Every time when I'm asked by "non tech person", what I am doing for work ... I default to "IT Engineer". But even within our field I'm experiencing misconceptions. Many tie #devops with #cloud. Or maybe it's just me thinking otherwise 😅
And to be fair many of our job activities are a bit here a bit there.

I'm still surprised to see in many places issues with handling SSL certificates. eg. internal/external self-signed. Many Java based apps require to have them imported into truststore. Then expiry date comes and broken connection is (hopefully) starting monitoring alarm.

Wrote small article as I was in such cases :)

Certificate expiry

In world where everything is connected and exposed to internet, interacting with self-signed certificates can be unique experience.

Sysops note:
Learning happens in the gaps between design and cock-ups.
Root disk filled, Postgres did the right thing and refused to start, backups proved their worth, DB moved onto its own volume, system calmer than before.
Architecture improves fastest when reality gets a vote.

W ciągu ostatnich 3 miesięcy zdałem #AWS-owe trio certyfikatów Cloud Associate, czyli #Developer, #SysOps oraz #SolutionArchitect. Zacząłem od SAA. Najtrudniejszym był #SAA, jego pytania były najdłuższe i najbardziej wymagały zastanowienia, natomiast najprostszym był #DVA - ten jest na kompletnie niższym poziomie zaawansowania (nie licząc pewnych wyjątków). #SOA to w zasadzie trochę taki SAA, ale z krótszymi pytaniami i bardziej skupiający się na korzystaniu z AWS-a niż na migracjach.
