[EN] OpenStack remains difficult to implementBen Kepes
OpenStack has been something of a divisive topic since its inception a handful of years ago. Initially conceived as a cloud operating system that would allow service providers and large enterprise to build their own versions of Amazon Web Services, OpenStack's focus has changed somewhat in the years since, as it has tried to find a good fit. At the same time, huge amounts of money have been poured into the OpenStack ecosystem, with a plethora of startups being formed and funded to commercialize the OpenStack opportunity. It has to be said that, as it currently stands, the commercial returns from these investments haven't been awesome.
That's not to say that OpenStack isn't proving successful in the marketplace; indeed, the OpenStack Foundation, the organization with the unenviable task of balancing the not-inconsiderable conflicts that naturally occur when commercial entities are trying their hardest to achieve commercial success off the back of a communal effort, spends lots of time and effort regaling all-comers of the success of OpenStack at its regular summits. Having attended a number of these summits, I can vouch for the real-world organizations that are using OpenStack to run critical workloads.
But a regular refrain I hear from OpenStack users, and one that is backed up by the fact that perhaps the most successful OpenStack startup, Mirantis, is firmly focused on being a service provider helping companies deploy the system, is that OpenStack is just a little bit hard to use. A new survey commissioned by SUSE sought to wrap some data around those anecdotal comments.
The survey, which was run across seven countries, talked with over 800 senior IT professionals in companies with more than 250 employees. It sought their views around issues relating to adoption rates, drivers, future plans, and the impact on corporate data, as well as on an IT professional’s career.
The findings show that, while the private cloud is almost ubiquitous in large companies now and is the most popular cloud type for mission-critical applications, attempts to implement OpenStack private cloud have not been without their difficulties. Despite these difficulties, companies remain determined to succeed.
To the findings:
- 90% have implemented private cloud solutions.
- 65% of companies report they have found the implementation experience with private clouds difficult.
- 92% of respondents have concerns about vendor lock-in when it comes to choosing a private cloud infrastructure solution.
- 86% of respondents said the lack of skills in the market is making their companies reluctant to pursue private cloud.
- 81% of IT professionals stated that they are making the move to OpenStack private clouds.
- 15% have already moved to OpenStack private cloud, and 66% plan to at some stage.
- 45% plan to use a commercial distribution for the OpenStack implementation, while 44% plan to download and install OpenStack software elements themselves.
This report is about what I expected, and the bottom line is that OpenStack is the preeminent private cloud choice out there.
But the survey once again raises cause for concern for the broader OpenStack ecosystem. While the fact that OpenStack is hard to adopt might be great for service providers like Mirantis, it does impact upon the level of uptake the project sees. As I've said repeatedly, the foundation should focus less on broadening the scope of the OpenStack project, and more on ensuring that what is there today is strong, stable, reliable, and easy to use.

OpenStack: Still waiting for the users (May 19, 2014)
Years into the open source cloud platform's development, there are plenty of vendors but a lack of end users
OpenStack has an impressive list of corporate backers. Red Hat, Rackspace, HP, IBM and AT&T are contributing thousands of lines of code to the open source project and helping deliver an updated version of the cloud computing platform twice a year to allow for easier installation and better manageability.
Vendors such as HP, Ubuntu, VMware, Yahoo, NetApp, Juniper Networks, Cisco and Dell are all contributing to OpenStack. Even Comcast, Avaya, F5, EMC, Fujitsu, Oracle and Alcatel Lucent have given money and code to the project. OpenStack has no shortage of vendors who believe this software could play an important role in the future of open source cloud computing, and they want in on it.
OpenStack has grown from a mish-mash of code, born out of code half contributed by Rackspace and the other half from NASA in 2010, and has now turned into a force in the cloud world. Thousands of developers contribute to its code each year and vendors line up to get their sponsorships in with it.
But if the project needs one thing, it’s end users.
Despite all that support from service providers across the technology industry, adoption of OpenStack is still so small that IDC analyst Gary Chen says the firm does not even have market share data for it. Some say this is the natural evolution of an initiative that only really got going in earnest two years ago with the creation of an independent foundation to govern the project. Others question with all the marketing and corporate backers, shouldn’t there be more end users at this point?
