In software engineering, the right architecture is essential for robust, scalable platforms. Wix has undergone a pivotal shift from event sourcing to a CRUD-based model for its microservices. This talk will chart the course of this pivotal journey.
Event sourcing, which records state changes as immutable events, provided robust auditing and "time travel" debugging for Wix Stores' microservices. Despite its benefits, the complexity it introduced in state management slowed development. Wix responded by adopting a simpler, unified CRUD model. This talk will explore the challenges of event sourcing and the advantages of Wix's new "CRUD on steroids" approach, which streamlines API integration and domain event management while preserving data integrity and system resilience.
Participants will gain valuable insights into Wix's strategies for ensuring atomicity in database updates and event production, as well as caching, materialization, and performance optimization techniques within a distributed system.
Join us to discover how Wix has mastered the art of balancing simplicity and extensibility, and learn how the re-adoption of the modest CRUD has turbocharged their development velocity, resilience, and scalability in a high-growth environment.
First Steps with Globus Compute Multi-User EndpointsGlobus
In this presentation we will share our experiences around getting started with the Globus Compute multi-user endpoint. Working with the Pharmacology group at the University of Auckland, we have previously written an application using Globus Compute that can offload computationally expensive steps in the researcher's workflows, which they wish to manage from their familiar Windows environments, onto the NeSI (New Zealand eScience Infrastructure) cluster. Some of the challenges we have encountered were that each researcher had to set up and manage their own single-user globus compute endpoint and that the workloads had varying resource requirements (CPUs, memory and wall time) between different runs. We hope that the multi-user endpoint will help to address these challenges and share an update on our progress here.

Climate Science Flows: Enabling Petabyte-Scale Climate Analysis with the Eart...Globus
The Earth System Grid Federation (ESGF) is a global network of data servers that archives and distributes the planet’s largest collection of Earth system model output for thousands of climate and environmental scientists worldwide. Many of these petabyte-scale data archives are located in proximity to large high-performance computing (HPC) or cloud computing resources, but the primary workflow for data users consists of transferring data, and applying computations on a different system. As a part of the ESGF 2.0 US project (funded by the United States Department of Energy Office of Science), we developed pre-defined data workflows, which can be run on-demand, capable of applying many data reduction and data analysis to the large ESGF data archives, transferring only the resultant analysis (ex. visualizations, smaller data files). In this talk, we will showcase a few of these workflows, highlighting how Globus Flows can be used for petabyte-scale climate analysis.
We describe the deployment and use of Globus Compute for remote computation. This content is aimed at researchers who wish to compute on remote resources using a unified programming interface, as well as system administrators who will deploy and operate Globus Compute services on their research computing infrastructure.

Understanding Globus Data Transfers with NetSageGlobus
NetSage is an open privacy-aware network measurement, analysis, and visualization service designed to help end-users visualize and reason about large data transfers. NetSage traditionally has used a combination of passive measurements, including SNMP and flow data, as well as active measurements, mainly perfSONAR, to provide longitudinal network performance data visualization. It has been deployed by dozens of networks world wide, and is supported domestically by the Engagement and Performance Operations Center (EPOC), NSF #2328479. We have recently expanded the NetSage data sources to include logs for Globus data transfers, following the same privacy-preserving approach as for Flow data. Using the logs for the Texas Advanced Computing Center (TACC) as an example, this talk will walk through several different example use cases that NetSage can answer, including: Who is using Globus to share data with my institution, and what kind of performance are they able to achieve? How many transfers has Globus supported for us? Which sites are we sharing the most data with, and how is that changing over time? How is my site using Globus to move data internally, and what kind of performance do we see for those transfers? What percentage of data transfers at my institution used Globus, and how did the overall data transfer performance compare to the Globus users?
1. 1. Hadoop Tutorial
The Hadoop tutorial is a comprehensive guide on Big Data Hadoop that
covers what is Hadoop, what is the need of Apache Hadoop, why Apache
Hadoop is most popular, How Apache Hadoop works?
Apache Hadoop is an open source, Scalable, and Fault tolerant framework
written in Java. It efficiently processes large volumes of data on a cluster
of commodity hardware. Hadoop is not only a storage system but is a
platform for large data storage as well as processing. This Big Data
Hadoop tutorial provides a thorough Hadoop introduction.
We will also learn in this Hadoop tutorial about Hadoop architecture,
Hadoop daemons, different flavors of Hadoop. At last, we will cover the
introduction of Hadoop components like HDFS, MapReduce, Yarn, etc.
Introduction to Hadoop Tutorial
2. What is Hadoop Technology?
Hadoop is an open-source tool from the ASF – Apache Software
Foundation. Open source project means it is freely available and we can
even change its source code as per the requirements. If certain
functionality does not fulfill your need then you can change it according to
2. your need. Most of Hadoop code is written by Yahoo, IBM, Facebook,
Cloudera.
