[Post Event] ISTA Conference 2015, November 18-19, Sofia Bulgaria

This week I had the great opportunity to be one of the speakers of ISTA Conference. This was the 5th edition of ISTA Conference and it seems that every year ISTA Conference becomes not only bigger and bigger but also the quality of the session is higher and higher.
This year there were more than 30 speakers from 3 different continents, 2 keynotes, more than 26 sessions, 4 tracks in parallel and a full day of workshops. On top of this all tickets were sold out. Great job!

From my point of view, it was one of the best organized conferences. All the events went very smoothly, all the time internet connection was working, you were able to find enough water and coffee and during the lunch break there was enough food for everyone. This small thing makes a big difference. On top of this, the local speakers presented all their sessions in English, in the end all speakers were able to join and understand all the sessions.

At this conference I talked about cloud and how we should design a system that can scale over the boundary of a cloud provider. You know, even if you are using cloud, this doesn’t mean that you have no limitations. Each service has his own limits and you need to know how to handle the situations when this limits are hit.
Below you can find the slides from my session.



See you next year.

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(

Azure AD and AWS Cognito side-by-side

In the last few weeks, I was involved in multiple opportunities on Microsoft Azure and Amazon, where we had to analyse AWS Cognito, Azure AD and other solutions that are available on the market. I decided to consolidate in one post all features and differences that I identified for both of them that we should need to take into account. Take into account that Azure AD is an identity and access management services well integrated with Microsoft stack. In comparison, AWS Cognito is just a user sign-up, sign-in and access control and nothing more. The focus is not on the main features, is more on small things that can make a difference when you want to decide where we want to store and manage our users.  This information might be useful in the future when we need to decide where we want to keep and manage our users.  Feature Azure AD (B2C, B2C) AWS Cognito Access token lifetime Default 1h – the value is configurable 1h – cannot be modified

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.
