Top 3 Features of Nutanix AOS 5.6

On April 16th, Nutanix released it's newest version of AOS (Acropolis Operating System). The 5.6 release has 9+ new features. But rather than cover them all, I wanted to call out what I consider the top 3 features of this release.

One or Two Node Deployment for Remote / Branch Office

Many businesses face the challenge of maintaining IT resources in remote locations. Whether it be a branch office or retail outlet, choosing the right solution to provide infrastructure which is easy to deploy and manage can prove difficult. Enter AOS 5.6. With this release, Nutanix now offers a single or dual node solution for ROBO deployment. The single node deployment can support up to 5 VMs, with disk level resiliency. The two node option supports up to 10 VMs and offers node level resiliency. Both options are managed centrally via Prism Central, allowing admins to administer the nodes alongside their on-premises data center. ROBO sites can also utilize cross hypervisor DR between the remote site and the DR location. And with all other Nutanix, the ROBO sites can be remotely upgraded using the same 1 click upgrades as the local site, saving the complexity of keeping a remote office up to date.

Microsegmentation hits GA

AHV users can now benefit from the GA release of Microsegmentation. Built into 5.6 and managed via Prism, application centric policy models can be deployed using a stateful distributed firewall. Single virtual machines or groups of VMs can all be protected, including blocking east/west traffic between them. Microsegmentation offers granular application isolation and zoning without configuring VLANs.

Volume Group Load Balancing of vDisks 

For users with high IO VMs, AOS 5.6 includes the ability for AHV to load balance vDisks in a volume group. CPU and memory resources are pulled from multiple CVMs (Controller VMs). This distribution across CVMs helps to improve the performance of the virtual machine and reduce bottlenecks.

Looking Through the (Cloud)Lens with Ixia

As data centers evolve, utilizing multiple cloud locations is becoming more common place. Whether its on-premises, hybrid cloud, or public cloud, monitoring this data is becoming a more difficult task. Cloud providers do not allow packet level inspection due to their architecture. Direct access to the hardware is prevented as well. Ixia looks to address these issues with their public cloud monitoring tool CloudLens.

Ixia CloudLens is a two part solution that offers end to end monitoring, down to the packet level, in multi cloud environments. CloudLens SaaS management pane runs in the cloud on  serverless architecture. The management portal is coupled with either a CloudLens Sensor Container, running on a Docker container, or CloudLens Sensor Agent for Windows based solutions. 

How Does CloudLens Work?

Starting with installation of the CloudLens Containers or agents, metadata about the cloud environment is collected. This data includes what cloud provider the sensor is running on, the resources being utilized by the instances, regions, and applications running on the instance. After this information is categorized by CloudLens, collection and tracking of relevant information will begin while disregarding unnecessary data. 

Configuring visibility into cloud traffic utilizes an easy 5 step workflow:
  • Identify source instances
  • Create source groups based on metadata
  • Identify tool instances
  • Create tool group based on metadata
  • Create secure visibility path from source to tools with intelligent filtering
In the above example, source groups are broken down into a typical 3 tier application use case, and the tool groups are the various methods utilized to monitor the health of the application.
Connections are made to each group utilizing drag and drop via the CloudLens Dashboard. This creates a secure peer to peer VPN connection. These connections can be one to one, or one to many. By utilizing groups, new instances created in the cloud are automatically detected and added to their corresponding group within CloudLens. No extra configuration is necessary, making scaling easy.

As the Ixia CloudLens is a container and SasS based model, the solution can be ran on AWS, Azure, GCP, IBM Bluemix, Alibaba Cloud, CentryLink, and the on-premises datacenter. Sensor agents and containers can be spun up in the in house datacenter and report back to the same dashboard as the public cloud solutions. Another benefit to the deployment model of CloudLens is that no additional security configuration is necessary. As the components live in the cloud environment, they ingest the existing security profiles.

One final benefit of CloudLens is container visibility. Docker container network namespaces map to the same host network namespace, but they operate independently to each other. This proves to be troublesome for traffic monitoring. By invoking the host namespace for the CloudLens Sensor namespace, the traffic can be easily monitored as it passes through the Docker host to the external network. The CloudLens Container namespace can also be configured to share the same namespace as the desired application. The "sidecar container" configuration allows for traffic monitoring of a single app given the shared network namespace. 

For more information on CloudLens, and other Ixia offerings, take a look at their Tech Field Day 15 Presentations, or visit Ixiacom.com

Riverbed Steel Fusion: A New Approach to Remote Office Infrastructure

Riverbed Steel Fusion: A New Approach to Remote Office Infrastructure  


Approaching the remote office/branch office (ROBO) deployment can be a more complicated task than it originally appears. Many vendors in this space offer a quick deployment, but fail to look deeper into the needs of the business to provide a well rounded solution. How does a business plan for disaster recovery at a remote site? What about offices in foreign countries? Data location and international laws could complicate the ability to protect intellectual property of the business. Enter Riverbed Steel Fusion. Steel Fusion offers administrators simplified ROBO deployments, centralized management, and provides options for problems that could be easily overlooked when planning for remote offices.   

What is the SteelFusion Solution?

SteelFusion is a Software-Defined Edge solution consisting of a two parts: Core and Edge. In the on-premises data center, the SteelFusion Core (a physical appliance or virtual machine) is connected to the SAN or NAS storage. It should be noted that the SteelFusion core can also be linked to AWS or Azure storage components for those with a multi-cloud solution. The SteelFusion Edge appliance is deployed at the remote site. Once the base network configuration is made, the appliance is remotely managed from the Core.

How does SteelFusion differentiate from other ROBO solutions?

