MinIO AIStor Sets New Standard for AI and Data-Intensive Workloads with Industry-First AWS S3 Express API Support
Enterprise object storage with built-in replication brings S3 Express API performance to the entire data lakehouse, at no extra cost
REDWOOD CITY, Calif., May 29, 2025 /CNW/ -- MinIO, the leader in high-performance object storage for the exabyte AI era, today announced AIStor support for Amazon's S3 Express API, a streamlined version of the general-purpose S3 API designed to deliver maximum performance for AI and data-intensive analytics workloads. MinIO AIStor is the first and only AI data storage platform to adopt Amazon's S3 Express API and enable organizations to put all of their analytical and AI data, not just a subset, in "express mode" at no extra cost.
Introduced by AWS in 2023 and delivered via the Amazon S3 Express One Zone storage class, the Amazon S3 Express API has defined a new industry standard for high performance and developer-friendly AI and analytics storage, delivering 10x faster performance compared to the S3 Standard storage class. But, in AWS, the enhanced performance of AWS S3 Express One Zone comes at over five times the cost of S3 Standard to store data and doesn't come with data protection and replication capabilities. Consequently, to use it safely, customers must save a durable copy of their data in S3 standard and copy data that requires high speed access into S3 Express One Zone.
With this release, MinIO is democratizing access to and use of this powerful API for all data processing needs by coupling its dramatic performance advantages with full active/passive, disaster recovery (DR), and batch replication support, all at no extra cost. Enterprises can continue leveraging the general purpose S3 API for raw source data requiring versioning and immutability before any processing, but can now leverage the high performance S3 Express API for all other downstream workloads and derived data sets, especially, but not limited to, high intensity data processing. This includes the majority of data lakehouse analytics with Apache Spark and Iceberg, AI data pre-processing, and AI model training and inference.
"Until now, use of S3 Express has typically been reserved for data that requires high speed access at the expense of enterprise features like replication and lifecycle management, due to its cost premium over S3 Standard," said Garima Kapoor, co-founder and co-CEO, MinIO. "We're changing that because we believe it can and should become the standard API for all analytical data and AI workloads. With the AIStor S3 Express API, pricing remains the same so enterprises can now put all of their analytical and AI data, not just a subset, in 'express mode.' This is drawing tremendous excitement from customers."
"In most lakehouse environments, versioning is already handled by table formats like Apache Iceberg, which provide atomic operations at the file or table level," said Sanjeev Mohan, principal analyst at SanjMo. "But when versioning is also enabled at the storage layer, it can create unnecessary duplication and complexity. Removing it from the storage layer simplifies the backend architecture, lowers CPU usage on storage servers, and helps prevent accidental storage growth and rising costs."
AIStor's S3 Express API support comes at no extra cost, without any request charges for GETs, PUTs and LISTs, and with key data protection and replication capabilities so it can be used for all enterprise analytical and AI data. Key features and benefits of the AIStor S3 Express API include:
Accelerated PUT and LIST operations: delivers up to 20% faster PUT operations, lowering CPU utilization, and up to 447% faster time-to-first-byte (TTFB) LIST operations relative to AIStor general purpose S3 API. This means faster training, faster analytics, and better infrastructure utilization.
New atomic, exclusive append operations: enables direct and safe object modification, eliminating multi-step update workflows. For example, media-broadcasting applications which add new video segments to video files can do so as they are transcoded and immediately streamed to viewers.
Full active/passive, disaster recovery (DR), and batch replication support: provides full performance benefits of the S3 Express API without loss of business continuity and disaster recovery (BC/DR). Synchronous replication means no data loss in the event of an outage and asynchronous replication enables data protection across the globe.
Streamlined and simplified API behavior: eliminates redundancies and implements simplifications and guardrails to improve the developer experience as well as application resiliency, predictability and security.
As the first and only on-premises and private cloud AI storage platform to adopt Amazon's S3 Express API, MinIO is reinforcing its ongoing commitment to providing full and complete S3 API compatibility.

Why Is Everyone Talking About Coupang's Stock?
