I've also been told, time and again, in no uncertain terms, to "buy as much as possible". We've reached the logical conclusion of SaaS-everything: every company just cobbles together expensive, overcomplicated computers from other expensive, overcomplicated computer providers, resulting in expensive, bloated systems that barely work.
Recall that the poster said this was for a small startup. If you're Google, by all means, use Google logging tools. If you aren't, then solve the problem you have, not the problem your résumé needs.

And the poster above answered that question
mkdir -p /tmp/ssh_output
while read ssh_host; do
ssh "$ssh_host" grep 'keyword' /var/my/app.log > "/tmp/ssh_output/${ssh_host}.log" &
done < ssh_hosts.txt
wait
cat /tmp/ssh_output/*.log
rm -rf /tmp/ssh_output
More power to you for using sed awk and grep, they're powerful tools and every computer person should know how to use them. But if you're hung up on only using sed awk and grep for emotional reasons, that's self-limiting. We have better tools today, and you don't get hero points for using shittier tools when there are better ones available to you.
