Two hard weeks
Ouh, two hard weeks are gone. We had a lot of work and a lot of IT crowd to manage. Different problems and different new systems are up and running. We extend our SMS gateway with a GSM modem positioned in Germany. Now we could send the German Short Messages via a German cell phone. This reduces the cost for our customers.
We also had a night shift this week (till 2am). In this night shift we simulated the catastrophe scenario for our central application portal (loss of the hole datacenter at our site). It was interesting because we were able to come up and running within 2 until 3 hours (from scratch) in Germany.
I think with the analyse of this test we will be able to simplify some components for a shorter recover time. Some topics will be DRBD and glusterfs.
We also implemented (the programmers) a kind of “webservice”. A middle layer between our data and the software from an external software partner. We decided to secure this by using client authentication (RSA PKI certificates) and also ip address restrictions.
Well, I think to weeks to remember because a lot of new and reworked things are now up an running – but a lot of work is still on the stack…….
