Microsoft Azure's popularity is growing especially in the small and mid sized markets. Pay-as-you-go and the 0 investment makes these companies consider moving to the cloud attractive. Microsoft engineers working in Azure guarantee a SLA of 99.9 % or more (depending on the type of business).  The easiness of building infrastructures in Azure introduces a problem that has not been there before when IT was incorporated in the organisation: budget management. Before you had these endless and boring meetings about budget and spendings with the internal accountants to get a go and every dime was turned twice of not three times before a go was given.  In Azure you can command a server that is capable to perform at 2000 DTU and it will cost you € 31.370,76 per month . Oeps! No kidding! "Sorry, I was just looking for something powerful" the developer smiled nervously in the meeting after the reception of the Azure invoice. But everybody will starts really screaming if t...

One of the new options in SQL Server 2016 is to store cold data in Microsoft Azure. The idea behind it is that doing so could be far less expensive than storing the data locally. It sounds great but the reality is a bit different. in this blog post I will share my experiences with this feature.   Stretch database or the first steps versus "Distributed database" Looking closer at the feature of Stretch Database it incorporates actually the separation of data in a table over multiple servers. There is a main server and a back-end server that both contain a part of the data in your table. The back end server has currently to be in the Azure cloud. The front end can be in the Azure cloud to. When a query is fired on the table both front end and back end servers work together to get the data.  The MSDN Library shares an interesting picture: What this picture shows is that in the Azure cloud a SQL Server Database is created that stores all or a part of the cold data. The da...

I have been quiet busy getting my certifications for my Microsoft vTSP and P-Seller membership. What helped me enormously is the information available in the Microsoft organisation. Microsoft colleagues are struggling with the same problems and have to be certified like all of us.  Unfortunately Microsoft Corporation has decided that the vTSP / P-Sellers will no longer be part of the Microsoft organisation by the end of this month. That will certainly make the front runner job as a P-Seller / vTSP more complicated.  So this blogpost is a bit of goodbye to my Microsoft integration.  It was great because I had direct contact to Microsoft colleagues like Ned Pyle, Ryan Sokolowski, Conor Cunningham, Henk van der Valk, Brian Smith, Chris Buehler, Michael Rys, Vivek Gupta and others. It was a privilege to work with you all.    Since Satya Nadella has become CEO of Microsoft a wind of change has taken over Microsoft. Away is the arrogance and the "we are the be...

I am on Facebook because everybody is there. From friends to people who share the same hobbies and interests, they are all there. I tried Google Plus for a while because it is technically superior to Facebook and does not have any build in commercials (but of cause that can change over night).  The thing is Google Plus does not evolute. It is like Apple: this is what you get and after a few years it just starts to bore. I can not understand people that are still confident with their 10 years old icons ordered in the same way for 10 years. It must be for all people who do not understand the basics of information technology: evolution and sometimes even revolution. For Apple it worked out with their 17% global market share, for Google Plus it did not because it is almost gone. I am just waiting for Google to shut it down. So I move to Facebook. On great thing about Facebook is that they have the like button. People can visit your page and say what they think about it or give comm...
