OSCON 2013 - Planning an OpenStack Cloud - Tom FifieldOSCON Byrum
The flexibility of OpenStack is a dual-edged sword, giving you unprecedented control over your infrastructure, but potentially becoming a nightmare for the indecisive manager, architect or sysadmin!
In this presentation, Tom Fifield – co-author of the OpenStack Operations Guide, and Community Manager at the OpenStack Foundation – takes you through some of the decisions you will face when planning your OpenStack cloud. In addition to a brief introduction on OpenStack and advice on how to interact with the community, he will cover topics such as:
How to approach your deployment, ranging from DIY to a turn-key solution from the ecosystem
Storage and networking decisions, including plugin options
Automating deployment and configuration with popular tools like Puppet and Chef
Through discussion of the ecosystem, customization and scaling, you’ll walk away with an understanding of ‘what it takes’ to build your OpenStack cloud.
Give Your Confluent Platform Superpowers! (Sandeep Togrika, Intel and Bert Ha...HostedbyConfluent
Whether you are a die-hard DC comic enthusiast, mad for Marvel, or completely clueless when it comes to comic books, at the end of the day each of us would love to possess the superpower to transform data in seconds versus minutes or days. But architects and developers are challenged with designing and managing platforms that scale elastically and combine event streams with stored data, to enable more contextually rich data analytics. This made even more complex with data coming from hundreds of sources, and in hundreds of terabytes, or even petabytes, per day.
Now, with Apache Kafka and Intel hardware technology advances, organizations can turn massive volumes of disparate data into actionable insights with the ability to filter, enrich, join and process data instream. Let's consider Information Security. IT leaders need to ensure all company data and IP is secured against threats and vulnerabilities. A combination of real-time event streaming with Confluent Platform and Intel Architecture has enabled threat detection efforts that once took hours to be completed in seconds, while simultaneously reducing technical debt and data processing and storage costs.
In this session, Confluent and Intel architects will share detailed performance benchmarking results and new joint reference architecture. We’ll detail ways to remove Kafka performance bottlenecks, and improve platform resiliency and ensure high availability using Confluent Control Center and Multi-Region Clusters. And we’ll offer up tips for addressing challenges that you may be facing in your own super heroic efforts to design, deploy, and manage your organization’s data platforms.

Cloud computing transforms the way we can store, process and share our data. New applications and workloads are growing rapidly, which brings every day more sensitive data into the conversation about risk and what constitutes natural targets for bad actors. This presentation reflects on current best practices to address the most significant security concerns for sensitive data in the cloud, and offers participants a list of steps to achieve enterprise-grade safety with MongoDB deployments among the expanding service provider options.
