In the recent Break New Ground paper, 10 Predictions for Developers in 2019, openness was cited as a key factor that determines developers' choice. Developers want a choice of languages, databases, and compute shapes, among other things. This allows them to focus on what they care about – creating – without ops concerns or lock in. In this post, we outline the top ways that Oracle is delivering a truly open cloud. 


Oracle Cloud’s Autonomous Database, which is built on top of Oracle Database, conforms to open standards, including ISO SQL:2016, JDBC, Python PEP 249, ODBC, and many more. Autonomous Database is a multi-model database and supports relational as well as non-relational data, such as JSON, Graph, Spatial, XML, Key/Value, Text, amongst others. Because Oracle Autonomous Database is built on Oracle Database technology, customers can “lift and shift” workloads from/to other Oracle Database environments, including those running on third-party clouds and on-premises infrastructure. This flexibility makes Oracle Autonomous Database a truly open cloud service compared to other database cloud services in the market. Steve Daheb from Oracle Cloud Platform provides more information in this Q&A.

In addition, Oracle MySQL continues to be the world's most popular open source database (source code) and is available in Community and Enterprise editions. MySQL implements standards such as ANSI/ISO SQL, ODBC, JDBC and ECMA. MySQL can be deployed on-premises, on Oracle Cloud, and on other clouds.

Integration Cloud

With Oracle Data Integration Platform, you can access numerous Oracle and non-Oracle sources and targets to integrate databases with applications. For example, you can use MySQL databases on a third-party cloud as a source for Oracle apps, such as ERP, HCM, CX, NetSuite, and JD Edwards. In addition, Integration Cloud allows you to integrate Oracle Big Data Cloud, Hortonworks Data Platform, or Cloudera Enterprise Hub with a variety of sources: Hadoop, NoSQL, or Oracle Database.

You can also connect apps on Oracle Cloud with third-party apps. Consider a Quote to Order system. When a customer accepts a quote, the salesperson can update it in the CRM system, leverage Oracle’s predefined integration flows, with Oracle ERP Cloud, and turn the quote into an order.  


Java is one of the top programming languages on Github (Oracle Code One 2018 keynote), with over 12 million developers in the community. All development for Java happens in OpenJDK and all design and code changes are visible to the community. Therefore, the evolution of ongoing projects and features is transparent. Oracle has been talking with developers who are and aren’t using Java to ensure that Java remains open and free, while making enhancements to OpenJDK. In 2018, Oracle open sourced all remaining closed source features: Application Class Data Sharing, Project ZGC, Flight Recorder and Mission Control. In addition, Oracle delivers binaries that are pure OpenJDK code, under the GPL, giving developers freedom to distribute them with frameworks and applications.

Oracle Cloud Native Services, including Oracle Container Engine for Kubernetes

Cloud Native Services include the Oracle Container Engine for Kubernetes and Oracle Cloud Infrastructure Registry. Container Engine is based off unmodified Kubernetes codebase and clusters can support bare-metal nodes, virtual machines or heterogeneous BM/VM environments. Oracle’s Registry is based off open Docker v2 standards, allowing you to use the same Docker commands to interact with it as you would with Docker Hub. Container images can be used on-premises and on Container Engine giving you portability. It can also interoperate with third-party registries and Oracle Cloud Infrastructure Registry with third-party Kubernetes environments. In addition Oracle Functions is based off the open source Fn Project. Code written for Oracle Functions will therefore run not only on Oracle Cloud, but with Fn clusters on third-party clouds and on-premises environments as well.

Oracle offers the same cloud native capabilities as part of Oracle Linux Cloud Native Environment. This is a curated set of open source Cloud Native Computing Foundation (CNCF) projects that can be easily deployed, have been tested for interoperability, and for which enterprise-grade support is offered. With Oracle’s Cloud Native Framework, users can run cloud native applications in the Oracle Cloud and on-premises, in an open hybrid cloud and multi-cloud architecture.

Oracle Linux Operating System

Oracle Linux, which is included with Oracle Cloud subscriptions at no additional cost, is a proven, open source operating system (OS) that is optimized for performance, scalability, reliability, and security. It powers everything in the Oracle Cloud – Applications and Infrastructure services. Oracle extensively tests and validates Oracle Linux on Oracle Cloud Infrastructure, and continually delivers innovative new features to enhance the experience in Oracle Cloud.

Oracle VM VirtualBox

Oracle VM VirtualBox is the world’s most popular, open source, cross-platform virtualization product. It lets you run multiple operating systems on Mac OS, Windows, Linux, or Oracle Solaris. Oracle VM VirtualBox is ideal for testing, developing, demonstrating, and deploying solutions across multiple platforms on one machine. It supports exporting of virtual machines to Oracle Cloud Infrastructure and enables them to run on the cloud. This functionality facilitates the experience of using VirtualBox as the development platform for the cloud.

Identity Cloud Services

Oracle Identity Cloud Service provides 100% API coverage of all product capabilities for rich integration with custom applications. It allows compliance with open standards such as SCIM, REST, OAuth and OpenID Connect for easy application integrations. Customers can easily consume these APIs in their applications to take advantage of identity management capabilities.

Oracle Identity Cloud Service seamlessly interoperates with on-premises identities in Active Directory to provide Single Sign On between Cloud and On-Premises applications. Through its Identity Bridge component, Identity Cloud can synchronize all the identities and groups from Active Directory into its own identity store in the cloud. This allows organizations to take advantage of their existing investment in Active Directory. And, they can extend their services to Oracle Cloud and external SaaS applications.

Oracle Blockchain Platform

Oracle Blockchain Platform is built on open source Hyperledger Fabric making it interoperable with non-Oracle Hyperledger Fabric instances deployed in your data center or in third-party clouds. In addition, the platform uses REST APIs for plug-n-play integration with Oracle SaaS and on-premises apps such as NetSuite ERP, Flexcube core banking, Open Banking API Platform, among others.

Oracle Mobile Hub (Mobile Backend as a Service – MBaaS)

Oracle Mobile Hub is an open and flexible platform for mobile app development. With Mobile Hub, you can:

  • Develop apps for any mobile client: iOS or Android based phones

  • Connect to any backend via a standard RESTful interfaces and SOAP web services

  • Support both native mobile apps and hybrid apps. For example, you can develop with Swift or Objective C for native iOS apps, Java for native Android apps, and JavaScript for Hybrid mobile apps

In addition, Oracle Visual Builder (VB) is a cloud-based software development Platform as a Service (PaaS) and a hosted environment for your application development infrastructure. It provides an open source, standards-based solution to develop, collaborate on, and deploy applications within Oracle Cloud that provides an easy way to create and host web and mobile applications in a secure cloud environment.


In choosing a cloud vendor, openness can provide a significant advantage, allowing you to choose amongst languages, databases, hardware, clouds, and on-premises infrastructure.  With a free trial on Oracle Cloud, you can experience the benefits of these open technologies – no strings attached.
