The box model in CSS describes the rectangular boxes generated for elements in a document tree and consists of four areas: content, padding, border, and margin. The content is the innermost area, surrounded by padding, then the border, and finally the margin, which is the outermost area.

Azure VPN Gateway is a service that allows you to create secure connections between your on-premises network and Azure through a VPN (Virtual Private Network). It encrypts the data transmitted over the internet.
When used with ExpressRoute, which provides a private connection to Azure, the VPN Gateway can serve as a backup for connectivity. If the ExpressRoute connection fails, the VPN Gateway can automatically take over to maintain connectivity, ensuring high availability and redundancy.
Azure Availability Sets are a grouping of virtual machines (VMs) that ensure high availability by distributing them across multiple physical servers in a data center, protecting against hardware failures.
Azure Availability Zones are physically separate locations within an Azure region, each with its own power, cooling, and networking, providing higher resilience and availability by allowing applications to remain operational even if one zone goes down.
Azure Active Directory (Azure AD) is a cloud-based identity and access management service from Microsoft. It helps organizations manage user identities and access to resources securely. Azure AD is used for single sign-on (SSO), multi-factor authentication (MFA), and managing user permissions across various applications and services, both in the cloud and on-premises.
Azure Blob Storage is designed for storing unstructured data like text and binary data, while Azure File Storage is designed for file shares that can be accessed via SMB (Server Message Block) protocol, allowing for file sharing across multiple machines.
A Virtual Network (VNet) in Azure is a logically isolated network that allows you to securely connect Azure resources to each other and to on-premises networks. It is configured by defining the address space, creating subnets, and setting up network security groups and routing rules as needed. You can create a VNet through the Azure portal, Azure CLI, or Azure PowerShell by specifying the desired IP address range and subnets.
Elastic Beanstalk is a platform-as-a-service (PaaS) that simplifies application deployment and management, automatically handling infrastructure provisioning, load balancing, and scaling. CloudFormation, on the other hand, is an infrastructure-as-code (IaC) service that allows you to define and provision AWS resources using templates, giving you more control over the infrastructure setup but requiring more manual configuration.
Spot instances are a type of Amazon EC2 instance that allows you to bid on unused computing capacity at potentially lower prices than on-demand instances. They can be interrupted by AWS with little notice if the capacity is needed for on-demand instances.
Amazon CloudWatch is a monitoring and management service that provides data and insights about AWS resources and applications, allowing users to collect and track metrics, set alarms, and automate responses to changes in their AWS environment.
To secure data in transit in AWS, use SSL/TLS for encryption during transmission and implement VPNs or AWS Direct Connect for secure connections. To secure data at rest, use AWS services like S3 Server-Side Encryption, EBS encryption, and RDS encryption, along with IAM policies to control access.
AWS Lambda is a serverless computing service that allows you to run code in response to events without provisioning or managing servers. It automatically scales and charges only for the compute time consumed.
