Khan Academy is a great supplement for things you already have learned, or as a mid-level course (versus a deep dive or high school/university level course). It is great for a paced learning environment if you want to casually refresh yourself on a subject or learn something new. I don't think this should be a replacement for structured learning, or if you struggle in self-paced learning environments. There have been times I would like to have been able to ask a professional (like an instructor) when struggling with a subtopic, which is possible in a classroom setting.
The team in charge of implementing Scality has to be full stack in order to guarantee the correct functioning of the entire system. However, you have to think very carefully about the balance between servers and disks, perhaps adopting smaller fully populated servers instead of large semi-populated servers, which would mean that over time our disk updates will not have a fully useful life.
As an organization, it took us a while to understand the shift from a traditional black box SAN to software-defined storage, but now we are much more certain of what this means. The time invested and the resources were not very high, thanks on the one hand to the technical support and on the other to the coherence and good development of the platform.
I've only had to seek support one time. There was a glitch in one of my lessons and I submitted an email. The glitch was fixed by support within a few days, but I would've liked for it to be faster. However, I don't have a big complaint there because it is a free service.
I personally found Khan Academy much better suited for adult learning of difficult or larger topics. Not so much for smaller changes that can be communicated via email. But it was more engaging and I found the information easier to digest. Change management can be tough but with the right tools it can be a breeze.
Due to the nature of our business we require extensive encryption and availability for sensitive customer data. The erasure encoding that Scality provides gives us the assurance that documents are rest are never in a state of being downloaded or available to a casual data thief. This is something that can be found with other vendors but at a fraction of the same cost. Having this kind of performance, availability and redundancy at the cost that Scality provides has made a large difference to our organization.
Keeping sensitive customer data secure is a must for our organization and Scality has great features to make this happen.
We replaced a single SAN with a Scality ring and found performance to improve as we store more and more customer data.
Being able to lose various portions of our Scality ring and allow it to continue to service customers while maintaining high performance has been key to our business.
