Citrix Workspace app is released Hello World

The views expressed here are my own and do not necessarily reflect the views of Citrix.

Introduction
What is Citrix Workspace app? It brings together all your LOB tools which in todays modern world consists of (virtual/micro/installed/mobile) apps, SaaS, desktops & content. I’ve embedded a sample of what this actually looks like below.

Overview
The new Citrix Workspace app way more than purely an upgrade of Citrix Receiver e.g grey to blue icon and a skin change, this NEW Citrix client app release is simply extraordinary, working for Citrix I can be considered bias however once you actually begin to consume the Citrix Workspace app you’ll understand exactly what I mean. Citrix Workspace app is for me all about an experience, and that experience is extraordinarily AWESOME! As I begin consuming my LOB (Line of Business) tools wherever I am + want and in a setting/context that suites me (home, Paddington vs. partner offices, trains, taxi e.t.c) the chosen LOB tool delivered context can change dependant upon criteria (I won’t be covering this today) or how IT (say YES!) has chosen to deliver the LOB tool through Citrix Access Control Service – https://docs.citrix.com/en-us/citrix-cloud/access-control/get-started.html.

I now have all my content available all in the same AWESOME app thank you Citrix Content & Collaboration aka ShareFile. I can upload, download and even favourite particular content e.g “L-J’s H1/2 Citrix Partner Tech Super Deck” which is then available directly from the home view/tab. In the below example I am uploading the LeasePlan Citrix SD-WAN case study – https://www.citrix.co.uk/customers/leaseplan-en.html and the actual video is available at – https://www.youtube.com/watch?v=4Hq-yryxfS0 take a look and remember to listen to the outcomes Citrix SD-WAN provides LeasePlan.

How do I get started today?
Firstly I will do a more detail blog post on getting it all up and running with use cases time dependant of course.

1.Start by navigating to https://docs.citrix.com/en-us/citrix-workspace-app.html and then goto Citrix.com and login with your access details, next navigate to https://www.citrix.com/downloads/workspace-app/ and download Citrix Workspace app for your chosen end-point. If you are running a TP of Citrix Workspace app code base please UNINSTALL it prior to installing the GA production code base as a few community individuals I know had issues upgrading from TP code base. I would like to state for the record I upgraded from PRODUCTION Citrix Receiver to the Citrix Workspace app for Mac 1808 on my Mac without ANY issues see below tweet.

2. Please carefully read the System Requirements for your chosen platform here is the link for Mac – https://docs.citrix.com/en-us/citrix-workspace-app-for-mac/system-requirements.html and Windows https://docs.citrix.com/en-us/citrix-workspace-app-for-windows/system-requirements.html.

5. Sign-up vs. Login to Citrix Cloud today and trial vs. acquire a Citrix Cloud service e.g ShareFile Service or the XAD Service and if you want to aggregate on-premises LOB apps into the new Citrix Workspace experience then setup “Site Aggregation” today. To learn how please read this CTXS blog post and watch the embedded YouTUBE video which provides a how-to overview at – https://www.citrix.com/blogs/2018/08/03/site-aggregation-for-citrix-workspace-is-now-ga/.

Thats all folks for now on the technical overview its brief I know so I will follow-up in future with more detailed overview + how-to e.t.c either here or on the https://www.mycugc.org website in the experts area.

Upgrading to Citrix Workspace from Citrix Receiver for smart devices

In Closing
I work for Citrix, I have been a Citrix + IaaS advocate for well over a decade (now SD-WAN swell) so I am mostly likely bias you’ll think however Citrix Workspace app is truly AWESOME and way more than what you see at a glance, I encourage you all to begin consuming it today to see for yourself just what I am talking about and why I personally say its “AWESOME“.

Introduction to “Session Watermark”
The latest release of the XenApp & XenDesktop Service powered by Citrix Cloud or if you are performing a private cloud (on-premises) upgrade or net new installation of XenApp & XenDesktop 7.17 has some NEW features (another post brewing) and one that I have been waiting on for quiet sometime now has not finally arrived (WAHOO!) and its VERY VERY simple to configure and aids in improving your security posture (I believe) for delivery of apps & desktops powered by Citrix against e.g IP theft. In the below tweet can you see it?

