Combining Web and OSGi Components

I consider myself a latecomer to Microservices; I only really started to understand and use them in 2005. Nobody called them “Microservices” at the time – as far as I can tell, the term was coined in 2006 by BEA for their microService Architecture (mSA). Regardless, with this history it was a little surprising to hear the term reinvented in 2014 and suddenly gain a great deal of traction. While implementation details vary, the fundamental (more…)


Functional Transaction Management – old dog, new tricks! 3 comments

This blog post is all about the new Transaction Control service which is proposed to be part of the next release of the OSGi Enterprise Specification. Paremus has been leading this specification work, which arose from a collaboration with one of our customers, McCarthys. The current state of the RFC is available on GitHub, and there’s even an implementation available in Apache Aries.

Before we delve into the cool features of the Transaction Control service, it’s probably worth remembering why we need yet another transaction abstraction… (more…)


The Paremus Service Fabric has no Opinions…

The emergence of the ‘Opinionated’ Microservices Platform continues apace.

We are told that business systems should be REST/Microservice based. We are told that containers should be used everywhere and container images are the deployment artefact du jour: I mean lets face it Virtual Machine Images are so last year! And of-course Reactive is the new cool.

A depressing state of affairs. These messages are at best half-truths. At worst – the IT industry’s ongoing equivalent of Snake Oil.

Modularity, Microservices and Containers

My colleague, Derek Baum, had an article published in Jaxenter last week called “Modularity, MicrJaxenter Feb 2016oservices and Containers“.

The article discusses how Microservices and Containers are examples of a general industry drive towards modularity. It goes on to demonstrate how OSGi’s Service-centric approach, its Requirements & Capabilities model, and the OSGi Remote Services specification provide an excellent solution for a containerised microservices solution.

Yes thats right, these concepts/technologies/trends aren’t competing with each other as many would have you believe. In fact they can all be complimentary when used with Paremus Packager.

Paremus Packager integrates the lifecycle of external (non-Java) applications with OSGi and provides a consistent means to start, stop, configure and inter-connect services and we will be making an early access release of the new Docker-based Paremus Packager available to a restricted audience in Q1 2016.  You can sign up for this online with just your email address.

The article is a is a follow up to the presentation of the same name given at the OSGi Community Event in 2015, by Neil Bartlett [ Slides / Video ] and these are a good source of info if you would like to learn more. Of course you can also add comments below if you have any questions.


Asynchronous Event Streams @ MadridJUG

Some of the Paremus team were in Madrid last week (Jan 11 to 14, 2016) for the OSGi Expert Group meetings and also an OSGi Alliance Board Meeting.

While we were in town, our CTO, Tim Ward, was invited to speak at the MadridJUG on the work he has been leading within the OSGi Enterprise Expert Group on Asynchronous Event Streams. This relatively new OSGi Alliance specification is highly relevant to the use of OSGi in IoT as well as in Enterprise.

The subject proved to be an interesting topic to the MadridJUG members with good attendance and lots of questions.

Thanks to Liferay Spain (@liferay_es) for hosting the Meetup and MadridJUG (@MadridJUG) for inviting Tim to present.

 

Tim also presented this talk at the OSGi Community Event last year and you can find a video of this here and the slides here.

 

It looks like the OSGi Alliance will be having face to face meetings in Chicago, Ghent and Ludwigsburg in the coming months. If you are interested in getting someone from Paremus to come and present on anything OSGi or our products while we are in your neighbouthood then please let us know.
