Claudia, an open-source service manager integrated with OpenNebula

As part of its exploitation strategy, Telefónica I+D has decided to release as Open Source a number of components developed during its research on Infrastructure as a Service (IaaS) Clouds.  These components will be integrated in the Claudia Platform that will offer a Service Management toolkit to deploy and control the scalability of service among a public or private IaaS Cloud. Telefónica I+D chooses MORFEO Project to release the software because it guarantees the access to the results of research beyond the end of the project.

These components will continue evolving and put into a “production” status by Telefónica I+D. Each component will be released with its own Open Source License (GPL, Apache, MPL, etc.). Telefónica I+D will also provide commercial support following a dual-license schema.

The Claudia Platform is aligned with the Morfeo’s Cloud Technologies Chapter vision of integrating a complete Open Source Stack for managing a IaaS Cloud. In this way, Claudia will be fully integrated with OpenNebula through the OCCI API as both are members of the chapter.

A Flexible and Interoperable Cloud Operating System

Slide1Future enterprise data centers will look like private clouds supporting a flexible and agile execution of virtualized services, and combining local with public cloud-based infrastructure to enable highly scalable hosting environments. The key component in these cloud architectures will the cloud management system, also called cloud operating system (OS), being responsible for the secure, efficient and scalable management of the cloud resources. With high-end computing demands, cloud operating systems will continue to be a very active field of research and development; in many ways displacing “traditional” OS to be part of the application stack.
Functionality of Open Cloud Operating Systems
A Cloud OS deal with the complexity of a distributed infrastructure in the execution of virtualized service workloads. The Cloud OS manages a number of servers and hardware devices and their infrastructure services which make up a distributed system, giving the user the impression that they are interacting with a single infinite capacity and elastic cloud. In the same way that multi-threaded OS define the thread as the unit of execution and the multi-threaded application as the management entity, supporting several communication and synchronization instruments; multi-tier Cloud OS define the VM as the basic execution unit and the virtualized services (group of VMs to execute a multi-tier service) as the basic management entity supporting different communication instruments and their auto-configuration at boot time. This concept helps to create scalable applications because you can add VMs as and when needed. Individual multi-tier applications are all isolated from each other, but individual VMs in the same applications are not as they all may share a communication network and services as and when needed.
A Cloud OS has a number of functions:
– Management of the Network, Computing and Storage Capacity: Orchestration of storage, network and virtualization technologies to enable the dynamic placement of the multi-tier services on distributed infrastructures, combining both data center resources and remote cloud resources.
– Management of VM Life-cycle: Smooth execution of VMs by allocating the resources required for them to operate and by offering the functionality required to implement VM placement policies, such as migration
– Management of Workload Placement: Support for the definition of workload and resource-aware allocation policies such as consolidation for energy efficiency, load  balancing, affinity-aware, capacity reservation…
– Management of VM Images: Exposing of general mechanisms to transfer and clone VM images
– Management of Information and Accounting. Provision of indicators that can be used to diagnose the correct operation of the servers and VMs and to support the implementation of the dynamic VM placement policies
– Management of Security: Definition of security policy on the users of the system, guaranteeing that the resources are used only by users with the relevant authorizations and isolation between workloads
– Management of Remote Cloud Capacity: Dynamic extension of local capacity with resources from remote providers
OpenNebula is an open cloud OS that provides above functionality on a wide range of technologies. However, in my view, the main differentiation of OpenNebula is not its leading edge functionality but its open, modular and extensible architecture that enables its seamless integration with any service and component in the ecosystem.
Interoperability at Cloud Management Level
Being the core component in any Cloud solution, interoperability is crucial for the success of a cloud management system. We can compare the Cloud OS with a the kernel in “traditional” operating systems. The Cloud OS represents the basic functions in a cloud and requires a well defined communication with underlying devices and interface to expose administration and user functionality.
At the cloud management level, interoperability means:
– Modularity and flexibility to easily interface with any service or technology in the virtualization and cloud ecosystem, and
– Standardization to avoid vendor-lockin and to create a healthy community around
In fact interoperability should be evaluated from three different angles:
– Infrastructure User Perspective: Users, application developers, integrators and aggregators are requiring a standard interface for the management of virtual machines, network and storage. OCCI is a simple REST API for Infrastructure as a Service based Clouds that is being defined in the context of OGF. This interfaces represents the first standard specification for life-cycle management of virtualized resources. OpenNebula has been the first referent implementation of this open cloud interface, and also implement the Amazon EC2 API.
– Infrastructure Management Perspective: Administrators are requiring cloud OS to be integrated into existing infrastructure and management services, so fitting into any data center. OpenNebula provides a flexible back-end that can be integrated with any service for virtualization, storage and networking.
– Infrastructure Federation Perspective: Administrators are requiring cloud OS to grow using resources from partner and commercial clouds
The open and flexible approach for cloud management ensures uptake and simplifies adaptation to different environments, being key for interoperability. The existence of an open and standard-based cloud management system like OpenNebula provides the foundation for building a complete cloud ecosystem. This ensures the new components and services in the ecosystem have the widest possible market and user acceptability.
OpenNebula is being enhanced in the context of the RESERVOIR project, flagship of European research initiatives in virtualized infrastructures and cloud computing.