Coupang (NYSE: CPNG) may not be a well-known company in the U.S., but it has certainly captured the hearts of consumers in South Korea, growing over the years to become the top e-commerce company in its home market. Coupang's solid performance has captured the attention of sharp-eyed investors, which explains its respectable 25% increase in stock price in the last 12 months (as of this writing). Where to invest $1,000 right now? Our analyst team just revealed what they believe are the 10 best stocks to buy right now. Continue » This article will delve deeper into the company and explore why investors are excited about it. The Amazon of South Korea and beyond Amazon has arguably been the most successful e-commerce company over the last two decades, leading to numerous clones attempting to replicate its business model in their respective markets. Most either don't perform well or fail outright, except for a handful, such as in China and Coupang in South Korea. Inspired by Amazon's customer obsession, Coupang strives to please its customers continually. One way is to provide a wide selection of products to customers, delivered at breathtaking speeds via its extensive in-house warehouse and logistics infrastructure. For instance, consumers can order fresh groceries and millions of other general merchandise items by midnight and receive products by 7 a.m. the next morning. If customers are unhappy with the products, they can tap a button on the app and leave the item outside their door for pickup -- refunds will be processed immediately after pickup. But that's just one part of the story. Coupang's efforts to delight its users have expanded far beyond their roots into other areas, including food delivery, online streaming, and services such as free appliance and furniture installations. Customers are eligible for all these perks for free if they join the Wow membership program. Unsurprisingly, customers love this approach, which explains Coupang's leading market share of 25% in South Korea. Coupang's success in South Korea has also prompted the company to expand into new geographies, such as Taiwan, and new business segments via the acquisition of Farfetch. While these new business additions will take time to bear fruit, they will open up new growth avenues for the e-commerce company. Coupang is executing well lately Coupang is also delivering solid growth. For the year ended Dec. 31, revenue surged by 24% (or 29% on an currency-neutral basis) to $30.3 billion on the back of growth in its e-commerce business and the acquisition of Farfetch. Coupang's growth continued into 2025, with revenue growing at 11% (or 21% on an currency-neutral basis ) to $7.9 billion. Top-line growth is just one part of the story. Coupang has gradually improved its margins over time, with adjusted earnings before interest, taxes, depreciation, and amortization (EBITDA) margins improving from 3.9% to 4.8% in the last five quarters. The tech company targets adjusted EBITDA margins to exceed 10% in the long run, suggesting that there is still considerable room for improvement. In short, while Coupang is already generating tens of billions in revenue, it is well-positioned to sustain its growth momentum, leveraging its world-class infrastructure, vast customer base, and customer-obsessed culture. Coupang authorized a $1 billion share buyback plan Coupang's recent share buyback plan is a significant milestone for several reasons. One, it suggests that Coupang has evolved from a high-growth, loss-making company to one that's growing more sustainably and responsibly. To the extent that it can return excess cash to shareholders, such a move also signals the company's confidence in its future, suggesting that management may view the shares as undervalued compared to the company's prospects. Additionally, with ample cash on its balance sheet ($6.1 billion in cash and cash equivalents, as of the time of writing), management's share buyback plan demonstrates its discipline in capital allocation, which complements its other investments in growth and innovation. It also suggests that management has a clear strategy for capital allocation, which is likely to enhance long-term shareholder value. What it means for investors Coupang is a rare example of a successful Amazon clone that has achieved excellent outcomes. While continuing to execute its expansion strategy, Coupang is also on track to return excess cash to shareholders through share buybacks. Investors seeking to diversify their stock holdings beyond the U.S. may want to keep this company under their radar. Don't miss this second chance at a potentially lucrative opportunity Ever feel like you missed the boat in buying the most successful stocks? Then you'll want to hear this. On rare occasions, our expert team of analysts issues a 'Double Down' stock recommendation for companies that they think are about to pop. If you're worried you've already missed your chance to invest, now is the best time to buy before it's too late. And the numbers speak for themselves: Nvidia: if you invested $1,000 when we doubled down in 2009, you'd have $363,030!* Apple: if you invested $1,000 when we doubled down in 2008, you'd have $38,088!* Netflix: if you invested $1,000 when we doubled down in 2004, you'd have $674,395!* Right now, we're issuing 'Double Down' alerts for three incredible companies, available when you join Stock Advisor, and there may not be another chance like this anytime soon.

2 Artificial Intelligence (AI) Stocks to Buy Before They Soar to $3 Trillion, According to Certain Wall Street Analysts
Shares of Amazon (NASDAQ: AMZN) and Alphabet (NASDAQ: GOOGL)(NASDAQ: GOOG) have fallen a few percentage points year to date despite a 2% return in the benchmark S&P 500 (SNPINDEX: ^GSPC). But certain Wall Street analysts anticipate substantial gains in those stocks in the next 12 months, as detailed below: Ivan Feinseth at Tigress Financial has set Amazon with a target price of $305 per share. That implies 44% upside from its current share price of $212. It also implies a market value of $3.2 trillion. Paul Chew at Phillip Securities has set Alphabet with a target price of $250 per share. That implies 45% upside from its current share price of $172. It also implies a market value of $3 trillion. Here's what investors should know about Amazon and Alphabet. Amazon: 44% implied upside The investment thesis for Amazon centers on its strong position in three growing markets. It runs the most popular online marketplace outside of China, powering nearly 41% of retail e-commerce sales in the United States. Amazon is also the largest retail media company, collecting nearly 77% of domestic-retail ad spending and 40% of global-retail ad spending. Finally, Amazon Web Services (AWS) is the largest public cloud, holding 29% market share in infrastructure and platform services. With more customers and partners than any other cloud platform, AWS is particularly well positioned to capitalize on growing demand for artificial intelligence (AI) infrastructure. The company has leaned into that opportunity by developing custom chips for training and inference. Importantly, Amazon is also using AI across its retail business to improve productivity and efficiency. CEO Andy Jassy says the company is developing about 1,000 generative AI tools to make warehouse robots smarter, improve inventory allocation, and optimize delivery routes. Those innovations, coupled with the ongoing restructuring of its logistics network, should improve retail margins in the coming years. As a caveat, Amazon may struggle with tariffs. Morgan Stanley estimates 60% of sellers on the marketplace have some exposure to China, and Chinese sellers represent an important source of advertising revenue. Nevertheless, Andy Jassy believes its diversified seller base will let the company "weather challenging conditions better than others." Wall Street expects Amazon's earnings to increase at 10% annually through 2026. That makes the current valuation of 34 times earnings look expensive. But analysts have often missed the mark in the past. Amazon beat the consensus earnings estimate by an average of 21% in the last six quarters. Assuming that trend continues, the current stock price is quite reasonable. Here's the takeaway: I'm not convinced Amazon stock will return 44% in the next year, but I still think patient investors should own a position, and now is a reasonable time to buy a few shares. Alphabet: 45% implied upside The investment thesis for Alphabet centers on large opportunities in digital advertising and cloud services. Namely, Alphabet is the largest ad tech company on the planet, and digital ad spending is forecast to grow at 15% annually through 2030. While Alphabet has been losing market share for years, it still has a profound ability to engage internet users with platforms like Chrome, Google Search, and YouTube. Also, while internet search is undoubtedly moving toward AI tools like ChatGPT and Perplexity, Alphabet is successfully leaning into that trend. Generative AI overviews in Google Search are driving higher usage and satisfaction. And its generative AI application Gemini was the second-most downloaded AI chatbot behind ChatGPT last year, according to Sensor Tower. Google is the third-largest public cloud. It accounted for 12% of infrastructure and platform-services spending in the first quarter, up a percentage point from the prior year. Meanwhile, Amazon and Microsoft lost share. Google may continue to outpace its peers due to strength in large language models and AI infrastructure, two categories where Forrester Research has recognized the company as a leader. Importantly, Alphabet has a third major opportunity in autonomous driving technology. That industry is far less developed than digital advertising and cloud computing, but the global autonomous ride-sharing market could top $2 trillion over the next decade, according to Evercore. Alphabet's Waymo is an early leader. It currently provides 250,000 driverless rides per week across four U.S. cities, up fivefold from last year. As a caveat, Alphabet faces a possible breakup depending on the outcome of two antitrust lawsuits that have progressed to the remediation phase. A federal judge will propose fixes for its illegal internet search monopoly in August, and another federal judge will rule on its ad tech monopoly at a future date. Most analysts think the probability of a forced breakup is slim, but the odds are not zero. With that in mind, Wall Street estimates Alphabet's adjusted earnings will increase at 7% annually through 2026. That makes the current valuation of 19 times sales look somewhat expensive. But Alphabet beat the consensus estimate by an average of 14% during the last six quarters. The current valuation would be reasonable if that trend continues. Here's the takeaway: Alphabet stock could return 45% in the next year if the judges issue favorable rulings in the antitrust cases. But the stock could also decline sharply if either judge orders a breakup. Investors can buy a small position today, but I would wait for more clarity before taking a large stake.

Photo by NICK PROCAYLO / 10108212A Online retail giant Amazon has made a gigantic bet — the size of 9½ Canadian Football League fields — on its B.C. logistics chain with a new warehouse in Pitt Meadows that will serve as a hub for distribution operations in the Lower Mainland.

Approaching the centre's glass-fronted administration building, the warehouse looks like a blocks-long great wall that stretches out almost to the edge of a person's view. Workers at Amazon's new warehouse in Pitt Meadows that will serve as a hub for distribution operations in the Lower Mainland. Photo by NICK PROCAYLO / 10108212A 'Fun fact, this is almost twice the size of Rogers Arena in the downtown,' said Surakesh Kumar Aruchamy, Amazon's regional director of operations at the building's official opening. 'And the building's cube is more than 35 Olympic sized swimming pools, that's how much space we have.' Stay on top of the latest real estate news and home design trends.

