Internet of Everything is HereNetworked Connection of

People, Process, Data, Things

Connecting people in more relevant, valuable ways

People

Leveraging data into more useful information for decision

making

Data

Delivering the right information to the right person (or machine) at the right time

Process

Physical devices and objects connected to the internet and each other for intelligent decision making

Challenges:

• Manual processes

• Complex handoffs between teams and domains

• Static resource allocation

Business Outcome:

• Days/weeks/months to deploy IT services

• High operational cost

• Rigid silos

• Infrastructure inefficiency and under utilization

Changing Consumer Experience

Automation = Simplicity

Customers are Driving towards Automation :

• Consistency in CONFIGURATION across three technology silos

• Quick TIME TO MARKET for application owners

• Consistency in ACCURACY

• Minimize OPERATING COSTS

• COMPLEX Functions made easy.

• RAPID execution of repetitive tasks.

Simplicity and Automation

Customers are Assuming Simplicity :

• Lack of features

• Possibility of Irrelevance

• Increase Engineering Costs

• Vendor Lock-in.

• Impedes innovation.

How do we manage our network "Today"In a majority of environments:

Stage configuration in Notepad, copy/paste

Automation according to definition of fixed third party tools

Conversational configuration via expect scripts

Challenges:

Scaled Infrastructure

Manual, repetitive, error-prone tasks

Waste time & talent

Network lags behind industry automation capabilities

Pasting large configuration:

Typo? Start from scratch

Summary of the Amazon EC2 and Amazon RDSService Disruption in the US East Region

AWS official statement : http://aws.amazon.com/message/65648/

“The trigger for this event was a network configuration change. We will audit our change process and increase the automation to prevent this mistake from happening in the future. However, we focus on building software and services to survive failures. Much of the work that will come out of this event will be to further protect the EBSservice in the face of a similar failure in the future”.

The originating cause of the disaster was the review of a network configuration (human error).

The Good, the OK & the Ugly of Cloud Architecture

[...] By now, it should have been drilled into everyone’s heads that they need to architect for failure if they want guaranteed high availability from their cloud computing efforts.

(distribution of risk, careful monitoring, analysis and reaction)

http://gigaom.com/cloud/the-good-the-alright-and-the-ugly-of-cloud-architecture/

• The automation capabilities of existing tools is not enough

• Expensive additional tools are required

• Often these tools bring silo-functionality, and they need to be integrated with professional services

• Own custom automation development is too expensive

UCS Is Policy Computing (Stateless)

Stateless computing facilitates much greater scalability and flexibility

• Servers waiting for their identity based on Application needs

• Service Profiles push out configuration to available HW

• Able to pre-provision compute platform

• Policy is the Server – Agile, Flexible, Mobile, and Scalable
