CORBA is a distributed object technology standard that allows objects to communicate with one another regardless of programming language or location. It uses an Object Request Broker (ORB) to handle requests and responses between clients and servers. CORBA defines an Interface Definition Language (IDL) to specify object interfaces independently of programming languages. The IDL compiler then generates stub and skeleton code to enable communication. CORBA provides interoperability, location transparency, and other services to facilitate distributed object communication.
Servlet is java class which extends the functionality of web server by dynamically generating web pages.

Overview of Microsoft .NET Platform and Components. .NET is Microsoft's managed code platform. .NET comes with a wealth of libraries for communication (WCF), graphical user interfaces (WPF, WinForms), database access (ADO.NET, SQL) etc.
Component Object Model (COM, DCOM, COM+)Peter R. Egli
Â
Overview of Microsoft COM / DCOM technology.
DCOM is Microsoft's component technology and can be roughly compared to CORBA technology. DCOM is however tightly bound to the Windows operating system (Win32 API). Windows Runtime is a newer Microsoft technology that borrows much of the concepts of COM/DCOM.
LPWAN Technologies for Internet of Things (IoT) and M2M ScenariosPeter R. Egli
Â
Rapid technological advances in the past made possible the miniaturization of network devices to meet the cost and power consumption requirements in IoT and M2M scenarios. What is missing in this picture is a radio technology with both long range capability and a very low cost footprint. Existing radio technologies such as 3G/4G or Short Range Radio do not aptly meet the requirements of IoT scenarios because they are either too expensive or are not able to provide the required range. Other wireless technologies are geared towards high bandwidth which is in most cases not a requirement for IoT.
Emerging LPWAN technologies such as ETSI LTN or LoRAWAN are poised for filling the gap by providing long range (up to 40km) and low power connectivity. These technologies allow low cost radio devices and operation thus enabling scaling up IoT applications.
Networking is a term that subsumes various technologies and protocols for transferring data from one place to another by means of a transmission network.
While every technology like TCP/IP, Ethernet, SDH, GSM, VSAT etc. has its own zoo of terms and acronyms, there are more fundamental concepts and terms common to the different technologies and protocols.
The goal of this document is to explain the gist of the these more common networking terms and concepts. These explanations complement typical glossaries with illustrations.
Transaction Processing Monitors represent an early type of middleware that is still widely used for performing distributed transactions involving multiple databases.
Usually TPMs employ the two phase commit protocol that ensures ACID properties (Atomicity, Consistency, Isolation, Durability) as in relational databases.
Business Process Model and Notation (BPMN)Peter R. Egli
Â
Overview of Business Process Model and Notation (BPMN) language for modeling business processes.
When implementing business processes, there is usually a large gap between the business semantics (process, activity, participant, orchestration, choreography, data items etc.) and the technical implementation languages (REST, WSDL, transport protocol, message bus etc.). BPMN has the goal of bridging this gap by providing a standard notation for describing business processes plus a standard mapping of this notation into an executable description language like WSBPEL. The BPMN 2.0 standard even allows executing BPMN business models directly without the need of a translation.
The core notation elements of BPMN are flow objects to model activities and events, data objects to model pieces of information, connecting objects to model information and control flow, and swimlanes to model process participants. Four different diagram types allow the modeling of processes, process choreographies, collaboration between participants and conversations.
Overview of Cloud Computing, Infrastructure as a Service, Platform as a Service, Software as a Service.
Cloud computing means transferring ICT resources (servers, hosts, applications, databases, platforms etc.) to a cloud service provider (CSP) with the goal of reducing capital expenditures (CapEx).
Cloud computing differs from legacy hosting services in that CSPs offer standardized services on a massive scale which results in economy-of-scale effects thus further reducing operating expenses (OpEx).
Different cloud models such as public, private and hybrid clouds address different customer needs.
The 3 categories for the functional level of cloud services are IaaS (Infrastructure as a Service),
PaaS (Platform as a Service) and SaaS (Software as a Service). Countless models emerge almost daily such as MaaS (Management as a Service), BaaS (Backend as a Service) and NaaS (Network as a Service).
To accommodate increases in processing power, cloud services offer the possibility to scale-up or scale-out.
MQTT - MQ Telemetry Transport for Message QueueingPeter R. Egli
Â
Description of message queueing (MQ) protocol for the transport of telemetry data (MQTT - MQ Telemetry Transport).
