AWS Site-to-Site VPN Integrations

Amazon Web Services (AWS) is the world’s most comprehensive cloud platform, trusted by millions of customers across industries. From startups to global enterprises and government agencies, AWS provides on-demand solutions for compute, storage, networking, AI, analytics, and more. The platform empowers organizations to innovate faster, reduce costs, and scale globally with unmatched flexibility and reliability. With services like Amazon EC2 for compute, Amazon S3 for storage, SageMaker for AI/ML, and CloudFront for content delivery, AWS covers nearly every business and technical need. Its global infrastructure spans 120 availability zones across 38 regions, ensuring resilience, compliance, and security. Backed by the largest community of customers, partners, and developers, AWS continues to lead the cloud industry in innovation and operational expertise.

Amazon CloudWatch is a monitoring and observability service built for DevOps engineers, developers, site reliability engineers (SREs), and IT managers. CloudWatch provides you with data and actionable insights to monitor your applications, respond to system-wide performance changes, optimize resource utilization, and get a unified view of operational health. CloudWatch collects monitoring and operational data in the form of logs, metrics, and events, providing you with a unified view of AWS resources, applications, and services that run on AWS and on-premises servers. You can use CloudWatch to detect anomalous behavior in your environments, set alarms, visualize logs and metrics side by side, take automated actions, troubleshoot issues, and discover insights to keep your applications. CloudWatch alarms watch your metric values against thresholds that you specify or that it creates using ML models to detect anomalous behavior.

AWS Client VPN is a fully managed remote access VPN solution used by your remote workforce to securely access resources within both AWS and your on-premises network. Fully elastic, it automatically scales up or down based on demand. When migrating applications to AWS, your users access them the same way before, during, and after the move. AWS Client VPN, including the software client, supports the OpenVPN protocol. Many organizations require multi-factor authentication and federated authentication from their VPN solution. AWS Client VPN supports these and other authentication methods. Traditional on-premises VPN services are limited by the capacity of the hardware that runs them. AWS Client VPN is a pay-as-you-go cloud VPN service that elastically scales up or down based on user demand. Unlike on-premises VPN services, AWS Client VPN allows users to connect to AWS networks using a single VPN connection.

AWS Transit Gateway is a fully managed service that connects Amazon Virtual Private Clouds (VPCs) and on-premises networks through a central hub, simplifying network architecture and eliminating complex peering relationships. Acting as a scalable cloud router, it allows each new connection to be made only once. Transit Gateway supports dynamic and static layer 3 routing between VPCs and VPNs, with routes determining the next hop based on the destination IP address. It enables VPN connections between the Transit Gateway and on-premises gateways, supporting Equal Cost Multipath (ECMP) routing to increase bandwidth by load-balancing traffic over multiple paths. AWS Transit Gateway Connect facilitates native integration of Software-Defined Wide Area Network (SD-WAN) appliances into AWS using standard protocols like GRE and BGP, enhancing bandwidth and supporting dynamic routing.

Amazon Virtual Private Cloud (Amazon VPC) is a service that lets you launch AWS resources in a logically isolated virtual network that you define. You have complete control over your virtual networking environment, including selection of your own IP address range, creation of subnets, and configuration of route tables and network gateways. You can use both IPv4 and IPv6 for most resources in your virtual private cloud, helping to ensure secure and easy access to resources and applications. As one of AWS's foundational services, Amazon VPC makes it easy to customize your VPC's network configuration. You can create a public-facing subnet for your web servers that have access to the internet. It also lets you place your backend systems, such as databases or application servers, in a private-facing subnet with no internet access.

AWS Global Accelerator is a networking service that helps you improve the availability, performance, and security of your public applications. Global Accelerator provides two global static public IPs that act as a fixed entry point to your application endpoints, such as Application Load Balancers, Network Load Balancers, Amazon Elastic Compute Cloud (EC2) instances, and elastic IPs. Take advantage of the performance, security, and availability of the AWS Global Infrastructure to onboard your user traffic at one of the Global Accelerator edge locations. Users can access your application endpoints through static IP addresses to enjoy deterministic routing independent of DNS.

AWS VPN enables secure connections between on-premises networks and AWS Virtual Private Clouds (VPCs) using IPsec VPN tunnels. Each connection includes two tunnels for high availability, terminating in different availability zones to ensure resilience. It supports both static and dynamic routing with BGP, and offers customizable tunnel options, including inside tunnel IP addresses, pre-shared keys, and BGP Autonomous System Numbers (ASNs). Accelerated Site-to-Site VPN leverages AWS Global Accelerator to route traffic through the nearest AWS edge location, improving performance by reducing latency and jitter. AWS Client VPN is a fully managed, elastic VPN service that allows users to securely access AWS and on-premises resources from any location using an OpenVPN-based client. It supports authentication through Active Directory, mutual certificate authentication, and SAML-based federated authentication.
