Docker based Windows containers support for Windows Server and Azure

That’s it. Docker won over Windows containerization as well!

Microsoft just announced it will add to its support for Linux VMs running Docker Linux Containers, support of Docker engine inside Windows Server and Windows Azure, to support native Windows containers,

More info here: Docker based Windows containers

This means you will be able to develop and support your Windows Apps within a slim agile-to-maintain container. What happens to licensing is one question, and what happens to security is definitely another worthy question.

VMWorld 2014 – Cool stuff you should know about

Here are my VMWorld 2014 notes about the conference’s top new solutions.

Bottom line, I expect most of those features and solutions become popular and although it starts to feel like there is “too much”, that’s our role as IT Professionals, to pick the right tools for use in the right time and place.

  1. EVO: Rail – “Data Center in a Box” – allows hardware and software ISVs to package their multi-suite software appliances into a single kit that includes shrink-wrapped manageability options (no need for vCenter and similar management tools, but they can be used if you have them). All deployed within 15 minutes!
  2. EVO: Rack – “vHardware v2.0“. Yes, “vHardware” is my term to describe the offering of integrated, data center scale hardware to support quick deployment of VMware at mass scale. In the past years it featured products such as Cisco UCS, EMC vBlock, NetAPP FlexPod). I’d say EVO: Rack is the second “vHardware” major effort, now fueled by the new “SDDC” (Software Defined Data Center) standard, including extensible racks including servers, storage, networking (from various hardware vendors) and the complete suite of VMware’s data center management products, all deployable within 2 hours and aimed to allow launching multiple Virtual Data Centers, within a single physical Data Center.
  3. vCloud AirAllows for easy transparent secure migration of VMs into and from the cloud, or across the world into and from other data centers. The policies, including network and security rules of a VM will migrate with it, and be enforced, no matter where it is migrated to. All based on the new vSphere 6.0 (Beta) engine.
  4. vCloud Realize – Management and monitoring of Operations,  Automation, Business, provided on internal external or Hybrid Cloud via vCloud Air.
  5. Contributing to and integrating with Docker containers as well as with Google Kubernetes Docker management software, both are becoming a strong standard for agile development, testing, packaging and deploying software. Essentially you can deploy and maintain Docker containers within the well-known VMware management tools, such as VMware vCenter.
  6. Pay as You Go – packaging of VMware’s products as SaaS or IaaS (some now, others in the future). That’s cool and not trivial for solutions that are dealing with infrastructure.
  7. vSphere 6 Beta now allows migration of live VMs from one GEO location to another one across the world, providing transparent network access to the VMs without any adjustment of their IP network details independently of the actual local network details for each GEO location, all based on VMware NSX technology)
  8. Policy based deployment and enforcement of SDDC: network, storage, availability, etc. Those policies automate the setup and maintenance of our VMs, and reduces the need to create and monitor operation and monitoring related scripts.
  9. Virtual Volumes (Beta): Using the Sphere APIs for Storage Awareness (VASA), it allows for the offloading of VM operations to the most common storage solutions. For example, creating a VM snapshot can be done by the storage system (EMC, NETAPP, etc), using its own means to do what until now, the VMware ESX server had to do. This complements past offering of VMware’s Virtual SAN, which aimed to replace the need for expensive physical storage solutions, by offering many of the SAN storage features through software on top of economic commodity hardware.
  10. Rapid mobile deployment of apps (temporary desktop) streamed from VMware cloud assisted by the Air-Watch technology. As an example, allows one to send a document that requires a specific APP, to another person. If the receiving party is entitled to use the relevant app, it will be available for him as soon as he tries to open that document.
  11. Federated App / Desktop Delivery via VMware AirWatch. As an example this allows a doctor to securely send a patient health test result to another expert’s mobile device, even though the expert works in another hospital. Only the doctor and the expert can collaborate on this document. All done seamlessly. App delivery and usage is streamed through VMware cloud data centers in the background so it seems delivery is instant.

That’s it for now.