The above is from my initial tests using a Windows Server 2016 VM hosted in Azure Northern Europe region running the 7.17 VDA configured to my Citrite #CitrixCloud XenApp & XenDesktop Service so I did not need to upgrade anything to get this new SHINY cool feature yes I said it SHINY. All I was required to do was deploy a new Windows Server 2016 VM from the Azure marketplace, domain join it, install the VDA and connect it to my Cloud Connector and I was ready in less than 25 minutes from initially deploying the VM from the marketplace.

Finally on a personal note for me Citrix SysAdmins enabling the “Session Watermark” feature obviously initally tested in a safe environment e.g UAT with a few users from a couple of departments and then rolling it out into production (as when/how your ready) will be making IT the modern “App & Desktop Security Heroes“. IT can apply and configure these new policies to be the most right vs. relevant for your organisations security needs while not hindering the end-users Rich HD eXperience.

Session Watermark Policies
You have 8 watermarking policies to apply with the 9th one enabling this security capability or feature set with the following list of quirks, suggested policy configuration and more available at – https://docs.citrix.com/en-us/xenapp-and-xendesktop/current-release/policies/reference/ica-policy-settings/session-watermark-policy-setting.html.

Before we get started it is worth mentioning that this feature does add an overhead to the compute on the backend (VDA side) and therefore it is suggested to enable up to two water marking features or items. In my overview of this feature I will wont cover off the cost of implementing this security policy as there are multiple variables to consider e.g HDX Graphics Mode and associated policies to provide the right vs. relevant end-user experience vs. how many watermark items do I apply? I have begun testing so bare with me and I’ll publish my findings either on my personal blog here or on https://www.mycugc.org under the “Expert Insights” area.

Enable session watermark
By default this feature is DISABLED as the default behaviour which I believe is the right approach considering its Citrix’s initial release of this #security feature (in my personal view) and secondly online documentation at eDocs suggested recommendations it to enable NOT more than two watermark text items. Finally * indicates that this policy is DISABLED by default when Session Watermark is enabled.

Include client IP address
* This is the IP addr of the device connecting to the virtual app & desktop.

Include connection time
* Utilises the following format yyyy/mm/dd hh:mm to display the users initial connection time to there virtual app or desktop.

Include logon user name
ENABLED by default when you enable Session Watermark as a policy and uses the following format USERNAME@DOMAINNAME is most optimise for 20 characters or less otherwise truncation might occur of the users logon username.

Include VDA host name
ENABLED by default when you enable Session Watermark as a policy and provides the VDA hostname e.g ne1vad01

Include VDA IP address
* Provides the internal IP addr that corresponding the VDA’s hostname e.g ne1vad01 = 10.1.0.7

Session watermark style
ENABLED by default using “Multiple e.g displays five watermark labels” when you enable Session Watermark as a policy or you can configure “Single e.g displays a single watermark label in the centre of the session“. TIP switching to SINGLE and sticking to two watermark text items for me in my initial tests is a good starting policy however time will tell as I continue to test out this new feature and its capabilities with different HDX Graphics Modes and associated tweaks.

Watermark custom text
* A unicode maximum of 25 characters is supported if you exceed this limit it will be truncated.

Watermark transparency
ENABLED by default set to “17 out of 100” when you enable Session Watermark as a policy, personally I think setting it to just 1 is fine in my initial tests as you want it to be not so in your face to the end-users to be bluntly honest.

What’s New with HDX (3D Pro) Technologies in XenApp & XenDesktop 7.16

Introduction what is HDX?
High Definition eXperience (HDX) is a set of technologies that provides a near to HD local like experience of a remoted virtual app, desktop or both to users anywhere in the world on any device even without installing anything on that device all you need is a modern widely used (supported) HTML5 compliant internet browser e.g Chrome, Safari (try it on your iOS devices :-)), Firefox, Internet Explorer you get the picture.

HDX is simple yet so powerful and has three founding principles which are intelligent redirection, adaptive compression, and data de-duplication like wise it has three principles it performs when you connect to there virtual resources which is Inspect the VM (Server vs. Desktop) what does it have e.g vGPU, Inspect the network what its like and can I use UDP for adaptive transport or should I fallback to TCP to remote the display + multimedia and finally it inspects the end-point what is there and can I use it? An example is the HDX Optimisation Pack available to offload audio/video for my Skype for Business sessions or shall I utilise generic HDX fallbacks?

