Cloud Business Case: A step-by-step guide

This document aims to guide you through the process of creating a cloud business case calculation with the Business Case Builder module in Txture.

The main use-case of the Business Case Builder is in the preparation phase of bids and offers when the following criteria are met:

  • Only technical/infrastructure data from cloud estates, on-premises, database inventories etc. is known
  • Quick cost estimations for cloud target architectures are required
  • Several scenarios should be compared and presented

Step 1: Data input​

The starting point for each business case calculation is the data input via the Data Source Management in the Txture Admin section. The process is the same as in the Transformation Cockpit.

  • Identify available data sources: frequently mainly data dumps from cloud estates, IT infrastructure or database inventories are available in this project phase
  • Create data sources for each of these resources
  • Create asset importers for the different asset-types (virtual servers, etc.)

Consider current limitations

  • Computations are limited to one region per proposal
  • Pricing estimations do not include network and runtime usage data

After finishing the data import, navigate to the section Business Case Builder in the menu bar.

Step 2: Add new Business Case​

Based on the data input in the previous step, Txture now calculates the business case. To create potential cloud target scenarios you need to follow these 4 steps:

  1. Click Add new
  2. Fill in required fields
  3. Set Target Architecture Preferences
  4. Specify a scope

Repeat these 4 steps above to generate alternative cases for different cloud providers, locations, technologies etc.

Target Architecture Preference Settings

Have a look at the detailed description of Target Architecture Preferences for more information.

Step 3: Business Case Comparison​

The Business Case Builder shows the As-Is and all generated cloud target architectures next to each other to facilitate easy comparison. Choose between the different comparison modes:

  • Products/Sizing: Enables quick comparison of used technologies per business case, showing cost and sizing grouped by asset type.

  • Cost: Lists the monthly prices of the calculated business cases side by side to identify the most attractive proposal in terms of cost. It also displays the currently selected pricing options in a combined price comparison chart, showing how much each scenario would cost per month.

  • Migration Stats: Gives a quick overview which component-wise migration strategies are used (e.g. Replace, Replatform, etc.), to roughly indicate complexity and effort of a migration.

By clicking on View Details, you can open the detail view for the selected business case, which will provide you with further insight into the proposed target architecture.

In addition to the Overview, you can access the As-Is data, the detailed Price & Bill of Materials and more information about the proposed Products in the detailed view of the business cases.
