Why Enterprises Are Embracing the Cloud
After being deeply involved in public cloud for the last several years, as both a provider and a consumer, I have been very pleasantly surprised at the rate at which large enterprises are rapidly moving to the cloud. For all the right reasons, even the most regulated and risk-averse of industries -- banking, for example -- are rapidly moving workloads out of their own owned data centers. Public cloud is not just for the "unicorns", but for the "horses" as well. This short vignette, presented at the GOTO Aarhus 2014 conference, tries to explain why this trend will continue and accelerate, and why we should be excited about it.
Optimizing Java Performance
This document discusses optimizing Java performance under high load conditions. It recommends measuring performance before and after changes rather than guessing. Some techniques discussed include caching data to reduce I/O, minimizing database operations, reducing memory allocations and garbage collection, and optimizing iteratively by measuring the impact of each change. The key ideas are to identify bottlenecks by measuring performance, consider ways to reduce unnecessary operations like I/O, and make optimizations in iterative cycles of measuring the impact of each change.

This document provides an overview of building your own machine learning platform. It discusses typical machine learning workflows and ecosystems, challenges such as diverse technologies and reproducible environments, and potential solutions like the Hadoop, Mesos, and Kubernetes ecosystems. It assesses criteria like cost and production needs. Finally, it provides examples of platforms and demos a recommender system implementation using tools like Spark, HDFS, HBase, and Python/Scala within a delivery pipeline.
ClojureScript: I can't believe this is JavaScript
There are 6 difficult problems frameworks and libraries try to solve in JavaScript, but never quite get there. Learn how these problems (and more!) are solved by ClojureScript and how it can provide a platform for new solutions.
Entity framework advanced
The document summarizes an Entity Framework session that covers topics like eager vs lazy loading, asynchronous queries and saves, optimistic concurrency, and best practices. The agenda includes loading related objects, non-blocking data access, handling concurrency issues, and techniques like avoiding singletons, updating versions, using stored procedures for complex queries, and caching expensive results. General recommendations are to limit result sets, embrace asynchronous patterns, and use fast serializers.

Building JavaScript Apps for Force.com with EmberJS
The document discusses using the EmberJS framework to build JavaScript apps for Force.com instead of Visualforce. EmberJS offers advantages like Handlebars templates that update automatically, scaffolding to reduce development time, friendly APIs, routing, and being open source. It compares how Visualforce works by rendering pages on the server with HTML, JavaScript, and Java while Ember apps work client-side with routing, data binding, and templating. The document also provides examples of how to integrate Ember apps with Force.com using Visualforce, JavaScript remoting, action functions, and Apex.
JavaScript & CSS Development Workflow
This document discusses workflows for JavaScript and CSS development in OutSystems. It notes that JavaScript and CSS changes often require many small tweaks, and publishing/republishing takes extra time. It recommends using browser debugging tools like the Styles, Computed, Console, and Sources tabs to understand CSS and JavaScript behavior without needing to republish. Additionally, it cautions developers to be aware of JavaScript and CSS loading order, avoid duplicating files, and keep common code in shared locations.

Threefold integration: CMS, TMS, and CAT — UTIC 2016
Dealing with a CMS as the source content repository can be quite cumbersome and challenging for a vendor, but the fact that it’s also an uncertain territory for customers creates a succulent business opportunity for those translation agents willing to invest and persevere in differentiating themselves through technology.
In this presentation, we will have a look at what it takes to build a workflow around your customer’s CMS and your existing tool ecosystem that (without breaking the bank) delivers the kind of efficiency and automation that, until recently, seemed only within the reach of the bigger players (and pockets) in our industry.

JFokus 2015 - Hacking the-monolith
Terrifying and fun both describe our head-on rapid transformation towards a microservice architecture. We will give you a live report from the trenches with our main choices, mistakes and takeaways concerning design principles, orchestration, ownership etc. SVT interactive is expanding rapidly which increases the complexity rapidly and increase the demands on modularisation. How do you at the same time keep a culture of freedom, experimentation and innovation.
Disassembling the Monolith: Taming Large Software Projects with Node.js
Software "Monoliths" are no longer in fashion. Everybody is extracting portions of their applications as "micro-services", and yet, few presentations cover exactly how to handle this.
Presented here are a few useful techniques for building distributed systems with Node.js.
Dismantling the Monolith: Scaling with Microservices
The document summarizes an internal tech talk on migrating from a monolithic architecture to microservices. It discusses:
1. The problems with monoliths including difficulty of change, testing, and scaling monoliths as complexity grows.
2. The microservices approach of developing applications as suites of small, independent services that communicate via APIs and can be developed and scaled independently.
3. An example of online retailer Gilt experiencing outages due to inability to scale their monolithic transaction processing module.
4. Recommendations for iteratively migrating to microservices by stopping monolith growth, rewriting features as services, using well-defined interfaces between loosely coupled services.
Monolith vs Microservices vs Teams
Talk about why monoliths are not supposed to be evil, how not to make them evil, how to know the right time for decoupling monolith into microservices.
Breaking the Monolith - Microservice Extraction at SoundCloud
This document summarizes SoundCloud's journey from a monolithic Rails application to a microservices architecture. It describes SoundCloud's initial architecture using Rails and MySQL. As traffic grew, they scaled vertically by adding caching, workers, and database optimizations. They eventually extracted services like messages into independent Scala/Finagle services for improved scalability, deployability and maintenance. The summary discusses the risks of integrating new services and retiring old components, highlighting the need for load testing, rollback plans, and handling stale clients during the migration.
Splitting the Monolith

