Microsoft announcing SQL Server on Linux – #SQL, #Microsoft, #DB, #PaaS

This is sooo cool and further shows how Microsoft has changed over the past years!

SQL-Loves-Linux

It’s been an incredible year for the data business at Microsoft and an incredible year for data across the industry. This Thursday at our Data Driven event in New York, we will kick off a wave of launch activities for SQL Server 2016 with general availability later this year. This is the most significant release of SQL Server that we have ever done, and brings with it some fantastic new capabilities. SQL Server 2016 delivers:

  • Groundbreaking security encryption capabilities that enable data to always be encrypted at rest, in motion and in-memory to deliver maximum security protection
  • In-memory database support for every workload with performance increases up to 30-100x
  • Incredible Data Warehousing performance with the #1, #2 and #3 TPC-H 10 Terabyte benchmarks for non-clustered performance, and as of March 7, the #1 SAP SD Two-Tier performance benchmark on Windows1
  • Business Intelligence for every employee on every device – including new mobile BI support for iOS, Android and Windows Phone devices
  • Advanced analytics using our new R support that enables customers to do real-time predictive analytics on both operational and analytic data
  • Unique cloud capabilities that enable customers to deploy hybrid architectures that partition data workloads across on-premises and cloud based systems to save costs and increase agility

These improvements, and many more, are all built into SQL Server and bring you not just a new database but a complete platform for data management, business analytics and intelligent apps – one that can be used in a consistent way across both on-premises and the cloud. In fact, over the last year we’ve been using the SQL Server 2016 code-base to run in production more than 1.4 million SQL Databases in the cloud using our Azure SQL Database as a Service offering, and this real-world experience has made SQL Server 2016 an incredibly robust and battle-hardened data platform.

Gartner recently named Microsoft as leading the industry in their Magic Quadrant for Operational Database Management Systems in both execution and vision. We’re also a leader in Gartner’s Magic Quadrant for Data Warehouse and Data Management Solutions for Analytics, and Magic Quadrant for Business Intelligence and Analytics Platforms, as well as leading in vision in the Magic Quadrant for Advanced Analytics Platforms.

Extending SQL Server to Also Now Run on Linux

Today I’m excited to announce our plans to bring SQL Server to Linux as well. This will enable SQL Server to deliver a consistent data platform across Windows Server and Linux, as well as on-premises and cloud. We are bringing the core relational database capabilities to preview today, and are targeting availability in mid-2017. Read more…

Microsoft and AzureCon delivers! Love it! – #Azure, #AzureCon, #EnvokeIT, #IoT, #SaaS, #PaaS

I really love the way that Microsoft and Azure delivers! It’s so amazing with all the PaaS and SaaS offerings they now have on top of the traditional IaaS delivery. There is no other cloud provider out there that delivers anything near it! I’m amazed and so happy to be a part of this journey!

If you didn’t have the time to look at AzureCon you have a lot of great videos and topics to go through!!

Here is a short overview of the many great things released and presented:

  • General Availability of 3 new Azure regions in India
  • Announcing new N-series of Virtual Machines with GPU capabilities
  • Announcing Azure IoT Suite available to purchase
  • Announcing Azure Container Service
  • Announcing Azure Security Center

Watching the Videos

All of the talks presented at AzureCon (including the 60 breakout talks) are now available to watch online.  You can browse and watch all of the sessions here.

Announcing General Availability of 3 new Azure regions in India

Yesterday we announced the general availability of our new India regions: Mumbai (West), Chennai (South) and Pune (Central).  They are now available for you to deploy solutions into.

This brings our worldwide presence of Azure regions up to 24 regions, more than AWS and Google combined. Over 125 customers and partners have been participating in the private preview of our new India regions.   We are seeing tremendous interest from industry sectors like Public Sector, Banking Financial Services, Insurance and Healthcare whose cloud adoption has been restricted by data residency requirements.  You can all now deploy your solutions too.

Announcing N-series of Virtual Machines with GPU Support

This week we announced our new N-series family of Azure Virtual Machines that enable GPU capabilities.  Featuring NVidia’s best of breed Tesla GPUs, these Virtual Machines will help you run a variety of workloads ranging from remote visualization to machine learning to analytics.

The N-series VMs feature NVidia’s flagship GPU, the K80 which is well supported by NVidia’s CUDA development community. N-series will also have VM configurations featuring the latest M60 which was recently announced by NVidia. With support for M60, Azure becomes the first hyperscale cloud provider to bring the capabilities of NVidia’s Quadro High End Graphics Support to the cloud. In addition, N-series combines GPU capabilities with the superfast RDMA interconnect so you can run multi-machine, multi-GPU workloads such as Deep Learning and Skype Translator Training.