Do let me know what you found out so far (I am still going through the VMWorld Brown Bag sessions).

Docker containers to rock CoreOS

Check out the “Docker” new slim Linux containers technology, now at the center of CoreOS

CoreOS is an easily scalable SaaS / MSP targeted Linux variant, now available on Google Compute engine as well.

Each Docker container includes a complete App / Service with all its Data Structures, similar to Ca Technology 3Tera.

May the Power(CLI) be with you! (PowerCLI Book Review)

Remember the famous line Yoda tells Sky Walker in the first “Star Wars” movie? He says “May the Force Be With You!”

For years I have traded it with “May the cursor be with you”.

Recently since I had a crash on PowerCLI and then on PowerShell, I started looking for good books on PowerCLI.

The first one I found was dated 2011, so it was good, but not good enough.

Then I saw on twitter Robert van den Nieuwendijk was looking for reviewers for his new “Learning PowerCLI” book.

Learning PowerCLI Book Review - Book

This was right on for me and I got free access to the book copy for review, within few hours.

I will be using it through my journey to get more intimate relations with our VMware operations. But I can say the quick “I need to” test came out with flying colors. I mean, you could read the book chapter by chapter, but you would also want to quickly find how to do something specific. In this case I was looking for Data Store latency information and within 5 minutes found the background materials as well as the specific commands.

Having a trusted guide (Robert), I also took on his warm advise to finally look into the automated comprehensive vCheck Script as well as the PowerGUI tool and wonderful set of ready to use packs (more on this on a separate post). One word of caution – I would not use just any library pack offered there, before I take a look at the author and the scripts, and I always run them under a user with read-only permissions, preferring a quick test on a test environment first, just to quickly see it actually works.

This resulted in a quick report I was able to construct within an hour, showing a possible savings of ~ $15,071.

For now I think I’d replace Yoda’s blessing with “May the Power(CLI) be with you” 🙂

More on my review of the book soon…

P.S.

What are your favorite Power CLI resources?

VMware vSphere 5.5 cool new features

Here is my pick of the VMware vSphere 5.5 cool new features:

1. Support of ~52 TB on a single vmdk allows big storage VMs, closer to real server capacities
2. The vCenter appliance now supports up to 100 hosts and 3000 VMs with the internal DB takes it into SMB plus size or moderate Development shops level
3. Official support of latest 4 virtual hardware versions reduce the need to upgrade VMware tools component, when new vSphere version ships, hence less reboots for VMs
4. Utilizing better reliable memory section in a hardware, leverages the protection for the more critical parts of the ESX hypervisor. This adds to the overall stability of the virtual VMware based data center.
5.latency issues in the hypervisor are addressed in new, easy to configure settings.
6. vSAN (beta) included in the core vSphere aiming to address the massive need for low-cost storage for VDI deployments. It allows defining VM storage needs in terms of speed, reliability, caching, raid level and other operational factors. vSAN then dynamically assigns the VM resources off the storage pools it had found avail with those capabilities. vSAN turns any local disk on any commodity ESX hardware into a part of the aggregate vSAN based datastore.

P.S

Here are some VMware vSphere 5.1 Cool features I did not have time to post about until now…They are still great!

Voma – VMFS on disk meta data analyzer finally! Checks for file system errors but does not fix them yet

New sparse disk efficient can reclaim unused guest (!!) disk space – Only for sc sparse disks and VMware View machines

Storage I/O control turned on by default to get more I/O info about VMs and assist storage DRS mechanism

You now get SSO (Single Sign On) server which you can hook to multiple Microsoft Active Directory domains as well as vCenter servers. Once you authenticate, the SSO server provides your VI Client with a certificate, it can later use to authenticate all the VMware v5.1 solutions

That’s the last time vi Client has a non web version

The new web client option has a new ‘pause’ feature allowing you stop a wizard walk through saving its data and state to continue later on as you do other actions first. Very nice time saver!

Third party plugins need update to fit the new server-based / web GUI client

That’s it for now folks! What features did you like the best?
