This research explores the security landscape of the Internet-facing services hosted in Amazon AWS, Microsoft Azure and Google Cloud Platform. Public cloud is becoming increasingly popular and the reported total spending on cloud infrastructure grew 45.6% in 2018. Amazon AWS maintained its lead with a 31.3% share of the Cloud Service Provider (CSP) market, followed by Microsoft Azure with 16.5%, and Google Cloud Platform, with 9.5%. CSPs offer various “as-a-service” models that give businesses agility and flexibility to scale operations without worrying about the IT infrastructure. However, a single insecure configuration can put the entire infrastructure at risk.
