Enterprise Application Development Is Changing

3

Rapid Changes Over Past Few Years

4

Microservices

Apps divided into many small pieces

Distributed Computing

Many data centers, AZs, regions, etc.

Polyglot Java leads but use of others increasing

New Technology

Docker, Cloud, DevOps, etc.

Driven by increasing business needs

How Do We Make This Easier?

It’s Confusing!

Too many choices.... Which components? Overall architecture? Standards? Vendor commitment?


Proposed Enhancements for Java Enterprise Edition

• New AppDev style for Cloud and Microservices

• Build on proven technologies

• Comprehensive

– Programming Model, Packaging, Portability

• Standards-based

– This is a proposal only

– Will work with the community and follow the JCP process

10


Designed for Agility and Scalability with Security • Programming model

– Extend for reactive programming

– Unified event model, event messaging API

– JAX-RS, HTTP/2, Lambda, JSON-B, …

• Eventual consistency

– Automatically event out changes to observed data structures

• Key value/document store

– Persistence and query interface for Key Value and Document DB

• Security

– Secret management

– OAuth/OpenID support

Location Transparency and Resiliency

• Configuration

– Separate service packaging and configuration

– API for external configuration

• State

– API for external state

• Resiliency – Circuit breakers

– Resilient commands

– Standardized health reporting

Packaging for Simplicity • Packaging – Docker model

– Package applications, runtimes into containers

– Separate service package and configuration

– Standalone immutable executable binary

– Multi-artifact archives, leveraging Java 9

• Serverless – New spec – interfaces, packaging format, manifest

– Ephemeral instantiation

• Multitenancy – Increased density

– Tenant-aware routing and deployment