I’m not going in great detail in this introduction so if your new to HDX or even an HDX Xen Master I’d still encourage you read the white paper published by Citrix on HDX Technologies at –
https://www.citrix.com/content/dam/citrix/en_us/documents/white-paper/citrix-hdx-technologies.pdf. Also be sure to check out the HDX resources page on Citrix.com at – https://www.citrix.co.uk/products/xenapp-xendesktop/hdx-technologies.html.

Finally you can find all the latest about XAD 7.16 and not just whats new with HDX in this release at – https://docs.citrix.com/en-us/xenapp-and-xendesktop/current-release/whats-new.html and you’ll notice that it’s not a 7.16 URL but refers to current release or CR.

HDX RealTime
Skype for Business to Teams “We are committed…” read all about it in Dereks blog post on Citrix.com – https://www.citrix.com/blogs/2017/11/08/the-big-news-about-microsoft-teams. The big announcement is that HDX RealTime Optimisation Pack now has an LTSR release version 2.4 which is available and you can learn more product lifecycle information at – https://docs.citrix.com/en-us/hdx-optimization/2-4-ltsr.html. Its also worth noting that this LTSR does NOT support any version of Microsofts Teams only Skype for Business 2015, 2016 you can learn more by reviewing the System Requirements for the client vs. server side at – https://docs.citrix.com/en-us/hdx-optimization/2-4-ltsr/system-requirements.html.

– HDX RealTime Media Engine for the Citrix Ready workspace hub (formerly known as HDX Ready Pi) is only supported for ViewSonic – https://citrixready.citrix.com/viewsonic/viewsonic-sc-t25.html or NComputing – https://citrixready.citrix.com/ncomputing/ncomputing-rx-hdx-thin-client.html Pi’s only. You can also get management of these devices from Stratodesk check out – https://www.stratodesk.com/products/raspberry-pi-thin-client.
– Behavioural changes in the way audio is handled in fallback mode when CPU is busy is to disable Echo Cancellation via the RTME as the generic HDX RealTime will handle this capability until returning to expected behaviour and lower CPU load.
– Enhancements to the microphone to provide better insights into whom is speaking.

The full list of what’s new in this LTSR is available at – https://docs.citrix.com/en-us/hdx-optimization/2-4-ltsr/whats-new.html.

HDX Broadcast
– The release of XAD 7.16 introduces a great new VDA installation behaviour change 🙂 whereby it will automatic set the HDX mode to be standard (Server OS) vs. HDX 3DPro mode (Desktop OS if it meets the requirements for HDX 3DPro e.g the Desktop OS includes a vGPU or GPU) which I believe is setup in the right direction and simplifying overall CTX Admin overhead e.g another syntax option to remember vs. I forget to configure the correct parameter.
– Now by default the new HDX Graphics mode is enabled is adaptive transport or EDT and is set to Preferred. Don’t worry if your a Citrix Admin as you’ve maybe already realised I didn’t enable UDP for this to work! Remember is an adaptive remote display protocol so it will fallback to TCP by default using the default Citrix HDX ports. Its also worth mentioning that when (Preferred) is set then SR is enabled for both UDP vs. TCP connections and client connections (Receiver check supported versions e.g Win min 4.10; Mac 12.8) are attempted in parallel during the initial connection, for SR reconnections and finally auto client reconnects aswell.
– Browser Content Redirection – https://docs.citrix.com/en-us/xenapp-and-xendesktop/current-release/multimedia/browser-content-redirection.html redirects the contents to the local device running an embedded browser within the HDX session which allows for offloading of content, network traffic, graphics from the VDA running in the resource location to the users end-point enhancing the UX significantly.
– Not strictly something new but HTML5 Redirection – https://docs.citrix.com/en-us/xenapp-and-xendesktop/current-release/policies/reference/ica-policy-settings/multimedia-policy-settings.html which is still currently only available for internal usage as you’ll read from the eDocs article but this is 100% something an Citrix Admin & Architects should begin testing today as HTML5 begins in my personal view to supersede Flash based websites as we move forward towards 2020.
– Auto DI Scaling for Multi-Monitor
– H.265 encoding support running on the latest end-points which supported a GPU that supports H.265 decoding and if its not available it will by default fall-back to H.264 decoding. The net result of moving to H.265 from H.264 which is a Platinum only feature results in significant bandwidth savings and much better UX. I have seen the net results with a few of our engineering customers that develop vehicles with teams spread out across the world and the results as awesome!
– Strictly speaking this is not agnostic or exclusive to the HDX technology stack but the Windows Continuum is quiet important for a great user experience and its powered by primarily at a the hypervisor level and its currently only supported on Citrix XenServer. Visit – https://docs.citrix.com/en-us/xenapp-and-xendesktop/current-release/technical-overview/hdx.html for how-to configure it today if your running XenServer.