MQTT is a protocol designed to fit the needs of Internet of Things scenarios. It is lightweight and efficient, but still affords all the features required for reliable messaging between wireless sensor / actor nodes and applications. MQTT decouples producer and consumer of data (sensors, actors and applications) through message brokers with publish / subscribe message queues called topics. MQTT supports different levels of quality of service thus providing the flexibility to adapt to the different needs of applications.
Further features like will and retain messages make MQTT well suited for sensor network scenarios as well as for lightweight enterprise messaging applications.
Open source implementations like Eclipse paho provide ample code for integrating MQTT in your own applications.
Enterprise Application Integration TechnologiesPeter R. Egli
Â
Overview of Enterprise Application Integration Technologies.
Enterprise Application Integration, or EAI in short, aims at integrating different applications into an IT application landscape. Traditionally, EAI was understood as using the same communication infrastructure by all applications without service-orientation in mind. This meant that the benefits of a shared infrastructure were limited while driving up costs through additional integration platforms.
Service Oriented Architectures (SOA) brought a new paradigm by decomposing applications into reusable and shareable services. Service orientation requires careful design of services. A hierarchic scheme of services may help to define a suitable service decomposition.
While SOA is technically based on big web service technologies, namely SOAP, WSDL and BPEL, WOA or Web Oriented Architecture stands for the lightweight service paradigm. WOA makes use of REST-based technologies like JSON and HTTP.
In many cases, an Enterprise Service Bus (ESB) is used as an infrastructure element to achieve the technical integration of the services. The ESB core functions like message routing, filtering and transformation provide the mediation services required to integrate heterogeneous application landscapes.
Overview of Microsoft .Net Remoting technologyPeter R. Egli
Â
Overview of Microsoft .Net Remoting technology for inter-object communication.
.Net remoting is a .Net-based distributed object technology for accessing
.Net objects that reside in a different application domain (different process
on the same machine or different process on another machine).
.Net shares concepts with DCOM (Distributed Component Object Model), but
simplifies the communication with regard to transport ports and programmatic
model.
Microsoft's newer WCF (Windows Communication Foundation) provides a unified communication and programming model thus replacing older technologies like .Net remoting and DCOM in many applications.
Overview of Android NDK (Native Development Toolkit).
Android application development is primarily done with the Android SDK.
Apps are written in Java thus benefitting from the high-level constructs
of the managed environment as well as the wealth of functionality provided
by the Android application platform.
However, sometimes it is necessary to implement certain functionality natively
in C++, e.g. when access to hardware is required or 3rd party stacks have to
be included that are only available as C++ code.
The NDK is a lightweight development toolkit for writing native applications
and libraries that can interwork with Java application code.
Overview of SCTP (Stream Control Transmission Protocol)Peter R. Egli
Â
Overview of SCTP (Stream Control Transmission Protocol), outlining the main features and capabilities of SCTP.
SCTP is a transport protocol that overcomes many of the shortcomings of TCP, namely head-of-line blocking and stream-oriented transmission.
SCTP supports multiple streams within a connection and preserves boundaries of application messages thus greatly simplifying communication.
Additionally, SCTP supports multi-homing which increases availability in applications with high reliability demands.
SCTP inherits much of the congestion, flow and error control mechanisms of TCP.
SCTP has its roots in telecom carrier networks for use in transitional voice over IP scenarios.
However, SCTP is generic so that it is applicable in many enterprise applications as well.

Overview of web services and web service architectures.
Web services have come of age and are the foundation of today's enterprise application architectures.
Service Oriented Architecture (SOA) break up traditional application silos into reusable services shared and used by different applications.
Web services group and encapsulate related functionality into reusable functional units.
Web service intermediaries complement the business functionality exposed by web services with
functions such as authentication, load balancing, logging and caching.
To control web service consumer and producer compatibility, web services should carry the version of the service in the interface.
Overview of Spanning Tree Protocol (STP & RSTP)Peter R. Egli
Â
Ethernet networks require a loop-free topology, otherwise more and more broadcastand unknown unicast frames would swamp the network (creation of frame duplicates resulting in a broadcast storm). Spanning Tree Protocol (IEEE 802.1D) and its faster successor RSTP (IEEE 802.1w) provide loop prevention in bridged networks by establising a loop-free tree of forwarding paths between any two bridges in a network with multiple physical paths. If a link fails, STP and RSTP automatically establishes a new loop-free topology. This presentation describes in detail how STP and RSTP work along with typical examples.
