Editing On-Premise vs. SaaS

SaaS ( Software as a Service )
🧩 Main Idea
In the past, you had to download and install software to use it. With SaaS, the software is hosted in the cloud, and you can use it through a web browser. You don’t buy the software — you subscribe to it (monthly or yearly).
☁️ How It Works
* 		The software is stored on remote servers (like Amazon AWS or Google Cloud).
* 		Users simply log in online to access it.
* 		All updates, data backups, and security are handled by the service provider.
💡 Common Examples
* 		Google Docs — create and edit documents online.
* 		Zoom — video meetings without complex setup.
* 		Dropbox / Google Drive — store and share files in the cloud.
* 		Slack, Notion, Canva — collaboration and productivity tools.
On-Premise
🧩 Main Idea
In the on-premise model, the organization:
* 		Buys or licenses the software.
* 		Installs it on their own computers or local servers.
* 		Maintains and updates it themselves.
So, everything — data, updates, and security — is managed inside the company’s infrastructure, not by an external cloud provider.
⚙️ How It Works
* 		Software is installed on the company’s machines.
* 		The company’s IT team maintains and updates it.
* 		Users can access it only within the organization’s network.
🏢 Example
* 		Microsoft Word (offline) — you buy and install it on your computer.
* 		ERP systems (like SAP, Oracle installed locally) — run on the company’s internal servers.
🕰️ Short History
* 		In the 1960s, the basic idea existed in the form of time-sharing on mainframe computers, where multiple users shared the same software resources.
* 		In the 1990s, as the internet became more widespread, it became possible to deliver software through web browsers.
* 		In 1999, Salesforce was founded — this marked the true beginning of the modern SaaS era. They offered CRM software through the internet using a subscription model.
* 		After 2000, major tech companies like Google (Google Apps), Amazon (AWS), and Microsoft (Office 365) expanded the SaaS concept globally.
* 		By the 2010s, SaaS had become the dominant software delivery model used by most businesses and individuals.
