May 19, 2016:
With OpenStack in tow you’ll go far — be it your house, your bank, your city or your car.
Just look at all of the exciting places we’re going:
From the phone in your pocket
The telecom industry is undergoing a massive shift, away from hundreds of proprietary devices in thousands of central offices accumulated over decades, to a much more efficient and flexible software plus commodity hardware approach. While some carriers like AT&T have already begun routing traffic from the 4G networks over OpenStack powered clouds to millions of cellphone users, the major wave of adoption is coming with the move to 5G, including plans from AT&T, Telefonica, SK Telekom, and Verizon.
We are on the cusp of a revolution that will completely re-imagine what it means to provide services in the trillion dollar telecom industry, with billions of connected devices riding on OpenStack-powered infrastructure in just a few years.
To the living room socket
The titans of TV like Comcast, DirecTV, and Time Warner Cable all rely on OpenStack to bring the latest entertainment to our homes efficiently, and innovators like DigitalFilm Tree are producing that content faster than ever thanks to cloud-based production workflows.
Your car, too, will get smart
Speaking of going places, back here on earth many of the world’s top automakers, such as BMW and the Volkswagen group, which includes Audi, Lamborghini, and even Bentley, are designing the future of transportation using OpenStack and big data. The hottest trends to watch in the auto world are electric zero emissions cars and self-driving cars. Like the “smart city” mentioned above, a proliferation of sensors plus connectivity call for distributed systems to bring it all together, creating a huge opportunity for OpenStack.
And your bank will take part
Money moves faster than ever, with digital payments from startups and established players alike competing for consumer attention. Against this backdrop of enormous market change, banks must meet an increasingly rigid set of regulatory rules, not to mention growing security threats. To empower their developers to innovate while staying diligent on regs and security, financial leaders like PayPal, FICO, TD Bank, American Express, and Visa are adopting OpenStack.
Your city must keep the pace
Powering the world’s cities is a complex task and here OpenStack is again driving automation, this time in the energy sector. State Grid Corporation, the world’s largest electric utility, serves over 120 million customers in China while relying on OpenStack in production.
Looking to the future, cities will be transformed by the proliferation of fast networks combined with cheap sensors. Unlocking the power of this mix are distributed systems, including OpenStack, to process, store, and move data. Case in point: tcpcloud in Prague is helping introduce “smart city” technology by utilizing inexpensive Raspberry Pis embedded in street poles, backed by a distributed system based on Kubernetes and OpenStack. These systems give city planners insight into traffic flows of both pedestrians and cars, and even measure weather quality. By routing not just packets but people, cities are literally load balancing their way to lower congestion and pollution.
From inner to outer space
The greatest medical breakthroughs of the next decade will come from analyzing massive data sets, thanks to the proliferation of distributed systems that put supercomputer power into the hands of every scientist. And OpenStack has a huge role to play empowering researchers all over the globe: from Melbourne to Madrid, Chicago to Chennai, or Berkeley to Beijing, everywhere you look you’ll find OpenStack.
To explore this world, I recently visited the Texas Advanced Computing Center (TACC) at the University of Texas at Austin where I toured a facility that houses one of the top 10 supercomputers in the world, code named “Stampede
But what really got me excited about the future was the sight of two large OpenStack clusters: one called Chameleon, and the newest addition, Jetstream, which put the power of more than 1,000 nodes and more than 15,000 cores into the hands of scientists at 350 universities. In fact, the Chameleon cloud was recently used in a class at the University of Arizona by students looking to discover exoplanets. Perhaps the next Neil deGrasse Tyson is out there using OpenStack to find a planet to explore for NASA’s Jet Propulsion Laboratories.
Where should we go next?

