• Fault Tolerant systems are measured by their
Availability in terms of planned and unplanned
service outages for end use.

What do we mean by “Cloud”?
A cloud is a physical
datacenter entity behind an
API endpoint.

What do we mean by “Cloud”?
Think of “Cloud” as a
“resource pool”
accessed via an API.

How would we like to
use “Cloud”?

25. 25#
How would we like to use it?
We'd like to use "Cloud" as a
collection of many
"resource pools"
accessed via one API.

Achieving High-Availability
• Multi-Cloud Cold DR
• Staged Server Configuration and generally no staged data
• Multi-Cloud Warm DR
• Staged Server Configuration, pre-staged data and running Slave Database Server
• Multi-Cloud Hot DR
• Parallel Deployment with all servers running but all traffic going to primary
• Multi-Cloud HA
• Live/Live configuration. May use Geo-target IP services to direct traffic to regional
load balancers

Multi-Cloud Cold DR
Staged Server Configuration and generally no staged data
• Slow to replicate data to other cloud
• Slow to bring database to an operational state
Cloud Management Platform

31. 31#
Multi-Cloud HA
Live/Live configuration. May use Geo-target IP services to direct traffic to regional
load balancers.
• Provides high availability
• Complex to implement and manage

A Cloud “Remote Control”
• Private clouds
• Public clouds
• Hybrid clouds

• Vendors
• Geography
• Price
• Performance
• Compliance

It’s a multi-cloud world
• Not all clouds are created equal
• We want to use benefits from different cloud providers
• Design for failure
• Assume everything will fail and architect a solution capable of handing
each and every failure condition
• Keep your options open
• … like she does
