A server is defined as a computer or computer program which manages access to a centralised resource or service in a network.Severs work as part of the client-server model, a model which denotes the serving of data for clients.This reflects the purpose of a server which is to share data, distribute work and share resources.There are a number of ways in which a server can be used, with some servers committed to specific, or dedicated, task.For example, an Application Server hosts web apps so that network users can run and use them without needing to install a copy of the computer programme on their computers.When it comes to operating systems, the dominant operating systems seen on the internet include Linux, FreeBSD and Windows Server - mainly UNIX-like open source distributions.
Citrix has unified its networking products and made big additions to its virtualisation stack.The upshot of this is Citrix users in big Windows shops can now point XenServer at shared storage managed by Windows Server.Which should help users to make the most of storage assets.This release won't hurt that strategy and may give comfort to those hoping to continue using XenServer for other stuff, plus the beginning of a direction on containers.The mantra, as is the case across the industry, is that in these cloudy times we all need to be able to create networks that span our own bit barns and public clouds.Citrix grew in its most recently-reported quarter, a result felt to represent a slightly-unexpected turnaround after years of confused strategy and red ink.
Your life in their handsA US Government Accounting Office GAO report has highlighted the parlous state of Uncle Sam's IT infrastructure.Meanwhile, the Treasury Department is calculating tax returns on a 56-year-old IBM mainframe using programs written in assembly code; it says it has no plans to update its systems."Federal legacy IT investments are becoming increasingly obsolete: many use outdated software languages and hardware parts that are unsupported," the report PDF states."Federal IT investments have too frequently failed or incurred cost overruns and schedule slippages while contributing little to mission-related outcomes.Some Department of Commerce weather alert systems use Fortran and the core network is running Windows Server 2003, which is no longer supported by Microsoft.Several of the systems reviewed by the GAO are scheduled for replacement – the US military will have its nuclear control and targeting systems running on a more modern server by 2020, for example – but plenty of departments reported no plans to upgrade.

VMware is warning administrators to steer clear of an official update for Windows 7 and Server 2008 – after the patch was found to be incompatible with some virtual machines.The virtualization house says that VMs using VMXNet3 virtual NICs are having networking problems after installing the Windows 7 rollup update.VMs running Windows Server 2008 R2 SP1 are seeing similar problems, prompting VMware to recommend that anyone running either OS in their VMs on VMware vSphere should avoid installing the Microsoft rollup until a fix can be worked out."VMware is aware of this issue and we are actively investigating the root causes and possible fixes," the VMware blog says.Microsoft released the Windows 7 rollups last month in an attempt to simplify the process of getting updates for new installations.Designed to be used with either new PCs or install media, the rollup gives Windows 7 all previous updates rather than requiring the new machines to download and install hundreds of patches.
This makes the VTL less appealing than in the past lately also visible in EMC's financial results .You can buy ready-to-run appliances or build them starting from scratch with OpenSolaris/Illumos, Ubuntu and maybe other OSes .Scalability is no longer an issue and the storage repository can do more than backups only – much more.Some new startups, like Cohesity for example, have totally redefined the concept of secondary storage and data protection.They simply no longer make any sense, but please take this comment with a grain of salt, as I ve never been fond of VTLs when I was a Sun Microsystems VAR, I was the greatest fan of the Sun Fire x4500 and they always served like the best of the VTLs for my customers.On the other hand, startups like Cohesity have coined the term Hyper-converged Secondary Storage.
Microsoft has issued fixes to its last round of Windows Server Management Pack fixes, but is asking you to help it understand if the new fixes fix the messes the last fixes created.Redmond now says the fixes in that release caused nine new problems, namely:Disks in a cluster resource group in a failover cluster were not discovered as either logical disks or cluster disks, as the case may be.Disk free space monitoring did not work on Quorum disks in failover clusters.Hyper-V servers in a Windows Server 2012 R2 cluster discovered an additional disk with no properties and with name Microsoft.Windows.Server.6.2.LogicalDisk .So in its notification of the new fixes, it suggests users act as follows:"Please try out these management packs and let us know if the issues are indeed solved.Yes, we know that Windows Server is a very complex product that can be deployed on practically infinite combinations of hardware, with or without good drivers.
Developers can now run Hyper-V Containers easily with the latest betaA Surface Pro 3 running Windows 10 Credit: Blair Hanley FrankMicrosoft has released a new beta build of Windows 10 aimed at enhancing various aspects of the operating system, including support for the LastPass extension in the Edge browser, as the company hurtles toward releasing a major update in the coming months.Build 14361, released Wednesday, includes updated icons, the LastPass password manager extension for Microsoft Edge, and support for running Docker containers natively on Windows.The new build brings the LastPass extension to Microsoft Edge, which lets users of the popular password management service have easy access to their saved passwords.People can set up a container -- basically a simplified operating system environment for use with a particular application -- that runs the Windows Server 2016 Technical Preview 5 Nano Server on their PC.Large amounts of interface text don't get rendered in French, and instead fall back to English.That's par for the course for the Windows release Fast ring, which includes builds that can feature major bugs affecting how people are able to use their devices.
