API management came about to help companies create and manage developer ecosystems by following in the footsteps of the successful API programs of Twitter and Facebook. Today with mobile apps and new web development based on an API-first strategy, APIs are no longer just a way to power a company's developer program, they're the connective tissue that powers all the interactions with customers and partners across an extended value chain.
Join Ed Anuff and Dilshad Simons to learn the profound technical and business implications of this shifted landscape and to discuss API Management, its shortcomings, recent advances, and real-world deployments.
We will discuss:
- How enterprise APIs create new channels, unlock value of data, and fuel innovation
- The benefits of structuring your development around an API-first platform strategy
- Getting a full 360-view across all your channels of interaction by tying your analytics and business intelligence directly into your API-tier
API management solutions help enterprises manage, secure, and mediate API traffic, ensure that developers and partners are productive, and grow their API programs to meet the increasing demands of a digital world. APIU management capabilities including Backend as a Service (BaaS) solutions, analytics engines, and monetization enable developers to develop and extend apps with modern features, provide deep insights into the APIs, and allow API providers to monetize their APIs and developers to share in the revenue.
Architecting an Enterprise API Management StrategyWSO2
A good internal and external API management strategy and architecture is key to building ecosystem platforms that lead to successful API economies in the enterprise. This workshop will look at best practices in API management using the WSO2 API Manager and Integration Platform products, which are used to rapidly implement RESTful design, enforce governance policies, safely scale solutions, orchestrate complex interaction sequences, and re-use assets. The session will also look at reference architectures and architectural recommendations of building large scale API ecosystems.
Director - Solutions Architecture at WSO2, Mifan Careem presented this session at APIdays Sydney 2015.
A quick overview on REST : what it is and what it is not. REST has strict contraints and many internet Apis are not so REST. It’s also very popular today because RESTfull services can be consumed easily by any client or device. Soap is also still valid in a few circomstaces. It has never been so easy to create Rest-like services in .net since asp.net Web Api.

Less Is More: Utilizing Ballerina to Architect a Cloud Data PlatformWSO2
At its core, the challenge of managing Human Resources data is an integration challenge: estimates range from 2-3 HR systems in use at a typical SMB, up to a few dozen systems implemented amongst enterprise HR departments, and these systems seldom integrate seamlessly between themselves. Providing a multi-tenant, cloud-native solution to integrate these hundreds of HR-related systems, normalize their disparate data models and then render that consolidated information for stakeholder decision making has been a substantial undertaking, but one significantly eased by leveraging Ballerina. In this session, we’ll cover:
The overall software architecture for VHR’s Cloud Data Platform
Critical decision points leading to adoption of Ballerina for the CDP
Ballerina’s role in multiple evolutionary steps to the current architecture
Roadmap for the CDP architecture and plans for Ballerina
WSO2’s partnership in bringing continual success for the CD
The integration landscape is changing rapidly with the introduction of technologies like GraphQL, gRPC, stream processing, iPaaS, and platformless. However, not all existing applications and industries can keep up with these new technologies. Certain industries, like manufacturing, logistics, and finance, still rely on well-established EDI-based message formats. Some applications use XML or CSV with file-based communications, while others have strict on premises deployment requirements. This talk focuses on how Ballerina's built-in integration capabilities can bridge the gap between "old" and "new" technologies, modernizing enterprise applications without disrupting business operations.

Securing your Kubernetes cluster_ a step-by-step guide to success !KatiaHIMEUR1
Today, after several years of existence, an extremely active community and an ultra-dynamic ecosystem, Kubernetes has established itself as the de facto standard in container orchestration. Thanks to a wide range of managed services, it has never been so easy to set up a ready-to-use Kubernetes cluster.
However, this ease of use means that the subject of security in Kubernetes is often left for later, or even neglected. This exposes companies to significant risks.
In this talk, I'll show you step-by-step how to secure your Kubernetes cluster for greater peace of mind and reliability.
Elevating Tactical DDD Patterns Through Object CalisthenicsDorra BARTAGUIZ
After immersing yourself in the blue book and its red counterpart, attending DDD-focused conferences, and applying tactical patterns, you're left with a crucial question: How do I ensure my design is effective? Tactical patterns within Domain-Driven Design (DDD) serve as guiding principles for creating clear and manageable domain models. However, achieving success with these patterns requires additional guidance. Interestingly, we've observed that a set of constraints initially designed for training purposes remarkably aligns with effective pattern implementation, offering a more ‘mechanical’ approach. Let's explore together how Object Calisthenics can elevate the design of your tactical DDD patterns, offering concrete help for those venturing into DDD for the first time!
Threats to mobile devices are more prevalent and increasing in scope and complexity. Users of mobile devices desire to take full advantage of the features
available on those devices, but many of the features provide convenience and capability but sacrifice security. This best practices guide outlines steps the users can take to better protect personal devices and information.