It's staffed at the outset by a crew of 100, mostly associates, who are receiving truckloads of new inventory and stacking it on the rows of tightly spaced shelving that stretch half the length of the building. Aruchamy said about half the space is being used now, but is slowly filling up. On a visit Friday morning, the quiet within the cavernous space was sporadically punctuated by horn honks on the battery-powered self pickers — stacking forklifts that lift up cage platforms for workers to put inventory on shelves. The new warehouse, identified as YXX1 in Amazon's system, is the first storage and distribution centre in B.C. in a location picked, in part, based on the company's objective to 'be closer to customers,' Aruchamy said. This advertisement has not loaded yet, but your article continues below. 'British Columbia is one of our biggest markets within Canada and we want to make things faster for customers, get closer to the customers,' he added. And 'the Lower Mainland is a very strategic location.' Narrowing down the specific location is a formula that involves finding a site that is close enough to the customer fulfilment centres in Tsawwassen, Delta, Richmond and New Westminster that is also big enough to hold the inventory it needs to, Aruchamy said. 'There are multiple factors which goes into deciding how big a facility needs to be,' Aruchamy said. 'We call it working backwards.' Amazon's new 825,000 square foot storage and distribution fulfilment centre, YXX1 in Pitt Meadows. Photo by NICK PROCAYLO / PNG That starts with estimating how much inventory they need for a population the size of the Lower Mainland to hit their targets for delivery times. This advertisement has not loaded yet, but your article continues below. 'We call it one-day speed,' Aruchamy said. 'What percentage of our orders get delivered within the same day and within one day or two days.' Then it's a matter of building a warehouse that can accommodate the amount of shelving, the number of forklifts and truck bays to house and move around that estimated stockpile of inventory. During Friday's tour, workers were busy taking merchandise off trucks, running them along conveyors to be scanned into inventory, then placing them in the cages that pickers move to shelves for storage. The facility fits in at the front end of Amazon's logistics chain — no customer orders are picked and packed in Pitt Meadows. Instead, on the other side of the loading dock, workers are reversing the process — taking merchandise requested by its four customer fulfilment centres, sorting those orders, scanning them again and putting them back on trucks. Large video displays indicate one truck is heading to Richmond and one is destined for Edmonton. This advertisement has not loaded yet, but your article continues below. Amazon's new 825,000 square foot storage and distribution fulfilment centre in Pitt Meadows. Photo by NICK PROCAYLO / 10108212A The Pitt Meadows site is almost adjacent to an existing Amazon delivery station, one of the facilities at the last step of its logistics chain. 'So I think we have a good infrastructure available (in Pitt Meadows),' Aruchamy said. 'Sometimes we have a bigger facility, but we take the best possible real estate possible,' he added. 'Then also it has to work out for us financially because we want to deliver products faster, but also not cost a lot.' The timing of its opening might be awkward due to cross-border trade tensions. About 55 per cent of Canadians polled by Leger Marketing in a survey in March declared they would cut back on orders from U.S. headquartered Amazon as a protest over threatened U.S. tariffs, President Donald Trump's threats to Canadian sovereignty and Amazon founder Jeff Bezos' apparent closeness with Trump. This advertisement has not loaded yet, but your article continues below. Aruchamy couldn't comment on the polling results, or on Amazon's Canadian sales performance, but emphasized that the centre represents a substantial investment by Amazon Canada. 'Small businesses in Canada sell through us, we sell a lot of made in Canada products and we do make a big impact (on) local economics,' Aruchamy said. Pitt Meadows Mayor Nicole MacDonald welcomed Amazon's investment in the facility, and as a new corporate sponsor for community events. 'What we really want to see is jobs and skilled growth,' MacDonald said. 'We're really excited to see Amazon investing back in the community.' depenner@ Amazon's expanding presence in Metro Vancouver Canada's biggest online retailer has a substantial footprint in the Lower Mainland with 12 locations ranging from distribution to fulfilment and delivery stations as follows: Storage and distribution fulfilment YXX1, 825,000 square feet, Pitt Meadows Customer fulfilment centres YXX2, 440,000 square feet, Richmond YVR2, 190,000 square feet, Delta YVR3, 580,000 square feet, New Westminster YVR 4, 450,000 square feet, Tsawwassen Sorting centres Langley AMXL Delivery stations Langley Delivery stations Burnaby (2), Delta, Langley, Pitt Meadows Source: Amazon Read More Vancouver Canucks Vancouver Canucks Sports News Business