Breaking the monolith at jobandtalent - AWS Summit Barcelona 2015
The document discusses how jobandtalent transitioned from a monolithic architecture to a microservices architecture to support their growth of 10 million users per month. They were facing challenges from technical debt, team contention, and slowing development as a monolith. By breaking into independent microservices running on AWS, they were able to scale their platform, teams, and product more easily through horizontal scaling and continuous delivery. Key AWS features like API Gateway, auto scaling, and Redshift helped provide coordination, cost control, and data aggregation across the independent services.
My Monolith is Melting - PIPELINE CONF 2015
Bringing change to legacy systems and monolithic waterfall programs is daunting, but doable. In this session we’ll look at a real world example of how we undertook the technical, cultural and process challenges to move to continuous delivery in a big organisation. You’ll hear about the epic battles with the dreaded CAB (Change Approval Board), the fight to move architecture discussions from Word documents to the whiteboards, and the myriad smaller skirmishes along the path to delivering features to our users faster, safer & more measurably.

Monolith to Microservices - O’Reilly Oscon
The document summarizes HomeDepot.com's transition from a monolithic architecture to microservices. It discusses how in 2011, the monolith had grown large and difficult to manage, with long release cycles. The objective was to increase the rate of change and number of developers. Key steps included breaking the monolith into domain-driven services, adopting continuous integration, using APIs for communication, and implementing feature flags and traffic routing. This allowed independent development of 30 apps by 2015 compared to just 1 previously, with weekly instead of monthly deployments. The presentation provides guidance on patterns for microservice communication, deployment, data management, and avoiding common pitfalls.
DPM UK: Stealing Project Management Lessons from Artificial Intelligence
This document discusses lessons that can be learned from artificial intelligence to improve project management. It covers three key topics: 1) autonomy and how enabling independent decision-making within a team towards a common goal leads to success, 2) how machines learn and how deliberate practice can help teams improve, and 3) the importance of re-creation and motivation through purpose, autonomy, mastery, and inclusion to help teams perform at their best. The key lessons are that autonomy, clear communication of goals, letting individuals define how goals are achieved, helping design work as deliberate practice, conducting regular retrospectives, and ensuring purpose, autonomy, mastery and inclusion will help teams succeed.
I-Tier: Breaking Up the Monolith @ Philly ETE
Groupon recently completed a year-long project to migrate its U.S. web traffic from a monolithic Ruby on Rails application to a new multi-application stack with substantial results.
Groupon’s entire U.S. web frontend had been a single Rails codebase from its inception in 2008. The frontend codebase quickly grew large, which made it difficult to maintain and challenging to ship new
features. As a solution to this gigantic monolith, we decided to re-architect the frontend by splitting it into small, independent and more manageable pieces. At the center of this project, we rebuilt each
major section of the website as an independent application. We also rebuilt the infrastructure to make all the independent apps work together. Interaction Tier (I-Tier) was the result.
Learn about how Groupon achieved this great architecture migration and the business results it is driving.

The document discusses how Rise Science, a young company focused on sleep improvement and user enjoyment, embraced a monolithic architecture to allow their small teams to iterate quickly without breaking things. It outlines some of the obstacles they faced with separate data silos and tooling, and how centralizing their data in a single database and using Django as their framework helped break down silos and enabled self-serve analytics to improve their data culture and product development cycles.
Surviving as a Monolith in a Microservices World - by Blair Olynyk, Hyperwallet
This document discusses how to succeed without adopting microservices when your application is currently a monolith. It recommends aligning your development teams and application architecture with your organization's structure to gain benefits similar to microservices. The organizational structure should be based on your domain model using domain-driven design. If your code is tangled, apply the "strangler pattern" to refactor it by wrapping the monolith in microservice facades over time. This approach helped Hyperwallet increase productivity by 34% without fully transitioning to microservices.

