Large Systems

  • Course name: Large Systems
  • Course number: xyz

Course Characteristics

Key concepts of the class

  • Virtualization and management of large systems
  • Communication, coordination and fault tolerance IT for infrastructure

What is the purpose of this course?

In large organizations complex architectures are built where products and protocols of multiple vendors have to inter-operate. The course focuses on understanding the challenges and building a scalable IT infrastructure that is flexible and efficient to manage. Topics covered are: Virtualization and Cloud Computing, Workstation and Server deployment, Data-centers and Infrastructure management methodologies.

Course objectives based on Bloom’s taxonomy

By the end of the course, the students should be able to remember the followings:

  • Install and configure large systems
  • Automate the installation and the deployment process in large systems
  • Usage of virtualized systems.
  • Manage scalable infrastructures
  • Fault tolerance and solutions in large systems

- What should a student be able to understand at the end of the course?

By the end of the course, the students should be able to understand the key components of large systems

  • Management and control of large systems
  • Different components and architectures of large systems
  • Role of virtualization and orchestration for managing large systems.

Typical questions for ongoing performance evaluation within this section

  1. What are containers? State at least three benefits of using them?
  2. Why memory reclamation approaches are needed for virtual machines?
  3. What are “cgroup” and “namespace” subsystems. How can we use the “cgroup” subsystem?
  4. Briefly explain about the “Ballooning” approach and its working to reclaim VM memory?
  5. What is a Unikernel? State at least two benefits and one drawback.

Typical questions for seminar classes (labs) within this section

  1. Validate that when a node goes down a new instance is launched. Show how the redistribution of the instances can happen when the broken node comes back alive?
  2. Deploy a simple application (e.g. a simple web page showing the hostname of the host node it is running upon) for each orchestrator and validate that its instances spreads around the container farm.
  3. What is the difference between simple load-balancing and HA load-balancing?
  4. Install at least 4 different types of guest systems or distributions on the physical host?
  5. Create a simple web page (preferably containing some pictures), construct an image with operating system you chose and deploy it via the unikernal.

Test questions for final assessment in this section

  1. State two benefits of immersion cooling over traditional air cooling in data centers?
  2. State one main difference of a container from a System Virtual machine?
  3. Briefly explain about Copy-on-write storage.
  4. What are the roles of “ISA” and “ABI” in operating systems?
  5. What is the biggest drawback of Google File system over CephFS?

Typical questions for ongoing performance evaluation within this section

  1. What is a schema-less data model?
  2. Why do we need NoSQL? What are its benefits over SQL in terms of ACID and BASE properties?
  3. Why is Anti-Entropy Protocol considered better than the Gossiping protocol for achieving consistency.

Typical questions for seminar classes (labs) within this section

  1. Create the testing environment to test VM monitoring through a running web page.
  2. Deploy zabbix server+agent (server is better to deploy on dedicated VM instance).
