webbar, a software company specializing in robust backend and infrastructure development, was ready for its next strategic step: scaling its modern microservices architecture. The team has been working together for 18 years, initially as part of the bitsinmotion GmbH, and for the past 3 years under the webbar GmbH banner.

webbar initially hosted applications on a Managed Container Platform (specifically, Digital Ocean App Platform). While easy to use at first, this setup quickly introduced critical limitations concerning performance, cost-efficiency, and operational control necessary for enterprise requirements.

The development team at webbar was highly skilled in software but lacked Operations expertise (with no dedicated "Ops persons") for a cloud-native transformation. Recognizing the need for Kubernetes to ensure future scalability and cloud flexibility, webbar sought external expert assistance.

By leveraging the mogenius Platform and Professional Services, webbar was able to bridge the internal skills gap, enabling a rapid, zero-downtime transition to a high-performance Kubernetes environment. This collaboration allowed webbar's engineers to focus on creating business value, rather than managing infrastructure toil.

The Challenge

To continue its growth and meet sophisticated client demands, webbar needed to adopt Kubernetes but was simultaneously constrained by its existing infrastructure and limited internal expertise.

Technology Abstraction and Control Loss:

The previous Managed Container Platform provided a simplified interface, but this abstraction came at the cost of essential control and visibility. This limited ability to configure the underlying infrastructure directly was unsuitable for webbar’s complex microservices and created compliance and security auditing challenges.

The DevOps Skill Gap:

webbar’s highly competent development team, experienced in Docker and Docker Swarm, was not equipped to build and maintain a Kubernetes platform. The company saw the value of Kubernetes but recognized the prohibitive cost and difficulty of hiring a team of specialized DevOps engineers just for platform maintenance. The strategic goal was to implement k8s without requiring deep, expensive re-skilling.

Severe Performance and Cost Bottlenecks:

The Managed Container Platform experienced weak compute performance and high operational costs that scaled poorly. The webbar team noted distinct application performance issues where local development was significantly faster than the production environment, which they attributed in part to inefficient scheduling processes on the former platform. Nodes frequently ran at 100% capacity, risking service degradation and scaling failures.

Operational Blind Spots:

Deployment processes were inefficient and non-transparent, sometimes taking up to 15 minutes, often resulting in crashes without clear diagnostic information. The platform lacked satisfactory log aggregation capabilities, creating operational overhead and poor observability into the complex microservices environment.

Vendor Lock-in and Agnosticism:

The old solution made it difficult for webbar to achieve its goal of cloud agnosticism. Serving clients who required deployments on custom infrastructure (like AWS or on-premise) was hampered, adding a significant 20–30% overhead per project.

Why mogenius?

webbar chose mogenius for its unique ability to deliver a robust technology platform combined with expert services, solving the skills gap while achieving all strategic Non-Functional Requirements (NFRs).

Platform and Professional Services:

mogenius provided a solution that addressed webbar's skills shortage and non-functional requirements. mogenius delivered the internal developer platform (IDP) layer, allowing webbar to adopt a robust Kubernetes foundation without the inherent architectural and maintenance toil. The professional services team acted as the client’s extended platform team, accelerating the adoption of best practices.

High Control and Visibility:

Unlike many 'black box' solutions, the mogenius platform offered developers the necessary visibility and control. It included out-of-the-box observability (monitoring, logging, pipelines, status information) and granted developers total control over essential components, such as underlying GitHub pipelines via starter templates.

Cloud and Infrastructure Agnosticism:

The open-source mogenius Operator connects to any existing Kubernetes cluster (hyperscaler, partner, or on-premise), ensuring webbar maintains the freedom to deploy anywhere, a crucial requirement for their client-facing business model.

Responsive Partnership:


mogenius demonstrated flexibility and speed, quickly addressing non-standard requirements and complex edge cases (like multi-tenant hostname setups and wild card certificates). This close and responsive partnership was key to ensuring a smooth, tailored migration.

The mogenius Solution in Action

mogenius delivered its solution by deploying the mogenius Operator onto webbar's new Kubernetes cluster via a simple Helm chart installation.

  • Automated and Transparent Deployment and CI/CD:
    The webbar team leveraged mogenius's starter templates for GitHub Actions, enabling them to deploy quickly and efficiently using native Kubernetes concepts like rolling updates. This provided developers with complete transparency into their pipeline: when troubleshooting configuration issues, they could resolve them rapidly, saying: "I knew why" the deployment failed.

  • Developer Enablement:
    The mogenius platform provided the necessary Kubernetes functionality (handling namespaces, ingress for routing, etc.) through a simple interface, effectively unifying the developer and operations worlds. This allowed developers to manage their applications’ lifecycle without demanding they become Kubernetes cluster administrators.

