This document discusses cloud computing deployment models and best practices. It covers public, private, and hybrid clouds and their key characteristics. Some challenges of moving to the cloud include lack of skills, security concerns, and cultural resistance. Best practices include partnering with local experts and understanding specific business needs before adopting cloud solutions. The document also addresses optimizing cloud costs by eliminating idle resources and rightsizing services. Emerging technology trends point to an increasing convergence of cloud, AI, 5G, and IoT.

Private
Cloud
Provides control
and responsibility
Enhanced levels
of security and
privacy
Hybrid
Cloud
Provides
flexibility
Ability to scale to
the public cloud
Community

PUBLIC, PRIVATE & HYBRID CLOUD
CHARACTERISTICS OF EACH CLOUD

5. PUBLIC, PRIVATE & HYBRID CLOUD
✓ Well suited for hosting development platforms or web browsers, for big data processing that places heavy demands on
computer resources, and for companies that do not have advanced security concerns
Public Cloud
✓Often used by government agencies, financial institutions, any other mid- to large-size organizations with business-critical
operations seeking enhanced control over their environment
Private Cloud
✓Suitable for businesses with a spike in demand such as in retail business where there might be seasonal events and they
can operate in public cloud to tap on additional computing resources
Hybrid Cloud
✓Attractive option for companies in the health, financial or legal spheres that are subject to strict regulatory compliance
Community Cloud
When to use which cloud?

How do we ensure that data stored on the cloud is secure?

7. BEST PRACTICES IN CLOUD
PUBLIC CLOUDVS ON-PREMISE DATA CENTRE
On-premise
data centre
Requires greater time and effort on
securing on-premise data
Network is at risk of physical access by
unauthorised users, especially insider
threats e.g. staff
Hackers may find ways to exploit
flaws in on-premise systems, such as
through phishing emails to collect
employees’ passwords
Public Cloud
Public cloud providers’
profitability and reputation
depend on ensuring that
customers’ data remains secure
Data in the cloud may be stored
on a server physically located
anywhere in the world, making a
physical attack much less likely
Fewer vulnerabilities as cloud
providers are quick to fix issues
to keep data protected

8. BEST PRACTICES IN CLOUD-
WHY SHOULD SMES MOVE TO CLOUD?
• Pay per use is ideal for organisations who are
growingFlexibility
• Cloud protects and backs up data from any
possible data disasterSecurity
• Zero capital expenditure feeCost Optimization
• Ease of scaling up or down depending on your
requirementScalability
• Can be at work anytime, anywhereMobility

9. BEST PRACTICES IN CLOUD
1
Hire the best person if you can afford.
If not, partner with a local company who
understands how to help with your move from
current infrastructure to cloud.
2
Don’t believe that everything can go into the
cloud.
Understand what your business needs.
Don’t follow the move to cloud blindly.

10. CLOUD COST OPTIMIZATION
TOP 4 FACTORS IN UNOPTIMIZED CLOUD COST
• Idle resources1
• Oversizing2
• Zombie assets3
• Under leveraging RIs4

11. CLOUD COST OPTIMIZATION
HOW TO REDUCE CLOUD COSTS
Identify unused and completely unattached resources and
remove themTotal visibility of business assets
Utilize heatmaps to establish start and stop times or
leverage automation to schedule instances to start and
stop, optimizing costs
Starting and stopping non-productionVMs on a
schedule
Select the lowest cost resources which fulfil the
technical needs as Cloud provides the elasticity to
increase the size if needed
Pay-as-you-go
Analyze computing services and modify them to the
most efficient size
Rightsizing,upgrading and migrating data
