XtreemFS 1.5 released: Improved support for Hadoop and SSDs

The XtreemFS team released a new stable version of the cloud file system XtreemFS. XtreemFS 1.5 (Codename "Wonderful Waffles") comes with the following major changes:

- Improved Hadoop Support: Read and write buffers were added to improve the performance for small requests. The team also implemented support for multiple volumes e.g., to store input and output on volumes with different replication policies.
- SSDs support: So far, an OSD was optimized for rotating disks by using a single thread for disk accesses. Solid State Disks (SSDs) cope well with simultaneous requests and show a higher throughput with increased parallelism. To achieve more parallelism per OSD when using SSDs, multiple storage threads are supported now.
- Multi-Homing Support: XtreemFS can be made available for multiple networks and clients will pick the correct address automatically.
- Multiple OSDs per Machine: Machines with multiple disks have to run an OSD for each disk. The team simplified this process with the new xtreemfs-osd-farm init.d script.
- Bugfixes for Read/Write and Read-Only Replication: The team fixed a problem which prevented read/write replicated files to fail-over correctly. Another problem was that the on-demand read-only replication could hang and access was stalled.
- Replication Status Page: The DIR status page has got a visualization for the current replica status of open files. For example it shows which replica is the current primary or if a replica is unavailable.

The team prepared a tutorial which walks you through the setup of a read/write replicated XtreemFS volume on a single machine. The tutorial lets you stream a video from the volume and simulate the outage of a replica. You'll learn about the details of the XtreemFS replication protocol and why the video stalls for some seconds and then playback resumes.

AlmereGrid has put the tutorial to the next level: They created a setup of eight Raspberry Pi mini-computers running XtreemFS - packaged in a briefcase. Check the website CloudCase.eu for more details and the video which shows the briefcase and the demonstrated fail-over.

You can use XtreemFS directly in your application with our C++ and Java client libraries. This way you avoid any overhead due to Fuse and can access advanced XtreemFS features which are only available through the maintenance tool "xtfsutil" otherwise e.g., adding replicas.

From using XtreemFS it's only a small step to dive into the XtreemFS source code itself. The team collected several introductory documents for novices in a Google Drive folder "XtreemFS Public". For example, have a look how to setup the XtreemFS Server Java projects in Eclipse.

ConPaaS releases a preview of version 1.4.0

The ConPaaS team has launched a new release: ConPaaS-1.4.0. This release is different from previous ones in that it is a preliminary version meant as a technology preview. This version has not been fully tested so it is not suitable for production usage. For production usage the team suggests using ConPaaS-1.3.1.

New features in ConPaaS-1.4.0 includes the following:

  • The XtreemFS service now enforces strict access control using ssl certificates. Two types of certificates are now supported:

a) user certificates: contain a username and group (recommended)
b) client certificates: the local username and group are forwarded to XtreemFS (for trusted environments)

  • A new MySQL Galera service is introduced. This service is meant to replace the old MySQL service with a better implementation of database replication based on Galera cluster.
  • Users can now log in to ConPaaS using an external identity provider such as theContrail IdP.
  • ConPaaS now has a new set of command-line tools called cps-tools which exhibits a more regular syntax than the old cpsclient.

ConPaaS is a runtime environment for hosting applications in the Cloud. It aims at offering the full power of the Cloud to application developers while shielding them from the associated complexity of the Cloud. ConPaaS is designed to host both high-performance scientific applications and on-line Web applications. It automates the entire life-cycle of an application, including collaborative development, deployment, performance monitoring, and automatic scaling. Finally, it runs on a variety of public and private Clouds, and is easily extensible. This allows developers to focus their attention on application-specific concerns rather than on Cloud-specific details.

For more information about the ConPaaS project as a whole the team recommends the overview article.

To try the new release the simplest option is ConPaaS Online: new users can register and try the system for free during a limited period.

Contrail project team to organize Contest Competition at Euro-Par 2013

The Contrail project team is organizing a Contrail Contest Competition in the framework of the Workshop on Dependability and Interoperability in Heterogeneous Clouds (DIHC13), collocated with Euro-Par 2013, on August 27, 2013 in Aachen, Germany. The deadline for registration and code submission is August 10, 2013. The winner will be notified on August 15, 2013.

