An industrywide power crunch is changing how Amazon runs its e-commerce empire

Amazon's immense e-commerce business is redesigning its unreality setup arsenic powerfulness and information halfway capacity go progressively constrained.

The multiyear effort, known internally arsenic "Region Flex," intends to trim the attraction of Amazon's online unit operations successful a fistful of ample AWS regions and tally systems crossed much locations astatine a smaller scale, according to soul readying documents obtained by Business Insider.

Internal plans see efforts to trim Amazon e-commerce footprint successful awesome AWS hubs specified arsenic Northern Virginia and Dublin, Ireland, according to the documents.

The AI boom has sparked an industrywide scramble for powerfulness and computing capacity. Amazon is racing to grow AWS information centers and says it added much capacity globally than immoderate different institution past year. Even so, CEO Andy Jassy said past period that AWS still can't build capacity accelerated capable to meet demand.

"AWS powerfulness constraints"

Region Flex whitethorn not person started owed to industrywide powerfulness constraints caused by the AI boom, but the soul documents obtained by Business Insider show this has go a driving unit down the project.

The Amazon soul documents explicitly mention powerfulness and capacity constraints successful its unreality readying for the e-commerce business.

One readying archive from past twelvemonth said online unit teams were investing successful moving infrastructure retired of AWS's Dublin region "to mitigate description consequence owed to AWS powerfulness constraints."

A abstracted online market squad archive said Region Flex was required to guarantee Amazon could meet "projected capacity requirements successful each region."

Amazon's e-commerce logistics statement described Region Flex arsenic dividing its "service architecture footprint" truthful it could tally "in much AWS regions astatine a smaller scale, successful person proximity to our customers," according to 1 readying archive from earlier this year.

'S-Team goal'

Region Flex is being tracked by Amazon's astir elder leaders.

Amazon's market business described the inaugural arsenic an "S-Team goal," referring to Amazon's elder activity team, and said teams were readying much than 100 package migrations. The documents besides picture Region Flex arsenic improving resilience during AWS disruptions.

The industrywide AI roar has sent request for computing infrastructure soaring while energy and disposable information halfway abstraction person go awesome constraints connected description .

Vacancy rates crossed North America's largest information halfway markets fell to a grounds 1.4% astatine the extremity of 2025, according to CBRE. Limited powerfulness readiness is pushing much information centers beyond established hubs into smaller markets wherever energy tin beryllium secured much quickly.

Amazon is adding tremendous amounts of infrastructure to meet demand. In October, the institution said it had added much than 3.8 gigawatts of information halfway capacity complete the erstwhile year, doubling its unreality standard since 2022, and expects to astir double its powerfulness capacity again by the extremity of 2027.

Distributing workloads

Dublin has been 1 attraction of Region Flex. Ireland became 1 of Europe's biggest information halfway markets complete the past decade, putting important unit connected the country's energy system.

An soul scheme past twelvemonth called for reducing the Dublin infrastructure footprint of Amazon's e-commerce cognition by 40% done migrations and deprecations successful 2025. It besides contemplated afloat moving distant from Dublin by the extremity of 2026 and from AWS regions successful Northern Virginia and Oregon by 2029.

In an email to Business Insider, an Amazon spokesperson confirmed Region Flex. The spokesperson added that charismatic soul Amazon documents don't ever bespeak existent plans and described immoderate of the timelines and different specifications successful the documents obtained by Business Insider arsenic "not accurate."

"Evolving our infrastructure is thing caller — it's thing we've done for years to present the acquisition our customers expect from Amazon," the spokesperson said.

Using much AWS regions gives Amazon's online unit business greater elasticity to meet customer demand, amended reliability, negociate costs, and bring services person to customers, according to the spokesperson.

The soul documents show Amazon moving workloads from its long-established Dublin hub and distributing them crossed much AWS regions, including Frankfurt and Zaragoza, Spain.

That tin beryllium much expensive. Some services moving from Dublin into those 2 different regions could spot infrastructure costs emergence 10% to 15%, according to 1 document, because distributing workloads tin trim hosting efficiency. Amazon besides estimated $90 cardinal successful one-time spending connected Region Flex successful 2025, according to an soul readying document.

Distributing workloads doesn't needfully destruct capacity problems. One of the documents noted "capacity constraints" successful the Zaragoza region meant the statement planned to move only 65% of its remaining infrastructure costs there, leaving 35% successful Dublin.

Despite AWS's accelerated description , the institution still expects shortages to persist. Jassy called powerfulness the "single biggest constraint" past year, and said request will proceed to outstrip proviso during past month's net call.

"Even astatine that amount, we will still not person capable capacity to meet each the request we person successful 2026," Jassy said, adding that he expected the aforesaid move successful 2027.
