The document discusses software architecture and design topics such as moving from n-tier to service-oriented architectures (SOA). It describes how mORMot implements an SOA using interface-based services with RESTful APIs. Services are defined through interfaces and implemented on the server, then published and accessed by clients. This allows for loosely coupled and platform-independent services that can be composed together. The document also covers logical vs physical views, service lifetimes, security, analytics, and callbacks over WebSockets.
EKON20 Conference, November 2016
Monolithic rich Windows applications are not enough for our customers. We are often requested to provide a web front-end, or a REST server to be consumed by mobile or thin clients. Integrating n-Tier architecture to an existing project is challenging. Some good practices, based on industry standards and proven design patterns (like uncoupling or SOLID) can be mind-breaker for RAD developers. In this session, we will define some architectural aspects of SOA, ORM and MVC/MVVM, and what our Open Source mORMot framework offers to ease this transition.
Some slides, as presented during EKON20 conferences, about the mORMot Open Source project, a Delphi/FPC professional framework featuring highly integrated SOA, MVC, ORM, SOLID over SQL and NoSQL databases.
SOLID principles should better be applied when designing business objects, as soon as maintainability and modularity are needed. They bring uncoupling, abstraction and clean design to Object Oriented Programming. Microservices could be seen as SOLID principles applied to the Service Oriented Architecture. In respect to a classical monolith server, thanks to uncoupling and better granularity, you may enhance deployment, ease cooperation between dev teams, introduce Domain Driven Design and/or Event Driven Design, scale horizontally and still incorporate existing code and services.
After a quick and practical review of SOLID principles, we will see how they may apply to SOA, and how Microservices could be defined using the Open Source mORMot framework interface-based services, on Windows or Linux.

After years working on Domain-Driven Design projects using Delphi for server-side processes, I eventually followed some kind of cut-back version of the DDD paradigms. Introducing Kingdom Driven Design (aka KDD) – since in biology “Kingdom” is the second highest taxonomic rank, just after “Domain”. We will present some principles to help writing not-database-centric code, without being bloated by all the DDD requirements.
Let your Kingdom come!
Ekon23 (2) Kingdom-Driven-Design applied to Social Media with mORMotArnaud Bouchez
To illustrate the “Kingdom Driven Design” session proposal, we will expose and comment upon the software core of a custom social media service. It will create a network of user-generated content, not only connected around people or topics, but unleashing some reference text material: literature, law, science, religion – you name it. We will discuss proper KDD architecture, data structures, and associated microservices, using mORMot’s ORM and SOA as toolbox. The code of this new social media system will be disclosed under a GPL agreement, and running on production for years to come. It should be able to scale from a few users to worldwide adoption.
The most powerful way of writing REST services is to define them via interfaces, then let the SOA/REST framework do all the routing, data marshalling and communication behind the scenes. One distinctive feature of mORMot is to define a method parameter as a notification interface, and let the server call back the client when needed, as with regular Delphi code. This session will present the benefit of defining REST services using interfaces, and how WebSockets can offer real-time notifications into your rich Delphi client applications.
Server side process does react to business events. User actions, timers, other services may trigger states of change, which should be tracked and propagated. A classical implementation is to define a shared database or centralized message queue, locally or in the cloud. When applied to Microservices, this monolithic approach will quickly appear as a limitation.
In this session, we will introduce how Microservices could have their own dedicated persistence layer (i.e. database), and how real-time callbacks could be used to leverage real-time propagation of events, without any centralized message queue. Both ORM and SOA features of the Open Source mORMot framework will illustrate how to write such stand-alone services.

