# Title
|
|
|
|
Using Linux Application-Containers for a Distributed University Computer Lab Terminal-Service Focused on Efficiency, Scalability and Security
|
|
|
|
# Abstract

|
# Introduction
|
|
|
|
## Goals
|
|
|
|
* Providing Remote Terminal Services For Running Linux Applications
|
|
* Terminal Services run in application containers
|
|
* Application Containers can be built from arbitrary sources
|
|
|
|
* Terminal User's are isolated from each other on the Operating System level
|
|
|
|
Isolated Resources:
|
|
* Root Privileges
|
|
* CPU
|
|
* RAM
|
|
* Network Stack
|
|
* Disk
|
|
|
|
* User's have full control over their own processes
|
|
* Long-running applications (Terminal Services) in the ephemeral application-container ecosystem
|
|
* Migrating vs. Re-Starting Terminal Services
|
|
* Integrated User Management Platform
|
|
* Cluster Container Manager
|
|
* Separable Storage For Containers
|
|
* Operating System
|
|
|
|
### Optionals
|
|
|
|
* Infrastructure Management
|
|
* Software Defined Networking Management
|
|
|

# Solution Design
|
|
|
|
## Issues
|
|
* Only one main Gitlab Server
|
|
* Doesn't scale
|
|
* Only one terminal server
|
|
* not all servers are used by this terminal server
|
|
* all users work in the same environment
|
|
* users share resources like CPU, Memory, partially temporary disk space
|
|
* Terminal Server OS has every courses applications installed
|
|
* Terminal Server is not easily relocatable due to Local-FS usage
|
|
* Classical Disk Quota is buggy with SimFS used for the OpenVZ guests
|
|
* DLM/CMAN Quorum is not reliable --> Clustered Volume Management is not reliable
|
