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 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 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.

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 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 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.
