Why #Webscale Reason 5: Brain Drain, Training Budgets & Turnkey Solutions

Companies like Google, Amazon and Facebook had to invent (code) new technologies and approaches to doing IT because no alternative to traditional IT existed. Lots of the technologies surrounding this can be complicated and does take a highly trained team to forge ahead. Web-scale is not an all-or-nothing proposition. Today we’ve reached a point where the principles and patterns are well-understood and turnkey enterprise-class solutions are emerging to bring web-scale capabilities to the enterprise. These don’t require PhDs to operate. Even some of the industry storage giants like EMC are trying to deploy similar technologies to provide true scale out technologies. Nutanix has been building upon these technologies since 2009 so people can do more with less. An IT Admin has the option of never leaving the Prism UI if they want.

Like it or not, enterprise IT is fighting with the cloud for relevance. Enterprise IT is not that way by choice. The politics and finger-pointing is what traditional infrastructure constraints and complexity have created. Budget constraints are all the more reason why you need an alternative. If you have the opportunity to learn one skill to save countless hours down the road is that not a fair price to pay? I remember an old boss questioning my VMware 3.0 training over the same things. Do I need it? Is it valuable? Many of the skills that were considered niche 5 years ago are now mainstream. Companies like Nutanix are eliminating the need for specialized talent by delivering turnkey solutions that are web-scale inside but provide enterprise capabilities, offering the best of both worlds.

The reason why VMware SRM was invited was so people could get out of the weeds of scripting and engineering their DR plans. When people changed jobs or left the company you wouldn’t have to be worried about the next lady/man stepping into fill their shoes and figure the failover process if a disaster were to occur.

With any new technology or paradigm shift there needs to be a way to bridge the gap between the two worlds. The difference between Public vs Private cloud in this case is learning a UI and hiding the complexity. Virtualization is a key aspect to Nutanix so a lot skills will work in the old and the new land of the datacenter.

Why #Webscale Reason #4: Machine Data & Analytics #Nutanix #Linkedin

When you open up your infrastructure up to API’s and have a platform to automate all aspects it allows a common management and analytic platform. Silo’s of infrastructure not only put additional strain not only for storage performance with the IO blender effect but also managing the wealth of data that is generated. Google’s ability to collect and analyze has changed the game for them. Having different hardware, different data centers and different use cases to contend with, it’s all about managing the whole story and seeing problems before they end up on your CIO’s dashboard. This can really only be with a shared nothing architecture.

Look at how LinkedIn is doing it. Similar aspects to the Nutanix design.

Why #Webscale Reason #3: It’s about the people – #Twitter #APIgee #DataStax #Nutanix

It’s not all about wing dings and nuts & bolts. It’s easy to get lost in the weeds of technology and forget the greater purpose of why a IT department exists. When technology religion starts to dictate what is right for business it can easily turn into a dead end street. People and process are the hardest things inside of tech and where web-scale plays a part. Web-scale is about launch first, optimize later. Focusing what you’re good at and getting to the last 10% can be iterative process. It’s not about speeds and feeds, it’s about getting your teams to focus on the business and work together. It’s breaking down tradtional silos and helping move the needle. I believe the general sysadmin will have a long life ahead of them versus people that are totally focused in one area.

At Nutanix we have no religion on hardware. Today we OEM through Super Micro, tomorrow we could switch if the economics made sense, performance and form factor made sense.

Launch first has allowed Nutanix to get to MapReduce Dedupe (Post-Process) probably in one of the quickest fashions. It started with inline dedupe for performance, it was put into production and built upon work from out Medusa/Cassadonra team. Then MapReduce Dedupe came focusing on OS and application data. Over time more algorithms will be added to MapReduce Dedupe which will potentially lead to more features.

From a customer perspective launch first gives you more options to make a better descsion. This is another reason why hybrid cloud will succeed.

Why #Webscale Reason #2: System Design #Nutanix

Keeping things up to date in the Enterprise usually happens when a support contract is about to run out or when a new feature is needed. Teams are reluctant to make changes when outages need to be planned, load on the systems needs to low and possible manual intervention is needed throughput the process.

Web-Scale allows non-disruptive rolling upgrades, no single point of failure and minimal intervention. Self-defining (and versioned) disk format, like protobufs This way, upgrades of disk data can be done lazily. Web-scale can’t assume 1-shot data upgrades, given the scale that it could consume. This also inherently allows client/servers relationship to be a different versions throughout the process which is a pretty big accomplishment onto itself.

Why #Webscale Reason #1: The swipe card effect #Nutanix

Web-scale IT is making its way into the mainstream enterprise datacenter. In support of a joint event that Nutanix is supporting I will give my reasons why web scale is becoming common place.

Reason 1:

swipeClients\customers leave to public service providers when their needs aren’t be meet fast enough. Enterprise IT has lots of complexity and silos arounds networking, storage and compute which results in unpredictability with scaling out current environments. Do you have enough throughput available to add your next storage array? Do I have ports left on my fiber channel switch to add my next server? At the end of the day the business doesn’t care how this achieved. Adding storage or compute should be a non-event. It’s all about delivering services. Shrink or grow, 1 node, or 20 nodes it needs to happen at the pace of business.

On June 25th, Nutanix is celebrating web-scale IT with Web-Scale Wednesday, a live online event that will bring together IT leaders, industry experts and enterprise customers to share their perspectives and experiences adopting web-scale IT and bringing it to the enterprise. Speakers from Twitter, DataStax, Dell, Citrix and more across the industry. Join us

Loginvsi and the Launchers from Hell

Just from friendly advice from a guy who has been hunting down bugs and to remember a healthy launcher is just as important as great golden image.

1) Remove the Windows XPS printer so you don’t have to worry about printer redirection issues.

2) vSphere 5.5 and VMware tools has issues and can reset the network. Easiest thing to do is disable logging for VMware tools.

3) Installing Citrix receiver installs some older version of c++ 2005 libraries and you’ll see a ton of sidebyside in the event logs. Install by the X86 and X64 of the SP1 and you’ll be good to go.

4) More VMware tools issues – Unity (Mac) showing up in the logs, KB here to fix

5) Stick to the recommendations when using connectors of your broker of choice. If you need a lot of launchers here is PowerShell script that will help you along -> http://vmwarepro.wordpress.com/2012/05/19/provision-multiple-vms-from-template-via-powercli/

or a great tip from @shanetech is to use PVS for the launchers.
