jumps on a conversation
 C: Start with a clean source code template, fluent with the tool chain
Maturity:
 Are you asking questions?
 Rephrasing the problem?
 Or just jumping without thinking?
What we’re looking for:

S3 Server was founded by Scality, after a team created open source object-storage at a Hackathon in Paris, France. To keep our innovation, (and innovative team) growing, what better way than to host a hackathon of our own? The goal of the hackathon was to showcase the endless creativity in advancing storage applications, or integrations for current storage solutions. This 3-day event was sponsored by Seagate and Holberton School. These slides are a recap from Day 1.

Policy driven SDN in CloudStack

ShapeBlue

The Nuage Networks Virtualized Cloud Services solution integrates seamlessly with CloudStack’s advanced networking, supporting Shared Networks, Isolated Networks and VPC’s for KVM and ESXI hypervisors. That integration is bidirectional in the way that networks can be provisioned in CloudStack and be programmed into Nuage, as can be provisioned as advanced networking topologies within Nuage and be consumed from CloudStack. Empowered with SDN, operators can boost their clouds with networking scalability and performance which through native VR networking cannot be met.

Monitor Kubernetes in Rancher using InfluxData

InfluxData

Containers make software development easier, enabling you to write code faster and run it better. However, running containers in production can be hard. Rancher includes everything you need to manage containers in production—you no longer need to build container management platforms from scratch using multiple open source technologies. Infrastructure services management and the overlay networking, storage, and load balancing capabilities provide the basis for portability across infrastructure providers. In this webinar, William Jiminez, Solutions Architect at Rancher Labs, and Gunnar Aasen, Partner Engineering, provide an introduction to Rancher and InfluxData. From there, they will show you how to use the two together to setup and monitor your containers and microservices to properly manage your infrastructure and track key metrics (CPU, RAM, storage, network utilization), as well as the availability of your application endpoints.

InfluxData

How to Gain Visibility into Containers, VM’s and Multi-Cloud Environments Using Telegraf, InfluxDB and Mist Mist.io are the creators of Mist, the open source multi-cloud management platform. Their solution helps clients manage the complexities of using a mix of public and private clouds, hypervisors, containers and bare metals. Mist streamlines its customers’ operations and optimizes costs by improving DevOps practices. Discover how Mist achieves that by building on top of Telegraf and InfluxDB. Join this webinar as Chris Psaltis and Dimitris Moraitis dive into: Mist’s approach to improving visibility across environments How a time series database is used to monitor infrastructures Mist’s ability to automate processes and reduce infrastructure costs

The more your team can collaborate around data, the more useful that data is. This is especially true for time-series data that is increasingly the heartbeat of your business. When your entire team can utilize time series data, they know the pulse of your devices, your equipment, your customers, and your software -- and can act accordingly. In this webinar, product manager Russ Savage will show you three new ways for your team to collaborate around time-series data. First, InfluxDB Notebooks let you create and share computational narratives that combine live code, visualizations, and explanatory notes, which can output to your InfluxDB Dashboards, Tasks, and Buckets. You can use Notebooks to better document your downsampling, data processing, incident investigations, postmortems, and runbooks. Next, InfluxDB Annotations let you explain the why behind time series data trends. Annotations can be used to communicate how time series data is impacted by changes to software deployments (like configurations, upgrades, or outages), user behavior (Cyber Monday, deadlines), business activities (ad campaign, sales incentives), or external events (natural disasters, weather). With team members sharing contextual clues, you’ll more quickly determine root cause and restore services faster. Finally, learn how to apply gitops practices to managing InfluxDB configurations, dashboards, tasks, and alerts, as well as Telegraf configurations, ensuring better collaboration workflows between developers, SREs, and every stakeholder involved in time series collection, enrichment, and analysis.

Driving Network and Marketing Investments at O2 by Focusing on Improving the ...