Microsoft has released another preview version of Windows 10 to Insiders testing on the Fast Ring, with the big Anniversary Update just around the corner.Naturally enough, there's a load of bug fixes, as squashing bugs is a priority right now to smooth things over for said Anniversary Update with a June 'bug bash' kicking off next week .But the new features are doubtless what you want to hear about, and Microsoft has introduced another fresh extension for the Edge web browser, this one being security related: you can now download LastPass, an extension for the popular password manager.Windows 10 now also supports Hyper-V Containers, allowing developers to create and run containers which use the Windows Server 2016 Technical Preview 5 Nano Server container OS image.With the Settings app, again interface tweaks have been made, such as adjusting the text size to be more readable and adding a splash of colour to highlight which Settings tab you've selected.Some Windows 10 icons have also been changed for the better, hopefully and Redmond has implemented some important minor fixes, including smoothing over a problem which caused sites like YouTube to fall over in both Edge and Internet Explorer.
Windows Insiders can now see how containers work with Windows 10 ahead of the Anniversary Update this summerMembers of the Windows Insider early-access program can finally take one of the most highly anticipated features to be included in this summer s Windows 10 Anniversary Update: Hyper-V Containers.You can now use Docker natively on Windows 10 with Hyper-V Containers, to build, ship and run containers utilizing the Windows Server 2016 Technical Preview 5 Nano Server container OS image, Dona Sarkar, the new head of the Windows Insider program, announced in a June 8 blog post.A new version of the Docker engine for Windows has also been made available that extends the support of containers while also improving the DockerFile syntax and getting started experience for users, continued Sarkar.Investors are interested in containers because they represent the future of all computing although it s still relatively early days for the technology, notedeWEEK s Sean Michael Kerner in his recent analysis of VC investments in container vendors.On Surface Books, for example, the Windows Ink ruler now spans the entire display when it is turned diagonally.The new Blu-ray icon is more consistent with other drive icons, and the new networking icon in the Quick Action bar does away with the generic globe visual of the past.
Critical fixes for Office, Internet Explorer, and Windows DNS Server highlight this month's edition of Patch Update Tuesday.The Redmond Windows slinger has kicked out 16 bulletins this month, five rated as "critical" and the remaining 11 considered "important" risks.The fix includes remote code execution flaws exploited through malicious web pages.Like the IE flaws, the Edge vulnerabilities would allow remote code execution simply by viewing a web page on the Edge browser.MS16-077 patches two vulnerabilities in the Windows Web Proxy Auto-Discovery that could allow elevation of privilege when a system attempts to target a new proxy.MS16-079 addresses four elevation of privilege and information disclosure vulnerabilities in Outlook Web Access for Windows.
The platform can collect up to one million events per second, and stores data up to a year.Robbins also said that no other company, "from global giants to inspired start-ups", have yet managed to launch such a platform that is "comprehensive, easy-to-use or scalable to the dimensions required by the modern data centre".Billions of flows are searchable in less than a second using Tetration's forensics search engine and user interface.In the first Tetration release set for July 2016, software sensors will support Linux and Windows server hosts, while hardware sensors are embedded in the ASICs of Cisco Nexus 9200-X and Nexus 9300-EX network switches to collect flow data at line rate from all the ports.Speaking to CBR, Bijlsma said: "This platform ships as an appliance, and since it is going to be the place that stores all communication flows from all over the data centre, a tremendous amount of focus has been given on hardening the platform."There is no way to get the wrong data that is stored on the disk unless you are going through the proper analytics search engines."
Microsoft today is announcing new capabilities for running applications in containers — an alternative to more traditional virtual machines — both on its Azure public cloud and in companies on-premises data centers.Rather than simply drop the news in a blog post, today Mark Russinovich, Azure s chief technology officer, is taking the stage at container startup Docker s Dockercon conference in Seattle to demonstrate some of the new features.First, the Docker Datacenter software is coming to the Azure Marketplace, and so Russinovich is showing an example of a container cluster provisioned by Docker Datacenter that s running on top of infrastructure in Azure and private-cloud infrastructure managed by Microsoft s Azure Stack software.All that it takes is just a few clicks, Russinovich told VentureBeat in an interview before his appearance at Dockercon.Azure Resource Manager templates are the key to the ease of the deployment.Russinovich is also showing the next step in Microsoft s journey to bring its SQL Server database software beyond Windows.In March the company said it would bring SQL Server to Linux, and so today, naturally, he ll show SQL Server on Linux running inside a container that s managed by Docker Datacenter — in a virtual machine on Azure Stack.Linux containers in general, and open source Docker specifically, have been very relevant to Microsoft, as it sells Windows Server server virtualization software that runs and manages applications in virtual machines, and the company also rents out compute infrastructure in Azure.In the past three years many developers have embraced the technology, and so Microsoft has taken many steps to embrace it too, rather than shake its head and hold its nose.On the cloud side, it launched the Azure Container Service.On premises, Microsoft has introduced Hyper-V Containers in Windows Server.In just a year s time we ve gone from 1 in 4 of our Azure virtual machines running Linux, to nearly 1 in 3, Russinovich wrote in his blog post on today s news.
