Abstract:
Continuous delivery is everywhere. Well, not quite! Many teams still fail to continuously deliver well tested and stable product increments to production, especially when it comes to its non-functional attributes. Usually with the same old excuse: these high-level tests are too laborious and expensive to implement. But the opposite could be the case! This slides will show how easy it is to implement continuous performance, security and acceptance tests based for microservices on Kubernetes using well-known open source tools.
Changing application demands: What developers need to knowIndicThreads
Due to the demands of our hyper-connected, Internet-driven economy, users expect speedy delivery of new features, highly engaging personalized user experiences, and smooth, streamlined performance. The result is that best practices for application development and architecture are rapidly changing.
Traditional approaches to development are no longer competitive, with the new focus on simplicity, usability, and large-scale DevOps agility. In order to thrive, development teams must adjust to deliver high-quality applications fast.
This keynote will discuss:
The traditional monolith application vs. the modern application.
Architectural considerations for the modern application.
How trends such as DevOps and microservices affect application design.
Tools, technologies, and techniques for building modern applications.

[WSO2 API Day Chicago 2019] Sustainable Competitive Advantage WSO2
Sustainable competitive advantage, while once a necessary part of any strategy, is now increasingly obsolete for most firms. The new path to winning means capturing opportunities quickly and exploiting them decisively. It's all about learning to thrive in a transient advantage economy. Transient advantage is the central thesis of Rita McGrath's recent book on competitive advantage. These principles are especially relevant for agile companies that pursue digital-first business models. Quinnox has adopted this philosophy for its clients and its own business where we believe enterprise integration driven by API's is the bridge to digital transformation, speed to market, and frequency to market.

Scaling Your Architecture for the Long TermRandy Shoup
This talk from the virtual 2020 CTO Summit (https://www.ctoconnection.com/summits) covers several architecture lessons to help you survive and thrive through the scaling phase of your company:
* Modular Architecture
* Event-Driven Communication
* Quality and Reliability
* Continuous Delivery
Apex Triggers can be your best friend or your worst enemy. When a trigger is firing properly your data is under control and remains sane, but when a trigger doesn't fire properly, your users can be faced with the frustration of exceptions when saving a record, or worse: incorrect data. Join us to learn tips and tricks on how to debug and solve the most complex issues, including: Ambiguous Field Validation, After Insert Activity Errors, and SOQL and Governor Limit Errors. You'll learn the origins of these kinds of advanced trigger issues and gain solutions for avoiding them.
Microservices are a well-established architecture applied by many organizations around the world to build scalable and fault-tolerant backend systems. But as these systems grow so does the number of services in them. And this brings many challenges when we want to introduce new functionality. For a simple feature, engineers may need to spend a lot of time designing the end to end flow, changing code in multiple services and setting up complex test scenarios. During this talk, we’ll explore how to evolve a microservice architecture to be easily extensible based on some lessons learned from running 5000 microservices in production. We’ll go over different architectural patterns and open source tools that we can use to make it easy for all engineers to understand, extend and be more and more productive in such big complex systems.
The introduction of microservices, Node.js, Cloud Foundry, Docker containers, etc. are adding a new layer of complexity to an already complex application environment. When application issues arise, it becomes difficult to pinpoint the source and, too often, you find yourself in lengthy war rooms or assigning experts to triage every issue. As a result, brand loyalty, customer satisfaction and innovation are negatively impacted. The old approach to application performance management just isn’t working. A new approach is needed. In this session you will learn how to monitor these new modern applications to ensure the customer experience.

DevOps has landed and many organizations are now enjoying the promised benefits such as shorter times to market, more efficient delivery processes, great levels of innovation, and happier teams. But that isn’t the whole story. Sometimes these achievements are confined to limited numbers of perhaps digital or systems of engagement teams. Bringing the benefits to more challenging areas in the enterprise may be still pending. Growing pains may also be starting to emerge for example achieving the right balance between autonomous teams free to choose their own tools and ending up with too much sprawl and having missed the benefits of enterprise standards. Here are my own perspectives based on scaling DevOps adoption in Accenture and with our clients.

Extending Jenkins to the Mainframe. A Simpler Approach.DevOps.com
Wouldn’t it be great to use familiar tools when you’re needing to integrate mainframe applications into your DevOps pipeline?
Mainframe applications have historically required specialized tools and knowledge to build, maintain and integrate with distributed systems. Existing tool integrations are designed for vendor-specific tool chains and they require a great deal of specialized knowledge and expertise to set up.
CA Technologies engineering decided to break with tradition and utilize advancements on the zOS platform to provide a Command Line Interface that turns Mainframe into “just” another deployment target for the DevOps pipeline.
In this webinar the presenters will show how to integrate, build and test COBOL applications into a modern DevOps pipeline managed by Jenkins Continuous Integration software.

