Deciding on an approach to cloud networking and content delivery can be complex, especially if you’re used to managing and configuring networks with on-premises hardware. Fortunately, building networks in the cloud shares core concepts with building on-premises, such as IP addressing, load balancing, and routing. Familiarity with these concepts will help you understand what AWS services you need.

Amazon Web Services (AWS) offers 20+ purpose-built networking and content delivery services that you can use to build, operate, and secure your cloud networks across all your cloud environments and distributed cloud and edge locations globally. You can also build network infrastructure that extends your on-premises environment to AWS.

This decision guide will help you ask the right questions to choose the networking and content delivery services and tools that fit your needs.

This video provides a four-minute introduction to AWS networking.

Understand

What you build in AWS depends on your business needs. In this guide, we use the term workloads to refer to any collection of resources and code that delivers business value, such as a customer-facing application or a backend process.

Networking and content delivery services at AWS fall into four categories: networking foundations, global and hybrid connectivity, edge networking and content delivery, and application networking.

Networking foundations

In AWS, your workloads run inside one or more Amazon Virtual Private Cloud (VPCs). After your workloads are running in VPCs, you can connect the workloads to other VPCs—such as an AWS Transit Gateway—or you can connect them to software as a service (SaaS) services including other AWS services, such as AWS PrivateLink. Amazon VPC lets you provision a private, isolated section of the AWS Cloud where you can launch AWS resources in a virtual network using customer-defined IP address ranges. Amazon VPC gives you several options for connecting your AWS virtual networks with other remote networks.

Global and hybrid connectivity

You can use the services in this category to securely connect from on-premises networks to your workloads in the AWS Cloud. You can create a virtual private network (VPN) to connect remote users by using AWS Client VPN, connect on-premises networks using AWS Site-to-Site VPN, or build a global wide area network (WAN) with AWS Cloud WAN. You can also set up a direct, private connection to the AWS Cloud using AWS Direct Connect, providing a direct, secure connection to the cloud with predictable performance. You may also need to connect your on-premises data centers, remote sites, and the cloud. A hybrid network can connect these different environments.

Edge networking and content delivery

Services in this category help ensure higher performance through caching and optimized transport. A good example of this is Amazon CloudFront. You'll also want to see customer traffic optimally routed to provide availability using services such as Amazon Route 53. Additionally, it's important that customer traffic is routed to make the most of the AWS global infrastructure using services such as AWS Global Accelerator. AWS Data Transfer Terminal is a network-ready, physical location where you can bring your data storage devices for fast data transfer to and from the AWS Cloud.

Application networking

As you increase adoption of the AWS Cloud, you’ll want to consider how to connect workloads at scale, by using AWS App Mesh and Amazon VPC Lattice, integrate the workloads in your VPCs with APIs by using Amazon API Gateway, and manage the IP address usage of the resources running in your VPCs by using Amazon VPC IP Address Manager (IPAM). As customer demand increases, you can help ensure that the workloads in your VPCs can scale and provide high availability by using Elastic Load Balancing.

Networking security and remote access

While Amazon VPC helps you secure access to your workloads, the services in this category offer enhanced protection against threat actors and unauthorized users by using AWS Network Firewall, AWS Shield, AWS Verified Access, and AWS WAF. To help ensure network security, consider using Amazon Route 53 DNS Firewall, AWS Network Firewall, AWS Firewall Manager, network access control lists, and security groups.

Consider

It's important that you choose the networking services that fit your business needs. The following are some of the criteria to consider when choosing networking services.

Business objectives

The networking services that you choose will depend on your business objectives. Assess where you are now and where you want to be when it comes to the security, reliability, accessibility, and performance of your workloads running in the AWS Cloud.

Consider how the network services you use fit with your migration and integration strategies. A hybrid networking architecture can help you meet this need by integrating your on-premises data center and AWS.

Workload characteristics

The networking services that you choose will depend on the characteristics of your workloads.

Networking services each have a particular role. Services such as AWS Cloud WAN and AWS Transit Gateway are suited for connecting workloads that are running in VPCs. Amazon API Gateway creates public APIs so that your customers can connect to your workloads. AWS Global Accelerator can help you improve the reliability, security, and latency of your workloads.
As the internet continues to grow, so does the need for IP addresses for devices. The most common format for IP addresses is IPv4. The latest format for IP addresses is IPv6. IPv6 provides more address space and solves the problem of IPv4 address exhaustion. AWS services support for IPv6 includes support for dual stack configuration (IPv4 or IPv6) or IPv6 only configurations. The number of AWS services that support IPv6 is growing continuously. To view the current services that support IPv6, see AWS services that support IPv6.

