Different Gateways in Azure (Simplified)

➜ Azure Application Gateway
➜ Azure VPN Gateway
➜ Azure Firewall
➜ Azure Front Door
➜ Azure Load Balancer
➜ Azure NAT Gateway
➜ Azure Bastion
➜ Internet Gateway

What is the purpose of these??

👇👇

➜ Azure Application Gateway: This is a web traffic load balancer that operates at the application layer (OSI layer 7). It enables you to manage traffic to your web applications, providing features like SSL termination, URL-based routing, and cookie-based affinity.

➜ Azure VPN Gateway: This service allows you to establish secure, encrypted connections between your on-premises network and Azure virtual networks. It supports site-to-site, point-to-site, and VNet-to-VNet connections, using protocols like IPsec and OpenVPN.

➜ Azure Firewall: This is a cloud-native, network security service that provides inbound and outbound network traffic filtering. It can be used to protect Azure Virtual Networks and offers features like threat intelligence, URL filtering, and application control.

➜ Azure Front Door: This is a global, scalable, and secure entry point for your web applications. It provides features like SSL offloading, URL-based routing, and application acceleration.

➜ Azure Load Balancer: This is a Layer 4 load balancer that distributes incoming traffic across multiple instances of your application. It supports both internal and external load balancing and provides features like health probes and session persistence.

➜ Azure NAT Gateway: This service provides outbound connectivity for virtual machines in Azure, allowing them to communicate with the internet or on-premises networks. It simplifies the management of outbound traffic and provides features like source NAT and port address translation.

➜ Azure Bastion: This is a fully managed service that provides secure and seamless Remote Desktop Protocol (RDP) and Secure Shell (SSH) access to virtual machines in Azure. It eliminates the need for public IP addresses on your virtual machines and provides additional security features like just-in-time access and access control lists.

➜ Internet Gateway: This is a type of gateway in Azure that allows resources within a virtual network to communicate with the Internet. It provides a public IP address that can be used to access the Internet from within the virtual network.

Different Gateways in AWS (Simplified)

➜ AWS API Gateway
➜ AWS VPN Gateway
➜ AWS Transit Gateway
➜ AWS Application Load Balancer
➜ AWS Network Load Balancer
➜ AWS Internet Gateway
➜ AWS NAT Gateway
➜ AWS Direct Connect

What is the purpose of these??

👇👇

➜ AWS API Gateway: This is a fully managed service that makes it easy for developers to create, publish, maintain, monitor, and secure APIs at any scale. It handles all the tasks involved in accepting and processing up to hundreds of thousands of concurrent API calls.

➜ AWS VPN Gateway: This service provides secure connectivity between an on-premises network and AWS, using VPN connections. It supports site-to-site VPN connections and uses IPsec protocol to establish encrypted connections.

➜ AWS Transit Gateway: This allows you to connect your Amazon Virtual Private Clouds (VPCs) and on-premises networks through a central hub. It simplifies your network architecture by providing a single gateway to manage multiple VPC and VPN connections.

➜ AWS Application Load Balancer: This load balancer operates at the application layer (OSI layer 7) and routes traffic based on the content of the request. It supports path-based routing, host-based routing, and more.

➜ AWS Network Load Balancer: This load balancer operates at the transport layer (OSI layer 4) and is capable of handling millions of requests per second while maintaining ultra-low latencies. It is designed for load balancing TCP, UDP, and TLS traffic.

➜ AWS Internet Gateway: This is a horizontally scaled, redundant, and highly available VPC component that allows communication between instances in your VPC and the internet. It provides a target in your VPC route tables for internet-routable traffic.

➜ AWS NAT Gateway: This service enables instances in a private subnet to connect to the internet or other AWS services but prevents the internet from initiating a connection with those instances. It provides outbound internet access for private subnets.

➜ AWS Direct Connect: This is a cloud service solution that makes it easy to establish a dedicated network connection from your premises to AWS. Using AWS Direct Connect, you can establish private connectivity between AWS and your data center, office, or colocation environment.

DevOps Services in AWS (Simplified) 🔥🔥

➜ AWS CodeCommit
➜ AWS CodeBuild
➜ AWS CodeDeploy
➜ AWS CodePipeline
➜ AWS CodeStar
➜ AWS CloudFormation
➜ AWS CloudWatch
➜ AWS OpsWorks

What is the purpose of these??

👇👇

➜ AWS CodeCommit: This is a fully managed source control service that makes it easy for teams to host secure and scalable Git repositories. It allows you to store and manage your source code, binaries, and metadata in a secure and scalable manner.

➜ AWS CodeBuild: This is a fully managed build service that compiles source code, runs tests, and produces software packages that are ready to deploy. It can scale continuously and process multiple builds concurrently, so your builds are not left waiting in a queue.

➜ AWS CodeDeploy: This service automates code deployments to any instance, including Amazon EC2 instances and on-premises servers. It makes it easier for you to rapidly release new features, helps you avoid downtime during application deployment, and handles the complexity of updating your applications.

➜ AWS CodePipeline: This is a continuous integration and continuous delivery (CI/CD) service for fast and reliable application and infrastructure updates. CodePipeline automates the build, test, and deploy phases of your release process every time there is a code change, based on the release model you define.
