A VPC (Virtual Private Cloud) is a virtual network dedicated to your AWS account, allowing you to launch AWS resources in a logically isolated environment.

Amazon Route 53 is a scalable and highly available Domain Name System (DNS) web service that translates domain names into IP addresses, helping to route end users to Internet applications.
EC2, or Amazon Elastic Compute Cloud, is a web service that provides resizable compute capacity in the cloud, allowing users to run virtual servers and manage applications on-demand.
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.
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.
The different types of networks in Google Cloud Platform (GCP) are:
1. **VPC Networks** (Virtual Private Cloud)
2. **Subnets** (Subnetworks)
3. **Peered Networks** (VPC Peering)
4. **Shared VPC Networks**
5. **Hybrid Connectivity** (VPN and Interconnect)
6. **Serverless VPC Access**
7. **Cloud VPN**
8. **Cloud Interconnect**
The different storage options in Google Cloud Platform (GCP) include:
1. Google Cloud Storage (Object Storage)
2. Google Persistent Disk (Block Storage)
3. Google Filestore (File Storage)
4. Google Bigtable (NoSQL Database)
5. Google Cloud SQL (Relational Database)
6. Google Cloud Spanner (Scalable Relational Database)
7. Google Firestore (NoSQL Document Database)
8. Google Cloud Datastore (NoSQL Database for web and mobile apps)
Cloud NAT (Network Address Translation) is a Google Cloud service that allows private IP instances to access the internet for outbound traffic without exposing their private IP addresses. It enables these instances to communicate with external services while keeping them secure and private by translating their private IP addresses to a public IP address for outbound requests.
Shared VPCs allow organizations to share a Virtual Private Cloud (VPC) network across multiple projects within Google Cloud. You would use them to centralize network management, enhance security, and simplify resource sharing among different teams or projects while maintaining control over the network.
Cloud SQL is a fully managed relational database service for SQL databases like MySQL and PostgreSQL. Cloud Spanner is a horizontally scalable, globally distributed relational database that supports SQL queries and strong consistency. Bigtable is a NoSQL database designed for large analytical and operational workloads, optimized for high throughput and low latency.
To implement backup and disaster recovery in Azure, use Azure Backup to create and manage backups of your data and applications. For disaster recovery, utilize Azure Site Recovery to replicate and failover your virtual machines and applications to a secondary location. Ensure to regularly test your backup and recovery processes to validate their effectiveness.
Azure Load Balancer operates at the transport layer (Layer 4) and distributes incoming network traffic across multiple servers, while Azure Application Gateway operates at the application layer (Layer 7) and provides features like URL-based routing, SSL termination, and Web Application Firewall (WAF) capabilities.
A Virtual Network (VNet) in Azure is a logically isolated network that allows Azure resources to securely communicate with each other, the internet, and on-premises networks. It is configured by defining the address space (IP range), creating subnets, and setting up network security groups (NSGs) to control traffic. Configuration can be done through the Azure portal, Azure CLI, or Azure PowerShell.
Azure Load Balancer operates at the transport layer (Layer 4) and distributes incoming traffic based on IP address and port, while Azure Application Gateway operates at the application layer (Layer 7) and provides features like URL-based routing, SSL termination, and Web Application Firewall (WAF) capabilities.
Azure DNS is a cloud-based domain name system service provided by Microsoft Azure that allows you to host your DNS domains and manage DNS records using the Azure portal or APIs. It enables you to resolve domain names to IP addresses and manage domain-related settings, ensuring high availability and performance for your applications.
