Joining hands to fight COVID19

Friends,

Fighting the nCOV-2 virus needs lots of computing. Folding@home (https://foldingathome.org/) is a novel distributed computing project running out of Washington University. The aim of the project is to create programs which Internet users can install on their personal computers and share their computing cycles and contribute in solving protein folding problems associated with COVID19 and other similar virus research, specially towards drug design. More details on how to participate is available here : https://foldingathome.org/start-folding/ .

While you add our personal computer, laptop to this novel work, please join the “Large Scale Production Engineering India Meetup Forum” team. Our team number is : 266344. Let us jointly win this war !

Friends,

The community is meeting today for its 32nd event (first virtual) over a Zoom video conference sponsored by Grab. Those who did not RSVP and would like to watch, please follow live stream here : https://www.youtube.com/watch?v=2Y8AaCsOTY8

Friends,

Humanity is passing through difficult times. COVID19 is keeping communities like ours constrained from undertaking regular meets. We postponed our 32nd event, scheduled earlier in March. We expected the situation to improve. However it's taking more than our expectation. It's high time we act to meet again, this time virtually. We are scheduled to meet for our first virtual meetup, next Saturday, 9th May 2020. More about joining modalities coming shortly. Please keep watching this space.

11:00 - Tea

11:15 - Opening and stage setting for 15th event.

11:30 - Simoorg: Failure Simulation using python in a cluster for testing the   stability of the code - Arjun Shenoy is a Site Reliability Engineer at LinkedIn India   Abstract : Simoorg the new failure simulation tool developed at LinkedIn.   It is a failure induction tool (similar to chaos monkey) . The main rationale behind developing the tool was to have an extensible and easy to   code framework for inducing failures. Failure Inducer works by introducing a particular set of failures to a healthy cluster and then reverting them after a period of time during which it the state of the cluster is logged. The talk is going to cover introduction to Simoorg, its key features that separates it from chaos monkey architecture and a demo. git url :​ https://github.com/linkedin/simoorg   About Arjun : https://in.linkedin.com/in/arjunshenoylinkedin  

12:15 - What is Your Monitoring Strategy - Aveek Misra , Devops Architect, Intuit  

In this talk Aveek would discuss about how the monitoring strategy has evolved given the changes in web applications and infrastructure. With the advent of public and private clouds and containers, the old notions of infrastructure monitoring are no longer that useful. The application landscape has also changed with monolith applications being split up into micro services and written in languages such as Node.js. Also many of the companies today are “Mobile First” which means that the monitoring of apps in mobile devices has now become very important. My talk will focus on some of these changes that are taking place in the monitoring landscape today and how your monitoring strategy should factor this in while setting up your monitoring.

Aveek is a DevOps architect in Intuit with more than 16 years of experience. For the past 6 years, I have been working in the Monitoring domain. In my past experience working with Yahoo, I have been very fortunate being part of the development team that created a highly scalable monitoring platform.

1:00 - Lunch

2:00 - Java 8 - New APIs and simplified parallelism- Deepak Shiwani, SDE3, Flipkart

Introduced in 1995, Java is programming language of choice for 9 million developers and today powers 7 billion devices. In March 2014, Oracle announced availability of Java SE 8, and we will see Java SE 9, released in 2016. Despite being in market for around 20 months, developers have not started extracting the best out of new features in Java 8 like lambdas, default methods, functional interfaces, streams apis etc.   In this talk, Deepak will start discussing about these new features specifically - the new streams API and ability to make the code parallel to utilize all the cores on the hardware more efficiently. Parallel programming was always there in Java prior to Java 8, but it involved lot of boiler plate code around Threads, Executors etc, but with Java 8, all this has been made easy. A more appealing reason to make your code faster. The session will include demo for sample code, written in traditional manner and then making it parallel using Java 8 constructs and that too - with minimal coding.

Deepak Shevani is SDE 3 at Flipkart, and works with teams building next generation of e-commerce platforms. Prior to Flipkart, he has worked at Yahoo as part of search team, where his focus areas were image and video search algorithms. He is keen to meet folks across industry and share insights about the trends and upcoming technologies.

Announcing the Next Quarterly LSPE Meetup - Q3 2015

LSPE-IN in collaboration with Devops Bangalore Meetup community is proud to present the next edition of our quarterly meeting    When: Saturday, September 12, 2015 10:30 AM    Where: Yahoo Software Development India Pvt Ltd.,“Torrey Pines”, Embassy Golf Links Business Park, Off Indiranagar- Koramangala  Intermediate Ring Road, Domlur, Bangalore

Event Agenda and Speaker info

10:45 - Registration 11:00 - Tea 11:15 - Opening Note : Measuring Computing - how lspe-in can partner with CMG and build a stronger community - Milind Hanchinmani 11:30 - Experience of designing a NoSQL backend for Keystone (Authorization and authentication component of Openstack) - Ajaya Agrawal, Devops, Reliance

Abstract: OpenStack Identity, or Keystone, is the project that provides authentication and authorization for use by all projects in the OpenStack family. It provides the APIs and the backing implementation to manage key areas such as identity, resources, and assignment. The default backend for persisting data for this purpose is MySQL, deployed either in a master-slave mode, or multi-master mode. In master-slave mode, the master is a single-point-of-failure. Moreover, the slaves are eventually consistent with the master due to the replication lag. A multi-master deployment such as that offered by Galera, improves availability as well as request handling capacity. The price incurred for this improvement is the increased latencies for every write. Moreover, this solution only scales up to the capacity of a single node, but does not scale out. To help with large deployments, we added an optional NoSQL backend based on Cassandra to address both concerns of single-point-of-failure, and lack of ability to scale-out.

12:15 - Azkaban-Scheduling Hadoop and BigData jobs - Arpit Tak, Software Engineer ,  Vizury

Sakthivel is working as a Senior Systems Engineer at Yahoo handling critical properties like Frontpage and News

3:00 - Taming Graphite for a million metrics a minute - Jaseer T. K , Senior Operations Engg, InMobi
