The challenges

Reliance on VMware

Leissner’s infrastructure depended heavily on VMware for virtualization and storage, which was reliable but limited flexibility. As the business grew, concerns about stability and control over costs and future scalability arose.

Stability concerns

Changes in licensing terms and ownership introduced uncertainty, especially for smaller customers like Leissner. They questioned whether they still had control over costs, flexibility, and their future roadmap, which created strategic hesitation.

Hardware limitations

Expanding storage capacity was difficult due to vendor-specific hardware dependencies, which were expensive and not scalable. This limited their ability to grow efficiently and adapt to increasing demand.

Need for open source

The team recognized that moving towards open source infrastructure could provide more flexibility and control. However, they lacked the expertise and tools to make this transition smoothly, which posed a significant challenge.

The solutions

Dedicated Ceph training

42on provided Leissner with comprehensive Ceph training, focusing on creating a shared foundation across their team. The training went beyond basics, including hands-on scenarios, environment setup, and troubleshooting exercises. This approach helped Leissner build internal expertise and confidence in managing open source infrastructure.

Vendor-neutral approach

The Ceph training provided by 42on, emphasized vendor-neutral solutions, enabling Leissner to develop a structured, repeatable process for building their internal Ceph knowledge. This approach allowed Leissner to explore new components and future-proof their infrastructure without relying on proprietary hardware or limited platforms.

Knowledge transfer

The training provided valuable insights into open source infrastructure, empowering Leissner to make informed decisions about future deployments and upgrades.
