explanation for non-techies**
Imagine you have a car that runs on a specific type of fuel, let's call it "Fuel 1.1." Over time, the gas stations decide to stop selling "Fuel 1.1" because it's not as efficient or safe as the newer "Fuel 1.2." If you don't switch to using "Fuel 1.2" by a certain date, your car won't be able to run because it won't have the fuel it needs.
In the IT world, this is similar to what's happening with the Fabric Platform and the TLS (Transport Layer Security) protocols. TLS is like the fuel for secure connections between your systems and the Fabric Platform. The older version, TLS 1.1, is being phased out, much like the outdated fuel. By July 31, 2025, you need to ensure that all your systems are using TLS 1.2 or later, which is the newer, more secure version.
Just like you would check your car's fuel compatibility, you need to review your systems to ensure they are ready for this change. If any of your systems are still using the older TLS 1.1, it's important to update them to TLS 1.2 or later. This update is crucial to avoid any disruptions in service, similar to how a car would stop running without the right fuel.
Additionally, you should verify that your security settings and policies are aligned with these new requirements. This is akin to making sure your car's engine is tuned to handle the new fuel type. If you have questions or need assistance, there are resources available, such as community experts and support services, to help guide you through this transition.
