On-Premise vs Cloud —
and the New On-Premise.

Cloud welding software runs on a vendor's servers and you reach it through a browser. It is genuinely easy to start with — nothing to install, reachable from anywhere — and for some shops that is enough. The trade-offs are structural, not incidental:

• Your records live on shared infrastructure. Weld data and IP sit on a third party's servers, reachable on the public internet by design — a real consideration for shops that treat their records as sensitive assets.
• Access depends on the vendor. When the service is down, so are your records. When the subscription ends, access can end with it.
• The bill scales with you. Per-seat or usage pricing, often behind a quote, tends to grow with your team and your data — and is hard to fix in advance.
• It stops when the connection does. A browser tool on a public URL cannot capture work in a dead zone or through an internet outage.

Traditional on-premise software solved the ownership problem — your data on your hardware — but it earned on-premise its reputation for being heavy. This is the picture most people still have in their heads, and it is why "on-premise" can sound like a step backwards:

• It became an IT project. Someone had to specify, install, configure and maintain a server — staff or budget most fabrication shops would rather not spend.
• You patched it yourself. Updates, security fixes and monitoring fell on the shop, or on an external contractor billed by the hour.
• Remote access was awkward. Reaching an in-building server from home or the field usually meant opening ports or standing up a VPN — friction, and exposure.
• "On-premise edition" often meant less. Some vendors shipped a cut-down local build and kept the real product in the cloud.

Every one of these is a real reason shops drifted toward cloud. They are also exactly the problems a modern appliance is built to remove.

A modern on-premise appliance keeps what made on-premise worth choosing — your data, physically in your building — and engineers away the burdens that made it painful. This is the generation Elenchon is built on:

• No IT project. It ships as a sealed, containerized appliance that the vendor's own engineers deliver, install and configure on-site. Your only ongoing job is to keep it powered on — there is no server for your team to build or administer.
• You never patch it. Updates and monitoring are applied remotely by the vendor over a secure overlay. The maintenance burden that defined classic on-premise simply isn't yours anymore.
• Remote access without exposure. Authorised staff — and even auditors — reach the appliance from home, mobile data or abroad through a mutually authenticated, post-quantum-safe tunnel, while the appliance opens no inbound ports and stays invisible to the public internet. You get cloud-like reach with none of the cloud exposure.
• Offline-first, so the floor never stops. Capture runs disconnected by design and syncs on reconnect — the opposite of a browser tool that dies with its link.
• The whole platform, not a local edition. Every capability runs on the appliance, with no minimum term and no exit fee. What you build stays yours, and you keep view-only access to your history even if you leave.

The result reframes the debate: you no longer trade ownership for convenience. You keep the data in your building and reach it from anywhere, without running a server or patching anything.

Reduced to the questions that actually decide it:

• Want zero hardware and are comfortable with records on a vendor's infrastructure? Cloud will serve you.
• Want to own your data but remember on-premise as an IT headache? That headache belonged to the old model — the appliance generation removes it.
• Take ownership, predictable cost, security and continuity seriously? A modern on-premise appliance is the strongest answer on every one of those, which is exactly what Elenchon was built to be.
