Amazon Web Services (AWS) has officially entered the ad tech battleground with the launch of RTB Fabric, a real-time bidding service designed for both ad buyers and sellers. This new service represents a significant strategic push by Amazon to leverage its dominant cloud infrastructure in the advertising technology space, a direct challenge to Google Cloud Platform, which has been gaining traction among ad tech companies. The introduction of RTB Fabric is seen as a calculated effort by Amazon to further monetize its vast cloud ecosystem and capture a larger share of the digital advertising market. By offering a native real-time bidding solution on its platform, AWS aims to attract ad tech companies by providing a more integrated and efficient infrastructure for their operations. This move intensifies the competition between Amazon and Google, extending their rivalry from cloud computing directly into the lucrative ad tech sector. The development is being closely watched by industry observers to see how it will impact the market dynamics and whether it will entice ad tech firms to shift their infrastructure to AWS.
