Technology has come a long way from adding machines, mainframe systems, Computers that take up 500sq ft. off office space using 12"floppy disks to a highly technology advanced infrastructure using 10TB Hard drives. I question weather or not cloud computing is the solution for every company. Cloud computing helps for redundancy and offsite data however security is a major key in keeping company data safe. Perhaps the biggest concerns about cloud computing are security and privacy. The idea of handing over important data to another company worries some people. Corporate executives might hesitate to take advantage of a cloud computing system because they can't keep their company's information under lock and key.
The counterargument to this position is that the companies offering cloud computing services live and die by their reputations. It benefits these companies to have reliable security measures in place. Otherwise, the service would lose all its clients. It's in their interest to employ the most advanced techniques to protect their clients' data.
Privacy is another matter. If a client can log in from any location to access data and applications, it's possible the client's privacy could be compromised. Cloud computing companies will need to find ways to protect client privacy. One way is to use authentication techniques such as user names and passwords. Another is to employ an authorization format -- each user can access only the data and applications relevant to his or her job. Encryption is another option, this is being utilized by many healthcare agencies, law firms, and finance companies
Some questions regarding cloud computing are more philosophical. Does the user or company subscribing to the cloud computing service own the data? Does the cloud computing system, which provides the actual storage space, own it? Is it possible for a cloud computing company to deny a client access to that client's data? Several companies, law firms and universities are debating these and other questions about the nature of cloud computing.
How will cloud computing affect other industries? There's a growing concern in the IT industry about how cloud computing could impact the business of computer maintenance and repair. If companies switch to using streamlined computer systems, they'll have fewer IT needs. Some industry experts believe that the need for IT jobs will migrate to the back end of the cloud computing system.
Another area of research in the computer science community is autonomic computing. An autonomic computing system is self-managing, which means the system monitors itself and takes measures to prevent or repair problems. Currently, autonomic computing is mostly theoretical. But, if autonomic computing becomes a reality, it could eliminate the need for many IT maintenance jobs.
Windows 10 adoption keeps slowing as Microsoft plans aggressive upgrades
After getting off to a speedy start, Windows 10 adoption is continuing to flatten out.
In October, NetApplications estimated 7.94 market share among desktop operating systems for Windows 10, based on unique visits to a sampling of websites. That’s up from 6.63 percent in September, and 5.21 percent in August.
StatCounter, another metrics firm that measures usage share by pageviews on sample sites, estimated 9 percent usage for Windows 10 in October. That’s compared to 7.64 percent in September, and 5.38 percent in August.
Windows 7 remains the dominant desktop operating system according to both metrics firms, with 55.71 percent share according to NetApplications, and 50.26 percent according to StatCounter.
Why this matters: By offering free upgrades for consumers through next fall, Microsoft is hoping to break the cycle in which the most popular Windows versions are outdated or unsupported. From Windows 10 onward, Microsoft will deliver automatic updates, while making money through built-in services such as the Edge browser, Bing search, and the Cortana virtual assistant. The revenue plan isn’t going terribly, as Bing finally became profitable last quarter, but the latest usage data shows that older Windows versions aren’t going away anytime soon.
The slowing uptake of Windows 10 may explain why Microsoft is planning to get more aggressive with upgrades. Sometime next year, Microsoft will re-categorize Windows 10 as a “Recommended” update, rather than an optional one.
That means users who’ve chosen to receive recommended updates will download the Windows 10 installation files automatically. Depending on the user’s settings, the installation might also begin automatically. (Microsoft says users will still have an option to back out of the installation, and can roll back to a previous version of Windows anytime within the first 31 days.)
While Windows 10 is largely an improvement over previous versions, users may not want to upgrade for a variety of reasons, including software compatibility or comfort with their current version. The automatic download could also cause problems for users on metered connections, who will no longer be able to get automatic security patches without also downloading several gigabytes’ worth of Windows 10 installation files.
From Nano and Docker to software-defined networking and storage features, the next version of Windows Server is packed with great additions
Microsoft continues to put out Technical Previews of Windows Server 2016 with as-yet-unseen features. The latest Technical Preview, TP3, introduced a number of new features, such as Docker integration and Windows Server Containers, along with improvements to features introduced in previous previews. It also brings new security capabilities such as Shielded VMs, which protect virtual machine contents in a multitenant environment.
This guide, available in both PDF and ePub editions, explains the security capabilities inherent to
The TP2 release debuted Nano Server and a number of Hyper-V, networking, and storage features. It introduced a new Windows Server role named Host Guardian Service, which flags trusted Hyper-V hosts, and included a Windows Server Antimalware feature not found in previous previews. Forthcoming Technical Previews will bring more new features, notably Hyper-V Containers.
