Proving scale for enterprise

Elastic Beanstalk Scaling

About

A FinTech business working with Cloud Combinator on AWS. The client is anonymised at their request.

Challenge

The challenge had three focus areas.

A scale ceiling blocking enterprise deals

The client wanted to onboard new clients and pursue contracts with large organisations, but could not yet prove the platform would cope with their volume. The target was ambitious: scaling to roughly eight to ten times the current possible workload.

No intelligent scaling in place

The application needed automated scaling policies that respond to demand, rather than fixed capacity that either wastes money at quiet times or falls over at peak. Building this on Elastic Beanstalk gave the client a managed, repeatable foundation.

Turning capability into credibility

It was not enough to configure scaling; the client needed it deployed and tested so the scalability could be demonstrated to prospective enterprise customers as evidence, not aspiration.

Solution

Cloud Combinator delivered the work through its structured Cloud Accelerator Program, a staged cadence that took the client from understanding the workload to a tested scaling capability in the account.

Target scaling headroom above current workload (target)

Cloud Accelerator Program stages, discovery through delivery

By the numbers:

  • 8-10x - Target scaling headroom above current workload (target)
  • 5 - Cloud Accelerator Program stages, discovery through delivery
  • 1 - Immersion day upskilling the client's own engineers
Changes

The engagement delivered against its acceptance criteria: intelligent Elastic Beanstalk scaling policies deployed and tested in the client's environment, with the platform's scalability demonstrated and the client's internal technical lead signed off as able to operate it. The client came away able to show, not just assert, that its platform could scale for larger customers.

  • Intelligent scaling deployed — Elastic Beanstalk scaling policies configured on a workload-optimised environment and deployed in the client's AWS account.
  • Scalability proven — The scaling capability was tested so the client could demonstrate the headroom needed to pursue larger enterprise contracts.
  • Best-practice baseline — A minimum level of best practice around security, billing and recovery, built with Cloud Combinator templates and automation.
  • Handover — An immersion day and sign-off left the client's internal team confident to operate and continue developing the solution.

With proven scaling in place, the client moved from hoping its platform would cope to being able to show prospective enterprise customers that it does, opening the door to the larger contracts it was targeting.
