Azure Price estimation - what you need to take into account

Calculating the cost consumption for a solution that runs in cloud can be sometimes challenging. First of all you need do a forecast of how many resources are required and secondly you need to put on the paper all things that are billable by the cloud provider.

Azure Price Calculator
The pricing calculator offered by Microsoft for Azure is a nice tool, that helps you to take into account all the items. It is able to persist the cost even if you close the tab and when you are done you can export it to an excel file. For basic estimations is good, but I expect that you'll end up pretty fast with a complex excel.


Excel Calculator
In the last few years, I was involved at least 2 time per month in Azure consumption estimations for different projects - from the small one that consume a few hundreds of euros per month to big ones where you end up with a bill that has six or seven figures per year. 
You'll find different templates on the internet that you can use and don't be surprise if you end up creating your own template.

Tips and Tricks
I have a list of items that I take into account when I do price estimations for Azure. It doesn't covers everything, some things I ignore and other I consider them by default added them to the cost estimations. It's only a checklist for me, that I decided to share with others.

Things to consider
General
  1. Special support from Azure (premier support)
  2. In general computation is the main driver cost, but don't be surprised is traffic will also be around 20-30% of your cost, especially in IoT era
  3. Development, integration, testing environment also cost money, deallocate them when you don't use them
  4. Development, integration, testing environment don't need to run at full capacity
  5.  Select the right tire - to big is just waste of money
  6. Change the tier based on your needs (not only VMs, also SQL tier)
Computation
  1. VMs disk are not included in VM price and needs to be included in estimations. You pay only what you use
  2. Outbound traffic from VM
  3. The minimal number of VMs of computation units is 2, never 1
  4. Scale down when you don't need all the power

Storage
  1. Outbound traffic for Azure Storage (blobs, Azure Table)
  2. Outbound traffic when you do a sync between two different Azure Regions (storage, DB, ...)
  3. Storage cost for backups
  4. Cost of transactions, especially on Azure Tables
  5. Size of the logs
  6. Use CDNs as much as possible
  7. Non-critical use cases can implement a back-off mechanism for cost optimization (reduce number of transactions)
DB
  1. Storage cost of SQL Azure backup
Messaging
  1. Outbound traffic for Service Bus, Event Hub and other messaging system
  2. Number of events price for Event Hub
  3. Number of messages for Service Bus
Azure AD
  1. Number of users 
  2. Multi-factor authentication
  3. Number of applications
Service Fabric
  1. Minimum number of VMs in cluster (is not 2)

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.
