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.
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.
