Converting ADLs to implement end to end JSON in SOA Suite 12.2.1 -PART I by Luis Augusto Weir

clip_image002

 

There is no doubt that web [Rest] APIs have become extremely popular and its usage has gone well beyond just building APIs in support of mobile apps. We can see the adoption of resource-oriented architectures (ROA) by probably all SaaS vendors who provide out-of-the-box APIs as the means to connect and interact with their cloud applications. Take for example the Oracle Cloud. To discover and consume publicly available Oracle SaaS APIs, all one need to do is browse the Oracle API Catalog Cloud Service (which is publicly accessible) and just select the Swagger definition for any given API.

But (as you probably already know) the adoption of web APIs hasn’t stopped there.  With the increased popularity of Microservice Architectures , initiatives such as Open Legacy ,  and node.js based frameworks like loopback and sails (to name a few), API-enabling system of records is becoming a lot easier.
This is putting a lot of pressure in software vendors to quickly modernise their integration suites to natively support the technology-stacks and patterns prevalent in these type of architectures. For example, if an organisations mobile application needs to interact with a system of record (on premise or the cloud) that already exposes a web API, the integration stack should be capable of supporting JSON over HTTP end-to-end without having to convert to XML back and forth. Not only is this impractical but introduces more processing burden to the core stack…
Luckily for many Oracle’s customers and Oracle Fusion Middleware / Oracle PaaS practitioners like myself, with the latest release of Oracle SOA Suite (12.2.1) , one of the many new features introduced is the support for handing JSON end-to-end.  I don’t want to understate the importance of this as with such feature it is possible to use BPEL for example to orchestrate several APIs (all in native JSON and also in-memory with the new SOA in-memory feature) and therefore deliver coarse grained business APIs that actually perform.
For me this represents an important milestone for Oracle SOA Suite as it shows the departure from traditional SOA tech-stack and into SOA 2.0 (as I like to call it) as the suite is now better suited to support the adoption of ROA, microservices, IoT, and so on. Having worked with SOA Suite since 10.1.3.1 this is very exiting. Read the complete article here.

API Management Implementation 12c Book Overview by Luis Augusto Weir

 

clip_image002Digital transformation is at the core of every business strategy regardless of what type of business an organisation is in. Companies that embark on a on a digital transformation journey are able to create innovative and disruptive solutions that are capable of delivering a much richer, unified and personalised user experience, at a lower cost. They are able to engage the customer in a seamless fashion through many channels such as mobile apps, responsive websites and social media. Organisations that adopt innovative digital business models gain considerable competitive advantage over those that don’t.
The fundamental driver for digital transformation is the ability to unlock key information assets and business functionality, which is often hidden inside an organisation’s enterprise systems and in SOA based web services which are only internally accessible. To materialise these assets, organisations need to build web based Application Programming Interfaces (APIs) that not only provide standard, lightweight web access to these assets but also do so in a secured and controlled fashion. The lightweight nature and ease of use of these web APIs, ensure that they soon become the main mechanism for accessing information and functionality that is needed to build mobile applications, responsive websites and other cloud based solutions.
API management is the discipline that governs the software development lifecycle of APIs. It defines the tools and processes needed to build, publish and operate APIs including the management of the community of developers around it. Read the complete article here.

A Word About Microservice Architectures and SOA by Luis Augusto Weir

 

clip_image002In this article I will talk about my first conclusions and my point of view regarding Microservice Architectures. As there is still quite a lot of confusion and debate out there on this topic, I will try to describe with my own words what Microservice Architecture is, how does it differ from typical Service Oriented Architectures (SOA) and what design principles and practices governs it.
What is a Microservice Architecture?
In the article http://martinfowler.com/articles/microservices.html written by Fowler and Lewis, Microservice Architecture is described as following::

Microservice architectural style is an approach to developing a single application as a suite of small services, each running in its own process and communicating with lightweight mechanisms, often an HTTP resource API. These services are built around business capabilities and independently deployable by fully automated deployment machinery. There is a bare minimum of centralized management of these services, which may be written in different programming languages and use different data storage technologies

The article overall it’s a fantastic piece of work (really suggest you read it). The way Microservice Architectures it’s defined opens up a few pandora boxes (in a good way I think) which I will talk about subsequently.
First of all, if you are familiar with SOA and it’s guiding principles this will seem very familiar (read for example: http://en.wikipedia.org/wiki/Service-oriented_architecture or http://www.soa-manifesto.org/). Yet, if you noticed the highlighted texts, it’s not quite the same as what we are used to in traditional SOA. The truth is, wether we accept it or not, SOA architectures evolved around the adoption of certain design patterns (such as Enterprise Service Bus (ESB), canonical schemas, centralised contracts, -see http://www.soapatterns.org/ for more) and the use of SOA specific infrastructures to build and deploy services and APIs became the approach of choice (note that the service vs API topic it’s not discussed in this post. For my view on this read http://www.soa4u.co.uk/2013/09/restful-is-also-soa.html).
From my perspective, I would define Microservice Architecture’s as both 1) a design pattern and 2) a discipline for delivering services and APIs. To elaborate further based on my conclusions I can highlight the following guiding principles:

  • Delivering business focused and lightweight services/APIs that are truly design, built, deployed and executed independently of each other (meaning that in terms of infrastructure dependencies, they share very little)
  • Strong focus on people collaboration and communication as the main mechanism in the adoption of best practices and standards rather than common set of strict guidelines and standards that constraint the way services are define, built, deployed and maintained
  • DevOps (config management, deployment automation, CI, Continuous Delivery) as a fundamental building block rather than a value add
  • Scalability should be easy as services are very lightweight and stateless (The same service can run in many servers and DevOps makes the deployment process automatic and easy)
  • Doesn’t encourages the use of monoliths to deploy services (a monolith is for example an application server or an ESB). Services should run almost as demons

One can argue that SOA architectures can also satisfy the listed requirements as SOA it’s really an architecture paradigm that can be realised in different ways. I personally think this myself and I would regard Microservice Architecture as a SOA design pattern, however as per my previous point, comparing it with traditional SOA architecture’s there is a difference.

API Catalog 12c Full Overview by Luis Weir

 

clip_image002Oracle has recently released Oracle Enterprise Repository (OER) 12c and Oracle API Catalog (OAC) 12c.I am particularly exited on the latter as it aims to simplify management of APIs and promises to be able to create catalog of your services and APIs rapidly. Furthermore, although OER 12c maintains the same richness as in OER 11g, this product is targeted to advance users that are in need to address more complex governance requirements whereas OAC it’s a light-weight version of OER however tailored to address specific use cases of API management such as cataloguing, discovering and rating APIs.
This blog is about my first impression when installing, configuring and using Oracle API Catalog. In the blog I provide all steps I followed to achieve these tasks and at the end I provide a summary of my experience and feedback of the product.

Installation Pre-requisites

  • Download Weblogic Server 12.1.3 and OER 12.1.3 software binaries from following link (note that OAC uses same OER installer)

http://www.oracle.com/technetwork/middleware/repository/downloads/index.html

  • You will need an Oracle Database installed (you may also download database from previous link). If you already have an environment with an Oracle Database available you can check supported versions from following link

http://www.oracle.com/technetwork/middleware/ias/downloads/fusion-certification-100350.html

  • Ensure you have installed JDK 7.0 Update 55 or later. You can download it from the following link:

http://www.oracle.com/technetwork/java/javase/downloads/index.html

  • Oracle API Catalog Home Page and Installation Guide:

https://docs.oracle.com/middleware/1213/oac/index.html
https://docs.oracle.com/middleware/1213/oac/install-cat/toc.htm

Installation

Firstly install Oracle Database and Weblogic Server as per instructions.

Then continue with installation of OAC 12c as per following instructions: https://docs.oracle.com/middleware/1213/oac/install-cat/intro.htm#CATIG146

SOA/API developer tool tips by Luis Augusto Weir

 

clip_image001Having been delivering SOA projects for over a decade, I’ve come across many tools some of which I hate and avoid using them (unless a client demands so)  and others that have made my life easier when delivering projects.

The below table is a recollection of tools I have used or come across which  I find useful and recommend SOA/API practitioners to use or at least evaluate. Enjoy 🙂

SDLC Tool Name Description + Links
Project/Scrum Management and Collaboration Jira Jira when used for scrum management is In my opinion is the the best tool I’ve used for managing scrums specially in an offshore / onshore distributed environment. It also has capabilities to manage GIT repositories which makes this an ideal tool for a complete cloud/based agile project with users all over the world.
https://www.atlassian.com/software/jira
Agilo I used this tool some time back successfully in a large onsite SOA project and it worked very well for us. Product has come along way since then and It’s more feature rich than it used to be. It has a 30 day trial.
http://agilosoftware.com/
Trello Very simple, lean and easy to use project/task management and collaboration tool. It’s free for any number of users, can log-in using Google account.
Thanks Darren Atkinson for this tip!
https://trello.com
Furthermore there are some awesome plug-ins to use it for Agile projects:

https://www.burndownfortrello.com/

http://scrumfortrello.com/

Coop App very clean UI supporting features such as share status updates, questions, links, and others.
http://coopapp.com/
PBworks Suite of tools including in-app instant messaging, live notifications of changes to work spaces, live editing of documents, voice collaboration, wiki, and others. Can be used for full collaboration including project management.
http://www.pbworks.com/
Configuration Management GitHub I have been using this tool recently but found it amazing specially because of the GitHub client which is not intrusive to filesystem (like Tortoise and that create issues some times in the local file system) and very easy to use. It’s social collaborative capabilities are awesome but also supports private projects however this latter feature it’s not free. Also there are tutorials online.
