      Video: Thank You Essential Data Center Workers

      Colocation, cloud and network services are at the heart of keeping us connected and the economy moving during the COVID-19 pandemic. To sustain peak performance, these services rely on the tireless and difficult work undertaken by frontline data center engineers and technicians.

      In the video below, INAP leadership shines the spotlight on our 100-plus essential data center workers, whose terrific performance enables our thousands of global customers to successfully operate their businesses through a period of immense challenge.

      Please join us in thanking them!


      At the outset of the pandemic, world governments classified certain sectors of the workforce as “essential” to the functioning of society. Along with healthcare, food service and transportation workers, data center employees were a fixture of these lists.

      Due to the behind-the-scene nature of their jobs, however, the world’s data center professionals are arguably the unsung heroes of the COVID-19 crisis. From e-learning and online gaming to telemedicine and work-from-home video conferencing, life would grind to a halt if not for data center operations teams.

      The pandemic necessitates these employees operate through less than ideal scenarios. On top of managing unprecedented surges in network demand, INAP’s data center operations team is navigating new policies and procedures implemented for their health and safety. This includes a “no access” that restricts colocation customers and non-essential vendors and contractors from entering our facilities. For a subset of our colocation customers, one result of this particular restriction has been an uptick in remote hands requests, wherein INAP technicians perform mission-critical maintenance to server and network hardware that’s normally the responsibility of the customer. It’s highlighted to our customers just how skilled our teams are at managing complex systems.

      Across the board, the team’s performance has not wavered during the pandemic. In many cases, it’s exceeded expectations.

      Our Los Angeles team, for instance, is staying on schedule with the first phase of a 1.8 MW expansion at our flagship facility in Redondo Beach, working carefully with contractors and utility companies all the while maintaining a live Tier 3 facility.

      The team’s attitude sacrifice and performance each and every one of our employees has made during the pandemic remind us how essential they are year-round, not just in times of crisis. None of us could do what we do without them.

      How To Use the MySQL BLOB Data Type to Store Images with PHP on Ubuntu 18.04

      The author selected Girls Who Code to receive a donation as part of the Write for DOnations program.


      A Binary Large Object (BLOB) is a MySQL data type that can store binary data such as images, multimedia, and PDF files.

      When creating applications that require a tightly-coupled database where images should be in sync with related data (for example, an employee portal, a student database, or a financial application), you might find it convenient to store images such as students’ passport photos and signatures in a MySQL database alongside other related information.

      This is where the MySQL BLOB data type comes in. This programming approach eliminates the need for creating a separate file system for storing images. The scheme also centralizes the database, making it more portable and secure because the data is isolated from the file system. Creating backups is also more seamless since you can create a single MySQL dump file that contains all your data.

      Retrieving data is faster, and when creating records you can be sure that data validation rules and referential integrity are maintained especially when using MySQL transactions.

      In this tutorial, you will use the MySQL BLOB data type to store images with PHP on Ubuntu 18.04.


      To follow along with this guide, you will need the following:

      Step 1 — Creating a Database

      You’ll start off by creating a sample database for your project. To do this, SSH in to your server and then run the following command to log in to your MySQL server as root:

      Enter the root password of your MySQL database and hit ENTER to continue.

      Then, run the following command to create a database. In this tutorial we’ll name it test_company:

      • CREATE DATABASE test_company;

      Once the database is created, you will see the following output:


      Query OK, 1 row affected (0.01 sec)

      Next, create a test_user account on the MySQL server and remember to replace PASSWORD with a strong password:

      • CREATE USER 'test_user'@'localhost' IDENTIFIED BY 'PASSWORD';

      You’ll see the following output:


      Query OK, 0 rows affected (0.01 sec)

      To grant test_user full privileges on the test_company database, run:

      • GRANT ALL PRIVILEGES ON test_company.* TO 'test_user'@'localhost';

      Make sure you get the following output:


      Query OK, 0 rows affected (0.01 sec)

      Finally, flush the privileges table in order for MySQL to reload the permissions:

      Ensure you see the following output:


      Query OK, 0 rows affected (0.01 sec)

      Now that the test_company database and test_user are ready, you’ll move on to creating a products table for storing sample products. You’ll use this table later to insert and retrieve records to demonstrate how MySQL BLOB works.