  • Infrastructure Control:
    mogenius provided the tools to manage critical infrastructure components previously abstracted away by the old container service, such as the Ingress controller for routing and the automated handling of wildcard certificates.

  • Rapid Migration:
    Leveraging their pre-existing container knowledge, webbar executed the complete migration in less than a week. The transition was conducted without any customer-facing downtime by utilizing both the old and new platforms simultaneously and shifting the traffic via a load balancer switch.

The Results & Benefits

The transition to Kubernetes, built and managed with mogenius, delivered immediate and significant returns on investment:

  • Dramatic Performance Increase:
    The performance of applications improved by an order of magnitude, becoming approximately 10 times faster due to dedicated resources and optimized scheduling. Time-intensive, long-running processes, such as PDF creation, were reduced dramatically from roughly 20 seconds to 1–2 seconds.

  • Achieved Real Scalability:
    The new dedicated Kubernetes environment runs fast and provides genuine, necessary scalability, ensuring that complexity does not increase proportionally with the scale of the application.

  • Strategic Agnosticism and Future-Proofing:
    webbar gained the required level of agnosticism, allowing them to retain control and the freedom to deploy on any infrastructure required by future business needs or clients.

  • Empowered and Autonomous Teams:
    Developers are now more productive, with easy self-service access to diagnostics and required tooling. The team is fully focused on software development and delivering business value.

  • Enhanced Reliability:
    The strategic decision proved its value in stability, with webbar’s team confirming smooth, reliable operations, noting that they "never really had any form of WTF moment" after the transition.

Conclusion

webbar successfully executed a strategic infrastructure transformation, moving from the restrictive limitations of the former Managed Container Platform to a robust, high-performance Kubernetes foundation. The mogenius Platform and Professional Services were key, providing the missing internal developer platform layer and the necessary expertise to navigate the complexity of k8s. This partnership enabled webbar to meet sophisticated client requirements and fulfill its long-term strategic goals for control, performance, and cloud agnosticism, solidifying its reputation as a leading development company.

FAQ

We have a DevOps skill gap. How does mogenius help our existing developers use kubernetes without extensive re-skilling?

mogenius abstracts away the complexity of raw kubernetes. Our platform provides a self-service interface and starter templates for CI/CD, enabling developers to use core kubernetes concepts like rolling updates, logging, and monitoring instantly, without needing deep cluster expertise or writing complex YAML.

Why did webbar choose to move from a Managed Container Platform (PaaS) like Digital Ocean App Platform?

The PaaS provided ease of use but restricted critical factors like performance, control, and observability. For a growing microservices architecture, webbar needed dedicated compute power and true cloud agnosticism, which the black-box nature of the PaaS could not deliver efficiently.

What is the primary difference between using the mogenius platform and trying to build an internal Platform Engineering team?

Building an internal Platform Engineering team is expensive, time-consuming, and difficult due to the ongoing DevOps skill shortage. The mogenius platform and Professional Services allow you to immediately leverage a fully built, maintained, and continuously improved platform (our product) combined with expert guidance (our service), achieving the benefits of Platform Engineering instantly.

How does the mogenius platform ensure cloud agnosticism and prevent vendor lock-in?

mogenius is designed to be fully cloud-agnostic by operating directly on any Kubernetes cluster, whether hosted on a public cloud, private infrastructure, or bare metal. The mogenius Operator integrates with clusters from AWS, GCP, Azure, or on-prem environments in the same way, providing a unified control plane and consistent developer experience.

Through its GitOps-based workflows, Helm chart and YAML deployment support, and open integrations (e.g., GitHub Actions, Prometheus, ArgoCD), mogenius avoids any dependency on proprietary cloud services. This means teams can migrate workloads freely between environments without changing deployment pipelines or tooling.

A real-world example is described in the Cloud-Agnostic Kubernetes Migration case study, where a company reduced costs by 90% by migrating from a hyperscaler to bare metal using K3s, Ansible, and the mogenius operator, all while maintaining the same CI/CD workflows and developer experience.

In short, mogenius abstracts Kubernetes management, not the infrastructure layer, ensuring you keep full control and can move or scale workloads across any provider without vendor lock-in.

How is the mogenius Platform different from a standard Managed Kubernetes offering?

Managed Kubernetes (like EKS or AKS) provides and maintains the underlying cluster infrastructure. The mogenius Platform is an internal developer platform (IDP) layer that sits on top of any existing cluster. It provides the necessary developer workflows, observability, CI/CD automation, and control for Day-2 Operations, regardless of the underlying infrastructure provider.

What is the main difference between Managed Kubernetes and an Internal Developer Platform (IDP)?

A Managed Kubernetes solution handles the infrastructure and cluster management for you. An IDP, like the mogenius Kubernetes Manager, is a layer on top of your Kubernetes cluster that simplifies Day-2 operations and provides a self-service interface for developers, making it easier for them to deploy and manage applications.
