Challenges● Developer Onboarding was slow (~2 days)

● Manual Deployment

● Lack of Infrastructure Alignment

● CI/CD Environment was a SPOF

● Underutilized Infrastructure

Solution● Developers were productive in just ~2 hrs

● Fully Automated Deployment with Rollback

● Environment Consistency & Standardization

● Scalable CI/CD Infrastructure

● Infrastructure Efficiency

ING Delivers Value to Customers Faster with 1,500 deployments a week with Docker

Challenges● Slower deployment frequency

● Poor quality software

● Ever increasing CAPEX & OPEX costs

● Standardization across large groups of people, processes

and technology

Solution● Continuous Innovation

● Empower Engineers for Better Quality Software

● Increased Productivity and Speed

● Lower Costs

● Standardization and Scale

ROI ModelInfrastructure Efficiency:● €1k per month per server reduction opportunity● A 30% reduction is common from dev/test consolidation alone

Savings: 6 servers @ €1k/month = €6k/month = €72k/year

A corporate web site with development, test,

and production environments running on a

total of 20 servers

ROI ModelReduced Virtualization Overhead:● €340 per month per server reduction opportunity ● A 50% reduction in overall VM use

Savings: 10 servers @ €340/month = €3.4k/month = €40.8k/year
