This document discusses Service Oriented Architecture (SOA). It defines key SOA concepts like services, service orientation, and fundamental SOA constructs. It also covers SOA principles, tools, benefits, and the differences between web services and SOA services. Specifically, it notes that SOA aims to reduce costs and complexity by dividing projects into independent and reusable components/services that can be composed to address business needs.
A service-oriented architecture (SOA) is an architectural pattern in computer software design in which application components provide services to other components via a communications protocol, typically over a network. The principles of service-orientation are independent of any vendor, product or technology.

Formalization of SOA concepts with mathematical foundation IJECEIAES
With the development of the IT industry, agility and dynamicity are the two expected characteristics for any business enterprise. Service Oriented Architecture (SOA) an emerging and a promising advent aiming at address the current trends/needs of enterprise business applications. The current work aims at giving an overview of the conceptual model of SOA based on set theory approach. Also, it posits mathematical definitions for logical, environment and application service definition with the help of general systems theory and mathematical foundation. The mathematical model, definition and functionality of services enhance SOA principles which can be used efficiently in integrating heterogeneous components.
Contemporary research challenges and applications of service oriented archite...Dr. Shahanawaj Ahamad
Service Oriented Architecture (SOA) is distributed architectural framework that provides service-based
solutions for improving the effectiveness of enterprise’s IT infrastructure. In this framework, technical and
business processes are implemented as services. A service is an independent software application that has been
designed to perform a specific function with emphasis on loose coupling between interacting services and their
components. SOA permits developers to utilize many of the resources from existing services to form the
distributed applications. This study has investigated to highlight the emerging issues of SOA such as service
structures advancement, requirements of evolution for current age applications like mobile-cloud, medical and
mechanism for interoperable operations. The paper also uncovers the practical application domains of SOA. It
has identified research attentions in these domains with detection of issues to carry further research to
overcome constraints in current scenarios.

0x01 - Newton's Third Law: Static vs. Dynamic AbusersOWASP Beja
f you offer a service on the web, odds are that someone will abuse it. Be it an API, a SaaS, a PaaS, or even a static website, someone somewhere will try to figure out a way to use it to their own needs. In this talk we'll compare measures that are effective against static attackers and how to battle a dynamic attacker who adapts to your counter-measures.

