Assignment 5 1 Availability and Redundancy Security Reflection - Oliver-Mustoe/Oliver-Mustoe-Tech-Journal GitHub Wiki

My overall experience with the availability and redundancy topics we have covered so far in class has been enlightening. This class feels like a natural evolution from previous sysadmin and security classes, where we started with a relatively simple flat network into a more complex network with redundancy. In this new network I have learned a lot about certain tech I never used in class or in general. VRRP was something that I initially thought was going to be harder to setup but in the end wasn't too bad. Using techniques such as using arp and ip checking to see which VRRP host is the master is also beneficial as virtual ips do make troubleshooting a bit harder. I would definitely recommend to setup VRRP before other networking is done though as you don't have to later go back and deal with changing configurations. Load balancing is another tech I didn't have much knowledge in. I remember using haproxy in a previous class but we dived much deeper into it in this class. I had to learn about the different modes and how to use checks to ensure haproxy was only using the appropriate server if it was still up. Up until this reflection I have learned a lot in this class about availability/redundancy and I hope to learn more about it and even automate some parts of it...
