Non-Critical Workloads
Only?
Cloud isn t only for Dev / Test,
consider Mission Critical uses
(combined with business continuity
capabilities off-Cloud).

Patterns

Governance
CapEx Zero
Pay per use and subscription
model IT rather than big up
front lump sums.
Flexi-Working
Get to work via the internet,
regardless of location, using
any device.
Disaster Recovery
Robust backup and recovery
without the need for expertise.
Flexi-Scale
Scale up or down, in or out –
operational agility baked in
Maintenance
Automation
of patches, security and
software updates.
Security
As secure as On Premises, with
joint responsibility for defence in
depth. Negate the impact of lost or
compromised devices.
Collaborate!
Share and workflow documents
and data anytime, from anywhere,
updating and sharing a vision in
real time.
Competitiveness
Enterprise-class technology for all. Punch
above your weight or connect dispersed
siloes to create an organisation that s greater
than the sum of its parts.
Cloudy Technical
Perspectives
Overloaded and misused terms
complicate the understanding of
Cloud Platform ecosystems and
their capabilities.
Cloud Everything
...isn t necessarily a sensible strategy, Cloud
may not be right for your business at all.
Consider ICT maturity, TCO, change agility,
budgeting – measure bang for buck carefully.
Migrate to Gain
Lift and Shift migration to the
Cloud doesn t necessarily infer
Cloud benefits – you may need
to rewrite!
Egg Baskets
One Cloud service approach and
one vendor may not be a sensible
strategy, leverage the breadth of
options available.