Modularity and Domain Driven Design - A killer combination - T De Wolf & S va...mfrancis
Applying domain driven design in a modular fashion has implications on how your data is structured and retrieved. A modular domain consists out of multiple loosely coupled sub-domains, each having their own modular schema in the database. How can we migrate and evolve the database schema’s separately with each new sub-domain version? And how do we match this with reporting and cross-domain use cases, where aggregation of data from multiple sub-domains is essential?
A case study concerning an OSGi-based business platform for automotive services has driven us to solve these challenges without sacrificing the hard-worked-on modularity and loose coupling.
In this presentation you will learn how we used Modular Domain Driven Design with OSGi. 'Liquibase' is elevated to become a first class citizen in OSGi by extending multiple sub-domains with automatic database migration capabilities. On the other hand, 'Elasticsearch' is integrated in OSGi to become a separate search module coordinating cross-domain use cases.
This unique combination enabled us to satisfy two important customer requirements. Functionally, the software should not be limited by module boundaries to answer business questions. Non-functionally, a future-proof platform is required in which the impact of change is contained and encapsulated in loosely coupled modules.

Enterprise Application Integration TechnologiesPeter R. Egli
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.
Open API and API Management - Introduction and Comparison of Products: TIBCO ...Kai Wähner
In October 2014, I had a talk at Jazoon in Zurich, Switzerland: "A New Front for SOA: Open API and API Management as Game Changer"
Open API represent the leading edge of a new business model, providing innovative ways for companies to expand brand value and routes to market, and create new value chains for intellectual property. In the past, SOA strategies mostly targeted internal users. Open APIs target mostly external partners.
This session introduces the concepts of Open API, its challenges and opportunities. API Management will become important in many areas, no matter if business-to-business (B2B) or business-to-customer (B2C) communication. Several real world use cases will discuss how to gain leverage due to API Management. The end of the session shows and compares API management products from different vendors such as TIBCO API Exchange, IBM, Apigee, 3scale, WSO2, MuleSoft, Mashery, Layer 7, Vordel
IN THIS SUMMARY
In Helping, Edgar H. Schein draws not only on his career expertise but from personal life experiences to establish a “general theory of helping” that holds true no matter what the social dynamics of the client/ helper relationship. Helping is a fundamental part of life: parents help their children, coaches their players, nurses their patients, managers their subordinates, yet despite its constant presence in daily life, the dynamics of giving and receiving help are poorly understood. When someone asks for help, they are temporarily lowering their own status and transferring status and power to the helper, creating an imbalanced relationship. Building a helping relationship means that the first client/helper interactions must be carefully managed by the helper toward building the client’s status up from their lower position and identifying which helping role to take vis-à-vis the client.

As a follow-up of the previous session about TFB, we will discuss what kind of tuning was made to the mORMot library, and its associated TFB sample implementation, to reach the top scores in charts. How can a pure Pascal project reach 7 millions of HTTP requests per seconds? How to scale and measure on high-end hardware? Are ORM frameworks damned to slow down everything? How to circumvent the lack of “async” programming at language level? How realistic is such a benchmark?
The TFB challenge is a performance comparison of many web app platforms, exercising JSON, database, ORM, HTML templates, all over HTTP. It compares the best frameworks written in C++, Rust, Go, JS, Java, C#… and now Pascal – thanks to mORMot. In this session, we will look and compare the source code of some frameworks samples, to distinguish their typical philosophy. We will see how modern Object Pascal is still relevant, and propose some ideas for the future of the language.
The OpenSource mORMot framework has a strong set of cryptography features. It offers symmetric cryptography with hashing and encryption, together with asymmetric cryptography via private/public key pairs. Its optimized pascal and assembly engines can be embedded into your executable, but you could also call an external OpenSSL library if needed. This session will present mormot.crypt.* units, and apply them to some use cases, from low-level algorithms to high-level JWT or file encryption and signing.
During the continuous mORMot refactoring, some core part of the framework was rewritten. In this session, we propose a journey to a refactoring of a single loop. It will take us from a naïve but working approach, to a 10 times faster Pascal rewrite, and then introduce how SSE2 and AVX2 assembly could boost the process even further – to reach more than 30 times improvement! No previous knowledge of assembly is needed: we will try to introduce how modern CPUs work, and will have some fun with algorithms and SIMD parallelism.
The OpenSource mORMot is a RESTful ORM / MVC / SOA framework for Delphi and FreePascal. Some of its codebase is now about 10 years old, and it was time to clean and evolve. This year 2020 triggered a deep refactoring of the whole source code, with a full rewrite of some core components (JSON, RTTI). This session will present the version 2 of mORMot it its current state, the principles behind this refactoring, and how you may find useful gems for your own Delphi applications.
High Performance Object Pascal Code on Servers (at EKON 22)Arnaud Bouchez
This EKON 22 conference is about high performance on servers, written in the object pascal (Delphi / FPC) language. Profiling should be the first step to avoid premature optimization, which is the root of all evil (Knuth). But when some bottlenecks are identified, we introduce some simple architecture patterns (like caching or microservices), data structures and algorithms to make process actually faster, with minimal refactoring. It was a fun session about how to write faster code, ending up by looking at the Delphi CPU view – even if you don’t know assembly.
This EKON 22 conference was not about the code formatting - where we put the “begin” keyword is mostly a matter of taste and convention. But it shows how the object pascal strong typing system, and its language expressiveness may help writing clean(er) code. Abstract SOLID principles could help define the class and services hierarchy. After years of server-side coding, we propose some practical guidelines for cleaner object pascal programming, to reduce technical debt, and allow cross-platform/cross-compiler support.

