For fast and stable work of CMS Magento 2 (and also previous versions) it is required a powerful processor and a lot of random access memory (RAM). Magento 2 can work on standard hosting but when your shop is fullfilled with goods and the clients of the shop start visiting the site, it will be working slowlier and slowlier. Therefore especially for Magento 2 we have created a line of tariff plans especially for which servers have been configured and adjusted, considering requirements of the developer.