Microsoft's Scott Hanselman demonstrates .NET Core at Red Hat's DevNation eventMicrosoft has announced the release of .NET Core 1.0 and ASP.NET Core 1.0, the open source, cross-platform fork of the .NET Framework, letting people know at the Red Hat DevNation summit in San Francisco.The company has even registered the domain redhatloves.net, which redirects to a site with developer resources for .NET on Red Hat Enterprise Linux.Linux can be deployed on its Azure cloud, and there is strong .NET support for both Office 365 and Azure.The Eclipse Che team, whose project is a browser-based IDE, announced support for the Visual Studio Code language server protocol, which means Eclipse Che can share code to enable rich editing features.Visual Basic is not supported for ASP.NET Core, and the SignalR real-time communication framework is not yet done.Version 1.1 will change the build system to MSBuild, which means .csproj configuration files in place of the current project.json.

Redmond also unveils Windows 10 Enterprise subscription packages as Windows Server 2016 gets launch dateMicrosoft has started offering Surface as a Service subscriptions in a bid to bring up enterprise adoption of Windows 10.The Surface service means that Microsoft s CSPs Cloud Solution Providers can now sell Surface as a Service.Essentially, Surface devices can now be sold to customers of channel partners on a subscription basis.Moreover, Microsoft has done the same for Windows 10 Enterprise Edition, allowing channel partners to sell Windows 10 subscriptions at $7 £5.30 per person per month via the Cloud Solution Provider channel.The subscriptions are ideal for businesses that do not have dedicated IT resources or have limited IT staff, and want their licensing and IT needs managed by a trusted and experienced partner said Microsoft today at its Worldwide Partner Summit in Toronto.
Microsoft today announced the release of a new Windows 10 build for PCs and mobile for people participating in the fast ring of the Windows Insider Program.Today s release, of build 14388, comes three days after Microsoft rolled out build 14385, which itself appeared two days after build 14383.Microsoft has been busy preparing for the Anniversary Update, which will hit on August 2, so it s not a surprise to see that this build squashes a few bugs and not much more than that.Two of today s fixes involve Narrator, the screen reader that comes standard with Windows.Now Narrator s keyboard shortcuts will work after locking a PC and then logging back in and navigating to the desktop, and also the application will read out the date and time when you go to the Date & time menu in the Time & language section of Settings, Dona Sarkar, a software engineer in Microsoft s Windows and Devices Group, wrote in a blog post.Today s build also comes with a new version of the Store app, Sarkar wrote.The build contains two known issues.First, Windows Server 2016 Technical Preview 5 will not be able to boot virtual machines when the Secure Boot option is turned on — Microsoft recommends people use the software with Secure Boot turned off.Second, when this build is used in languages other than US English, the error code 0x80004005 could come up when you turn on Developer Mode, even though Developer Mode does actually get turned on.
Microsoft has released details of how Windows Server 2016 will be released and maintained, and as with Windows 10 it includes a "Windows as a service" model of frequent operating system updates.Windows Server 2016 will be launched at the company's Ignite conference, which runs from September 26 to 30 in Atlanta, Georgia.As with the current release, there will be three editions: Datacenter, Standard and Essentials.Nano Server has no GUI and can only be managed remotely.Datacenter and Standard can be installed either as Long-Term Servicing Branch LTSB – with five years of mainstream support and five years of extended support – or as Current Branch for Business CBB , in which case you can expect feature updates two or three times a year.These terms are familiar from Microsoft's Windows 10 release, which follows a similar pattern.
It's not quite an exact launch date, but Microsoft has announced that both Windows Server 2016 and System Center 2016 will launch at its Ignite conference the successor to TechEd this fall.Ignite runs from September 26-30 and is being held in Atlanta, Georgia.Microsoft has also described how Windows Server 2016 will be serviced going forward.Full installations of the operating system—including the GUI and shell—will continue to be serviced on the "5 5" model that Microsoft has used for previous operating systems.That's five years of mainstream support, during which both bug fixes and feature improvements are made, and then five years of extended support, during which only security bugs will be fixed.The slimmed down Server Core installation will also be given this 5 5 servicing.
Microsoft s new batch of security patches fixes 47 vulnerabilities across its products, including in Internet Explorer, Edge, Office, Windows and the .NET Framework.The patches, released Tuesday, are arranged in 11 security bulletins, 10 of which are for Microsoft products.The remaining patch covers Adobe Flash Player, which is bundled with Internet Explorer in Windows 8.1, Windows Server 2012, Windows RT 8.1, Windows Server 2012 R2 and Windows 10.Six security bulletins, including the Flash Player one, are rated critical and primarily cover remote code execution vulnerabilities that could lead to a complete system compromise.Aside from the typical browser flaws that can be exploited through malicious webpages and those in Office that can be exploited through specifically crafted documents, two others stand out: one in the JScript and VBScript scripting engines of Windows and one in the operating system s Print Spooler service.It can be exploited through malicious code hosted on websites or through an ActiveX control marked as safe for initialization in an application or Microsoft Office document that hosts the IE rendering engine.
