Overview - Amazon EC2 Overview and Networking Introduction for Telecom Companies


Many telecom providers are in the process of building out 5G network infrastructure, assessing their mobile edge computing (MEC) strategy, and moving more of their IT workloads to the cloud. Similarly, AWS has announced AWS Outposts, a new service that runs AWS services on-premises and can be used to provide network functions virtualization infrastructure (NFVI) and MEC. With these trends, there is a need for telecom networking engineers to understand AWS elastic computing and its performance characteristics as well as AWS networking services, such as Amazon Virtual Private Cloud (Amazon VPC), AWS Transit Gateway, and AWS Direct Connect (DX). These services allow telecom providers to securely connect their on-premises environments to the cloud and achieve the high availability and performance they require.

In considering NFVI deployments, telecom providers have specific demands and require specific features, such as single root I/O virtualization (SR-IOV), Data Plane Development Kit (DPDK), Anti-affinity group support, Non-Uniform Memory Access (NUMA), and CPU pinning. They also require packet per second (pps) performance that can extend to 100 Gbps+. This whitepaper explains the performance characteristics and evolution of these features across the different elastic compute instance families. This paper assumes a basic understanding of networking concepts, such as virtual private networks (VPNs), and explains how AWS networking relates to what networking engineers do daily in running internal IT and large-scale WAN infrastructures.

Amazon VPC is a logically isolated environment in the AWS Cloud that gives telecom providers complete control over how they allocate their subnets, configure routing, and implement security through access control lists (ACLs) and security groups. AWS Transit Gateway allows inter-VPC and VPC to on-premises environments connectivity at scale.

Finally, services such as DX and VPNs allow telecom providers to connect their environments to the AWS Cloud in a secure and scalable manner, without compromising on availability. This paper also provides an example of an OSS workload running in Amazon VPC and communicating with the telecom provider’s network using DX.