It provides an efficient framework for running jobs on multiple nodes of
clusters. Cluster means a group of systems connected via LAN. Apache
Hadoop provides parallel processing of data as it works on multiple
machines simultaneously. Lets see a video Hadoop Tutorial to understand
what is Hadoop in a better way.
Learn: How Hadoop Works?
Big Data Hadoop Tutorial Video
Hope the above Big Data Hadoop Tutorial video helped you. Let us see
further.
By getting inspiration from Google, which has written a paper about the
technologies. It is using technologies like Map-Reduce programming
model as well as its file system (GFS). As Hadoop was originally written
for the Nutch search engine project. When Doug Cutting and his team
were working on it, very soon Hadoop became a top-level project due to
its huge popularity. Let us understand Hadoop Defination and Meaning.
Apache Hadoop is an open source framework written in Java. The basic
Hadoop programming language is Java, but this does not mean you can
code only in Java. You can code in C, C++, Perl, Python, ruby etc. You
can code the Hadoop framework in any language but it will be more good
to code in java as you will have lower level control of the code.
Big Data and Hadoop efficiently processes large volumes of data on a
cluster of commodity hardware. Hadoop is for processing huge volume of
data. Commodity hardware is the low-end hardware, they are cheap
devices which are very economical. Hence, Hadoop is very economic.
Hadoop can be setup on a single machine (pseudo-distributed mode, but it
shows its real power with a cluster of machines. We can scale it to
thousand nodes on the fly ie, without any downtime. Therefore, we need
not make any system down to add more systems in the cluster. Follow this
guide to learn Hadoop installation on a multi-node cluster.
3. Hadoop consists of three key parts –
Hadoop Distributed File System (HDFS) – It is the storage layer of
Hadoop.
Map-Reduce – It is the data processinglayer of Hadoop.
YARN – It is the resource management layer of Hadoop.
In this Hadoop tutorial for beginners we will all these three in detail, but
first lets discuss the significance of Hadoop.
3. Why Hadoop?
Let us now understand in this Hadoop tutorial that why Big Data Hadoop
is very popular, why Apache Hadoop capture more than 90% of big
data market.
Apache Hadoop is not only a storage system but is a platform for data
storage as well as processing. It is scalable (as we can add more nodes on
the fly), Fault tolerant(Even if nodes go down, data processed by another
node).
Following characteristics of Hadoop make it a unique platform:
Flexibilityto store and mine anytype of data whether it is
structured,semi-structured orunstructured.It is not bounded bya
single schema.
Excels at processing data of complex nature.Its scale-out
architecture divides workloads across manynodes.Another added
advantage is that its flexible file-system eliminates ETLbottlenecks.
Scales economically,as discussed it can deployon commodity
hardware.Apart from this its open-source nature guards against
vendorlock.
Learn Hadoop features in detail.
4. What is Hadoop Architecture?
4. After understanding what is Apache Hadoop, let us now understand the
Big Data Hadoop Architecture in detail in this Hadoop tutorial.
Learn Hadoop from Industry Experts
Hadoop Tutorial – Hadoop Architecture
Hadoop works in master-slave fashion. There is a master node and there
are n numbers of slave nodes where n can be 1000s. Master manages,
maintains and monitors the slaves while slaves are the actual worker
nodes. In Hadoop architecture the Master should deploy on good
configuration hardware, not just commodity hardware. As it is the
centerpiece of Hadoop cluster.
Master stores the metadata (data about data) while slaves are the nodes
which store the data. Distributedly data stores in the cluster. The client
connects with master node to perform any task. Now in this Hadoop for
beginners tutorial for beginners we will discuss different components of
Hadoop in detail.
5. Hadoop Components
There are three most important Apache Hadoop Components. In this
Hadoop tutorial, you will learn what is HDFS, what is Hadoop
MapReduce and what is Yarn Hadoop. Let us discuss them one by one-
5.1. What is HDFS?
Hadoop HDFS or Hadoop Distributed File System is a distributed file
system which provides storage in Hadoop in a distributed fashion.
In Hadoop Architecture on the master node, a daemon
called namenode run for HDFS. On all the slaves a daemon
called datanode run for HDFS. Hence slaves are also calledas datanode.
Namenode stores meta-data and manages the datanodes. On the
other hand, Datanodes stores the data and do the actual task.
Hadoop Tutorial – Hadoop HDFS Architecture
5. HDFS is a highly fault tolerant, distributed, reliable and scalable file
system for data storage. First Follow this guide to learn more about
features of HDFS and then proceed further with the Hadoop tutorial.
HDFS is developed to handle huge volumes of data. The file size expected
is in the range of GBs to TBs. A file is split up into blocks (default 128
MB) and stored distributedly across multiple machines. These
blocks replicate as per the replicationfactor. After replication, it stored at
different nodes. This handles the failure of a node in the cluster. So if there
is a file of 640 MB, it breaks down into 5 blocks of 128 MB each (if we
use the default value).
