Motivations for the Transition to Cloud
New Capabilities and Reduced Cost
§ Lower cost of operations (automation)
§ No up-front HW investment
§ Access from anywhere
§ Flexibility to upgrade capacity
§ Less dependency on desktop software
§ Ease data sharing & monetization

Approaches to Cloud Transition
1. Rehost
§ Move data as is to the same system, but hosted in a cloud provider
§ For example, from on-prem Oracle to Oracle RDS in AWS
2. Replatform
§ Move data as is to a new cloud-native system
§ For example, from an on-prem Teradata EDW to Snowflake
3. Refactor
§ Move to a new cloud0native system, but taking the opportunity to also change schemas,
data structure, ingestion and reporting tools, etc.
§ Changes not just in the systems, but in the data strategy itself

7. 7
Why cloud migration is a headache?
Misestimate Risks
§ Lengthy migration (~15 months)
§ Sovereignty
§ Costs control
§ Regulatory compliance
§ Re-development, drop of productivity
New challenges
§ Security
§ Network latency
§ Minimizing vendor lock-in risk
§ Existing challenges in data management still apply!

8. 8
The Data Strategy as part of the Transition to the Cloud
§ A complete change in architecture is a complex process,
that modifies multiple elements in the data ecosystem
§ However, it guarantees that the data strategy evolves and
follows new trends
§ It’s not just a change in RDBMS vendor
§ It addresses existing challenges and limitations of the existing
data strategy
§ A change of this caliber implies longer projects with
intermediate stages
§ It can last years
§ It involves intermediate (or permanent) hybrid states, where
cloud and on-prem systems coexists

9. 9
What Pieces are Involved in a Strategy Change?
§ Adoption of cloud-based SW solutions
§ AWS, Azure, Google offer cloud alternatives for most common software
§ Some companies have developed specialized cloud-based solutions, like Snowflake, Databricks, Looker
§ Traditional on-prem software has been adapted to the needs and requirements of cloud deployments, like
Tableau and Denodo
§ Adoption of new approaches to data management (e.g. Data lakes, streaming) that adapt to new
trends and requirements (predictive analytics, machine learning, etc.)
§ Migrate to SaaS options for packaged applications
§ For example, migrating from an on-prem CRM to Salesforce.com, marketing tolos, etc.
§ Extended use of web APIs for application-to-application communication
§ New authentication and authorization systems based on Identify Provides (SAML, OAuth, OpenID,
etc.)
§ And many more

13. How Data Virtualization can help
with transitioning workloads to
the Cloud

14. 16
The Value of a Data Delivery layer
§ For Business Users
§ Simplicity: users don’t need to navigate the complexity of the architecture. Where is data (on-
prem, cloud, multi-cloud)? How to Access it? Which location has priority?
§ Agility: all data is securely delivered from a single (virtual) system
§ Accessibility: data is accessible in a variety of formats (SQL, REST, OData, GraphQL) and in a
web-based Data Catalog, regardless of original format and location
§ For IT
§ Abstraction: decouples storage and processing engines from the delivery of data
§ Flexibility: allows IT to change technologies and move data without service interruptions
§ Security: centralized governance and security controls for all data assets

15. 17
As a Global Strategy
For the first time, a technology allows you to
define and implement a data delivery strategy
§ Independent from the sources where you
store and process your data
§ Independent from the consuming
applications
§ Independent from the location of the
deployment
§ Can enforce security and access policies
§ Provides strong governance management

16. 18
Avoid expensive Cloud ‘data egress’ charges
§ Public cloud providers charge every time you move data from their cloud storage to your on-
premises storage. These Egress fees can add up. But no charges for Ingress
§ Transfer within the same regions or availability zones (AZ) is free
§ For some services, the cost for moving data in / out is accounted for in the cost of the
service itself, rather than billed as a separate data transfer fee.
Recommendations:
§ Keep Denodo server closer to the data sources (minimize data movement)
§ Multi-Location architecture helps with faster integration.
§ Ability to cache your active data on-premises, thus avoiding Cloud data Egress fees.

17. Data Virtualization patterns in
cloud architectures

18. 20
Use Case: Virtualizing to Accelerate Data Integration
DV becomes the common Access layer for both on-
rem and cloud systems:
§ Access to all data from a single system
§ Data can be accessed straight from the original
systems, without the need for an additional copy
§ Data can be easily replicated and cached if
necessary
§ Simplifies the combination of data, regardless of
original format and location
§ Enables the definition of semantic models,
independant from original formats and structures
§ Adds advanced security settings to all data

19. 21
Use Case: Virtualizing to simplify migrations
§ Migrations of key systems are complex
§ Normally involve multiple phases
§ Can last months or years
§ Data Virtualization, thanks to the
decoupling and abstraction capabilities,
simplifies the process:
§ Shields the consumers from changes in
the backend
§ Allows IT to move data from one system
to the other without changes in the
consuming applications

20. 22
Use Case: Virtualizing to Acceleart and Reduce Cost
§ Data Sources charges based on usage or data volumes. For example:
§ Snowflake charges by “compute credits”
§ Athena by bytes scanned
§ Smaller summaries mean less data processed and less CPU time
§ Summarized queries are not just faster, but also cheaper
§ Until now, these technologies were only available in some reporting tools
(BO, Microstrategy) and on-prem EDWs (Oracle, Teradata)
§ No cloud-based RDBMS includes these capabilities
§ Denodo supports aggregate-aware query acceleration regardless of consuming
tools and source capabilities
