A hybrid cloud deployment model involves using a combination of both public and private clouds to allow data and applications to be shared between them.

A private-direct connection to a cloud provider involves establishing a dedicated private connection that does not traverse the public internet.

Infrastructure as Code (IaC) refers to the use of software to automate the management and configuration of network infrastructure.

Elasticity in cloud computing allows resources to be adjusted dynamically based on the workload.

The main security implication of using a public cloud is the potential exposure of sensitive data to unauthorized access due to the shared nature of the infrastructure.

Scalability in cloud computing allows for the automatic adjustment of resources to meet varying demand levels.

Infrastructure as Code (IaC) allows for automation and orchestration of the deployment and management of infrastructure, reducing the need for manual configuration.

Infrastructure as a Service (IaaS) offers virtualized computing resources over the internet and allows customers to rent virtual machines and storage.

Platform as a Service (PaaS) provides a platform allowing customers to develop, run, and manage applications without dealing with the underlying infrastructure.

Desktop as a Service (DaaS) provides virtual desktops hosted by a cloud provider, allowing users to access their desktops from any device with an internet connection.

Software as a Service (SaaS) provides a complete software solution that is hosted and managed by a cloud provider, accessible over the internet.

Multitenancy in cloud computing refers to a single instance of a software application serving multiple customers (tenants), allowing them to share computing resources while keeping their data isolated.
