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.

What is cloud unit economics?

‍
By definition, cloud unit economics refers to the financial analysis and evaluation of both the costs and revenue associated with operating a cloud-based business.

‍
In other words, it’s a way of looking at how much it costs to run your business on the cloud, as well as how much it brings in.

What is a break clause?

‍
A break clause refers to a provision within a SaaS agreement that allows either the customer or the SaaS provider to terminate the contract before the end of the initial term. A break clause will typically set out the conditions or requirements that must be met for either party to exercise their right to terminate an agreement early. For example, a break clause can enable users to cancel their subscription if they are dissatisfied with the service.

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.

What is a SaaS agreement?

‍
A SaaS agreement, or contract, details the terms of your purchase from a SaaS vendor.

What is SaaS management?

‍
SaaS management is the process of identifying, managing, and governing the software applications that exist within an organization’s technology portfolio.

‍
When software goes unmanaged, it not only puts the business at risk of data breaches and security issues, but it can also lead to a substantial amount of wasted spend as a result of redundant and duplicate SaaS apps, not to mention unused licenses.
