Windows Azure Storage performance benchmark and options

cstJust recently I had to assign a new virtual machine for yet another project, and this presented a perfect opportunity to try the recently introduced feature of Azure storage – the SSD drives.

As you know (and if you don’t – you can read about it here), the type of memory used in SSD drives provides not only faster way to write and read data, but more importantly – to read non-sequential data, hence promising a better performance for database and web caching. But, of course, I had to test it before putting any eggs into that basket.

One thing that raised some suspicion was the IOPS limit mentioned in each virtual machine “size” chart. The “size” of virtual machine, in Azure jargon, is the specs. Usually the name of the “size” consists of the literal and a cipher. The first tells us about the purpose of the machine and the second – how powerful and expensive it is.

I’ve selected the virtual machine that had “SSD 7Gb” on it, wondering what it means. Turned out that it means that you’ll get the temporary drive (the one with contents wiped time after time) with total size of 7Gb, but part of it will be taken by the virtual memory file. Still, you’ll get over 5Gb left and I never needed even that much on a temporary drive. More...


How Google Stole My App

ipt2A lesson for mobile developers.

When you steal from IT corporation, it’s a theft. When corporation steals from you – it’s a progress.

You may live through an event in your life, when stars align and you discover a new niche, where you would be a pioneer. Get the moment of enlightenment, hectically lookup the Internet for solutions and be amazed that no one else did that. You would actually be the first. And there is no guarantee, that it will be success – in a heap of millions of apps and websites and info-noise of events, things are missed. In Android alone, there are 2.8 millions of apps today, and it’s still growing.

Indie projects are akin to live creatures – born in a coincidence that looks like a miracle, they start small and weak, just like most creatures on our planet – and they don’t look like what they will in a few months from now. At that time they are easiest to snatch by all sorts of predators and the nature.
