Las Vegas, Nov 29 (UiTV/IANS) – Amazon Web Services (AWS) will return more water to communities than it uses in direct operations at its data centres and Cloud operations, its CEO Adam Selipsky has said.
Addressing the “AWS Re:Invent 2022” conference here, Selipsky said that water scarcity is a major issue around the world.
“With today’s water positive announcement, we are committing to do our part to help solve this rapidly growing challenge,” said Selipsky on the first day of the flagship conference late on Monday.
“In just a few years half of the world’s population is projected to live in water-stressed areas, so to ensure all people have access to water, we all need to innovate new ways to help conserve and reuse this precious resource,” he noted.
For AWS operations, water is an essential resource. It’s primarily used for cooling data centres around the world.
The Amazon company has committed to be water positive by 2030 and so far, AWS-funded replenishment projects have returned nearly 2.4 billion litres of water to communities and the environment.
MIT researchers estimate that 52 per cent of the world’s projected 9.7 billion people will live in water-stressed areas as a result of climate change by 2050.
Under the new water positive pledge, AWS said it was putting in place a water use efficiency (WUE) metric of “0.25 litres of water per kilowatt-hour” as a display of its “leadership in water efficiency” among cloud providers.
As a principal mechanical engineer, Suresh Soundararaj’s job is to design the efficient cooling systems for the AWS data centres. He said that in an ideal world, AWS wouldn’t use any water at all, but water is a crucial tool for cooling.
“An AWS data center is a labyrinth of servers, routers, and networking cables, and all this hardware gets pretty hot, so we need to cool it,” said Soundararaj. “One of the ways we do this is with water.”
The preferred cooling strategy for AWS data centers uses evaporative technologies.
In this system, hot air is pulled from outside and pushed through water-soaked cooling pads.
The water evaporates and cools the temperature of the air sent to the server rooms.
AWS also invests in on-site water-treatment systems that remove scale-forming minerals and allow the company to recycle more water on-site and minimise the water consumed for cooling.
To further improve water efficiency, AWS uses real-time water use data to identify leaks, pilot new treatment technologies, and explore a range of operational changes, according to the company.
AWS is also working to reach net-zero carbon emissions by 2040 as part of The Climate Pledge, which Amazon committed to in 2019.
Digital Sovereignty Pledge to protect customers’ assets in Cloud
In a bid to give its customers more control over their digital assets, Amazon Web Services (AWS), the Cloud arm of Amazon, has announced ‘Digital Sovereignty Pledge,’ a commitment to offer its customers the most advanced set of sovereignty controls and features available in the cloud.
Customers have always controlled the location of their data with AWS. For example, currently in Europe, customers have the choice to deploy their data into any of eight existing AWS Regions.
“We commit to deliver even more services and features to protect our customers’ data. We further commit to expanding on our existing capabilities to provide even more fine-grained data residency controls and transparency. We will also expand data residency controls for operational data, such as identity and billing information,” said Matt Garman, SVP of AWS Sales, Marketing and Global Services.
Customers are facing an incredible amount of complexity, and over the last 18 months, “many have told us they are concerned that they will have to choose between the full power of AWS and a feature-limited sovereign cloud solution that could hamper their ability to innovate, transform, and grow”,” Garman added during the AWS �Re: Invent 2022′ summit.
Currently, AWS gives customers features and controls to encrypt data, whether in transit, at rest, or in memory.
All AWS services already support encryption, with most also supporting encryption with customer managed keys that are inaccessible to AWS.
“We commit to continue to innovate and invest in additional controls for sovereignty and encryption features so that our customers can encrypt everything everywhere with encryption keys managed inside or outside the AWS Cloud,” said Garman.
The company said it will continue to enhance its range of sovereign and resilient options, allowing customers to sustain operations through disruption or disconnection.
“We commit to continuing to provide the transparency and business flexibility needed to meet evolving privacy and sovereignty laws,” it added.
