What’s new in OpenStack Juno?

Posted on November 11, 2014 by Sangram Rath | Comments(0)

  OpenStack Juno is now generally available. This is the 10th release of the most popular and hot Private Cloud offering out there. Here is a sneak peak into what’s in store in Juno. Network Function Virtualization (NFV) It is one of the most widely talked about topics in most OpenStack meets and summits, and has got a lot of attention from OpenStack community recently. With this release we see the support for NFV and some of the features starting with Nova. There is work being done around Neutron as well and will eventually see other OpenStack components getting support too. Sahara – The New Data Processing Service Big data has been a focus area for most companies and requires provisioning of humongous resources for performing analysis. This is where Sahara lets you quickly provision and manage big data clusters using Hadoop & Spark. During provisioning it also lets you specify parameters like Hadoop version, cluster topology, nodes details etc. It is also a part of the Horizon dashboard now, so all it takes is a few clicks. Glance Artifact Glance will eventually catalog not only Images (required for Nova) but also other objects/data assets required by different services. This will make Glance

Red Hat Enterprise Linux OpenStack Platform 5.0 – What’s New?

Posted on August 13, 2014 by Sangram Rath | Comments(0)

  On July 8 Red Hat announced the general availability of the third release of its OpenStack version, the Red Hat Enterprise Linux OpenStack Platform 5.0, which is an Enterprise grade platform for building public, private and hybrid clouds. It is based on the recent Icehouse release of OpenStack and built on the newer Red Hat Enterprise Linux 7 and Red Hat Enterprise Virtualization 3.4 which were released recently. This release includes many new features that will provide better availability, security, agility & performance. Let’s see some of these feature highlights. RHELOSP 5.0 now comes with a 3 year support lifecycle which is a sweet sound for enterprise Customers. This is a great news specially for production deployments as longer support means they can have increased focus on the business rather than the infrastructure. Further Red Hat also assures an easier upgrade path for upcoming OpenStack releases. Customers can now use their existing VMware infrastructure as OpenStack compute nodes due to improved and better integration of RHELOSP 5.0 with VMware. It also supports the VMware NSX plugin for OpenStack networking and VMDK plugin for Cinder block storage. Further, all this can now be easily managed from Horizon. RHELOSP 5.0 now offers data

OpenStack turns 4

Posted on July 22, 2014 by Sangram Rath | Comments(0)

  OpenStack turned Four this month. Happy 4th Birthday OpenStack !! From an initiative back in 2010 by NASA & Rackspace to a worldwide community of 17670 members and 70 user groups across 140 countries and 391 Organizations involved is a laudable achievement in 4 years. Termed as the year of the SuperUser, on this birthday industry leaders talked about their work around OpenStack in their organizations and share the knowledge they have gained during this process. Visit for videos, presentations and user stories. Factors like re-usability of existing server infrastructure, being able to use Commodity Hardware, comparatively lower cost of setup as compared to other private cloud options, improved performance, latency (since its private) and agility makes OpenStack all the more attractive for businesses / enterprises to adopt and it is only set to grow in the coming years with so many improvisations & new features being incorporated into it. Some of the notable ones to keep an eye are: Sahara for provisioning Hadoop clusters on OpenStack for data processing Puppet module for OpenStack Improvements to Trove (database as a service) Ironic for OpenStack bare metal provisioning (available as an incubated project in Icehouse) OpenStack is already being used by many companies

Red Hat CloudForms – A Cloud Management Platform for OpenStack & More

Posted on May 29, 2014 by Sangram Rath | Comments(0)

