OpenStack and Nutanix – perfect match! (perfect with VMware and Microsoft as well of course) – #Nutanix, #OpenStack, #IaaS

This is a good post by Dwayne Lessner around how perfect match OpenStack and Nutanix is (not just OpenStack of course, Nutanix rocks with VMware and Microsoft as well)!

Nutanix NDFS also provides an advanced and unique feature set for OpenStack based
private clouds. Key features include:

  • Simplicity – The same great platform that simplified your virtualisation deployment can simplify the compute and storage deployment for key OpenStack services (Glance, Nova, Horizon, Keystone, Neutron, Cinder, and Swift)
  • Single Scalable Fabric – NDFS provides a single fabric for data storage that integrates seamlessly with OpenStack services. NDFS-based storage is easy to provision, manage, and operate at scale.
  • Hypervisor Agnostic – Just like OpenStack, Nutanix NDFS was designed from the ground up to be hypervisor agnostic. Nutanix enables customers to choose between KVM, Hyper-V, and the VMware ESXi hypervisor for deployments of OpenStack.
  • Enterprise Ready – Nutanix enables a full set of enterprise storage features including Elastic Deduplication, Compression, In-Memory and Flash-based Caching, VM-Data Locality, intelligent Information Lifecycle Management (ILM), Snapshots, Fast Clones, and Live Migration.

#Gartner analyst slams #OpenStack, again – #IaaS

November 22, 2013 Leave a comment

Good article and I must agree that OpenStack has quite a long way to go before the “average” enterprise embraces it…

OpenStack still has maturing to do before it’s really ready for the enterprise, analyst says

Network World – Gartner analyst Allessandro Perilli recently attended his first summit for the open source cloud platform OpenStack and he says the project has a long way to go before it’s truly an enterprise-grade platform.

In a blog post reviewing his experience, the analyst – who focuses on studying cloud management tools – says that OpenStack is struggling to increase its enterprise adoption. Despite marketing efforts by vendors and favorable press, enterprise adoption remains in the very earliest stages, he says.

Don’t believe the hype generated by press and vendor marketing: OpenStack penetration in the large enterprise market is minimal.
— Gartner analyst Alessandro Perilli 

Sure there are examples like PayPal, eBay and Yahoo using OpenStack. But these are not the meat and potatoes types of enterprise customers that vendors are looking to serve. Why? He outlines four reasons, most of which are related to the process and community nature of the project, and less around the technical maturity of it. By the way, this is not the first time a Gartner analyst has thrown cold water on the project.  

[EARLIER CRITICISMS FROM GARTNER: Gartner report throws cold water on OpenStack hype]

Lack of clarity about what OpenStack does

There is market confusion about exactly what OpenStack is, he says. It is an open source platform that can be assembled together to build a cloud. It, by itself, is not a cloud though just by downloading and installing it. OpenStack requires some heavy lifting to turn the code into an executable cloud platform, which is why dozens of companies have come out with distributions or productized versions of OpenStack code. But, the code itself is not a competitor to cloud platforms offered by vendors like VMware, BMC, CA or others. Read more…

#Gartner report – How to Choose Between #Hyper-V and #vSphere – #IaaS

November 19, 2013 Leave a comment

The constant battle between the hypervisor and orchestration of  IaaS etc. is of course continuing! But it is really fun I must say that Microsoft is getting more and more mature with it’s offerings in this space, great job!

One of the things that I tend to think most of is the cost, scalability and flexibility of the infrastructure that we build and how we build it, I often see that we tend to do what we’ve done for so many years now. We buy our SAN/NAS storage, we buy our servers but lean towards Blade servers though we think that’s the latest and coolest, and then we try to squeeze that into some sort of POD/FlexPods/UCS or whatever we like to call it to find our optimal “volume of Compute, Network and Storage” that we can scale. But is this scalable like the bigger cloud players like Google, Amazon etc.? Is this 2013 state of the art? I think that we’re just fooling ourselves a bit and build whatever we’ve done for all these years and don’t really provide the business with anything new… but that’s my view… I know what I’d look at and most of you that have read my earlier blog posts know that I love the way of scaling out and doing more like the big players using something like Nutanix and ensure that you choose the right IaaS components as a part of that stack, as well as the orchestration layer (OpenStack, System Center, CloudStack, Cloud Platform or whatever you prefer after you’ve done your homework).

Back to the topic a bit, I’d say that the hypervisor is of no importance anymore, that’s why everyone if giving it away for free or to the open source community! Vendors are after the more IaaS/PaaS orchestration layer and get into that because if they get that business then they have nested their way into your business processes, that’s where ultimately that will deliver the value as IT services in an automated way once you’ve got your business services and processes in place, and then it’s harder to make a change and they will live fat and happy on you for some years to come! 😉

How to pick virtualization (HW, NW, Storage) solution for your #VDI environment? – #Nutanix, @StevenPoitras

September 13, 2013 Leave a comment

Here we are again… a lot of companies and Solution Architects are scratching their heads thinking about how we’re going to do it “this time”.

Most of you out there have something today, probably running XenApp on your VMware or XenServer hypervisor with a FC SAN or something, perhaps provisioned using PVS or just managed individually. There is also most likely a “problem” with talking to the Storage team that manage the storage service for the IaaS service that isn’t built for the type of workloads that XenApp and XenDesktop (VDI) requires.

So how are you going to do it this time? Are you going to challenge the Storage and Server/IaaS service and be innovative and review the new cooler products and capabilities that now exists out there? They are totally changing the way that we build Virtual Cloud Computing solutions where; business agility, simplicity, cost savings, performance and simple scale out is important!

