Narrative: At cruise; we had ECAMs for the Captain's window heat and a pack regulator fault. I completed the ECAMs. About 5 minutes later; the Captain's ND; PFD and the upper ECAM switched back and forth between being blank and having a diagonal line; finally going totally blank. The 3 screens came back to life about five minutes later and worked well for the remainder of the flight. Simultaneously; we had a multitude of various ECAMs. The aircraft also started to shake considerably. I assigned the FO (First Officer) to fly and I [notified ATC]; initially asking for a diversion to [a nearby airport]. After realizing that [another nearby airport] was behind us and quite a bit closer; I changed my diversion choice. I worked through the ECAMs and required checklists. The FO and I worked very well together and I kept Dispatch; the flight attendants and the passengers informed as the workload decreased. One important note - my iPad froze while I was trying to access JeppPro to brief the approach. I had to shut it down and restart it. Prior to this; I've never had a problem with my iPad. The airframe vibration intensified on the approach. The approach and landing were normal; but we didn't have reversers. This was a surprise because it wasn't displayed as an ECAM and didn't show on the STATUS page. Later the flight attendants told us that there was a vibration in the rear of the aircraft and the tail was swaying side to side. This swaying was indicative of a dual yaw damper failure. This was never made aware to us because it also wasn't an ECAM and didn't appear on the STATUS page.


Second narrative: ANTI ICE L Window and Windshield ECAMs came on in flight; Captain verified his windshield and back window were very cold to touch (unlike the normal heated windows). He looked up info in the [Maintenance Log] and we checked the QRH which related info we already knew 'left windshield heat failed.' A few moments later another ECAM relating to the left pack appeared. Captain noted the left-most fuel pump light also flicker on and off without indication of an ECAM. When the Captain was preparing to send the [Maintenance Report] codes for each of the ECAMs; his PFD; MFD and top ECAM flickered to red lines on and off and went blank. I think the Captain said 'Let's think about diverting; I don't like this' I completely concurred. Seconds later; multiple ECAM cautions began to appear with a 'ding' and yellow caution occurring almost every second; 10-15 times (?). The Captain called ATC and asked for a vector for ZZZ1 which appeared ahead of us (closest large airport; ~150 miles) on our map displays. ATC gave us a lower [altitude] (280?) and a slight turn. Moments later the Captain looked at the closest airports page and noted ZZZ was behind us but only 80 NM away - we changed our intended diversion airport to ZZZ; got another vector and continued descent. Captain gave me the radios; while he worked through the ECAM msgs/checklists. I left the autoflight system on in the ~180 deg turn to ZZZ.The system failures continued to chime and we felt a significant vibration/shaking on the flight deck (FAs later confirmed it was worse in the back). The failed systems that I recall at that point were those mentioned above plus Blue Hydraulic; Avionics cooling; a fuel pump; a pack. I kept taking deep breaths doing my own check for the smell of smoke; expecting it any moment with my O2 mask close by. We executed an ILS/Visual approach with normal speeds and flap settings; without the use of spoilers (the vibration/shaking worsened as we slowed). Landing/touchdown was normal; but neither thrust reversers developed any reverse thrust worked despite levers being in full reverse (there was no ECAM indication that stated they wouldn't be available). I let the aircraft slow mostly on its own until applying light braking. Ground fire support noted no external damage or fire so we taxied to gate.


Synopsis: A320 flight crew reported diverting to an alternate airport after experiencing multiple system failures in cruise flight.
