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.

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.
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.
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.
Overages
What are overages in SaaS?
In SaaS, overages refer to the additional costs or fees that are incurred when a user exceeds the contracted usage limits or terms of their plan. Examples of overages include user overages, storage overages, API usage overages, feature overages and support overages.
Multi-Tenancy Environment
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.
SaaS Management
What is SaaS management?
SaaS management is the process of identifying, managing, and governing the software applications that exist within an organization’s technology portfolio.
When software goes unmanaged, it not only puts the business at risk of data breaches and security issues, but it can also lead to a substantial amount of wasted spend as a result of redundant and duplicate SaaS apps, not to mention unused licenses.
