HOW DO THE TERMS FIT IN YOUR LIFE-CYCLE?

DESIGNDEPLOYMANAGE

7

TO DEPLOY AND DELIVER APPLICATIONS RELIABLY, AT SCALE

RESULTING IN NEW REQUIREMENTS FOR IT

• Programmability(“Infrastructure As Code”)

• Elasticity (Which Demands A Scale-Out Architecture)

• Economics (Steers Towards Standard Servers + Software)

• Strong Instrumentation And Telemetry Of Infrastructure Layer

CLOUD NATIVE PLATFORM REQUIREMENTS

SELF HEALING | MULTI-CLOUD SUPPORT

INTEGRATED LOGGING

APPLICATION PERFORMANCE MANAGEMENT

SELF SERVICE | POLYGLOT LANGUAGE

AUTO SCALING | CONTAINER MANAGEMENT

HOW CAN YOU

APPROACH IT?

Standardized

Built-in Availability and Security

Automate & Simplify Operations

Many Applications

Buy-focused

TWO TYPES OF CLOUD NATIVE PLATFORMS

Ultra-Flexible

Multiple Configurations

Platform = Core Competency

Few Applications

DIY-focused
