Looking for an orchestration taxonomy

In recent years, there have been a number of discussions around the subject of orchestration as a key enabler for different Cloud technologies.

The ETSI NFV Management and Network Orchestration (MANO) working group is defining the main interfaces for resource orchestration, a fundamental layer in management.

It is important to define standard interfaces, but equally important is to understand the main capabilities for an orchestration (or choreography) solution. We can gain some more insight by revisiting previous work, particularly in the domain of Grid computing.

Personally, I found the work done by Ian Foster and Steven Tuecke around IT as a Service (back in 2005, 9 years ago!), still extremely relevant. It is fascinating to see how applicable this work continues to be, apart perhaps from the replacement of general SOA services by REST services in particular. We should pay special attention to their definition of Grid Infrastructure: “enable the horizontal integration across diverse physical resources”. I see their work applicable beyond the physical layer, to logical resources and their composition into services. Quoting the paper, the Grid Infrastructure’s capabilities should be:

  • Resource modeling: describes available resources, their capabilities, and the relationships between them to facilitate discovery, provisioning, and quality of service management.
  • Monitoring and notification: provides visibility into the state of resources to enable discovery and maintain quality of service.
  • Allocation: Assures quality of service across an entire set of resources for the lifetime of their use by an application.
  • Accounting and auditing: tracks the usage of shared resources and provides mechanisms for transferring costs among user communities and for charging for resource use by applications and users
  • Provisioning, life-cycle management and decommissioning: enables an allocated resource to be configured automatically for application use, manages the resource for the duration of the task at hand and restores the resource to its original state for future use. Read More »

Home Gateway CPE Virtualization

Ken Morse1207_-138Contributed By Dr. Ken Morse, Chief Technology Officer of Connected Devices at Cisco

To compete in today’s market, your network needs to support new business models and increase revenue while lowering your operating expenses.  You need a network that is:

  • Agile
  • Comprehensive
  • Open
  • Integrated
  • Extensible

In order to reach these goals the network is increasingly becoming virtualized.  Virtualization is being pursued across the architecture at all different levels — applications and networking functions now become compute workloads – but to fully reach value, virtualization cannot just be discrete implementations but rather needs to be automated and orchestrated together.

The benefits of virtualization are many: Read More »

Next Generation Data Center Design With MDS 9710 – Part I

 

High Speed (16Gbps) and High Capacity (384 Line Rate ports per Chassis)

Data centers are undergoing a major transition to meet higher performance, scalability, and resiliency requirements with fewer resources, smaller footprint, and simplified designs. These rigorous requirements coupled with major data center trends, such as virtualization, data center consolidation  and data growth, are putting a tremendous amount of strain on the existing infrastructure and adding complexity. MDS 9710 is designed to surpass these requirements without a forklift upgrade for the decade ahead.

MDS 9700 provides unprecedented

  • Performance - 24 Tbps Switching capacity
  • Reliability -- Redundancy for every critical component in the chassis including Fabric Card
  • Flexibility -- Speed, Protocol, DC Architecture

In addition to these unique capabilities MDS 9710 provides the rich feature set and investment protection to customers.

In this series of blogs I plan to focus on design requirements of the next generation DC with MDS 9710.  We will review one aspect of the DC design requirements in each.  Let us look at performance today. A lot of customers how MDS 9710 delivers highest performance today. The performance that application delivers depend

4 Key Requirements to Scale the Internet of Things

April 15, 2014 at 8:00 am PST

Today the Internet of Things (IoT) is everywhere: you can easily see smart meters on houses, parking sensors in the ground, cameras attached to traffic posts, and people wearing intelligent wristband and glasses -- all of them connected to the Internet. And this is only the tip of the iceberg: while you are reading this blog post factories, trains and trucks around the world are also being connected to the Internet.

Many traditional industries have historically requested help from different types of engineers to improve their processes and gain efficiency. Now they are asking us, the Internet engineers, to contribute solving new industrial world challenges by connecting billions of new devices.

The more ambitious part of this journey is the integration between both worlds: Information Technology (IT) and Operation Technology (OT). For that a systems approach is required to scale the existing Internet infrastructure to accommodate IoT use cases, while making IT technology easy to adopt for OT operators. We are facing a historical opportunity to convergence massive scale systems in a way we have never seen before, and such an effort will unlock a multibillion-dollar business.

Scaling IoT

In order to be ready to capture this opportunity and scale in a sustainable manner, four requirements are necessary:

Virtualization Meets Video Processing at NAB 2014

If anything is certain about the video business, it’s this: the volume of change is daunting and every change tends to make life more complicated, not less.

This is certainly true at the sharp end of the business -- digital video processing – where  “multiscreen” video, new video formats and new video technologies are together creating a perfect storm of complexity. Once there was SD over MPEG2 delivered to TVs. Now there is SD, various flavors of HD and, soon, 4K; and MPEG2, AVC and now HEVC; plus a wealth of encapsulation schemes and DRMs; And even more screen sizes and resolutions as the number of device to be supported grows ever larger.

The number of permutations of all these options is truly dizzying. Every permutation is a potential video “workflow” to be implemented – and the number of permutations is expanding rapidly, apparently endlessly and it’s exponential. Today Cisco deals with some media companies that have over 80 video workflows for their content. One more video format – for instance 4K – and this potentially doubles to 160. Another compression scheme – HEVC perhaps -- and now we have 320. And so on.

Keeping track of all these “workflows” is one thing, but Read More »
