Swagger/OpenAPI for Enterprise Java microservices

On June 13, 2017, SmartBear joined the Eclipse MicroProfile project, an open source community specification for Enterprise Java microservices.  As someone interested in microservices, why is this news important?

Microservices and microservice architectures have been in vogue now for a couple of years and IT organizations are rushing to implement (or re-factor) their applications using these new ways of architecting and developing solutions because they are digital transformation enablers (together with CI/CD and containers, among others) that allow them to deliver solutions to the business at faster speeds than ever before. In addition, Java is still ranked as #1 or #2 in programming language use and Enterprise Java, in the form of Java EE specification and implementation, has been used to implement enterprise-grade applications for many years by developers, who can now apply their vast Enterprise Java experience to the implementation of microservices.  The Eclipse MicroProfile open source project fulfills the need in the market for a specification for microservices for Enterprise Java that can mature and evolve commensurately with digital business requirements. Eclipse MicroProfile, as a specification for Enterprise Java microservices, leverages some of Java EE, such as CDI, JAX-RS, JSON-P (no need to recreate the wheel), and adds new APIs1 (config, fault tolerance, security, health check, metrics, etc.) for a complete specification to implement enterprise-grade microservices in Java.

As microservices are leveraged across business applications, consumed across organizational/departmental boundaries, or offered for external consumption (outside the firewall), their management can become unwieldy. Microservices enabling technologies, such as Red Hat OpenShift Container Platform, provide an integrated registry (OpenShift Container Platform can integrate with external registries as well) that ameliorates this situation.  Another management option for microservices is an API management solution. The only entry/exit point in/out of a microservice is its API and an API management solution can manage APIs by applying policies (security, management, throttling, load balancing, etc.) to them, keeping track of them in an internal catalog and giving insight into their usage.  This is why there is a strong synergy between API Management and microservices.

SmartBear Software, the company behind the popular Swagger/OpenAPI framework for defining and creating RESTful APIs, has a long history open source API testing and development tools. There are many REST API description languages in the market, such as RAML, WADL, API Blueprint, WSDL 2.0, but Swagger/OpenAPI is widely recognized as the most popular open source framework for defining and creating RESTful APIs and has become the market de-facto standard, which means that any successful API-related solution must be either based in or provide support via translation to Swagger. As an example, a very successful API management solution is Red Hat 3scale, which supports Swagger/OpenAPI.

The success of any new technology hinges a lot on the ecosystem that surrounds it (or that it is part of).  If it is diverse and rich in options then the technology will thrive and adoption will follow. By definition, microservices and microservices architecture encompass a large ecosystem of programming languages (they are language and technology agnostic, in fact), such as Java, Java EE, Go, PHP, Python, and platforms, such as Red Hat JBoss Enterprise Application Platform and Red Hat OpenShift Application Runtimes (RHOAR). However, a variety of microservices-enabling open source technologies have also come about in recent years, like WildFly Swarm, Vert.x, Node.js, OpenAPI, MicroProfile, Istio. So, the microservices ecosystem is growing and will continue to grow as businesses continue their digital transformation.

As mentioned above, there is a strong synergy and relationship between API management and microservices and SmartBear joining MicroProfile is bringing OpenAPI, the most popular REST API description language, into the MicroProfile ecosystem.

New Open Source Project for Agile Integration in Low Code Environments

At Red Hat Summit this week, Paul Cormier, executive vice president and president, Products and Technologies, demonstrated three stages of application modernization:

  1. rehosting / refactoring a monolithic app
  2. extending that app with OpenShift.io
  3. demoing how to manage applications and services in an integration platform as a service (iPaaS)

The iPaaS demonstration was the first public view of a new open source project focusing on low code integration capabilities on OpenShift.  The new project is available in open source as http://syndesis.io, and community members are encouraged to become involved in the project over the next several milestones.  

iPaaS provides a low code capability that supports non-technical users, that can quickly build integrations between common systems and data, but which is also built upon technology that supports full scale, mission critical enterprise integration projects.

What It Is

  • Syndesis provides an iPaaS implementation built on  Red Hat JBoss Fuse and Red Hat OpenShift technologies
  • The easy-to-use cloud-native integration toolset allows a low-code web interface to:
    • Create, connect and manage integrations quickly (no installation needed)
    • Create and connect APIs (using web based tooling)
    • Point and click tools to build, test & deploy integrations
    • Pre-built connectors to connect multiple apps and services
    • Build simple to complex connections
  • Built on Red Hat JBoss Fuse and Red Hat OpenShift, allowing the same underlying technology proven for large scale or sophisticated deployments

Why This Is Different

  • Syndesis is a curation of multiple open source communities, focusing on providing a fully open source iPaaS, low-code environment based on Apache Camel, JBoss Fuse, etc.
  • Focused on supporting the agile integration methodology
  • Fully integrated with Kubernetes and Linux containers (Docker/Moby)
  • Enables ubiquitous integrations: API-based hybrid integrations across on-premise, private or public cloud
  • Can be extended  with additional capabilities like Red Hat 3scale API Management, Red Hat JBoss BPM Suite, Red Hat JBoss BRMS and Red Hat JBoss Data Grid

What To Do Next

Announcing: Red Hat Single Sign-On 7.1 GA Is Available

We are proud to announce general availability of Red Hat Single Sign-On 7.1 (RH-SSO). RH-SSO is a standards-based, out-of-the-box authentication, web single sign-on, and authorization service, which mediates between your enterprise user directory or third-party identity provider for identity information and your applications via standards-based tokens.