Announcing Azure Security Center

This week we announced the new Azure Security Center—a new Azure service that gives you visibility and control of the security of your Azure resources, and helps you stay ahead of threats and attacks.  Azure is the first cloud platform to provide unified security management with capabilities that help you prevent, detect, and respond to threats.

Azure_Security_Center

The Azure Security Center provides a unified view of your security state, so your team and/or your organization’s security specialists can get the information they need to evaluate risk across the workloads they run in the cloud.  Based on customizable policy, the service can provide recommendations. For example, the policy might be that all web applications should be protected by a web application firewall. If so, the Azure Security Center will automatically detect when web apps you host in Azure don’t have a web application firewall configured, and provide a quick and direct workflow to get a firewall from one of our partners deployed and configured: Read more…

See how Citrix XenDesktop for Linux looks – #Citrix, #XenDesktop, #Linux, #EnvokeIT, #BYOD, #DaaS

June 4, 2015 1 comment

This is one of the coolest things a part from the Workspace Cloud service that Citrix is working on. I’ve had the pleassure of trying this out and we at EnvokeIT have been doing a lot of tests of this Linux VDA tech preview.

Isn’t it great that both Microsoft and Citrix now seem to love Linux 🙂   (and yes, I manipulated these images so it’s not an official Citrix statement!)Richard_happy_when_Microsoft_and_Citrix_Loves_Linux

So this little blog post is just going to show of the capabilities and how nicely this integrates with the Citrix XenDesktop architecture. First of all I’d like to say thanks to my colleagues Björn Bekkouche and Peter Smali for letting me use their lab environment!

Before we get into showing how it works and looks I must just highlight that if you have any questions about how we can assist you to deliver Linux-based Terminal Servers or VDI’s to remote users in a secure and optimal just contact us at EnvokeIT here or pop me an email: richard at envokeit.com.

This is great for all of you with Developers on Linux! Have them code from anywhere in a secure manner! They can run their Linux VDA in your datacenter, connect to it from an Receiver compliant device and code from them and you have your intellectual property secured internally instead of having them checking out Git repositories to their local devices etc.!

So what is XenDesktop for Linux? Well, to answer that really simple I assume that you have some basic knowledge of the Citrix XenDesktop architecture.. if you don’t then please read up on that a little before continue reading, one really good contribution to bulding your architecture is described in this Citrix Virtual Desktop Handbook or this Citrix XenDesktop – Blueprint. These contains a lot of valuable information that you shall think of and how to configure the environment to fulfill you use cases.

But overall think of the XenDesktop architecture of something like the following pictures (click to enlarge them). The first one shows the new model where we could run and take care of the VDA’s ourselves on-premise but leverage the Workspace Cloud service from Citrix so that we don’t anymore have to bother about the XenDesktop infrastructure components and the life-cycle management etc. of those. The second one is the more overall traditional architecture overview that you’d see of the different layers.

Apps-Service-Overview

XenDesktop_overview_architecture

And as you see above this details the standard architecture wher you would have your Server or Desktop VDA’s in the resource layer hosting the desktops for your users to connect to, but they have all been Windows-based up until now!

Now with the Tech Preview we can actually install the Linux-based VDA on a Red Hat or Suse machine and access that through the SAME Delivery Controllers and StoreFront stores that also manage our Windows-based VDA’s.

And this is awesome! 🙂 We can leverage the already existing Windows-based architecture to just “hook in” our Linux-desktops as well and get users to conect through Receiver for Web, Receiver and even through the NetScalers if you need (works like a charm!!).

So as you can see here we have a nice little landing page for our entry points that are running different versions and access different environments etc.

So we have Peters entry point running one NetScaler version and theme: Read more…

Microsoft Ignite 2015 summary – #MSIgnite, #EnvokeIT, #Azure, #Office365, #OneDrive, #EMM, #PaaS, #IaaS

Hi all,

We at EnvokeIT participated and collaborated at Microsoft Ignite 2015 in Chicago. And it was one of the most intense events I’ve visited in years with a lot of happening in the business and Microsoft really showed that they are the leading innovator in many areas!

I hope that you enjoy my report and that it gives you a condensed overview of what happened and please contact us at EnvokeIT if you want assistance within any area below! And thank you Microsoft for such a great event and also all you bloggers out there that I’ve linked to in this material.

I must say that this event was positive and a bit scary at the same time. Microsoft is for sure pushing as visionairies and innovators in a lot of areas, and I think that competitors will have a hard time competing in the coming years.

