Suse Linux i̇le SAP Hana felaket kurtarma ve otomati̇k yük devri̇ çözümleri̇

Description
SAP HANA sistemleri arasında otomatik yük devretme (dikey ve yatay mimariler) senaryoları otomatik olarak ikincil sistemde yük devri ve kullanıcı etkisinin azaltılması ile herhangi bir durumda sistem yöneticisi aksiyonu gerektirmeyen ve insan hatalarının azaltıldığı çözümler anlatılacaktır. Ayrıca farklı büyüme senaryoları (performans optimize, maliyet optimize, çok katmanlı, çoklu kullanım, yatay genişletilmiş) için geliştirilmiş çözümlere değinilecektir.
