Who’s Who
 Azure’s market penetration
 Up from 20% to 34%
 AWS has remained flat, (data before S3 outage)
 Google and Kubernetes is gaining interest in the market
 Rackspace still owns some of the landscape
 Oracle is making headway in the SaaS arena, (Software as a Service)

Cloud by Provider
Cloud Endure 2017
Trivia: Which Cloud
Vendor benefitted most
from the Amazon S3
outage?
Amazon
Microsoft
Google
IBM
Oracle
Other

Amazon Web Services
• Owning the space
• New innovations
• New Migrations tools
• New Performance tools

Microsoft
• Incredible percentage of business from:
• Database
• Application
• Bare Metal

Google
 CloudSQL = MySQL and PostgreSQL
 Cloudspanner = RDBMS
 Cloud Bigtable = NoSQL
 Kubernetes is gold!

Oracle Cloud(s)
 IaaS, PaaS and SaaS, oh my!
 Bare Metal
 Playing catchup
Trivia: What year
did Larry introduce
the Oracle Cloud?

Oracle’s Sweet Spot
Software as a Service

Rackspace??
Moving from being a cloud provider, to supporting your cloud choices.

Why Move to the Cloud?
Savings!!
 Cost
 Resource
 Storage
 Time
Well, that depends on….
 Price per Gb
 Complexity
 SLAs
 Minimizing Data
Footprint
 Removing Data-in-
Flight

Sticker Shock
 Estimates on Wasted Cloud Expenditures
 Reports state that 30% of cloud is wasted
 When measured, it was closer to 45%
 Best Tool to Impact Waste?
 Docker
 Vmware Vsphere leads with 42% adoption
 Azure Pack/Stack is private cloud that shows significant growth from 10-14%
 Cloud vendors profit from vendor lock-in.

 Just copy data and applications into the cloud…
 Straightforward approach
 Inefficient, non-incremental for large environments
 Insecure, physical file transfers
 A truck, (yes, I’m looking at you, “snowmachine”)
 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
How Are Companies Migrating to the Cloud?

restore- Assumption

Migration Complete?
 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.

Network, the New Bottleneck
 Few tools identify network latency in terms of percentage or
cause.
 Explore potential latency between cloud services and data
transfer conditions on contracts.
 Negotiate requirements before the agreement is signed and
data is handed over.
 Many organization are investing in a dedicated WAN for cloud
environments and operations.

Cross Platform Migration from AWS

https://www.slideshare.net/AmazonWebServices/dat205-new-launch-introduction-to-aws-database-migration-service
 Replicate data in on-premises databases to AWS
 Replicate OLTP data to Amazon Redshift
 Integrate tables from third-party software into your reporting or core
OLTP systems
 Hybrid cloud is a stepping stone in migration to AWS
Amazon Cloud and AWS Choices

 T2 pricing starts at $0.018 per Hour for T2.micro
 C4 pricing starts at $0.154 per Hour for C4.large
 50GB GP2 storage included with T2 instances
 100GB GP2 storage included with C4 instances
 Data transfer inbound and within AZ is free
 Data transfer across AZs starts at $0.01 per GB

Cloud Projects

What’s Missing?
Over 90% of cloud projects don’t
perform a preliminary identification of
latency or data issues that will impact
the project.
No strategy to identify or optimize BEFORE migrating to the cloud.

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

If you don’t optimize for the cloud before you migrate..
 Different cost structures will come back to bite you-
 Much smaller storage footprint
 Update data-transfers between systems/applications
 Virtualize environments that have high percentage of
duplicate data
Why is there a Sticker Shock with the Cloud?

Traditional copy data management techniques
 Developed without concerns about infrastructure chargeback
 Nightly batchload ETLs
 Traditional data pulls
 Inefficient applications with thick database design
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.
Cost Structures?

Why Less Focus on Thin Provisioning
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
Network-attached storage data transfers offset somewhat
 Most non-production usage modifies or accesses only a tiny
proportion of the total database during lifetime

Cloud and Performance
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- The AWR,
(Automatic Workload Repository) is your friend!
 Take advantage of cloud monitoring tools that can ease the learning
curve as you migrate to the cloud.

Solarwinds

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:

29/documentation/opinion-recommendation/files/2014/wp216_en.pdf
Confidential data

Confidential data
Exposure
Production
Non-production

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.
Why Masking is Important-

Solution

Virtualize and tune on-prem
Mask data before it’s in the cloud
 Smaller footprint before its in flight.
 It’s transformed by securely masking on-premises...
 Then...
 securely virtualized data can be safely replicated to IaaS
Target Complete Solutions to Ease Management and
Vulnerability

 Watch for Chargebacks
 Data in flight
 Minimize data footprint
 Use a cloud monitoring tool to simplify management.
 Confidential Data
 Data masking is often integrated with products and protects PCI,
PII, HIPPA and other confidential data.