First Steps with Globus Compute Multi-User EndpointsGlobus
In this presentation we will share our experiences around getting started with the Globus Compute multi-user endpoint. Working with the Pharmacology group at the University of Auckland, we have previously written an application using Globus Compute that can offload computationally expensive steps in the researcher's workflows, which they wish to manage from their familiar Windows environments, onto the NeSI (New Zealand eScience Infrastructure) cluster. Some of the challenges we have encountered were that each researcher had to set up and manage their own single-user globus compute endpoint and that the workloads had varying resource requirements (CPUs, memory and wall time) between different runs. We hope that the multi-user endpoint will help to address these challenges and share an update on our progress here.

6. Multi-tier architecture
Often referred to as n-tier architecture
Client–server architecture in which:
Presentation
Application processing
Data management
are logically separated processes
Most widespread use of multi-tier architecture
is the 3-tier architecture
From n-Tier to SOA
11. Logical and Physical Views
Most of the time, n-Tier is intended
to be a physical (hardware) view
e.g. separation between the database server
and the application server
placing any tier on a separate machine
to facilitate ease of maintenance
From n-Tier to SOA
12. Logical and Physical Views
In SOA, we deal with logical layout
Separation of layers through logic interfaces
Underlying hardware implementation may,
but will usually not, match the logical layout

19. Service-Oriented Architecture
(SOA)
Definition:
Is a flexible set of design principles
used during the phases of
systems development and integration
Goal:
Package functionality as a suite of
inter-operable services
that can be used within multiple, separate systems
from several business domains
From n-Tier to SOA
20. Service-Oriented Architecture
(SOA)
The SOA implementations rely
on a mesh of uncoupled software services
Software Service:
A consumer asks a producer
to act in order to produce a result
Invocation is free from previous invocation
(stateless), to minimize resource consumption
From n-Tier to SOA
21. Service-Oriented Architecture
(SOA)
The SOA implementations rely
on a mesh of uncoupled software services
Those Services comprise
unassociated, loosely coupled
units of functionality
(each service implements one action)
that have no direct call to each other
(via protocols, catalogs over a bus)
From n-Tier to SOA
22. Service-Oriented Architecture

23. Service-Oriented Architecture
(SOA)
The SOA implementations rely
on a mesh of uncoupled software services
Service composition
Logical multi-tier orchestration (transactional)
A higher level service invokes several services
Works as a self-contained, stateless service
Lower-level services can still be stateless
E.g. application services over business services

