When they deploy Server , with its native hypervisor and built-in virtualization, they set up a lot of virtual machines for old WS workloads. Say you have an old Server machine running file and print services, or a low-use database. A modern server can run that in a VM with little effort. Q: When does extended support end for Microsoft Server ? Microsoft added some time to mainstream support, lengthening that period to January 15, before moving to extended support. Extended support lasts for 5 years, so that would mean extended support for MS should continue to January 15, Microsoft has posted a full list of end-of-life dates.
Well, you can go to a cloud provider like IBM Softlayer or Amazon, but that would mean putting everything in the public cloud. The other choice is Linux. That would depend entirely on what you are doing on the WS boxes. If it's file and print or simple database, you can do it fairly easily. If you are using a highly vertical Windows app not found on Linux, things become more challenging.
You ability to move will depend on the degree of Windows apps you use and if there are Linux equivalents. If you have a lot of home grown apps, you will have a real challenge ahead of you. Q: Will bit apps work on Server ? WoW64 is still there to run bit apps but they will be severely limited in what they can do. Clustering, for example, is gone, and they won't have access to many services. Q: After a migration from Windows Server to , what are the main day- to-day differences that the OS engineer would see?
Well, Server has Hyper-V, albeit an older version. Assuming you used it on bit hardware with lots of memory, then you can virtualize many of your old, underutilized WS servers onto less hardware. Server is a bit OS while Server is bit. So that's a lot more room for databases and web servers, the ability to handle many more users, etc. Q: When choosing an option for migrating off Windows Server , is there a good reason to go with Windows Server instead of Server or Azure?
The most common reason is consistency. Server was a huge leap and it might take your admins a little while to learn it, so sticking with Server if you already have it is the least disruptive solution. Server has five more years of support so you can run it for a while without concern.
Q: Does Windows Server have lower overhead requirements than Server ? No they have the same basic overhead requirements for a minimal install. The difference is Windows Server scales way, way up, far more than Your life will be a lot easier than someone moving a custom app, that's for sure.
Microsoft has migration tools for old versions of SQL Server to new. There's some complexity in that you have to "demote" the old version, say, SQL Server , and "promote" the new version. This way your data all goes through the new version. That all involves deploying the new SQL Server, which migrates over your data and apps.
The good news is it's all done inside SQL Server itself. Q: How much expertise is required to do a hopefully simple server migration?
It depends on the apps being used on that server. Server is a fairly comprehensive OS. You're talking about an operating system with virtualization and the cloud built into the design and the PowerShell often referred to as an OS within an OS.
Blacklisting is the method used in antivirus programs, and since blacklisting relies on knowing what the badware is in the first place, it's why your antivirus program updates two or three times a day and is still often behind the bad guys.
Application whitelisting is a very effective method for application control because only the permitted apps can run. By ensuring only trusted software is allowed to run on the server, application whitelisting will lock out zero-day exploits and other malware. However, McMullin notes it can be a problem is the app whitelisting if done by IP addresses and you have a mobile force, since IP addresses will change as they move.
A cloud backup service requires no hardware to deploy. You can sign up with a provider and start uploading in five minutes and you have a sizable number to choose from. But you better shop around. Amazon S3 backup costs just three cents for 1TB per month. Back in its day, Windows Server handled security issues, but security has since moved out of the OS layer and into discrete appliances, said McMullin.
So that would mean the security workload is divorced from the server. The server would still have security functions to perform but the heavy lifting would be done by an external device," he said. But Denworth notes that these are high-end systems, and "the cost there is arguably in excess of adequate security wrapped around an up-to-date Microsoft environment. At this point, there should be plenty of experienced consultants who can help with the migration, but make sure to check their experience at this.
Microsoft is abandoning the OS but not the people who use it. It has prepared an entire site for Windows Server End of Service , all of which is dedicated to helping you plan your migration. Microsoft lays this out in a four-step migration process, which involves:. The site has a Microsoft Assessment and Planning toolkit you can download, which works with System Center to examine your infrastructure and identify all of the servers and apps running on them. Assess: Now you have a list of servers and apps, it's time to categorize your apps and workloads by type, importance and complexity.
This could mean having to rearchitect your infrastructure around Windows Server and System Center , which have changed radically since Server Target: This is where you the destination for each application and workload.
Because of the variety of apps and workloads, Microsoft offers a number of free software trials to test out your apps and workloads. They include:. All come with 30 day free trials. Use those 30 days to work on compatibility with all the apps, and make sure that when it's in your test environment that everything is stable and meets your needs," said Tsai.
Migrate: This is where you build a migration plan, either to do on your own or with a partner. AppZero is probably the best-known of the Server migration consultancies and has a working agreement with Microsoft. Microsoft offers a Migration Planning Assistant which covers all four steps and has official training courses to help you with the migration. Microsoft Virtual Academy: A massive collection of free study resources from Microsoft MVPs and other experts, including videos, slide decks and self-assessments.
There are whole sections on migrating to Windows Server and Azure. Windows Server Roles Migration Process: This is a very large printable poster that you can stick on a wall and use it to visualize and track the whole process. Microsoft Deployment Toolkit: This is a collection of processes and practices, assistance tools and guidance for automating new desktop and server deployments.

The biggest risk is the lack of availability of security patches. OSes with substantial user bases generally become good targets for hackers, especially when they remain unpatched. That, combined with the projected prevalence of Windows Server VMs that will persist after the support period ends, suggests many organizations will be open to significant security risk.
But before you dive into that process, the first step is to assess the scope of impact in your environment. Our mission at CloudPhysics is to discover discover hidden operational hazards. Clearly the analysis indicates that Windows Server is a potential hazard for many, and CloudPhysics wants to help you protect your organization from harm. View Next Post. Close Search.

Looking for something? One in every five Windows server VMs runs Microsoft Windows Server , and thus will be impacted by the end of support life on July Windows VM share is declining and, given the current rate of decline, will reach a statistically insignificant level in the first half of about three years after the support July EOL date. CloudPhysics does not have historical data prior to , but our backward estimates indicate that the total number of bit VMs surpassed the total number of bit VMs in However, bit VMs still persist and, given the current trend, will not reach statistically insignificant levels until the first half of
