The Ever Changing Cloud


Cloud Computing’s Perfect Storm• Growth of internet usage

• Broadband

• Video, voice over IP

• Mobile and Wireless• Anytime, any device

• Smart, IP-connected devices

• Technology tipping point• Moore’s Law driving down costs

• Everything becoming digital

• Explosion in applications and data


Apps are everywhere, across every kind of device placing new demands on IT departments and infrastructure


Data is getting Big: Volume, Velocity, Variety

• Social data and real-time processing of data streams• Customer buying behavior

• Recommendations from social network

• Wall street market feeds analyzed in real-time decision making systems

• Complex event processing (CEP)

• System and Network operational data• Dynamic resource allocation

• Scale up/down services

• Re-route traffic

• Data storage models are changing• Object Store

• NoSQL alternatives

• In-memory databases, caching, SSD’s


Virtualization, cloud computing, and massive scale are all driving major changes in networking

• Data center traffic between servers within the data center is much larger than that which leaves it

• Edge of the network has moved onto servers in the form of virtual switches connected to virtual machines

• Networking services such as firewalls, load balancers, vpn’s, may be virtualized and deployed anywhere in the network

• Virtual overlays, tunnels, provide logical, isolated sub-networks in a multi-tenant shared environment

Open Source Is Where “Standard” Cloud Infrastructure Will Be Defined

Open standards [require] multiple providers, access to code and data, and interoperability of services.

The obvious solution is an open source reference model as the standard.

Potential examples of such would be the OpenStack effort.

- Simon WardleyFrom “A Question of Standards”

http://blog.gardeviance.org/2011/04/question-of-standards.html


• OpenStack is open source software for building highly scalable public and private clouds

• Started in July 2010 - initial contributions from NASA and Rackspace, now foundation-led with over 180 companies now participating

What is the network abstraction we need for developers without bringing all the data

center complexity into the application world?


Original Cloud Computing Model

• Compute service (EC2): virtual machines• Specify vCPU, Memory, Disk

• Launch instance (image, mem_size, disk)

• Suspend, clone, migrate

• Storage service (S3, EBS): virtual disks• Specify storage amount, access rights

• Store object

• Create/attach block

• What to do about networks?

Software API’s for enabling a “conversation” between the application and infrastructure

Application, “I would like certain resources (of type …)certain virtual topologies, specific services”

Lower levels provision physical or virtual resources, setup configuration, and provide information back

OpenStack Quantum Service

• Span multiple data centers?• Network security, policies?• Notion of a network container?

• Best placement of VMs?• Quality of service?• SLA guarantees?

Cisco at OpenStack Summit

OpenStack plays an important role as part of the Cisco Open Network Environment strategy to deliver infrastructure programmability to application developers in the cloud. This week we are announcing:

• OpenStack Cisco edition: This is a community packaged version of the OpenStack Folsom release with open source components for production deployments, such as high availability, monitoring, and networking enabled by Cisco using Quantum.

• Integration of Cisco Intelligent Automation for Cloud with OpenStack Cisco edition, Essex, and Folsom through a multi-cloud accelerator kit: The new multi-cloud accelerator kit extends Cisco Intelligent Automation for Cloud support for OpenStack and provides the ability to manage multiple virtual environments including Amazon EC2, VMware vCloud, Red Hat RHEV, and Citrix XenServer.

As Cloud Computing Continues to Change..• What are the services which will accelerate application

development and deployment?

• Can we achieve the benefits without the complexity?

• What are the important abstractions?

• What is exposed to application developers, what is hidden?• Specialized processor capabilities, e.g. GPUs?

• Networks, subnets, routing?

• VM Placement, Geographic location, region?

• Access to physical network services (load balancers, firewalls, etc.)?

• How can we allow for future innovation in infrastructure?

Thank you.
