modern JavaScript UI
• Allow coders and low-code
developers to work in harmony
• Reduce IT backlog and build
solutions faster

Oracle Java Extension Toolkit (JET)
Oracle JET is targeted at JavaScript
developers working on client-side
applications. It's a collection of open
source JavaScript libraries along with
a set of Oracle contributed JavaScript
libraries that make it as simple and
efficient as possible to build web and
mobile applications that consume and
interact with Oracle products and
services, specifically Oracle Cloud
Services.

for code snippets (next to PL/SQL)
• Based on Graal VM Database MLE
• Try out at apexea.oracle.com
• APEX in Database Application Containers – one APEX base for multiple PDBs

APEX other things
• Regression Testing
• Record all requests at ORDS
• Replay at any moment
• Create tests by simply using the application
• Metrics
• Technical – which pages are slow/when are spike in traffic
• Functional – which features are used/are problematic
• Expose through Prometheus Exporter
• Use of Flashback
• Source code control

VBCS vs APEX
• PL/SQL
• And now with Graal VM/MLE also
JavaScript & Python
• Database oriented
• One phyical tier
• Can be installed on any Oracle Database
instance, anywhere
• Could be 18c XE
APEX
• Javascript
• Client oriented
• Only runnable on Visual Builder Cloud
• In the future also portable
(when running only against remote REST)
• Any backend (REST API)
• Mobile support
• Native on device
• PWA
• Used by Oracle SaaS teams to build new
modules
Visual Builder Cloud

Eclipse Che – browser based IDE
• Runs as Docker Container
• Local or Server or Cloud based
• Single or Multi user

Java EE at Oracle: WebLogic
• WebLogic Release Schedule
• 12.2.1
• 12.2.1.2
• 12.2.1.3 (PS3)
• 19.1 (PS4)
• 19.2
• WebLogic 19.2 will have Java EE 8 support
• And work with JDK 8 and JDK 11

Application Container Cloud
• Maintenance Mode as is
• Current offering is convenient – but can be a bit expensive when running
many ACC instances
• And it does not support bring your own Docker image
• Future is probably based on Kubernetes on OCI (aka OKE)
• In that case: you only pay for OCI resources
• And the Application Container Cloud console, PSM, format are a free
convenience

Continuous Integration, Continuous Delivery, and DevOps
– Continuous Integration (CI) is a key component of Agile Development practices. It requires developers to
integrate their individual work with one another as early as possible in the software development life cycle.
This exposes integration issues and conflicts on a regular basis.
– Continuous Delivery (CD) provides tools and best-of-breed practices to deliver quality software quickly. At
the end of every CI build, the software is delivered to the QA team for testing and then to the operations
team (the Ops in DevOps) for delivery to production environments.

DevOps Life Cycle
– The DevOps lifecycle is a continuous cycle of planning, coding, building, testing, releasing,
deploying, operating, and monitoring.
– Rather than ending when the code is “live,” the cycle continues by monitoring the current
release and working toward the next (and the next…).

Infrastructure as Code
• CI/CD not only for custom developed software
• Also for platform and infrastructure provisioning and configuration
• Container build files
• Kubernetes resource manipulation yaml-files
• Cloud infrastructure management scripts
• Ideally code describes the desired end state
• Not the commands to execute
• Oracle Cloud Infrastructure standardizes on Terraform
• Configurable scripts for creating Cloud network resources,
spinning up VMs, provisioning Databases, assigning roles and
privileges, starting/scaling/stopping services
• Note: shell scripts using the OCI CLI are an alternative

Deployment Environments

CI/CD with Serverless Fn

Kubernetes changes the game for DevOps (and CI/CD)
• Uniform deployment platform: Kubernetes cluster
• parity across environments
• Uniform deployment artifact: container
• Automated Rolling Upgrade facility
• Leveraging standard facilities
• Container Registry
• Kubernetes APIs
• Custom Operator
• Using generally adopted tools
• Helm/Tiller
• Prometheus (monitoring metrics) & Grafana

Kubeapps

Jenkins and Kubernetes
• Jenkins can run on Kubernetes itself
• Install using Kubeapps Helm Chart
• Can leverage Kubernetes
• To run build servers (in dynamically spun up Pods)
• As deployment target for newly built artifacts
• Jenkins X: opinionated
• Preconfigured according to CI/CD best practice
• Implements GitOps
• Preview Environment for Pull Requests
