Windows hệ thống 2008 has reached over of life, which typically means upgrading khổng lồ a newer version. But hostingvietnam.vns have options beyond updating to lớn a more recent iteration of Windows server, including staying put or migrating khổng lồ the cloud.

If you still have workloads running on Windows vps 2008, you’re not alone. As recently as July 2019, Microsoft executives at the company’s Inspire partner conference estimated that up khổng lồ 60 percent of Windows servers were still running Windows vps or SQL server 2008.

Businesses that have stuck with Windows server 2008 won’t notice the absence of support until February’s Patch Tuesday, as Microsoft released a security update on the last day of support, Jan. 14. The company’s support web pages say it will provide no more patches for the OS, although that’s not strictly true.

Microsoft’s server products begin life with “Mainstream Support,” including security and feature updates. For Windows vps 2008, that ended in 2015, with mainstream support for Windows vps 2008 R2 ending the following year.

Since then, both versions of Windows hệ thống 2008 have been receiving what Microsoft calls “Extended Support,” which includes only security updates. This gives businesses an extra three years or so to pick the right moment to update khổng lồ a newer version of Windows Server.

Embrace & extend

Even now, with the end of Extended Support, Windows vps 2008 isn’t dead. Enterprises that want to hold onto the OS for a little longer can sign up for Microsoft’s Extended Security Update Program and receive fixes for another three years — for an annual fee of around 75 percent of the license price.

Microsoft describes this option of doing nothing but cutting a kiểm tra as a “last resort.” After that, it really is the end.

There is another way to lớn obtain extended security updates, and that is khổng lồ move on-premises Windows hệ thống 2008 workloads to lớn Microsoft’s Azure cloud, running them as-is on a VM or managed instance. For enterprises that pay for its hosting service, Microsoft says it will throw in three years of security updates for free.

Cloud migration

Amazon website Services has another idea: Migrate workloads lớn its cloud instead of Azure, and upgrade khổng lồ a newer version of Windows at the same time. Its End-of-support Migration Program (EMP) for Windows vps offers a way lớn decouple applications from the underlying OS, wrapping them in a compatibility layer that redirects calls to lớn APIs that have changed. The software to bởi that is free, but AWS or its partners will charge a fee to assess & repackage the applications — and, of course, to lớn host them in the AWS cloud.

Enterprises moving on-premises workloads to clouds other than Azure will need to examine their paperwork carefully. Last October, Microsoft changed its rules, requiring customers moving on-premises Windows licenses into certain vendors’ clouds khổng lồ pay additional fees for Software Assurance & mobility rights.

Against these cloud và licensing costs, hostingvietnam.vns will have to weigh the benefits of ditching the old, unreliable hardware their applications were running on.

The upgrade path

Finally, there’s the conventional path khổng lồ consider: upgrading Windows vps 2008 khổng lồ a still-supported version.

This is a multi-step process, the first of which is khổng lồ upgrade to Windows hệ thống 2012. Mainstream support for this has already ended, and extended tư vấn will run only until 2023.

From there, it’s another hop lớn Windows server 2016, which benefits from mainstream support until late 2022, & then one last jump khổng lồ Windows hệ thống 2019 for full support through 2024.

Enterprises running the R2 version of Windows server 2008 can skip a step, moving via 2012 R2 straight to Windows server 2019.

Microsoft’s documentation on this process highlights why so many businesses have decided khổng lồ stick with the older OS, noting that not all vps roles và applications are supported in newer versions, & warning that careful planning of the update process is necessary khổng lồ avoid surprises.

That’s sound advice whether updating, migrating, extending — or doing nothing: only careful evaluation of an enterprise’s own situation can show the right way khổng lồ go.
