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 multi-tenancy environment?

‍
In cloud computing, a multi-tenancy environment refers to a situation where multiple users, also referred to as tenants, share the same physical infrastructure and resources. These resources, such as computing power, memory and storage are dynamically allocated based on the needs of each tenant. Each tenant’s data is, however, stored in separate databases to ensure both privacy and security.

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 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.

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.

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.
