 Copy Data Management: Virtualized sanity for the DBA
Realist.
 Provisioning: Patching, refreshing and if you
ask me one more time!
 Cloud: Cloudy with a chance of failures.
 Security: Yo Developer- Is that the SA password
taped to your monitor??

4. The Life of a DBA
 Provision Databases
 Refresh and provide data to reporting, testing
and development
 Secure database environments
 Optimize data access
 Collaborate to solve business challenges

5. #SQLSatATL
What is Copy Data Management, (CDM)
The management of all non-production databases.
 Broad Term- Physical and virtual clones
 Managed or unmanaged
 Command line or User Interface, (or both)
 Administrative, Infrastructure, security

6. #SQLSatATL
 Storage costs
 Thin-provisioning storage avoidance
 Data transfer costs
 Far less data transferred during provisioning/refresh
operations
 As opposed to the volume of data transferred using
traditional cloning techniques
 Simplifies Provisioning vs. archaic processes to copy data
Why Use Virtualization for CDM?

13. #SQLSatATL
• Using any storage and only fraction of space
• Syncs with native or third-party SQL Server backups
• Can maintain two weeks of data changes
• Managed just like any SQL Server database
• Users can instantly provision a read/write virtual copy
of a database
• Can be used for replication, mirroring, and change data
capture (CDC).
This is Data Version Control

Patching and Upgrading Databases
 Each patch, would need to be applied to a
development database, requiring outage
to development teams and then tested
before applying to test, UAT and then
onto production.
 This has to be performed to EACH
environment, every SQL Server, each
quarter.

CRM
UAT Test DevProd

22. #SQLSatATL 22
 Downtime for valuable resources.
 DBAs working afterhours
 Each database must have it done and…
 The tedious task must be performed over and over
again.
 Little opportunity for advanced learning.
 Each database may experience different bugs.

• I didn’t have to take away a valuable resource’s database environment to test
the patches.
• I didn’t have to apply the patches to subsequent environments, as they are
virtualized copies of the source, simply requiring a refresh from production,
post final patch.
• I save significant time that commonly has to be allocated to quarterly and
annual maintenance for patching.
• I apply the patch twice- once to test, once to production. I only need to
refresh my environments after I’m done.
• For releases, this can be “containerized”, simplifying release and if required,
rollback.

The quickest way to complete a task is not
having to do it.

30. #SQLSatATL 30
The CLI, (Command Line Interface) for CDM should be robust and able to incorporate into DevOps
What if I’m Retro- Command Line?
• The name of the VDB you want to create
• The group in which to create the VDB
• The Oracle database name
• The Oracle database unique name
• The Oracle database instance number
• The Oracle database instance name
• The source dSource or VDB from which you wish to provision
• The SCN or timestamp of the point you want to provision from, (commands can be run
to get the list of snapshots or timeflow ranges.)

31. #SQLSatATL 31
https://docs.delphix.com/display/DOCS43/CLI+Cookbook%3A+Provisioning+a+VDB+from+a+TimeFlow+Bookmark
Choose Source Snapshot:
>snapshot list database=<dbname>
timeflow ”<dbname>" timeflowRanges;
commit;
Create A Virtual Database:
>database provision;
delphix database provision > defaults
delphix database provision defaults > set
container=<Vdbname>
delphix database provision defaults > commit;

32. #SQLSatATL 32
What a CLI Scripted Refresh Looks Like
> database
> select <VDB name>
> refresh
> set timeflowPointParameters.type= (one of TimeflowPointBookmark,
TimeflowPointBookmarkTag, TimeflowPointLocation,
TimeflowPointSemantic, TimeflowPointTimestamp as appropriate)
> set timeflowPointParameters.location= (the location, timestamp,
or bookmark you wish to refresh to)
> set timeflowPointParameters.timeflow= (the timeflow associated
with location)
> commit
This can all be called via a Powershell script…

33. #SQLSatATL 33

34. #SQLSatATL 34
• Monstrous deployments, (20+) benefit from a scripted, CLI option.
• Single or several VDB deployment.
• When investigating deep level issues, using the CLI can make details
easier to search through.
• When looking for “just the facts”, then a graphical UI is beneficial for high
level error messages.
• Self-service has great benefits and make it simple for those without deep
level skills to take advantage of virtualized environments for development
and testing.
• The CLI helps with DevOps automation and orchestration.
When Do I USE the CLI or Graphical UI?

