Creating a solution with multiple small services is great of course. It provides you with a lot of flexibility and scalability.
There are however a couple of things you have to think about when designing and developing a solution with multiple services. One of the things you need to figure out is how to implement proper logging. For an actual production system you need to have this in place in order to monitor and debug the overall solution.

I’m not the only one who will be speaking over there, there’s also a great session by Henry Been (SnelStart) and an awesome talk from Christos Matskas (Microsoft).
I myself will be talking on how to create a serverless solution using Azure Functions. This of course is a very broad subject and I’d like to know what you think I should focus on or what you would like to see covered in this session?
Read more →Using certificates to secure, sign and validate information has become a common practice in the past couple of years. Therefore, it makes sense to use them in combination with Azure Functions as well.
As Azure Functions are hosted on top of an Azure App Service this is quite possible, but you do have to configure something before you can start using certificates.
Adding your certificate to the Function App Let’s just start at the beginning, in case you are wondering on how to add these certificates to your Function App.

Well, as it goes, the same post applies for Azure Functions. You just have to do some extra work for it, but it’s not very hard.
Simon Pedersen, the author of the Azure Let’s Encrypt site extension, has done some work in explaining the steps on his GitHub wiki page.

By leveraging the power of bindings, you don’t have to write your own logic to store or retrieve data. Azure Functions provides all of this functionality out of the box!

Having a continuous integration and -deployment environment is the norm nowadays, which means I (and probably you as a reader also) want to have this when creating Azure Functions also!
There are dozens of build servers and deployment tools available, but because Azure Functions are highly likely being deployed in Microsoft Azure, it makes sense to use Visual Studio Team Services with Release Management.
Read more →As with almost every application there is a point where you have to work with some kind of secret, like for example a connection string to a database. There are multiple ways to retrieve these secrets and this isn’t any different with Azure Functions.
If you have set up a continuous deployment build within Visual Studio Release Management you can just substitute the values in your build, which makes it easy, transparent and consistent to add and change the values.
Read more →Lately, I’ve been busy learning more about creating serverless solutions. Because my main interest lies within the Microsoft Azure stack I surely had to check out the Azure Functions offering.
Azure Functions enable you to create a serverless solutions which are completely event-based. As it’s located within the Azure space, you can integrate easily with all of the other Azure services, like for example the service bus, Cosmos DB, storage, but also external services like SendGrid and GitHub!
