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 reduction clause?

‍
A reduction clause refers to a provision in a software agreement that allows customers to reduce the number of licenses or users covered by their subscription during the term of an agreement. This provides customers with flexibility to adjust their plan to meet evolving business needs, while avoiding paying for licenses or users they no longer require or needing to terminate the contract. The specific terms and requirements of a reduction clause may vary depending on the SaaS provider and the subscription agreement, for example it may be subject to a minimum number of licenses or users.

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 Cloud Cost Optimization?

‍
Cloud cost optimization refers to the process of reducing and optimizing cloud spending, while ensuring optimal resource utilization and maintaining desired performance levels. It ultimately involves managing cloud costs without compromising business objectives or user experience.

What is meant by data storage?

‍
In the context of cloud computing, data storage refers to the process of storing and managing digital information in either a remote server or a data center provided by a cloud service provider such as Amazon Web Services (AWS) or Microsoft Azure.

‍
The cloud ultimately provides a versatile platform for storing various types of data, whether that be documents, media files, application data, machine learning data or structured data.

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.
