32. 7 Key Points to Take Home
• Datacenter consolidation is driving remote users to access SAP applications
over the Web
• Web access requires tighter security, reducing latency and providing high
availability for mission critical SAP applications
• Two ways of addressing these challenges using ADCs – Asymmetric and
symmetric
• Asymmetric deployment addresses challenges of availability, security, and
latency and delivers performance and improves ROI by offloading from SAP
servers
• Symmetric acceleration utilizes integration with SAP AccAD to deliver high
performance over WAN
• Ensure your ADC supports your virtualization environment, management tools,
and integrates with ASLR for automation
• Make sure that the ADC technologies you utilize and deploy are certified by
SAP
