So this week the big Developer Week Europe conference is running online at the moment. I got to present today. It was a relatively short session, with an unfortunate brief interruption of a smoke alarm. My presentations is here …

The latest edition of OraWorld has become available to today. With its blend of insight into the Oracle community, and Oracle technologies from database to modern apps. I have to own up and say, I mention the magazine not only because of the beautifully crafted independent insights, but also it includes an article from myself. Taking a look at GraphQL what it is and how recent new Oracle product features could make a big difference to the GraphQL adoption opportunities.
The next edition should include a follow up article to this focussing on API security considerations.

We have had a requirement from a customer to be able define every package including dependencies within a Node solution (as it happens Apollo GraphQL), not only the complete download path but the version numbering as well. There are many ways to solve this problem. But here is an elegant(?) and portable answer. To ensure that we don’t get pollution from a global node space we created a project package in an empty folder using:
npm init --yesThis defaults all the package,json settings which for our requirements is fine. Then in the same location its npm install <product from the npm registry to pull> e.g. for Apollo GraphQL:
npm install apollo-server graphql
This will bring down to your npm project all the dependencies putting them in the node_modules child folder. We’re now in a position to retrieve all the details of the packages, their dependencies and version information. This can be done by using the command:

The book has had a title change as Manning found that links the book was clashing with other solutions using the term ‘Unified Logging’. With the name change it helps bring the book inline with the Manning naming with their In action series. This means the book website is now https://www.manning.com/books/logging-in-action.
With the name change we’ve agreed that there should an additional chapter added. As I’d written the book with a view that everything we cover applies to both modern solutions such as Microservices coming from the CNCF camp but equally relevant to more traditional IT landscapes. Within the book we have explianed how things are positioned and can be used in Kubernetes, but it was agreed with our editorial team that not tackling the configuration of Fluentd with Kubernetes and Docker was to an extent ignoring a key community that will be using Fluentd. So the new chapter will be introduced to address this aspect.
In terms of progress we’re into the 1’s – 1 Chapter to start (the new one), 1 Chapter back from the Technical Editor (Logging Best Practises) – some edits to be done, 1 Chapter now with the editor (How To Create Custom Plugins), 1 Chapter being finished (Logging Frameworks) and finally 1 peer review cycle to go.
Given the lovely review comments that have been quoted on the book’s page. I can only recommend if you have an interest in logging and monitoring then check it out through Manning Early Access Programme (MEAP).

I was fortunate enough to record a podcast with the team at Adventures In Dev Ops just before Christmas. The recording has been fine tuned and now available on their web site here. From my perspective, the discussion was really interesting and explored a wide range of areas around the challenges of monitoring.
As the podcast is linked to the book we’re writing for Manning (Unified Logging With Fluentd), there is a discount code currently running – poddevopsadv20.
Thanks to Charles Wood and Jeffrey Groman for having me on as a guest.
I will be presenting at the online conference Blueprint LDN, check out the subjects being covered, looks very interesting.

I’ve not posted about the developer meetups for a little while, perhaps because with everything being virtual these days things blur together too much. But its time to put that right (at least a little). So over the last couple of month’s we’ve been fortunate enough to have a couple of Oracle’s guru’s from the A-Team covering some pretty interesting topics.
November saw Chris Peytier exploring the process management side of Integration Cloud and how process management and more traditional integration can come together to offer a very effective solution with example use cases such as the idea of when conditions are not valid for an integration to be executed Chris’ slides are here.
Then this week we had Angelo Santagata complete with Santa hat talking about Serverless as a means to enable SaaS extensions and integrations through the use of Oracle Functions (the cloud-deployed version of Project Fn). You can get the presentation here.
If the slides aren’t enough then you can catch the presentations as videos, Angelo’s is here and I’m sure we’ll see Chris’ made available as well.
I’m excited to say that we have a coyuple of presentations lined up for 2021 already so keep an eye on the London Oracle Developer Meetup. So watch out for the updates in the new year.

My blogging is way down compared with only a post about OKit – OCI Design (on Windows). It largely comes down to lots of work on our Fluentd book. Chapter 6 is now available in the MEAP. As the promo info says …
What’s new?
Chapter 6, “Filtering and Extrapolation”
Gain control and insight!
Last chapter, we touched on the use of the Filter directive. But that was just the tip of the iceberg! In Chapter 6, we’ll plunge below the surface, exploring the when, why, and how of applying filters to give us more insight and precise control over events.
Promo Email from Manning
Earlier chapters have been tweaked, with some additional improvements which will make the live reading experience better.
Another chapter and an appendix should be finding their way to MEAP very soon as it was handed over by our project editor. That will make it seven chapters available, and all the appendices.
Whilst the peer review is taking place the chapter covering plugin development is progressing. The development work has got the basics of the output plugin with log events being stored in Redis and the input being worked on as well. If you want a peak, keep an eye on my GitHub repository (here).
I presented on Twitch – you can catch that at https://m.twitch.tv/videos/809295979 I’ve been offered the opportunity to present again, so keep an eye out for something next year.
We recorded a podcast with the excellent guys over at Adventures In DevOps. We don’t have the exact date for the podcast to be released, but I imagine it will sometime during Jan 2021. I’d recommend checking out the podcasts. I’ve been dipping into their back catalogue of recordings and the team ask some really thought provoking questions.
If that wasn’t enough, we’ve been fortunate enough to have some time to talk with leading members of the Fluentd and Fluent Bit projects which was a real pleasure. Hopefully, as we leave this horrendous year behind we’ll get to talk and possibly collaborate some more.