      Log out from the MySQL server:

      Then, log back in again with the credentials of the test_user that you created:

      When prompted, enter the password for the test_user and hit ENTER to continue. Next, switch to the test_company database by typing the following:

      Once the test_company database is selected, MySQL will display:


      Database changed

      Next, create a products table by running:

      • CREATE TABLE `products` (product_id BIGINT PRIMARY KEY AUTO_INCREMENT, product_name VARCHAR(50), price DOUBLE, product_image BLOB) ENGINE = InnoDB;

      This command creates a table named products. The table has four columns:

      • product_id: This column uses a BIGINT data type in order to accommodate a large list of products up to a maximum of 2⁶³-1 items. You’ve marked the column as PRIMARY KEY to uniquely identify products. In order for MySQL to handle the generation of new identifiers for inserted columns, you have used the keyword AUTO_INCREMENT.

      • product_name: This column holds the names of the products. You’ve used the VARCHAR data type since this field will generally handle alphanumerics up to a maximum of 50 characters—the limit of 50 is just a hypothetical value used for the purpose of this tutorial.

      • price: For demonstration purposes, your products table contains the price column to store the retail price of products. Since some products may have floating values (for example, 23.69, 45.36, 102.99), you’ve used the DOUBLE data type.

      • product_image: This column uses a BLOB data type to store the actual binary data of the products’ images.

      You’ve used the InnoDB storage ENGINE for the table to support a wide range of features including MySQL transactions. After executing this for creating the products table, you’ll see the following output:


      Query OK, 0 rows affected (0.03 sec)

      Log out from your MySQL server:

      You will get the following output



      The products table is now ready to store some records including products’ images and you’ll populate it with some products in the next step.

      Step 2 — Creating PHP Scripts for Connecting and Populating the Database

      In this step, you’ll create a PHP script that will connect to the MySQL database that you created in Step 1. The script will prepare three sample products and insert them into the products table.

      To create the PHP code, open a new file with your text editor:

      • sudo nano /var/www/html/config.php

      Then, enter the following information into the file and replace PASSWORD with the test_user password that you created in Step 1:


      define('DB_NAME', 'test_company');
      define('DB_USER', 'test_user');
      define('DB_PASSWORD', 'PASSWORD');
      define('DB_HOST', 'localhost');
      $pdo = new PDO("mysql:host=" . DB_HOST . "; dbname=" . DB_NAME, DB_USER, DB_PASSWORD);
      $pdo->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);
      $pdo->setAttribute(PDO::ATTR_EMULATE_PREPARES, false);

      Save and close the file.

      In this file, you’ve used four PHP constants to connect to the MySQL database that you created in Step 1:

      • DB_NAME : This constant holds the name of the test_company database.

      • DB_USER : This variable holds the test_user username.

      • DB_PASSWORD : This constant stores the MySQL PASSWORD of the test_user account.

      • DB_HOST: This represents the server where the database resides. In this case, you are using the localhost server.

      The following line in your file initiates a PHP Data Object (PDO) and connects to the MySQL database:

      $pdo = new PDO("mysql:host=" . DB_HOST . "; dbname=" . DB_NAME, DB_USER, DB_PASSWORD);

      Toward the end of the file, you’ve set a couple of PDO attributes:

      • ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION: This attribute instructs PDO to throw an exception that can be logged for debugging purposes.
      • ATTR_EMULATE_PREPARES, false: This option increases security by telling the MySQL database engine to do the prepare instead of PDO.

      You’ll include the /var/www/html/config.php file in two PHP scripts that you will create next for inserting and retrieving records respectively.

