Q

The Need for Integration

A

Integration assists in formation of Zero Latency organization, when all functions within the organization work with the same up-to-date information, latency between applications is eliminated/reduced.

Q

Fundamental Challenges of Integration

A

Distributed - in the worst case every applications runs on a completely separate environment. Database storage is not shared among applications.

Q

Fundamental Challenges of Integration

A

Networks are slow - sending data across a network is multiple orders of magnitude slower than making a local method call.

Q

Fundamental Challenges of Integration

A

Any two applications are different - integration solutions need to transmit information between systems that use different programming languages, operating platforms, and data formats.

Asynchronous messaging is fundamentally a practical reaction to the problems of distributed systems. Sending a message doesn't require both systems to be up and ready at the same time.

Messaging

The reason a messaging system needed to move messages from one computer to another is that computers and the networks that connect them are inherently unreliable.

Messaging

Four Methods Used in Application Integration

1. Send and Forget 2. Store and Forward

Software systems designed to support interoperable machine-to-machine interaction over network.

Web Services

XML

Extensible Markup Language

SOAP

Simple Object Access Protocol

REST

Representational State Transfer

This is where web services are often implemented. Services are loosely coupled and can be combined to create new applications.

Service-Oriented-Architecture (SOA)

Components of Web Services

1. Service Provider 2. Service Requestor/Consumer 3. Service Registry 4. Service Description

The entity that hosts and provides the web service.

Service Provider

The entity that accesses and uses the web service.

Service Requestor/Consumer

A directory that maintains information about available web services.

Service Registry

Metadata that describes the capabilities and interface of a web service.

Service Description

Types of Web Services

1. SOAP Web Services 2. RESTful Web Services

Acts as a bridge between different applications, enabling communication and integration.

Middleware

Middleware in Web Services

1. Message Transformation 2. Security 3. Transaction Management 4. Service Orchestration

Converting data formats from different systems.

Message Transformation

Enforcing authentication, authorization, and encryption.

Security

Handling distributed transactions across multiple services.

Transaction Management

Combining multiple services to execute complex business processes.

Service Orchestration

Allows different systems to communicate regardless of their underlying technologies.

Interoperability

Can handle a large number of concurrent requests and adapt to changing workloads.

Scalability

Supports various communication protocols and data formats.

Flexibility

Provides mechanisms for secure communication and data exchange.

Security

Facilitates seamless integration of heterogeneous systems.

Integration

Involves designing and implementing software that communicates over a network.

Network Programming

Endpoints for communication between two nodes on a network.

Sockets

In network programming, _____ programming is used to establish connections, send and receive data, and manage network communication.

Socket

Types of Socket

1. TCP Sockets 2. UDP Sockets 3. Raw Sockets

Provides reliable, connection oriented communication with error handling and flow control.

TCP Socket

Offers fast, connectionless communication without reliability guarantees.

UDP Socket

Allows direct access to network protocols for advanced network operations.

Raw Sockets

The foundational protocol suite for internet communication, including protocols like TCP, IP, HTTP, FTP, and SMTP.

TCP/IP

Protocols for web communication, with HTTPS adding encryption for secure data transmission.

HTTP and HTTPS

Protocol for email transmission

SMTP

Protocol for file transfer

FTP

Protocol for domain name resolution

DNS

Libraries like socket.h for low-level socket programming.

C/C++

Modules like socket and http.server for network communication.

Python

Classes like Socket and ServerSocket for TCP/IP communication.

Java

APIs like XMLHttpRequest and fetch for client-side network requests.

JavaScript

3 Types of Network Security

1. Encryption 2. Authentication 3. Firewalls and Intrusion Detection Systems (IDS)

Using protocols like SSL/TLS to encrypt data during transmission.

Encryption

Verifying the identity of communicating parties.

Authentication

Protecting networks from unauthorized access and attacks.

Firewalls and Intrusion Detection Systems (IDS)
