In technology, the most sophisticated solution isn’t always the best one. Sometimes, keeping things simple is the smartest engineering decision.
A Real Experience
In one of my previous roles, I joined a company as Head of DevOps. At the time, I was the only dedicated technical person, responsible for everything from infrastructure and hosting to deployments, troubleshooting and maintaining the company’s websites.
One of my responsibilities was revamping several WordPress websites. During discussions about the infrastructure, the CTO asked me an interesting question:
“Would it make sense to move all our WordPress websites to a Kubernetes cluster?”
My answer was consistently the same: For our requirements, Kubernetes would be overkill.
Not because Kubernetes isn’t a great technology. It absolutely is. But just because we can use something doesn’t necessarily mean we should.
Does WordPress Really Need Kubernetes?
Kubernetes (K8s) is a powerful container orchestration platform designed to deploy, manage and scale applications. It’s particularly valuable for complex environments involving microservices, distributed systems and applications requiring advanced scaling capabilities.
But WordPress is different.
Most corporate websites, blogs and small-to-medium business websites can run perfectly well on a properly configured Linux server with Apache or Nginx, PHP-FPM and MySQL or MariaDB.
Add caching, a CDN, automated backups, monitoring and a reliable deployment process, and you already have a solid hosting environment.
You don’t need Kubernetes to achieve good performance, security or reliability.
The Pros and Cons
Kubernetes certainly offers advantages:
- Scalability: Automatically scale application workloads when needed.
- High availability: Help distribute workloads across multiple nodes.
- Deployment automation: Support rolling updates and consistent deployments.
- Standardisation: Manage multiple containerised applications through a common platform.
However, those benefits come with additional responsibilities:
- Complexity: Clusters, pods, ingress controllers, networking and persistent storage all require configuration.
- Maintenance: More components mean more monitoring, troubleshooting and upgrades.
- Costs: Additional infrastructure and engineering time can increase operational expenses.
- WordPress-specific challenges: Media uploads, databases, plugins and shared storage require careful planning when running multiple replicas.
For an organisation running several relatively straightforward WordPress websites, these disadvantages may outweigh the benefits.
What Would I Focus On Instead?
Rather than introducing unnecessary infrastructure complexity, I would prioritise:
- Reliable hosting with appropriately sized resources.
- Proper caching and website performance optimisation.
- Security updates and access controls.
- Automated deployments using Git and CI/CD.
- Regular backups and tested recovery procedures.
- Monitoring and alerting.
These improvements provide real value without introducing an entire orchestration platform.
Of course, if an organisation already operates Kubernetes, has an experienced team and a clear requirement for it, running WordPress on that platform can make sense.
The decision should always be driven by actual business and technical requirements.
Sometimes Less Really Is More
Throughout my career, I’ve learned that good engineering isn’t about implementing the latest or most complex technology. It’s about understanding the problem and selecting the most appropriate solution.
Sometimes that means Kubernetes, distributed systems and sophisticated cloud infrastructure. Other times, it means a well-configured Linux server running WordPress reliably and efficiently.
The best architecture isn’t necessarily the most complex one. It’s the one that solves the problem without introducing unnecessary complexity.
At Proweb, this is how I approach cloud infrastructure, DevOps and technology consultancy: practical solutions that deliver real business value.