Future enterprise data centers will look like private clouds supporting a flexible and agile execution of virtualized services, and combining local with public cloud-based infrastructure to enable highly scalable hosting environments.

Moreover, as pointed out in the CloudScaling “Infrastructure-as-a-Service Builder’s Guide“, the right configuration and components in a Cloud architecture also depend on the execution requirements of the service workload.

Interoperability at the Cloud Management Level

The IEEE defines interoperability as “the ability of two or more systems or components to exchange information and to use the information that has been exchanged” and Wikipedia introduces  interoperability as “the property referring to the ability of diverse systems and organizations to work together (inter-operate)“. Being the core component in any cloud solution, interoperability is crucial for the success of a cloud management system.

Haizea 1.0 now available

The first stable version of the Haizea Lease Manager was released a few days ago and is available for download at http://haizea.cs.uchicago.edu/

Haizea can be used as a drop-in replacement for OpenNebula’s scheduling daemon, providing OpenNebula with more advanced scheduling capabilities such as advance reservations and queueing of requests when there are no resources available.

Haizea 1.0 is compatible with the recently released OpenNebula 1.4 and, compared to the last major release of Haizea (Technology Preview 1.3 in February 2009), introduces many new features focused on:

  • Extensibility: A new modular scheduler design that makes it easier to choose between different scheduling policies, or to write custom policies that can be “plugged into” Haizea. Writing a custom policy only requires writing a Python module implementing a set of methods described in the Haizea documentation.
  • Stability: Many internal changes, including a larger number of unit tests, that make Haizea more stable.
  • Documentation: More documentation, including developer documentation for users interested in extending Haizea or writing custom scheduling algorithms or policies.

For a list of all the new features, take a look at the Haizea Changelog

Work on Haizea 1.2 is already under way, and will include the following features:

  • Support for leases with deadlines. Haizea will include deadline-driven scheduling algorithms such that, if a user specifies a deadline for a lease, Haizea will only accept if it can be scheduled before that deadline. Furthermore, preemptions (if allowed by the lease) will only be done if the deadline restriction is still met.
  • Lease negotiation. The lease lifecycle will be expanded to incorporate a negotiation phase before a lease is accepted. In this negotiation, it will be possible for Haizea to reply to a lease request with multiple possible leases which the user can accept or reject. The initial focus in this work will be on supporting lease pricing.
  • Lease pricing. Haizea will be able to price leases, based on pluggable pricing leases.

Since most of the work for 1.2 is driven by research efforts, the focus for the next couple of months is going to be mostly on the simulation side of Haizea. Nonetheless, improving the integration between Haizea and OpenNebula, particularly in regards to making Haizea more aware of unscheduled changes in the VMs (an issue that several users have brought to our attention), is still part of our long-term goals. However, we don’t anticipate we”ll be able to work on improving that part of Haizea until, at least, the summer. Nonetheless, if there are developers who would be interested in helping to improve the Haizea/OpenNebula integration (specially those who have a stake in this integration), please don’t hesitate to let us know, as we’d be happy to provide assistance.

OpenNebula Cloud Announcement

The OpenNebula Team is proud to announce the dawn of the OpenNebula Cloud. Although this can be shortened to ONE Cloud, it is in fact two, although both of them are accesible using two interfaces: OCCI and EC2.

  • Dummy cloud. This cloud offers an interface to an OpenNebula instance configured using dummy drivers. This means that it will offer a seemingly infinite capacity to run VMs, but it actually won’t ever run any VM instance. This ‘dummy’ cloud is offered to test the OCCI and EC2 inte rfaces
  • Real cloud. The OpenNebula instance that supports this clouds has access to physical server, and will offer the possibility of configure virtual networks, launching real VMs and access them using public IPs. This ‘real’ cloud VMs will have a limited capacity and is not meant to provide VMs on demand for personal uses, but rather to test OpenNebula cloud functionality.

The aim of these clouds is to allow for interface testing and foster the creation of an ecosystem built on top of OpenNebula clouds.

More information on configuration of the clients and usage of the two clouds can be found here.
