IBM’s statements regarding its plans, directions, and intent
are subject to change or withdrawal without notice at IBM’s
sole discretion.
Information regarding potential future products is intended to
outline our general product direction and it should not be relied
on in making a purchasing decision.
The information mentioned regarding potential future products is
not a commitment, promise, or legal obligation to deliver
any material, code or functionality. Information about potential
future products may not be incorporated into any contract.
The development, release, and timing of any future features
or functionality described for our products remains at our sole
discretion.
Performance is based on measurements and projections
using standard IBM benchmarks in a controlled environment. The
actual throughput or performance that any user will
experience will vary depending upon many factors, including
considerations such as the amount of multiprogramming in
the user’s job stream, the I/O configuration, the storage
configuration, and the workload processed. Therefore, no
assurance can be given that an individual user will achieve results
similar to those stated here.

Agenda
• MicroProfile
• Java EE 7 (and 8)
• Relationship to WebSphere Liberty

What is MicroProfile?
• https://www.eclipse.org/microprofile
http://microprofile.io/
• Optimizing Enterprise Java for a Microservices
Architecture
• Complements Java EE – not a replacement for
Java EE
5

Background / Introduction
• Goal: To optimize the Enterprise Java mission for
microservice-based architectures and applications that are
portable across multiple runtimes.
• Started as a discussion among community leaders at
Devoxx UK in early 2016. Announced a significant
milestone of MicroProfile 1.0 at JavaOne 2016, with several
vendors ready with production-ready implementations.
• End game is to provide an ”incubation” environment for
innovative technologies in the area of microservices and
Enterprise Java, and eventually submit these technologies
to an appropriate standards body, such as the JCP.

Eclipse MicroProfile
• https://projects.eclipse.org/projects/technology.microprofile
https://www.eclipse.org/microprofile
– Dec 2016 – Eclipse MicroProfile Project proposal accepted; project created
– Initial contributions and contributors based on 2016 microprofile.io
collaboration
– Project leads – Kevin Sutter (IBM) and John Clingan (Red Hat)
• Why Eclipse?
– Provides existing collaboration infrastructure and governance agreeable to
microprofile.io members
– Eclipse is a solid foundation with a proven track record, especially in the Java
community.
– Microservices is a new project idea for Eclipse, so we can grow together
• License
– Apache License, v 2.0

Google Groups
• We use Google Groups for our technical discussions
and topics related to MicroProfile
– https://groups.google.com/forum/#!forum/microprofile
• Some key discussions…
– Process Evolution
– Fault Tolerance and Circuit Breakers
– Config API
– Health Check
– Messaging
– Many others…

Code Repositories
• https://github.com/eclipse/microprofile
– MicroProfile — Top-level repo used to collect Microprofile-related
information
MicroProfile Conference App — "Architectural Application" to
demonstrate MicroProfile on a variety of vendors
MicroProfile Samples — Simple sample application to demonstrate
MicroProfile capabilities
MicroProfile Config — Proposal for MicroProfile application
configuration
MicroProfile Evolution Process — Process for developing new features
for MicroProfile (under construction)
• https://github.com/microprofile
– Original github repo for microprofile.io
– Will continue to exist for maintaining microprofile.io site
Jan 2017 10

Sample Architecture
• Evolving Sample Application
– Started at JavaOne, continues to evolve as features are further defined
and refined
– https://github.com/eclipse/microprofile-conference
• Conference application
– Scheduling, Sessions, Speakers, Voting – all individual microservices
– Wrapped by a simple web application
• Individual or Combined execution
– Each microservice could run on a separate vendor app server instance
– Or, they could all run together on a single vendor app server instance
Jan 2017 11

Roadmap 2017
• MicroProfile 1.x
– Small, iterative timely releases
• Innovate, solidify, release, and repeat
– Community Defined
• MicroProfile 1.1 (1H2017)
– MicroProfile Configuration API
– MicroProfile Health Check API
– MicroProfile JWT Token Definition
– MicroProfile Fault Tolerance
• MicroProfile 1.2 (2H2017?)
– Content still being defined