There is no one solution for everything… but I’m getting more and more impressed by some of the “new” players on the market when it comes to providing simple and yet so powerful and performing Virtual Cloud Computing products. One in particular is Nutanix that EnvokeIT has partnered with and they have a truly stunning product.

But as many have written in many great blog posts about choosing your storage solution for your VDI solution you truly need to understand what your service will require from the underlying dependency services. And is it really worth to do it the old way? You have your team that manages the IaaS service, and most of the times it just provides a way for ordering/provisioning VM’s, then the “VDI” team leverages that one using PVS or MCS. Some companies are not even where  they can order that VM as a service or provision it from the Image Provisioning (PVS/MCS) service, everything is manual and they call it a IaaS service… is it then a real IaaS service? My answer would be now… but let’s get back to the point I was trying to make!

This HW, Hypervisor, Network, Storage (and sometimes orchestrator) components are often managed by different teams. Each team are also most of the times not really up to date in terms of understanding what a Virtualization/VDI service will require from them and their components. They are very competent in understanding the traditional workload of running a web server VM or similar, but not really dealing with boot storms from hundreds to thousands of VDI’s booting up, people logging in at the same time and the whole pattern of IOPS that is generated in these VM’s “life-cycle”.

This is where I’d suggest everyone to challenge their traditional view on building Virtualization and Storage services for running Hosted Shared Desktop (XenApp/RDS) and Hosted Virtual Desktop (VDI/XenDesktop) on!

You can reduce the complexity, reduce your operational costs and integrate Nutanix as a real power compute part of your internal/private cloud service!

One thing that also is kind of cool is the integration possibilities of the Nutanix product with OpenStack and other cloud management products through its REST API’s.  And it supports running both Hyper-V, VMware ESXi and KVM as hypervisors in this lovely bundled product.

If you want the nitty gritty details about this product I highly recommend that you read the Nutanix Bible post by Steven Poitras here.

Top 5 #Citrix #XenServer Questions from the Citrix Master Class

February 27, 2013 Leave a comment

Below are the top 5 XenServer questions raised from the Citrix Master Class posted by Amanda Saunders!

Let’s face it, XenServer has been around for quite a while. Citrix purchased the hypervisor back in 2007 and released it entirely free to the market in 2009. Since then, we’ve seen over 1 million downloads of the product and mass adoption in all sorts of businesses from SMBs to the largest service providers. Despite all this, we had almost 700 first time attendees on our XenServer Master Class last week taking a look at what this product has to offer. The newbies were joined by 300 additional Master Class veterans who continue to return to see what we’ll be showing off this time on our British radio show inspired, tech webinar. All of the attendees joined in to keep us busy, asking hundreds of questions for our XenServer experts to answer live on the webinar. If you missed it, watch the recording and read a summary of the top questions asked by the audience.

Why are cloud providers choosing XenServer to power their clouds?

This question could have an entire blog post dedicated to it, but I will try to address it as simply as possible. Currently 80% of Citrix CloudPlatform and Apache CloudStack environments are built on top of Xen or XenServer. Why? The high level reasons are scalability and cost*.

Scalability comes from XenServer’s fully replicated architecture across all hosts in an environment. This means there is no management server required to manage a given number of hosts. Should the master host in a pool go down, any other host can be promoted to replace it with no loss of functionality or configuration. In practice, this means cloud providers can freely choose to cluster hosts as required without incurring any additional configuration or management complexity based on cluster size.

While cost is an important factor for every company to consider, it is particularly important when you’re looking at licensing hundreds or even thousands of hosts. Both the open source version of XenServer and the premium version of XenServer that is included as part of your CloudPlatform entitlement, mean cloud providers can get the virtualization layer of their cloud at no cost. These savings can then be turned into additional differentiated service offerings or added savings to their end user.

 *other reasons include open source base, flexibility, VM density and tenant isolation.

XenMotion, what is it and is it free?

We have a competitor in the space who likes to use “v” in a lot of their feature names. A good rule of thumb to find the corresponding feature in XenServer is to replace “v” with “Xen”. XenMotion is our live migration feature that allows you to move VMs from one host in a pool to another provided that the pool has shared storage attached. This has been available in our free version since 2009.

Storage XenMotion is a brand new feature that we released with XenServer 6.1. This feature enables you to move VMs between hosts without the requirement of shared storage which lessens the hardware requirement/expense for both cloud providers using commodity hardware and SMBs with smaller environments. Storage XenMotion is available in our advanced version of XenServer.

Is there an easy way to get support for my environment, even if I’m running on free?

For those of you running a premium edition of XenServer (Advanced, Enterprise and Platinum) we recently changed our support model to offer unlimited, 24×7 support for paid editions of XenServer at about 7% of license cost. What does this mean to the free users out there? Well, it means you can no longer purchase support from Citrix for your XenServer environment. That being said, in addition to the incredible support you can get on the forums, we’ve also introduced a new Citrix Auto Support tool that can do a sanity check of your environment. Simply upload a log file and we’ll check for any issues that we recognize including missing patches, known bugs or configuration errors. This tool can be used for both free or paid editions, so try it out for yourself at http://taas.citrix.com.

What is MonitorIT?

A big thank you to our friends at Goliath Technologies who demoed their brand new version of MonitorIT on our XenServer Master Class. This solution delivers proactive monitoring of your entire environment right out of XenCenter or directly from a browser. What do we mean by “entire environment”? Virtual servers, physical servers, VDI, applications, databases, log management, network, storage, data center components, workstations – EVERYTHING! Do you have multiple hypervisors in your environment? Monitor your vSphere clusters straight from your XenCenter console using this product. You can go one step further and have MonitorIT proactively make changes to alleviate bottlenecks in your environment so the business can keep doing business without interruption. Don’t take my word for it, check out their free trial for yourself. They’ve even opened up their early access program so you can access all the great new features that…
