Picking the right cloud platform

Where to Launch?

Angelo Rajadurai

Goal

Find out the need for many clouds. How
do you choose the right cloud that
meets your needs? How do we deal with
the migration issues?

why all this fuss

Drive down cost

Increase Agility

but does one size ﬁt all?


rent VS buy - the car analogy

Buy vs. Rent
$50/day
4x - 5x cheaper than rent ($10/day)

Just pay daily
High cost to acquire (pay upfront)

High time to acquire (days/weeks) Quick (In minutes or hours)

Typically fixed location (home base) Can be rented at almost any location

No maintenance cost (operator
Need to maintain (User maintains) maintains)

Personalized (You pick color etc) Reuse & public (Part of public fleet)


rent VS buy - Some more specialization

Pope Mobile
Taxi

Super quick rental
Super secure buy!


Cloud or Data center

Yes No

Is your demand reasonably constant? Data center Cloud

Can you pretty accurately predict
Data center Cloud
growth?

Can scaling be planned over a period of
Data center Cloud
time?

Is your service delivered to globally
Cloud Data center
dispersed audience?

Is application responsiveness a main
Cloud Data center
concern?


Need for hybrid

Hybrid

Part of my demand is
Is your demand reasonably constant? constant. There are also
sudden spikes

I can predict user growth but
Can you pretty accurately predict growth? want to plan for spikes and
valleys

Can scaling be planned over a period of
No
time?

Many of my services need
Is your service delivered to globally central compute but needs to
dispersed audience? be delivered to a global
audience

Is application responsiveness a main Yes. Many cases where I need
concern? to control hardware types

Why Applications Don’t Perform
Waiting for Data

• Today’s Multi-Core, Multi-Socket
application server design are
increasingly held back by slow
storage
• When requesting data, the server
spends most of it’s time waiting for
storage
• Application performance remain
sluggish regardless of the Server
CPU horsepower
• The traditional remedy of adding
more expensive DRAM may no
longer suffice as data sets double
ever