From OpenStack Summit Austin, Part 1: Vendors digging in for long haul by Al Sadowski, 451 Research, LLC: This report provides highlights from the most recent OpenStack Summit
THE 451 TAKE OpenStack mindshare continues to grow for enterprises interested in deploying cloud-native applications in greenfield private cloud environments. However, its appeal is limited for legacy applications and enterprises sold on hyperscale multi-tenant cloud providers like AWS and Azure. There are several marquee enterprises with OpenStack as the central component of cloud transformations, but many are still leery of the perceived complexity of configuring, deploying and maintaining OpenStack-based architectures. Over the last few releases, processes for installation and upgrades, tooling, and API standardization across projects have improved as operators have become more vocal during the requirements phase. Community membership continues to grow on a global basis, and the supporting organization also depicts a similar geographic trend.
… Horizontal scaling of Nova is much improved, based on input from CERN and Rackspace. CERN, an early OpenStack adopter, demonstrated the ability for the open source platform to scale – it now has 165,000 cores running OpenStack. However, Walmart, PayPal and eBay are operating larger OpenStack environments.

May 9, 2016: From OpenStack Summit Austin, Part 1: Vendors digging in for long haul continued:
While OpenStack may have been conceived as an open source multi-tenant IaaS, its future success will mainly come from hosted and on-premises private cloud deployments. Yes, there are many pockets of success with regional or vertical-focused public clouds based on OpenStack, but none with the scale of AWS or the growth of Microsoft Azure. Hewlett Packard Enterprise shuttered its OpenStack Helion-based public cloud, and Rackspace shifted engineering resources away from its own public cloud. Rackspace, the service provider with the largest share of OpenStack-related revenue, says its private cloud is growing in the ‘high double digits.’ Currently, 56% of OpenStack’s service-provider revenue total is public cloud-based, but we expect private cloud will account for a larger portion over the next few years.

- OVH is based in France and operates a predominately pan-Europe public cloud. It added Nova compute in 2014, and currently has 75PB on Swift storage.
- Unitas Global says OpenStack-related enterprise engagements are a large part of its 100% Y/Y growth. While it does not contribute code, it is helping to develop operational efficiencies and working with Canonical to deploy ‘vanilla’ OpenStack using Juju charms. Tableau Software is a client.
- DreamHost is operating an OpenStack public cloud, DreamCompute, and is a supporter of the Astara (network orchestration) project. It claims 2,000 customers for DreamCompute and 10,000 customers for its object storage product.
- Platform9 is a unique OpenStack in SaaS startup with 20 paying customers. Clients bring their own hardware, and the software provides the management functions and takes care of patching and upgrades.
- AppFormix is a software startup focused on cloud operators and application developers that has formed a licensing agreement with Rackspace. Its analytics and capacity-planning dashboard software will now be deployed on Rackspace’s OpenStack private cloud. The software also works with Azure and AWS.
- Tesora is leveraging the Trove project to offer DBaaS. The vendor built a plug-in for Mirantis’ Fuel installer. The collaboration claims to make commercial, open source relational and NoSQL databases easier for administrators to deploy.

How has OpenStack transformed your business?
AT&T is a legacy telco which is transforming itself by adopting virtual infrastructure and a software defined networking focus in order to compete in the market and create value for customers in the next five years and beyond.
- Virtualization and virtual network functions (VNFs) are of critical importance to the Telecom industry to address growth and agility. AT&T’s Domain 2.0 Industry Whitepaper released in 2013 outlines the need as well as direction.
- AT&T chose OpenStack as the core foundation of their cloud and virtualization strategy
- OpenStack has reinforced AT&T’s open source strategy and strengthened our dedication to the community as we actively promote and invest resources in OpenStack
- AT&T is committing staff and resources to drive the vision and innovation in the OpenStack and OPNFV communities to help drive OpenStack as the default cloud orchestrator for the Telecom industry
- AT&T as a founding member of the ETSI ISG network functions virtualization (NFV) helped drive OpenStack as the cloud orchestrator in the NFV platform framework. OpenStack was positioned as the VIM – Virtual Infrastructure Manager. This accelerated the convergence of the Telco industry onto OpenStack.
