SOA vs Microservices Architecture by The SOA mythbusters

So, are you interested in SOA & Service Orientation technologies?, that’s great because we also are, and work with those every single day since a long time ago. As integration professionals, we’ve seen the SOA stack grow, change, incorporating new products and technology with each passing year.

We’re  Arturo Viveros and Rolando Carrasco, the SOA Myth Busters from Mexico, and as we go with this series we will  put to the test a number of questions, myths and urban legends regarding SOA, Digital Transformation and much more, in seek of finding out which myths are true and which are not.

Introduction

Microservices Architecture is one of the disruptive technologies which have definitely taken center stage in these early days of the Digital Transformation era. Its fundamentals and value proposition are very appealing and in context with many of the architectural and functional needs of modern platforms and initiatives, so let’s begin by taking a quick overview:

ed 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”“In short, the 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 automat

The above definition by Martin Fowler is fairly simple and at first sight doesn’t really introduce any extraordinary or revolutionary concepts. However, the best way to understand this architectural style as well as its differentiators and potential benefits, is contrasting it to what we may call traditional “monolithic” architectures:
With the term “monolith” being one of the most dreaded in IT lore, the design principles for which Microservices stand for become even more impactful: Read the complete article here.

Accessing and Analyzing Twitter Feeds with Oracle Stream Analytics (Part 2) by John Featherly

In Part 1 of this series we saw how to setup a connection in Oracle Stream Analytics to Twitter and create a Tweet stream. In this part we will investigate using the OSA map and geo-spatial exploration features to display the tweet point of origin on a map.

Location Aware Tweets

Notice that tweets do not by default include the location information (latitude and longitude) of the post. Missing location data is set to minus one on the tweet as shown below.

In order to include location information, post from a mobile device that has location (GPS) hardware. Enable location on the tweet and turn on “Share precise location” as shown below.

Now that we have tweets with location information the next step is to create a map display in OSA to get visual display of point of origin.

OSA Maps and Patterns

The map item allows you to set a rectangular region of the globe and “geo fences” which will display highlighted markers if location data in the stream is contained within the fence. Start by creating a new Map item. Read the complete article here.

An Introduction to Oracle Stream Analytics by Robin Moffatt

Oracle Stream Analytics (OSA) is a graphical tool that provides “Business Insight into Fast Data”. In layman terms, that translates into an intuitive web-based interface for exploring, analysing, and manipulating streaming data sources in realtime. These sources can include REST, JMS queues, as well as Kafka. The inclusion of Kafka opens OSA up to integration with many new-build data pipelines that use this as a backbone technology.

Previously known as Oracle Stream Explorer, it is part of the SOA component of Fusion Middleware (just as OBIEE and ODI are part of FMW too). In a recent blog it was positioned as “[…] part of Oracle Data Integration And Governance Platform.”. Its Big Data credentials include support for Kafka as source and target, as well as the option to execute across multiple nodes for scaling performance and capacity using Spark.

I’ve been exploring OSA from the comfort of my own Mac, courtesy of Docker and a Docker image for OSA created by Guido Schmutz. The benefits of Docker are many and covered elsewhere, but what I loved about it in this instance was that I didn’t have to download a VM that was 10s of GB. Nor did I have to spend time learning how to install OSA from scratch, which whilst interesting wasn’t a priority compared to just trying to tool out and seeing what it could do. [Update] it turns out that installation is a piece of cake, and the download is less than 1Gb … but in general the principle still stands – Docker is a great way to get up and running quickly with something

In this article we’ll take OSA for a spin, looking at some of the functionality and terminology, and then real examples of use with live Twitter data.