DataWorks Summit

The idea was to predict the customer experience, and their perception of the O2 network at both the user and area levels to drive the network and marketing investments. Here is why and how we got there. In order to measure and predict customer network experience, O2 needed a streaming big data solution which would consume billions of events coming in from the network, in real-time, to measure the performance of the network as experienced by the customer. It was important to build a platform to gather all the relevant data; to co-relate that with the customer satisfaction index (CSI) surveys to understand the relationship of metrics to score. We applied machine learning methods to predict the CSI for all users on the network. Customer insights from the network helped us to build customer segmentations which are shaping various marketing and digital propositions at O2. - The overall solution was based on a hybrid architecture, where Open Source technologies were brought together with Tableau visualization which enabled O2 to keep the maintenance cost down to a minimum. - In order to have quick ROI, the solution was built as the prototype which continued to evolve and now currently handles 30 billion transactions a day, continuously streaming into the platform, and predicting customer experience for 35m+ users. The O2 solution continued to expand every year to accommodate multi-fold growth in traffic, and to accommodate additional features. The decision to move from a community edition Hadoop to the Hortonworks-based platform enabled us to have a supported, faster, and more reliable service. The migration to Hortonworks was completed in October 2018 which has given us the reliable platform to expand the analytics use cases across the wider O2 businesses.

Global Data Management – a practical framework to rethinking enterprise, oper...

DataWorks Summit

Global data management is not a newly coined term. However, what it stands for is actually widening in scope particularly around data-in-motion and data-at-rest. Significant technology trends such as IoT, cloud, AI/ML, blockchain, and streaming data have given rise to excessive data volumes and also innovative use cases. The scope for global data management now extends all the way from ingestion, processing, storage, governance, security to analysis. With a good number of endpoints served through the cloud and major application footprints remaining on-premisess, it is pertinent to have a global data management strategy that supports hybrid models and more specifically, a multi-cloud model. Many modern businesses struggle to balance the demands of rapidly innovating through new technologies like machine learning with the need to keep data safe and secure, all while responding to a constantly changing regulatory landscape. This puts data stewards, data engineers, architects, data scientists, and analysts under intense pressure as they must contend with existing and new applications, multiple logical and physical data stores and sources, diverse data types, and data spread across several deployment environments. Attend this session led by Matt Aslett, Research Director at 451 Research and Dinesh Chandrasekhar, Director, Hortonworks to learn more about creating a framework for your enterprise that offers guidance on how to think about global data management—priorities, responsibilities, key stakeholders, compliance, and growth.

Effective Application Security in Software Delivery lifecycle using Deployment Firewall and DBOM The modern software delivery process (or the CI/CD process) includes many tools, distributed teams, open-source code, and cloud platforms. Constant focus on speed to release software to market, along with the traditional slow and manual security checks has caused gaps in continuous security as an important piece in the software supply chain. Today organizations feel more susceptible to external and internal cyber threats due to the vast attack surface in their applications supply chain and the lack of end-to-end governance and risk management. The software team must secure its software delivery process to avoid vulnerability and security breaches. This needs to be achieved with existing tool chains and without extensive rework of the delivery processes. This talk will present strategies and techniques for providing visibility into the true risk of the existing vulnerabilities, preventing the introduction of security issues in the software, resolving vulnerabilities in production environments quickly, and capturing the deployment bill of materials (DBOM). Speakers: Bob Boule Robert Boule is a technology enthusiast with PASSION for technology and making things work along with a knack for helping others understand how things work. He comes with around 20 years of solution engineering experience in application security, software continuous delivery, and SaaS platforms. He is known for his dynamic presentations in CI/CD and application security integrated in software delivery lifecycle. Gopinath Rebala Gopinath Rebala is the CTO of OpsMx, where he has overall responsibility for the machine learning and data processing architectures for Secure Software Delivery. Gopi also has a strong connection with our customers, leading design and architecture for strategic implementations. Gopi is a frequent speaker and well-known leader in continuous delivery and integrating security into software delivery.

Fwdays

I have heard many times that architecture is not important for the front-end. Also, many times I have seen how developers implement features on the front-end just following the standard rules for a framework and think that this is enough to successfully launch the project, and then the project fails. How to prevent this and what approach to choose? I have launched dozens of complex projects and during the talk we will analyze which approaches have worked for me and which have not.