OpenStack serves as a critical foundation for AT&T’s software-defined networking (SDN) and NFV future and we take pride in the following:
- AT&T has deployed 70+ OpenStack (Juno & Kilo based) clouds globally, which are currently operational. Of the 70+ clouds 57 are production application and network clouds.
- AT&T plans 90% growth, going to 100+ production application and network clouds by the end of 2016.
- AT&T connects more than 14 million wireless customers via virtualized networks, with significant subscriber cut-over planned again in 2016
- AT&T controls 5.7% of our network resources (29 Telco production grade VNFs) with OpenStack, with plans to reach 30% by the end of 2016 and 75% by 2020.
- AT&T trained more than 100 staff in OpenStack in 2015
AT&T plans to expand to expand its community team of 50+ employees in 2016 As the chosen cloud platform OpenStack enabled AT&T in the following SDN and NFV related initiatives:
- Our recently announced 5G field trials in Austin

- Internet-scale storage service
- Putting all AT&T’s workloads on one common platform Deployment Automation: OpenStack modules have enabled AT&T to cost-effectively manage the OpenStack configuration in an automated, holistic fashion.
- Using OpenStack Heat, AT&T pushed rolling updates and incremental changes across 70+ OpenStack clouds. Doing it manually would be take many more people and a much longer schedule.
- Using OpenStack Fuel as a pivotal component in its cloud deployments AT&T accelerates the otherwise consuming, complex, and error-prone process of deploying, testing, and maintaining various configuration flavors of OpenStack at scale. AT&T was a major contributor towards Fuel 7.0 and Fuel 8.0 requirements. OpenStack has been a pivotal driver of AT&T’s overall culture shift. AT&T as an organization is in the midst of a massive culture shift from a Legacy Telco to a company where new skills, techniques and solutions are embraced.
OpenStack has been a key driver of this transformation in the following ways:
- AT&T is now building 50 percent of all software on open source technologies
- Allowing for the adoption of a dev ops model that creates a more unified team working towards a better end product

April 30, 2016: Swisscom in Production with OpenStack and Cloud Foundry
Swisscom has one of the largest in-production industry standard Platform as a Service built on OpenStack. Their offering is focused on providing an enterprise-grade PaaS environment to customers worldwide and with various delivery models based on Cloud Foundry and OpenStack. Swisscom embarked early on the OpenStack journey to deploy their app cloud partnering with Red Hat, Cloud Foundry, and PLUMgrid. With services such as MongoDB, MariaDB, RabbitMQ, ELK, and an object storage, the PaaS cloud offers what developers need to get started right away. Join this panel for take-away lessons on Swisscom’s journey, the technologies, partnerships, and developers who are building apps everyday on Swisscom’s OpenStack cloud.
May 23, 2016: How OpenStack public cloud + Cloud Foundry = a winning platform for telecoms interview on ‘OpenStack Superuser’ with Marcel Härry, chief architect, PaaS at Swisscom
Swisscom has one of the largest in-production industry standard platform-as-a-service built on OpenStack.
Their offering focuses on providing an enterprise-grade PaaS environment to customers worldwide and with various delivery models based on Cloud Foundry and OpenStack. Swisscom, Switzerland’s leading telecom provider, embarked early on the OpenStack journey to deploy their app cloud partnering with Red Hat, Cloud Foundry and PLUMgrid.
Superuser interviewed Marcel Härry, chief architect, PaaS at Swisscom and member of theTechnical Advisory Board of the Cloud Foundry Foundation to find out more.
How are you using OpenStack?
OpenStack has allowed us to rapidly develop and deploy our Cloud Foundry-based PaaS offering, as well as to rapidly develop new features within SDN and containers. OpenStack is the true enabler for rapid development and delivery.
An example: after half a year from the initial design and setup, we already delivered two production instances of our PaaS offering built on multiple OpenStack installations on different sites. Today we are already running multiple production deployments for high-profile customers, who further develop their SaaS offerings using our platform. Additionally, we are providing the infrastructure for numerous lab and development instances. These environments allow us to harden and stabilize new features while maintaining a rapid pace of innovation, while still ensuring a solid environment.