OpenStack in the wild
While there could perhaps be more, its not like there aren’t any OpenStack users. In the past six to eight months many big name companies like PayPal, Wells Fargo, The Gap, Ericsson and departments at universities like MIT and the University of California have all deployed OpenStack clouds to some degree. Rackspace runs a major part of its international public cloud footprint on OpenStack. But it still seems there is disconnect between the vendor hype of OpenStack and the amount and nature of end user enterprise deployments of it.
Adrian Ionel, president and CEO of pure-play OpenStack distributor Mirantis, doesn’t disagree that there is a gap between the vendors and end users but he says, “it’s closing quickly.” Mirantis is happy to list a litany of customers who are using the framework. For some customers, like PayPal, OpenStack is a key central platform to the company’s IT strategy. Other companies, like John Deere, are testing it out to determine if a larger engagement makes sense.
One of the latest big-name users to join the fold was Ericsson. Mirantis recently closed a five-year $30 million deal to evolve the mobile operator’s backend infrastructure to be managed by OpenStack - which was hailed by the Wall Street Journal as a “milestone” deal for OpenStack.
Ben Kepes, an industry analyst/pundit and blogger, recently asked, “Where are the massive Openstack deals?” In describing the Ericsson deal, he wrote: “The fact that $30M could even be claimed to be one of the larger sized OpenStack deals is a pretty sad indictment of where the initiative is at – with all the collective vendor resource being thrown at OpenStack, and with all the hype it’s generating, it’s a fairly paltry deal for something with so much promise.”
But until the past few months, it seemed that most of the OpenStack announcements were coming from service providers and vendors establishing their cloud platforms based on OpenStack, leading some to question whether the project is for end users or vendors? OpenStack backers say both.
There has been a whole wave of companies started around selling OpenStack, including Piston Cloud Computing Co., Cloudscaling and Mirantis. The Linux distribution companies, Red Hat, SUSE and Ubuntu are each attempting to package OpenStack distros as well. And companies like HP, Dell, Cisco and Rackspace are all using OpenStack in a significant way in their cloud plans. HP, for example, recently rebranded its cloud portfolio to be named Helion and announced a $1 billion commitment to developing its cloud based on OpenStack. HP will have its own distribution of OpenStack, and it’s committed to developing its public and private cloud platforms based on the open source technology.
But Forrester cloud analyst David Bartoletti says while news from HP and Ericsson are great for OpenStack, what the project really needs are enterprise end users. “Where OpenStack is right now, it’s still more about getting vendors to round out their cloud strategies than customers using it for the cloud,” he says. But, given the amount of big-name vendors involved in OpenStack, “it’s not going away.” OpenStack will be around for the long haul.

Microsoft: The second era of cloud platforms
Thursday, February 4, 2016
James Staten Chief Strategist, Cloud + Enterprise, Microsoft
How many people in your company built an app in the cloud in 2015? Get ready for that number to jump dramatically. We’re in the second era of cloud computing and every cloud user is now welcome.
Last week my colleague and Microsoft Azure CTO, Mark Russinovich, talked about his top-of-mind key trends in cloud we are seeing reflected in the market. One of those trends, the rise of application platforms that don't require DevOps skills, will have an outsized impact on the market and most importantly on your company’s agility and ability to innovate.
If we think back to the beginning of the cloud trend, it didn’t start with developers, nor did it start with Infrastructure as a Service. Nope. Back in the late 1990s it started with business professionals leveraging Software as a Service (SaaS). Frankly nearly the whole first decade of cloud was a Shadow IT effort led by the lines of business and the average non-IT employee who brought DropBox, Salesforce, Box.net and many other SaaS applications into our companies. They did this because these tools gave them faster time to solution, aligned to their skill sets and delivered automated business processes and agile advancements.
Today, nearly every company has at least one SaaS application in use, many with 30 or more. Want to find out how many you have? Use the Cloud App Discovery tool in our Enterprise Mobility Suite – the number will surely surprise you.
