What is an instance in the context of cloud computing?
In cloud computing, an instance refers to a virtual server provided by a third-party cloud service, for example AWS, Azure or Google Cloud. These instances ultimately enable companies to deploy and run their applications or services in the cloud, in a scalable and flexible manner. This is because instances are on-demand and can be adjusted based on your workload requirements.

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.
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.
Master Service Agreement (MSA)
What is a Master Service Agreement?
A Master Service Agreement (MSA) is a contract between two parties, in this case the software provider and the buyer, outlining the terms and conditions of the agreement. It will typically cover pricing, payment terms, service levels, intellectual property rights, confidentiality, liability, termination, and dispute resolution.
Unlike a service level agreement (SLA) which outlines the specific performance metrics and criteria for the delivery of a particular service, for example uptime guarantees and support response times, an MSA covers the broader terms of the business relationship.
Cloud Unit Economics
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.
Decentralized Procurement
What is decentralized procurement?
Decentralized purchasing in SaaS refers to the process of allowing individual departments or teams within an organization to make their own purchasing decisions for software applications. This is in contrast to a centralized purchasing model, where all purchasing decisions are approved by a single procurement team or a department such as finance.
While a decentralized purchasing model can provide teams with the flexibility to select and purchase the tools that best meet their needs, without having to wait for approvals or navigate bureaucratic purchasing processes, it can create challenges for the company. This can include reduced buying power, higher costs, lack of control over vendor relationships, and increased compliance and legal risks.
FinOps
What is FinOps?
FinOps refers to financial operations. In relation to cloud technology, Cloud Financial Operations is a practice that focuses on aligning cloud costs with business objectives and improving overall financial management in the cloud. When implemented correctly, it can provide you with a better understanding of your cloud spending patterns, enabling you to make more informed decisions on how to allocate and manage your costs.
