In this blog I’m going to explain how to monitor your IoT or other devices without having to open up ports, install agents or require access to your network. We will rely on Node-RED, Azure LogicApps and Azure Monitor Alerts.Continue reading “Monitor (IoT) devices with Node-RED and Azure LogicApps”

It is really easy to blow all your budget when you do not know the impact of the choices you make in the cloud. And while there are many tools available to run analysis on your bill, or showing where your money went, would it not be smarter to shift everything left?
34 per cent of large enterprises set a budget of at least $10m a year while 62 per cent of small business went for under $100k. Of those spanking between $2m and $10m on the cloud, almost half overspent (compared to 27 per cent of those budgeting until $100khttps://www.hashicorp.com/blog/cloud-budgets-busted-almost-40-overspent-last-year

If I would get paid a euro for each time someone says ‘Let’s spin up a VM for that!’ or ‘We have this VM running anyway’, I would have been a rich man.
Although I do advocate reuse, stuffing many services on a machine ‘because it runs there anyway’ will cause a huge problem if there is a shift in architecture or platform. In the end all services need to be carved out and that can be a real pain in the behind. Also it does not really scale, for obvious reasons.Continue reading “Why you should stop spinning up VMs”

I’ve written in a previous blog that for writing maintainable code, you really should automate your tests. Currently we see Terraform really taking off as the standard to provision and deploy almost everything in cloud like Azure and AWS. In this short blogpost I will show how you can start testing your Terraform code using the Open Policy Agent.Continue reading “Everything is Code. Why and how you should test your Terraform”

Spoiler alert; no.
Low code vs Traditional Dev
My colleague, friend and SogetiLabs Fellow Daniel Laskewitz and I frequently talk about this topic. His field of expertise as Microsoft MVP covers the Microsoft PowerPlatform including low code systems like Power Automate (formerly Flow).
All too often people see a division between low code and traditional development using languages like C#, Java, TypeScript and Go.
In the real world however, these systems work together perfectly.
Most of the times, you cannot solve a problem with only low code. Think about scenario’s where you should link to old legacy systems or complex API calls. In those cases low code without any enhancement cannot natively connect to those systems.
Behold custom connectors
In the Microsoft ecosystems, custom connectors allow you to bridge this gap. This way, the low code system can interact with any system you write a connector for. This may be common knowledge, but the fact is that most developers do not see how big this really is.
This means you can link any PowerApp, Microsoft Flow, or LogicApps to your custom connector, and reuse those within your entire organisation.
You could even publicly publish these if you have a service you want to expose. So if you are an ISV, this can help you get more traction on your product.
Bridging the gap
In the end it all comes down to developers of any system and language understanding the capabilities of the platforms they and their companies are using. For low code developers this means sometimes calling in the help of traditional developers. And more importantly, this also means traditional developers should learn that these low code systems can help you simplify (and thus speed up!) your development by using ready-to-roll systems and connectors available to you.
As there are over 325 connectors available, that should really speed making connections up!
Want to explore custom connectors? Look at these resources or feel free to contact me or Daniel, we strongly believe bridging this gap between low code and traditional dev is key for succes in the future of development!
Hashicorp has done a terrific job making Terraform with the ability to template any API, and deploy and manage stacks in Azure, AWS and many, many more.
I’ve been following Pulumi for a while, and their approach is a bit different than the previous stated tools.
Sometimes it is hard to keep your spouse up-to-date on all the sessions and events work-related. Most of the times I’ve been able to duplicate calendar items that are relevant for my ‘better half’.
Obviously manual work makes me sad and I forget to sync some events causing a collision in the calendars. If, like me, you have kids you’ll understand this results in hoping your babysitter can make time because you forgot to add some items in your calendar manually.

The shift to cloud, and with that, to PaaS services or low code alternatives like LogicApps push the actual code developers see and use to the background.
There is an ISO standard on software quality, and the maintenance best practices are well written and explained in the book Building Maintainable Software. Within low code systems, applying these guidelines can be less obvious and it can be a difficult task automating and testing the quality of your code with tools like SonarQube.
Should we even worry about the underlying code? Absolutely. The principles still adhere and creating a spaghetti of your low code systems can cause major issues on maintenance or adding new features.
Let’s focus on three points of the maintainability guidelines:
- Write code once
- Couple architecture components loosely
- Automate development pipeline and tests
In no way these are the most important items, but for this example an easy entry into the low code space.
1. Write code once
Just like any other audit of software, you still can avoid writing duplicate code. In a platform like LogicApps it can be easy to repeat a custom call to something like a custom HTTP API.
In traditional languages like C#, you have many options to reuse your code. You could create a library, or you can create a package and make it available via NuGet. Within low code systems, these same packaging mechanisms not always exist.
Taking the example of LogicApps, the solution could be to create Custom Connectors. These will wrap your custom API calls into a reusable component you can share within your organisation, or even outside.
2. Couple architecture components loosely
If your components are tightly coupled, it can be troublesome to replace or refactor your components. The impact will be on each and every other component that has a high coupling with your part.
Again taking the LogicApps for example, let’s state our LogicApp calls another component directly using HTTP. The Azure Portal gives you this out of the box, letting you call Azure Functions directly from your LogicApp.
This goes agains the principle of loosely coupling. The reason is that your call is directly bound to that function, so changing the interface or location of your function, impacts the LogicApp directly. In this case, it would simply break and stop working.
To solve this problem, a simple solution is to decouple the LogicApp and the Azure Function using a queueing mechanism. This way, the message to the Azure Function is put on a queue by the LogicApp, and the Azure Function listens on a queue. Now, if the developer of the Azure Function changes location or even use another platform, there is no need to change the LogicApp.
Obviously this would require you to make an agreement on the contents of the messages on the queue.
3. Automate development pipeline and test
Automating your CICD pipelines allows you to more easily build, test and deploy your code. In case of a language like C# or Java, you can easily run tests, build your code, and create packages or deployments. A tool like Azure DevOps can combine these steps and lets you create a wealth of quality gates, checks and processes to guide your team.
When using low code platforms, it can be cumbersome to get the code into your version control systems. Nevertheless, many of those platforms do give you the tooling. LogiApps for example has template creators, and systems like OutSystems have their own CICD ecosystem.
In the end the automation allows you to more easily add steps to your CICD process, and allow you to deploy more frequently without any hassle. The addition of automated testing will absolutely be beneficial to the overall quality of your product.
Treat your low code just like you would any other codebase. Almost all guidelines of mainainability can be mapped to your product. Some can may require a bit more investment, but in the end I truly believe it will help building a maintainable and high-quality (low) code base.
