In the open source arena, the champion is OpenStack. The hybrid cloud, on the other hand, is the integration of a private cloud with a public cloud. This model involves the creation of <\/span><b>parallel environments<\/b><span style=\"font-weight: 400;\"> in which applications can be easily transferred between public and private Clouds.<\/span><\/p><p><span style=\"font-weight: 400;\">It can also mean leaving the company&#8217;s databases in its own on-site Data Center, and integrating them with public Cloud applications. During peak demand, <\/span><b>virtualized workloads<\/b><span style=\"font-weight: 400;\"> can also be replicated from <\/span><b>Data Centers<\/b><span style=\"font-weight: 400;\">.<\/span><\/p><p><span style=\"font-weight: 400;\">In a nutshell, a hybrid cloud is a mixture of public and private clouds. Part of the data may be stored on site, for example the most sensitive data, while the rest is stored on a remote public cloud server. This model is becoming increasingly popular with businesses, and currently dominates the cloud computing landscape.<\/span><\/p>\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-c3bd7ae elementor-widget__width-initial elementor-widget elementor-widget-video\" data-id=\"c3bd7ae\" data-element_type=\"widget\" data-settings=\"{&quot;youtube_url&quot;:&quot;https:\\\/\\\/www.youtube.com\\\/watch?v=i8lG5HGzMZ8&quot;,&quot;video_type&quot;:&quot;youtube&quot;,&quot;controls&quot;:&quot;yes&quot;}\" data-widget_type=\"video.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t<div class=\"elementor-wrapper elementor-open-inline\">\n\t\t\t<div class=\"elementor-video\"><\/div>\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t<div class=\"elementor-element elementor-element-527cf49 e-flex e-con-boxed e-con\" data-id=\"527cf49\" data-element_type=\"container\" data-settings=\"{&quot;content_width&quot;:&quot;boxed&quot;}\">\n\t\t\t\t\t<div class=\"e-con-inner\">\n\t\t\t\t<div class=\"elementor-element elementor-element-6b17dfc elementor-widget elementor-widget-heading\" data-id=\"6b17dfc\" data-element_type=\"widget\" data-widget_type=\"heading.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t<h3 class=\"elementor-heading-title elementor-size-default\">What is multi-cloud?\n<\/h3>\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-71b1869 elementor-widget elementor-widget-text-editor\" data-id=\"71b1869\" data-element_type=\"widget\" data-widget_type=\"text-editor.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t<p><span style=\"font-weight: 400;\">Within a company, a &#8220;multi-cloud&#8221; strategy simply means using more than <\/span><b>one public cloud service<\/b><span style=\"font-weight: 400;\">.
