OpenStack

• The OpenStack system consists of several key services that are separately installed. These services work together depending on your cloud needs and include the Compute, Identity, Networking, Image, Block Storage, Object Storage, Telemetry, Orchestration, and Database services. You can install any of these projects separately and configure them stand-alone or as connected entities. Get started with OpenStack

• The OpenStack project is an open source cloud computing platform for all types of clouds, which aims to be simple to implement, massively scalable, and feature rich. Developers and cloud computing technologists from around the world create the OpenStack project. • OpenStack provides an Infrastructure-as-a-Service (IaaS) solution through a set of interrelated services. Each service offers an application programming interface (API) that facilitates this integration. Depending on your needs, you can install some or all services. Current trends and deployments Some famous Companies; OpenStack users

•OpenStack is used by companies like Comcast, PayPal, Walmart, , CERN, LexisNexis, AT&T, China Mobile, among many others, and by Her Majesty’s Revenue and Customs in the UK. The market is strong for companies like telcos.

The

•The Volkswagen group comprises , Bentley, Bugatti, Ducati, Lamborghini, Man, Neoplan , Seat, Scania, Skoda, Volkswagen cars and Volkswagen commercial vehicles. It employs 600,000 people and has production facilities in 40 countries.

Comcast and OpenStack

• At Comcast, we use OpenStack for a wide range of purposes, from developing new apps, services and products, such as the recently launched Xfinity Share app, to operating millions of our customers’ cloud-enabled X1 set-top boxes. • Using the Comcast Elastic Cloud, powered by OpenStack, our development teams across the country can create, deploy and scale new apps for X1 in a matter of weeks, rather than months. https://www.youtube.com/watch?v=Cux-7GJqcqc&t=1016s atmail atmail Virtualizing your Live-TV HeadEnd Multicast and zero packet loss on OpenStack https://www.youtube.com/watch?v=1r2FbFI3KFo

The OpenStack Public Cloud • https://www.openstack.org/passport/ Passport OpenStack powered Public Clouds

https://www.openstack.org/marketplace/public-clouds/ Cloud Repatriation •An 2016 article in Forbes cites a study conducted by 451 Research that found that 20% of cloud users had moved one or more of their workloads from the public cloud back on premises. There is even a name for this migration: cloud repatriation. Cloud Repatriation & private cloud

•The same study also found that an additional 10% of public cloud users were planning to move some workloads back to a private cloud in the future. In total, those who embarked on cloud repatriation planned to do so with 40% of their current public cloud workloads. OpenStack with hybrid Cloud

• Today, hybrid cloud is a reality and multi-cloud has become a real possibility. With hybrid clouds, customers can have a mixed pool of resources between multiple public and private clouds. With OpenStack running in the private cloud side of this hybrid implementation, enterprises can avoid vendor lock-in with their cloud infrastructure while also being able to deploy multiple private clouds using a single API at the infrastructure layer. OpenStack for NFV

•According to an August 2016 survey conducted by Heavy Reading and the OpenStack Foundation, more than 60% of telecoms are already using, or currently testing, new use cases with OpenStack for NFV, and 86% of telecoms respondents considered OpenStack to be essential or important to their success. OpenStack for NFV

• One example is Verizon, one of the biggest telecom companies in the United States, which worked with Big Switch Networks, Dell, and Red Hat to develop an OpenStack pod-based design. This created the industry’s largest-known network function virtualization (NFV) OpenStack cloud deployment across U.S. data centers, adding resiliency at scale with no bandwidth bottlenecks and reduced operational complexity. • Other telecoms running OpenStack are Sprint, Comcast, Ericsson, and China Telecom. OpenStack’s Future

• The future of OpenStack is bright in the private cloud, hybrid cloud, and with NFV. Private cloud (or hybrid) is here to stay, and more and more companies are looking for a balanced approach to their cloud migrations that includes integrating private and public clouds. • And as more telecom companies adopt OpenStack for their NFV and the agility and scalability it enables, they are contributing back to the project. • There's no doubt: The future looks strong for OpenStack.
