You can watch the webinar on demand here: https://buff.ly/2RQltuF Digital transformation, even though a cliché, is definitely on top of every CEO's strategic initiative list. At the heart of any digital transformation, no matter the industry or the size of the company, there is an API strategy. Application programming interfaces (APIs) are the connection points between one application and another, and as such, they enable applications to build on each other, extend each other, and work with each other. Taken together, APIs represent a thriving ecosystem of developers that is showing no sign of slowing down. Attend this webinar to learn: • How data virtualization greatly enhances the capabilities of an API • How data virtualization works as a service container, as a source for microservices and as an API gateway • How data virtualization can create managed data services ecosystems in a thriving API economy

5. Digital Transformation
• Digital transformation is a strategic initiative for
most organizations
• The concept reflects technology’s role in strategic
decision-making, with its ability to automate and
simplify business processes, improve customer
relationships, enhance productivity, and cost
savings
• Driven from CEO’s office: Highest level of visibility
& fully funded
• Gartner – 28% of CIO budget in 2018
• IDC – 2/3 of CEOs in global 2000 have digital
transformation in the center of their corporate strategy
• Seen as do-or-die initiative
• “If you don’t, someone else will”

6. APIs – Building Blocks of Digital Transformation
• API stands for Application Programming
Interface
• APIs are the foundations of digital
transformation
• Enable the integration of diverse IT systems,
building more collaborative and self-service IT
environments
• Exposing data and processes as APIs allows
creation of new products and business models
• Create revenues from existing IT assets
• These initiatives have created an API economy

8. Protocols, Protocols
Efforts to standardize communications between applications are not new
• CORBA in the 90’s
• SOA architectures and SOAP web services in the early 2000’s
The explosion of cloud-first initiatives and SaaS applications made REST services
the de facto standard of the 2010’s
• HTTP as the application protocol
• HTTP verbs (GET, POST, PUT, DELETE) to indicate the action on the resource
• Light-weight payloads in JSON or XML
But REST is not a standard, but an architectural approach. Many other protocols
have been created to standardized different parts of this approach
• Consumption Protocol: OData, GData
• Security: OAuth, SAML
• Specifications: WADL, OpenAPI (p.k.a. Swagger)

9. Microservices

10. Down the Rabbit Hole…
• Microservices philosophy:
• Applications should be built from small,
modular, lightweight, and independently
deployable components (called microservices)
• Microservices are reusable and easily scalable
• Microservices are independently replaceable
and upgradeable
• Microservices can use different languages and
technologies
• The are typically exposed as RESTful Web
Services

11. Microservices and API Management
To keep microservices lightweight and easily scalable:
• Move security and management out of the service container
API Management Layer
• Security policies
• Access Controls
• Routing Policies
• Service Monitoring
• Service Throttling
• Caching

12. Functionality of API Management Tools
1. Automate and control connections between an API and the applications that use it.
2. Ensure consistency between multiple API implementations and versions.
3. Monitor traffic from individual apps.
4. Provide memory management and caching mechanisms to improve application
performance.
5. Protect the API from misuse by wrapping it in security procedures and policies.

14. Data Virtualization in the API Ecosystem
Data virtualization platforms like Denodo
can play a significant role in an API
ecosystem.
Let’s review three common architectures:
1. Data Virtualization as a Data Service
provider
2. Data Virtualization as an abstraction
data layer form Microservices
3. Data Virtualization as an API
Management tool

16. 1. Denodo as a Data Service provider
Denodo provides one-click, zero development REST web services on top of any data
model
Flexible web services with full-fledge capabilities:
• Support XML, JSON, RSS and HTML
• Support for hierarchical structures
• Authentication with basic HTTP, SPNEGO (Kerberos), OAuth 2.0 and SAML
• Self documented with OpenAPI (pka Swagger)
• Available in Denodo’s REST format, OData 2.0 and OData 4.0
• Navigation to related resources via links and $expand operator
• IDU support with different HTTP verbs (GET, POST, PUT, DELETE)
• Support for READ via POST to handle large input parameters
• Support for CORS and JSONP

18. 2. Denodo as a Data Service provider
Denodo can serve as an abstraction between the microservice implementation and
the data access to simplify its development
• It enables technology changes in the backend without affecting the code of the
Microservice (e.g. legacy system migrations, vendor switch, etc.)
Microservices principles avoid performing data integration at the Microservice itself
• Using DV as a backend enables the independence of the Microservice from the
integration techniques
• The integration logic is performed in the DV layer in the form of virtual views
Although potentially each Microservice could have its own DV backend, a logical
separation per microservice (a schema) is usually a more realistic architecture

3. Denodo as an API Management Tool
Other Enterprise
Applications
Microservices

20. 3. Denodo as an API Management Tool
Since external APIs and web services can be registered in Denodo as data sources,
Denodo’s capabilities can act as a sort of API gateway:
• Centralized authentication and authorization
• Monitoring and access auditing
• Resource allocation policies (e.g. max 10 queries per hour for userA to
service)
• Unified catalog
• API integration
However, keep in mind that is not an API gateway per se, and it may significantly
change the structure and capabilities of your external APIs when exposed through
the virtual layer

Get Smarter – Online Education
22
GetSmarter implemented a
microservices architecture working in
tandem with the Denodo Platform, to
streamline data access across the
organization.
With the Denodo Platform in place,
GetSmarter could provide data to
stakeholders from any microservice
or legacy system, in real time,
without causing any disruption in the
business flow.
Not only did the new architecture
provide the single view of core
entities, it also enabled GetSmarter
to migrate data from legacy systems
behind the scenes, without users
being aware of the change.
