Characteristics of Cloud Native Applications • Modern – born in the cloud (era) • Emphasis on interaction (and decoupling) points: • Between custom components: APIs, Events / message format • From custom to PaaS Services: Service APIs, Formats and Protocols • Less emphasis on [and insulation from?] implementation of PaaS (platform) services • Key are industry standard APIs that are implemented by many different services • Custom code in small, simple units • No explicit Infrastructure (serverless, software defined) & managed Platform components • Stateless and Dynamically Scalable (Elastic) – expand and contract • Pay per Use • Automation – no hands on ACC and Production (speed, repeatability, dynamic adjustment) • Infrastructure/Platform as Code & Application CI/CD [pipelines] UKOUG 2021 Spring Tech Summit| Oracle Cloud Native Application Development

Introducing Oracle Cloud Infrastructure UKOUG 2021 Spring Tech Summit| Oracle Cloud Native Application Development
Oracle Cloud Gen2 • First generation is now called Classic Cloud • Mainly On Premises software, running in Oracle’s data centers – with some (small) degree of operational management (mainly provisioning and patching) • Not Cloud Native • Gen2 • (largely) Designed from the ground up for the cloud • Applying lessons learned – from classic cloud as well as AWS and Azure • Some focused acquisitions (Dyn, Corente, Palerra, Wercker, DataScience.com) UKOUG 2021 Spring Tech Summit| Oracle Cloud Native Application Development
Oracle Cloud Infrastructure • Generation 2 Cloud • Main themes: • Competitive Pricing • Secure by Design • Open • Enterprise (Technology) • Trials – 30 days, $300 credits • An always-free tier • With Autonomous Database and Autonomous Data Warehouse UKOUG 2021 Spring Tech Summit| Oracle Cloud Native Application Development