The annual review session by the AMIS team on their findings, interpretations and opinions regarding news, trends, announcements and roadmaps around Oracle's product portfolio.
Since JDK 9, G1 GC is the default garbage collector (JEP 248). Up until 2017, Monica has shared some G1 GC details, performance tips, and optimizations that help G1's adaptiveness and provided advice on manual tuning.
Since then, G1 has come a long way in improving its adaptiveness. In this session, Monica will cover most of the important optimizations that are delivered from JDK9+ and how they can help your application's responsiveness, throughput, and help with footprint reduction. This is a saga that involves various regions and generations (all pun intended).
Are your application's tail-latencies holding it back from delivering its near-real time SLOs? Do your in-memory processing platform's long pauses only get worse with increasing heap sizes? How about those latency spikes causing variability in your end-to-end latency for your multi-tiered distributed systems?
If any of the above keep you up at night, then have no fear as Z Garbage Collector (GC) is here and is production ready in JDK 15.
In this talk, Monica Beckwith will cover the basics of Z GC and contrast it with G1 GC (the current default collector for OpenJDK JDK 11 LTS and tip).

Automobile Management System Project Report.pdfKamal Acharya
The proposed project is developed to manage the automobile in the automobile dealer company. The main module in this project is login, automobile management, customer management, sales, complaints and reports. The first module is the login. The automobile showroom owner should login to the project for usage. The username and password are verified and if it is correct, next form opens. If the username and password are not correct, it shows the error message.
When a customer search for a automobile, if the automobile is available, they will be taken to a page that shows the details of the automobile including automobile name, automobile ID, quantity, price etc. “Automobile Management System” is useful for maintaining automobiles, customers effectively and hence helps for establishing good relation between customer and automobile organization. It contains various customized modules for effectively maintaining automobiles and stock information accurately and safely.
When the automobile is sold to the customer, stock will be reduced automatically. When a new purchase is made, stock will be increased automatically. While selecting automobiles for sale, the proposed software will automatically check for total number of available stock of that particular item, if the total stock of that particular item is less than 5, software will notify the user to purchase the particular item.
Also when the user tries to sale items which are not in stock, the system will prompt the user that the stock is not enough. Customers of this system can search for a automobile; can purchase a automobile easily by selecting fast. On the other hand the stock of automobiles can be maintained perfectly by the automobile shop manager overcoming the drawbacks of existing system.

Laundry management system project report.pdfKamal Acharya
Laundry firms currently use a manual system for the management and maintenance of critical information. The current system requires numerous paper forms, with data stores spread throughout the laundry management infrastructure. Often information is incomplete or does not follow management standards. Records are often lost in transit during computation requiring a comprehensive auditing process to ensure that no vital information is lost. Multiple copies of the same information exist in the laundry firm data and may lead to inconsistencies in data in various data stores.
A significant part of the operation of any laundry firm involves the acquisition, management and timely retrieval of great volumes of information. This information typically involves; customer personal information and clothing records history, user information, price of delivery and received date, users scheduling as regards customers details and dealings in service rendered, also our products package waiting list. All of this information must be managed in an efficient and cost wise fashion so that the organization resources may be effectively utilized.
We present the design and implementation of a laundry database management system (LBMS) used in a laundry establishment. Laundry firms are usually faced with difficulties in keeping detailed records of customers clothing; this little problem as seen to most laundry firms is highly discouraging as customers are filled with disappointments, arising from issues such as customer clothes mix-ups and untimely retrieval of clothes. The aim of this application is to determine the number of clothes collected, in relation to their owners, as this also helps the users fix a date for the collection of their clothes. Also customer’s information is secured, as a specific id is allocated per registration to avoid contrasting information.
CFD Simulation of By-pass Flow in a HRSG module by R&R Consult.pptxR&R Consult
CFD analysis is incredibly effective at solving mysteries and improving the performance of complex systems!
Here's a great example: At a large natural gas-fired power plant, where they use waste heat to generate steam and energy, they were puzzled that their boiler wasn't producing as much steam as expected.
R&R and Tetra Engineering Group Inc. were asked to solve the issue with reduced steam production.
An inspection had shown that a significant amount of hot flue gas was bypassing the boiler tubes, where the heat was supposed to be transferred.
R&R Consult conducted a CFD analysis, which revealed that 6.3% of the flue gas was bypassing the boiler tubes without transferring heat. The analysis also showed that the flue gas was instead being directed along the sides of the boiler and between the modules that were supposed to capture the heat. This was the cause of the reduced performance.
Based on our results, Tetra Engineering installed covering plates to reduce the bypass flow. This improved the boiler's performance and increased electricity production.
It is always satisfying when we can help solve complex challenges like this. Do your systems also need a check-up or optimization? Give us a call!
Work done in cooperation with James Malloy and David Moelling from Tetra Engineering.

