4. Day 1
What is Cloud
computing and the
benefits of using it?
• Shared, multi-tenant
infrastructure
• Accessible for everyone –
even you personally
• Massive scale and
redundancy
• Economies of scale

5. © Copyright Microsoft Corporation. All rights reserved.
The Azure Global Network

6. Unsurpassed scale and innovation
• 12 Racks, 864 servers
• Enough storage for 1M movies
• No maintenance for up to 5 years

7. Why Cloud?
Cost
CapEx vs OpEx / Pay as you go
Switch it off / Delete it
Scale
DB, VM’s, Storage, IoT
Secure
Loads of services
Basic always-on DDoS +
Reach
Global
High Availability / Elasticity
Autoscale / Manual scale / choose your 9’s
Monitoring
Cloud, On-Prem and other cloud providers
Integrated
Windows, Office, Dynamics

8. Cloud models
Public Cloud
• Resources are owned by the
cloud service provider, but
used by the consumer
• Multiple end-users/
companies make use of the
service
• Publicly accessible
• Readily available (common)
• Connectivity via internet
using mostly a browser
• No deep skills or knowledge
required to setup
Private Cloud
• Owned and used by the same
entity / users
• Owner responsible for buying
the hardware
• Mostly used by a single
organization
• Connectivity is mostly
achieved via VPN or private
network
• No public access
• Requires deep skills and
knowledge to setup and
maintain
• On-prem resources
Hybrid Cloud
• Specific services / resources
run in the cloud; others run
on-prem
• Efficient as existing
resources on-prem can be
utilized
• Organization retains some
level of control
• More skills are required to
build and maintain a hybrid
scenario

9. Shared
Responsibility
Model
IaaS – Infrastructure (VM, Networks, Storage, etc.)
PaaS – Platform (Web/mobile Apps, Containers, IoT, etc.)
SaaS – Software (Office, Dynamics, IoT, etc.)

10. Consumption
model
Pay for what you use
Pay less if SLA’s are not met
Don’t like it, switch it off
Commit to longer, more – save more
Choose the right plan, change if it does not work
Horses for courses (dev, uat, prod)
Capital expense (CapEx)
• Large amount upfront
• Deduct the amount from tax over time
• Capex is an upfront cost
Operational expense (OpEx)
• Smaller, ongoing amounts
• Being billed for services or products that you are
using right now
• No upfront cost – this is a pay-as-you-go model
• Taxed in the same year