Shortly after SaaS applications started to take hold, there arose the desire to integrate these SaaS applications into our existing business processes and build new workflows that tied SaaS and non-SaaS together. But this wasn’t nearly as simple as just using SaaS. It required coding, configuration and security skills. And if you wanted to build a truly native cloud application, you needed what emerged next, Infrastructure as a Service. This too was highly automated, scalable and aligned to the skills of the user – a highly technical developer with a mix of coding and IT operations skills or DevOps. As much as IaaS has been empowering to our organizations there’s still a depth of skill required that has thus far limited who can use it.
This is where application platforms like the Azure App Service and open source efforts like Cloud Foundry come in. Layering atop the foundations of IaaS, these tools add a layer of abstraction and further automation of best practices so a different user can be productive in the cloud – the traditional coder. As Forrester notes, DevOps professionals are a small subset of the developer community. Most developers prefer frameworks and platforms that relate services to major application patterns, making those applications easier to deliver*.
Early application platforms were either designed purely to customize and extend a single SaaS solution (like Force.com) or were designed to empower coders using a single programming language or model (such as the early versions of Engine Yard and Google App Platform). But those models proved too limiting and had too much lock-in and thus did not take off. Now we are seeing application platforms that support multiple languages, tie together collections of SaaS and hybrid resources, layer atop container and VM architectures and broaden the types of applications you can build. By 2018, Gartner “expects that at least four out of five leading vendors to offer comprehensive, multipurpose suites of integrated PaaS services.”** With tools like Microsoft PowerApps, now in preview, we’re going to bring application development to even the non-coder. If you have PowerPoint skills, you can build an app with PowerApps.
It doesn’t take a data scientist to realize how much broader the market opportunity can grow when the target customer only needs to know how to code or create a PPT file to build an application. This is the future of cloud computing. And it’s already started. If your coders aren’t tapping into the Azure App Service yet, get them started today.
Also core to the second era of cloud computing is the shift to intelligent applications, incorporate of sensors and the Internet of Things and machine learning insights everywhere. We'll discuss how these trends drive the second wave in coming posts.

Cloud adoption soars, but integration challenges remain
The cloud has quickly become a mainstay in IT departments, with recent research from cloud solutions provider RightScale showing 93 percent of businesses using cloud technology in some form or another. But it’s not all smooth sailing after the initial migration and integration – many businesses find that the second wave of cloud adoption is just as rough as the first.
According to RightScale’s 2015 State of the Cloud report, which surveyed 930 IT professionals about their current adoption and future plans involving cloud computing, 88 percent of businesses are using public cloud technology and 63 percent are using private cloud. Eighty-two percent have a hybrid cloud strategy, up from 74 percent in 2014, a clear indication that the cloud has quickly become an essential ingredient of modern IT.
CompTIA’s Fifth Annual Trends in Cloud Computing Study, conducted in June and July 2014 and released in November 2014, polled 400 IT and business professionals in the United States who are involved in IT decision-making for their organizations; and executives from 400 U.S. IT firms. The data revealed that among companies that have progressed from the first experimental stage to a non-critical use stage, 28 percent rated the transition as requiring significant effort.
But among users that have moved from full production completely through the progression to a transformed IT stage, 63 percent rated the final transition as requiring significant effort.
Cloud integration challenges remain
“The bulk of the cost and effort for any IT project is typically consumed by integration and cloud computing is no different – if anything, cloud integration may be even more challenging, as it requires web APIs that may be unfamiliar to the technical team,” says Seth Robinson, senior director, technology analysis, CompTIA in a statement about the research.
Further complicating matters, many businesses have moved beyond using the cloud for non-critical functions like marketing or CRM and instead rely on cloud technology for storing valuable data. The January 2015 research from cloud provider RightScale revealed 20 percent of respondents are running their enterprise workloads from the cloud and more than half – 55 percent – say their enterprise applications are built on cloud-friendly technology, giving businesses a lot of wiggle room to eventually move those to the cloud.