36. #SQLSatATL
Just copy data and applications into the cloud…
• Straightforward approach
• Inefficient, non-incremental for large environments
• Open-source “bcp” uses encryption, compresses,
and multi-threads
• Archaic processes recommended by vendors
Start with backups to IaaS storage, then populate re-hosted
applications by restoring from those backups
• Cloud backups are easy, known technology

Migration Complete…Not so Fast…
• What if you only want dev and test in the cloud.
• Data is migrated, but this doesn’t count for ongoing data loads, application
connectivity across the network.
• To refresh will take considerable time to perform with traditional tools or cloning
methods.
• Rarely a consideration for the difference in cost structure for processing large
amounts of data from on-premise to the cloud.

Cloud Performance

42. #SQLSatATL
https://docs.microsoft.com/en-us/azure/sql-database/sql-database-cloud-migrate
• Database must be MSSQL 2005 or higher, (easy)
• Ensure that the database is compatible with Azure SQL DB, (correct any incompatible
functions, etc.)
• Must have identified all performance issues that will be impacted beforehand.
• Ensure there is as little physical distance between the cloud data center and bacpac files to
be used for migration.
• Disable management jobs that will hinder migration processing.
• Drop any objects or historical data that can impact migration time and can be performed
post migration.

43. #SQLSatATL
• Performs assessment of IIS environment and creates report of what can be migrated.
• Creates report to document what will require moving and any issues identified.
• Creates any websites and associated databases in preparation for the migration.
• If non-compatible products are in use, (which is in case of 90% of environments) then those
must be addressed manually.
• The tool is free to start, but will cost as project proceeds in duration.

Much Improved Option-
1. Data virtualization
Easy, secure, revolutionary
Optimized for faster agile development and testing
Optimized for new costing structures in IaaS
With a software appliance, no concerns about hardware or
software outside of virtualization lock-in.

Optimized for the cloud in the first place…not after!
Different cost structures
Much smaller storage footprint, much less data-transfer
How Does Data Virtualization Enhance
this?

49. #SQLSatATL
Traditional copy data management techniques
Developed without concerns about infrastructure chargeback
This corresponds to higher cost.
IaaS vendors monitor storage and data transfers
Help meet SLAs, garner profits
It’s not just the data that exists in the end, so transformations can
equal big money for cloud vendors.
Different cost structures

50. #SQLSatATL
Know Thy Enemy…
• Tune SQL and Apps to perform efficiently as possible- natural
life of database is growth, (in processes, resources, etc.) before
migrating.
• The less network latency, the better- network tracing to
eliminate database blame is important.
• Many of the same tools and data provides value- DMVs provide
data internally to SQL Server.
• Look at management tools such as Cloudmonix, (formerly
AzureWatch) AppDynamics, Dynatrace, Zabbix or Logic Monitor.

51. #SQLSatATL
For Non-Production Systems…
Change the way you’ve always performed tasks.
Performing common tasks the same way as previously might
end up costing more.
Secure Data
All IaaS alternatives promote encryption for data in-flight and
for data at-rest, but encryption may not be the right
answer…
Secondary Considerations

52. #SQLSatATL
All IaaS solutions provide encryption in-flight and encryption at-rest
But encryption doesn’t protect data as much as it needs to be .
Europe already requires data masking, not just data encryption for any
confindential data, (GDPR):
http://ec.europa.eu/justice/data-protection/article-
29/documentation/opinion-
recommendation/files/2014/wp216_en.pdf
Confidential data

53. #SQLSatATL
Encryption is reversible data obfuscation, which is very different from
masking data.
• Data masking is non-reversible.
It solves the issue at the data level.
Is authentication and authorization in non-production in compliance with
security goals?
All organizations will soon need to review if critical data in non-
production environments be accessible to developers, testers and
users.
Confidential data

54. #SQLSatATL
Masking personally-identifiable, (PII, HIPPA, PCI, etc.) information
renders it useless from a security standpoint
Resolves both the technical and personal responsibility issue.
The data can be masked before it moves to non-production,
removing unnecessary risk.
Why Masking is Part of the Answer
