Who am I?


Virtualization is the creation of a virtual (rather than actual) version of something, such as an operating system, a server,

a storage device, database, files or network resources.

What is Virtualization?


Virtualization Adoption Trend

.

Source: Gartner Forecasts


This trend will only increase in the next five years as cloud overtakes the industry


Source: Right Scale State of the Cloud 2016

Cloud Adoption


An overall trend in companies that includes autonomic computing, where the IT environment will be able to manage itself based on perceived activity, and resource shared computing, in which computer processing power is utilized and/or paid for only as needed. The usual goal of virtualization is to centralize administrative tasks while improving scalability and work loads.

The Future of Virtualization


Welcome to the New Skill Adoption List!


Savings!!- Cost - Resource - Storage - Time

Why Virtualize?


Why Move to the Cloud?

Savings!!• Cost • Resource • Storage • Time

Well, that depends on….• Price per Gb• Complexity• SLAs and the

biggest savings….

Virtualization


How?1. Just copy data and applications into the cloud…

◻ Straightforward approach Inefficient, non-incremental for large environments Open-source “bbcp” uses encryption, compresses, and multi-threads Archaic processes recommended by vendors

2. Start with backups to IaaS storage, then populate re-hosted applications by restoring from those backups◻ Cloud backups are easy, known technology

How Are Companies Migrating to the Cloud?

Migration Complete…Not so Much…

Even if only development or test has been migrated to 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.

Rarely a consideration for the difference in cost structure for processing large amounts of data from on-premise to the cloud.


On-demand EC2 instances- Range from $0.0065/hr to $8.184/hr

◻ Reserved instances provide discounts from 29% to 75% over on-demand

Storage in Elastic Block Storage- EBS General Purpose SSD (gp2) volumes

◻ $0.10 per GB-month of provisioned storage- EBS Provisioned IOPS SSD (io1) volumes

◻ $0.125 per GB-month of provisioned storage◻ $0.065 per provisioned IOPS-month

- EBS Throughput Optimized HDD (st1) volumes◻ $0.045 per GB-month of provisioned storage

Data transfer in EC2- DATA IN from “internet” is free, but internally within EC2 can be $0.01/GB

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


Optimized for the cloud in the first place…1. Different cost structures

◻ Much smaller storage footprint, much less data-transfer

How does data virtualization enhance the Cloud experience?

= $$$$


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


Data virtualization minimizes…

Storage costsThin-provisioning storage avoidance

Data transfer costsFar less data transferred during provisioning/refresh operations• As opposed to the volume of data transferred using traditional

cloning techniquesNetwork-attached storage data transfers offset somewhat• Most non-production usage modifies or accesses only a tiny

proportion of the total database during lifetime


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:

Confidential data

http://ec.europa.eu/justice/data-protection/article-29/documentation/opinion-recommendation/files/2014/wp216_en.pdf




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


- 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.

Delphix appliances include replication- For data protection, for scalability, and for

migration- Virtualized data is already compressed at-rest,

further compressed and encrypted in-flight, incrementally replicated to another engine

Selective replication of virtual databases and files


Once data has been virtualized on-premises…- It’s transformed cross-platform on-premises...- It’s transformed by securely masking on-premises...

Then...- securely virtualized data can be safely replicated to

IaaS

Data virtualization + transformations = complete solution

• Watch for Chargebacks- Data virtualization minimizes storage and data transfer and

transformation costs.• Confidential Data

- Data masking integrated with data virtualization truly secures PCI, PII, HIPPA and other confidential data.

• Platform- Cross-platform conversion integrated with data virtualization

solves a huge challenge today.
