DevOps Automation

Let’s take a close look at the business objectives of a large global bank to understand DevOps –

  • CEO of the company wishes to bring down IT RUN cost down by at least 20%
  • CTO of the bank wants to improve the resilience of the IT applications
  • COO wants to re-design the organization with lean and Agile processes
  • As a company they want to roll-out new products and services at a rapid rate

These objectives need to translate into objectives for the IT organization inside the bank, so that a fast, collaborative and cross functional execution enables the business leaders to full fill the business goals.

Hence, what do these business objectives mean to the IT organization??

Let us have a look,

CEO of the company wishes to bring down the IT RUN cost down by at least
20%. For IT translates into,

  • Eliminate the technical waste that eats the cost
  • Improved Automation across the SDLC

CTO of the bank wants to improve the resilience of the IT applications.

For IT translates into,

  • Better Tools and monitoring of production code
  • On demand spin up and spin down environment capacity

CEO / COO wants to re-design the organization with lean and Agile processes.
For IT translates into,

  • Agile methodologies and processes
  • Collaborative workforce for quicker turn around
  • Cross-functional team to take up additional responsibilities

DevOps adoption journey in the global bank will allow the IT team to full fill the above goals, and provide tangible business benefits such as, the bank would be able reduce the customer enrollment for a product from weeks to 2 days.

Key characteristics of DevOps:

  • Quick Development and Better Quality – rolling out feature every week
  • Faster and successful deployment to Production – At least 3X faster deployment cycle

During the DevOps training, you will learn how to achieve business goals/objective by implementing IT imperatives.
