Cloud resource management provides management of the resources quota and the ability to scale resources up and down. Resource quota is the limit on the amount of resources that a tenant can use in a cloud environment, such as CPU, memory, storage, network, etc. Resource quota helps to prevent overconsumption of resources by a single tenant and to ensure fair allocation of resources among multiple tenants. The ability to scale resources up and down means that the cloud can dynamically adjust the amount of resources allocated to a tenant based on the demand and availability. Scaling resources up and down helps to optimize the performance and efficiency of the cloud, as well as to reduce the cost and waste of resources.Reference:Nokia Bell Labs Distributed Cloud Networks,Cloud Resource Planning

Software as a Service (SaaS) is a cloud computing offering that provides users with access to a vendor's cloud-based software. Users do not install applications on their local devices. Instead, the applications reside on a remote cloud network accessed through the web or an API. Within this context, Database-as-a-Service (DBaaS) is considered a form of SaaS, where the service provider manages the database's installation, maintenance, backup, and scaling needs on behalf of the customer. Platform-as-a-Service (PaaS) provides a platform allowing customers to develop, run, and manage applications without dealing with the complexity of building and maintaining the infrastructure typically associated with developing and launching an app. PaaS can include various software components, including database management systems, and thus can be considered a subset of SaaS.

The standardization of network functions provides well defined interfaces and defined functional elements. Well defined interfaces are the specifications that describe how network functions communicate and interact with each other and with other network components. Defined functional elements are the components that perform specific tasks or functions within the network. By standardizing these aspects, network functions can achieve interoperability, compatibility, and modularity, which are essential for building and deploying network services.

The characteristics of traditional monolithic services are low scalability and fixed capacity. Monolithic services are applications that are built as a single unit, where all the components are tightly coupled and run in the same process. This makes them hard to scale, as they require more resources and coordination to handle increased demand. Monolithic services also have fixed capacity, as they are designed for a specific workload and cannot adapt to changing requirements or traffic patterns. Monolithic services are often slow to deploy, as they require updating the entire application for any change or improvement.Reference: [Cloud Native applications design], [Microservices and Containerization]
