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 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.

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.

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 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.
