The latest IDC research report indicates the market share of leading public cloud service providers in 2019.
Amazon Web Services (AWS), Microsoft, Salesforce, Google and Oracle are the leading public cloud service providers in 2019.
The public cloud services revenue, including Infrastructure as a Service (IaaS), Platform as a Service (PaaS), and Software as a Service (SaaS), grew 26 percent in 2019 to $233.4 billion, according to the International Data Corporation (IDC).
The top 5 public cloud service providers (AWS, Microsoft Azure, Salesforce.com, Google Cloud, and Oracle) captured more than one third of the worldwide total and growing 35 percent.
The public cloud services market has more than doubled and the combined spending on IaaS and PaaS has nearly tripled since 2016. Enterprise CIOs rely on cloud infrastructure and platforms for application deployment for enterprise IT internal applications as well as SaaS and digital application delivery.
IDC expects spending on IaaS and PaaS to continue growing at a higher rate than the overall cloud market over the next several years, said Deepak Mohan, research director, Cloud Infrastructure Services at IDC.
Cost optimization and business resilience are the top drivers of IT investment decisions and IaaS offerings are designed to enable both. The Covid-19 disruption has accelerated cloud adoption with both traditional enterprise IT organizations and digital service providers increasing use of IaaS for their technology platforms.
SaaS applications is the largest segment of public cloud spending with revenues of more than $122 billion in 2019, said Frank Della Rosa, research director, SaaS and Cloud Software at IDC.
