TUTORIAL T1 – Practical Cloud Deployment and Management with Openstack and Programmable Networking
Date and Period: Monday AM, May 5, 2014
Speakers: Masum Z. Hasan and Horst Dumcke
Room: Gamma 1

Openstack has emerged as a major Cloud Framework (note we use the term "framework" as generalization of Cloud OS, Cloud controller, Cloud Management System, relevant software/API framework) for deploying large scale public and private Clouds. Openstack allows deployment of both computer and storage Clouds with the addition of other value-added services, such as VM image, identity, load-balancing and network related services. Programmable networking or PN (aka SDN) is another area that is changing the landscape of networking in a major way. In a Cloud all the services are on-demand and programmatic. That is, compute and storage resources are requested on-demand and via programmatic interfaces (aka API) with the resources made available to the requester almost immediately or in a short time interval since the request. In general, the CRUD (Create, Read, update, delete) of resources are performed on-demand and programmatically.  Cloud requires that network resources are also CRUD on-demand and programmatically. Hence PN or SDN comes in handy in a Cloud environment. In this tutorial we will cover following:
-        General Cloud concepts
-        Programmable Cloud and networking concepts
-        Show how these concepts are realized in the Openstack framework and PN/SDN framework, such as Cisco OnePK and Open source OpenDaylight (withe more focus on Openstack)
-        User management and access control framework (Keystone)
-        (VM) image management framework (Glance)
-        Compute Cloud framework (Nova)
-        Elastic block storage framework (Cinder)
-        Network services framework (Neutron; this is Openstack version of PN to support PN/SDN of server access network) object storage Cloud framework (Swift).
-        Introduction on Cisco OnePK
-        Introduction on Open Daylight.
-        Deployment of an Openstack controlled Compute Cloud in a multi-node or cluster environment
-        This will include neutron controlled network for the Compute Cloud
-        Deployment of an Openstack (Swift) controlled Storage Cloud over a pool of distributed storage (distributed on general-purpose computer servers).
-        Orchestration of multiple services in Openstack Cloud
-        A use case of on-demand QoS for compute/storage Cloud using PN/SDN/OnePK
-        Openstack Cloud spanning multiple DCs and MAN/WAN (Seamless Cloud)
-        Above will be accompanied by demos on a real Cloud infrastructure and programming examples.

TUTORIAL T2 – Manageability, Embedded Automation, Network Programming and Autonomic Networking – Contradicting Concepts or Complementary Evolutions?   
Date and Period: Monday AM, May 5, 2014
Speakers: Michael Behringer, Patrick Charretour, Joe Clarke, Bruno Klauser, Jason Pfeifer
Room: Gamma 2

While software-defined approaches in many IT domains, including network programming, enjoy a lot of attention currently, evolutions of network-embedded automation are powering an increasing number of innovative operational scenarios. At the same time decades of research, development and investment into basic manageability and operational experience are being leveraged to define control loops which tackle routine tasks autonomously. 
Are these independent developments or even competitive concepts? Should ‘pure’ implementations rely on a single approach? Can they be combined to reap all the benefits in parallel? Or might they be an integral part of the bigger picture as networking evolves? Why are software-defined approaches seeing a surge in popularity now despite many of the fundamentals being described since years already?  In this tutorial we may not provide the ultimate answers to all of those questions. We will review existing definitions and approaches as well as underlying common concepts across them. Based on experience from real-life deployments we’ll be able to share design considerations and implementation choices as well as emerging common design patterns. As current real-life deployments and early adopters tend towards incremental innovation and selective combinations of approaches, we will explore combinations of the following concepts:
-        Application Visibility and Control: aims to optimize application experience in an increasingly dynamic and complex environment where applications across private/hybrid and public cloud, voice/video/collaboration demand proactive management of quality of service (QoS) and the paths of application traffic flows.
-        Network Automation: Concepts and lessons learned from the recent steep increase in industry adoption of network-embedded manageability and automation. Review of technologies, current best practices as well as challenges going forward.
-        Autonomic Networking: Based on the groundwork laid by research and academia, early validation and adoption of autonomic networking concepts became a reality.
-        Network Programming: Seemingly contradicting to some, perceived complementary by others – software defined networking and network programming introduce new degrees of freedom to architect how operational procedures and business applications interact with the network.
Background theory and concept presentation will be combined with practical validation and examples to discuss current practice as well as early adoptions and emerging capabilities – from the perspective of Cisco individual contributors and based on Cisco as well as open source and standardized network technology. Current and future work will be discussed, including open questions, interest areas for research collaboration as well as opportunities for practical validation of upcoming concepts.

