQL database.

– Check database records: do a get request from Angular to SpringBoot RestAPI.
