One of the easiest mistakes in technology is to assume that replacing an existing system is the same as solving the customer’s problem.
During an assignment, I traveled to Oslo, Norway, as a presales solutions architect.
The company I was working with provided hosting services to small businesses and individual customers. Its existing hosting environment was built around Linux and other open-source technologies.
The company had an established customer base that was well served by its existing technology. It wanted to expand its services by adding capabilities based on Microsoft technologies.
From the technology vendor’s perspective, the opportunity initially appeared straightforward: replace the existing environment with its own products.
But that was not what the customer actually needed.
Its existing customers were loyal to the services and technologies they already used. Forcing those customers onto a different platform could have put much of the hosting company’s existing business at risk.
The real question was not, “How do we eliminate Linux?”
It was, “How do we add new capabilities without destroying what already works?”
My architectural recommendation was to keep the existing Linux environment for the customers who wanted it and add a separate environment for customers whose needs were not currently being met.
The client was very pleased with the recommendation. It differed from the original expectations, but insisting on a complete replacement could have jeopardized the opportunity.
By allowing the technologies to coexist, the hosting company could protect its existing business while expanding into a new market. The technology vendor could also gain business it otherwise might not have won.
That experience reinforced an important lesson: the responsibility of a solutions architect is not simply to promote a preferred product.
It is to understand the customer’s business, preserve what is already working, and recommend the solution that creates real value.
Sometimes the best solution is not replacement.
Sometimes it is coexistence.
