The text discusses the challenges faced by a European Ad Technology company when scaling its system, which led to increased infrastructure costs and decreased performance. The initial approach of using PHP and MongoDB on AWS resulted in high costs due to MongoDB's inability to handle large volumes of data and queries efficiently. After attempting to use Redis for indexing document searches, the developers suggested scaling MongoDB further, but this was deemed too expensive by the business owner. An architectural analysis conducted by Asteriosoft proposed a solution by migrating the workload to Aerospike, a specialized tool that provides faster response times for key-value storage and statistical data processing. This resulted in significant cost savings and improved system performance, allowing the company to increase traffic without additional infrastructure investments. The example highlights the importance of utilizing specialized tools and conducting deep architectural analysis to resolve accumulated problems and reduce costs.