2. What is REST?
● REpresentational State Transfer
● Lightweight, ClientServer architecture
● Interactions are based on the transfer of
resource state representations
● Systems exchange state representations and
perform application state transitions
● Mostly implemented using HTTP but can be
based on other protocols
3. Origin and Growth
● First introduced by Roy Fielding in his doctoral
dissertation
● Developed in parallel with HTTP/1.1
● WWW is the largest known implementation of a
RESTful architecture
● Widely used in modern days as an alternative to
technologies like CORBA and SOAP
4. REST By Example...
● Learning Management System for a school
● A number of fundamental concepts
● Student
● Course
● Teacher
● In a RESTful design these concepts are likely to
become the 'resources' managed by the LMS
8. Application State
● Applications have states
● Number of students in the system
● Number of associations between students and
courses
● Number of teachers
● Application state transitions may occur as a
result of a resource state transfer
● Application state can also be represented using
some data format or hyper text references
9. Representational State Transfer
● Clients and servers interact with each other by
exchanging
● Resource state representations
● Application state representations
● Other control information
11. Why HTTP?
● Rich vocabulary and powerful tools that are
ideal for representing resource states,
application states and control data
● Application state – Status code + Links
● Resource state – HTTP entity
● Control data – HTTP method
● CRUD operations map nicely into HTTP
methods
13. Advantages
● Simple and lightweight
● Easy to implement
● Very little processing at the application level
● Small amount of data to pass around
● Support any content type
● Leverage builtin application layer protocol
semantics without reinventing the wheel
14. Notable Deployments
● Amazon AWS (Over 90% of the clients are
using the RESTful API)
● Google Maps
● Yahoo!
● eBay
● Sastry Malladi on service orientation
http://www.youtube.com/watch?v=O9osZGXDok
15. WSO2 ESB
● A lightweight, highperformance ESB
● Feature rich and standards compliant
● SOAP and WS* standards
● REST support
● Variety of protocols and message formats
● User friendly and highly extensible
● 100% free and open source with commercial
support
16. Under the Hood
● WSO2 ESB is based on a number of well
known Apache projects
● Synapse http://synapse.apache.org
● Axis2 http://axis.apache.org/axis2/java/core
● Web Services http://ws.apache.org
● REST support of WSO2 ESB stems from the
REST support offered by Axis2
17. REST Support in Axis2
● Axis2 provides a REST binding for each
deployed web service
● This enables clients to invoke any Axis2 service
via REST calls
● GET /services/HelloService/sayHello
● GET /services/MathService/add?a=5&b=10
18. REST Support in WSO2 ESB
● WSO2 ESB can receive and mediate REST
calls just like any other request
● The same mediators that work with SOAP can
be used to manipulate REST invocations
● Log, Send, Filter, Switch, XSLT, DBLookup....
● Additional handles provided by the ESB in the
form of properties
● Easily switch between SOAP and REST
30. REST APIs
● An API is similar to a web application hosted on
the ESB
● Anchored at a specific URL path (context)
● /test
● /dictionary
● /foo/bar
● Can be bound to a specific host and a port
● Contains one or more resources
31. Resources
● A RESTful resource exposed over HTTP
● Similar to a proxy service but focuses on REST
● Can be associated with
● A set of HTTP methods
– GET only, GET and POST only, All HTTP methods
● A specific content type
– application/xml, application/json
● A particular class of clients (user agents)
32. Dispatching Requests to a Resource
● URL patterns
● RegEx match (/test/*)
● Extension match (*.jsp)
● Exact match (/test/index.jsp)
● URI templates
● /dictionary/{character}/{word}
● /accounts/{accountId}/{operation}
37. API Management Goals
● Service provider objectives
● Define APIs
● Define security requirements and SLAs
● Monitor API usage and SLAs
● Service consumer objectives
● Discover and browse APIs
● Sign up and obtain API keys
● Consume APIs using the obtained keys
● Monitor API usage and SLAs
40. Summary and Recap
● REST is a lightweight, clientserver architecture for building
distributed systems
● RESTful designs are concerned with resources, states and
transfer of representational state between systems
● WSO2 ESB provides excellent support for receiving, processing
and intermediating REST (HTTP) calls
● The new API concept is a powerful feature which allows
developers to define REST APIs in the ESB without writing any
additional code
● WSO2 platform is ideally suited for developing comprehensive and
flexible API management solutions based on open standards
43. WSO2 Engagement Model
