AGENDA

● Cloud Types And Deployment Models

● Red Hat Cloud Infrastructure (IAAS)

● Red Hat Enterprise Linux Containers and Atomic Host

● Hybrid Cloud for Microservice Cloud Apps

CLOUD TYPES AND DEPLOYMENT MODELS

RED HAT TRENDS AND TECHNOLOGY3. September 2015 - Seite 6 / 25

TRADITIONAL WORKLOAD MODE-1

● Typically resides on a single, large VM● Cannot tolerate any downtime● Need $$ enterprise virtualization tools● Application scales up, not out

CLOUD WORKLOADSMODE - 2

● Workload resides on multiple VMs● Tolerates VM failure● Fault tolerance often built into workload● Application scales out, not up

WORKLOADS ARE EVOLVING

WORKLOAD TYPES

TRADITIONAL CLOUD MIXED/HYBRID

1 Application → 1 VM 1 Application → Many VMs Combination of Traditional and Cloud VMs to provide

application. Database may be hosted on traditional

workloads, web front-end and logic layers on cloud

workloads.

Lifecycle in years Lifecycle hours to months

Not designed to tolerate failure of VM, so you need features that

keep VMs up

If a VM dies, application kills it and creates a new one, app

stays up

Application SLA requires enterprise virt. features (migration,

HA, etc.)

High resiliency features often built into the application itself

Scale up (VM gets bigger) Scale out (add VMs)

Example workloads: Exchange, large

commercial applications

Example workloads: Netflix, most mobile phone applications

MINIMAL, SECURE FOOTPRINT

Minimal host provides “just enough” to support apps.

RAPID PROVISIONING

Apps can be provisioned and started in milliseconds.

SIMPLIFIED MAINTENANCE

Atomic updates are quick, reliable, and can be rolled back.