The CompTIA study found that, as of mid-2014, 59 percent of respondents used the cloud for storage; 48 percent used the cloud for business continuity and disaster recovery and 44 percent for security. That means increased pressure on CIOs to make sure their cloud architecture is secure, accessible and is efficient, and that it seamlessly integrates with other technology.
Sometimes that requires organizations to shift between public cloud providers, or to a hybrid model (with some data in a public cloud and some residing in on-premise systems) or even completely away from the cloud altogether, and each migration brings an additional wave of integration challenges. The CompTIA survey revealed that 44 percent of companies say they’ve moved either infrastructure or applications from one public cloud to another; 25 percent moved from a public cloud into a private cloud; and 24 percent moved from a public cloud back to an on-premise system.
The reasons for these secondary migrations vary. Users may be in search of better offerings and features, greater security, lower cost or a desire for open standards. “If companies are looking for greater compliance and corporate governance, they may shift to a hybrid model to get the best of the both worlds. They’ll use the cloud for non-sensitive, non-critical information they can store cheaply. But they’ll keep sensitive data in a private cloud or on-premise so they have greater control. It’s a strategic decision they’re making,” says Arindam Ray Chaudhuri, COO, Agreeya Solutions.
IT takes a backseat
This shift means that, instead of driving technology decisions that affect the business, IT departments are starting to take a backseat to business decisions mapping out the direction of IT, says Brett Gillett, public cloud lead at IT consulting and solutions provider Softchoice. “The strategic side of the business, all the way up to the C-suite has become more empowered. IT has been in the drivers’ seat for so long, saying, ‘This is the technology we need to get business done,’ but now the C-suite is saying, ‘No, this is the direction we’re going.’ New business imperatives are dictating how companies use IT,” Gillett says.
The RightScale survey revealed that while 62 percent of respondents’ IT departments were still driving decisions about cloud technology, 43 percent say they offer a self-service portal for general business users and 41 percent were planning such a portal.
These lines of business are incredibly empowered by the shift to the cloud, says Chaudhari. With a few mouse clicks, almost any department can access, purchase and use cloud-based technology, often without understanding how those applications or services will (or will not) integrate with an organization’s existing IT stack. “This is something IT departments are really struggling with – that separate lines of business and departments can just grab technology out of the cloud; they don’t have to wait for IT to come do something for them, they do it themselves,” says Chaudari.
Cloud architects are essential
This creates even greater integration hassles; most non-IT end-users aren’t skilled at integration, scaling, provisioning and administrating technology, and IT must get involved after the fact, he says.
Organizations that successfully navigate the initial migration and the secondary integration challenges often find a dedicated cloud architect invaluable, says Gillett. Cloud architects have the necessary installation, scaling, provisioning, networking and administration skills, and are skilled in security best practices, as well. “This is a crucial position for most organizations – there are lots of DevOps skills here, too. You need someone who can be a business analyst to help shape the direction IT is going as well as someone who can get in there, hands-on, and make all these systems work together,” Gillett says.
Though integration challenges remain long after organizations first make the jump to the cloud, it’s clear that the technology is here to stay. Businesses who ride out the current storm and find the right balance of public, private and hybrid cloud solutions will gain a unique advantage over the competitors. “The primary takeaway from all this movement is that no one model is the best answer for every workload,” CompTIA’s Robinson says in the statement. “Companies will be utilizing every type of system as they find the multi-cloud approach that works for them.”

Open Networking User Group looks to reign in ‘Wild West’ of hybrid cloud
Fortune 500 companies complain about lack of standards between public and private clouds
Brandon Butler | Network World
Feb 4, 2016
The Open Networking User Group (ONUG) announced this week the creation of a new working group that will urge cloud service providers to make interoperability between public and private cloud easier.
“It’s a Wild West of how to engage cloud providers,” says Nick Lippis, co-founder of ONUG and an independent analyst. ONUG’s Open Hybrid Cloud committee includes members from organizations such as Cigna, Citigroup, Credit Suisse, FedEx, General Electric, Intuit, JPMorgan Chase, Morgan Stanley, UBS and Unilever.
