PRICE OPEN SOURCE
STRATEGY
CLOUD MIGRATION &
REPLATFORMING
Oracle is known for its high software
licensing costs.
• Many features now commoditized or
delivered more economically
• Penalizing contract terms and agreements
amplify pain
Gartner cites that 70% of new applications
are being built on open source databases.
• Secure greater control & lower costs
• Reduce Oracle lock-in risk
• Innovate more quickly
Deployment and delivery on the cloud and
containers is a critical element of
enterprise IT and technology missions.
• Moving to the cloud allows provides
enterprises to consider Oracle alternatives
• Coupled tightly with open source
strategies
