What is zero-based budgeting?

‍
Zero-based budgeting is an accounting technique that requires all expenses to be justified and approved for each financial period, starting from zero rather than a pre-existing spend. This enables organizations to monitor and assess the necessity of each cost on a more granular level, lowering expenses and promoting fiscal responsibility.

‍
Originally conceived in the 1970s, zero-based budgeting isn’t a new idea — but in the current economic climate, accounting for every dollar is helping businesses to regain control over their outgoings. The technique can be applied to a wide range of costs, from research and development to asset management.

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.

What is meant by outsourced SaaS procurement?

‍
Outsourced procurement in SaaS refers to the process of hiring a third-party vendor to manage some or all aspects of a company’s procurement process. This can involve negotiating with vendors on your behalf to secure the best possible price and terms on any SaaS contract, while also refining, implementing and enforcing procurement processes that ultimately protect your business.

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 centralized procurement in SaaS?

‍
Centralized SaaS procurement is a model in which all software purchasing decisions are made or approved by a single department, often either IT, procurement or finance. By having a streamlined process for purchasing and renewing software solutions, organizations can ensure they have total visibility of their SaaS apps, prevent wasted spend and maximize purchasing power.

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.
