End of Life (EOL), End of Service Life (EOSL), and End of Support (EOS): Key Differences and Implications

EOL, EOSL, and EOS are terms used to describe the different stages at which a product or service is no longer actively supported or maintained by the manufacturer or supplier. Understanding the differences between these terms can help organizations make informed decisions about their IT infrastructure and plan for the end of life of their products and services.

• End of Life (EOL) refers to the point at which a product or service is no longer manufactured or produced. This can also include the discontinuation of support and maintenance for the product or service.
• End of Service Life (EOSL) refers to the point at which a product or service can no longer be supported or maintained by the manufacturer or supplier. This can include the discontinuation of spare parts, repairs, and updates.
• End of Support (EOS) refers to the point at which a product or service will no longer receive updates, security patches, or technical assistance from the manufacturer or supplier. This can also include the discontinuation of hardware support and warranty coverage.

The key differences between EOL, EOSL, and EOS are as follows: EOL is the end of production, EOSL is the end of support and maintenance, and EOS is the end of software support and updates. EOL is the most final step, and EOSL and EOS are the stages of discontinuing the service. EOSL and EOS may happen after EOL or simultaneously.
