Scalability and High AvailabilityLaajuus (5 cr)

Objective

Purpose of the course
You learn matters and techniques affecting scalability and availability of systems and software and the principles of their design.

Competences
EU-KW: EUR-ACE Knowledge and understanding
EU-EC: EUR-ACE Engineering practice

Learning objective of the course
You understand the concepts of scalability and high availability and how to affect them. You know various mechanisms affecting scalability and high availability as well as their weaknesses and benefits. You are able to design scalable systems where redundancy, load balancing and high availability have been taken into account.

Content

Scalability of applications, asynchronous and synchronous applications and their scalability.
Load balancing: physical and software-based. Load balancing on various layers of the OSI model: Layer 4 and Layer 7. Load balancing algorithms. Latency. Redundancy. Planned and unplanned breaks.
Scalability in cloud.
Terms related to the techniques, e.g. failover, uptime, downtime, master, slave/backup.

Assessment criteria, satisfactory (1)

Sufficient 1:The student masters sufficiently the theory of scalability and high availability and is able to recognize some of the techniques affecting them. The student is able to design and implement partly scalable systems where high availability has been considered based on the system or software requirement specification.
