Microservices and Team Setup - Is not only about code

Solutions that are based on microservices architecture become a commodity. Teams are not afraid anymore when they found out that the next projects is based on micro-service architecture.

The transition from messaging base architecture to microservices architectures was very useful for team to understand the main concept and how a solution should look like.

Trigger

Working with different frameworks or tools specific to microservices will make the team curious and happy at the beginning. Most of the people are happy when they have team allocated to learn new stuff. But after this phase, I identify that there is usually a collapse. In the first moment when we are ready to start 'production' code, people starts to have hiccups and each of them have problems when they need to make a deploy, run their code in containers and so on.

Cause

It is easily to forgot or to ignore that microservices is not only at service/code level. It is also at infrastructure level. There is a lot of scripting and automation that needs to be done to be have a success story.

Even testing your own code is not so easy anymore. You microservice will need to run in a sandbox or you need also the services around you own service to be able to do the integration tests.

Effect

Most of the team members are fighting with deployments, where the service should run, how to setup environments, trying to write some deployments scrips and so on. There focus is not anymore on writing the business logic that shall run in the services themselves, but on the infrastructure part. They happens usually in a disorganized way, each person is looking for the same stuff, looking in the right place and many more.

Key People

In such teams, there is a high need of DevOps and people that need to think and prepare environment and how deployments will work before the development team start they job.

Solution

From the 0 day of the projects, you shall be aware that configuration and infrastructure part of such solution will be different from the other type of applications. You'll need people allocated on this part, that should support the team when they had problems.

The need of a scrips that allow development team to create the environment that they need is high and can be a time-saver.

Conclusion

In any projects, you shall never forget or neglect this kind of things.

Sharing is everything, but also specialization is important. Each member shall focus on the thing that they are the champions and you need champions for each item.

Why Database Modernization Matters for AI

When companies transition to the cloud, they typically begin with applications and virtual machines, which is often the easier part of the process. The actual complexity arises later when databases are moved. To save time and effort, cloud adoption is more of a cloud migration in an IaaS manner, fulfilling current, but not future needs. Even organisations that are already in the cloud find that their databases, although “migrated,” are not genuinely modernised. This disparity becomes particularly evident when they begin to explore AI technologies. Understanding Modernisation Beyond Migration Database modernisation is distinct from merely relocating an outdated database to Azure. It's about making your data layer ready for future needs, like automation, real-time analytics, and AI capabilities. AI needs high throughput, which can be achieved using native DB cloud capabilities. When your database runs in a traditional setup (even hosted in the cloud), in that case, you will enc...

How to audit an Azure Cosmos DB

In this post, we will talk about how we can audit an Azure Cosmos DB database. Before jumping into the problem let us define the business requirement: As an Administrator I want to be able to audit all changes that were done to specific collection inside my Azure Cosmos DB. The requirement is simple, but can be a little tricky to implement fully. First of all when you are using Azure Cosmos DB or any other storage solution there are 99% odds that you’ll have more than one system that writes data to it. This means that you have or not have control on the systems that are doing any create/update/delete operations. Solution 1: Diagnostic Logs Cosmos DB allows us activate diagnostics logs and stream the output a storage account for achieving to other systems like Event Hub or Log Analytics. This would allow us to have information related to who, when, what, response code and how the access operation to our Cosmos DB was done. Beside this there is a field that specifies what was th...

[Post Event] Azure AI Connect, March 2025

On March 13th, I had the opportunity to speak at Azure AI Connect about modern AI architectures. My session focused on the importance of modernizing cloud systems to efficiently handle the increasing payload generated by AI.
