About to be hit by the RHEL6 and Windows 2008 double whammy?
If you're just organizing your Red Hat Enterprise Linux 6 Extended Life (ELS) phase for the end of November don't forget Windows Server 2008 Extended Security (ESU) phase is about to rollover to year 2 in January!
Unlike RHEL6 with WS2008 you'll need to cover all of the base licenses with ESU entitlements, and at 75% of the current list price that can prove to be a very expensive exercise. So if you won't have time to migrate off WS2008 your best option - depending on numbers - is to isolate them, either via host affinity in your virtual farms or by pushing them onto physical servers.
Fortunately Red Hat licensing allows the choice of either physical sockets or virtual machines, so you can mix and match to suit. The tipping point is around 6 VMs, and again you can limit your exposure by applying host affinity rules in your virtual farms. There has been some conjecture as to whether the VM license covers one or two VMs - we are reliable informed that it does indeed cover two.
The bottom line is of course, keep ahead of product lifecycles - it will always be more cost effective from a licensing point of view, but of course often difficult in the business context. The same situation will be upon us soon enough with WS2012 and RHEL7, so time to look ahead, ramp up the urgency, and get migrations on the agenda.
So what do I get and what will it cost?
Firstly - Microsoft:
You'll need to be an Windows Server (for as many servers as need cover) Active Software Assurance (SA) customer. Costs are then dependent on the type of installation:
In Azure: Customers running Windows Server in an Azure Virtual Machine will get Extended Security Updates for no additional charges above the cost of running the virtual machine.
On-premises: Customers with active Software Assurance or subscription licenses can purchase Extended Security Updates for approximately 75% of the on-premises license cost annually.
Hosted environments: Customers who license Windows Server through an authorised SPLA hoster will need to separately purchase Extended Security Updates under an Enterprise or Server and Cloud Enrolment, either directly from Microsoft for approximately 75% of the full on-premises license cost annually or from their Microsoft reseller for use in the hosted environment.
For Red Hat:
You must have already have paid for a Red Hat Enterprise Linux subscription before purchasing the ELS Add-On subscription for it. ELS Add-On is applicable to Standard or Premium subscriptions and can not be applied to self-support subscriptions. Note that ELS should be purchased prior to the start date of the ELS period (December 1, 2020 for RHEL 6), otherwise the ELS Add-On subscription will be back-dated to the start date.
The cost on the Red Hat store is US$250 for Standard or US$775 for Data Center, so around AU$500 (2x VMs) to AU$1500 (Socket Pair).
