Should I use Logic Apps or Azure Functions?

There are multiple ways to resolve the same business problems using Azure Services. Numerous times I was involved in a discussion where Azure Logic Apps and Azure Functions were put side by side. In this post I would like to build another perspective of these two Azure services and when we shall use one or another, taking into account our functional needs and expectations. Service Overview Azure Logic Apps allows us to build workflows that are runnings as a service inside Azure, that can scale automatically and can be integrated with a high number of services from Azure or on-premises systems. Azure Functions are the serverless offer from Microsoft that are highly scalable, well integrated and ready to respond to our future need. Why is it hard to decide? A part of the functionality offered by these two services overlaps or are similar. Decided on what business scenarios we shall use one or another it is not easy. Besides this, both services are so well integrated, that you

Nevertheless, even if the format was different because it was a working day, more than 35 people joined the event and wanted to discover the Visions features that Cognitive Services are offering. Besides this, together with Florin, we wrote, deployed and integrate an Azure Functions in less than 45 minutes. It was the best way to show to people how easy we can define and run serverless functions inside Azure. Below you can find the content from the event. See you next year!

Microservices and Serverless Computing | Pros and Cons

All of us heard about the success of Netflix, Uber or eBay. All these companies went on an approach based on falt tolerance system developed on top of microservices and serverless computing. Nowadays people are trying to replicate their success and build systems that take advantage of this new way of designing software solutions. The complexity of a system that is built now in comparison with systems that were built 10 or 20 years ago is different. The complexity is not only higher, but also the NFRs and SLA are tighter. The expectation from the customers is availability that goes as close as possible to 100% with less money and smaller teams. It can be achieved only with the new paradigm of software development on top of microservices and serverless approach. We are in the moment in time when architects and technical leads are realising the advantages that serverless and microservices approach brings. They are trying to adopt as fast as possible the new ways of designing ap

Different ways of buying Azure Services (Pay-As-You-Go, EA, Direct CSP, Indirect CSP)

How do you buy Azure Services? This simple question it's tricky in most of the cases. For many companies, it is not clear how they buy Azure Services, what kind of provider they are using. Additional to this, they don't know what the difference between different ways of buying resources and which one is more suitable for their needs is. Let's take a look at the 4 different ways on how we can buy Azure Services and try to identify the pros and cons of each option. Direct from Microsoft You can buy Azure Services directly from Microsoft. It means that the invoice is generated directly by Microsoft, and any issues that you have will be handled directly with them. This provides you with a clear process related to how tickets and incidents are handled and a direct link to Microsoft support. Even so, because you interact with support, they might ask you initially some dummy questions that help them to understand better your business and technical problem. Besides this, M

[Post Event] Visual Studio 2019 Launch Event

On April 2nd, 2019 Microsoft launched the new version of Visual Studio - VS 2019. In Cluj-Napoca, we organised a special event party where we broadcasted the event. Additional to this, we had 3 sessions where we presented the new features of VS 2019. The sessions were focused on code review, remote debugging and writing code with the support of AI - Intelli Code. I had the opportunity to talk about Visual Studio IntelliCode, a smart way how the IDE can learn about your code and the way how you write code. Using this information, the IDE can provide you with better recommendations related to what method you shall use taking into account the context. Event summary: What we'll do! Visual Studio 2019 Launch Party! April 2nd, 2019 Visual Studio 2019 is here! On April 2nd we will broadcast a full day of awesome Visual Studio 2019 technical content to celebrate the launch and get you up to speed with all the new features. Local agenda: 18:00 -