OKit is a tremendous tool for the visual design and development for your Oracle Cloud environment. Visualizing your networks, positioning of service gateways and so on makes it a lot easier than filling in web forms or writing Terraform files as you can see the relationships between the different parts far more easily. For the same reason really that a lot of people use Visio and other tools for this work. The real beauty is that OKit can generate the Terraform and Ansible scripting that can then be used to deliver the implementation.
The tool isn’t currently an official Oracle product, but something built by the Oracle A-Team (a small team of gurus who have a role blending developer advocacy, architect supporting customers for the special edge cases and providing thought leadership). But we can hope that someone brings it into the fold and perhaps even incorporates it securely into the cloud dashboard. In the mean time, the code in its entirety is available on GitHub.

Things have been very hectic, so much so we’ve not really had much time to write a blog. Most of which has been related to my Fluentd book, so what has been happening (and keep an eye on my Twitter account for a promo code 🙂 ) …
So what is to follow:
Talking of Manning on Twitch, this looks like a bit of a hidden Gem – worth looking at not only because of the live stream, but all the previous recordings with other Manning authors are available to watch.
If that isn’t enough with a day job, we have had some major work done on our house. Now we’re moved back in, there are lots of DIY jobs to do, get all the furniture back from storage. Every room apart from the kitchen needs to be painted. But that is my sob story.
I’m hoping to find time to experiment with Oracle’s new cloud native Log Management as this is built on Fluentd foundations and a little bit with API tech – but this is likely to be the Christmas break.

Oracle’s data integration product landscape outside of GoldenGate has with the arrival of Oracle Cloud been confusing at times. This has meant finding the right product documentation can be challenging, and knowing which product to use in your own technology road-map can be harder to formulate. I believe the landscape is starting to settle now. But to understand the position, let’s look at the causes of disturbance and the changes that have occurred.
This has come from I think a couple of key factors. The organizational challenges triggered by Thomas Kurian’s departure which has resulted in rather than the product organization being essentially in three parts aligning roughly to Infrastructure, Platform and Applications to being two Infrastructure and Apps. Add to this Oracle’s cloud has gone through two revolutions. Generation 1 now called Classic was essentially a recognition that they needed an answer to Microsoft, Google and AWS quickly (Oracle are now migrating customers off classic). Then came Generation 2, which is a more considered strategy which is leveraging not just the lowest level stack of virtualization (network and compute), but driving changes all the way through the internals of applications by having them leverage common technologies such as microservices along with a raft of software services such as monitoring, logging, metering, events, notifications, FaaS and so on. Essentially all the services they offer are also integral to their own offerings. The nice thing about Gen2 is you can see a strong alignment to CNCF (Cloud Native Compute Foundation) along with other open public standards (formal or de-facto such as Microprofile with Helidon and Apache). As a result despite the perceptions of Oracle, modern apps are standard a better chance of portability.
Oracle’s Data Integration capabilities, cloud or otherwise have been best known as Oracle Data Integrator or ODI. The original ODI was the data equivelent of SOA Suite implementing Extract Load Transform (ELT) rather than ETL as it meant the Oracle DB was fully leveraged. This was built on the WebLogic server.
Oracle cloud came along, and there is a natural need for ODI capabilities. Like SOA Suite, the first evolution was to provide ODI Cloud Service just like SOA Suite had SOA Cloud Service. Both are essentially the same on-premises product with UIs to manage deployment and configuration.
ODI’s cloud transformation for the cloud lead ODI CS evolving into DIPC (Data Integration Platform Cloud). Very much an evolution, but with a more web centered experience for designing the integrations. However, DIPC is no longer available (except possible to customers already using it).
Whilst DIPC had been evolving the requirement to continue with on-premises ODI capabilities is needed. Whilst we don’t know for sure, we can speculate that there was divergent development happening creating overhead as ODI as an on-prem solution remained. We then saw the arrival of ODI Marketplace, this provides an easier transition, including taking into account licensing considerations. DIPC has been superseded by ODI Marketplace.
Oracle has developed a Marketplace just like the other major players so that 3rd party vendors could offer their technologies on the Oracle cloud, just as you can with Azure and AWS. But Oracle have also exploited it to offer their traditional products normally associated with on-premise deployments in the cloud. As a result we saw ODI Marketplace. A smart move as it offers the possibility of exploiting on-prem licensing into the cloud along with portability.
So far the ODI capabilities in its different forms continued to leverage its WebLogic foundations. But by this time the Gen2 Oracle Cloud and the organizational structures behind it has been well established, and working up the value stack. Those products in the middleware space have been impacted by both the technology strategies and organization. As a result API for example have been aligned to the OCI native space, but Integration Cloud has been moved towards the Apps space. in many respects this reflects a low code vs code native model.
Earlier this year (2020) Oracle launched a brand new ODI product, to use its full name Oracle Cloud Infrastructure Data Integration. This is an OCI native (i.e. Gen2 solution leveraging microservices technologies).
This new product appears to be a very much ground up build as it exploits Apache Spark and Function as a Service (FaaS) as foundational elements. As a ground up build, it doesn’t inherit all the adapters the original ODI can offer. This does mean as a solution today it is very focused on some specific needs around supporting the data movement between the various Oracle Cloud storage and Database as a Service solutions rather than general ingestion and extraction processes.
Products are evolving, but the direction of travel appears to be resolving. But we are still in that period where there are capability gaps between the Gen2 native solution and the traditional ODI via Marketplace solution. As a result the question becomes less which product, but when and if I have to invest in using ODI Marketplace how to migrate when the native product catches up.
