SOFT8025 - Scalable Microservices

banner1
Title:Scalable Microservices
Long Title:Scalable Microservices
Module Code:SOFT8025
 
Credits: 5
NFQ Level:Advanced
Field of Study: Computer Software
Valid From: Semester 1 - 2017/18 ( September 2017 )
Module Delivered in 5 programme(s)
Module Coordinator: TIM HORGAN
Module Author: Donna OShea
Module Description: Over the past number of years, a new paradigm for software architecture has emerged, referred to as microservices. Microservices are singular in terms of their responsibility and can be independently scaled, tested and deployed. Services developed using this approach are built around business capabilities using best practices from domain-driven-design and are autonomous and isolated. In this module the student will learn a framework technology and using this framework will develop skills to build, automate, scale and manage a distributed system created from a number of collaborating components represented as microservices.
Learning Outcomes
On successful completion of this module the learner will be able to:
LO1 Apply a framework technology to develop a software application.
LO2 Design a distributed application composed of multiple collaborating services in the form of microservices.
LO3 Develop and deploy microservices in a distributed environment.
LO4 Execute microservices in a lightweight container.
LO5 Automate the deployment, scaling and management of containerised applications.
Pre-requisite learning
Module Recommendations
This is prior learning (or a practical skill) that is strongly recommended before enrolment in this module. You may enrol in this module if you have not acquired the recommended learning but you will have considerable difficulty in passing (i.e. achieving the learning outcomes of) the module. While the prior learning is expressed as named CIT module(s) it also allows for learning (in another module or modules) which is equivalent to the learning specified in the named module(s).
No recommendations listed
Incompatible Modules
These are modules which have learning outcomes that are too similar to the learning outcomes of this module. You may not earn additional credit for the same learning and therefore you may not enrol in this module if you have successfully completed any modules in the incompatible list.
No incompatible modules listed

Module Content & Assessment

Indicative Content
Core Framework Concepts
Overview of frameworks; Inversion of control; Dependency injection; Lightweight containers, such as Spring and Spring Boot; Object lifecycle management; Simplifying application configuration; Convention over configuration; Approaches to abstracting complexity, such as the template method pattern; Testability.
Microservice architecture principles
Distributed systems. Distributed sessions; Distributed transaction management; History of microservices - Service Oriented Architectures (SOA), Web Services, REST, Microservices. Monolithic service architecture versus micro-service architecture; Enterprise Service Bus (ESB); routing, choreography, transformation. Microservice architecture – package, deployment and management. Microservice characteristics. Microservice design.
Developing Micro-services
Spring Cloud – features, configuration. Building micro-services using RESTful API and Web Services. Configuring micro-services – YAML. Service Registration and discovery process: engines – Eureka, Consul, Zookeeper and others. Load balancing across services and Inter-process communication in the Cloud – Ribbon. Message bus - Asynchronous messaging. Circuit breakers and fault tolerance in microservices – Netflix Hystrix and Zuul. Unit testing and troubleshooting applications.
Lightweight containerisation
Lightweight containerisation – compare to traditional server virtualisation, approaches, benefits and implementations i.e. Docker. Running microservices in lightweight containers. Automating deployment, scaling and management of containerised applications – Kubernetes, Docker Swarm, Nomad, Kontena etc. Client side load balancing.
