Amazon RDS allows you to launch an optimally configured, secure and highly available database with just a few clicks. It provides cost-efficient and resizable capacity, automates time-consuming database administration tasks, and provides you with six familiar database engines to choose from: Amazon Aurora, Oracle, Microsoft SQL Server, PostgreSQL, MySQL and MariaDB. In this session, we will take a close look at the capabilities of Amazon RDS and explain how it works. We’ll also discuss the AWS Database Migration Service and AWS Schema Conversion Tool, which help you migrate databases and data warehouses with minimal downtime from on-premises and cloud environments to Amazon RDS and other Amazon services. Gain your freedom from expensive, proprietary databases while providing your applications with the fast performance, scalability, high availability, and compatibility they need.

2. Agenda
• Why migrate?
• RDS value
• Administering RDS
• Database migrations
• Sierra-Cedar Inc.’s migration
• Q&A

3. Why migrate?
Database management is
expensive. Moving to RDS
reduces management cost,
moving to open source
engines on AWS can reduce
costs by 90% or more.
Proprietary databases
are risky. Moving to
open-source engines on
RDS removes avoidable
risk.
Costs Risks

4. Where do DBAs spend their time?
Application
Optmization
Installation,
Upgrades, and
Patching
Backup and Recovery,
Data Import and Export,
Licensing, Training,
Security

6. DBaaS report
“AWS not only has the
largest adoption of DBaaS, it also
offers the widest range of offerings to
support analytical, operational, and
transactional workloads.”
“AWS’s key strengths lay in its
dynamic scale, automated
administration, flexibility of database
offerings, strong security,
and high-availability capabilities,
which make it a preferred choice for
customers.”

RDS Key Features

9. Automated Backups
MySQL, PostgreSQL, MariaDB, Oracle, SQL
Server
• Scheduled daily volume backup of entire instance
• Archive database change logs
• 35-day retention
• Multiple copies in each AZ when running Multi-AZ
• Taken from standby when running Multi-AZ
Amazon Aurora
• Automatic, continuous, incremental backups
• No impact on database performance
• 35-day retention
Every day during your
backup window, the
RDS service creates a
storage volume
snapshot of your
database
Every five minutes,
RDS backs up the
transaction logs of
your database
If database is Multi-AZ, the snapshot is taken from the standby
• Single-AZ deployment = multiple backup copies in one AZ
• Multi-AZ deployment = multiple backup copies in multiple AZs

10. Scaling instances up/down
AWS Management Console

11. Administering RDS

12. There’s an API for that
• Modify instances
• Instance type
• Storage size/type
• Versions, parameters, options, and more
• Applied immediately or in next maintenance window
• Reboot instances
• Restore instances

17. Snapshots
• Always incremental
• I/O happens in the backend
• Amazon S3  99.999999999% durability
• Inherit encryption
• Copy across accounts
• Copy across regions
• Copy automatic to manual to save

18. Database Migrations

19. Database Freedom
What is it?
• Database Freedom is an initiative to support our customers free themselves from the high
cost and technical lock in of the Oracle Database.
How to determine a good migration opportunity?
• Workload Qualification Framework
Category Workload Type Ease of migration Man-hour consumption
1 ODBC/JDBC workload Easy Light
2 Light Oracle feature workload Easy Medium
3 Heavy Oracle feature workload Hard Heavy
4 Oracle specific application framework Difficult to migrate N/A
5 OCI workloads Hard Heavy

20. Migration Options
If you’re not switching engines and can take downtime:
- SQL Server: bak file import
- MySQL: read replicas
- Oracle SQL Developer, Data Pump, Export/Import
- PostgreSQL: pg_dump

21. What are AWS DMS and AWS SCT?
AWS Database Migration Service (DMS) easily and securely
migrate and/or replicate your databases and data warehouses
to AWS
AWS Schema Conversion Tool (SCT) convert your commercial
database and data warehouse schemas to open-source engines or
AWS-native services, such as Amazon Aurora and Amazon Redshift
We migrated over 30,000 unique databases. And counting…

22. Know before you migrate with SCT Assessment Report
AWS SCT helps with converting tables, views, and code

• Greater agility and flexibility of services to the business
• Improve efficiency of support resources
• Minimize maintenance window downtime
• Leverage automation
Private
Cloud

27. The Journey
Evaluated cloud stack, open stack
Evaluated various cloud providers
All paths led to AWS
• Expanse of AWS services
• Access to APIs to facilitate automation
• Continued investment in the platform
• Responsiveness in addressing issues

28. The Initial Scope
PeopleSoft Financials v9.2
• 5 non-production instances
• 1 production instance
• DB size – 660GB
• 2000+ users
PeopleSoft Human Capital Management v9.2
• 5 non-production instances
• 1 production instance
• DB size – 100GB
• 2000+ users

29. The Dilemma (RDS vs. EC2)
• RDS vs. EC2
• Didn’t like the idea of RDS
• Too restrictive/loss of control
• No direct access to the box
• “It’s doing my job”
• DBAs conducted a full review with an open
mind

30. The Dilemma (RDS vs. EC2)
EC2
● Pros
– Flexibility w/ full access
– Access to the Oracle utilities
(Dataguard, RMAN, etc.)
– Similar to the way it’s managed today
● Cons
– Self-deployed
– High administrative overhead (all
tasks manual - self installation,
patching, backups, etc.)
RDS
● Pros
– Managed Service = reduced
overhead (easy deployment,
automated patching and backups,
etc.)
– Multi-AZ option for HA
– Parameter and Option groups
– Flexible license model with BYOL
option
● Cons
– Don’t have access to all the Oracle
utilities
– One-off DB patching not supported