– High definition webcam streaming for Windows Server with resolutions up to 1920×1080 – https://docs.citrix.com/en-us/xenapp-and-xendesktop/current-release/technical-overview/hdx.html#hd-webcam
– “Session Watermark” with custom text which you learn to setup and configure using the following CTX article – https://support.citrix.com/article/CTX230054 and was originally part of the XenApp Secure Browser and its deployment guide is available at – https://docs.citrix.com/content/dam/docs/en-us/workspace-cloud/downloads/Secure%20Browser%20-%20Deployment%20Guide.pdf.

In Closing
I be covering off some HDX topics in more detail in up and coming blog posts either here or in “Expert Insights” at myCUGC website at – https://www.mycugc.org/. Finally if you want to take part in my challenge for 2018 you can learn more about it at – https://www.mycugc.org/blog/a-2018-challenge-for-the-mycugc-community.

What is the difference between LTSR vs. CR for XenApp & XenDesktop 7.x?
The Long Term Service Release (LTSR) program for XenApp and XenDesktop provides stability and long-term support for XenApp/XenDesktop releases while the Current Release (CR) provides customers with the very latest version of XenApp and XenDesktop which includes the latest innovations e.g EDT v2

XenApp & XenDesktop 7.15 LTSR Feature Summary Comparison with 7.6 LTSR
The following is a simple one PDF page document that lists all the feature capabilities from initial first LTSR which was XenApp & XenDesktop 7.6 Feature Pack (FP) 1-3 through to the current LTSR XAD 7.15 including the CR releases in-between so its absolutely worth booking marking in your browser or better yet download it to keep it to hand for customer conversations – https://www.citrix.com/content/dam/citrix/en_us/documents/data-sheet/xenapp-xendesktop-715-ltsr-feature-summary-comparison-to-76-ltsr.pdf.

Noteworthy Points What’s New vs. Excluded
I’d very strongly recommend that your read the following CTX article – https://support.citrix.com/article/CTX205549 entitled “CTX205549 FAQ: XenApp, XenDesktop, and XenServer Servicing Options (LTSR)” and to ensure that you remain compliant post your update/migration to 7.15 LSTR you should download the “CTX209577 Citrix LTSR Assistanthttps://support.citrix.com/article/CTX209577

Its also worth noting the following that are classed as “Excluded Features/Components/OSes” from the XAD 7.15 LTSR but I’d like to stress PLEASE PLEASE refer for eDocs for full caveats vs. supporting statements at – https://docs.citrix.com/en-us/xenapp-and-xendesktop/7-15-ltsr/whats-new/7-15-ltsr-initial-release-.html+ and these listed notes are based upon the initial release however there is now a Cumulative Update 1 (CU1) already available so be sure to read through it as well at – https://docs.citrix.com/en-us/xenapp-and-xendesktop/7-15-ltsr/whats-new/cumulative-update-1.html.

OSes+
– Windows 2008 32-bit (for Universal Print Server)

Behavioural Changes
– Upgrading a XA 6.5 worker to a new 7.15 VDA is now slightly different and the detailed process is listed at – https://docs.citrix.com/en-us/xenapp-and-xendesktop/7-15-ltsr/upgrade-migrate/upgrade/upgrade-xenapp-6-5-to-vda.html and also be sure to review the XenApp 6.x Migration Tool at – https://docs.citrix.com/en-us/xenapp-and-xendesktop/7-15-ltsr/upgrade-migrate/xenapp-worker-upgrade.html and you review the migration tool by watching the embedded YouTube video below.

