Eduardo Silva is an open source engineer at Treasure Data who works on Fluentd and FluentBit projects. FluentBit is a lightweight log collector for embedded Linux applications and IoT devices. It has built-in system metrics collection and supports custom inputs and outputs using msgpack serialization. FluentBit integrates with Fluentd for log aggregation and is designed to have low resource usage for constrained environments. The roadmap includes adding a library mode and more supported sensors.
Scaling the logging pipeline requires better understanding of each phase behind the scenes.
Everything about Fluentd as an aggregator and Fluent Bit as it Log Forwarder
Presentation at LinuxCon Europe 2016 (Berlin). I introduced the concepts of logging for containers, aggregation patterns, distributted logging, data serialization, Fluentd: internals, architecture, Fluent Bit and it library API.

Virtual Flink Forward 2020: Build your next-generation stream platform based ...Flink Forward
As organizations are getting better at capturing streaming data and the data velocity and volume are ever-increasing, the traditional messaging queues or log storage systems are suffering from scalability or operational and maintenance problems. Apache Pulsar is a multi-tenant, high-performance distributed pub-sub messaging system. Pulsar includes multiple features, such as native support for multiple clusters in a Pulsar instance, seamless geo-replication of messages across clusters, very low publishing and end-to-end latency, seamless scalability to over a million topics, and guaranteed message delivery with persistent message storage provided by Apache BookKeeper. In this talk, I will use one of the most popular stream processing engines, Apache Flink, as an example, to share our experience in building a stream processing and storage stack. Some of the traits are: * How to ensure end-to-end exactly-once semantics based on Pulsar's durable and replayable storage as well as Pulsar transaction. * How to implement Pulsar topics as infinite tables based on Pulsar's schema. * How to efficiently store stream states in Pulsar based on Pulsar's layered storage API. * A usage scenario that chaining all functionalities in the streaming platform.

A retrospective on the state of the development of the Kong API Gateway since its 1.0 release. New features, new deployment paradigms, and what to expect from upcoming releases. This talk was given at the AWS Loft Tokyo on April 16th, 2019.
Modern software development is increasingly taking a “microservice” approach that has resulted in an explosion of complexity at the network level. We have more applications running distributed across different datacenters. Distributed tracing, events, and metrics are essential for observing and understanding modern microservice architectures.
This talk is a deep dive on how to monitor your distributed system. You will get tools, methodologies, and experiences that will help you to realize what your applications expose and how to get value out from all these information.
Gianluca Arbezzano, SRE at InfluxData will share how to monitor a distributed system, how to switch from a more traditional monitoring approach to observability. Stay focused on the server’s role and not on the hostname because it’s not really important anymore, our servers or containers are fast moving part and it’s easy to detach it from the right in case of trouble than call the server by name as a cute puppet. How to design a SLO for your core services and now to iterate on them. Instrument your services with tracing using tools like Zipkin or Jaeger to measure latency between in your network.

Modern deployment and hosting environments have created a new dynamism to application, network, and development architectures. Compute resources are ephemeral, networks are instantiated and configured with API calls, and new versions of applications are deployed in seconds... security has not met this challenge gracefully. In this talk, we explore some new and interesting ways to make security reactive within cloud environments by dynamically changing the environment in response to and in preparation for security incidents, baby steps toward an architecture that can protect itself.
IM World presentation from Chris Swan: Application centric – how the cloud ha...Cohesive Networks
Chris Swan, CTO at Cohesive Networks presented the talk "Application centric – how the cloud has changed the way we deploy, secure and connect" at IM World 2015.
Day 2, on the Business Software Stage.
About the talk:
The cloud has brought a new model for how we deploy applications. In the enterprise everything was put on the same network, ‘the intranet’. People claimed that things were safe there because they were, ‘behind the firewall’. It was easy to build a spaghetti of interconnections because everything could talk to everything. Cloud has changed all of that. At first it was just lonely virtual machines fending for themselves on the Internet, but now we have virtual private clouds (VPCs) and a multitude of ways to connect to them. Pretty much nobody has built a cloud intranet. The cloud is used to host applications, and each application gets its own security and connectivity. We’re moving to an application centric world.

Automated Infrastructure Security: Monitoring using FOSSSonatype
Madhu Akula, Automation Ninja
We can see attacks happening in real time using a dashboard. By collecting logs from various sources we will monitor & analyse. Using data gleaned from the logs, we can apply defensive rules against the attackers. We will use AWS for managing and securing the infrastructure discussed in our talk.
For most network engineers who monitor the perimeter for malicious content, it is very important to respond to an imminent threat originating from outside the boundaries of their network. Having to crunch through all the logs that the various devices (firewalls, routers, security appliances etc.) spit out, correlating that data and in real time making the right choices can prove to be a nightmare. Even with the solutions already available in the market.
As I have experienced this myself, as part of the Internal DevOps and Incident Response Teams, in several cases, I would want to create a space for interested folks to design, build, customise and deploy their very own FOSS based centralised visual attack monitoring dashboard. This setup would be able to perform real time analysis using the trusted ELK stack and visually denote what popular attack hotspots exist on a network.

From leading IoT Protocols to Python Dashboarding_finalLukas Ott
First i like to give an overview on common IoT Protocols:
#CoAP (Constrained Application Protocol -> Close to HTTP / REST ) #MQTT ( Message Queue Telemetry Transport -> Pub/Sub with Broker -> Well defined Quality of Service -> Newest addition Eclipse Amlem (formerly the core of IBM Watson IoT platform) -> Eclipse Sparkplug -> Standardization of the topics and payloads -> Interoperability!) , #DDS (Data Distribution Service -> Pub/Sub without Broker -> Drones / Robotics) #LwM2M (Lightweight M2M -> Runs on Top of CoAP or MQTT -> standard sets of payloads for sensors) #zenoh (https://zenoh.io/ Pub/Sub Protocol -> combines the advantages of #DDS and #MQTT) #eclipsefoundation #apache #opensource #lightweight (+ some comments that this is not complete and does not encompass Industrial and Building Automation)
Then I would like to show the leading edge IoT protocol Zenoh. Saving Zenoh Payload to Apache IoTDB. After that I would like to dive into Panel and the awesome capabilities of Apache ECharts.

Courier management system project report.pdfKamal Acharya
It is now-a-days very important for the people to send or receive articles like imported furniture, electronic items, gifts, business goods and the like. People depend vastly on different transport systems which mostly use the manual way of receiving and delivering the articles. There is no way to track the articles till they are received and there is no way to let the customer know what happened in transit, once he booked some articles. In such a situation, we need a system which completely computerizes the cargo activities including time to time tracking of the articles sent. This need is fulfilled by Courier Management System software which is online software for the cargo management people that enables them to receive the goods from a source and send them to a required destination and track their status from time to time.