Data protection

It’s important to consider the protection of your data in the AWS Cloud.

Businesses must protect customer data against evolving cyber risks. While Amazon VPC helps you to secure access to the workloads running in VPCs, consider enhanced data protection measures, such as AWS Network Firewall, AWS Shield, AWS WAF, and Amazon Route 53 Resolver DNS Firewall.
It's recommended that you employ application-level encryption (TLS), irrespective of the transport, as a defense in depth measure to help ensure confidentiality end-to-end.
If the workloads in your VPCs need to connect to other AWS services, you can connect to those services programmatically by using API endpoints over the public internet. However, if you want to send data over a private connection, use AWS PrivateLink. Many members of the AWS Partner Network offer their SaaS solutions through AWS PrivateLink.

Availability

Availability is an application’s ability to maintain uptime. It’s important that your customers can use the products and services that you build in your VPCs with minimal or no downtime.

The AWS global infrastructure is built on AWS Regions and Availability Zones. When you deploy your workloads to your VPCs, you should deploy to multiple Availability Zones to ensure that your workload is still available in the event of a single Availability Zone failure.
To improve the availability, scalability, security, and performance of the workloads running in your VPCs, consider load balancing (Elastic Load Balancing). You can use different types of load balancers depending on the needs of your applications. Each load balancer supports different types of traffic over different protocols and network layers aligned to the Open Systems Interconnection (OSI) model. For more information about the differences between load balancer types, see product comparisons.

Performance

You can use networking services to optimize for the latency, throughput, and bandwidth requirements of your workloads running on the AWS global infrastructure.

If you want to minimize latency to local customers using web applications around the globe, consider using Amazon CloudFront. CloudFront is a content delivery network that delivers content to customers with the lowest latency possible.
If you’re running gaming, Internet of Things (IoT), or Voice over IP (VoIP) workloads, consider using AWS Global Accelerator. This service helps you improve your workloads’ availability and performance.
If the workloads in your VPCs need to connect to other AWS Regions, you can connect to those services programmatically using public API endpoints.

Operational excellence

As you increase AWS Cloud adoption, you’ll want to understand what is happening across your workloads at any time. Tools and services such as Reachability Analyzer and Amazon CloudWatch Internet Monitor can help you keep pace with changing business needs and priorities as your workloads grow.

Managing IP addresses of workloads running in multiple VPCs can be difficult. Consider if you need to automate IP address management across your workloads (Amazon VPC IPAM).
If you’re using a microservice architecture, managing the connectivity, security, and monitoring between microservices can be a challenge. Consider if you need to automate microservice interaction (AWS App Mesh and Amazon VPC Lattice).

Connectivity

You can use networking services to connect to the AWS Cloud, connect workloads, or connect networks.

Consider the following for connecting to the AWS Cloud:
- If you want to securely connect remote users to your VPCs, consider using AWS Client VPN.
- If you want to securely connect an entire on-premises network to your VPCs, consider using AWS Site-to-Site VPN.
- If you require more consistent performance than the internet can provide, consider a direct connection from your on-premises network to AWS (AWS Direct Connect).
- If you need to quickly move data into or out of the AWS Cloud, consider using AWS Data Transfer Terminal.

Consider the following for connecting networks:
- If you operate in multiple AWS Regions, want to manage your own routing configurations, or prefer to use your own automation, consider using AWS Transit Gateway.
- If you want to unify your data center, branch, and AWS networks with a WAN, consider using AWS Cloud WAN. It is also worth considering if you don't want to manage complex routing configurations or build your own automations for multi-Region connectivity.

Security

AWS provides a secure foundation for you to build and deploy your applications, but you are responsible for implementing your own security measures to protect your data, applications, and networking infrastructure, no differently than you would in an on-site data center.

Review and understand the AWS Shared Responsibility Model and how it applies to security in the AWS Cloud.
AWS security groups and network access control lists (NACLs) can be used together or on their own to secure a network, helping you to create a defense in depth security strategy.
Businesses must protect their network applications against evolving cyber risks. Consider if you will need to protect your workloads against malicious attacks or malware (with AWS Network Firewall), distributed denial of service (DDoS) attacks (with AWS Shield), or SQL injection and cross-site scripting attacks (with AWS WAF).

Amazon Route 53, AWS Firewall Manager, network access control lists, and security groups are also important to consider in ensuring network security.