These are the areas where A LOT have been released already and where Microsoft according to my oppinion will increase its market share significantly:

  • Cloud and Mobile services, and with this I don’t mean IaaS service for just running a VM in their public Azure cloud or building a hybrid cloud with connectivity to on-premise datacenters. They are delivering so many capabilities now as PaaS and SaaS services. Just look at the sections below, it’s everything from Enterprise Mobillity Management (EMM), Business Intelligence, Database, Storage, Web Apps/services, Service Availability services (DR, Monitoring/Reporting, Backup etc.), Development, Source Control, Visual Studio Online etc. It’s amazing!!
  • Open Source/Linux support – It’s so cool how much Microsoft have shifted to become an adopter to support more open source technologies and way of thinking than just a couple of years ago! Just have a look at all the Linux support they have in Azure, the Linux support they now have in System Center, Docker support to deliver more DevOps capabilities and all the other services in Azure. It’s amazing and so fun! So now both Microsoft have opened their eyes and realized that they can’t ignore this anymore just like Citrix has with their addition of XenDesktop for Linux with SuSE and RedHat support!

The first day kicked off and was a bombarding of product announcements aimed at helping IT pros secure and manage the new Universal Windows Platform.

CEO Satya Nadella presided over a three-hour keynote, which focused on how Microsoft’s new wave of software and cloud services will enable IT and business transformations that are in line with the ways people now work. Nadella talked up Microsoft’s focus on “productivity and platforms” and how it’s tied with the shift to cloud and mobility. He also highlighted the need for better automation of systems and processes, and better management of the vast amounts of data originating from new sources such as sensors and other Internet-of-Things-type nodes.

As mentioned there where a lot of updates and below I’ve tried to gather these and I hope it gives you a good insight on the infromation we received and also guidance on how you can get more information about the topics.

Included below are links to detailed overviews of each of the demos (from Microsoft blog post) – including information about how to use them, where to learn more, and what you’ll need to get started.

The following picture is a sketch of the keynote and is also quite good at summarizing the message of Mobile and Cloud first!

 

vNiklas also created a great powershell script that automates the downloading of all MS Ignite content with PowerShell and Bits from Channel 9 that you can find here!

Enterprise Mobility Management (EMM) – MDM, MAM, MCSM/MIM etc…

Microsoft’s next chapter in Enterprise Mobility, great blog post on where Microsoft is going etc. http://blogs.technet.com/b/enterprisemobility/archive/2015/05/04/ignite-microsofts-next-chapter- in-enterprise-mobility.aspx …

Windows 10 Continuum – this is cool, think about docking your smartphone to your external screen, keyboard and mouse! That’s try mobility of youre device, this looks really cool and something that I’d like to try out once released!

Have a look at the feature demo at Ignite in the video below.

Office 2016 public preview available!

Over the last 12 months, we’ve transformed Office from a suite of desktop applications to a complete, cross-platform, cross-device solution for getting work done. We’ve expanded the Office footprint to iPad and Android tablets. We’ve upgraded Office experiences on the Mac, the iPhone and on the web. We’ve even added new apps to the Office family with Sway and Office Lens. All designed to keep your work moving, everywhere. But that doesn’t mean we’ve forgotten where we came from. While you’ve seen us focus on tuning Office for different platforms over the last year, make no mistake, Office on Windows desktop is central to our strategy.

In March we introduced an IT Pro and Developer Preview for the 2016 release of our Office desktop apps on Windows, and now—as a next step—we’re ready to take feedback from a broader audience. Today we’re expanding the Office 2016 Preview, making it available to Office users everywhere in preparation for general availability in Fall 2015.

Office 2016 previewers will get an early look at the next release of Office on Windows desktop, but more importantly they’ll help to shape and improve the future of Office. Visit the Office 2016 Preview site to learn more about the Preview program and if it’s right for you.

New in Office 2016

Since March, we’ve shared some glimpses of what’s to come in Office 2016. Today, we’d like to give a more holistic view of what customers at home and work can expect in the next release. In Office 2016, we’re updating the Office suite for the modern workplace, with smart tools for individuals, teams, and businesses.

Highly critical “Ghost” allowing code execution affects most Linux systems – #Vulnerability, #Security, #Linux

January 29, 2015 Leave a comment

And here it continues, another critical vulnerability that affects most Linux systems. Ensure that your system is updated and rebooted!!

More information about Citrix affected systems can be found here:

Citrix Security Advisory for glibc GHOST Vulnerability (CVE-2015-0235)
http://support.citrix.com/article/CTX200391

Here is a great article on the vulnerability itself from arstechnica.com:

An extremely critical vulnerability affecting most Linux distributions gives attackers the ability to execute malicious code on servers used to deliver e-mail, host webpages, and carry out other vital functions.

