Case study & RESULTS

IS PERFORMANCE CRITICAL?

Directly impacted …

…95% Private cloud fails due to wrong strategy & poorly planned optimization– www.Gartner.com

…Decline in performance testing for cloud based virtual environment as compared to percentage from previous year– World Quality Report 2016-17

…Statistics increased to 49% for not testing applications in cloud environment hence failing to realize importance P2V migration– World Quality Report 2016-17

CASE STUDY

CASE STUDY - CONCLUSIONS VMWare ESXi 5.0 showed issue with time sync.

Upgrade resulted Time Drift of 0.001126 PPM as compared to physical machine 0.002984 PPM.

Service migration (HA/BCP) Monitoring showed spike in CPU due to Open SIP & increased time(~1000%) to stabilize connections.

Resource contention to simulate Multi-Guestingtriggered failover. Separate hardware recommended for standby server.

Attaching Virtual Hardware CD-ROM drive degraded performance of VM.

IN NUTSHELL

Know your APPLICATION.

PREPARE for challenges.

Evaluate PROS & CONS of Virtualization w.r.t PERFORMANCE.

BENCHMARK to compare PHYSICAL & VIRTUAL.

OPTIMIZE your INFRASTRUCTURE through intelligent testing.

KEY TO ENSURE PERFORMANCE IS TIMESTAMPING in P2V.
