The presentation from our online webinar "Design patterns for microservice architecture".
Full video from webinar available here: https://www.youtube.com/watch?v=826aAmG06KM
If you’re a CTO or a Lead Developer and you’re planning to design service-oriented architecture, it’s definitely a webinar tailored to your needs. Adrian Zmenda, our Lead Dev, will explain:
- when microservice architecture is a safe bet and what are some good alternatives
- what are the pros and cons of the most popular design patterns (API Gateway, Backend for Frontend and more)
- how to ensure that the communication between services is done right and what to do in case of connection issues
- why we’ve decided to use a monorepo (monolithic repository)
- what we’ve learned from using the remote procedure call framework gRPC
- how to monitor the efficiency of individual services and whole SOA-based systems.
At the Devoxx 2015 conference in Belgium, Guillaume Laforge, Product Ninja & Advocate at Restlet, presented about the never-ending REST API design debate, covering many topics like HTTP status codes, Hypermedia APIs, pagination/searching/filtering, and more.
Les Hazlewood, Stormpath co-founder and CTO and the Apache Shiro PMC Chair demonstrates how to design a beautiful REST + JSON API. Includes the principles of RESTful design, how REST differs from XML, tips for increasing adoption of your API, and security concerns.

In 1997 publiceerde Harvard professor en zakenman Clayton Christensen het boek “The Innovator’s Dilemma: When New Technologies Cause Great Firms to Fail’. Hierin beschrijft hij het verschijnsel dat veel grote bedrijven falen doordat ze niet op tijd inspelen op nieuwe ontwikkelingen. Toen was dus al duidelijk dat de wereld dusdanig snel verandert dat gevestigde bedrijven het steeds vaker niet meer kunnen bijbenen. Inmiddels zijn we 17 jaar verder en zijn de problemen voor deze bedrijven er niet minder op geworden.
Er is duidelijk een transitie gaande in de manier waarop waarde wordt gecreëerd. Recentelijk kocht het 10 jaar jonge Facebook het slechts 5 jaar geleden opgerichte Whatsapp voor 19 miljard dollar. Whatsapp is een bedrijfje met 55 medewerkers en bedient daarmee 450 miljoen gebruikers. Het concurreert rechtstreeks met traditionele telecom-giganten als KPN. De marktkapitalisatie van KPN is omgerekend ruim 4 miljard dollar. KPN bedient met 30.000 werknemers slechts een fractie van het aantal gebruikers van Whatsapp. Door dit soort ontwikkelingen zullen veel traditionele banen bedrijven verdwijnen of transformeren. Zo verhuurt het in 2008 begonnen AirBNB per nacht ongeveer 200.000 kamers en heeft een omzet gelijk aan die van de Hilton hotelketen. Bij Airbnb werken 130 mensen. Bij Hilton 144.000.
Hele sectoren worden op hun kop gezet door nieuwe spelers, een nieuw soort spelers. Grote bedrijven realiseren zich meer dan ooit wel dat ze innovatiever en wendbaarder moeten worden, maar worstelen met hoe ze dit praktisch aan moeten pakken. Ondertussen duikt steeds meer concurrentie op uit de meest onverwachte hoeken. Het besef dat het rigoreus anders moet dringt toch nog veel te langzaam door in de board room. Tijd dus voor een call-to-action. Op welke manier moeten de bedrijven van vandaag zich gaan organiseren om de toekomst van morgen met vertrouwen tegemoet te kunnen? Hoe ziet waardecreatie er in de toekomst uit? Wat zijn de gevolgen voor de organisatie van werk, voor de organisatie van organisaties?
TeamPark book (english) part 1, vision and inspirationPatrick Savalle
In every company, it is possible to identify processes that do not thrive well in a bureaucratic structure. The localization of people, content, and expertise, the utilization of special talents and the maintenance of usable innovation: many things run more smoothly when use is made of an organization’s social dimension. Many tasks can be performed better by organizing employees not just in teams but also in communities and crowds. An organization that makes use of social media,
social networks, crowdsourcing, stigmergic collaboration and other “2.0” concepts has an advantage over its competitors. This type of organization is what we are calling the “Intelligent Organization.”
This book gives a vision of that new organization. The accompanying book is "TeamPark, platform and method".
TeamPark book (english) part 2, platform and methodPatrick Savalle
Worlds first complete method to transform the enterprise into a socially integrated enterprise. Use web 2.0 style tools and collaboration to deindustrialize knowledge work, removing most of the problems facing normal 'bureaucratically' structured organizations.
In ieder bedrijf zijn processen te identificeren die niet optimaal gedijen in een bureaucratische inrichting.
Het vinden van mensen en resources; het lokaliseren van expertise; het benutten van bijzondere talenten en gaande houden van bruikbare innovatie.
Veel zaken verlopen soepeler via de sociale netwerken van het bedrijf. Veel taken zijn beter uit te voeren door werknemers niet alleen te organiseren in teams maar ook in communities. Een organisatie die zich bedient van Wiki’s, forums, social networks, crowd-sourcing, vraag– en aanbodfaciliteiten en andere ‘2.0’ middelen heeft een voordeel boven zijn concurrenten.
Zo’n organisatie noemen we de ‘Intelligente Organisatie’
Build the socially integrated organization with the TeamPark-methodPatrick Savalle
In every organization processes can be identified that do not function optimal in the normal, so called bureaucratic or formal structure.
Finding people or expertise, sharing and leveraging implicit knowledge, exploiting the wisdom of the crowd, using the special talents of people, driving sustainable innovation.
Many processes run more efficient and are more effective using the social networks of the organisation. Many tasks can be accomplished better by organizing people in communities instead of teams. An organization that knows how to use communities, social networks, crowd-sourcing, broadcast communication, self-organization and other ‘2.0’ concepts has an advantage over competitors and offers an appealing working environment.
The Intelligent Organization knows, build it with TeamPark
TeamPark is een visie en methode om te komen tot de Intelligente Organisatie. Een organisatie waarin een social platform de functionele kant van de organisatie aanvult en versterkt.
Een slagvaardigere en efficiëntere organisatie door grotere flexibiliteit, effectievere communicatie en samenwerking.
Betere ontsluiting en benutting van mensen, middelen, kennis en expertise door zelforganiserende processen.
Tevreden werknemers die kunnen werken op hun manier, op hun tijden en hun locatie.
Een collectief bewustzijn met een scherpere perceptie van maatschappij, trends, klanten en medewerkers.