This project allows viewing various products available enables registered users to purchase desired products instantly using Paytm, UPI payment processor (Instant Pay) and also can place order by using Cash on Delivery (Pay Later) option. This project provides an easy access to Administrators and Managers to view orders placed using Pay Later and Instant Pay options.
In order to develop an e-commerce website, a number of Technologies must be studied and understood. These include multi-tiered architecture, server and client-side scripting techniques, implementation technologies, programming language (such as PHP, HTML, CSS, JavaScript) and MySQL relational databases. This is a project with the objective to develop a basic website where a consumer is provided with a shopping cart website and also to know about the technologies used to develop such a website.
This document will discuss each of the underlying technologies to create and implement an e- commerce website.

30. Pros Cons
Bigger system – more processing
power, higher bandwidth, spatial
locality
Hardware layout and data
temporal locality needs could lead
to latency increase and non-
uniformity of access
Almost little to none configuration
changes lead to faster turnaround
time
The workload’s bulk and scale
could render it to work only with
ageing systems
Scaling

49. WHAT IS AN OPENJDK PORT?
• Windows on Arm64 was a new platform for OpenJDK
• In-order to run Java applications on this new
platform, we need to get the Java Runtime
Environment (JRE) to work on it.
• A JDK is a superset of a JRE as it includes tools and
utilities for development and debugging
• In order to be able to develop in Java, we need to
get the JDK to work on the new platform