Overview of Microsoft Message Queueing (MSMQ) messaging technology.
MSMQ is Microsoft's message queueing technology that also integrates well into the newer Windows Communication Foundation framework.
MSMQ provides most of the features and functionality typical of message queueing systems.
Overview of JMS messaging API.
JMS (Java Messaging Service) is an API for asynchronous message based communication between Java based applications.
JMS implementations (instances that implement the JMS API) are called JMS providers.
JMS defines two messaging domains. Point-to-point queues are typically used between one or multiple message senders and a single message receiver.
Topics are multi-point queues where messages are distributed to multiple receivers. As such topics resemble a black board.
Like many other message oriented middleware technologies, JMS provides advanced functions like persistent message delivery mode or different message acknowledgment modes.
Additionally, messages can be sent and received in a transacted mode thus ensuring that either all or no messages are sent and received.
JMS integrates into EJB (Enterprise Java Beans) through message driven beans.
Overview of web services, SOAP, WSDL and UDDI.
A web service provides a defined set of functionality on a machine-processable interface.
The web service interface is described in a formal language like WSDL that allows creating code to access the service thus simplifying web service consumer (client) and provider (server) development.
In big web services, the interface is typically described in WSDL while the access to the service makes use of the SOAP message protocol.
SOAP has its roots in remote object access but is now a general message based and asynchronous transport mechanism.
SOAP is typically carried in HTTP (HyperText Transmission Protocol), but other message based protocols like SMTP (Email) or plain TCP could be used as well.
WSDL provides a formalized description of an interface that is coarsely separated in an abstract service interface definition containing operations and data types, a transport binding that describes how the web service is accessed and finally a description of the location (address) under which a web service is accessible.
UDDI (Universal Description and Discovery Protocol) was meant to become the standard protocol for some kind of a public yellow pages where publicly accessible web services would be listed. Lack of industry interest, however, prevented UDDI to gain widespread use.
Overview of REST web service concepts (Representational State Transfer).
REST is a radically different approach for web services compared to the combo SOAP/WSDL.
REST defines an architectural style for web applications and web services.
REST makes heavy use of the underlying HTTP protocol.
REST itself is not a protocol but defines architectural principles based on the concept of addressable resources and a uniform access to these resources based on the well-known HTTP-methods GET, POST, PUT and DELETE.
The state of a client (web service consumer) is controlled by the REST web service through connected links between resources (resource oriented architecture). The client state however is stored on the client itself thus greatly increasing scalability of REST-based architectures.
The REST paradigm has mostly superseded SOAP / WSDL type web services in many enterprise applications. This is largely owed to the fact that the underlying HTTP protocol is well understood and proved its scalability in the WWW.
Overview of message oriented middleware technology (MOM).
Message Oriented Middleware allows asynchronous operation between sender and receiver of information. This greatly reduces temporal coupling and allows building flexible and extensible application architectures. Message queues managed by message brokers are used as information exchanges between sender and receiver. The subscribe-publish pattern allows producers and consumers to share information through message brokers without any direct coupling between them. Various message oriented protocols like MSMQ, AMQP, XMPP and MQTT have emerged that serve the diverse needs of different environments.
Overview of Microsoft WCF communication technology (Windows Communication Foundation).
WCF is a unified communication framework for distributed .Net applications.
WCF defines a common programming model and unified API for clients and services to send messages between each other.
WCF is the current and future standard for distributed .Net applications.
One of WCFs core concept is ABC which stands for Address, Binding and Contract.
The address defines a service's location. The binding defines how the service can be accessed and the contract defines the service interface.
This common model allows a uniform programming model for distributed applications not only based on web services, but also on message based transports like MSMQ.

"Impact of front-end architecture on development cost", Viktor TurskyiFwdays
Â
I have heard many times that architecture is not important for the front-end. Also, many times I have seen how developers implement features on the front-end just following the standard rules for a framework and think that this is enough to successfully launch the project, and then the project fails. How to prevent this and what approach to choose? I have launched dozens of complex projects and during the talk we will analyze which approaches have worked for me and which have not.