The optimization of hybrid solar PV panels and pumped hydro energy supply systems plays a pivotal role in utilizing natural resources effectively. This initiative not only benefits humanity but also fosters environmental sustainability. The study investigated the design optimization of these hybrid systems, focusing on understanding solar radiation patterns, identifying geographical influences on solar radiation, formulating a mathematical model for system optimization, and determining the optimal configuration of PV panels and pumped hydro storage. Through a comparative analysis approach and eight weeks of data collection, the study addressed key research questions related to solar radiation patterns and optimal system design. The findings highlighted regions with heightened solar radiation levels, showcasing substantial potential for power generation and emphasizing the system's efficiency. Optimizing system design significantly boosted power generation, promoted renewable energy utilization, and enhanced energy storage capacity. The study underscored the benefits of optimizing hybrid solar PV panels and pumped hydro energy supply systems for sustainable energy usage.

Harnessing WebAssembly for Real-time Stateless Streaming PipelinesChristina Lin
Traditionally, dealing with real-time data pipelines has involved significant overhead, even for straightforward tasks like data transformation or masking. However, in this talk, we’ll venture into the dynamic realm of WebAssembly (WASM) and discover how it can revolutionize the creation of stateless streaming pipelines within a Kafka (Redpanda) broker. These pipelines are adept at managing low-latency, high-data-volume scenarios.
Water billing management system project report.pdfKamal Acharya
Our project entitled “Water Billing Management System” aims is to generate Water bill with all the charges and penalty. Manual system that is employed is extremely laborious and quite inadequate. It only makes the process more difficult and hard.
The aim of our project is to develop a system that is meant to partially computerize the work performed in the Water Board like generating monthly Water bill, record of consuming unit of water, store record of the customer and previous unpaid record.
We used HTML/PHP as front end and MYSQL as back end for developing our project. HTML is primarily a visual design environment.

