Comparison between VMware and Open Stack Cloud Comparison between VMware and Open Stack Cloud Document Transcript

  • Summary of Comparison between VMware and Open Stack Cloud Differentiation and service explanation Prepared by Cloud R&D Panacea Systems Limited 8/19/2013 Panacea Systems Limited Dhaka, Bangladesh

Summary of Comparison between VMware and Open Stack Cloud Services VMware Features Open Stack Features Live Migration vMotion KVM Live Migration Resource Scheduler DRS Nova Scheduler Storage motion & support SDRS Nova Scheduler Network Security vShield Nova-network service Network Management vDS Quantum/Nova-network service Storage Management Storage APIs Nova-volume service Live Migration  Live migration in VMware managed by vMotion. Metro vMotion allows migration over metro level networks (up to 10 ms RTT) by dynamically adjusting TCP buffer.  Live migration in Open Stack managed by Kernel-based Virtual Machine (KVM). Migration using KVM supported libvirt block migration features. Resource Scheduler  VMware Manages workload by grouping virtual machines; pooling resources of physical hosts and prioritizing VMs in these pools.  Open Stack manages the resource workload ‘intelligently’ by using Nova Scheduler Storage motion & support  VMware allows moving volume storage workloads over datastore cluster Storage vMotion. Supports affinity/anti-affinity rules.

Nova-scheduler supports boot from-volume feature that allows to use iSCSI persistent volume as boot VM device. Network Security  In VMware, Zones component provides IP-based applic.-aware statefulfirewall that recognizes IP addresses, ports, protocol (5-tuple), application type. Edge component provides connection on network edge, including 5-tuple firewall, NAT, DHCP server for VMs, site-to-site IPSecVPN, simple load balancing.  Open Stack supports per-VM firewall that uses 5-tuple to policy network access Security Groups Network controller performs edge firewall, DHCP, DNS, NAT functions for VMs   Cloud-pipe allows VPN connection to VMs (OpenVPN) Opensource IDS/IPS can be integrated into network controller. Network Management  In VMware, nnd-to-end physical and virtual network are managed Cisco Nexus 1000V. Enables Net IO Control.  In Open Stack end-to-end physical and virtual network management in Quantum following plug-in: o  Cisco Nexus 1000V o  Nicira virtual switch o  Open vSwitch o  Linux bridges Storage Management  VMware allows to integrate storage solution management vCenter for management functionality which called VASA.  Open Stack allows utilization of back-end storage appliance advanced features of driver configuration, including CoW, thin provisioning; no API provided by OpenStack.