  OpenStack is great but it is not an Operating System in itself. It is a group of components with a modular architecture that uses an underlying Operating System like Red Hat Enterprise Linux to provide cloud capabilities. And although it has components that provide great cloud features, it needs a management platform to provide capabilities like self-service, service catalog, chargeback, workload life-cycle process, integration with public clouds & a change management process to name some of them. Further most companies today or in the near future will be using a heterogeneous Cloud environment, where the workloads will be distributed across different virtualization & cloud vendors (Private or Hybrid) like AWS, OpenStack, VMware etc. So you need a management platform that can manage all of them together.   Red Hat’s CloudForms provides this (I won’t say complete but its evolving good & fast) management platform to manage cloud resources across private & hybrid deployments. It also let’s you transform your virtual infrastructure (e.g. VMware) into a private cloud and with release 3.0 it now supports Red Hat Enterprise Linux OpenStack Platform as well. For those of you using Amazon Web Services (AWS) EC2, CloudForms also let’s you integrate it as an extension

Multi-Node OpenStack Icehouse installation on AWS using RDO

Posted on May 20, 2014 by Sangram Rath | Comments(11)

  In my previous blog, I wrote about my experience installing a single-node OpenStack Icehouse on a desktop/laptop using RDO. In this blog I will be demonstrating how to set up a simple Multi-Node OpenStack installation on AWS (Amazon Web Services). This is ideal in situations where we do not have access to hardware for setting up a multi-node installation or simply don’t have the time to setup machines for the same. Since I intend to just demonstrate the possibility of running OpenStack on AWS, I will keep the architecture simple. I would also like to state that such setups should be used purely for trying out OpenStack and not for production. My architecture will contain 1 Controller Node & 2 Compute Nodes. I will also try to keep the costs as low as possible. So I will use the smallest EC2 instance that will do the job. Unfortunately we cannot use t1.micro instances which are eligible for free tier since the memory in them is very low. (I did try though and it failed with “not enough memory” error message). AWS Services: Compute (EC2) - 3 X General Purpose m1.small instances, EBS backed Networking - Default Private and Public IP assignment by AWS. In case you wish to assign IPs

Try OpenStack Icehouse with RDO

Posted on May 12, 2014 by Sangram Rath | Comments(2)

  OpenStack’s 9th release Icehouse is here and I decided to give it a spin. I will be performing the installation on RHEL 6.5 and what better way to try out OpenStack than Red Hat’s RDO. For starters RDO is a community version of Red Hat Enterprise Linux OpenStack Platform. Read more about RDO here. I encountered a lot of errors during the installation and it was not as straight forward as mentioned in the RDO quick start guide. So the steps outlined here along with the changes is a result of my experience with the installation process. I performed some additional pre-requisites and ran some additional commands to ensure a smooth installation. The changes are highlighted in bold. Pre-requisites: A desktop/laptop with decent CPU, RAM & HDD. Most newer machines with Core i3 & above with 4GB RAM would suffice. A hypervisor like VMware Workstation, VMware Player or Virtualbox A Linux Virtual Machine or a Linux distro to create one. For Icehouse Red Hat 6.5 is recommended. Distros like Fedora (20 or above), or similar ones based on Red Hat or Fedora like Cent OS (6.5 recommended), Scientific Linux will also do. I will be installing it on Red Hat EL

OpenStack ICEHOUSE is here to chill you this summer

Posted on April 29, 2014 by Sangram Rath | Comments(0)

  April 17th marked the availability of the 9th release of OpenStack. Code named “ICEHOUSE” it comes at a right time in Summer to chill you with a staggering 350 new features. Keep aside the gimmick and that’s what I call a “Community Effort”. Let’s have a look at some of the new features and enhancements in OpenStack Icehouse. I will be covering only some of the new features for each component that I feel matters to an everyday OpenStack administrator. Trove One of the new additions to OpenStack that I was really looking forward to was the launch of the Database Service. Code named “Trove”, it provides database as a service through the OpenStack environment. The goal is to quickly provision database instances without having to manage the administrative tasks like deployment, patching, backups, configuration etc. – Currently it has full feature support for MySQL and Precona and experimental for some other ones. But it won’t be long before others are fully supported. – You have the ability to resize the flavor instance and the cinder volume. – There is support for backup and restore as well. Nova – Now includes support for rolling upgrades, which means live upgrades are
