Cloud economy

    Dear Khabrovites!

    So the long May holidays ended. To enter the operating mode, we suggest that you count a little.

    Everyone who was interested in cloud computing might have noticed that on the Internet they often talk about the benefits of using clouds, but very rarely detailed examples with calculations are shown.
    We decided to reduce the existing gap and offer you to calculate the benefits of the clouds with us under the cut.

    Before proceeding with the calculations, let's figure out why there are so few similar examples with preliminary calculations on the Internet. The answer is actually simple - a large number of possible scenarios. To make an averaged, universal calculation is an extremely difficult and unnecessary task.

    For this reason, we calculate the benefits for a certain virtual company, previously limiting it, as in school tasks, to conditions.

    Consider that:
    • the used hardware and software lose their relevance over time or their life spans. The current update standard is a period of time every three years, we take this period for the main time calculation period;
    • “standard” company, that is, employees perform the functions: work with documents, correspondence by mail, preparation of financial documents (using 1C), communication via Skype, printing and scanning of papers, etc .;
    • Employees work in the office.

    We will not take into account in the calculations:
    force majeure situations for the traditional model of IT infrastructure, to evaluate intangible factors (time, nerves and risks), expenses on the Internet and consumables, property tax and VAT offset.

    In comparison, for comparison, two models will be involved, “all in the office” and “all in the cloud”.
    Hybrid usage patterns are possible, but they, unfortunately, do not provide a transparent picture. For this reason, we will not consider them.

    Prices for the cloud model and for the traditional one were taken from various open sources (see the end).

    So, the company employs 50 people. The requirements for fault tolerance and security are average.

    Expense table

    It should be noted that the cost of using licenses in the cloud is higher, but this has its advantages. You can easily change the number of licensed copies and use only the latest software.

    Separately, we note the line "money costs money." In this paragraph, we took into account that when using the cloud scenario, you do not need to spend the entire allocated budget, and it can be used in business, or put on deposit. The average yield is 6% per annum, the effective rate is 3% per annum of the total.

    Now consider the exact same company, but with branches. For example, take five branches of 10 people each. We will not duplicate information from the previous calculation.

    Expense table

    Given the branches, the situation has changed somewhat, compared with the first example. Although servicing each branch is cheaper, but considering that you need to service five different points, it will cost the company more. Serving all branches at one point (cloud) is more economically attractive.
    As can be seen from the resulting calculations for our virtual company with the selected conditions, the use of the cloud model is noticeably more profitable, especially considering the branches.

    We note separately that in no case did we claim universality in our calculations, for specific situations we need our own calculations.

    In any case, thanks for counting with us!
    We hope you were interested :)
