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.

Single-Tenancy Environment
What is a single-tenancy environment in cloud computing?
A single-tenancy environment, also known as dedicated hosting or a dedicated instance, refers to a situation where each user or tenant has their own dedicated infrastructure and resources, including servers, storage and network components. These resources aren’t shared with any other users, maximizing performance and control.
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.
Data Storage
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.
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.
Pricing Benchmarks
What are pricing benchmarks?
In SaaS, price benchmarking often refers to the process of comparing the cost of software to that of an alternative provider. Using this insight, buyers may be able to leverage a more favorable counteroffer from their vendor of choice. The most effective approach to benchmarking prices and securing the best possible deal on any subscription, however, is to find out what other similar companies are actually paying for the software.
Maverick Buying
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.
