Establishing a FinOps Practice: A Practical Guide for Modern Cloud Driven Organisations

A Practical Guide for Modern Cloud Driven Organisations

For most organisations, the real challenge of cloud isn’t the cost itself, but the lack of financial accountability and oversight in how cloud decisions are made. Whether a business has already migrated to public cloud or is just beginning its cloud transformation, leaders are increasingly realising that their original cost expectations rarely match reality. As cloud usage grows, so too does the urgency to build financial accountability into the way technology teams operate. This is where FinOps helps organisations take control of cloud spend by aligning usage, cost and business value across technology and finance teams.

Understanding What FinOps Really Is

FinOps is often mistaken for cloud cost optimisation or reporting, but it is a strategic discipline that aligns cloud spending with business value. A mature FinOps practice creates a culture where teams understand the financial impact of technical decisions, engineering feels ownership of cloud usage, and collaboration between finance and technology becomes part of everyday work.

To succeed, a FinOps function must blend several capabilities: strong cloud and infrastructure knowledge; financial and commercial literacy; stakeholder management; data analytics; and understanding of FinOps and automation platforms.

Building this mix of skills internally takes time and the right people. Organisations must consider not just cost, but readiness. So, how do you decide between building an in‑house team and bringing in a consultancy?

How do we build an effective FinOps team?

It’s not a simple question, because establishing a successful FinOps practice requires far more than appointing a cost‑focused analyst or implementing a reporting tool. It demands skills, cultural alignment, and an operating model that embeds financial responsibility across engineering, product, and finance teams. While every organisation’s journey is unique, most paths fall into three categories: building internal capability, partnering with specialists, or adopting a hybrid approach that evolves over time.

For many organisations, owning FinOps internally is the long‑term ideal. Internal teams understand the business context better than any external partner; the systems, history, quirks, and people involved, which often makes them more effective at influencing behaviours and driving lasting cultural change.

But building a FinOps team from scratch is difficult. Skilled practitioners are scarce, and hiring the right mix of cloud, financial, and analytical expertise can take months. Even once in place, creating the FinOps frameworks, governance models and the reporting pipelines to establish the communication channels can take time. During this period, cloud costs continue to grow, and organisations may struggle to capture value quickly.

If rapid progress is essential, or existing teams are stretched, building internally can delay results.

Many companies accelerate their journey by partnering with a specialist consultancy or managed FinOps provider. This brings immediate access to skilled professionals who have built and run FinOps capabilities across multiple industries, along with proven methodologies, tooling strategies, and reporting pipelines.

The primary advantage is speed. A consultancy can rapidly assess cloud environments, identify optimisation opportunities, and establish foundational processes. There’s no lengthy recruitment, no need to upskill teams before seeing value, and less risk of early missteps slowing progress.

However, outsourced models aren’t perfect. Without developing internal capability, the FinOps practice may remain dependent on external support and struggle to embed culturally. These engagements also come with a cost, and a prearranged duration, meaning long‑term success requires clear planning around knowledge transfer and internal ownership.

In reality, the most effective approach for organisations can be a hybrid model. By combining external expertise with internal capability building, companies can accelerate early wins while still developing sustainable long-term ownership.

A hybrid model typically follows this pattern:

This approach offers speed without sacrificing internal maturity. It’s particularly valuable in organisations operating across Azure, AWS, or multi-cloud platforms, where specialist knowledge is essential.

Telefónica Tech provides flexible FinOps support tailored to an organisation’s maturity, from short-term accelerators to fully managed services or co‑delivery models that build internal capability. Our team combines cloud architecture expertise, financial accountability, and practical FinOps experience across Azure, AWS, and multi‑cloud environments, working with engineering, product, and finance teams to integrate FinOps into everyday operations.
