Whilst the weather may have put some off venturing out, not for our intrepid duo of presenters – Joost Volker (Oracle PM for a Blockchain) and Robert van Mölken Oracle Groundbreaker Ambassador and author of Blockchain Across a Oracle who both had to negotiate protesting farmers, traffic jams, flight delays (wrong kind of rain to land in London) and London’s rush hour traffic.

Last night was the London Oracle Developer Meetup’s sessions around observability. Andrei Cioaca with a focus on the use of OpenTracing as provided by Jaeger, in a standard Kubernetes deployment with Istio – realized with Oracle Kubernetes Engine (OKE). This was followed by my session on another pillar using logging via FluentD. Also incorporated into standard Kubernetes, but also able to support traditional monolithic use cases.

Andrei provided a great overview of the 3 pillars and the strengths and weaknesses of the different pillars. With the basics covered Andrei then dove into the configuration and execution of Istio combined with Jaeger and the corresponding insights available. including a look at the kinds of visual insights that Jaeger and Kiali provide. Some probing conversations followed about the relationship to Spring Cloud Sleuth, Open Zipkin and the OpenTracing as a concept more generally.
Andrei’s presentation material can be found in his GitHub repository here.

My session followed a pizza break, as there was a delay in its arrival. With everybody having chatted over pizza about OpenTracing, we picked up on FluentD and the Logging aspect to Observability. FluentD, as an open-source project has been growing steadily, and actually baked into several Log Analytics products and services – as the above analytics from Google shows.
The presentation looked at the growing challenges of modern software in terms of making sense of logging. We explored the capabilities of FluentD before drilling into real-world use cases and potential deployment models.
As you’ll see from the slides we ran a couple of demos. The configuration for the demos can be found at https://github.com/mp3monster/fluentd-demos along with an example payload.
The next meetup we have organized is around Blockchain, all the details can be found at https://www.meetup.com/Oracle-Developer-Meetup-London/events/264661742/.

This Meetup was put together quickly as it presented an opportunity to align with other events happening in the Oracle offices. Despite the relatively short notice we a turn out that really made great use of our speaker – Sid Joshi who walked through the Enterprise Level patterns supported by Oracle’s Integration Cloud (OIC) including a demo showing how PaaS4SaaS worked using Service Cloud and OIC making use of VBCS and integration (formerly ICS) parts of the API Platform.
As with all the meet-ups we allow the discussions to flow freely. So, the conversation probed different aspects of OIC. So with the follow up on Several Capgemini use cases of OIC that have won the team awards.
You can see these use cases here. Sid’s presentation is available AppIntegrationPatterns_MeetUp. Additional resources can also be obtained from https://oracle-integration.cloud
As the conversation has focused on OIC and the use cases rather than our ongoing Drones with APIs stories, I have had an interesting follow on discussion about the application of drones. The drone story has many threads. The initial driver for the work on the drone has been about bringing something interesting and distinctive to the meetup. The drone is very tangible, and the source of amusement which makes the meetups a lot more fun.

It’s been a quiet month for this blog, but I’ve been pretty busy with a raft of other activities…
Reviewing a new book on Enterprise API Management for Packt which we would very highly recommend if you want to understand the more Enterprise perspectives of adopting APIs, particularly if you’re considering APIs as a potential new revenue stream.

One of the things I am fortunate enough to get involved with on occasion is the Oracle Groundbreakers Podcast (previously known as the Oracle Developer Podcast) and something I have written about in the past, even as Oracle Developer Community (ODC) Appreciation Day post.
As a result of the recent Meetups on the subject of Helidon that have been occurring recently, we made the suggestion that Helidon is the subject of a Groundbreaker’s Podcast, net result I was invited to be part of the panel. The podcast was recorded a few weeks ago, and know available (here). Go check it out, as it includes the key contributors to the project Dmitry Kornilov and Tomas Langer.

Another Spring means another excellent Oracle EMEA PaaS Forum for Oracle partners. Every Year Juergen Kress organizes the event, finding really nice venues to host several hundred people over four and half days.
The event is split into several parts, Monday afternoon normally involves Oracle Ace’s presenting on best practices, insights on applying the various technologies etc. For me this meant presenting on the London Developer Meetup, looking at how it worked, what has been successful, and what hasn’t. For those know have read my blogs on the subject (here) will know about our Drone initiative.

