Philly ETE 2016 #9 – Srinivas Palthepu – Emergence of Real-Time Analytics: Real-time Analysis of Customer Financial Activities With Apache Flink

In this talk we present a business use case where Capital One needs to process customer activities real-time and react to events appropriately as needed. We then present our experience in building a real-time analytics application that serves the business using a set of open source software frameworks with Apache Flink at its core for real-time stream processing engine.

Philly ETE 2016 #6 – Sean Cribbs – Reliable High-Performance HTTP Infrastructure with nginx and Lua

We recently replaced a proprietary API management solution with an in-house implementation built with nginx and Lua that is more robust, higher performance, and has greater visibility. Learn about our development process and the overall architecture that allowed us to write high-level code while enjoying native code performance, and how we leveraged other open source tools like Vagrant, Ansible, and OpenStack to build an automation-rich delivery pipeline. We will also take an in-depth look at our capacity management approach that differs from the rate limiting concept prevalent in the API community.

Philly ETE 2016 #4 – Evan Chan – NoLambda: A new architecture combining streaming, ad hoc, machine learning, and batch analytics

In today’s world of exploding big and fast data, developers who want both streaming analytics and ad hoc, OLAP-like analysis have often had to develop complex architectures such as Lambda—a path for fast streaming analytics using NoSQL stores such as Cassandra and HBase with a separate batch path involving HDFS and Parquet. While this approach works, it involves too many moving parts, too many technologies for ops, and too many engineering hours. Helena Edelson and Evan Chan highlight a much simpler approach to combine streaming and ad hoc/batch analysis using what they call the NoLambda stack (Apache Spark/Scala, Mesos, Akka, Cassandra, Kafka), plus FiloDB, a new entrant to the distributed-database world that combines streaming and ad hoc analytics.

Philly ETE 2016 #3 – Diptanu Choudhury – Taming the Modern Private and Public Clouds with Nomad

In this talk, we will talk about the operational challenges of running a Cluster Scheduler to serve highly available services across multiple geographies and in a heterogeneous runtime environment. We will go into details of the needs from a cluster scheduler with respect to managing multiple runtime/virtualization platforms, provide observability, running maintenance on hardware and software, etc.

On today’s TechCast, Sujan Kapadia talks to yet another Scala person: James Roper (@jroper). Previously a core team member of the Play framework, James is now the tech lead of Lagom, a new Java-oriented micro-services framework introduced by Lightbend. He discusses it in depth in his ETE talk, Rethinking REST in a Microservices World, as well as in this conversation with Sujan.

Philly ETE 2016 #1 – Donn Felker – Realm – a New, Easy to Use Mobile Database & Object Framework

So you need to store data in your mobile application? Great, now you need to work with SQLite. Writing SQL is great fun if you enjoy thinking about mapping your objects to a relational store over and over and over. But what if there was another solution? One that allowed you to work with objects and store them as such with a powerful query system. No transformations back and forth to a relational store. Well, you’re in luck, one does exist: Realm. Realm is a mobile object (MVCC) database that can do all of these things and more. In this session learn how you can rid yourself of SQL, SQLite and its binding chains so you can harness the power and speed of working with native objects in Realm.

Philly ETE 2016 – Scott Ambler – Agility at Scale: Tactical and Strategic Approaches

This talk describes, step-by-step, how to evolve from today’s vision of agile software development to a truly disciplined agile enterprise. It briefly examines the state of mainstream agile software development and argues for the need for a more disciplined approach to agile delivery that provides a solid foundation from which to scale. It then explores what it means to scale disciplined agile strategies tactically at the project/product level and strategically across your IT organization as a whole. Your disciplined agile IT strategy, along with a lean business strategy, are key enablers of a full-fledged disciplined agile enterprise. The talk ends with advice for how to make this challenging organizational transition.
