Networking is at the heart of MAAS, and getting it right is essential for smooth operations. Here are some key steps to take:
Connect MAAS networks: First things first – connect those MAAS networks. You’ll need to connect MAAS nodes and controllers; without this, you’re going nowhere fast. You may also find it useful to bone up on MAAS networking essentials before you start this step.
Enable DHCP: Next up, DHCP. You must set up DHCP correctly if you want MAAS to discover your machines. Without this, your machines are just shouting into the void, with no place to get an IP address and nowhere to get a Network Boot Program (NBP). Hint: DHCP problems cause more MAAS issues than just about anything else; if you have any gray areas of understanding, it wouldn’t hurt to check out our DHCP primer, appropriately titled, “It is always DHCP” (when it’s not DNS, that is).
Manage availability zones: And don’t forget availability zones. MAAS lets you allocate machines to different zones to ensure fault-tolerance. If you’re running critical applications, like music streaming or disaster recovery, AZs can save you a lot of time and headaches.
