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.

Windows Docker Containers can make WIN32 API calls, use COM and ASP.NET WebForms

After the last post , I received two interesting questions related to Docker and Windows. People were interested if we do Win32 API calls from a Docker container and if there is support for COM. WIN32 Support To test calls to WIN32 API, let’s try to populate SYSTEM_INFO class. [StructLayout(LayoutKind.Sequential)] public struct SYSTEM_INFO { public uint dwOemId; public uint dwPageSize; public uint lpMinimumApplicationAddress; public uint lpMaximumApplicationAddress; public uint dwActiveProcessorMask; public uint dwNumberOfProcessors; public uint dwProcessorType; public uint dwAllocationGranularity; public uint dwProcessorLevel; public uint dwProcessorRevision; } ... [DllImport("kernel32")] static extern void GetSystemInfo(ref SYSTEM_INFO pSI); ... SYSTEM_INFO pSI = new SYSTEM_INFO(

ADO.NET provider with invariant name 'System.Data.SqlClient' could not be loaded

Today blog post will be started with the following error when running DB tests on the CI machine: threw exception: System.InvalidOperationException: The Entity Framework provider type 'System.Data.Entity.SqlServer.SqlProviderServices, EntityFramework.SqlServer' registered in the application config file for the ADO.NET provider with invariant name 'System.Data.SqlClient' could not be loaded.

See http://go.microsoft.com/fwlink/?LinkId=260882 for more information. at System.Data.Entity.Infrastructure.DependencyResolution.ProviderServicesFactory.GetInstance(String providerTypeName, String providerInvariantName) This error happened only on the Continuous Integration machine. On the devs machines, everything has fine. The classic problem – on my machine it’s working. The CI has the following configuration: TeamCity .NET 4.51 EF 6.0.2 VS2013 It see

Navigating Cloud Strategy after Azure Central US Region Outage

 Looking back, July 19, 2024, was challenging for customers using Microsoft Azure or Windows machines. Two major outages affected customers using CrowdStrike Falcon or Microsoft Azure computation resources in the Central US. These two outages affected many people and put many businesses on pause for a few hours or even days. The overlap of these two issues was a nightmare for travellers. In addition to blue screens in the airport terminals, they could not get additional information from the airport website, airline personnel, or the support line because they were affected by the outage in the Central US region or the CrowdStrike outage.   But what happened in reality? A faulty CrowdStrike update affected Windows computers globally, from airports and healthcare to small businesses, affecting over 8.5m computers. Even if the Falson Sensor software defect was identified and a fix deployed shortly after, the recovery took longer. In parallel with CrowdStrike, Microsoft provided a too
