SaaS Sprawl

What is SaaS sprawl?


SaaS sprawl, also known as software sprawl, occurs when an organization’s SaaS stack consists of a large — and often unmanageable — number of applications.


Ultimately, as business needs grow, the number of digital tools required increases, which leads to new applications being subscribed to, be this through a centralized process or at the will of individual employees.

Reserved Instances

What are reserved instances?


Reserved Instances (RIs) are a pricing and capacity reservation offering provided by AWS for their EC2 (Elastic Compute Cloud) and RDS (Relational Database Service) services.


They specifically allow users to commit to using a specific instance type in the same region for either a one or three-year term, in exchange for discounts of up to 72% – the exact discount is ultimately dependent on the commitment term, instance type, availability zone and region.


There are various types of Reserved Instances available, each with different terms and levels of flexibility. Standard Reserved Instances provide the highest cost savings but are the least flexible, whereas Convertible Reserved Instances offer more flexibility by allowing you to change instance families within the same instance type.


In contrast, Scheduled Reserved Instances offer a lower discount, but allow you to reserve capacity for specific time windows, such as business hours or weekends, providing cost savings for predictable workloads.

Auto-Renewal

What is an auto-renewal clause?

Auto-renewal is a term often used in SaaS agreements referring to the automatic renewal of a user’s subscription plan at the end of their contract term. These auto-renewal clauses will automatically extend the user’s subscription for another period, typically the same duration as the initial term, unless the customer explicitly cancels or modifies their subscription by a specified date. This is often referred to as a termination window and is typically either 30, 60 or 90 days prior to the renewal date.

Tail Spend

What is tail spend?


Tail spend refers to the unmanaged purchases made within an organization that fail to pass through an official procurement process. On account of their low value, the costs incurred by these purchases are seldom monitored by financing teams as they are generally too small to be deemed “strategic”. The problem, however, is that they can make up as much as 20% of a business’ total spend.
