### Load Balancer Funktionalitaet
Der Load Balancer wird gestartet. Er prueft ob in der SQLite-DB bereits Daten ueber Instanzen liegen.
Check out [Database columns](../../database/database_description.md)
Pro Eintrag (Zeile) werden A, B, C geholt und ein Instanz - Objekt mit den entsprechenden Daten erzeugt. Die Load - Balancer Klasse kommuniziert ueber die Klasse DBInterface mit der Datenbank. Die Klasse DBInterface implementiert die Funktionalitaeten, die notwendig sind, um mit der Datenbank zu kommunizieren.

Von Ziel aus anfangen zu planen
HPC Aufgabe, mit SSH aufschalten, Programm starten, C++
Idee: Falls kein Task verfuegbar, dann HPC Aufgabe, ansonsten Tasks
CPUh zu Waerme 1 CPUh == 4kW Waerme
CPU Zeit muss nicht genau gemessen werden, sondern nur Gesamtlaufzeit des Programms
Demod ein Mal aufrufen um Daten fuer Zeitraum zu generieren
Daten in sqlight DB schreiben
Project Outline (max 1 Din A4 Seite) auf Moodle hochladen, verwendete Progsprachen, Aufgaben pro Teammember
Aaron: Demod, Load Balancer, Definieren, was Load Balancer als Rueckgabewert haben will, ssh session von allen Heatern uebergeben an, Session in Objekt speichern und an Davids Programm uebergeben, Rueckgabe wann wurde es ausgefuehrt, wie lange lief es, Ergebnis soll im Load balancer landen, Verteilung der Aufgabe in Prozent auf die Instanzen an Davids Middleware schicken.
Python Funktion, Load Balancer soll selbstheilend sein, wenn Heater aussteigt
ssh -> Paramiko, pip install paramiko
Array mit Objekten, ein Objekt enthaelt ssh session und Prozentzahl, wie viel Bedarf, Feld fuer Ergebnis, in das Funktion von David Ergebnis schreibt, Statuswert ob Heater erreichbar war oder nicht
David: HPC Aufgabe, dominik.giel dgiel auf GitHub hinzufuegen.

Datenbank? Dateien?
sqlight, sehr einfache DB, Daten werden dort rein geschrieben
David: Graphana baut Dashboards aus Datenbank, sql abfragen bauen (naechstes Mal fragen ob graphana oder React? Schoenheit?)
UI holt sich Daten
Load Balancer kommuniziert mit den Heater Instanzen und Heat requirement system und schreibt die Daten in sqlight db.
An welchen Tagen wurde wie viel gearbeitet: Histogram
Hitzebedarf ueber Zeit: Zeitgraph x Zeit y Hitzebedarf
Auf naechsten Dienstag:
Theresa:
kleines GUI Mockup vorbereiten
David:
Load Balancer, demod einlesen, kann erst ab 03.05 wg. Bachelorarbeit
Instanz zum laufen bringen
Aaron:
Anderes Projekt mit einfachen Tasks researchen, Iterationsschritt immer gleich lang, Zuverlaessigkeit der Tasks gegeben? CPU soll was zu tun haben