Jakub’s talk had cat photos and it was awesome and brought a smile to my face, so here I have my cats and dogs. I hope they bring smile to yours as well
So let’s start from the very beginning –
Functionality – what it does
Operation – how it does it – The ability of a software to execute and evolve
Functionality – what it does
Operation – how it does it – The ability of a software to execute and evolve
Functionality – what it does
Operation – how it does it – The ability of a software to execute and evolve
Say you’d like to buy a car or a truck – and you’d like to be able to tow a trailer – now that becomes a desired attribute for useability and enables scalability
In this talk, I’d like to walk a few of this attributes with you
Security – e.g. Transport Layer Security (TLS 1.3 vs 1.0)
Observability: ability to understand complex systems internal state based on workloads, e.g. JFR
and together we can investigate the What the How. First we will dive into designing a GC for performance, then we will look at Scalability and investigate VMs for either scale out or scale up purposes
let’s dive in deeper to performance requirements by trying to define the attributes first
so what’s the first thing that people talk about when discussing performance? Say if you ask your end user “what needs to happen inorder for our system to be performant?” what would their answer look like?
Let’s get some clarity on that
But make sure you define what fast means to your customer. Refine definition This is gathering details wrt nfr.
Footprint is the space that is needed to run your software.It's both about the memory footprint and also the physical resources
Responsiveness: If I send a stimulus now, how much time ’til I get a response back?
Throughput: How can I maximize the operations per second of my system?
Availability is the uptime and Mean Time Between Failure of the system
Let’s start with what we mean by response time.
If I send a stimulus now, how much time ’til I get a response back?
How can I maximize the operations per second of my system?
Work done is Throughput = operations per second. (transactional DB) transactions per second, (query DB): requests per second
Now that we know some of the attributes, let’s try to understand the how
Before we start with our GC architecture, let me give you a fact that will help clarify why I chose GC for the perf requirement exercise.
So, what do we know – we know that the GC will need to do some GC work and then we also know the weak generational hypothesis that most objects will die young.
No concurrency == app has max utilization of resources and that should give it good throughput
Regions == smaller work units. More granularity. All concurrent work needs maintenance barriers. With that we have successfully architected two GCs
Next ility
What’s the age-old question that everyone wants to know?
Now that we know some of the attributes, let’s try to understand what they stand for and then let’s dive in deeper to performance requirements by investigating the how
At 1, it looks like it could handle the number of concurrent users or requests to fit in with the other cores
At 2 and at 3, we see concurrency effects
Normalized =(C18-MIN(C18:C25))/(MAX(C18:C25)-MIN(C18:C25))
Single JVM for gen 3 performs just as well as dual JVM on Gen 2 – so basically Gen 2 will benefit from scale out and Gen 3 will benefit from scaling up to the max cores.
Gene Amdahl shows that there is a fraction of the workload which cannot be parallelized, called serial fraction i.e. no matter how many cores are allocated for the program, only a single core will be executing the serial portion of the program. We use σ to denote this serial fraction of workload. Hence (1-σ) becomes the parallel fraction of workload. σ takes values in the range (0, 1).
Continuous validity of single processor
Universal Scalability Law (USL) is an extension of Amdahl’s law. It accounts for the additional overhead due to interprocess communication that happens application software level, middleware level, operating system level, and hardware level.
Three Cs: Concurrency (gamma), Contention (alpha), Coherency (beta)
Universal Scalability Law (USL) is an extension of Amdahl’s law. It accounts for the additional overhead due to interprocess communication. Interprocess communication happens at multiple levels within the system: application software level, middleware level, operating system level, and hardware level.
J/ava is portable.
What does it mean for openjdk?
Executables(In the bin/ subdirectory) An implementation of the Java Runtime Environment (JRE). The JRE includes a Java Virtual Machine (JVM™), class libraries, and other files that support the execution of programs written in the Java programming language. This directory also includes tools and utilities that will help you develop, execute, debug, and document programs written in the Java programming language. For further information, see the tools documentation at https://docs.oracle.com/en/java/javase/12/tools/tools-and-command-reference.html
Configuration files(In the conf/ subdirectory) Files that contain user-configurable options. Files in this directory can be edited to change the JDK's access permissions, configure security algorithms, and set the Java Cryptography Extension Policy Files which might be used to limit the JDK's cryptographic strength.
C header Files(In the include/ subdirectory) C-language header files that support native-code programming with the Java Native Interface and the Java Virtual Machine (JVM) Debugger Interface.
Compiled Java Modules(in the jmods/ subdirectory) Compiled modules used by jlink to create custom runtimes.
Copyright and License files(in the legal/ subdirectory) License and copyright files for each module. Includes third party notices as .md (markdown)files.Additional Libraries(In the lib/ subdirectory) Additional class libraries and support files required by the JDK. These files are not intended for external use.
In the opening keynote we heard about project Amber and how removing the boiler plate is making the Java language much more usable. So let’s briefly look at Usability
Usability is user-friendliness be it about language level boiler plate removal or having GC with minimal to none command line options or if your error messages like nullpointerexceptions in JDK14
User Experience is perception and reaction to a feature – like some people may prefer Java 19 over
Kotlin due to the “User Experience”
Customer experience is about the total journey – you will have various touchpoints with your customer.
I have this awesome quote by Alan who is the head of SRE @JP Morgan
https://www.testingtime.com/en/blog/usability-ux-and-cx-compared/
'nfr' needs more love and appreciation from engineers and products. at the end of the day "customer experience = capability + reliability + security" - all are equally critical. a lot of manpower and brainpower are drained today due to support work and manual toils. to make a platform more reliable, those time/resources/power will be reinvested to innovation and creation...and better products.
As we say our goodbyes today, I’d like to leave you with a few thoughts -
Throughout this conference and this talk there was a theme of efficiency. So I’d like to say that Ilities are Qualities that make us efficient. So, I hope you internalize them.
They are asking you to be efficient.
Measure in all dimensions
Efficiency is defined as the ratio between speed up and the number of processors
E(p) = S(p)/P
Concurrency is one of those requirements that might as well be specified with f
Microsoft ported OpenJDK to Windows on Arm to support Azure servers, Minecraft, and other scenarios.
Minecraft coming soon to Windows on Arm devices.
LinkedIn hundreds of thousands of JVMs powering every feature of the service.
Bing: indexing services powered by OpenJDK. Bing is the search engine on Windows, behind “Search results” in the Start menu.
Minecraft Realms: Microsoft-hosted servers of Minecraft for world-wide community of Minecraft players.
Yammer: creators of Java frameworks like Dropwizard. Powers certain features behind Office 365/MS Teams.
Azure: infrastructure control plane leverages some Java-based services for resource provisioning orchestration.
Nuance and Metaswitch: Recent Microsoft acquisitions heavily invested in Java technologies
Let’s get some clarity on that