      First, create the /var/www/html/insert_products.php PHP script for inserting records to the products table:

      • sudo nano /var/www/html/insert_products.php

      Then, add the following information into the /var/www/html/insert_products.php file:


      require_once 'config.php';
      $products = [];
      $products[] = [
                    'product_name' => 'VIRTUAL SERVERS',
                    'price' => 5,
                    'product_image' => file_get_contents("")
      $products[] = [
                    'product_name' => 'MANAGED KUBERNETES',
                    'price' => 30,
                    'product_image' => file_get_contents("")
      $products[] = [
                    'product_name' => 'MySQL DATABASES',
                    'price' => 15,
                    'product_image' => file_get_contents("" )
      $sql = "INSERT INTO products(product_name, price, product_image) VALUES (:product_name, :price, :product_image)";
      foreach ($products as $product) {
          $stmt = $pdo->prepare($sql);
      echo "Records inserted successfully";

      Save and close the file.

      In the file, you’ve included the config.php file at the top. This is the first file you created for defining the database variables and connecting to the database. The file also initiates a PDO object and stores it in a $pdo variable.

      Next, you’ve created an array of the products’ data to be inserted into the database. Apart from the product_name and price, which are prepared as strings and numeric values respectively, the script uses PHP’s in-built file_get_contents function to read images from an external source and pass them as strings to the product_image column.

      Next, you have prepared an SQL statement and used the PHP foreach{...} statement to insert each product into the database.

      To execute the /var/www/html/insert_products.php file, run it in your browser window using the following URL. Remember to replace your-server-IP with the public IP address of your server:


      After executing the file, you’ll see a success message in your browser confirming records were inserted into the database.

      A success message showing that records were inserted to database

      You have successfully inserted three records containing product images into the products table. In the next step, you’ll create a PHP script for retrieving these records and displaying them in your browser.

      Step 3 — Displaying Products’ Information From the MySQL Database

      With the products’ information and images in the database, you’re now going to code another PHP script that queries and displays the products’ information in an HTML table on your browser.

      To create the file, type the following:

      • sudo nano /var/www/html/display_products.php

      Then, enter the following information into the file:


        <title>Using BLOB and MySQL</title>
        require_once 'config.php';
        $sql = "SELECT * FROM products";
        $stmt = $pdo->prepare($sql);
        <table border = '1' align = 'center'> <caption>Products Database</caption>
            <th>Product Id</th>
            <th>Product Name</th>
            <th>Product Image</th>
        while ($row = $stmt->fetch(PDO::FETCH_ASSOC)) {
            echo '<tr>';
            echo '<td>' . $row['product_id'] . '</td>';
            echo '<td>' . $row['product_name'] . '</td>';
            echo '<td>' . $row['price'] . '</td>';
            echo '<td>' .
            '<img src = "data:image/png;base64,' . base64_encode($row['product_image']) . '" width = "50px" height = "50px"/>'
            . '</td>';
            echo '</tr>';

      Save the changes to the file and close it.

      Here you’ve again included the config.php file in order to connect to the database. Then, you have prepared and executed an SQL statement using PDO to retrieve all items from the products table using the SELECT * FROM products command.

      Next, you have created an HTML table and populated it with the products’ data using the PHP while() {...} statement. The line $row = $stmt->fetch(PDO::FETCH_ASSOC) queries the database and stores the result in the $row variable as a multi-dimensional array, which you have then displayed in an HTML table column using the $row['column_name'] syntax.

      The images from the product_image column are enclosed inside the <img src = ""> tags. You’ve used the width and height attributes to resize the images to a smaller size that can fit in the HTML table column.

      In order to convert the data held by the BLOB data type back to images, you’ve used the in-built PHP base64_encode function and the following syntax for the Data URI scheme:

      data:media_type;base64, base_64_encoded_data

      In this case, the image/png is the media_type and the Base64 encoded string from the product_image column is the base_64_encoded_data.

      Next, execute the display_products.php file in a web browser by typing the following address:


      After running the display_products.php file in your browser, you will see an HTML table with a list of products and associated images.

      List of products from MySQL database

      This confirms that the PHP script for retrieving images from MySQL is working as expected.


      In this guide, you used the MySQL BLOB data type to store and display images with PHP on Ubuntu 18.04. You’ve also seen the basic advantages of storing images in a database as opposed to storing them in a file system. These include portability, security, and ease of backup. If you are building an application such as a students’ portal or employees’ database that requires information and related images to be stored together, then this technology can be of great use to you.
