what is the best stack for your next project

People quite often asking me about technology stack, and where to go with next big project. The answer isn’t simple – it depends.

Amazon is super simple, and developer friendly – Google… well not so easy. So the questions – why you may consider using GS instead of well documented, and super easy S3. Not many people realise but Google Cloud Storage is actually cheaper . The other reason to use Google Storage is having different provider as a backup solution.

MongoDB vs MySQL using golang

MongoDB vs MySQL using golang

I’m the guy who like to test. Benchmark is my… middle name. You can find dozens articles about speed one or other solution. I mean MongoDB and MySQL . I tried MongoDB couple times, and each time I wasn’t  moved by it speed. Got project coming in, when I have to deal with large amount of concurrent connection. It’s not very big, but bigger then casual MySQL load.

So… how did I test – very dump way. Got 2 tables, one around 11k records, second one close to 200k record. Not much. Fields were indexed in both MySQL and MongoDB. And then i run benchmarks. First one had string fields, second one numeric.