The working group will be focused on five areas they’d like to see improvements in hybrid cloud computing including: security; contract language and terms; skill sets; lock-in mitigation strategies; and technical architecture.
Lippis says hybrid cloud users have been struck by the lack of standards in the hybrid cloud industry. “Right now there aren’t hybrid cloud users: There are public and private cloud users, but they’re managed totally separately. There are no shared control points.” He’s hoping the Open Hybrid Cloud working group can aggregate concerns among users and communicate those to vendors.
One area the working group will be focusing on is technical architecture. To illustrate the problem, Lippis says many data center operations are based on VMware virtualized compute. Many public clouds are based on OpenStack (like Rackspace) architecture, or use other hypervisors like Xen (AWS) or KVM (Red Hat).
Even analysts agree that hybrid cloud computing has its challenges. Forrester analyst Dave Bartloletti recently examined more than a dozen hybrid cloud management products and found a fragmented market.
On the one hand there are management tools from traditional vendors like VMware and Microsoft. These companies offer hybrid cloud management capabilities, but they work best when staying within the VMware or Microsoft environments. Microsoft, for example recently announced Azure Stack, which is a private cloud that has high fidelity with the Azure public cloud. VMware has demonstrated the ability to do vMotion between VMware virtualized environments and the company’s vCloudAir public cloud. Hybrid cloud works if customers stay within a certain vendor’s products.
Bartoletti found another set of hybrid cloud management tools from startups and third-party providers, such as RightScale, Cliqr and others. These platforms attempt to act as a gateway between on-premises workloads and the public cloud. Bartoletti says hybrid cloud management tools are ready for production, but many are still maturing.
One problem with hybrid cloud is that the major public cloud vendors – namely Amazon Web Services and Google Compute Platform – don’t have much of an incentive to manage on-premises private clouds. Their view is that most all workloads should live in the public cloud, or in virtual private clouds they host. Perhaps getting some big name, Fortune 500 customers complaining about the issues will change their viewpoint.
The Open Hybrid Cloud committee is one of nine working groups ONUG has. Others include: virtual networks/overlays; SD-WAN; traffic monitoring/visibility/network state collection, correlation and analysts; common tools for automating initial configuration and change management; SDN Federation/operability; Software defined data center security fabric; network services broker; and now Open Hybrid cloud. The Open Hybrid Cloud working group will present their findings at ONUG’s spring meeting taking place in May.

Rackspace Needs More Than OpenStack Neutron
February 5, 2016
Rackspace has bragging rights for co-creating OpenStack, along with NASA, back in 2010. Since then, the company has carved a name for itself offering private clouds to enterprises. Now Rackspace says it will resell PLUMgrid’s software-defined networking (SDN) for its Rackspace Private Cloud.
Rackspace deploys and manages its OpenStack-based clouds with the Ansible tool, and it has been using OpenStack SDN capabilities via Neutron for networking in private clouds.
“[Neutron] works for many use cases,” says Brian Thompson, senior director of product management with Rackspace. But he says its larger enterprise customers have needs that Neutron can’t fill: for security, tenant isolation, scale, and performance, as well as a level of specific monitoring at the network level.
“PLUMgrid’s SDN provides that capability within an OpenStack environment,” he says. “We configure an OpenStack private cloud and then deploy PLUMgrid for the SDN components.”
The arrangement with PLUMgrid makes advanced SDN available for large enterprises that need more scale.
“We’ve implemented our own way to make up for the shortcomings of [Neutron’s] generic codes,” says PLUMgrid CEO Larry Lang. “When you first start experimenting, you may not care about scalability or availability.”
But with Rackspace’s success, scalability becomes an issue. PLUMgrid’s SDN is designed to support larger enterprise customers with hundreds of physical nodes.
PLUMgrid provides a programmable data plane, and it offers security by enabling virtual domains via micro-segmentation and firewall insertion. Its CloudApex provides real-time SDN visualization and monitoring.
PLUMgrid also supports Mirantis OpenStack, Red Hat OpenStack, and Ubuntu OpenStack by Canonical.
ICYMI:[EN] OpenStack Neutron is suitable for deployments of 30 nodes or fewer