4. Architecture Definition in IEEE
1471
Architecture :
The fundamental organization of a system
embodied in it’s components, their relationships
to each other, and to the environment, and the
principles guiding it’s design and evolution
Architect :
The person, team, or organization responsible for
designing systems architecture
5. Software Architecture
What is Software Architecture?
The software architecture of a program or computing
system is a depiction of the system that aids in the
understanding of how the system behave
Serves as blueprint for both the system and the project
developing
The primary carrier of system qualities
An artifact for early analysis
Set of structures needed to reason about the system
Documentation of a system
7. SOA
An architecture style that model system’s information
into services
Old division between business and IT
Basic understanding of SOA development as a
application that describe web services
Logical evolution of the software’s modeling
Not a new concept
8. SOA Definition from various
viewpoints
SOA is a journey that promises to :
reduce the lifetime cost of the
application portfolio
Maximize RIO in both application
and technology resource
Reduce lead times in delivering
solutions to business
9. SOA Definition from various
viewpoints
SOA is a set of services that can be:
Exposed to their customers ,partners
and other part of organization
Business capabilities , function , and
business logic can be combined
Application serve the business
11. SOA Definition from various
viewpoints
SOA is a means to create dynamic ,
highly configurable and collaborative
application built for change
SOA reduce IT complexity and
rigidity
SOA becomes the solution to stop
the gradual entropy
SOA reduces lead times and costs
12. SOA Definition from various
viewpoints
SOA is the architectural solution for
integrating diverse systems by
providing an architectural style that
promotes loose coupling and reuse
13. SOA Definition from various
viewpoints
SOA is a programming model or paradigm
where web services and contracts becomes
a dominate design for interoperability
Use WSDL or equivalent specification
for describing the service
14. SOA Definition
Delivering on the promises of SOA :
Improved business agility
Maximized ROI
Reduce IT complexity and rigidity
Reduce costs
Reduce lead times
Reduce risk
New opportunities to deliver value
Increased participation in value networks
Incremental implementation
17. What Are The Fundamental
Constructs Of SOA?
The most basic construct or building block of SOA is a
service
Service consumer, service provider, service description,
service broker, and a registry are all part of the DNA of
SOA
A service in SOA is the logical, self-contained business
function
18. What Are The Fundamental
Constructs Of SOA?
Services in SOA have the following attributes:
Stateless
Discoverable
Self-describing
Compostable
Loose coupling
Governed by policy
Independent location, language, and protocol
19. What Are The Fundamental
Constructs Of SOA?
Services in a service-oriented architecture typically
have the following characteristics:
Coarse-grained
Asynchronous
22. SOA Terms
Service-Orientation
Services
Service-Models
Service Composition
Service Inventory
Service-Oriented Analysis
Service Candidate
Service-Oriented Design
Service Contract
Service-Related Granularity
23. Service-Orientation
design paradigm intended for the creation of solution logic
units
As a design paradigm for distributed computing, service-orientation
can be compared to object-orientation
25. Services
A unit of solution logic to which service-orientation
has been applied to a meaningful extent.
As a physically independent software program with
specific design characteristics
Each service is assigned its own distinct functional
context and is comprised of a set of capabilities related
to this context
Considered a container of capabilities associated with
a common purpose
27. Services
Three common service implementation is :
Services as Components
Services as Web Services
Services as REST Services
28. Services as Component
A software program designed to be part of a
distributed system
It provides a technical interface comparable to a
traditional API
have typically relied on platform-specific development
and runtime technologies
29. Services as Web Services
Is a body of solution logic that provides a physically
decoupled technical contract consisting of a WSDL
definition and one or more XML Schema definitions
and also possible WS-Policy expressions
Web service contract exposes public capabilities as
operations
Service-orientation can be applied to the design of
Web services
31. Services as REST Services
Are designed in compliance with the REST
architectural style
Focuses on the resource as the key element of
abstraction
Can be further shaped by the application of service-orientation
principles
32. Services Models
Is a classification used to indicate that a service
belongs to one of several predefined types
Three service models are common to most enterprise
environments and therefore common to most SOA
projects:
Task Service
Entity Service
Utility Service
Play an important role during service-oriented
analysis and service oriented design phases
33. Services Composition
Is an aggregate of services collectively composed to
automate a particular task or business process
To qualify as a composition, at least two participation
services plus one composition initiator need to be
present
Can be classified into primitive and complex variations
35. Services Inventory
Is an independently standardized and governed
collection of complementary services within a
boundary that represents an enterprise or a
meaningful segment of an enterprise
When an organization has multiple service
inventories, this term is further qualified as domain
service inventory
36. Services-Oriented Analysis
Represents one of the early stages in an SOA initiative
and the first phase in the service delivery cycle
The service-oriented analysis process is commonly
carried out iteratively, once for each business process
A key success factor of the service-oriented analysis
process is the hands-on collaboration of both business
analysts and technology architects
38. Services Candidate
Is used to help distinguish a conceptualized service
from an actual implemented service
39. Services-Oriented Design
Represents a service delivery lifecycle stage dedicated
to producing service contracts in support of the well-established
“contract-first” approach to software
development
The typical starting point for the service-oriented
design process is a service candidate
There is a different service-oriented design process for
each of the three common service models
40. Services Contract
Is comprised of one or more published documents that
express meta information about a service
The fundamental part of a service contract consists of
the documents that express its technical interface
When services are implemented as Web services, the
most common service description documents are the
WSDL definition, XML schema definition, and WS-Policy
definition
44. Services-Related Granularity
there are different granularity levels as follows:
Service Granularity
Capability Granularity
Constraint Granularity
Data Granularity
46. What Is The Difference Between a
Web Service and an SOA Service?
47. Benefits Of SOA
New products or processes simply execute
Flexible systems are not obstacle to changing and
rapid evolution of processes
48. Benefits Of SOA
Solving complex integration problem of large systems
49. Benefits Of SOA
Divided of project into smaller components that can
be done independent is simply
Control of progress in each subproject is calculated
50. Benefits Of SOA
Integration and connecting to other systems is
dominant approach
51. Benefits Of SOA
Systems easily meet the requirements of users
The problem of data transfer between systems is
solved with integration
Complexity of systems hidden from users
52. Benefits Of SOA
Enterprise architects believe that the SOA can help the
business to response faster and more cost-effective to
market conditions changing
This style of architecture use reusability in macro level
instead micro level
53. Orchestration and Choreography
Without process engine
Sequence of transaction
messages register and
controlled by players
Have a process engine
Call set of services to complete
process
Maybe call external services
Sample of this system is
BPMS
54. Principles of SOA
Loose coupling
Service contract to communications agreement
Encapsulation of internal implementation
Reusability
Composability
Statelessness Services
Discoverability Services
Autonomy Services