Finally while your planning your migration to XA 7.15 (FMA) from 6.5 (IMA) you will mostly likely be upgrading vs. migrating away from WIF so please be sure to read and how to migrate features to StoreFront from your WIF environment at – https://docs.citrix.com/en-us/storefront/3-12/migrate-wi-to-storefront.html. Equally I’d encourage any organisation reading this to review how-to setup and configure the “unified user experience” for Citrix Receiver vs. the Green Bubbles which will provide a much better experience for users you can enable it by quiet easily once you’ve read through the following article in eDocs at – https://docs.citrix.com/en-us/storefront/3-12/manage-citrix-receiver-for-web-site/unified-receiver-experience.html.
– Follow the supported leading best practises for upgrading the 7.15 LTSR by reviewing the following node within Citrix’s eDocs – https://docs.citrix.com/en-us/xenapp-and-xendesktop/7-15-ltsr/upgrade-migrate/upgrade.html
– VDA installation failures for Win 10 N Editions that don’t include Microsoft Media Foundation can now be acknowledged via the installation GUI of the VDA vs. automated deployed (unattended) there is a new option “/no_mediafoundation_ack“.

Excluded Features & Compoments+

What’s New
– Machine Catalog’s functional level within your Site from 7.9 do not require an upgrade
– Machine Creation Services (MSC) now supports generation 2 VMs with Microsoft System Center Virtual Machine Manager SCVMM
– The FMA or 7.x version of Local Host Cache (LHC) is now enabled by default BUT note that if it was disabled from a prior release of the XAD 7.x then you need to enable it and disable Connection Leasing (CL) https://docs.citrix.com/en-us/xenapp-and-xendesktop/7-9/manage-deployment/connection-leasing.html which was initially introduced into the 7.x platform to provide a fallback if your SQL database connection was lost or unavailable until LHC was re-introduced in XAD 7.12 – https://docs.citrix.com/en-us/xenapp-and-xendesktop/7-12/manage-deployment/local-host-cache.html but was not enabled by default in the 7.12 release CL was primarily utilised.
– Director App Failure Monitoring – https://docs.citrix.com/en-us/xenapp-and-xendesktop/7-15-ltsr/policies/reference/virtual-delivery-agent-policy-settings/monitoring-policy-settings.html#App_Failure_Policy_Settings

Security Leading Best Practises
– General Overview https://docs.citrix.com/en-us/xenapp-and-xendesktop/7-15-ltsr/secure/best-practices.html.
– Securing your StoreFront 3.12 environment – https://docs.citrix.com/en-us/storefront/3-12/secure.html
– Standardise on a single organisation user identity platform e.g AAD by leveraging NetScaler + + StoreFront + FAS which can convert SAML vs. OAuth tokens into virtual smartcards per configured Store within StoreFront to then SSO a user onto there intended virtual apps & desktops without requiring to re-enter his/her in a directory username + password for that resource location (What’s this? Read – https://docs.citrix.com/en-us/citrix-cloud/citrix-cloud-resource-locations.html).
– Slightly obvious to an Citrix expert vs. Citrix Partner but its worth highlighting for newbies to Citrix virtualisation technologies is that XAD management provides Delegated Administration to manage just enough access for different members of the IT vs. compliance departments/business units to have just enough access to complete there daily vs. weekly vs. monthly activities vs. tasks – https://docs.citrix.com/en-us/xenapp-and-xendesktop/7-15-ltsr/secure/delegated-administration.html and for remote secure access to virtual apps & desktops you will need implement NetScaler Unified Gateway – https://docs.citrix.com/en-us/xenapp-and-xendesktop/7-15-ltsr/secure/storefront-netscaler.html which can also enable and allow your organisation to control authentication at the edge of your network e.g 2FA vs. MFA vs. using Biometrics with supported 3rd Citrix Ready solutions so check out – https://citrixready.citrix.com. Finally you can also engage with SmartAccess capabilties when fronting XAD for R/A with NUG so check out the following resources for NS 11.x.n – https://docs.citrix.com/en-us/netscaler-gateway/11/integrate-web-interface-apps/ng-smartaccess-wrapper-con/ng-smartaccess-xd-config-con.html and NS 12.x.n – https://docs.citrix.com/en-us/netscaler-gateway/12/integrate-web-interface-apps/ng-smartaccess-wrapper-con/ng-smartaccess-xd-config-con.html and there is also a CTX article entitled “CTX227055 Smart Access Guide for NetScaler Gateway, StoreFront and XenDesktop” to review at – https://support.citrix.com/article/CTX227055 and finally you can configure Pre-Authentication scans to check that the connecting end-point is compliant (Refer to VDI Handbook section below).
Enabling TLS or Transport Layer Security for ICA/HDX Session – https://docs.citrix.com/en-us/xenapp-and-xendesktop/7-15-ltsr/secure/tls.html for a detailed how-to from the first LTSR check out the following blog article at – https://www.citrix.com/blogs/2014/12/11/how-to-secure-ica-connections-in-xenapp-and-xendesktop-7-6-using-ssl/ or download the white paper entitled “Citrix XenApp and XenDesktop 7.6 LTSR FIPS 140-2 Sample Deployments” from – https://www.citrix.com/content/dam/citrix/en_us/documents/about/citrix-xenapp-and-xendesktop-76-fips-140-2-sample-deployments.pdf. During some research I also came across the following CTX article to disable TLS 1.0 for XAD 7.6 LTSR which may or may not be useful to you check out – https://support.citrix.com/article/CTX215447.
– How do I assign the right vs. relevant security or UX policy? Refer to the built-in policy templates which you can read at – https://docs.citrix.com/en-us/xenapp-and-xendesktop/7-15-ltsr/policies/policies-templates.html which include the same policy type for modern vs. legacy OSes.

