Private Cloud, Ubuntu, KVM and Open vSwitch: The Most Sought-after Technologies in OpenStack - Report

By CIOReview | Thursday, November 27, 2014

FREMONT, CA: In order to gain insights into the implementation trends of OpenStack solutions by organizations in their various stages of development and deployment, OpenStack Foundation and User Committee has come up with the latest survey whose results have now been made available. Moor Insights & Strategy, an independent research firm, played key role in conducting the survey to which OpenStack operators and application developers responded.

The report is based on the feedback updated during the time period of 20 February 2014 to October 2014.

Salient features of the report are below:

  • Production deployment over the last six months has seen a jump of 13 percent (from 33 percent to 46 percent between May 2014 to November 2014)
  • Private cloud adoption holds greater momentum as 45 percent of OpenStack users prefer On-premise private cloud and another 25 percent of them implement hosted private cloud environment.
  • Public cloud adoption remains just below 20 percent (19 percent)
  • Other forms of cloud such as hybrid cloud stands at 3 percent in production environment; community cloud is being used by 5 percent of the OpenStack users
  • Industry wise – IT industry continues to lead the pack – at 16 percent –as the sector with most OpenStack implementations followed by Telecom (10 percent), Government and Finance (2 percent.)
  • Country wise U.S. continues its sole leadership beating the rest of the nations handsomely in the largest consumer of OpenStack technology at 46 percent (of those surveyed in U.S. region acknowledging OpenStack deployment.) The second in the list is Japan, U.K, and India standing way behind U.S. with OpenStack solutions adoption of just 5 percent.
  • Major Drivers for OpenStack adoption – innovation, open technology, cost savings, freedom from vendor lock-in, efficiency, flexibility, time-to-market, greater talent, control are key factors for OpenStack adoption.

With respect to the technology aspects of OpenStack infrastructure, adoption levels of available OpenStack features are discussed below:

OpenStack versions: Havana (2013.2) finds the largest implementation with 45 percent of OpenStack users (who responded to the survey) having deployed it in their cloud environments. Next only to Havana is Icehouse (201431) with 37 percent acceptance.

OpenStack Projects: OpenStack Compute (Nova) is being used the most by the users followed by other services such as Openstack Identity Service (Keystone), OpenStack Image Service (Glance), OpenStack Block Storage (Cinder), OpenStack Network (Neutron), OpenStack Object Storage (Swift), and more.  OpenStack Bare Metal (Ironic) forms the bottom of the projects list of usage.

Web Services: Web services are the maximum deployed services – with 57 percent of workload – in OpenStack followed by database services at 49 percent and QA/Test services at 40 percent.

Hypervisors for Computing: Kernel-based Virtual Machine (KVM) holds its position as the widely deployed hypervisor with OpenStack across all deployment types, followed by QEMU, ESX, and Bare Metal, and Docker.

Block Storage Drivers: Ceph RBD is the most preferred Block Storage Drivers, followed by LVM (default), and GlusterFS, NFS, NetApp, and EMC.  

Network Drivers: Open vSwitch is the most sought after network driver leaving behind nova-network, Linux Bridge, Modular Layer 2 Plugin (ML2), and Cisco UCS/Nexus.

Operating Systems: 64 percent of OpenStack users prefer Ubuntu operating system followed by CentOS used by 19 percent of those who responded. Red Hat Enterprise Linux meanwhile was mentioned by 20 percent of the other respondents in the survey.

Database: MySQL tops the list, followed by MariaDB, MySQL with Galera, MongoDB and more.

31 percent of the respondents in the User Survey of OpenStack said they interact with Amazon Web Services (AWS) while working with OpenStack.
