Cloud Proposal Score

Txture assigns an overall score to each generated proposal to indicate how well it performs. This score makes it easy to compare different proposals within a list of proposals.

The overall score is made up of multiple category scores, each representing a specific aspect of the proposal. Every category score is calculated from a set of sub-scores, each with its own weight.

  • Some weights are predefined.
  • Others are influenced by your configured Target Architecture Preferences (e.g., your cloud service provider preference or sensitivity towards cheaper prices).

Each category score is calculated as a weighted average of its sub-scores. The overall score is then calculated as a weighted average of the category scores.

As of now, Txture considers three categories for the overall ranking of a proposal

Score Interpretation​

Higher scores always indicate better performance - but the meaning of "better" depends on the context of each score. Here are some examples:

  • Vendor Lock-in: A higher score means lower risk of vendor lock-in, which is generally more desirable.

  • Sustainability: A higher score means the proposal is more sustainable, for example by reducing energy consumption or utilizing greener cloud regions.

  • Migration Effort: A higher score indicates lower overall effort required for migration, meaning the proposal is easier to implement.

This consistent scoring direction makes it easier to interpret and compare different proposals at a glance.

Cloud Benefit​

The Cloud Benefit score measures the overall advantages of the proposed solution in terms of maintainability, scalability, and vendor lock-in. This score provides a holistic view of the benefits derived from the selected cloud products. If the proposal includes multiple cloud services, the score represents an aggregated evaluation across all products used.

Maintainability​

Assesses how easy it is to operate and maintain the proposed solution. Cloud products that offer managed services generally score higher, as they reduce operational complexity compared to self-managed solutions like dedicated hosts or custom compute clusters.

Scaling Capability​

Evaluates the solution’s ability to scale infrastructure and resources in response to workload changes. Proposals that rely on services with automated, provider-managed scaling achieve higher scores, while those requiring manual scaling or complex configurations score lower.

Vendor Lock-In​

Measures the degree of flexibility in switching cloud vendors or technologies. A lower risk of vendor lock-in results in a higher score. Products that are standardized across providers or based on widely supported technologies are considered less restrictive.

Cloud Strategy​

The Cloud Strategy score measures how well the proposed cloud solution aligns with the configured preferences and strategic goals.

Cost Optimization​

Represents the projected cost of the proposal on the selected cloud provider, with lower costs contributing to higher scores.

Sustainability​

Evaluates the environmental impact of the proposal, including estimated carbon footprint and energy consumption. More sustainable solutions receive higher scores.

Landing Zone​

Assesses how well the proposed solution matches the preferred landing zone (e.g. public vs. private cloud environments).

Preferred Technology​

Measures alignment with the specified preferred technologies. Proposals using favorite technologies or services score higher.

Favorite Location​

Indicates how well the proposal meets location-related preferences for cloud deployment regions.

Favorite Provider​

Reflects the degree of alignment with the preferred cloud service providers defined in the target architecture preferences.

Certifications​

Scores how well the solution aligns with required or preferred certifications, such as ISO or industry-specific standards.

Cloud Approach​

The score is based solely on the weight of the cloud approach configured in the preferences. This way, the favored cloud approaches are reflected in the total proposal score.

Cloudification​

Higher scores reflect a greater degree of cloud adoption within the proposed solution.

Migration Effort​

The Migration Effort score estimates how much effort is required to move existing workloads or applications to the cloud. Higher scores indicate lower migration effort.

Migration Tool Support​

Assesses the availability of tools and services that support a smooth migration. Official vendor tools score higher than third-party tools or basic migration guides.

Target Architecture Size​

Reflects the ease of migration based on the size and complexity of the target architecture. Smaller stacks with fewer dependencies are generally easier to migrate.

Technical Similarity​

Evaluates how closely the target technologies align with the current technologies. Smaller changes typically result in higher scores, while more significant technology shifts may require additional effort and score lower.
