Why Every Site Owner Should Consider Google Cloud Hosting

WordPress now powers over 40% of all websites, from humble hobby blogs to major online publications. But as your audience grows, the legacy hosting platforms most people start out on can struggle.

Painfully long load times destroy site speed and become a barrier to engaging visitors. At peak traffic, resources max out leading to expensive downtime. Without expert optimization, a typical WordPress site slows to a crawl by the time it reaches just 100,000 monthly visitors.

The solution? Migrating to the cloud – and Google Cloud Platform specifically – gives sites an "endless scale" advantage traditional hosts can never match…

Blazing Fast Site Speeds

Google Cloud‘s state-of-the-art infrastructure offers WordPress sites 50-80% faster load times compared to mid range hosts. SSD disks, cutting-edge processors and multiple global edge cache locations translate to much snappier visitor experiences.

According to Google analytics, 53% of mobile site visitors abandon pages that take over 3 seconds to load. By slicing load times to under 1 second with GCP, sites can expect dramatic jumps in engagement and conversions.

Instant and Limitless Scalability

Another key benefit is auto-scaling groups that spin up more cloud server capacity automatically to handle huge traffic spikes. Where most shared hosts crash at a few thousand visitors, your WordPress site can smoothly absorb 100k, 500k or even a million visitors without blinking.

This makes Google Cloud perfect for sites anticipating viral content, promotions or a surge in advertising. Capacity scales up and down on demand so you only pay for exactly the resources used.

Beefed Up Security Included

A custom LEMP stack configuration also allows hardcore security measures like OS hardening and WAF protection many managed hosts lack…

Let‘s dive in and get your Lightning-fast WordPress site running on Google Cloud in under 30 minutes!

Choosing Your Ideal Google Cloud Machine Type

Google Cloud offers a spectrum of virtual machine (VM) packages tailored to different needs. The optimal choice comes down to computing power, memory, storage and network capacity required.

I recommend considering these GCP machine types to start:

Personal/Small Business Sites – For hobby blogs, small commercial sites or prototypes handling under 10k visitors per month, an e2-medium (2 vCPUs, 4GB memory) works excellently. This provides enough power for most standard sites at just ~$25 monthly.

High Traffic SMB Sites – For small business sites anticipating 25k+ visitors per month, I suggest at least a n2-highmem-2 (2 vCPUs, 16GB memory). The extra RAM helps handle increased database demands and caching for ~$65/month.

Enterprise Scale Publishing – Larger news sites, online magazines and commercial sites expecting 6 figure+ monthly visitors should consider a minimum n2-highcpu-8 (8 vCPUs, 32GB memory) or larger. This allows ample capacity for heavy loads and multimedia content.

I always advise new sites start smaller and scale up machines incrementally to manage expenses. The beauty of cloud hosting is adding more resources is painless whenever traffic growth demands it.

Now let‘s launch your stack!

Launching and Securing Your Google Cloud Instance

With your ideal machine selected, it‘s time to spin up your cloud server. Just log into the Google Cloud Console and:

  1. Navigate to Compute Engine > VM Instances

  2. Click the Create Instance button

  3. For the boot disk, choose Ubuntu 18.04 LTS or 20.04 LTS. Use an SSD disk for optimal performance.

  4. Under Firewall, check Allow HTTP and HTTPS traffic at a minimum.

  5. Adjust any other settings for your requirements and click Create.

Within minutes you‘ll have a fresh Ubuntu server ready to install WordPress on!

Now before we proceed, it‘s vital we lock down remote access and enable some security barriers. Here are key steps I recommend:

  • Setup SSH key based authentication only. Disable password logins.
  • Restrict SSH/management ports to authorized networks only.
  • Create non-root admin user accounts with sudo privileges
  • Ban root login for better protection

OK – with firewalls and user accounts configured, we‘re ready to install our…

Web Server Stack – Nginx, PHP and MariaDB

There are multiple paths to installing WordPress. I prefer using Nginx paired with PHP7.4 and MariaDB rather than Apache for maximum site performance. Here is an overview of the process:

Step 1 – Install Nginx, PHP extensions and compilers via APT:

sudo apt update
sudo apt install nginx php7.4 php7.4-fpm php7.4-mysql php7.4-xml php7.4-gd

Step 2 – Tweak the php-fpm config for increased performance: 

vim /etc/php/7.4/fpm/php.ini

Apply changes like:

  • Set cgi.fix_pathinfo=0
  • Raise memory limits
  • Enable OpCache with cache size of 512 MB

Save config and restart php-fpm.

