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.

Maverick Buying

What is maverick buying?


Maverick spending, also known as rogue spending, can be defined as any purchasing that takes place within an organization, outside of an established procurement process.


In the context of SaaS, maverick spending refers to the acquisition of cloud-based software solutions that are purchased unbeknownst to the finance, IT or procurement teams, and in a way that does not comply with the organization’s formal IT procurement process — and so may not be approved, vetted, or appropriately documented.

Spot Instances

What are spot instances?


As with any cloud service provider, AWS will have spare capacity available to support surges in customer demand. To offset the loss, AWS offers this excess EC2 capacity – in other words, spot instances – at a heavily discounted rate.


To benefit from these spot instances, users must bid on this unused EC2 capacity in their desired region. The capacity is then allocated to the highest bidder. While it can be a great way to reduce costs by as much as 90%, it is only suitable for workloads that can tolerate interruptions and don’t require continuous availability. This is because AWS will terminate the instance after a two-minute notification in the event that it needs to reclaim the resources, or because the spot price exceeds the bid price. In other words, when other customers are willing to pay more.

Price Uplifts

What are price uplifts?


In the context of SaaS, price uplifts refer to an increase in the price of a software subscription. While many software providers will implement price uplifts on an annual basis, typically at the point of renewal, others may review and amend their pricing more frequently, for example on a quarterly basis. It is recommended that buyers negotiate a price uplift cap during the initial contract negotiation stage, placing a limit on the maximum amount the subscription can be increased by within a specified time period.
