Why a single write-ahead log on S3, speaking POSIX, can collapse all of them into one storage system. - [How to store data safely](https://archil.com/post/how-to-store-data-safely.md) (2026-08-18): Archil is one of the few storage services that actually stores customer data rather than delegating it to S3. Durability math, correlated failure, erasure coding, and copysets -- what it takes to not lose your data. - [Understanding file storage](https://archil.com/post/understanding-file-storage.md) (2026-08-17): Block devices, file systems, and why remote file storage has always been slow. A ground-up look at what a file system actually is, and how Archil makes a shared one fast enough to run git clone on. - [Context that agents understand](https://archil.com/post/context-that-agents-understand.md) (2026-07-06): New Archil integrations for the Vercel AI SDK, eve, Mastra, and LangChain. One function exposes a persistent, shared, compute-enabled filesystem to your agents. - [Be careful which "persistent" disks you trust](https://archil.com/post/be-careful-which-persistent-disks-you-trust.md) (2026-06-19): Not all "persistent disks" are created equal. What it actually means for data to be safe, what your infrastructure provider could be doing behind an fsync, and the question you should be asking before you trust them with a database. - [Agents were built for the $5 VPS](https://archil.com/post/agents-were-built-for-the-5-vps.md) (2026-06-16): Serverless is the 'MCP' of the hosting world. Just like we moved from MCP to file systems, the industry will move from serverless platforms back to the virtual server as the de-facto hosting strategy in the agent era. Here's why. - [Where are the serverless sandboxes?](https://archil.com/post/where-are-the-serverless-sandboxes.md) (2026-06-15): Yesterday, @ankrgyl, the CEO of Braintrust, remarked that it felt like sandboxes were the convergence of servers and serverless. He should be correct here, it is the case that sandboxes kind of feel... - [Launching a million sandboxes per second in constant time](https://archil.com/post/launching-a-million-sandboxes-per-second-in-constant-time.md) (2026-06-12): They say that in the future, everyone will have their own sandbox company for 15 minutes. Let's make that simpler, here's exactly how I built our compute platform to handle millions of sandbox... - [Are Archil's sandboxes as free as Cloudflare egress?](https://archil.com/post/are-archils-sandboxes-as-free-as-cloudflare-egress.md) (2026-06-09): One thing that customers are most surprised by when they move to Archil is that their sandbox costs usually go to $0 by moving to Serverless execution. This is great for them, but also a little... - [The file system is the agent](https://archil.com/post/the-file-system-is-the-agent.md) (2026-06-08): A few weeks ago, we spoke about how the file system is the most important state management primitive of the AI era. As a result, the file system needs to evolve for this new reality. The first way... - [Who will build Vercel for agents?](https://archil.com/post/who-will-build-vercel-for-agents.md) (2026-06-05): This isn't surprising to you, but I believe there's a reason why none of the 'vercel for agents' companies have won yet: none of these technologies have innovated in how to manage stateful... - [Building file system transactions for agents](https://archil.com/post/building-file-system-transactions-for-agents.md) (2026-05-01): There are a lot of reasons why object storage solutions like S3 became so popular for cloud application development in the past 20 years with 'low-cost' and 'ubiquity' being two. I think there's a... - [Should storage be local or remote?](https://archil.com/post/should-storage-be-local-or-remote.md) (2026-04-24): When I started Archil in 2024, I was coming from a world of networked, disaggregated storage products. My primary goal was to build a system for file storage (which has super powers like... - [Is S3 faster than a file system?](https://archil.com/post/is-s3-faster-than-a-file-system.md) (2026-04-23): One of the most interesting things that used to happen to me when I was working at AWS was hearing from customers who told me that they 'preferred to use S3 because it was faster than EFS'. This was... - [Archil raises $11M to connect AI to data](https://archil.com/post/series-a.md) (2026-04-20): We've raised an $11M Series A to connect AI to data — a persistent file system for agent context, with the compute to work on it built in. - [Agents share environments, not data](https://archil.com/post/agents-share-environments-not-data.md) (2026-04-18): Agents today mirror the software development world of the late 2000s before the secrets from Google, Amazon, and Facebook on scaling engineering teams and services became common knowledge. Today,... - [Bash is the SQL for file systems](https://archil.com/post/serverless-execution.md) (2026-04-15): Introducing serverless execution: run bash on Archil file systems directly, without provisioning compute or moving data. Live today in all public AWS regions, and in BYOC deployments on any cloud. - [The file system is the sandbox](https://archil.com/post/the-file-system-is-the-sandbox.md) (2026-04-14): Let's start by thinking about the Ship of Theseus, which asks the question 'if you replace every plank in a ship, at what point does it become a different ship?'. This is kind of hard to answer, but... - [S3 Files: the right product on the wrong foundation](https://archil.com/post/s3-files-deep-dive.md) (2026-04-13): AWS S3 Files lets you mount an S3 bucket as a file system. The idea is right. But building it on NFS creates a cascade of problems — in latency, scalability, and pricing — that no amount of engineering can fix. - [Archil now supports mounting from just-bash](https://archil.com/post/just-bash-support.md) (2026-02-02): Archil now supports just-bash, a new way to interact with your data. - [Why file systems are here to stay](https://archil.com/post/why-file-systems-are-here-to-stay.md) (2026-01-14): The industry has discovered that the file system is a surprisingly effective interface to give AI access to data. Here's why file systems are becoming the universal context layer for AI agents. - [Archil: from a file system to a data company](https://archil.com/post/archil-file-system-to-data-company.md) (2025-06-02): Archil (formerly Regatta Storage) has raised $6.7M to replace legacy cloud storage like EBS with infinite, shareable volumes that instantly connect to S3. - [Introducing Archil](https://archil.com/post/introducing-archil.md) (2025-03-31): Regatta Storage has rebranded as Archil, reflecting our expanded focus beyond storage to comprehensive data management.
