Executive Summary

The B2B online shop ladenbau.de the eye-catching e-commerce GmbH, together with the supporting agency RESPONSE GmbH were faced with the task of significantly improving stability, performance, and support in hosting and making it future-proof. In a joint project, the shop migrated to maxcluster – including a test cluster, performance analysis, and a closely coordinated live migration 

Since the move, the shop has been running stably and without downtime. PageSpeed increased from 58 to 72, and even items with over 100,000 variants can be accessed quickly again – a reliable foundation for further growth.

In a nutshell

Client: Blickfang E-Commerce GmbH
Industry: B2B, Interior design

Agency: RESPONSE GmbH

Initial situation

Unstable hosting and limited room for manoeuvre

Before switching to maxcluster, Blickfang E-Commerce’s online shop repeatedly suffered from outages and performance issues. For a B2B shop with demanding customer relationships, this was not only annoying but business-critical.

At the same time, the support from the previous provider met neither the customers’ expectations nor those of RESPONSE: response times were long and the answers often not very specific. On top of that, the agency could not make many necessary settings itself and regularly had to involve the host.

What was especially frustrating was that the price-performance ratio didn’t add up: the monthly fee was high, but the technical foundation was anything but convincing. It was therefore clear to everyone involved that a new hosting setup had to be found—with significantly better availability, higher performance, greater failover reliability, and true scalability for future growth.

With these requirements in mind, a structured comparison of various hosting providers began.

Selection process: top marks in the provider comparison

In the next step, several hosts were compared in detail, including well-known German providers. The offers were set side by side in an evaluation matrix to weigh technical criteria, service levels, and economic aspects against each other in a clean, transparent way.

In this evaluation, maxcluster clearly came out on top. For the  performance  maxcluster achieved the  maximum score and was also able to offer a setup that combines  high failover reliability with manageable complexity. maxcluster also led the way in scalability: the solution left plenty of room for additional projects and growth.

For RESPONSE as a Shopware agency, it was also crucial that maxcluster brings clear  Shopware affinity and the corresponding experience. The overall picture was rounded out by the  very positive personal impression from the conversations with the maxcluster team. In the end, the matrix produced a clear result—both in total points and in terms of value for money.

Why maxcluster was the right fit for Blickfang E-Commerce and RESPONSE

From RESPONSE’s perspective, this created a coherent overall picture: a host with a strong e-commerce focus, experience with Shopware setups, and an architecture that enables high-availability scenarios. The key factors were:
   

  • E-commerce and Shopware specialization
    maxcluster brings experience with complex B2B setups and Shopware 6—an important factor for a shop with many product variants.
  • Stability and fail-safety
    The planned infrastructure was clearly designed to prevent outages and keep operations stable over the long term.
  • Collaborative partnership
    RESPONSE could rely on accessible, knowledgeable contacts who not only provide infrastructure but also actively contribute to analysis and optimization.
  • Flexibility for agencies
    Configurations don’t have to go through a ticketing system for every step; in many cases, the agency can make changes directly—a noticeable day-to-day advantage.

This laid the foundation for a collaboration in which everyone involved in the project has clearly defined roles and works together as equals.

Switching our online shops to maxcluster went absolutely smoothly. Even during the first stress tests, it became clear how quickly and competently support responds – we feel extremely well taken care of technically.

Implementation

Test cluster, performance analysis and live migration

The technical implementation of the switch was carried out in clearly defined steps, with maxcluster, Blickfang E-Commerce and RESPONSE working closely together:

Requirements analysis and assessment of the current situation
At the outset, the existing infrastructure and Blickfang E-Commerce’s requirements were documented in detail. This made it possible to plan precisely which resources and setup were needed for the shop.

Setting up the test cluster and initial migration
Based on this analysis, maxcluster set up a test cluster and initially migrated the shop to this environment. The new setup could then be tested under realistic conditions without affecting live operations.

Testing phase and performance optimization
During the testing phase, Blickfang E-Commerce and RESPONSE, together with maxcluster, reviewed all key functions. Bottlenecks were identified, prioritized, and addressed in a targeted manner—especially for complex variant products with a very large number of variations.

Planning the live migration
In the next step, a clear project and timeline plan was created for the actual move, involving all parties. This made it transparent who would take on which task and when, and how the switch could be carried out as smoothly as possible.

Carrying out the live migration with minimal downtime
Finally, the live migration to the new setup at maxcluster was completed. Downtime was deliberately kept short, so the shop was unavailable only for a very brief period and could quickly be brought fully back online.

Once the shop was running entirely on maxcluster, it became clear how the changes affected stability and performance.

Results

Zero downtime and high-performance product variants

The impact of the move became apparent quickly and clearly. Particularly relevant results included:

No downtime since the switch

Since migrating to maxcluster, ladenbau.de has not experienced a single outage—downtime is zero.

Improved page speed – performance

The PageSpeed score improved from 58 to 72 – a clear indication of the environment’s improved performance.

Reliable mapping of complex product variants

Products with over 100,000 variants can now be loaded quickly once again and used in sales.

For the agency RESPONSE, this means: the shop runs reliably, responds faster, and provides enough technical headroom to implement further optimizations without constantly hitting hosting limits.

Conclusion and outlook

By switching to maxcluster, Blickfang E-Commerce and RESPONSE have taken the B2B Shopware 6 shop ladenbau.de to a new technical level. From a project perspective, the key effects can be summarized as follows:

  • Stable operation without downtime as the basis for reliable relationships with B2B customers.
  • Noticeably better performance, measurable in page speed and tangible in users’ day-to-day experience.
  • Future-proof infrastructure, that enables growth and further expansion stages of the shop.
  • Relief for the agency, because hosting and further development now work together cleanly and require less coordination effort.

On this basis, the shop can now continue to grow—whether by expanding the product range, adding additional features, or implementing targeted measures to optimize conversion. The technical foundation is in place, and the collaboration between the agency and the host provides enough room to make use of these opportunities step by step.