We are running numerous OpenStack stacks, all limited – by design – to a single region, and single availability zone. Their size ranges from a handful of compute nodes, to multiple dozens of compute nodes, scaled based on the needs of the specific workloads. Our intention is not to build overly large deployments, but rather to build multiple smaller stacks, hosting workloads that can be migrated between environments. These stacks are hosting thousands of VMs, which in turn are hosting tens of thousands of containers to run production applications or service instances for our customers.
What kinds of applications or workloads are you currently running on OpenStack?
We’ve been using OpenStack for almost three years now as our infrastructure orchestrator. Swisscom built its Elastic Cloud on top of OpenStack. On top of this we run Swisscom’s Application Cloud, or PaaS, built on Cloud Foundry with PLUMgrid as the SDN layer. Together, the company’s clouds deliver IaaS to IT architects, SaaS to end users and PaaS to app developers among other services and applications. We mainly run our PaaS/Cloud Foundry environment on OpenStack as well as the correlated managed services (i.e. a kind of DBaaS, Message Service aaS etc.) which are running themselves in Docker containers.
What challenges have you faced in your organization regarding OpenStack, and how did you overcome them?
The learning curve for OpenStack is pretty steep. When we started three years ago almost no reference architectures were available, especially none with enterprise-grade requirements such as dual-site, high availability (HA) capabilities on various levels and so forth. In addition, we went directly into the SDN, SDS levels of implementation which was a big, but very successful step at the end of the day.
What were your major milestones?
Swisscom’s go-live for its first beta environment was in spring of 2014, go live for an internal development (at Swisscom) was spring of 2015, and the go-live for its public Cloud Foundry environment fully hosted on OpenStack was in the fall of 2015. The go-live date for enterprise-grade and business-critical workloads on top of our stack from various multinational companies in verticals like finance or industry is spring, 2016, and Swisscom recently announced Swiss Re as one of its first large enterprise cloud customers.
What have been the biggest benefits to your organization as a result of using OpenStack?
Pluggability and multi-vendor interoperability (for instance with SDN like PLUMgrid or SDS like ScaleIO) to avoid vendor lock in and create a seamless system. OpenStack enabled Swisscom to experiment with deployments utilizing a DevOps model and environment to deploy and develop applications faster. It simplified the move from PoC to production environments and enabled us to easily scale out services utilizing a distributed cluster-based architecture.
What advice do you have for companies considering a move to OpenStack?
It’s hard in the beginning but it’s really worth it. Be wise when you select your partners and vendors, this will help you to be online in a very short amount of time. Think about driving your internal organization towards a dev-ops model to be ready for the first deployments, as well as enabling your firm to change deployment models (e.g. going cloud-native) for your workloads when needed.
How do you participate in the community?
This year’s Austin event was our second OpenStack Summit where we provided insights into our deployment and architecture, contributing back to the community in terms of best practices, as well as providing real-world production use-cases. Furthermore, we directly contribute patches and improvements to various OpenStack projects. Some of these patches have already been accepted, while a few are in the pipeline to be further polished for publishing. Additionally, we are working very closely together with our vendors – RedHat, EMC, ClusterHQ/Flocker, PLUMgrid as well as the Cloud Foundry Foundation – and work together to further improve their integration and stability within the OpenStack project. For example, we worked closely together with Flocker for their cinder-based driver to orchestrate persistency among containers. Furthermore, we have provided many bug reports through our vendors and have worked together with them on fixes which then have made their way back into the OpenStack community.
We have a perfect solution for non-persistent container workloads for our customers. We are constantly evolving this product and are working especially hard to meet the enterprise- and finance-verticals requirements when it comes to the infrastructure orchestration of OpenStack.
Härry spoke about OpenStack in production at the recent Austin Summit, along with Pere Monclus of PLUMgrid, Chip Childers of the Cloud Foundry Foundation, Chris Wright of Red Hat and analyst Rosalyn Roseboro.