Contrail brings a number of important features to Cloud administrators and users. With the Contrail software a Cloud administrator now can manage a Federation of Clouds providing support for basic SLA functionalities at the provider level on top of the deployment and management of the entire life-cycle of applications on a data centre. A user accesses the Federation Web, which is completely integrated with authentication and authorization functionalities, meaning that user login obtains proper OAuth tokens that can be used for other calls.

Applications are described via proper OVFs, where virtual networks can also be specified. A Contrail user can also access PaaS services via the ConPaaS component, designed to host both high-performance scientific applications and on-line Web applications. Contrail is available either as integrated software or as a set of individual components: ConPaaS (PaaS services), Security (authentication and authorization), SLA life-cycle management, VEP (data centre and application management), VIN (virtual networks), GAFS (reliable distributed storage).

Contrail is a European project addressing interoperability and dependability to allow a federation of heterogeneous Clouds to deploy distributed applications under QoS and QoP constraints. Contrail is an open source integrated approach to virtualization, offering Infrastructure as a Service services (IaaS), services for federating IaaS Clouds and Contrail Platform as a Service services (ConPaaS) on top of federated Clouds. The aim of the project is designing, implementing, evaluating and promoting an open source computational Cloud wherein users can limitlessly share resources. The Contrail is at the third public release of the software stack and is thus targeted to the researchers and technology enthusiasts.

The contest competition shall provide a forum to present and discuss the use of Contrail software: new applications using the Contrail software stack or some of its components, demonstration testbed of an existing application ported on Contrail, new tools that interoperate with and integrate Contrail software.

Submissions should be in the form of a package including the code accompanied by a two-pages proposal providing informal description of the demonstration (consisting of an application or tool), which parts of the Contrail software have been used, the experience in installing and using the Contrail software and advantages (if any) of using the Contrail software, what attendees will be able to see or do during the demo (e.g. screenshots). The same document must provide information about any equipment or facilities required for your system demonstration.

All submissions will be evaluated mainly based on the quality of work, novelty of the application or tool, the potential to stimulate interesting discussions, exchange of ideas and promote collaborations.

The winner of the competition will present at the DIHC 2013 workshop to present the application/tool and work accomplished. The winner will also be invited to submit a paper to be published in the post-proceedings of the workshop. More information will come after the workshop.

The DIHC 2013 workshop aims at bringing together researchers from academia and industry interested in the design, implementation, and evaluation of services and mechanisms for dependable Cloud computing in a multi-­Cloud environment.

Detailed information is available at the Contest website.

Report on Cloud Computing SLAs in FP7 now published

The rapid evolution of the cloud market is leading to the emergence of new services, new ways for service provisioning and new interaction and collaboration models both amongst cloud providers and service ecosystems exploiting cloud resources. Service Level Agreements (SLAs) govern the aforementioned relationships by defining the terms of engagement for the participating entities. The European Commission has issued a report following the Workshop on "Cloud Computing SLAs in FP7 - Exploitation of Research Results", organised by the unit CONNECT E2 "Software & Services, Cloud" of the European Commission in Brussels on 27 May 2013. The download is now available.

VEP 2.0 is now available

Virtual Execution Platform is a Cloud middleware software that interfaces multiple Infrastructure as a Service (IaaS) Clouds. VEP offers two types of services:

  1. management of data centres for a Cloud administrator allowing greater control on the physical resources;
  2. management of end-user distributed applications made up of several inter-networked virtual machines on a Cloud with an interface facilitating the deployment and application lifecycle management.

The VEP team is proud to announce VEP v2.0 (download link here), a new version replacing the old one (v1.1). The supported features are:

  • OpenNebula: VEP allows to manage a OpenNebula Cloud System offering a completely transparent interface
  • Open Standard support: VEP respects the DTMF OVF and CIMI standards
  • Data centre representation: VEP stores the provider data centre layout to enforce some SLA requirements
  • Physical resource allocation and resource provisioning for end user’s applications
  • Easy interfaces: easy browser based Cloud administrator and end-user application management interfaces
  • Application snapshot: creation of OVF file to redeploy the application at a later time or in another data centre
  • VM Scheduling: the new VEP scheduler is independent from the IaaS Scheduler to allow placement constraints on the resources
  • Advance Reservation: VEP allows to reserve a number of VMs from a start date to an end date to guarantee the deployment (in addition to run an application in best effort mode).