But while the hits keep coming and the complete picture of Windows Server 2016 is still forming, it’s not too soon to weigh in on some of our favorites. We’ll update this list as more Technical Previews, and eventually beta versions, arrive. In the meantime, here are the Windows Server 2016 features we like the most.
Technical Preview 3 provides the first look at Windows Server Containers and includes everything you need to get started testing this technology on Windows. Installation requires only two commands in an elevated PowerShell window:
wget -uri https://aka.ms/setupcontainers -OutFile C:ContainerSetup.ps1
It’s important to note at this point that Microsoft supports two different container models: Windows Server Containers and Hyper-V Containers. Windows Server Containers use the standard Docker concepts, running each container as an application on top of the host OS. Hyper-V Containers will be completely isolated virtual machines, incorporating their own copy of the Windows kernel, but more lightweight than traditional VMs. Hyper-V Containers will make it possible to do nested virtualization within Hyper-V. New PowerShell cmdlets provide an alternative to Docker commands to manage your containers (see Figure 1).
Container images are built against a specific operating system. This means you'll need a Linux virtual machine to run a Linux container image on Windows. Windows Server Containers will be an embedded feature of Windows Server 2016 and work with the Docker ecosystem out of the box. Microsoft is using GitHub for posting Windows versions of the different Docker components and encourages participation from the developer community.
ws2016 containers fig1
Figure 1: You can manage Windows Server Containers (and Hyper-V Containers when they arrive) through native Docker commands or through PowerShell (shown).
Refactoring is the process of analyzing an existing code base with an eye toward simplification. Nano is the end result of Microsoft refactoring the core pieces of Windows Server to its minimally functional state. It's so minimal, in fact, that it doesn't have any direct user interface besides the new Emergency Management console. A Nano instance is managed remotely using Windows PowerShell, or other tools, to include the process of adding new roles.
A Nano instance consumes not much more than 512MB of disk space and less than 256MB of memory, depending on your configuration. This will make a huge difference for all virtual machines built on top of Nano, which will function as an infrastructure host installed on bare metal and as a guest OS running as a virtualized machine. New in Technical Preview 3 is an Emergency Management Console that allows you to view and fix networking issues directly from the Nano Server console. Nano Azure VM instances can be created with a Microsoft-supplied PowerShell script and now support running ASP.Net v5 applications using CoreCLR.
Microsoft has supported replication in the world of Hyper-V, but it has been limited up to this point to asynchronous replication of virtual hard disks. That changes with Windows Server 2016, as you now have the ability to replicate entire volumes at the block level. Further, you can choose between synchronous and asynchronous replication.
This feature, called Storage Replica, is primarily aimed at disaster recovery scenarios where a “hot” backup is needed for a quick fail-over in case of a major catastrophe. Both server-to-server and cluster-to-cluster replication are supported.
Storage Spaces Direct
Both Windows 8 and Windows Server 2012 shipped with Storage Spaces, which provides similar functionality to RAID but in software. Windows Server 2012 R2 added the ability to build a highly available storage cluster based on the same Storage Spaces technology and Microsoft clustering. The one big requirement for this high-availability cluster is making all storage accessible to participating nodes through an external JBOD array. The JBOD array must also contain SAS drives for their multi-initiator support.
Windows Server 2016 Technical Preview 2 takes Storage Spaces a step further, with the ability to build a highly available storage system using only directly attached disks on each node. Resiliency across nodes uses the network and the SMB3 protocol. This new feature, called Storage Spaces Direct, also takes advantage of new hardware like NVMe SSDs, while still supporting older SATA-based hardware. A minimum of four nodes must be available to create a cluster with Storage Spaces Direct.
ReFS as primary file system
The Resilient File System (ReFS) is another feature that was introduced with Windows 8 and Windows Server 2012. Designed from the beginning to be more resistant to corruption than its predecessor, ReFS brings many advantages to the NTFS on-disk format. Microsoft has elevated both the usefulness and the importance of ReFS in Windows Server 2016 TP2 by making it the preferred file system for Hyper-V workloads.
This has huge performance implications for Hyper-V. For starters, you should see new virtual machines with a fixed-size VHDX created almost as fast as you hit return. The same advantages apply to creating checkpoint files and to merging VHDX files created when you make a backup. These capabilities resemble what ODX (Offload Data Transfers) can do on larger storage appliances. One point you need to keep in mind is that ReFS allocates the storage for these operations without initializing it, meaning there could be residual data left over from previous files.
Hyper-V rolling upgrades
Upgrading to a new operating system presents significant challenges on many fronts. In previous versions of Windows Server, it was not possible to upgrade a cluster without taking it down. This can be a significant issue for production systems, which typically run continuously. Often the workaround was to stand up a new cluster running the updated operating system, then live-migrate the workloads from the old cluster. Naturally, this required totally new hardware to accomplish.
