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.

Cloud Instances

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.

Auto-Scaling

What is auto-scaling?


Auto-scaling refers to the automatic adjustment of cloud computing resources based on an organization’s current demand and workload. It dynamically adjusts the allocation of resources to match the evolving requirements of an application or system without the need for manual intervention.


There are a number of benefits to using auto-scaling, the first being cost efficiency. By ensuring that resources are scaled up or down as and when needed, organizations can avoid over-provisioning and subsequently reduce unnecessary expenses. It also helps maintain consistent performance levels by automatically adding resources during peak demand periods.

Auto-Renewal

What is an auto-renewal clause?

Auto-renewal is a term often used in SaaS agreements referring to the automatic renewal of a user’s subscription plan at the end of their contract term. These auto-renewal clauses will automatically extend the user’s subscription for another period, typically the same duration as the initial term, unless the customer explicitly cancels or modifies their subscription by a specified date. This is often referred to as a termination window and is typically either 30, 60 or 90 days prior to the renewal date.

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.