TUTORIAL T3 – Configuration, Management and Enablement in a Software Defined Platform
Date and Period: Monday PM, May 5, 2014
Speakers: Salman A. Baset, Theo Benson, Sambit Sahu
Room: Gamma 1

Cloud computing has evolved tremendously to become a truly viable virtualized platform for enterprise applications and services. These large-scale virtualized platforms often need complex configurations – both static and dynamic – at compute, storage and network resource levels to meet various demands from application and services. Configuration, enablement and management of such dynamic and virtualized resources and services pose significant research and engineering challenges. Towards these, several interesting areas have evolved such as automated and dynamic configurations, software defined networking, and management across layers for dynamic workloads. 
Building upon the following three highly successful tutorials, 
1.     “Provisioning and management of Enterprise Services in a Cloud”, IM 2011
2.     “Cloud Enablement Services: Technologies and Challenges”, NOMS 2012
3.     “Leveraging Cloud for Extreme Scale Applications”, IM 2013 
This proposed tutorial will focus on the configuration, management and enablement of cloud services in a software defined platform, covering both hands-on technologies as well as recent advancements in these areas. 
This tutorial consists of three parts.  
1.     Configuration and management of software defined platforms
2.     Enablement and management of applications on software defined platforms
3.     Software defined networks for supporting various workload requirements  
The first part will introduce the configuration and management of large-scale software- defined platforms through automation. We shall describe Chef and Puppet, the industry standard tools for automating deployments, and give an illustration of deploying an OpenStack-based cloud using Chef in multiple configurations including software-defined networking. We will also illustrate the need and us of Chef-based solutions for continuous deployment in such platforms (e.g., weekly consuming OpenStack code directly from github). We will also describe how public cloud providers such as Amazon are using Chef tooling to construct “Opsworks Service” for rapid configuration and deployment of services. The second part of the tutorial will focus on the enablement and management of various set of applications and workloads on such software defined platforms. We shall describe the challenges posed by applications in such platforms and recent advancements in supporting application deployment, monitoring and dynamic workload managements. We shall provide hands-on exposure through various tools and services such as Amazon CloudFormation, OpsWorks, Storage Gateway, Redshift etc. The third part will introduce in detail how recent advances in software-defined networks are enabling deployment of new applications and migrations of existing applications into the cloud. Through OpenStack Neutron (the software defined networking component in OpenStack), we will introduce the architecture and features, which allows rapid creation and deployment of SDNs, connecting them to VMs, and deploying applications in these VMs. We will also discuss in detail some of the techniques on debugging SDNs in OpenStack, learned through operational experiences in production deployments.

TUTORIAL T4 – Wearable Computers: a Holistic Design Approach
Date and Period: Monday PM, May 5, 2014
Speakers: Roozbeh Jafari, Hassan Ghasemzadeh
Room: Gamma 2

Wearable computers bring to fruition many opportunities to continuously monitor human body with sensors placed on body. They provide new avenues to continuously monitor individuals, whether it is intended to detect an early onset of a disease or to assess the effectiveness of the treatment. In the past few years, the community has observed a large number of applications that have been developed using wearable computers. Yet, not many have been deployed in a large scale. There are still several challenges that need to be addressed before realizing the ubiquitous use of wearable computers.
In this tutorial, we present a review of wearable computing systems and their applications. We highlight several components of wearable computers including signal processing, software, hardware architectures, sensors and actuators. We will in particular review signal processing techniques suitable for time-series data acquired from wearable sensors namely dynamic time warping and hidden Markov models. We provide a review for existing software platforms for wearable computers along with the current state-of-the-art hardware architectures. We emphasize the need for holistic approaches optimizing and enhancing the performance of wearable computers (e.g., reducing their form). We will review several cross-layered techniques aimed at creating hardware accelerators for wearable computers. We will conclude the talk by highlighting opportunities and future directions in wearable computer design.