Windows Server 2016 supports rolling cluster upgrades from Windows Server 2012 R2, meaning you can perform these upgrades without taking down the cluster or migrating to new hardware. The process is similar in that individual nodes in the cluster must have all active roles moved or evicted to another node in order to upgrade the host operating system. The difference is that all members of the cluster will continue to operate at the Windows Server 2012 R2 functional level (and support migrations between old and upgraded hosts) until all hosts are running the new operating system and you explicitly upgrade the cluster functional level (by issuing a PowerShell command).
Rolling cluster upgrades should reduce the effort needed and hopefully make the process of upgrading less painful for production environments.
Hyper-V hot add NICs and memory
Previous versions of Hyper-V did not allow you to add a network interface or more memory to a running virtual machine. Because downtime is always bad but change is sometimes good, Microsoft now allows you to make some critical machine configuration changes without taking the virtual machine offline. The two most important changes involve networking and memory.
Figure 2 shows the hardware settings dialog for a virtual machine named Windows Server 2016 TP2 with the virtual machine running. Notice that the Network Adapter entry in the Add Hardware dialog is no longer grayed out. This allows an administrator to add network adapters while the VM is running. Similarly, VMs with fixed amounts of memory can now have memory added. Previous versions of Hyper-V supported dynamic memory allocation (that is, the VM would consume only what it needed up to the amount provisioned) but did not allow a VM with a fixed amount of memory to be modified while running.
Convergence is the buzzword here with new features coming to help enterprises and hosting providers merge traffic from multiple tenants to reduce the number of network interfaces. This can reduce the required number of network ports by as much as half in some cases. Another new capability is called Packet Direct, which focuses on increasing efficiency across workloads to include everything from small packets to large data transfers.
Technical Preview 3 includes a new server role called Network Controller, which provides a central point for monitoring and managing network infrastructure and services. Other enhancements supporting the software-defined network capabilities include an L4 load balancer, enhanced gateways for connecting to Azure and other remote sites, and a converged network fabric supporting both RDMA and tenant traffic.
Storage QoS updates
Storage Quality of Service (Storage QoS) was introduced with Hyper-V in Windows Server 2012 R2, making it possible to place limits on the amount of IO that individual VMs could consume. The initial release of this feature was limited to placing QoS limits at the Hyper-V host level. As a result, the current version of Storage QoS works well in a small environment, but can present a challenge when you need to balance IOs across multiple hosts.
Windows Server 2016 allows you to centrally manage Storage QoS policies for groups of virtual machines and enforce those policies at the cluster level. This could come into play in the case where multiple VMs make up a service and should be managed together. PowerShell cmdlets have been added in support of these new features, including Get-StorageQosFlow, which provides a number of options to monitor the performance related to Storage QoS; Get-StorageQosPolicy, which will retrieve the current policy settings; and New-StorageQosPolicy, which creates a new policy.
PowerShell continues to receive updates with each new release of the operating system. Windows Server 2016 will see a significant number of new PowerShell cmdlets focused on specific functionality. You can even use PowerShell commands to check each new release to see the differences. The PowerShell cmdlet Get-Command returns a list of commands that can be sent to a file for further processing. Microsoft’s Jose Barreto posted instructions on his blog for exactly this.
New cmdlets of interest include 21 DNS-related commands, 11 for Windows Defender, 36 for Hyper-V, 17 for IIS administration, and 141 commands related to the Network Controller, to name a few. The other big push for PowerShell in this release relates to Desired State Configuration (DSC). Microsoft has done a lot of work to make DSC the tool for initially configuring and maintaining not only Windows Server, but also Linux servers. When you throw in the new package manager service, OneGet, you have tons of new PowerShell-driven possibilities.
As increasing numbers of workloads move to virtualized instances in the cloud, it becomes important to reduce the footprint of each instance, to increase the security around them, and to bring more automation to the mix. It also makes sense to provide more advanced networking and storage functionality in software. In Windows Server 2016, Microsoft is pushing ahead on all of these fronts all at once.
VMware has found, and is trying hard to fix, a nasty bug in ESXi 6.0.
Issue 2124669, causes “ESXi 6.0 host network connectivity' to be “lost randomly.”
Once the connectivity is lost, “ESXi enters into a non-responding state and becomes unmanageable until reboot.”
Forget about re-connecting to networks until you reboot, but even after you've given ESXi the three-finger salute “the issue is temporarily resolved for a period of time, but occurs again after a random interval”.
The good news is there's a workaround in the form of a script (.ZIP), but VMware warns the fix can slug your CPU pretty hard.
The company says it “... is working aggressively to resolve this issue”, as of September 14th.
ESXi 6.0 is part of vSphere 6.0 , for which VMware just released the first major update. VMware says it's never seen better uptake for a vSphere release, but also tells us there are masses of vSphere 5.5 users it hopes will make the leap sooner rather than later. Later sounds more sensible while Virtzilla stomps this bug. ®
