Why go serverless?

Gone are the days when we had to worry about provisioning and managing servers for our websites. Enter serverless architecture, the latest buzzword in the tech community. With serverless, you no longer have to bear the burden of maintaining servers, configuring software, or worrying about scaling issues. Instead, you can focus on what really matters – crafting exceptional content and providing an amazing user experience.

What’s so special about serverless cloud infrastructure?

First and foremost, serverless architecture allows you to wave goodbye to all those sleepless nights spent worrying about server crashes. With serverless cloud infrastructure, your WordPress site is hosted on a managed platform that takes care of all the nitty-gritty details for you. It automatically scales up or down based on the traffic demands, ensuring your site stays lightning-fast, regardless of the number of visitors.

The benefits


With serverless cloud infrastructure, you only pay for the resources you actually use. There are no fixed monthly fees or upfront costs, making it an ideal solution for startups and small businesses with limited budgets.


As your website grows and attracts more traffic, serverless architecture scales effortlessly to handle the load. No more waking up in the middle of the night worrying about sudden spikes in traffic overwhelming your servers and causing your site to crash. Your WordPress site will remain resilient and highly available.

Simplify your maintenance

Say goodbye to tedious server management tasks. Serverless infrastructure handles all the server maintenance and software updates for you, allowing you to focus on creating amazing content and engaging with your audience.

Enhanced security

Serverless cloud providers invest heavily in security measures to protect their infrastructure. By leveraging their expertise, you can rest assured that your WordPress site is safeguarded against common vulnerabilities and threats.


Serverless architecture encourages a modular approach, making it easier to develop and deploy new features for your WordPress site. It also provides seamless integration with various APIs and services, empowering you to extend the functionality of your site effortlessly.

Host with the most

When it comes to hosting, there are two versions that are superior to the traditional way people host:

Shared hosting typically consists of larger servers each with hundreds or thousands of customers sharing a single IP address. It can be slower because each website competes for the same resources (such as processing power and memory). More expensive shared hosting plans limit the number of websites on a particular server and sometimes move websites around to balance the load, but can still be slow if the other “neighbouring” websites get a lot of traffic or are attacked.

Dedicated hosting includes our current hosting. It can mean either an entire physical machine sitting in a data center, or as in our case, a virtual private server in the cloud such as on Google Compute, Digital Ocean Droplets, and Amazon Lightsail/Elastic Compute. In both cases, the resources are specifically allocated for your website alone and are not shared amongst others, including a dedicated IP address. This is typically more reliable as long as the resources are adequate to handle the traffic needs of the website. None of these solutions offer the same level of performance, reliability, speed, and scalability.

Pantheon and Google Kubernetes

We’ve spent the last couple of months researching this and have since moved our own website over. It is crazy fast and the right, long-term solution for sites that are growing at an exponential rate or about to see large spikes in traffic.

Kubernetes is a type of serverless hosting that uses software “containers” instead of traditional hosting servers. These containers run on cloud infrastructure, without being tied to specific resources (such as CPUs and RAM). This provides infinite and immediate scalability and this is how huge platforms such as Shopify manage traffic without ever experiencing downtime. See https://cloud.google.com/learn/what-is-kubernetes.

We spent a lot of time looking into Google App Engine and Kubernetes ourselves, however doing this without Pantheon would require more cost, development, time, and frankly—expertise, than we have to invest. Pantheon manages the infrastructure so that we can focus exclusively on development (and marketing). See https://pantheon.io/webops.

Our conclusion: Our website is extremely (and noticeably) fast since moving over to Pantheon.

In development

Another critical reason we think Pantheon and serverless cloud infrastructure makes sense, especially for those with high traffic, is that Pantheon provides dedicated environments for development, testing, and live websites. This means we can simultaneously develop and test versions of your website without interrupting your subscribers. Otherwise, we’d have to make “hotfixes” to the live website and hope those fixes don’t interrupt customers. This is not the best practice for a live website.

Our conclusion: It’s a safer and less stressful way to test versions of your site.

Core Web Vitals

A set of metrics called Core Web Vitals, or CWVs, was created by Google to assist publishers in enhancing the functionality of their websites for the benefit of site visitors. They measure and evaluate the speed, responsiveness, and visual stability of websites and give more opportunities for a rankings boost, as long as you use them properly. Using serverless cloud infrastructure will help with a more positive outcome on that front. Learn more about them here.

But not without its challenges

While serverless cloud infrastructure for WordPress is undoubtedly a game-changer, it’s important to acknowledge a few potential challenges. For example, if your WordPress site relies heavily on custom plugins or requires complex server configurations, you may need to adapt them to fit within the serverless ecosystem. Additionally, some serverless platforms have limitations on long-running processes or file storage, so be sure to know the specific requirements of your site before making the switch.

The future of hosting

The future of hosting is here, and it’s serverless cloud infrastructure. Your website is a mission-critical platform that your customers, staff, and business rely upon. Hosting should become a competitive advantage, not merely an expense.

Embrace this cutting-edge technology to get an array of benefits – from scalability and cost-effectiveness to simplified maintenance and enhanced security. By leaving server management to the experts, you get to focus on what really matters – delivering exceptional content and building meaningful connections with your audience.