Final project report on grocery store management system..pdfKamal Acharya
In today’s fast-changing business environment, it’s extremely important to be able to respond to client needs in the most effective and timely manner. If your customers wish to see your business online and have instant access to your products or services.
Online Grocery Store is an e-commerce website, which retails various grocery products. This project allows viewing various products available enables registered users to purchase desired products instantly using Paytm, UPI payment processor (Instant Pay) and also can place order by using Cash on Delivery (Pay Later) option. This project provides an easy access to Administrators and Managers to view orders placed using Pay Later and Instant Pay options.
In order to develop an e-commerce website, a number of Technologies must be studied and understood. These include multi-tiered architecture, server and client-side scripting techniques, implementation technologies, programming language (such as PHP, HTML, CSS, JavaScript) and MySQL relational databases. This is a project with the objective to develop a basic website where a consumer is provided with a shopping cart website and also to know about the technologies used to develop such a website.
This document will discuss each of the underlying technologies to create and implement an e- commerce website.
Online aptitude test management system project report.pdfKamal Acharya
The purpose of on-line aptitude test system is to take online test in an efficient manner and no time wasting for checking the paper. The main objective of on-line aptitude test system is to efficiently evaluate the candidate thoroughly through a fully automated system that not only saves lot of time but also gives fast results. For students they give papers according to their convenience and time and there is no need of using extra thing like paper, pen etc. This can be used in educational institutions as well as in corporate world. Can be used anywhere any time as it is a web based application (user Location doesn’t matter). No restriction that examiner has to be present when the candidate takes the test.
Every time when lecturers/professors need to conduct examinations they have to sit down think about the questions and then create a whole new set of questions for each and every exam. In some cases the professor may want to give an open book online exam that is the student can take the exam any time anywhere, but the student might have to answer the questions in a limited time period. The professor may want to change the sequence of questions for every student. The problem that a student has is whenever a date for the exam is declared the student has to take it and there is no way he can take it at some other time. This project will create an interface for the examiner to create and store questions in a repository. It will also create an interface for the student to take examinations at his convenience and the questions and/or exams may be timed. Thereby creating an application which can be used by examiners and examinee’s simultaneously.
Examination System is very useful for Teachers/Professors. As in the teaching profession, you are responsible for writing question papers. In the conventional method, you write the question paper on paper, keep question papers separate from answers and all this information you have to keep in a locker to avoid unauthorized access. Using the Examination System you can create a question paper and everything will be written to a single exam file in encrypted format. You can set the General and Administrator password to avoid unauthorized access to your question paper. Every time you start the examination, the program shuffles all the questions and selects them randomly from the database, which reduces the chances of memorizing the questions.

INHERITANCE-PATTERN
REDUCES THE NUMBER OF ENDPOINTS.
• PUT THE POST, PUT AND PATCH METHODS IN SUBTYPES
• PUT THE DELETE AND GET METHODS IN THE SUPER TYPE.
• WILL ONLY WORK IF AL INSTANCES HAVE UNIQUE ID S ACROSS THE HIERARCHY.

1. VISUALIZE THE LOGICAL DATAMODEL
CREATE THE CUSTOMER FACING LOGICAL DATAMODEL. AVOID STRICT 3NF-NORMALIZATION, N:M
RELATIONSHIPS ARE ALLOWED. USE ASSOCIATION AND INHERITANCE. BE VERY STRICT WITH THE
MULTIPLICITIES ON BOTH ENDS OF THE ASSOCIATIONS. MODEL NOT ONLY PERSISTENT TYPES BUT ALL
TYPES INCLUDING VOLATILE TYPES SUCH AS CALCULATED RESULTS.
REST-API ENDPOINT DESIGN PATTERNS
Created by: patrick.savalle@nn-group.com
2. ASSIGN ENDPOINTS TO TYPES
EACH TYPE GETS ITS OWN SET OF APPROPRIATE HTTP-METHODS (POST, PUT, PATCH, DELETE, GET) AND PATHS.
ESSENTIALLY CONVERTING THE DATAMODEL INTO A CLASS-MODEL. USE THE GUIDELINES ON THE RIGHT TO
DETERMINE THE MOST NATURAL ENDPOINT PATHS.
GUIDELINE: REFLECT RELATIONSHIPS IN ENDPOINT PATHS
DEPENDING ON THE TYPE OF ASSOCIATION BETWEEN TYPES (AGGREGATION VS. COMPOSITION) PREPEND THE PATHS OF PARTS WITH THE
PATHS OF THEIR WHOLES DEPENDENT PARTS SHOULD GENERALLY BE ACCESSED THROUGH THE WHOLE.

3. MATCH THE ENDPOINTS TO PROCESS STEPS
DRAW BPMN2 DIAGRAMS FOR A REPRESENTATIVE SET OF SCENARIO S AND RUN THEM AGAINST THE API.
A GOOD API SHOULD HAVE ITS ENDPOINTS CORRESPOND TO INDIVIDUAL PROCESS STEPS, ALMOST ONE-
ON-ONE.
