aws journey through the aws cloud: disaster recovery

Journey through the Cloud:

Disaster Recovery

Ian Massingham – Technical Evangelist @IanMmmm

Common use cases & stepping stones into the AWS cloud Learning from customer journeys

Best practices to bootstrap your projects

Journey through the cloud

Explore and learn about AWS with a ‘non-production’ use case Phase systems into ‘live’ DR use with reduced risk

Benefit from lower costs & only pay for what you use Gain the ability to test DR procedures more frequently

Invoke DR whilst testing DR procedures if necessary

Agenda

Why AWS for Disaster Recovery?

AWS is used in a variety of ways… AWS & Disaster Recovery

Fast, secure and cost effective backup and DR for Oracle Apps

“Using AWS has enabled us to move into a whole new market, while lowering our hosting

costs by 80 percent”

“Using AWS allowed us to implement a disaster recovery strategy at a fraction of the cost”

Galata benefits from increased DR scalability, flexibility and reduced

complexity

You might be able to: Business & technical drivers

Reduce costs

Slash DR budgets by up to 50%

Reduce on-premise

Eliminate 30%+ of on-premise physical equipment

Consolidate sites

Eliminate the need to run a secondary site

Remove aging technologies

Eliminate tape for backup and

archive

DR is part of a wider set of policies and controls… DR & business continuity

High availability Backup Disaster recovery

Keep your applications running 24x7

Make sure your data is safe

Get your applications and data back after a major

disaster

DR is part of a wider set of policies and controls… DR & business continuity

It’s not an all or nothing thing

Choose what needs to failover and what does not Some things more important than others

Some things will still be working

High availability Backup Disaster recovery

Keep your applications running 24x7

Make sure your data is protected and can be recovered if it is lost

Get your applications and data back after a major

disaster

Each set of IT assets will have different requirements… DR & business continuity

Recovery Time Objective (RTO)

How quickly you need this asset to be recovered?

e.g. 1min? 15min? 1hr? 4hrs? 1day?

Recovery Point Objective (RPO)

How ‘fresh’ the recovery must be for the asset?

e.g. zero data loss, 15mins out of date?

Assets will sit on a spectrum of technical complexity… DR & business continuity

Rebuild when required from offsite backup

Run hot-hot configuration with

auto-failover

Common DR architectures

4 main patterns Common DR architectures

Backup & Restore Pilot light

Warm standby in AWS

Multi-site solution in AWS & on-premise

We’ll focus on 2 of them… Common DR architectures


Warm standby in AWS


Let’s start with Backup & Restore Common DR architectures


Warm standby in AWS


Advantages to starting a journey with this pattern Backup & Restore pattern

Simple to get started

Easy starting point for exploring the AWS cloud

Low technical barrier to entry

Focus on incorporating cloud into your DR strategy, not on complex technical issues

related to hot-hot systems

Cost effective

Very high levels of data durability at low price

Cost of storing snapshots in S3

Archiving possibilities beyond tape using Glacier

The preparation process… Backup & Restore pattern

Take backups of current systems

Store backups in S3

Move to long term archive in Glacier

The process… Backup & Restore pattern

Take backups of current systems

Store backups in S3

Detail how you will restoring from backup or recover from archive

Move to long term archive in Glacier

Glacier Long term durable archive

Long term Glacier archive

Durable Designed for 99.999999999%

durability of archives

Cost effective Write-once, read-never. Cost effective for long

term storage. Pay for accessing data

Let’s look at the Pilot Light pattern… Common DR architectures


Warm standby in AWS


Moving along the DR spectrum… Pilot light architecture

Build resources around replicated

dataset

Keep ‘pilot light’ on by replicating core

databases

Build AWS resources around dataset and leave in stopped state


Build resources around replicated dataset

Scale resources in AWS in response to a DR event

Start up pool of resources in AWS when events

dictate

Match current production capacity through auto-scaling policies
