The whole thing was previously embedded by\u00a0us on\u00a0Azure VMs, which provided us with stability, ease of scalability, and access to\u00a0the latest versions of the software. As\u00a0the business grew, the amount of data available for analysis increased. It was no\u00a0longer just sales data, but also full information about a\u00a0product, stock, inventory level, customers (and all about them), suppliers, etc.<\/p>\n<p id=\"637e\" class=\"pw-post-body-paragraph kj kk iy kl b km kn ko kp kq kr ks kt ku kv kw kx ky kz la lb lc ld le lf lg ir ga\" data-selectable-paragraph=\"\">This amount of data increased every day and new reports came along with it. The use of virtual machines in\u00a0Microsoft cloud services made it easy to\u00a0upgrade available resources.

This allowed us to\u00a0stop importing raw data into the \u201ccubes\u201d themselves.

This allows the customer to\u00a0decide when more resources should be\u00a0made available to\u00a0operators (recurring report generation, daily analytics). The client can also decide at\u00a0what time the power is available for data load or\u00a0refresh.<\/p>\n<p id=\"0a46\" class=\"pw-post-body-paragraph kj kk iy kl b km kn ko kp kq kr ks kt ku kv kw kx ky kz la lb lc ld le lf lg ir ga\" data-selectable-paragraph=\"\">The result of this project is to\u00a0expand structures with new resources, increase data availability for analysts and business users while keeping costs at\u00a0a\u00a0similar level.<\/p>\n<p id=\"d1a6\" class=\"pw-post-body-paragraph kj kk iy kl b km kn ko kp kq kr ks kt ku kv kw kx ky kz la lb lc ld le lf lg ir ga\" data-selectable-paragraph=\"\">End users noticed the biggest difference after implementing new Azure solutions.
