CentOS 7 was released on the 7th of July 2014. For many years, it has been the operating system for millions of servers. Last Sunday (30th of June) was the day when, after almost 10 years, CentOS 7 became end-of-life. This means that no (security) updates for CentOS 7 will be released any more, and that servers running CentOS 7 are at risk.
I personally know of quite a few servers that are still running on CentOS 7. Even though the EOL date of CentOS 7 has been known for a very long time, many companies waited till the very last moment to phase out these systems and then missed their target. This is a bad situation to be in. I expect that it won’t be long before vulnerabilities in these systems become public, which then can no longer be patched. Migrating these systems to a new operating system should be top priority for these companies!
