Key points:
- Cloud resource costs reduced by double-digit percentages through a FinOps approach
- Effective optimization and monitoring of Kubernetes clusters in real time
- Better performance and stability of applications on AWS
- Flexible solutions adapted to complex IT infrastructures
- Long-term savings and technical readiness for what comes next
In today’s automotive industry, using cloud technology efficiently is essential to staying competitive. Many companies struggle to optimize their Kubernetes clusters, which often leads to over-provisioned resources and unnecessary cost. Adopting a FinOps approach is becoming an increasingly important answer, because it allows better cost control and more efficient use of cloud resources.
The client
Volkswagen Group, one of the world’s largest carmakers, is known for its innovation and technical progress. The company runs an extensive IT infrastructure that includes Kubernetes clusters on a Container as a Service (CaaS) platform in Amazon Web Services (AWS), supporting a broad range of applications and services across the group.
The problem: over-provisioned resources and high costs
VW Group faced a serious problem with over-provisioned resources in its Kubernetes clusters. Analysis showed that CPU and memory allocations in the clusters could be reduced substantially. This was most apparent when applications scaled, resulting in unnecessary resource consumption.
The inefficiency identified opened up the opportunity to reduce costs by millions of euros a year, depending on the AWS plan chosen. Optimizing memory and CPU lowered operating costs and also made capacity planning and infrastructure scaling more effective.
Wasted resources complicated the rollout of new services and prevented VW Group from getting the full value of its cloud infrastructure. Using cloud resources more efficiently was key to strengthening its competitive position in a fast-changing industry.
VW Group set the following goals for optimizing its Kubernetes clusters:
- Substantially reduce over-provisioning of resources in the Kubernetes clusters.
- Minimize the unnecessary costs of unused resources.
- Introduce an effective system for monitoring and managing cloud resource use.
- Implement a long-term strategy for cost optimization and resource use.
- Improve the overall efficiency and performance of the Kubernetes platform.
The solution: a FinOps approach
Aspecta designed a complete solution based on a FinOps approach, delivered in three phases:
The short-term phase covered the rapid deployment of FinOps tools and a detailed analysis of resource consumption. It was designed to start immediately and ran for several weeks. During this period the Aspecta team identified the key areas of inefficiency and produced a detailed map of resource use across all of VW Group’s Kubernetes clusters.
The medium-term phase focused on adopting the FinOps approach within the development teams, the application owners, and the CaaS team. It included a workshop aimed at changing the culture and the way cloud resources are used. The teams learned how to plan and optimize resource use for their applications and services.
The long-term phase concentrated on continuous improvement and on establishing best practices for Kubernetes management. It included automated tools for monitoring and optimization, regular audits of resource use, and a system for ongoing training to keep the teams current on cloud optimization.
Short-term phase:
- rapid deployment of FinOps tools and a detailed analysis of resource consumption
- identification of the key areas of inefficiency
- a detailed map of resource use across all of VW Group’s Kubernetes clusters
Medium-term phase:
- adoption of the FinOps approach within the development teams, the application owners, and the CaaS team
- training the teams to plan and optimize resources for applications and services effectively
Long-term phase:
- establishing best practices for Kubernetes management
- automation of monitoring and optimization
- a system for keeping the teams current on cloud optimization
Several challenges came up during the implementation, and we addressed them as follows:
- Initial resistance from teams: one of the main challenges was initial resistance from some teams to changes in established practice. This was overcome through intensive communication and by demonstrating the concrete benefits of the new approach.
- Infrastructure complexity: the complexity of the existing VW Group infrastructure made a single approach to optimization difficult. The Aspecta team created a flexible framework adapted to the specific needs of different parts of the organization.
- Technical issues: issues such as integrating the new FinOps tools with existing VW Group systems were addressed through close cooperation with the client’s IT team and by introducing changes gradually to keep disruption to a minimum.
Results: lower costs and efficient use of resources
The FinOps approach and the optimization of the Kubernetes clusters delivered significant results for VW Group:
- Savings on CPU and memory
CPU and memory spend was reduced by double-digit percentages, which represents monthly savings in the tens of thousands of euros. - Better performance and stability
Applications running on the CaaS platform are now more stable and perform better. - Clearer view of resource use
The teams gained more effective tools for capacity planning and can roll out new services faster. - A positive effect on culture
The teams started optimizing resource use actively, which raised the overall efficiency of VW Group’s IT operations.
Conclusion
The Kubernetes cluster optimization project for VW Group shows how a strategic approach to managing cloud resources can deliver significant financial savings and improve the overall efficiency of an IT infrastructure.
The FinOps approach solved the immediate problem of over-provisioned resources and laid the groundwork for long-term optimization and effective cost management in cloud computing.
The project underlines how important continuous optimization and monitoring are in a dynamic cloud environment. For VW Group it means immediate financial savings and better readiness for the technical demands ahead in a fast-changing industry.
