Cost Saving Worksheet for a Typical Application

This document discusses the cost of developing and operating an application with and without Trillo Workbench. It considers a typical medium-sized application as an example. The cost is the same for the analysis, requirement and functional design phases in both cases.

The tables below are summaries for development and . The sections following provide detailed worksheets of how costs are calculated.

Development and Deployment Phase Costs

PhaseWithout (Trillo Workbench)With (Trillo Workbench)Savings
Development (until integration testing)USD 1.2MUSD 280KUSD 920K
Production readiness and deploymentUSD 240KUSD 40KUSD 200K

Production Phase Cost (recurring monthly cost)

PhaseWithout (Trillo Workbench)With (Trillo Workbench)Savings
Recurring monthly cost of operation and maintenanceUSD 12.5K

USD 9.5K

(includes cost of Trillo Workbench License)

USD 3K
  • The recurring cost does not include the cost of enhancements. The cost would remain proportionately lower with Trillo Workbench.
  • Since Trillo Workbench is a platform for building the server side of an application, the cost of development of UI is not considered. In our experience, the cost of UI is 40-50% when using Trillo Workbench. It is due to the uniformity of APIs and on-time availability of servers.

Costing Without Trillo Workbench

The following sheet shows the total cost of ownership (TOC) of an application without Trillo Workbench listed by 3 phases – A) Development, B) Production Readiness & Deployment, C) Recurring Monthly Cost in Production

Development

Total Cost: 900K – 1.2M

Cost Basis: A typical medium size enterprise class application requires a team of 15 people for 6-8 months. The team composition is shown in the following table. The blended cost of 10K per person per month is assumed.

RoleNumber of PeopleResponsibilities
Cloud Architect1Design a scalable deployment architecture for services.
Cloud Engineer1Write DevOps scripts.
Platform Engineers4Build core services such as – data, storage, OAuth2 integration, audit service, cloud service integration, etc.
Application Architect1Design data model and business processes.
Application Engineers4Write application code (due to evolving platform core services they work at 50% efficiency)
QA42 for testing core services, 2 for application code

Production Readiness & Deployment

The process production readiness process is iterative using these typical steps:

  1. Stress test.
  2. Security, compliance and governance audit.
  3. Fix issues identified.
  4. Repeat 1-3.

Total Cost: 160K – 240K

Cost Basis: 8 people, 2-3 months, blended cost of 10K per person per month.

RoleNumber of PeopleResponsibilities
Security Architect1Conduct security audits, identify issues and prioritize them.
Cloud Architect1Redesign cloud configuration based on security review.
Cloud Engineer1Change DevOps scripts.
Platform Engineers2Fix performance, scalability, reliability, and security issues.
Application Engineers2Redesign code that has performance, scalability, reliability and security issues.
QA1Test changes, rerun test suite.

Recurring Monthly Cost in Production

Costing With Trillo Workbench

The following sheet shows the total cost of ownership (TOC) of an application with Trillo Workbench listed by 3 phases – A) Development, B) Production Readiness & Deployment, C) Recurring Monthly Cost in Production

Development

Total Cost: 210K-280K

Cost Basis: A typical medium size enterprise class application requires a team of 7 people for a period of 3-4 months. The team composition is shown in the following table. The blended cost of 10K per person per month is assumed.

RoleNumber of PeopleResponsibilities
Application Architect1Design data model and business processes.
Application Engineers4Write application code.
QA2For application code

Production Readiness & Deployment

Production readiness is an iterative process as depicted in the following steps (typical):

  1. Stress test.
  2. Security, compliance and governance audit.
  3. Fix issues identified.
  4. 1-3 will go much faster with the Trillo Workbench.

Total Cost: 20-40K

Cost Basis: 4 people, 0.5-1 month, blended cost of 10K per person per month.

RoleNumber of PeopleResponsibilities
Security Architect1Conduct security audits, identify issues and prioritize them.
Cloud Architect1
