History teaches us that astonishing feats occur not when a singular leader envisions them, but when a mass of skilled workers collaborate to transform that vision into something material. The Pyramids of Giza, for example, were not built overnight by a Pharaoh, but constructed by tens of thousands of workers over a period of years. Today’s “pyramid” is quite a bit smaller, but a wonder of the world in its own right: The iPhone has transformed the world as we know it -- but most of its power comes from the app store, which offers thousands of apps created from the imaginations of thousands of developers. These developers are the makers of marvels in our time. They instantiate the very concept of digital transformation -- that notion of infrastructure disruption and re-assembly on the mind of every CIO. Business development is driven by software development, and software development is shaped by developers in the open source community.
In her talk, Abby Kearns empowers developers to think of themselves as the doers and makers who hold the key to unlocking digital transformation. She will cover the importance of diversity among developers for the technology industry to evolve and to reflect its user base, and will highlight the key open source concepts and technologies powering this trans-industrial transformation.
New technologies, namely driven by open source communities, are accelerating digital transformation. Blockchain is one of such technologies. Unique feature about Blockchain, compared to other technologies, is power of trust needed in digital age. Its power enables a person, or small community to be as trustful as big enterprises. Blockchain also empowers a person to control back ownership of their digital assets including personal information. These power of Blockchain comes from its security. Blockchain security will be increasingly important in coming digital age. NEC Research Lab in EU has been leading academic research on Blockchain security since the beginning of bitcoin. With strong background of Blockchain security research lab, NEC will contribute more on open source community.
Hitachi’s main business domain is social Infrastructure, which includes Utility, Transportation, Healthcare and so on. To apply OSS to those domains, there are requirement sfrom those areas. In this lightening talk, I would like to talk about Hitachi’s trial to apply OSS to the social system.
WalB is an open-source backup system that consists of block devices, called WalB devices, and userland utilities, called WalB tools. A WalB device records write-I/Os. WalB tools extracts them to create restorable snapshots in an incremental manner.
Compared with dm-snap and dm-thin, WalB is designed to achieve small I/O latency overhead and short backup time. We conducted an experiment to take an incremental backup of a volume under random write workload. The result confirms those advantages of WalB.
Cybozu cloud platform, which has 500TB volumes and processes 25TB write-I/Os per day, is required to achieve (1) stable workload performance without I/O spikes which may affect application user experience and (2) short backup interval specified in our service level objective. WalB satisfies the requirements, while dm-snap is not enough to and dm-thin is not expected to.
Over the last two decades, the fundamental building blocks of application delivery have evolved. It started with non-virtualized servers from Sun, moved to virtual machines from VMWare and AWS (on first private and then public clouds, the latter being called Infrastructure-as-a-Service), and then continued to buildpacks on Platform-as-a-Service offerings such as Heroku. We’ll review this evolution, and the subsequent one toward open source approaches to VMs, IaaS, and PaaS like OpenStack and Cloud Foundry.
Finally, we'll see how these pieces have evolved to the standard architecture today of orchestrated containers as part of a microservices architecture, and how Kubernetes is establishing itself as the Linux of the cloud. We'll discuss some of the advantages of a cloud native architecture, including isolation, avoiding lock-in, scalability, agility and maintainability, efficiency and resiliency.
ARM servers are about to enter the mainstream after many years of development. This is especially true in Japan, home to SoftBank, and also to the Post K ARM powered supercomputer. Jon Masters has been involved in ARM servers since the beginning. In this talk, he will discuss the history of ARM servers, explaining what defines an ARM server and how they differ from the alternatives, and how to practically build and deploy an ARM server installation. Many common issues are discussed and advice is given for those on the cutting edge who plan to deploy in 2017.
Along with factors such as performance, scalability and usability, security is one of the key characteristics by which those who deploy open source judge your project. Just like those other characteristics, it doesn't just happen on its own and needs to be prioritised.
In this talk Dr. Nicko van Someren will present the Linux Foundation's Core Infrastructure Initiative (CII) and describe some of the efforts it is making to help open source projects improve their own security. He will discuss some of the measure and steps that projects can take to enhance their security processes and discuss the CII's Best Practice Badges Program, a free open source secure development maturity model, designed with and for the open source community. Citing both good and bad examples, he’ll dive into what progress is or isn’t being made with security vis a vis the software development lifecycle.
Open Source Software is at the heart of the internet and as a result much of the core infrastructure on which we all rely is built through collaborative and open development. Many of the open source components on which we rely have evolved over extended periods of time. While open development make public code review easier it also presents unique challenges for the secure development process. In this talk Nicko van Someren, the Linux Foundation CTO, will examine what makes open source security different, where it is easier and where it is harder than close source, and how the Linux Foundation's Core Infrastructure Initiative is working to make it better.
Let's Encrypt has been a success for the open source community and for privacy in today's world. Within months of launch Let's Encrypt was one of the largest issuers of certificates on planet earth. This talk will review some of the functionality, goals and mission of Let's Encrypt and focus in on it's struggle and success as a little startup in a saturated market.