Then Tuesday is a single stream day where Juergen has managed to pull in SVPs and Senior Product Managers from around the globe to provide a high-level view of what has been going on with their products. For anyone consulting in the Oracle domain, this is incredibly useful. For example, there is a clear strategy coalescing around AI and Machine Learning both as a service proposition to users, but also how these technologies are being made available and used within other products. Other areas such as OIC and SOA CS have stability and maturity, and the road map is about maximising connectivity with the newer products.
But before the sessions start, Juergen starts with opening remarks, and demos’ something engaging. In previous years this has been things like Digital Assistants/Chatbots and so on. This year, we have been fortunate to be an active contributor by demoing the drone through the use of APIs and talking about the ideas. The dry runs of the demo on Monday went without a problem, but when it came to the main show, the drone was a little uncooperative – we think because the air-con had really kicked in. But importantly, even not achieving the desired result, the message of engagement made it home.
Wednesday is split into streams with in-depth sessions from the different Product Managers, he amount of insight gained from these sessions is tremendous, some of which is very much protected by safe harbour statements or not for public disclosure such is the honest and open discussions. The day closes with an Ace Director initiative which demonstrates the application of Oracle Cloud products to a plausible use case, and Luis Weir (Capgemini Oracle CTO) is part of. This session has become something of a tradition now.
The day’s business concludes awards, and for a second year the UK Capgemini team have taken home two awards for APIs and PaaS Contribution.

The final two days are then a choice of Hackerthon or 1/2 day training sessions on different products with the relevant Product Managers, and an excellent opportunity to pick the brains of the presenters as well as get hands-on experience with the different products.
The week isn’t without it’s social and networking activities of course …

Last night was the first Oracle Developer Meetup in London for 2019. We were very fortunate to have Tomas Langer fly over to talk about the new micro container/framework being developed as an open-source solution by Oracle.
Tomas, opened by explaining the evolution of the micro-profile being championed by the Eclipse Foundation who are now the guardians of J2EE also known as Jakarta and how the J2EE and Micro-Profile standards compare (in simplistic terms – micro-profile is J2EE stripped back to be simple and support what is typically needed in a micro-service world).
The presentation then went onto compare Helidon SE and Helidon MP (micro-profile). What was really pleasing is that with a couple of exceptions everything that Helidon MP can do, can be done in the SE edition, the difference being that for SE you have to implement more code, rather than the auto-magic of annotations, but in return you have a Reactive Java platform with a development paradigm which relates to JavaScript Express.
In addition to talking about what can be done, Tomas described the kinds of features being developed, this includes:
With the scene set, Tomas then worked through a series of live code scenarios starting with a clean slate and building Hello World in both the SE & MP models illustrating the differences in approach. This was then built upon to add the following capabilities:
You can get the complete example which uses Helidon in both configurations from Tomas GitHub.
In addition to Helidon itself on GitHub, there are resources provided include rich documentation and examples of each key feature. Plus a Slack community, that if you contact any of the Helidon team will get you invited allowing you to discuss with the development team how to do things along with other developers using Helidon.
Tomas can be contracted via @Langer_Tomas. Helidon project also has its own Twitter account – Helidon Project
Helidon itself can be found at:
I have previously blogged on Helidon at Exploring Helidon – Part 1

The London Oracle Developer Meetup (here) are excited to say that on that we’ll have 2 of the lead engineers with us from the Helidon.io project with us to introduce and demo the new open-source micro container platform. Bring your laptop and code along if you like.
Hope to see you there.

Last night we ran the latest of the Oracle Developer Meetups in London. This time Luis Weir presented on GraphQL, which got an very engaged discussion about the strengths and weaknesses of GraphQL, in-depth points about how the error paths should be handled among many other things.
The presentation material Luis used is based upon his Devoxx session earlier this year and can be seen here:
The links to Luis’ examples can be found on his GitHub account – https://github.com/luisw19/graphql-samples
After a insightful and thought provoking presentation on GraphQL the Drones with APIs project had its latest update. Providing a lot of laughter to the evening’s proceedings. Including demonstration of flying the drone using REST APIs published via a gateway and Go back-end. This included the DroneDash presenting a visual presentation of the commands being issues via REST, as seen here:
All the code, API definitions and documentation for people to add or extend can be found in the meetup’s GITHub – https://github.com/oracledeveloperslondon/.
A few of the useful links used or mentioned last night are:
The next meetup is planned for Monday November 19th. Topics will be published soon.

We have been fortunate enough to participate an ArchDev podcast about meetups – https://oracledevs.podbean.com/e/pizza-beer-and-dev-expertise-at-your-local-meet-up/
The podcast talks about the differences between the meet-ups and events such as conferences, what we try to get out of a meetup and the effort put into arranging them.
For more info about the meetup I help organise checkout out https://www.meetup.com/Oracle-Developer-Meetup-London/events/249256400/
We’d also like to thankyou Jurgen Kress and his team for all the behind the scenes work that means the London Dev Meetup events can happen and ensure all are suitable feed and watered.
