Liberty Is First OpenStack Release Under ‘Big Tent’ Model

 

The Liberty release, the second major OpenStack update this year, includes a wealth of new projects and features, while core technologies continue to evolve.

The OpenStack Liberty release, set to become generally available on Oct. 15, will provide users of the open-source cloud platform with new projects and features. The second major OpenStack update in 2015, the Liberty release follows Kilo, which debuted on April 30.OpenStack Liberty is noteworthy for many reasons, not the least of which is the fact that it is the first release under the “Big Tent” model, which takes a more inclusive approach for projects. As such, with OpenStack Liberty, there are more new projects as part of the coordinated release than ever before, including SearchLight search, Zaqar messaging, Barbican key manager, Manila shared file system and Designate DNS services among others.”OpenStack is a platform for integrating a wide variety of technologies,” Jonathan Bryce, executive director of the OpenStack Foundation, told eWEEK. “With the Big Tent shift, it has allowed people within the OpenStack community to select different focus areas, so we’re seeing a lot of innovation.”The SearchLight search project in OpenStack Liberty is a new effort that has come up in the last year, Bryce said. SearchLight uses the open-source ElasticSearch technology to enable users to query across an OpenStack deployment. Bryce noted that OpenStack has been using ElasticSearch as part of its development process for several years to search though development logs and test results. He added that members of the OpenStack community thought about how to evolve the limited use of ElasticSearch within OpenStack development into a full OpenStack cloud service, which is now what SearchLight represents.

As an integration platform, OpenStack as a platform always seeks to enable multiple technology options within any given service, and SearchLight is likely not going to be an exception. Currently, SearchLight relies on ElasticSearch, but there is a plug-in system that is part of the overall architecture, Bryce said.

“So while ElasticSearch is currently the default and the reference implementation, the design of SearchLight is built to enable other search systems and back-ends,” Bryce said.In contrast to SearchLight, which is new to the OpenStack community, development on the Zaqar messaging service has been ongoing for several years. The Zaqar project was originally known as Marconi, and was renamed in 2014. Zaqar is a multi-tenant cloud messaging service, somewhat akin to what Amazon’s Simple Queue Service (SQS) delivers.”Zaqar is a project that is meant to be a plug-in-driven system,” Bryce explained. “Really, it’s about providing multi-tenant messaging via a REST API.”Nova ComputeWhile the Big Tent model provides a platform for many different projects to be included with OpenStack, the core projects are also getting attention in the Liberty release. The Nova compute project adds multiple features to OpenStack’s core server virtualization effort. For Bryce, the biggest new feature is Cells version 2. Cells first landed in the OpenStack Grizzly release back in April 2013 as a technology to enable multiple Nova Compute modules to be managed by a single Nova API.”Cells came out of Rackspace as a technology to help scale across data centers and geographic regions,” Bryce said. “The first version took a long time to get upstream as it was very specific to the Rackspace environment.”With Cells version 2, the model is significantly more generic, enabling broader use and deployment options.

The Basic Knowledge of PHP Website Development That You Should Have Before Starting a Website

In today's world website development is at a high tide. All the companies are using websites to display their details and plans.

It can allow the web developer to create dynamic web-pages that can start from a very simple page to pages involving complex mechanisms. An important advantage of PHP is that it can be directly integrated with the HTML code and will run easily. The HTML can be run using PHP by using the.php extension. Another important feature of this language is that it allows us to include dynamic and robust features in the website and can increase the attractiveness of the site. Most of the clients are interested in giving the work of the website to a professional PHP website Development company.

For uploading and the smooth working of a PHP website it is necessary to have a web hosting company. But before allocating and assigning your work to any web hosting services it is necessary to not a very few features. One of the most important features that a web hosting service should provide is suitable database support. Most of them give a single database for your website. But if you are planning a large site this may not be enough. Another thing is the file system. The web hosting service should allow files to be uploaded. This is necessary in the utmost when you are in the process of building your site and you still have files to upload. Another thing is to find if the web hosting service is providing the correct version of PHP. There are many web hosting services that do not support PHP at all. So take a notice of that too. All the important details regarding a web hosting service will be listed in their website. So make it a point to visit their website before making any final commitment.

Ubuntu Cloud Images Come To The Google Cloud

The widely-used Ubuntu operating system is about to become a little more popular. As of today, Canonical and Google will support Ubuntu Cloud images on the Google Cloud Platform. According to Canonical, 70 percent of all cloud workloads run on Ubuntu architecture.
Ubuntu Cloud images are now in beta for Google’s service. In particular, Canonical has brought support for Ubuntu 14.04 LTS and 14.10, as well as 12.04 LTS. All Ubuntu releases have guaranteed support for five years.
The latest LTS release, 14.04, provides support for numerous software and hardware architectures. The release added ARM multiplatform, ARM64, and IBM POWER support. Additionally, KVM 2.0.0 is now supported alongside Xen and VMware solutions.
“Bringing Ubuntu to Google Cloud Platform is a logical first step in what we believe will be a great collaboration, benefiting developers and enterprises looking for an easy-to-use, reliable OS for their cloud deployments,” said Certified Public Cloud product manager Federico Lucifredi.
This beta means Ubuntu is now on the three biggest public cloud platforms: AWS, Azure, and now Google Cloud Platform. Canonical isn’t done yet though – the company also announced the release of an Ubuntu OpenStack distribution.
Canonical founder Mark Shuttleworth calls the distribution an “autopilot” for OpenStack. “Point it at a rack or ten and tell it your preferences for storage, software defined network, and hypervisor, and it will create your cloud automatically, manage and monitor it for you, keep it fully secure, and update it to the next version of OpenStack in due course.”

In order to add machines to the OpenStack deployment, IT admins simply boot and allocate the machine using Canonical's Landscape tool. The machine is then added to the metal as a service (MAAS) and can be monitored using the same Landscape interface.
Canonical's OpenStack distribution is now in beta. For more information on the latest Ubuntu releases head to the Ubuntu Cloud product page.

Red Hat Certified Architect

Red Hat Certified Architect (RHCA) is the Master Level Certification Program with in-depth, hands-on training for Senior Linux System Administrators enabling them to design and deploy large and complex Linux based environments. This is a capstone Certification, and shall be above RHCSA, RHCE, RHCVA, RHCDS, RHCSS etc.

It is only required that pass any FIVE of the listed modules to earn this title.

RH 413 - Red Hat Server Hardening  RH 401  - Red Hat Enterprise Deployment and Systems Management RH 436  - RedHat Enterprise Storage Management RH 442  - Red Hat Enterprise System Monitoring and Performance Tuning RH 318 - Red Hat Enterprise Virtualization CL210 -  Red Hat OpenStack Administration RH236 -  Red Hat Storage Administration JB248 -  Red Hat JBoss Application Administration CL280 -  - Red Hat OpenShift Enterprise Administration CL220 -  - Red Hat CloudForms Hybrid Cloud Management

Unlike the RHCSA and RHCE certification programs, RHCA courses can be pursued on module basis i.e. each course can be taken separately and Redhat endorsement can be achieved for that particular course by taking the certification exam successfully for the same, making it convenient for senior administrators to choose their area of specialisation without going through the entire course saving money and time. This compartmental system also provides the flexibility to attain RHCA in a