5.2. What is MapReduce?
In this Hadoop Basics Tutorial, now its time to understant one of the most
important pillar if Hadoop, i.e. Hadoop MapReduce. The Hadoop
MapReduce is a programming model. As it is designed for large volumes
of data in parallel by dividing the work into a set of independent tasks.
MapReduce is the heart of Hadoop, it moves computation close to the
data. As a movement of a huge volume of data will be very costly. It
allows massive scalabilityacross hundreds or thousands of servers in
a Hadoop cluster.
Hence, Hadoop MapReduce is a framework for distributed processing of
huge volumes of data set over a cluster of nodes. As data stores in a
distributed manner in HDFS. It provides the way to Map–Reduce to
perform parallel processing.
5.3. What is YARN Hadoop?
YARN – Yet Another Resource Negotiator is the resource management
layer of Hadoop. In the multi-node cluster, as it becomes very complex to
manage/allocate/release the resources (CPU, memory, disk). Hadoop
Yarn manages the resources quite efficiently. It allocates the same on
request from any application.
On the master node, the ResourceManager daemon runs for the YARN
then for all the slave nodes NodeManager daemon runs.

6. Hadoop Daemons
Daemons are the processes that run in the background. There are
mainly 4 daemons which run for Hadoop.
Hadoop Daemons
Namenode – It runs on master node for HDFS.
Datanode – It runs on slavenodes for HDFS.
ResourceManager – It runs on master node for Yarn.
NodeManager – It runs on slave node for Yarn.
These 4 demons run for Hadoop to be functional. Apart from this, there
can be secondary NameNode, standby NameNode, Job HistoryServer, etc.
7.’How do Hadoop works?’
Till now in Hadoop training we have studied Hadoop Introduction and
Hadoop architecture in detail. Now next Let us summarize
Apache Hadoop working step by step:
i) Input data breaks into blocks of size 128 Mb (by default) and then
moves to different nodes.
ii) Once all the blocks of the file stored on datanodes then a user can
process the data.
iii) Then, master schedules the program (submitted by the user) on
individual nodes.
iv) Once all the nodes process the data then the output is written back
to HDFS.
8. Hadoop Flavors
7. This section of Hadoop Tutorial talks about the various flavors of Hadoop.
Apache – Vanilla flavor,as the actual code is residing
in Apache repositories.
Hortonworks – Populardistribution in the industry.
Cloudera – It is the most popularin the industry.
MapR – It has rewritten HDFS and its HDFS is faster as compared to
others.
IBM – Proprietarydistributionis known as Big Insights.
All the databases have provided native connectivity with Hadoop for fast
data transfer. Because, to transfer data from Oracle to Hadoop, you need a
connector.
All flavors are almost same and if you know one, you can easily work on
other flavors as well.
9. Hadoop Ecosystem Components
In this section of Hadoop tutorial, we will cover Hadoop ecosystem
components. Let us see what all the components form the Hadoop Eco-
System:
Hadoop Tutorial – Hadoop Ecosystem Components
Hadoop HDFS – Distributed storage layer for Hadoop.
Yarn Hadoop – Resource management layer introduced in Hadoop
2.x.
Hadoop Map-Reduce – Parallel processinglayer for Hadoop.
HBase – It is a column-oriented database that runs on top of HDFS.
It is a NoSQL database which does not understandthe structured
query. For sparse data set, it suits well.
Hive – Apache Hive is a data warehousinginfrastructure based on
Hadoop and it enables easydata summarization,usingSQL queries.
Pig – It is a top-level scriptinglanguage.As we use it with
Hadoop. Pig enables writingcomplex data processingwithout Java
programming.
Flume – It is a reliable system for efficientlycollectinglarge
amounts oflog data from manydifferent sources in real-time.
8. Sqoop – It is a tool design to transport huge volumes of data
between Hadoop and RDBMS.
Oozie – It is a Java Web application uses to schedule Apache
Hadoop jobs.It combines multiple jobs sequentiallyinto one logical
unit of work.
Zookeeper – A centralized service for maintainingconfiguration
information,naming,providingdistributed synchronization,and
providinggroup services.
Mahout – A libraryof scalable machine-learningalgorithms,
implemented on top of Apache Hadoop and usingthe MapReduce
paradigm.
Refer this Hadoop Ecosystem Components tutorial for the detailed study
of All the Ecosystem components of Hadoop.
So, This was all about the Hadoop Tutorial.
10. Conclusion: Hadoop Tutorial
In conclusion to this Big Data tutorial, we can say that Apache Hadoop is
the most popular and powerful big data tool. Big Data stores huge amount
of data in the distributed manner and processes the data in parallel on a
cluster of nodes. It provides world’s most reliable storage layer- HDFS.
Batch processing engine MapReduce and Resource management layer-
YARN. 4 daemons (NameNode, datanode, node manager, resource
manager) run in Hadoop to ensure Hadoop functionality.
