Week 9 - Coronavirus

Image
Link to Week 8 Monday - May 4 I was still battling server issues. The load on the server was not just going down. Even starting 20 EC2 instances did not help. It was making it worse - and slowing the site and app further. Monday morning I started with Angamardhana + SMM on the terrace. While doing the yoga+kriya I get an insight - I am not kidding - perhaps the memcache is failing on heavy load. After standup I test my theory and it turned out to be true. When Memcache fails, all calls start hitting the database - and hence the load. Increasing more EC2 instances, was making more memcache failures, and more database load. By noon the issue is resolved. App and site are back to their super fast mode. I am jumping with joy here - and no one to tell. I go to tell San, but she is in the middle of a long meeting with the Sales heads - they are strategising the Life time ERP free the competitor is touting.  ADDA’s P&C Team ( People & Culture - we do not call ours as Human Resources )
