IT Managers Important Points
The important points for IT managers in organizations and companies to
manage infrastructure services are:
● Easy to use
● Management tools & Optional web interfaces
● Easy to find skills and support
● Entry cost and maintenance, The lower the better
● Integration with other platforms
● Other points by you
OpenStack Pro/Cons
The advantage of OpenStack by our experiences at innfinision:
● The most successful Open Source project after Linux kernel
● Support from many OEMs and OS vendors
● Interoperability with many components, just pick your favorite one and plug it in
● Standard and well accepted APIs
The disadvantage of OpenStack by our experiences at innfinision:
● Very complex to setup and troubleshoot
● Although common code base, might differ from implementations
● Need high numbers of management nodes
● High skills required to run the cluster
VMware vCloud Pro/Cons
The advantage of VMware vCloud by our experiences at innfinision and
our customers advises:
● Feature rich (vSphere HA, vMotion, DRS, I/O control)
● Very large ecosystems
● All os vendors make it supported and certified under ESXi
● ESXi can be downloaded and used freely
The disadvantage of VMware vCloud by our experiences at innfinision and
our customers advises:
● Per core license - expensive
● Proprietary platform
● ESXi can not be APIs accessed - need to buy licenses
● Most of applications are based on Windows
OpenStack at a Glance
VMware vCloud at a Glance
Technical Compare
Hypervisor:
● OpenStack supports variants of hypervisor and container such as KVM, Xen, VMware ESXi, Microsoft Hyper-V, Citrix XEN, Docker, LXC
● VMware vCloud suppors ESXi as the only and default hypervisor
Customer and operations access :
● OpenStack native dashboard, 3rd parties dashboards, CLI
● VMware Windows clients, vCloud Director (EOL’d)
Storage:
● OpenStack Default non-persistent images. Pluggable Cinder:block volumes, Ceph, Several vendor SAN
● VMware VMFS over SAN and iSCSI
Network:
● Traditional switching and Software Defined Network
● VMware traditional switching infrastructure, SDN with additional products
Image management:
● OpenStack Glance Image Service, support all popular image formats
● VMware Catalogs & templates, OVF import
Management System:
● Nova (Cluster Controller)
● VMware vCenter
High Availability:
● Nova for VMs HA; OpenStack HA project for infrastructure components
● VMware vCenter Heartbeat
APIs:
● For OpenStack based on Open REST APIs, compatibility with Amazon EC2 & S3
● For VMware is Proprietary, mostly only under Perl and Powershell
Non-technical Compare
Costs:
● For OpenStack everything is free but Some might charge for a maintenance fee for enterprise support
● In VMware the costs contains License + Maintenance fee
Industries :
● OpenStack is for cloud management platform for large providers, carriers and large outsourcers
● VMware is for virtualization for enterprises
Skills:
● For OpenStack high-end skills required, including system and network
● For VMware, basic system administration is needed
Expansion :
● No actual limitation on OpenStack (might be handy create different Availability Zones)
● Max 32 physical nodes on VMware vCloud, though not recommended
Migration:
● OpenStack any to any through built-in qemu tools
● VMware converter for P2V and other virtualization formats
Flexibility:
● OpenStack primarily created for Linux, Windows supported on the same infrastructure
● Great guest OS support and large ecosystem on VMware vCloud
Who Should Use OpenStack ?
If you are a large company or ISP with hundreds of VMs and networks being destroyed and created daily and have budget of having more than 15 physical nodes to start, go for OpenStack
Who Should Use VMware ?
If you need certified traditional workloads (ex: Oracle, SAP, Microsoft Dynamics, ...) and you have money and also you want all the point-and-click features, this is a no-brainer decision go for VMware
