Azure Redis Cache becomes more powerful with new features

There were a set of updates related to Azure Redis Cache last days.

If you didn't had the opportunity to use Redis Cache until now, you should know that it is a in-memory data structure stores that is used very often not only as a database or a cache, but also as a message broker. It is fully with features that can make  your life easier.
Microsoft is offering this feature as a out of the box service, that you can use it from the 1st moment, no configuration or installations needed.

Some new features are now appearing in Public Preview, that will make Azure Redis Cache more appealing to anybody.

Azure Redis Cache Clustering
Until now we didn't had to many options on Azure Redis Cache if we wanted more power from it or if we would reach the size limit of an instance.
Now, in the moment when we create a new instance of Azure Redis Cache we have the ability to activate this feature and specify the number of instances that we need. Don't forget that each instance (shard) from the cluster is in a primary&replica pair. The replicas are managed by Azure Redis Cache Service our of the box.

Don't forget that this feature can be activated only for new instances of Azure Redis Cache.
In this moment the maximum size of a shard is 53GB, combined with the size cluster that can reach 10. This means that you can have a Azure Redis Cache Cluster that has 530GB  ... WOW ...

Azure Redis Cache Data Persistence
How nice would be to be able to create backups and persistent your data from Redis Cache and to be able to access/restore it later on.
Even if it is a cache, you might need to be able to persist the data in case of a disaster. The persistence is done on Azure Storage and can be later used.

Azure Redis Cache LOVES Azure Virtual Network
Starting from now we can add our instances of Azure Redis Cache to Azure Virtual Networks (VNet). In this way we can isolate our instances of Azure Redis Cache from the public word.
By having the cache in VNet would guaranty you that nobody from outside the VNet can access it, if it doesn't has access to VNet.
This can be translated as an additional security layer at network level.

Conclusion
The new features that were just announced now for Azure Redis Cache makes this service very powerful and can be used with success for complex scenarios where the size of cache can be very big and requires to be isolated from public internet.

How to check in AngularJS if a service was register or not

There are cases when you need to check in a service or a controller was register in AngularJS.
For example a valid use case is when you have the same implementation running on multiple application. In this case, you may want to intercept the HTTP provider and add a custom step there. This step don’t needs to run on all the application, only in the one where the service exist and register.
A solution for this case would be to have a flag in the configuration that specify this. In the core you would have an IF that would check the value of this flag.
Another solution is to check if a specific service was register in AngularJS or not. If the service was register that you would execute your own logic.
To check if a service was register or not in AngularJS container you need to call the ‘has’ method of ‘inhector’. It will return TRUE if the service was register.
if ($injector.has('httpInterceptorService')) { $httpProvider.interceptors.push('httpInterceptorService&#…

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. Make sure that the assembly-qualified name is used and that the assembly is available to the running application. 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:

[Post-Event] Codecamp Conference Cluj-Napoca - Nov 19, 2016

Last day I was invited to another Codecamp Conference, that took place in Cluj-Napoca. Like other Codecamp Conferences, the event was very big, with more than 1.000 participants and 70 sessions. There were 10 tracks in parallel, so it was pretty hard to decide at  what session you want to join.
It was great to join this conference and I hope that you discovered something new during the conference.
At this event I talked about Azure IoT Hub and how we can use it to connect devices from the field. I had a lot of demos using Raspberry PI 3 and Simplelink SensorTag. Most of the samples were written in C++ and Node.JS and people were impressed that even if we are using Microsoft technologies, we are not limited to C# and .NET. World and Microsoft are changing so fast. Just looking and Azure IoT Hub and new features that were launched and I'm pressed (Jobs, Methods, Device Twin).
On backend my demos covered Stream Analytics, Event Hub, Azure Object Storage and DocumentDB.
