Course at a Glance

Motivation and Scope

What is Middleware?

Say anything you think has something to do with middleware

Architecture
Tehnology
Tools
Concept or style
Methodology
...
No worries, there is no bad answer!

Motivation in Brief

Systems rely on complex infrastructures

A lot of data and many processes, internal and external
As people communicate, underlying systems must too
But:

variety of data formants, technologies, protocols
variety of architectures, client-server, peer-to-peer, ...

Rapid changes in applications' functionalities

modular development
reuse of application logic
low costs – do it now and quickly!

Good performance

frequent changes in applications' loads, peek hours
scalability – effective load balancing
low costs – cheaper to outsource?

Scope

Architectural and conceptual basis

What is architecture – enterprise, processes, data, software
Service concepts, integration patterns, middleware

Backend technologies

Communication protocols – HTTP, TLS, HTTP/2
Application backend and requests handling
Advances of REST, MOM

Performance and Scalability

Performance tuning
Load balancers

Requirements and Organization

Prerequisites

Object-oriented programming

Principles

class, object, inheritance, encapsulation, ...

basis for service concepts

JavaScript

All code examples will be in JavaScript
All lab work will be in JavaScript

Web Architecture

Basics of REST, HTTP, URI/URL

Other

Networking
Basics of OS

Organization of Labs

Individual work (no teams!)
Labs every second week
Number of labs: 6

Introduction - FIT Workspaces, setup
REST – Basics, development of a REST service
Security, TLS
Messaging systems
Load balancers, nginx

Methodology for Lab Work

No app development, not directly related assignments

assignment every second week
be prepared for the lab!
work alone, ask others for advices
Results:

5 completed tasks
you will submit results to gitlbab@FIT

Assessment

Labs

Every task gives you the maximum of 6 points = 30 points in total
Activity in labs gives you the maximum of 10 points
Total maximum points = 40, to pass: 20 points minimum

Final exam

Written exam: 3 exercises, 1 hour

each gives you a max. of 20 points, the total is 60 points
To pass, you need to have at least 50% from each exercise!

Final score:

100 points maximum