Documentation and downloads are available in the Customer Portal. RPM packages are available for Red Hat Enterprise Linux 6 and 7 systems through Red Hat Subscription Management.

Features and Highlights

OPENID CONNECT CERTIFICATION

The Keycloak version included in Red Hat Single Sign-On (RH-SSO) 7.1 conforms to the 5 OpenID Connect profiles: Basic, Implicit, Hybrid, Config, and Dynamic. Certification was achieved in Keycloak v2.3 (http://openid.net/certification/). Future RH-SSO versions will remain compatible with these profiles, unless documented otherwise.

 

CLIENT ADAPTER FOR RED HAT JBOSS FUSE

RH-SSO 7.1 features a new client adapter for Red Hat JBoss Fuse, which enables securing web application archives (WARs), servlets, Apache routes and Apache CXF endpoints deployed on JBoss Fuse, in both Apache Karaf and Red Hat JBoss Enterprise Application Platform (JBoss EAP).

 

NODE.JS CLIENT ADAPTER

RH-SSO 7.1 includes a new Node.js client adapter, which enables use of RH-SSO 7.1 Server for authentication and web single sign-on for Node.js applications.

 

EXTERNALIZED AUTHORIZATION SERVICE

RH-SSO 7.1 introduces a new authorization service feature-set, based on the User Managed Access specification. This enables RH-SSO 7.1 Server to act as a policy administration point, policy decision point, or policy information point, separating the authorization logic from the application.

 

USER STORAGE SPI

RH-SSO 7.1 features a new user storage SPI that you can use to implement your own custom user storage federation provider, such as a relational or NoSQL database, to enable federation of users from any user store.

 

SSSD INTEGRATION

RH-SSO 7.1 adds an integration with System Security Services Daemon (SSSD) in Red Hat Enterprise Linux (RHEL) 7.3. This enables use of SSSD as a user federation provider in front of a Microsoft Active Directory forest.

 

CLIENT REGISTRATION CLI

RH SSO 7.1 introduces a command-line interface (CLI) for developers to register client applications on RH-SSO Server.

 

Five Links: Amazon Broke the World Edition

Happy Friday, everyone.

In the most cruelest of cuts, Amazon killed the internet for several hours on Tuesday. The one upside is that it was more real-life evidence that some IT intern would probably fat-finger a Skynet password and stop Judgment Day before it ever begins. In honor of those lost, dark hours, this week’s post is about the times that the internet and technology have let us down. Nightmare fuel, it is.

Five Links: I Can See the Future Edition

Happy Friday, everyone! And happy new year.

Full disclosure: I cannot, in fact, see the future. I need to emphasize that. But this is the time of year when people take a few moments to reflect on where they’ve been and where the year could take technology. We had some nice stuff on some of my Red Hat sister blogs — 3scale has a review of API management trends and the Services Speaks Blog had a nice link round-up.

I look at a couple of traditional listicles on trends, but there are some posts and  news coming out that I think hint at larger changes, and that interests me.

Ivan Cardona, owner, Opticca

We’ve been been deploying middleware, SOA, and BPM platforms from the major providers for the past eight years. We’ve recently made a large investment In Red Hat’s JBoss solutions because our customers’ feedback led us to conclude open source is now a real option. Our customers experienced tremendous success deploying services and business processes leveraging these platforms. The challenge they face is the solutions are too expensive to scale further and/or many find the platform overhead is too heavy. Red Hat’s Jboss solutions directly address those two concerns. For this reason we are very bullish on Red Hat’s ability to gain a substantial portion of the middleware, BPM, container, and micro services market.

Upcoming Webinar: Data Management in a World of Big – and Fast – Data

William Burns (senior engineer) and Divya Mehra (middleware product marketing manager for Red Hat) will be conducting a webinar about how to choose the right data storage and management platform for different projects and design scenarios.

Not every project has the same data streams or the same requirements on how to access and use data. The Internet of Things, cloud applications, mobile applications, and even social platforms all rely on “big data” — but while all of those collect, process, and access massive amounts of data, they don’t do it in the same ways. This webinar looks first at the different potential data streams and uses for that data, depending on the type of project you have, and then it looks at different ways of using Red Hat JBoss Data Grid to store and manage that data: in a distributed cache, an in-memory NoSQL database, an event broker, and a big data/IoT store.

Registration is open. The webinar is June 21 at 11:00am Eastern Time (US).
