This document discusses optimizations and updates to ELK logging in 2021. It covers the importance of logging, motivations for changes to improve logging, benefits to developers, and an overview of the multi-cluster logging architecture. Key points include faster log searches by indexing logs from different environments separately, automatic log shipping setup, cleaner log formats, and enabling log correlation and conversion to metrics. The logging flow involves Filebeat selecting logs and metadata, Logstash parsing and aggregating logs, Elasticsearch storing logs in indices, and Kibana for visualization and analysis.
Kubernetes-native or not? When should you ditch your traditional CI/CD server...Red Hat Developers
With the Kubernetes ecosystem growing and getting more popular every day, software teams are increasingly considering Kubernetes-native tools to develop applications, build/deploy images, and for monitoring/logging etc. This session will talk about Tekton – a Kubernetes-native CI/CD tool to build and deploy your code. The session will also discuss when to make that jump from a traditional CI/CD server, and more importantly, when not to. The session content will be a mix of conceptual information and demonstration.
Stefan is currently working on a new exciting project, GitOps Toolkit (https://github.com/fluxcd/toolkit), which is an experimental toolkit for assembling CD pipelines the GitOps way

Welcome Helm users! CNCF Flux has a best-in-class way to use Helm according to GitOps principles. For you, that means improved security, reliability, and velocity - no more being on the pager on the weekends or having painful troubleshooting or rollback when things go wrong. Built on Kubernetes controller-runtime, Flux’s Helm Controller is an example of a mature software agent that uses Helm’s SDK to full effect.
Flux’s biggest addition to Helm is a structured declaration layer for your releases that automatically gets reconciled to your cluster based on your configured rules:
⭐️ The Helm client commands let you imperatively do things
⭐️ Flux Helm Custom Resources let you declare what you want the Helm SDK to do automatically
During this session, Scott Rigby, Developer Experience Engineer at Weaveworks and Flux & Helm Maintainer, will take you on a tour of Flux’s Helm Controller, share the additional benefits Flux adds to Helm and then walk through a live demo of how to manage helm releases using Flux.
If you want to follow along with Scott’s demo, here are a couple of resources to help you prepare ahead of time:

Quarkus: From developer joy to Kubernetes nirvana! | DevNation Tech TalkRed Hat Developers
In a time where container image building tools outnumber application frameworks, and deployment descriptors are lengthier than a small app, "deployment" is the stage where developer fun goes to die. In a less dramatic tone: The options and complexity of containerizing and deploying an application is, to say the least, a distraction for most developers. But it doesn't have to be. Quarkus provides extensions that help developers eliminate those distractions by making smart choices for them and by integrating with the rest of the Quarkus ecosystem. This demonstration will show that in Quarkusland, Kubernetes is not a killjoy but part of the fun, by providing a concise experience as you mix and match support for various platforms (vanilla Kubernetes & OpenShift) with image building solutions (Docker, Jib & S2i).

Introduction: This session will cover learning about fundamentals of Apache Kafka and SMM (Streams Messaging Manager)
Format: This session will start with understanding the basic concepts/entities of Apache Kafka like Brokers, Topics, Producers and Consumers/Consumer Groups. It will then delve deeper in to advanced topics like idempotent producer, transactional API in Kafka for exactly once processing, authentication, authorization, replication, log compaction, compression, performance, etc. It will later on be followed by a demo of SMM, an open source Cloudera initiative to help users of Kafka get a better insight in to their Kafka clusters from an operational perspective using an elegant and slick GUI rather than writing complex manual scripts. It will also cover a demo of Alerting/Notification framework that can be used to trigger alerts and notify based on certain conditions one wants to monitor for.
Objective: The objective of this session is to learn about Apache Kafka and illustrate how SMM can help to answer questions that arise in production deployments. Example questions are “Do I have any offline topic partitions”, “Which consumer group is falling behind most”, “What producers are generating the most data right now”, “How does data in my application topic look like” and so on. It will also aim to get familiar with SMM GUI exploring different views around different entities like Brokers, Topics, Producers and Consumer Groups so that user can quickly look for valuable information needed to monitor Kafka clusters or their application. It will also aim to learn how to use the Alerting and Notification framework that comes with SMM to automate monitoring of Kafka clusters and the applications built around it.

Hierarchical Digital Twin of a Naval Power SystemKerry Sado
A hierarchical digital twin of a Naval DC power system has been developed and experimentally verified. Similar to other state-of-the-art digital twins, this technology creates a digital replica of the physical system executed in real-time or faster, which can modify hardware controls. However, its advantage stems from distributing computational efforts by utilizing a hierarchical structure composed of lower-level digital twin blocks and a higher-level system digital twin. Each digital twin block is associated with a physical subsystem of the hardware and communicates with a singular system digital twin, which creates a system-level response. By extracting information from each level of the hierarchy, power system controls of the hardware were reconfigured autonomously. This hierarchical digital twin development offers several advantages over other digital twins, particularly in the field of naval power systems. The hierarchical structure allows for greater computational efficiency and scalability while the ability to autonomously reconfigure hardware controls offers increased flexibility and responsiveness. The hierarchical decomposition and models utilized were well aligned with the physical twin, as indicated by the maximum deviations between the developed digital twin hierarchy and the hardware.

Cosmetic shop management system project report.pdfKamal Acharya
Buying new cosmetic products is difficult. It can even be scary for those who have sensitive skin and are prone to skin trouble. The information needed to alleviate this problem is on the back of each product, but it's thought to interpret those ingredient lists unless you have a background in chemistry.
Instead of buying and hoping for the best, we can use data science to help us predict which products may be good fits for us. It includes various function programs to do the above mentioned tasks.
Data file handling has been effectively used in the program.
The automated cosmetic shop management system should deal with the automation of general workflow and administration process of the shop. The main processes of the system focus on customer's request where the system is able to search the most appropriate products and deliver it to the customers. It should help the employees to quickly identify the list of cosmetic product that have reached the minimum quantity and also keep a track of expired date for each cosmetic product. It should help the employees to find the rack number in which the product is placed.It is also Faster and more efficient way.
Water scarcity is the lack of fresh water resources to meet the standard water demand. There are two type of water scarcity. One is physical. The other is economic water scarcity.

1. Logging – the crucial part !
Clearly states that:
- Applications should not attempt to write to / manage logsfiles
- Instead, each running process writes its event stream STDOUT
- During “local development”: observe on the terminal
- During “staging/production”:
Capture & collected by agents.
Then, routed to one final destination for viewing & long-term archival.

4. Multi-cluster logging architecture
4.1 Logging basic
Filebeat:
- Select messages for shipping (/var/logs/container/*.log)
- Select fields for shipping along with msg (kubernetes.namespace/imageVersion,…)
- Enrich msg with additional metadata (env, service_name, rename fields)
- Message processing AMAP to reduce workload for Logstash
Logstash:
- Drop more fields that can not removed at Filebeat level
- Using built-in module to parse specific log type (NGINX log)
- Log aggregator & sent to Elasticsearch for storage
ElasticSearch:
- Messages allocated to indices
- Index retention by ILM (Index Lifecyle Management)
Kibana:
- Visualization & Analysis
