2012 Definition of Business Resilience

• Business resilience is not confined to the business continuity context– It’s a broader proposition around enabling

organisations to rapidly and proactively adapt to change

– Change in today’s economic climate is the norm – sometimes hourly

• Businesses need to think about how to make their business more resilient and consider the critical role of IT in achieving success

Defining Business Resilience Risks

• To determine business resilience requirements, you need to define your risk exposure:– Internal– External– Operational (e.g. quality control)– Financial– Reputational

• How can you use IT innovation to detect and mitigate these risks?

Impacting Trend: Data de-perimeterisation

• Today, we use smart phones, laptops and tablets– Consumerisation – bring your own device to work policy– Blurring of the edge of the corporate environment– Need a new approach to security and compliance

• Expectations of connecting to the network, accessing virtual desktop seamlessly

• Using smart phones for transactions without understanding the implications for the OS– Corporate and personal exposure to cyber threats

Impacting Trend: How people work

• How do people interact with each other and the business?– People-to-people declining, machine-to-machine (M2M) growing

• Common element is the network– Pervasive, not constrained by buildings/locations– Increasingly a mix-and-match of enterprise networking and software-

led computing/cloud-switching

Impacting Trend: Enterprise consumers

• Three different classes:

– Premise-based workers: access private/hybrid environment across enterprise class network

• Can control network performance to support the applications it needs to run

– Mobile workers: need to empower them to access computing environment in resilient fashion

• 3G• WiFi

– Extranet workers: partner companies supported by point-to-point VLAN• Delivers the equivalent of the enterprise network for ‘community of interest’• Enables authenticated companies to connect securely to shared services platform

without having to build internet pipes

The Role of IT in an 2012 Organisation

• The focus of today’s IT discussions in businesses is on managing core activities rather than ICT infrastructure– “My budget is being frozen/cut, my headcount reduced”– “I need to realign IT to do more for the business”

• IT leaders can’t afford to focus on IT-specific projects for their own sake– Focus should be on those that deliver business value (e.g. improved cash flow) or

competitive advantage

• How do your business challenges/goals map to IT requirements?

Yesterday: vertical IT

• Most IT employs a vertical approach– Top-down, multi-layered environment– CAPEX-based– Budgeted annually– High maintenance cost (premises, disk storage, back-up)

• Requires understanding of single point of failure (Component Failure Impact Analysis)– How quickly can you restore service if anything goes wrong?– How quickly will customers lose trust/supplier resonance?

Today: horizontal IT

• A horizontal approach serves multiple requirements– People talk about public cloud, private cloud, hybrid– People talk about IaaS, PaaS or SaaS– Can be any of these things– Only common characteristic = must be hosted outside the enterprise on a

shared services platform

• Eliminates single points of failure to deliver greater resilience– No need for bespoke deployment of applications and services– Drives economies of scale– Can create the ultimate ‘computing-less enterprise’ like Google

But what about th

e Service aspect?

Gartner say that in

a survey most CIOs are not sure what

they are getting for th

eir money

You need measurable KPIs as targets

Businesses require each service to be tig

htly

controlled

and monitored with an SLA

Gradual shift from Vertical to Horizontal

• Managed service doesn’t mean today v tomorrow– Journey between CIO and service provider to migrate services on a per-

application basis– Requires a good programmatic approach with recommendation and test plans

devised by provider– What are the customer’s priority apps (top 15)?

• Not everything belongs in the cloud– Moving from enterprise-centric ICT infrastructure to hybrid infrastructure

means some apps won’t work• Can be retained in-house• Can be “fork-lifted” to dedicated rack in host environment

What about a wholesale change?

• It is possible to move a customer’s entire IT estate with zero downtime

– Migration performed over a number of weekends– Can be easier to get focused resource behind a major project

(customer and service provider)

– Read more about how this can be achieved by visiting our case studies:
