New Linux Contextualization Packages

We have released new Linux contextualization packages (ver. 5.4.2) with wider platform support, a few improvements and bugfixes. This release is a major update. New packages are available for download on the GitHub with updated documentation for KVM/vCenter environments. Packages are compatible with the OpenNebula versions from 4.6 to 5.4.

The main focus of this release was to come again with updated packages for the Amazon EC2 environments used via OpenNebula Cloud Bursting; these packages weren’t updated for some time. Currently, only main systemd platforms CentOS 7, Ubuntu 16.04 and Debian 9 are supported via the dedicated one-context-ec2 packages, but other similar systems should work as well. Also, we have aligned the support for Alpine Linux contextualization (formerly maintained in the separate repository) and merged the required changes into the general Linux contextualization repository. From this release on, we provide the Alpine Linux package for easy setup. A fix contributed by Dmitry Tyzhnenko ensures the sudo configuration is created, if the contextualized user (specified via context parameter USERNAME) is different to root. There are also several bugfixes in the scripts, dependencies, and package creation. Please see the complete release notes on the download page.

On top of that, new KVM appliances with Alpine Linux 3.6 and Fedora 27 were added, and most of our existing generic Linux KVM appliances were updated on the OpenNebula Marketplace.

We have added the very new EC2 contextualized appliances on the OpenNebula Marketplace for a quick start with the OpenNebula Cloud Bursting on the Amazon EC2! These are available for the current generation of the EBS based HVM instances in the EC2 region us-east-1.

In case of any questions, you can use our public forum or submit an issue on the GitHub.

Berta – Managing The Lifecycle of Virtual Machines

Managing resource usage in private or community clouds where the provisioning model is not pay-per-use oriented is often complicated. Resources are available to end users seemingly for free which means that one of the main motivators for responsible resource usage — a monthly bill — is missing. This can eventually lead to a situation in which the pool of available resources is depleted and a large portion of existing allocations is underused, unused, or entirely forgotten. For a resource provider interested in offering fixed amount of resources to the largest possible number of users, this issue needs to be addressed. Read more

15:30 – 16:00: Disaster Recovery solution with OpenNebula and StorPool

Boyan Krosnov,Chief of Product of StorPool

In this talk we’ll explore a DR solution based on OpenNebula, developed by StorPool and deployed at a financial services organization. This solution represents a break-through for OpenNebula and StorPool technologies in a very conservative sector.
The solution uses two OpenNebula orchestrators using the federated identities scheme and two StorPool storage systems connected to each other with an encrypted site-to-site link.
It highlights how easy it is to extend OpenNebula to perform additional functionality, even without modifying the upstream OpenNebula software.

16:30 – 17:00: Demo OpenNebula and VMware vCenter

Javi Fontán, OpenNebula Developer

In this demo OpenNebula will be shown managing a vCenter infrastructure.

Make sure you register soon as the seats are almost gone! There will be a live stream of the event so stay tuned for more information.

Hybrid Clouds: Dancing with Virtual Machines

Today, the model of hybrid cloud comes under the eyes of a lot of organizations. The idea of combining resources of public cloud providers with private depending on the terms of execution, the need of more resources, an extra protection of the data, more or less security in services with sensitive information, etc. are some of the capabilities that this model has to answer. The case of CSUC, acting as Opennebula powered cloud provider and at the same time as user of external IaaS and PaaS services, is analyzed sharing its first experiences in the way to archive a real multicloud architecture.

hybrid_cloud

Figure 1- The Hybrid Cloud, acts as a slicing bridge.

The majority of organizations have not been born in the “cloud”, situation that produces a lot of cases where the cloud resources have to interact or to be connected to traditional systems and applications with some criticality and usually are situated in its own dependencies. This kind of architecture is the most usual, where the main keys for its success go through to be aware about things like the integration capabilities or the impact in the organization roles where could exist different interpretation of the same concept.

For a solutions designer the model has to offer flexibility, speed and capacity. In the case of the infrastructure team it’s easy to think that more “different things” have to be managed. The business development staff will ask if it will be more expensive and which is the value that the hybrid model will contribute.

From the IT infrastructure perspective, when a public cloud provider is selected/procured, a good approach to start with in the adoption of hybrid cloud model is to focus in these first three challenges.

  • Networking: to extend your network layers with capable “dedicated” circuits provision with bandwidth control outside and inside public cloud provider(s).
  • Management: to consolidate a truly global infrastructure management platform through a cloud orchestrator and its cloud bursting capabilities.
  • Security: to extend to public cloud provider current security layers (platforms, tools, policies,…) under the current organizations umbrella.

Definitely, the model or architecture to implement will be different depending on each case where the applications/services have a lot to say and have to be listened. The pure reality is that nowadays almost all the organizations work in two different speeds and this is something that the technology departments have to work with. Some very changing environments like web and mobile applications and other more robust systems associated to critical processes with high levels of stability and security. A real cloud hybrid model should support the combination of this two speed ecosystems maintaining its specific dependences and needs.

The CSUC use case: driving to a hybrid cloud architecture

CSUC, in these last two years has worked in these challenges with some actions that are transforming roles, the management models at ICT infrastructure level, the way of services provision, etc.

The first action was to start a procurement process to provision the first IaaS provider with the idea of infrastructure and services optimization in a new model of payment by use. In parallel as RREN, the adoption of a orchestrator role with its own cloud management platform (Opennebula based) to manage distributed resources in a real multicloud environment. The network design, the unified management and security conditioned the strategy.

Regarding the new external cloud provider and after an a intense procurement process, the company Nexica  resulted adjudicator for four years of the provision of IaaS services for Catalan Universities and CSUC.

Nowadays, the catalan institutions who are using this shared service are:

What work has already been done:

  • First IaaS provider procurement process.
  • Service catalog, service-level agreements and governance.
    Architecture redefinition.
  • RREN extended to the provider: Layers 2&3.
  • A new Opennebula cloud bursting driver was developed (VCLOUD compliance)
  • Integration of CSUC opencloud orchestrator.
  • Deployment of first production services.
