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.

Service Level Agreement (SLA)
What is a service level agreement in SaaS?
A Service Level Agreement (SLA) is a subset of a Master Service Agreement (MSA) and contains specific details about the level of service that will be provided by the SaaS vendor. This agreement will specifically define the performance metrics, responsibilities, and expectations of both parties.
An SLA is likely to include uptime guarantees, the level of support that will be provided to the customer, response times for any support requests, information on how these requests will be managed and escalated, information on how the vendor will protect the customer’s data and ensure the security of its systems and networks, as well as details on how it will compensate the customer if it fails to meet the agreed-upon service levels.
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.
Break Clause
What is a break clause?
A break clause refers to a provision within a SaaS agreement that allows either the customer or the SaaS provider to terminate the contract before the end of the initial term. A break clause will typically set out the conditions or requirements that must be met for either party to exercise their right to terminate an agreement early. For example, a break clause can enable users to cancel their subscription if they are dissatisfied with the service.
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.
Reduction Clause
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.
SaaS Sprawl
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.