VEP aims at offering the full management of IaaS Cloud while shielding the administrators from the complexity of managing heterogeneous resources. VEP is designed to provide interoperability by offering a uniform way of representing and managing the resources of a Cloud provider. VEP could also easily enable the participation of a Cloud provider to a federation seamlessly and it does proper VM contextualization and application lifecycle management. Additionally it publishes application events and metrics for application’s monitoring and SLA enforcement.
VEP enables interoperability through its RESTful interface based on the DMTF’s Cloud Infrastructure Management Interface (CIMI) standard. The CIMI model defines a framework for the application life cycle management on a Cloud provider infrastructure, with applications generated from an Open Virtualization Format (OVF) document. VEP extends the CIMI API to support the deployment of applications under SLA terms.

VEP RESTful interface allows Cloud administrators to manage and control numerous aspect of the service offering. For VM scheduling to work properly, the data centre topology information is desired in VEP. The software has a simple and intuitive interface to allow administrators input topology information about their data centre. This interface also permits the administrator to selectively permit hosts to be managed via the VEP software. VEP never schedules a VM on a host not permitted for use by the administrator.

An Installation Guide and a User Guide is availabe at the VEP project site (https://project.inria.fr/vep/documentation/).

The VEP team is working hard to make VEP an even better system; the Openstack support is around the corner.
Stay tuned for the the next releases.

XtreemFS 1.4 released at Supercomputing 2012

XtreemFS 1.4, a new stable release of the Cloud file system XtreemFS, has been released. This release is the result of almost one thousand changes ("commits") to the code repository, and extensive testing throughout the year.

The team worked both on major improvements to the existing code and new features:

  • Improved stability: Clients and servers are rock solid now. In particular, client crashes due to network timeouts and issues with the Read/Write file replication have been fixed.
  • Asynchronous writes: Once enabled (mount option "--enable-async-writes"), write() requests will be executed in the background. This improves the write throughput without weakening semantics. The team recommends to enable async writes.
  • Windows Client (beta): Complete rewrite based on the stable C++ libxtreemfs and using the Dokan alternative Callback File System by EldoS corporation. You can try it by mounting the public demo server.
  • Hadoop support: Use XtreemFS as replacement for HDFS in your Hadoop set-up. This version of XtreemFS comes with a rewritten Hadoop client based libxtreemfs for Java which also provides data locality information to Hadoop.
  • libxtreemfs for Java: Access XtreemFS directly from your Java application. See the user guide for more information.
  • Vivaldi integration: The Vivaldi replica placement and selection policies enable clients to select close-by replicas based on actual network latencies. These latencies are estimated using virtual network co-ordinates which are also visualized in the DIR web-interface. You can check out the demonstration on the web-interface of the public demo server.
  • Extended OSD Selection: Now you can assign custom attributes to OSDs and limit the placement of files on OSDs based on those attributes.

This version also includes an updated version of the DIR/MRC replication and adds fail-over support for DIR replicas. As DIR/MRC replication is still in a very early stage this feature is intended as technology preview for more experimental users.

The team is currently at the Supercomputing 2012 exhibition where they present XtreemFS at the Contrail booth #2535 as part of the Contrail project. Since the event takes place in Salt Lake City, Utah, the team decided for "Salty Sticks" as release name for the 1.4 version.

As XtreemFS is an open source project, the team is always looking forward to external contributions and believes that this release serves as an ideal starting point for that. Here's an incomplete list of things you might be interested to contribute:

  • chef recipe or puppet configuration for automatic deployment
  • a fancy Qt GUI for the client
  • S3-compatible interface based on the client library libxtreemfs
  • direct integration with Qemu/KVM using the C++ libxtreemfs

At last, the team invites you to fill out the survey if you use/have used/plan XtreemFS.
