Private cloud, has there?

Good day dear abrowser!

The issue is long overdue, but I want to put everything on the shelves. I have lab tested and debugged design private clouds with cool buns — decentralized storage, high availability of virtuallock, easy maintenance, open source and sane roadmap developers and, if necessary, their direct readiness support.

And the question incredibly simple, but necessary for your opinion — in your opinion, where and when private virtualization platform wins compared to public cloud providers by type Amazon.

Solution
1) privacy (but there is a threat of a mask-show)
2) channel up to the next room faster channel to the data center in America
3) large dependence on qualification of the administrator. if the admin advanced is a good thing. if not — then bad.
Oh, 3rd paragraph, it's just the lords of the sea )) But if you create a sane documentation and conduct live training of the person because the most important is the method of teaching and what to teach.
Thanks for the reply! - adelbert14 commented on October 3rd 19 at 03:46
documentation plan to lay out in open access? - Maurice_Streich commented on October 3rd 19 at 03:49
For each embedded project I think to prepare detailed supporting documentation unprecedented format) But it still will reflect the confidential info of a customer — specific architecture, appearance, etc. So, no. Oh and don't forget about the live training, open I way — time will tell)) - adelbert14 commented on October 3rd 19 at 03:52

Solution
To use a private cloud requires two conditions:
1) high demands for resources in the normal mode;
2) the presence of at least two components, the bursts of activity which do not overlap in time.

In violation of the first condition, the project goes to public clouds, breach the second private cloud loses a normal failover cluster.
Well, and is one of the cornerstones is not actually the notorious "privacy" when you want to observe a certain level of paranoia, not trusting others iron/admins/etc.? - adelbert14 commented on October 3rd 19 at 03:48
Well, paranoia can replace the first condition. But not the second.

In addition, the paranoia, the thing is often expensive. I estimate the prices of the online channel set to SLA, so once again begin to trust the Google drive... - Maurice_Streich commented on October 3rd 19 at 03:51
:) Everything is relative, that is, of course, everything should be weighed. Thanks for your answer! - adelbert14 commented on October 3rd 19 at 03:54

In my case, private virtualization allows you to keep all the problems under control backups on disk which I can take up, the access from the network of this quality which is necessary, access to iron (and iron is still non-standard should be used, like dedicated phone lines). The alternative is third-party clouds, but as soon as you look at the price tag and the lack of real guarantees and reliability — a desire to move to the cloud is lost. This (reliability) applies not Amazon, of course, but about him and not talking, I guess. Well, there are laws that do not allow some things to give to your uncle.

I design for myself virtualization, but it is difficult, and may be debugged the platform would be in demand.
Thanks for the reply! About the debugged platform — ready to show his creation, I am sure I will surprise You. - adelbert14 commented on October 3rd 19 at 03:50
Maybe there is a description on the Internet? - Maurice_Streich commented on October 3rd 19 at 03:53

She wins only in privacy, the rest loses, in fact the privacy is the main reason for private clouds, well, sometimes another is the importance of the response to milliseconds.
Well, that's what You mean by "privacy", can you describe please? This is the essence of the question) - adelbert14 commented on October 3rd 19 at 03:52
understand that no one except me in the cloud has access to the data.
banks for example can't afford to be hosted in the public cloud, and suddenly the Amazon database will merge into the public. - Maurice_Streich commented on October 3rd 19 at 03:55
Not only privacy. Now I have this private cloud is in the next room, and the employees of our organization not depend on the vagaries of the Internet service provider. - adelbert14 commented on October 3rd 19 at 03:58
Well, that would be local problems, but to solve them so I think it is not appropriate.
And your customers how to get the data from the cloud if you don't have Internet?
The company which is outside of the cloud does not give data, I wouldn't call the standard case of the cloud, as a result of accessibility to the outside world is not.
And companies that decided to move from Amazon to its cloud, the fall of the Internet in the office I have not met. - adelbert14 commented on October 3rd 19 at 04:01

As far as I understand cloud computing, storage system data based on the search of duplicates and specify the index on them instead of real file storage. (Roughly speaking, if 10 users have downloaded the same file, then the file will be stored in one place, and nine will remain links), to avoid excessive redundancy.
How to ensure privacy? Encryption. Good encryption means that when you re-encrypt the same file, the hash is encrypted "copies" will be different. Thus, it is not consistent with the idea of getting rid of redundancy. The cloud is extremely expensive and resource intensive.
You wrote a comment about cloud-based file storage, and the question was about the cloud VDS. In addition, you misunderstood the term "private cloud". - adelbert14 commented on October 3rd 19 at 03:54
IrkDesigner, You have described one of the many key features allowing to "save" the investment in storage — de-duplication, and it's a really cool thing. But as already noted mayorovp, here it is about platform virtual machines (VDS if you like) but on its capacity, on his/renting the hardware, you know? - Maurice_Streich commented on October 3rd 19 at 03:57
