Redefinition of Business Continuity Strategies using Cloud Native Enterprise Architectures Frank Stienhans, CTO August 2016

Abstract Both production and non-production landscapes are massively effected by the rewritten laws of physics in the cloud. One opportunity of Cloud Native Enterprise Architectures is to redefine the approaches to Business Continuity and Disaster Recovery. Using SAP workloads on AWS as example we will show how and why enterprises run different than before and how Disaster Recovery needs accelerate all in migrations to the cloud.

Cloud Transformation Before and After Using the example of SAP HANA on Amazon Web Services

Provisioning Time: Infrastructure, Installation, Configuration SAP HANA Appliance 14 Weeks Ocean9 + AWS 15 minutes 0.01 % 9400 times faster

Scale Out Time: Infrastructure, Installation, Configuration SAP HANA Appliance 14 Weeks Ocean9 + AWS 4 minutes 0.003 % 35000 times faster

Hardware Refresh Time: Infrastructure, Installation, Migration SAP HANA Appliance 18 Weeks Ocean9 + AWS 60 minutes 0.03 % 3000 times faster

Upfront Cost for Provisioning, Scale out, Hardware refresh SAP HANA Appliance $ XX,XXX Ocean9 + AWS $ 0

Be Prepared for Hardware Failure SAP HANA Standby Nodes $ XX,XXX Ocean9 + AWS EC2 Auto Recovery $ 0.50

Cloud Sizing: Application Servers (SAP and beyond) On Premise Cloud Few Large Servers Many Smaller Servers Auto Scaling + High Availability Static Servers

Enterprise Elasticity – A Year, A week, A day Static Sizing Cost Saving Average

Cloud Sizing: SAP Database On Premise Cloud One Large Server Large Server Static Server Scale Up in 1 hour

High Availability and Disaster Recovery

SAP HANA Multi-Site High Availability Run SAP HANA in 2 or 3 Availability Zones to achieve an uptime of up to 99.99% Do not fail back to something that failed once. Analyze the error and terminate the faulty System Site.

Presenter: Frank Stienhans, CTO Frank is an early cloud innovator with key architecture and operations contributions. In 2007, he was first to recognize the power of AWS for SAP use cases: His team build a self service SAP on AWS, serving more than 1000 employees with more than 11000 servers per month. Gaining tremendous operational expertise, SAP’s former CTO Vishal Sikka challenged Frank to demonstrate SAP HANA scalable performance with 1000 CPU cores, which were delivered as a SAP HANA aggregated system with 111 cloud machines. In 2013 Frank joined AWS Professional Services to build up the SAP Practice. He rolled out the first SAP HANA Production System in an Enterprise on AWS and many more since. Frank advised dozens of large global enterprises around the world on the best strategy, architecture and operations for SAP on AWS. At Ocean9, Frank’s team is continuously raising the bar for what is possible for Enterprise Solution Deployments and is passionate about assisting partners and customers in their journey to and in the cloud. Frank is considered the leading expert in his field and is the holder of 18 cloud related patents. © Copyright, 2016, Ocean9, Inc., All Rights Reserved
