Multi-Tenancy Environment

What is decentralized procurement?

‍
Decentralized purchasing in SaaS refers to the process of allowing individual departments or teams within an organization to make their own purchasing decisions for software applications. This is in contrast to a centralized purchasing model, where all purchasing decisions are approved by a single procurement team or a department such as finance.
While a decentralized purchasing model can provide teams with the flexibility to select and purchase the tools that best meet their needs, without having to wait for approvals or navigate bureaucratic purchasing processes, it can create challenges for the company. This can include reduced buying power, higher costs, lack of control over vendor relationships, and increased compliance and legal risks.

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.

What is centralized procurement in SaaS?

‍
Centralized SaaS procurement is a model in which all software purchasing decisions are made or approved by a single department, often either IT, procurement or finance. By having a streamlined process for purchasing and renewing software solutions, organizations can ensure they have total visibility of their SaaS apps, prevent wasted spend and maximize purchasing power.

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.

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.

What is Cloud Cost Optimization?

‍
Cloud cost optimization refers to the process of reducing and optimizing cloud spending, while ensuring optimal resource utilization and maintaining desired performance levels. It ultimately involves managing cloud costs without compromising business objectives or user experience.