SteelFusion separates itself from the pack by keeping corporate data housed in the main data center. With the data on-premises, planning for backup and disaster recovery is simplified to one site. No need to develop a complicated solution encompassing multiple remote offices. Similarly, since data lives in the SAN/NAS, it becomes less vulnerable to foreign data laws. The data required by the ROBO, whether it be files or VM disks, is replicated and cached to the Edge, and changes are written back to the SAN/NAS at the Core.

Aside from passing the data to the remote site, the Edge appliance can also replace traditional compute solutions with Riverbed’s Virtual Services Platform. VSP runs VMware ESXi to on the SteelFusion Edge appliance, eliminating the need for additional hardware.

On paper the solution seems solid, but does it hold up in the real world? The answer appears to be yes. Based on statistics provided by Riverbed in September of 2017, there are over 10,000 appliances deployed across 1,200 customers globally. From experience in my professional life, installation and management is easy. I have encountered a few enterprises in my area currently utilizing SteelFusion, or with plans to implement SteelFusion in 2018. While it may not be a perfect solution for every ROBO use case, SteelFusion is certainly worth investigating.

That's a Wrap: An ExploreVM Look Back at 2017

One word comes to mind as I sit here and look back at 2017 and the adventures I've had with the ExploreVM blog/podcast - Growth. I am thankful to be part of a great community that has provided new opportunities, new ventures, and new experiences. I haven't been nearly as productive on the blog/podcast front in November and December of last year due to some personal matters, getting slammed with work, and the holiday. So, let's kick off 2018 with a review of 2017, and a preview of things to come.

Community Recognition


For the second year in a row, I was privileged enough to be part of the VMware vExpert program. I often tell people that just because I am a "vExpert", it doesn't mean that I know everything about VMware. And man is that true when immersed in the vExpert Slack channels or conversating with vExperts at events. I've learned so much from fellow vExperts in the past year that I couldn't begin to thank everyone who's knowledge I've grown from.

I also took a crack at applying for another community program, and to my surprise I was accepted. I was named one of the 150 Nutanix Technology Champions for 2017. What I like about the NTC program is that it is smaller than similar groups which gives individuals a better experience. There are a great group of technologists in the NTC program which have helped me grow my skill set immensely since I joined. Angelo Luciani runs a great program at Nutanix!  

Blogging and Podcasting


As an accompaniment to the blog I've been running for four years, I dove into the world of podcasting. The first season of the ExploreVM podcast launched in February with15 episodes focusing on various topics in the datacenter realm. It's been great to follow the career journey of my guests after their appearance on the show.

In January I will begin recording episodes for Season 2, which I plan on kicking off in February. The goal is to publish an episode every two weeks. I'm looking for guests, so please do not hesitate to reach out on Twitter or drop me an email if you want to appear. I'd like to bring on some new voices and perspectives in the next season. Let's explore the datacenter world together!

On the blog front, 2017 marked my most productive year with 14 posts. The vExpert and Nutanix NTC program provided lots of great access to products and announcements, which in turn lead to numerous posts. With added posts, comes added readership as well. A bit of a humble brag, but ExploreVM.com saw a 325% increase in hits from EOY 2016 to EOY 2017. If everything I've got lined up works out as planned, including a new website design, 2018 should see the same growth!

As we look forward into 2018, I have several posts lined up as a result of Tech Field Day. As we go forward, I see the ExploreVM blog taking more of an analyst route.. However, that does not mean that my event recaps or technical posts are going away, they will just occur a bit less often. Diving into technologies, learning what makes them work, and figuring out where they fit in the datacenter world has become not only beneficial to my professional life, but a very enjoyable aspect of my writing.

I have also launched a YouTube channel which I will be publishing videos on various topics. I expect these videos will parallel some of the podcasts, or be informative similar to VMUG sessions. This will be a new venture for me into 2018, but all of my previous podcasts are available there currently for review.

One more thought on the content creation front. As growing the blog and podcast is starting to incur some costs, namely hosting, software, and recording equipment, I am considering doing some sponsored content. This would be done in lieu of running ads. I find sponsored content to be less intrusive than ads on sites and podcasts, and when done properly, the posts can have quality content. If your company or product would like to sponsor a post or episode, please email me, or message me on Twitter.

Speaking and Events


The core of my community involvement has always been attending and speaking at VMUG meetings, and 2017 was no different. This year I added Keynote Panel speaker to the resume on top of my usual community sessions. Indianapolis, Chicago, and Wisconsin VMUGs were all gracious enough to allow me to speak at their UserCon's this past year. I take so much joy in giving back to the community that has helped my career explode. 

If you have never spoken at a VMUG meeting, please consider doing so. Community generated content is always in demand. Many people out in the vCommunity, myself included, are more than willing to coach you on your session. Like I mentioned before, everyone has useful experience, don't be afraid to share. 

This year had two new speaking firsts. March led off with a pre-recorded webinar that was sponsored by Intel and Nutanix. The recording experience was a touch nerve racking as I had no idea how I looked or sounded until the webinar aired. That being said, I would absolutely do it again. Community involvement led to speaking at two conferences during the summer of 2017. 

My final event for 2017 was an invitation to Tech Field Day 15 in San Jose, California. What's unique about the TFD15 experience versus my other events for the year is that the delegates get to grill the vendors and learn about products rather than having to speak on a topic. We were either  brought to the offices of the vendor, or they came to our location, and we were granted access to everyone from engineers to CEOs. While I am slipping a bit in the timeliness department, look for blog posts about these vendors in the coming weeks. Outside of the Tech, I got to meet, chat with, and learn some amazing folks in our industry. They certainly lit a fire underneath me to do more with myself after spending just a few days in their company. 

Now, if you'll excuse me, I have to get on to writing other blog posts and working on the website redesign. One last bit of info, I've included some of my goals for 2018, as well as some blog and podcast stats for last year.