The vulnerability in the GNU C Library (glibc) represents a major Internet threat, in some ways comparable to the Heartbleed and Shellshock bugs that came to light last year. The bug, which is being dubbed “Ghost” by some researchers, has the common vulnerability and exposures designation of CVE-2015-0235. While a patch was issued two years ago, most Linux versions used in production systems remain unprotected at the moment. What’s more, patching systems requires core functions or the entire affected server to be rebooted, a requirement that may cause some systems to remain vulnerable for some time to come.

The buffer overflow flaw resides in __nss_hostname_digits_dots(), a glibc function that’s invoked by the gethostbyname() and gethostbyname2() function calls. A remote attacker able to call either of these functions could exploit the flaw to execute arbitrary code with the permissions of the user running the application. In a blog post published Tuesday, researchers from security firm Qualys said they were able to write proof-of-concept exploit code that carried out a full-fledged remote code execution attack against the Exim mail server. The exploit bypassed all existing exploit protections available on both 32-bit and 64-bit systems, including address space layout randomization, position independent executions, and no execute protections. Qualys has not yet published the exploit code but eventually plans to make it available as a Metasploit module.

“A lot of collateral damage on the Internet”

The glibc is the most common code library used by Linux. It contains standard functions that programs written in the C and C++ languages use to carry out common tasks. The vulnerability also affects Linux programs written in Python, Ruby, and most other languages because they also rely on glibc. As a result, most Linux systems should be presumed vulnerable unless they run an alternative to glibc or use a glibc version that contains the update from two years ago. The specter of so many systems being susceptible to an exploit with such severe consequences is prompting concern among many security professionals. Read more…

#Citrix #Receiver for Linux 13 released

November 13, 2013 Leave a comment

Finally Citrix has released a Receiver version for Linux that for instance has StoreFront support! Can’t wait to try it out and see if it gives the same user  experience etc like the one on OS X and Windows!

Here you have some details about it and links to the product documentation:

Access Windows applications and virtual desktops, as well as web and SaaS applications. Enable anywhere access from your Linux thin client/desktop or use web access.

What’s new

The following new features are available in this release:

  • Support for XenDesktop 7 features – Receiver supports many of the new features and enhancements in XenDesktop 7, including Windows Media client-side content fetching, HDX 3D Pro, HDX RealTime webcam compression, Server-rendered Rich Graphics, and IPv6 support.
    Note: Link-local network addresses are not supported in IPv6 environments. You must have at least one global or unique-local address assigned to your network interface.
  • VDI-in-a-Box support – You can use Receiver to connect to virtual desktops created with Citrix VDI-in-a-Box.
  • Self-service UI – A new graphical user interface (UI), like that in other Citrix Receivers, replaces the configuration manager, wfcmgr. After they are set up with an account, users can subscribe to desktops and applications, and then start them.
  • Deprecated and removed utilities – The pnabrowse command-line utility is deprecated in favor of the new storebrowse command-line utility. The icabrowse and wfcmgr utilities have been removed.
  • StoreFront support – You can now connect to StoreFront stores as well as Citrix XenApp sites (also known as Program Neighborhood Agent sites).
  • UDP audio support – Most audio features are transported using the ICA stream and are secured in the same way as other ICA traffic. User Datagram Protocol (UDP) Audio uses a separate, unsecured, transport mechanism, but is more consistent when the network is busy. UDP Audio is primarily designed for Voice over IP (VoIP) connections and requires that audio traffic is of medium quality (that is Speex wideband) and unencrypted.
  • Packaging – An armhf (hard float) Debian package and tarball are now included in the download packages. In addition, the Debian package for Intel systems uses multiarch (a Debian feature) for installations on 32- and 64-bit systems. 32-bit binaries are also available in RPM packages.
  • System Flow Control – Video display has been enhanced on low-performance user devices that connect to high-performance servers. In such setups, System Flow Control prevents sessions becoming uncontrollable and unusable.
  • Localization – Receiver is now available in German, Spanish, French, Japanese, and Simplified Chinese.
  • Keyboard improvements – You can now specify which local key combination (Ctrl+Alt+End or Ctrl+Alt+Enter) generates the Ctrl+Alt+Delete combination on a remote Windows desktop. In addition, a new option supports Croatian keyboard layouts.
  • Deferred XSync – While one frame is still on screen, Receiver can now decode tiles for the next frame. This provides a performance improvement compared with previous releases, in which Receiver waited for a frame to finish being displayed before decoding the next frame.
  • Audio and webcam playback improvements – Various changes are implemented that conserve CPU cycles and reduce latency.
  • Audio settings – Several new audio settings are now available in module.ini.
