With Windows Server 2008 End of Life happening soon, this means the extended support will also finish.
On January 14th 2020, Microsoft will end all support for Windows Server 2008.
Whilst the systems will continue to work, the infrastructure will not be supported which means it will become vulnerable to cyber-attacks and risks of data loss over time.
Options could include migrating to Microsoft Azure, a cloud computing service or upgrading to a later version of Windows Server including 2012, 2016 or 2019, depending on your requirements.
Hopefully, your IT support company has advised you of this important date if you are currently using Windows Server 2008 but if not speak with them to advise you about your options in particularly what is best for your business requirements.
