AWS Builds on Familiarity with Leased Facilities

One might argue that the trio of edge computing approaches announced by Amazon Web Services grows directly from the way it has in the past sourced computing infrastructure, including a mix of owned and leased facilities. Along the way, AWS has had to create and get comfortable with the idea of its servers operating in somebody else’s facilities.

Up to this point, the “somebody else” has been third party data centers. But edge computing requires even more decentralized facilities. Hence, Outposts, a rack of servers managed by AWS but physically on-premises. 

The customer provides the power and network connection, but everything else is done for them. If there is a fault, such as a server failure, AWS will supply a replacement that is configured automatically. Outposts runs a subset of AWS services, including EC2 (VMs), EBS (block storage), container services, relational databases and analytics. S3 storage is promised for some time in 2020. 

Local Zone, currently only available in Los Angeles, is an extension of an AWS Region, running in close proximity to the customers that require it for low latency. Unlike Outposts, Local Zone is multi-tenant. AWS deploys only when there is a critical mass of customers unable to take advantage of an established AWS region. 

Wavelength is a physical deployment of AWS services in data centers operated by telecommunication providers to provide low-latency services over 5G networks. Operators signed up so far include Verizon, Vodafone Business, KDDI and SK Telecom.

All three services essentially are built on Outposts and local server facilities using third party sites. As AWS had to get comfortable with third party data centers hosting its servers, so Outposts extends that hosting to enterprises. 

A Local Zone is effectively a large group of outposts. Wavelength involves Outposts located inside a telco facility of some kind, likely often a central office. AWS is early to move, but the other hyperscale computing-as-a-service providers also are expected to make big moves toward edge computing facilities as well. 

By 2023, by some accounts, the hyperscale cloud computing firms will be spending $23 billion in a single year to create edge computing facilities, about half of total capex in that year.
