A Spectrum of SRE Implementation models
A significant aspect of SRE implementation at
Enterprise is around the model that will enable governance and growth at pace. In
this article we will look at the Hub and Spoke model as an approach to solve
the SRE scalability challenges towards applying a product management life
approach that enables rapid, repeatable SRE practices that are cross-pollinated
from the spokes that are usually across business domains.
The Hub
& Spoke model not only decentralizes the implementation of solutions, but
it also allows for rapid innovation / sharing of ideas across the organization,
while centralizing research for latest best practices. It helps attract,
develop, and retains scarce SRE talent, allowing for flexible allocation of
resources to keep employees challenged with new perspectives.
A few considerations are as below, as SRE capabilities mature, the governance model
will evolve with more talent sitting in the spokes, meaning more work completed
by the business sectors & the hub acting as a champion available when
needed.
The SRE HUB
exists to enable self-service model for the spokes. Typically built using the
in-source model that builds embedded governance that is fit for purpose, the
cross-pollination from spokes is key to following the product-based approach by
the HUB.
