There are over 1.9 million merchants selling on our client's international marketplaces. Collectively, these merchants are responsible for selling about 1/3 of all items ordered from the company worldwide. The revenue and free cash flow generated by the business is at the same proportions. The business continues to grow at a high rate year-over-year and there are several initiatives that will continue to drive this trend.
Technology and self-service automation are cornerstones for this growth. To achieve this, the correct database infrastructure and architecture is an increasingly critical part of enabling the business to move fast and scale while maintaining customer trust. Over 90% (over 160 instances support 50+ services and application) of the databases support OLTP operations and receive millions of requests per week. Immediate openings are available for talented and driven DBAs that have a good combination of operational, scripting and architectural knowledge. Our client's databases are generally large-scale systems that can range in the terabytes. The challenge is to ensure that all of this data is always available and find new ways to continuously increase availability while considering total cost of ownership and operational overhead.