Step 3 – Next install MariaDB, set the root password and create a separate DB for WordPress:

sudo apt install mariadb-server
sudo mysql_secure_installation
# Follow prompts to set root password & security options 
sudo mysql -u root -p 
CREATE DATABASE wordpressdb;

This completes the LEMP stack installation! Now we can deploy WordPress…

Setting Up WordPress for Speed

With Nginx+PHP ready, WordPress can be installed quickly via CLI:

Step 1 – Grab latest WordPress and extra plugins:

cd ~  
wget http://wordpress.org/latest.tar.gz
tar xzvf latest.tar.gz
rm latest.tar.gz
mv wordpress site
cd site

Step 2 – Populate wp-config.php with database details: 

cp wp-config-sample.php wp-config.php
vim wp-config.php

Add your unique keys and salts along with the DB name, user and password you configured earlier.

Step 3 – Run the WordPress installer:

sudo wp core install --url=example.com --title=Site --admin_user=admin --admin_password=complexpassword [email protected]

Once the installer completes, your WordPress backend is ready!

Now for the secret sauce – enhancing speed with Redis for object caching…

Installing Redis for Lightning Fast Caching

To take site speed to the next level, I recommend installing Redis and the WP Redis plugin:

# Install redis 
sudo apt install redis-server

# Connect to WP CLI 
sudo wp shell 

# Install WP Redis plugin
wp plugin install redis-cache

# Enable plugin
wp redis enable 

# Flush rewrite rules  
wp rewrite structure ‘/%year%/%monthnum%/%postname%/‘

# Regenerate cached files
wp redis update

With Redis enabled, static assets like pages and media can be stored in ultra fast in-memory caches. This bypassing slow disk access speeds for 50x+ faster delivery!

We‘re all set server-side. Now for crucial frontend optimization…

Tuning WordPress Performance From Admin Dashboard

Beyond server configuration, much can be done performance-wise from within the WordPress admin:

  • Under Settings > General switch default theme to a lightweight option like Twenty Twenty. Disable unused widgets.

  • Under Media Settings, set Large Size images to 1024px max.

  • Under Privacy Settings disable embedding 3rd party assets like Twitter, YouTube etc. Host locally.

  • Install the free Jetpack or WP Performance Score plugins to analyze site speed hot spots.

  • Enable GZIP compression in either your wp-config.php or even server Nginx configs.

Combining cloud power with diligent speed optimization, most sites should achieve 95+ scores on Google PageSpeed Insights and sub-500ms load times.

But it never hurts to confirm using load testing…

Stress Testing WordPress on Google Cloud

The best way to validate your shiny new site is pressure testing it against live user loads. I routinely use free tools like Loader.io for initial benchmarks before launch.

Loader.io can simulate up to 15k concurrent users against your home page to identify performance limits. Simply:

  1. Visit loader.io and enter your site URL

  2. Set Users to 1000, Duration 60s, Frequency ASAP

  3. Click Start Load Test

Watch as loader.io unleashes a flood of visitors against your stack! Monitor HTTP response timings and error rates closely. Tweak Nginx, PHP and even your WordPress configuration based on insights uncovered.

You‘ll be amazed seeing Google Cloud easily absorb crushing volumes without complaint. But capacity can always be right-sized later if demands continue rising post launch.

Scaling Smartly Through Site Growth Phases

The cloud makes adapting to site traffic growth refreshingly easy. Just monitor your Compute Engine > VM Instances page in the Google Cloud console.

Keep utilization of your CPUs, RAM and disk space under 80% for optimum performance. The second you see resources edging consistently higher:

  • Navigate to your VM Instance details page
  • Click Edit
  • Choose a machine type with more capacity
  • Save changes

Within minutes your VM will resize to the new specifications automatically, sans any site disruption!

Rinse and repeat as future traffic increases justify it. And consider leveraging auto-scaling groups to really future proof.

Final Word – Start Your Journey to Cloud Hosting

Hopefully this guide served as the push needed to get your WordPress site into lightspeed Google Cloud territory just like the pros!

No more resource limitations or exorbitant commercial hosts fees. Just pure power, speed and scalability to satisfy millions.

Of course mastering configurations takes practice. But the journey is well worth it!