Micro Services
SOLID principles meet SOA
Favor stateless calls
Enhance scaling abilities
Expects services discovery
From n-Tier to SOA
26. Service-Oriented Architecture
(SOA)
SOA is mainly about decoupling
It enables implementation independence
in a variety of ways
Platform
Location
Availability
Versions
From n-Tier to SOA
27. Service-Oriented Architecture
(SOA)
From n-Tier to SOA
Dependency Desired decoupling Decoupling technique
Platform
Hardware, Framework or Operating
System should not constrain choices
of the Services consumers
Standard protocols, mainly Web
services (e.g. SOAP or RESTful/JSON)
Location
Consumers may not be impacted by
service hosting changes
Routing and proxies will maintain
Services access
Availability
Maintenance tasks shall be
transparent
Remote access allows centralized
support on Server side
Versions
New services shall be introduced
without requiring upgrades of clients
Contract marshaling can be
implemented on the Server side
28. Service-Oriented Architecture
(SOA)
SOA will help contain the business logic
on the Server side, therefore :
Favor logical Multi-tier architecture
Uses less bandwidth than a fat client
From fat client to rich client
Leverage resources (DB, cache)
Easier to upgrade
Cheaper / Safer for the customer (backup, cloud)
From n-Tier to SOA
29. Service-Oriented Architecture
(SOA)
SOA expects a top/down mind :
Don’t start from the DB, but end-user app
Define services, not data structures
Ability to uncouple things
Identify bounded contexts and needed information
Modelize your business in reusable services
Focus on your domain to build tools and maximize ROI
Cross-cutting features may be delegated
Emailing, CRM, billing, reporting, UI…
From n-Tier to SOA

