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:

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.

Build Nodejs CRUD Application with MySQL/PostgreSQL - Express RestAPIs + Ajax

https://loizenai.com/build-nodejs-crud-application-with-mysql-postgresql-express-restapis-ajax-post-get-put-delete-request/

In the tutorial, I will introduce how to create a Fullstack Nodejs RestAPIs CRUD Application to MySQL/PostgreSQL database using Express framework and Sequelize ORM for building Backend and using Bootstrap, JQuery Ajax for building frontend client

We have 4 main blocks for the application:

Architecture

  • For building RestAPIs in Nodejs application, we use Express framework.
  • For interacting with database MySQL/PostgreSQL, we use Sequelize ORM.
  • We define APIs URL in router.js file
  • We implement how to process each API URL in controller.js file
  • We use Bootstrap and JQuery Ajax to implement frontend client.

Node JS Express CRUD Example with MySQL

In this tutorial, you will learn how to build crud (create, update, read, delete) application in node js express js framework with MySQL database.

Node js express crud tutorial MySQL will create a crude customer management application. In which you can add customers, edit customers and also delete customers from the database using node js express with MySQL database.

Node.js Express Sequelize MySQL CRUD RestAPIs Example

https://loizenai.com/nodejs-express-sequelize-mysql-restapis-example/

In the tutorial, I will introduce step by step how to create a ‘Node.js Express Sequelize MySQL CRUD RestAPIs Example’ with a full-stack technologies: Express RestAPI Framework (Cors + Body-Parse) + Sequelize ORM + MySQL.

Reactjs Nodejs MySQL CRUD Appliation

In the tutorial, I introduce how to build an “React.js Nodejs CRUD MySQL Example” project with the help of Ajax to POST/GET/PUT/DELETE requests with step by step coding examples:

– Nodejs project produces CRUD RestAPIs with MySQL database using the supporting of Sequelize ORM.
– React.js project will consume the Nodejs CRUD RestAPIs by Ajax then show up on Reactjs component’s views.

what will I do?

– I draw a fullstack overview Diagram Architecture from React.js Frontend to MySQL database through Nodejs RestAPI backend.
– Develop Nodejs CRUD RestAPIs with the supporting of Sequelize ORM.
– Implement Reactjs CRUD application with Ajax fetching APIs to do CRUD request (Post/Get/Put/Delete) to Nodejs Backend APIs.
– I create a testsuite with a number of integrative testcases with CRUD RestAPI requests from Reactjs to do CRUD requests to Nodejs RestAPIs Server and save/retrieve data to MySQL database.

Overall Architecture System: Reactjs + Nodejs + MySQL

Overall Architecture System: Reactjs + Nodejs + MySQL

  • We build a backend: Nodejs CRUD Application with MySQL that provides RestAPIs for POST/GET/PUT/DELETE data entities and store them in MySQL database.
  • We implement React.js CRUD Application that use Ajax to interact (call/receive requests) with Nodejs CRUD application and display corresponding data in Reactjs Component.

Nodejs MySQL CRUD Design Application

We have 4 main blocks for the application:

  • For building RestAPIs in Nodejs application, we use Express framework.
  • For interacting with database MySQL, we use Sequelize ORM.
  • We define APIs URL in router.js file
  • We implement how to process each API URL in controller.js file
  • We use Bootstrap and JQuery Ajax to implement frontend client.

Reactjs CRUD Application Design

Reactjs CRUD Application Design

– Reactjs CRUD Application is designed with 2 main layers:

React.js components let you split the UI into independent, reusable pieces, and think about each piece in isolation.
Ajax is used by Reactjs component to fetch (post/put/get/delete) data from remote restapi by http request
Reactjs CRUD Application defines 5 components:

  • Home.js is used serve as the landing page for your app.
  • AppNavbar.js is used to establish a common UI feature between components.
  • CustomerList.js is used to show all customers in the web-page
  • CustomerEdit.js is used to modify the existed customer
  • App.js uses React Router to navigate between components.

Integrative Project Goal
