4. Before cloud What is the right size of servers for my business needs?
What happens in case of
server hardware failure?
How do I deploy new code to my server?
Which packages should
be on my server?
How can I increase server utilization?
What media should I
use to keep backup?
How can I scale my app?
What size of servers
should I buy?
Who monitors
my App?
How often should I backup my server?
Who monitors
my Servers?
What storage I need to use?
Which OS should I use?
Who has physical
access to my servers?
Do I need secondary
network connection?
Are my server in a
secure location?
How many servers
do I need?
Do I need a UPS?
What happens if the
power goes out?
How often should
I patch my servers?
How can I dynamically
configure my app?
It takes how long to provision a new server?

5. Then came IaaS—table stakes for digital business
What is the right size of servers for my business needs?
How can I increase server utilization?
How many servers do I need?
How can I scale my app?
How often should I patch my servers?
How do I deploy new code to my server?
How often should I backup my server?
Which OS should I use?
Which packages should be on my server?
Who monitors my App?

6. Then PaaS, critical for digital transformation
What is the right size of “servers” for my business needs?
How can I increase “server” utilization?
How many “servers” do I need?
How can I scale my app?

7. Serverless, the future platform for next gen apps
How do I architect my app to become Serverless?

8. What is Serverless? Abstraction of servers Event-driven/ instant scale
Micro-billing
