The Container Native Challenge

Today, customers face a difficult decision when selecting a container-native application stack.  Either they choose from a mind-boggling menu of non-integrated, discrete and proprietary components from their favorite cloud provider – thus signing up for layers of DIY integration and administration – and slowly getting locked into that cloud vendor drip-by-drip.  Alternatively, many enterprises venture down a second path and select an opinionated application development stack – which looks “open” at first glance but in reality, consists of closed, forked, and proprietary components – well-integrated, yes, but far from open and cloud neutral.   More lock-in?  Absolutely.

So, what if you could combine an integrated developer experience with an open, cloud-neutral application stack built to avoid cloud lock-in?

Announcing Oracle’s Container Native Application Development Platform

The Container Native Application Development team today at Oracle OpenWorld 2017 announced the Oracle Container Native Application Development Platform – bringing together three new services - managed Kubernetes, CI/CD, and private registry services together in a frictionless, integrated developer experience.  The goal?  To provide a complete and enterprise-grade suite of cloud services to build, deploy, and operate container-native microservices and serverless applications.   Developers, as they rapidly adopt container-native technologies for new cloud-native apps and for migrating traditional apps, are becoming increasingly concerned about being locked-in by their cloud vendors and their application development platform vendors.  Moreover, they are seeking the nirvana of the true hybrid cloud, using the same stack in the cloud - any cloud - as they run on premise.

Directly addressing this need, the Oracle Container Native Application Development Platform includes a new managed Kubernetes service - Oracle Container Engine - to create and manage Kubernetes clusters for secure, high-performance, high-availability container deployment.  Secondly, a new private Oracle Container Registry Service for storing and sharing container images across multiple deployments. And finally, a new, full container lifecycle management CI/CD service Oracle Container Pipelines, based upon the Wercker acquisition, for continuous integration and delivery of microservice applications. 

Why should you care? Because unlike other cloud providers and enterprise appdev stack vendors, the Container Native Application Development Platform provides an open, integrated container developer experience as a fully-managed, high-availability service on top of an enterprise-grade cloud (bare metal & secure).  A free community edition of Wercker and early adopter access to the full Oracle Container Native Application Development Platform are available at wercker.com.

Meet Fn: An Open Source Serverless Solution

So as if that weren’t enough, we today open sourced Fn, a serverless developer platform project  fnproject.io. Developers using Oracle Cloud Platform, their laptop, or any cloud, can now build and run applications by just writing code without provisioning, scaling or managing any servers – this is all taken care of transparently by the cloud.  This allows them to focus on delivering value and new services instead of managing servers, clusters, and infrastructure. As Fn is an open-source project, it can also be run locally on a developer’s laptop and across multiple clouds, further reducing risk of vendor lock-in. 

Fn consists of three components: (1) the Fn Platform (Fn Server and CLI); (2) Fn Java FDK (Function Development Kit) which brings a first-class function development experience to Java developers including a comprehensive JUnit test harness (JUnit is a unit test harness for Java); and (3) Fn Flow for orchestrating functions directly in code. Fn Flow enables function orchestration for higher level workflows for sequencing, chaining, fanin/fanout, but directly and natively in the developer’s code versus relying on a console.  We will have initial support for Java with additional language bindings coming soon.

How is Fn different? Because it’s open (cloud neutral with no lock-in), can run locally, is container native, and provides polyglot language support (including Java, Go, Ruby, Python, PHP, Rust, .NET Core, and Node.js with AWS Lambda compatibility). We believe serverless will eventually lead to a new, more efficient cloud development and economic model.  Think about it - virtualization disintermediated physical servers, containers are disintermediating virtualization, so how soon until serverless disintermediates containers?  In the end, it’s all about raising the abstraction level so that developers never think about servers, VM’s, and other IaaS components, giving everybody better utilization by using less resources with faster product delivery and increased agility.  But it must follow the developer mandate: open, community-driven, and cloud-neutral.  And that’s why we introduced Fn.

Java 9: Driving the Build–Deploy–Operate Cloud Loop

DevOps and SRE patterns consistently look for automation and culture to create a repeatable application lifecycle of build, deploy, and operate. The latest Java SE 9 release, announced September 21, 2017 and highlighted at the JavaOne 2017 conference, includes more than 150 new features that help drive new Cloud Native development in this model.  Java SE 9 (JDK 9) is a production-ready implementation of the Java SE 9 Platform Specification, which was recently approved together with Java EE 8 in the Java Community Process (JCP).  Java continues to fuel cloud development in a big way - judging by the latest metrics.  The numbers are staggering: 

- #1 Developer Choice for the Cloud
- #1 Programming Language
- #1 Development Platform in the Cloud

Supported by these metrics:

- 12 Million Developers Run Java
- 21 Billion Cloud Connected Java Virtual Machines
- 38 Billion Active Java Virtual Machines
- 1 Billion Downloads Per Year

So, what’s new in Java 9?  Too much to list here, but a good way to summarize it is to look through a DevOps lens as the Java community continues to improve Java and its application in cloud native application development.  Highly effective DevOps teams are seeking to improve their Build-Deploy-Operate loop to build better code, deploy faster and more often, and recover faster from failures – and new Java 9 features are leading the way:

- Build Smarter
  -- JShell to easily explore APIs and try out language features
  -- Improved Javadoc to learn new APIs
  -- New & improved APIs including Process, StackWalker, VarHandle, Flow, CompletableFuture

- Deploy Faster
  -- New module system - Project Jigsaw
  -- Build lightweight Java apps quickly and easily
  -- Bundle just those parts of the JDK that you need
  -- Efficiently deploy apps to the cloud
  -- Modular Java runtime size makes Docker images smaller & Kubernetes orchestration more efficient

- Operate Securely
  -- More scalability and improved security
  -- Better performance management
  -- Java Flight Recorder released to OpenJDK for improved monitoring and diagnostics

To learn more and try out some new sample apps check out wercker.com/java.  And speaking of open source, agility, and velocity, Oracle is moving to a 6-month release cadence for Java SE 9, and will also be providing OpenJDK builds under the General Public License (GPL).  Cool - more open, more better, more often. Also, we will be contributing previously commercial features to OpenJDK such as Java Flight Recorder in Oracle JDK targeting alignment of Oracle JDK and OpenJDK.

Cloud Foundry on Oracle Cloud

For Cloud Foundry developers, we’ve released an Open Service Broker implementation that integrates Oracle Cloud Platform Services with Cloud Foundry so you can now build directly on the Cloud Foundry framework on Oracle Cloud.  Also, we’ve open sourced the BOSH Cloud Provider Interface, so developers can deploy Cloud Foundry workloads directly on Oracle Cloud Infrastructure, a capability targeted for general availability for later this year.

Beating the Open Source Drum

As a container native group, we’re committed to the open source community and these announcements showcase that commitment. The Oracle Container Native Application Development Platform is yet another step in our journey to deliver an open, cloud neutral and frictionless experience for building cloud-native as well as conventional enterprise applications. Over the course of this spring and summer, Oracle has shown continued commitment to open-source standards by joining the Container Native Computing Foundation, dedicating engineering resources to the Kubernetes project, open-sourcing several container utilities and making its flagship databases and developer tools available in the Docker Store marketplace.
