El Modelo de Responsabilidad Compartida<\/span><\/h3><p data-path-to-node=\"4\">Este es el concepto m\u00e1s importante. En una casa propia, t\u00fa eres responsable de todo (el techo, la cerradura, la alarma). En la nube, las tareas se dividen:<\/p><ul data-path-to-node=\"5\"><li><p data-path-to-node=\"5,0,0\"><b data-path-to-node=\"5,0,0\" data-index-in-node=\"0\">El Proveedor (el due\u00f1o del edificio):<\/b> Se encarga de que la estructura sea s\u00f3lida, que haya c\u00e1maras en los pasillos, que los guardias en la entrada sean profesionales y que nadie entre por la fuerza al edificio f\u00edsico.<\/p><\/li><li><p data-path-to-node=\"5,1,0\"><b data-path-to-node=\"5,1,0\" data-index-in-node=\"0\">T\u00fa (el inquilino):<\/b> Eres responsable de ponerle llave a <b data-path-to-node=\"5,1,0\" data-index-in-node=\"55\">tu<\/b> puerta, de no darle copia de tus llaves a extra\u00f1os y de decidir qui\u00e9n puede entrar a tu sala.<\/p><\/li><\/ul><p data-path-to-node=\"6,0\"><span style=\"color: #ff9900;\"><b data-path-to-node=\"6,0\" data-index-in-node=\"0\">Regla de oro:<\/b> El proveedor protege la \u00abnube\u00bb, pero t\u00fa proteges lo que \u00abpones dentro\u00bb de ella.<\/span><\/p><hr data-path-to-node=\"7\" \/><h3 data-path-to-node=\"8\"><span style=\"color: #00ccff;\">2.
