Oracle Cloud Infrastructure - A Guide to Building Cloud Native Applications by J

Description: Oracle Cloud Infrastructure - A Guide to Building Cloud Native Applications by Jeevan Joseph, Adao Junior, Mickey Boxell Oracle Cloud Infrastructure: A Guide to Building Cloud Native Applications Cloud native development is a modern approach to designing, building, deploying, and managing applications. This approach takes advantage of the benefits of utility computing from providers, such as Oracle Cloud Infrastructure (OCI), and emphasizes automation, elasticity, and resilience. OCI is a next-generation cloud designed to run any application faster and more securely for less. It includes the tools used to build new cloud native applications and to run existing enterprise applications without rearchitecting them. Whether you are new to the cloud or just new to OCI, this book provides an overview of the OCI services needed to build cloud native applications. You will learn OCI concepts and terminologyHow to manage Infrastructure as Code using modern tools and platformsOCIs breadth of cloud native servicesHow to operate the managed Kubernetes service (Container Engine for Kubernetes) at scaleHow to configure a cluster for advanced use cases, and use specialized hardware capabilitiesHow to use cloud native application deployment platforms and observability toolsHow to secure applications, data, and the underlying infrastructure using open-source and OCI native security tools and processes The culmination of the book is an open-source sample application composed of microservices that incorporates the tools and concepts shared throughout the book and is available on GitHub.
