More work.. and more kubernetes

October 3, 2019

Having resolved to see through to the end, I volunteered and took up more responsibility at work. With a huge influx of new comers to the project I took up on getting them acclimated to the new workplace – across India. My team now boasted of 40+ members from a count of less than 20 a year back. I also expanded on the Kubernetes implementation – including logging and monitoring to the cluster along with additional services. Thanks to my boss for guiding me on the right path on all of this. The demo environment was finally moved to the…

Dropthought, Meet Kubernetes

August 21, 2019

After rigorous planning, testing and creating a ton of new files and architecture, I migrated the Test and Stage environments of my application to Kubernetes – EKS (Elastic Kubernetes Service) in particular. I used Jenkins to build the application, stored the images in Elastic Container Registry (ECR) and deploy the containers in EKS clusters. All the time spent for meticulous customization ensured that there was a lot of room for expansion and could accommodate more services as the application grew.

A trip to California

June 15, 2019

Hello California! I go on a short business trip to US with the goal to plan, design and migrate the existing Dropthought v2 application to Kubernetes! Time to get my hands dirty and boy it was a blast! I also started on a new diet to shed some weight around the mid section. Never realized it would actually pay off.

Under Heavy load

June 21, 2018 12:00 AM

I get a request to architect the application Infrastructure to handle 1000+ concurrent connections per second. Ridiculous? Yes. But since the one ordering is my boss, I set out to do exactly that and pulled it out as well. Thanks to ELB, ASG, custom AMI and a couple of sleepless nights. Oh and I also had to design redis and the web server to handle the load. Had a ton of fun experimenting stuff. Not to mention creating a test machine to simulate that damn load!

Cost Optimization

April 19, 2018

Having observed a huge drain in the monthly expenses for the cloud account used by Dropthought, I charted out avenues where resources were left unused and forgotten. Having realized this exercise would take up time, I estimated this to be done in 2 months only to realize it would go on for 3 more than that.. At the end of it though, I had managed to bring down the monthly expense by 54% from the previous year.

Firewall Upgrade at TelBru

November 22, 2015

TelBru’s firewalls were planned to be replaced as part of the technical refresh activity that was on going. Volunteered to be part of the team that planned the firewall migration. Successfully migrated TelBru’s existing firewall to Fortinet’s 1200B (Hardware and Software). Picked up on how to configure Force 10 MXL Network switches to selectively route network traffic from a set of blade servers through a particular VLAN to comply with the new Firewall policies. What I won’t say is that I was sought out much after I left TelBru to do the same thing thrice for other network switches as…

Transition to a new role and a new Employer

Time for a change..

October 30, 2014

After 4 years, I decided to quit and look for a change. I just didn’t realize what the future had in store for me. Nor did I realize that I am in for a very difficult time in job search. The punch line? Being jobless and having several close misses does help overcome the fear of job hunting. In hindsight, resolving to leave this comfort zone was one of the best decisions of my life!
