Business context
When the client approached Onix, he already had established a digital magazine. However, its technology infrastructure began to pose challenges to his business.
A digital magazine must deliver multimedia content to a large audience while maintaining a high-quality user experience. As readership grew, so did the pressure on the owner to scale the online magazine’s infrastructure to meet increasing demands.
This is how our client formulated his request: to improve his website performance, ensure scalability, and increase the security level.
The Onix team was responsible for:
Gathering requirements to define objectives and project scope
Ensuring an effective and transparent development process
Deploying WordPress on Kubernetes using Gitlab to ensure our client's website is always available, scalable, and secure
Implementing reliable advanced technologies to ensure the website’s high performance and proper functioning
Looking for a reliable DevOps services company?
After analyzing our client’s business and needs, Onix’s team decided to use Kubernetes to deploy his WordPress website.
Kubernetes helps address the challenges our client faced by providing tools for managing containerized applications across a distributed infrastructure. Kubernetes enabled us to scale applications and infrastructure automatically without incurring significant overhead or downtime.
Our specialists also automated deployment, management, and monitoring tasks, freeing up valuable resources for delivering content and engaging with readers.
Set up a Kubernetes cluster
The first step was to create a Kubernetes cluster on the cloud provider, Amazon Web Services, - Amazon EKS. This cluster will be used for hosting the WordPress application.
Create a Docker image for WordPress
Once we set up our Kubernetes cluster, the next step was to create a Docker image for a WordPress application. This image will contain all the necessary files and configurations to run the digital magazine.
Deploy WordPress on Kubernetes
We created a Kubernetes manifest file that defines the application deployment. This file contains information about the Docker image we created in the previous step and how many replicas of the WordPress application we want to run.
Use Kubernetes services for load balancing
To ensure that our client’s WordPress application is highly available and scalable, we used Kubernetes services to balance traffic between the application replicas.
Set up persistent storage for WordPress
WordPress requires persistent storage to store data like blog posts, images, and plugins. We used Kubernetes persistent volumes to provide persistent storage for the online magazine.
Use Kubernetes Secrets to manage sensitive data
Kubernetes Secrets is a secure, scalable, and easy way to manage sensitive information and protect critical data like database passwords and API keys. It helped enhance the website’s security, simplify management, and automate sensitive data control.
Issues we solved
Scalability
Kubernetes facilitates easy scaling of the digital magazine website by automatically adding or removing resources based on demand.
As traffic spikes, additional resources are allocated to handle the increase in demand, ensuring a smooth user experience.
Automation
Kubernetes automates many tasks related to managing digital magazine applications, such as scaling, updates, and deployments.
Automation helps reduce manual work, allowing our client’s business to operate more efficiently.
High availability and resilience
Kubernetes provides enhanced availability and resilience for our client’s digital magazine by ensuring redundancy across multiple nodes.
If one node fails, traffic is automatically redirected to other available nodes, ensuring service continuity.
Core technology stack we used
Docker,
AWS,
Elastic Beanstalk,
Elasticsearch,
WordPress,
Memcached
During the cooperation, the Onix team proved to be:
Professional
Open
Reliable
Predictable
Transparent
Results
By using the Kubernetes engine, our client now has a more robust and scalable infrastructure, better management of resources, and the ability to improve user experience.
Moreover, the use of Kubernetes helped us optimize the use of the client’s available resources and cut infrastructure costs while ensuring that the WordPress app runs efficiently.
