Adobe Experience Manager helps you organize and manage the delivery of creative assets and other content across all of your digital marketing channels. MongoDB enables applications and system to scale beyond the ordinary assumptions in flexible and and agile way. Operating large scalable digital asset management system requires a certain understanding of how data is handled and how data is consumed. This talk his about how to make the most out of these 2 technologies: how to operate, maintain and optimize these system using the best practices and lessons learn from existing installation of AEM and MongoDB.

Managing your Hadoop Clusters with Ambari

DataWorks Summit

Apache Ambari provides a 100% open source and intuitive set of tools to monitor, manage and efficiently provision your Apache Hadoop cluster. Ambari simplifies the operation and hides the complexity of Hadoop, making Hadoop appear like a single, cohesive data platform. Hadoop cluster provisioning and ongoing management can be a complicated task, especially when there are hundreds or thousands of nodes involved. Ambari allows you to control Hadoop cluster services from a single point. In this session, we will provide an overview of the Apache Ambari key features, architecture and web service-based APIs.

Apache Ambari is now the preferred way of provisioning, managing and monitoring Hadoop Clusters. Ambari helps users to manage Hadoop clusters simplifying actions such as upgrades, configuration management, service management, etc. From release 2.0, Ambari started supporting automated Rolling Upgrades. This was further enhanced with release 2.2.0.0 to include support for Express Upgrades, which allows users to upgrade large scale clusters faster but requiring cluster downtime. This talk will cover planning and execution of Hadoop cluster upgrades from an operational perspective. The talk will also cover the internals of the upgrade process including the various stages such as pre-upgrade, backup, service checks, configuration upgrades, and finalization. Finally, the talk will cover troubleshooting upgrade failures, monitoring services during upgrades and post upgrade actions. The presentation will conclude with a case study that will cover how the upgrade process works on a large cluster (including aspects such as planning the upgrade, the amount of time required for the various stages, and troubleshooting)

Managing your Hadoop Clusters with Apache Ambari

DataWorks Summit

Deploying, configuring, and managing large Apache Hadoop and HBase clusters can be quite complex. Once you have your clusters, keeping them up and running and making sure that the SLAs are met presents even more challenges and headaches to Hadoop operators. To make matters worse, managing upgrades can be a nightmare. Hadoop users are presented with their own fair share of difficulties such as slow running jobs and not knowing why they are slow. For third-party software vendors interested in incorporating Hadoop management and monitoring capabilities, there does not seem to be an obvious, easy solution. Apache Ambari is aimed at making lives of Hadoop operators, users, and integrators simpler by providing a management interface to do all of that and more. This session presents usages of Ambari`s Web UI for Hadoop operators (deploying, managing, and monitoring) as well as Hadoop users (job analytics). The talk will also touch upon Ambari`s REST API and how it is used in the real world. The session concludes by revealing the future roadmap of Ambari including queue management, upgrade, disaster recovery, high availability, and more.

AUSPC 2013 - Business Continuity Management in SharePoint

Michael Noel

Providing for a highly available and disaster-tolerant SharePoint environment is no small task; as there are multiple components that require backup, and various architectural design options that each provide for various degrees of business continuity. Consequently, understanding how to design and implement a BCM solution for SharePoint is a must. This session covers BCM for SharePoint, including a thorough discussion of SharePoint Backup and Restore options, a discussion of various BCM-related architectural designs, and a frank look at some of the new SQL 2012 AlwaysOn options for SharePoint.

IoT Predictions for 2019 and Beyond: Data at the Heart of Your IoT Strategy

Hortonworks

Forrester forecasts* that direct spending on the Internet of Things (IoT) will exceed $400 Billion by 2023. From manufacturing and utilities, to oil & gas and transportation, IoT improves visibility, reduces downtime, and creates opportunities for entirely new business models. But successful IoT implementations require far more than simply connecting sensors to a network. The data generated by these devices must be collected, aggregated, cleaned, processed, interpreted, understood, and used. Data-driven decisions and actions must be taken, without which an IoT implementation is bound to fail. https://hortonworks.com/webinar/iot-predictions-2019-beyond-data-heart-iot-strategy/

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.
