Designing an Application-Centric Infrastructure Platform:

Experience from the Field

bution

In the age of digital transformation, businesses want a competitive advantage. They rely heavily on agile

applications with just-in-time data intelligence. To meet these expectations, architects must provide platforms that are agile

across the application layer and infrastructure, along with operational excellence. It is imperative that developers and infrastructure operations work closely together to build the

necessary architecture with flexibility and robustness in mind from the beginning.

Platform Engineering Responsibilities

bution

Some Background on the following Examples

• Developers could tackle all Platform Engineering Responsibilities in each Service

– Analogy: Microsoft Exchange DAGs or SQL Server Always-on Group

– Downside: Complexity and Sprawl

• Alternative: let the Platform handle non-functional Service Requirements

– Analogy: vSphere HA

– Advantage: Common Knowledge and Methodology (Standardization)

• Examples show various Platform Engineering Approaches and simple but powerful Patterns

Example #3 – App Auto-Scaling Integration in vRealize LogInsight (vRLI)

• Uses vRLI REST API

• Auto-Scaler (“Custom Controller”) emits Events from Kubernetes to vRLI API

• Note: not a supported Integration by VMware today (Proof of Technology)