32. mORMot’s SOA
Services can be implemented as:
Method-based resource-focused services
Interface-based services
RESTful architecture
Over several protocols, e.g. HTTP/1.1
JSON and UTF-8 based
KISS / CoC design
From n-Tier to SOA
33. mORMot’s SOA
Method-based services
… have already been explained in REST context
Give full access to the request
Manual marshalling, e.g. for parameters
on the server side (error prone)
on the client side (dedicated code to write)
Still too close to the metal
From n-Tier to SOA
34. mORMot’s SOA
Interface-based services
Follow Delphi native abstraction of interface
Safe thanks to strong naming and typing
Parameters are marshaled via method signature
Optional dual-way callbacks (WebSockets)
Client-side wrapper is generated at runtime
Features RESTful JSON, so AJAX ready
Tied to mORMot’s RESTful and security model
Easily integrated with stubbing/mocking features
From n-Tier to SOA
35. mORMot’s SOA
Interface-based services
Abstraction allows loosely coupled relationship
Design by contract
Factory driven
on server side
on client side
Auto-marshalling to JSON
Tied to framework’s security and light sessions
Instance life-time, and execution threading
From n-Tier to SOA
36. mORMot’s SOA
Interface-based services steps:
Define a contract
Implement the contract on server side
Host and publish the service
Access the service from client side
From n-Tier to SOA
37. mORMot’s SOA
Define a contract
type
ICalculator = interface(IInvokable)
['{9A60C8ED-CEB2-4E09-87D4-4A16F496E5FE}']
/// add two signed 32 bit integers
function Add(n1,n2: integer): integer;
end;
ICalculator interface defines the contract
Add() method defines the operation
Handle any kind of parameters
Including classes, variants, dynamic arrays or records
From n-Tier to SOA
38. mORMot’s SOA
Implement the contract on server side
type
TServiceCalculator = class(TInterfacedObject, ICalculator)
public
function Add(n1,n2: integer): integer;
end;
function TServiceCalculator.Add(n1, n2: integer): integer;
begin
result := n1+n2;
end;
… and that’s all !
From n-Tier to SOA
39. mORMot’s SOA
Host and publish the service
Server.ServiceRegister(
TServiceCalculator,[TypeInfo(ICalculator)],sicShared);
will register the TServiceCalculator class
to implement the ICalculator service
with a single shared instance life time
to any TSQLRestServer instance
From n-Tier to SOA
40. mORMot’s SOA
Host and publish the service
Server.ServiceDefine(
TServiceCalculator,[ICalculator],sicShared);
will register the TServiceCalculator class
to any TSQLRestServer instance
to implement the ICalculator service
with a single shared instance life time
From n-Tier to SOA
41. mORMot’s SOA
Host and publish the service – instance life time
From n-Tier to SOA
Lifetime Use case
sicSingle An asynchronous process (may be resource consuming)
sicShared Either a very simple process, or requiring some global data
sicClientDriven
The best candidate to implement a Business Logic workflow
and light transactional process (Unit-Of-Work pattern)
sicPerSession To maintain some data specific to the client application
sicPerUser Access to some data specific to one user
sicPerGroup
Access to some data shared by a user category
(e.g. administrators, or guests)
sicPerThread Thread-oriented process (e.g. for proper library initialization)
42. mORMot’s SOA
Access the service from client side
Client.ServiceDefine([ICalculator],sicShared);
var I: ICalculator;
begin
if Client.Services['Calculator'].Get(I) then
result := I.Add(10,20);
end;
Register to any kind of TSQLRestClient
Execution will take place on the server side
A “fake” class implementing ICalculator will be created
Data is transmitted by representation as JSON (array of) values
Any server-side exception will be transmitted to the client
From n-Tier to SOA
43. mORMot’s SOA
Interface-based services routing
Classes available by default:
you can define your own class
From n-Tier to SOA
TSQLRestRoutingREST TSQLRestRoutingJSON_RPC
Description RESTful mode JSON-RPC mode
Default Yes No
URI scheme
/Model/Interface.Method[/ClientDrivenID]
or /Model/Interface/Method[/ClientDrivenID]
+ optional URI-encoded params
/Model/Interface
Body content
JSON array (or object) of parameters
or void if parameters were encoded at URI
{"method":"MethodName",
"params":[...]
[,"id":ClientDrivenID]}
Security
RESTful authentication for each method
or for the whole service (interface)
RESTful authentication for the
whole service (interface)
44. mORMot’s SOA
Interface-based services execution modes
Per-method threading behavior
From n-Tier to SOA
TServiceMethodOptions Description
none (default)
All methods are re-entrant and shall be coded to be thread-safe
(best scaling performance, but may be error prone)
optExecLockedPerInterface Each interface will be protected/locked by its own mutex
optExecInMainThread
optFreeInMainThread
Methods will be executed in the process main thread
Interface will be released in the process main thread
optExecInPerInterfaceThread
optFreeInPerInterfaceThread
Each interface will execute its methods in its own thread
Each interface will be freed in its own thread
45. mORMot’s SOA
Interface-based services security
Based on framework’s RESTful authentication
Expects a user to be authenticated
and an in-memory session to be initiated
Once authenticated, every service is by default allowed
You can restrain execution per group,
using a fluent interface, e.g.
Server.ServiceDefine(
TServiceCalculator,ICalculator],sicShared).
DenyAll.
AllowAllByName(['Supervisor']);
From n-Tier to SOA
46. mORMot’s SOA
Interface-based services analytics
Every REST call logged in a (SQLite3) DB
Interface & Method name
Input & Output parameters (or exceptions)
User session, Time elapsed
With no performance penalty (using batch)
Disabled by default, enabled in one call
Allows real-time or after-time detailed analytics
As powerful SQL statements
Remotely accessible from DDD ToolsAdmin

55. mORMot’s SOA
Interface-based services callbacks
Beware of the “race conditions” or “dead locks”
Use critical sections to protect your shared data
in a multi-threaded server to avoid race conditions
If your callback triggers another method
which shares the same critical section
in another thread, you may have a dead lock
Gather all non-blocking callback process
in a background thread using
TSQLRest.AsynchRedirect