Citrix VDI Handbook for the 7.15 LTSR
Recommended pages of interest to read from “Citrix VDI Best Practices for XenApp and XenDesktop 7.15 LTSR” – https://docs.citrix.com/content/dam/docs/en-us/xenapp-xendesktop/7-15-ltsr/downloads/Citrix%20VDI%20Handbook%207.15%20LTSR.pdf which I am commonly asked about so I thought it makes sense with the current LTSR to list them out here for everyone to focus on what is right vs. relevant for PoC’s e.t.c

– Page 11 which focus on CCS Methodology
– Page 32 Five-Layer Design Model and Conceptual Architectures for XAD environments
– Page 35-37 Site topology covering latency, bandwidth vs. number of users
– Page 50-52 covers StoreFront keywords to the behaviour of the delivery of virtual resoucres
– Page 52 Scaling vs. sizing of your StoreFront cluster
– Page 54 Calculate what NetScaler required SSL through-put however i’d strong recommended engage with your Citrix rep for leading best practise vs. guidance as this can/may differ dependant upon your choose appliance vs. firmware version.
– Page 58 Implement GSLB with HDX Optimised routing to ensure connecting users in a regional vs. global deployment connect to better NUG by proximity.
– Page 63 HDX Display Protocol
– Page 66- User Profile types for Local, Roaming, Mandatory & Hybrid vs. virtual apps & desktop chooses model
– Page 79 Built-in Policy templates to optimise the UX based upon your organisational requirements
– Page 88-93 vCPU/RAM/Storage I/O vs. User workload types light, medium and heavy
– Page 94-97 SQL database sizing vs. scaling 5K up to 15K including expected database growth
– Page 98-99 PVS SQL database guidance for suggested sizing
– Page 104 XAD Controller sizing vs. scaling per 5K users which also includes a calculation
– Page 105 LHC considerations if enabled to re-size your control infrastructure for XAD
– Page 107 Citrix Cloud connector sizing for 5K users in private vs. public cloud
– Page 113-116 SQL Database sizing
– Page 121-129 PVS Accelerator with XenServer
– Page 132-140 Hardware Formulas for sizing vs. scaling including GPU(s)

Deploying a XAD 7.15 LSTR PoC
Coming…

What Citrix Receiver & HDX Optimisation Pack should I deploy?
You should consider reviewing and if fit for purpose for your organisation implement the Windows 4.9 LTSR Citrix Receiver version – https://docs.citrix.com/en-us/receiver/windows/4-9.html along with if you utilise Skype for Business for UC the LTSR of the HDX Optimisations Pack – https://docs.citrix.com/en-us/hdx-optimization/2-4-ltsr.html and you can find out more information about the lifecycle at – https://support.citrix.com/article/CTX200466.

Introduction
Its my 5th #CitrixSynergy and this is def one of the best Synergy’s I have ever had the privilege of watching virtually from London, England. Why not in person? I prefer to watch virtually as I am to consume more content faster and translate that into content to update Citrix partners/customers in a timely manner at high level and tech deep dive where required in particular areas or topics. Finally this blog post will most likely change over the next 2-3 weeks as I consume all of the Synergy 2017 content as when/how I can.
