- 16. Lessons Learned 16 All contents Copyright © 2013, MuleSoft Inc. “Eight months ago I started working at MuleSoft as an intern on the SaaS ISV partner team. When I evaluate my experience at MuleSoft, a cliche yet valid saying comes to mind: Everything happens for a reason.” “I would recommend MuleSoft to any intelligent, dedicated individual. We work really hard here, but all that time you are surrounded by awesome people that make working a fun and rewarding experience. If you want to work with people who want you to succeed, while challenging yourself everyday — come work at MuleSoft” - Source http://themuleternship.wordpress.com/ by Moira Chambers.

- Overview: Me / Myself / Adhish (its all about me) Problem Statement: Numbers (business bat) / Non Functional / Functional Challenges: Weight Loss / Developer Debt (Sonar / SQUEL) Before & After : Vendor Solutions Vs. Mule/Inhouse
- That’s me, yehey!!!
- Numbers: This project started in 2011 as a 5 year transformation.
- Current Volumes: This project was started in 2012 (planning in 2011) with 5 years to go live. Recover Time Objective: was twisted by business to Recover Time Operate. Future business: 2015 and beyond, as this was a 5 year plan, it started back in 2011. Storage: Played a critical aspect of the solution, we had to cut down on logging, implement other mechanism i.e. Splunk etc.
- Average CPU: was based line on the older application which was in production. Memory: same as the older application Use of GC: … DB Connections / MQ / Qpid etc.
- Talk about the Cash Business, file based, low value, large amount of data. Compound the problem with Country / Client / Time of transmission et`c.
- Talk about the complex of multiple files / clean up / data files / security / regulation(s) etc.
- Mule Shipped a trainer from Antwerp (Tom) to help us get the team in Hong Kong up and running, it was a 5 days intense course with hands on lab.