- Netflix evolved from a monolithic architecture to a microservices architecture due to bottlenecks from organizational growth and diverse functionality in the monolithic stack.
- Microservices address these issues by decomposing applications into independently deployable services but introduce new challenges around service discovery, communication between services, and failure handling.
- Netflix developed best practices for microservices including service discovery with Eureka, load balancing with Ribbon, failure mitigation with Hystrix, and reactive inter-process communication with RxJava and tools like Ribbon and Hystrix.
From the Monolith to Microservices - CraftConf 2015
Most large-scale web companies have evolved their system architecture from a monolithic application and monolithic database to a set of loosely coupled microservices. Using examples from Google, eBay, and other large-scale sites, this talk outlines the pros and cons of these different stages of evolution, and makes practical suggestions about when and how other organizations should consider migrating to microservices. It continues with some more advanced implications of a microservices architecture, including SLAs, cost-allocation, and vendor-customer relationships within the organization. It concludes by exploring a set of common service anti-patterns.
MicroserviceArchitecture in detail over Monolith.
This document discusses microservices architecture as an alternative to monolithic architecture. It defines microservices as independently deployable services that communicate through lightweight mechanisms like HTTP APIs. The document outlines benefits of microservices like independent scalability, easier upgrades, and improved developer productivity. It also discusses prerequisites for microservices like rapid provisioning, monitoring, and continuous deployment. Examples of microservices frameworks and a demo application using Spring Boot are provided.
Pragmatic Microservices
One of the most powerful trends in software today is building large systems out of composable microservices. Many large-scale web companies have migrated over time to this architecture – and for good reason. But, as with any powerful technique, microservices come with their own brand of tradeoffs, and it is important to be aware of them before deciding whether they are appropriate in any particular case. They are not for every scale of problem, for every stage of company, or for every team.
This session takes a pragmatic approach to microservices, and compares them to the alternatives at different stages of company evolution. Using examples both from Google and eBay as well as from smaller organizations, it makes practical suggestions about whether, when, and how an organization should consider adopting a microservices architecture. Assuming microservices are the appropriate choice, it outlines an experience-based, incremental approach to making a successful rearchitecture to microservices.
The Journey from Monolith to Microservices: a Guided Adventure
SpringOne Platform 2016
Speaker: Mike Gehard; Senior Software Engineer, Pivotal
Are you starting a new application and wondering whether to go with a monolith or take the microservices path? Do you have an existing application that is getting too big to deliver business value with a predictable velocity? Ever wonder how to regain the agility you had when an application was smaller?
The current discussions around application architecture with microservices seem like an all or nothing journey without any stops along the way to catch your breath. This talk outlines questions to ask yourself to drive decisions along the way. It also demonstrates one possible path for future growth, complete with intermediate stops along the way where you can pause to evaluate your next step. This path avoids implementing too much complexity early in the process.
At the end of the journey you will not only have ideas to guide your own path, but tools that you can use to make the journey easier and less costly.

MassTLC Cloud Summit Keynote
Netflix has evolved to rely heavily on cloud infrastructure from AWS. It uses microservices across multiple availability zones to provide highly available and scalable streaming globally. Netflix has open sourced many of the tools it has developed to operate in the cloud under the NetflixOSS project. It continues to migrate more systems like billing, payments, and big data analytics to the cloud.
Microservices Design and Best Practices on AWS
Businesses are turning to microservices to help them enable their autonomous teams, letting them innovate and release solutions faster than ever before.
Implementing a microservices architecture has new challenges that need to be dealt with. Top amongst them is finding a platform to help manage a growing number of independently deployable services and use that platform efficiently.
This session will provide an overview of the benefits and challenges of microservices, and share best practices for architecting and deploying microservices on AWS. The session will look at different approaches you can take to run microservices applications at scale and explore how services like Amazon ECS, AWS Lambda ,etc.
Objectives:
1. Understand the fundamentals of the microservices architectural approach
2. Learn best practices for designing microservices on AWS

Microservices Gone Wrong!
With popular poster children such as Netflix and Amazon, using microservices-based architectures seems to be the killer approach to twenty-first-century architecture. This session goes over the benefits, but more so the pitfalls, of using a microservices-based architecture. What impact does it have on your organization, your applications, and dealing with scale and failures, and how do you prevent your landscape from becoming an unmaintainable nightmare?
Expecto Performa! The Magic and Reality of Performance Tuning
In the enterprise there are rarely simple solutions to highly nuanced problems that satisfy all needs. Several customers might each ask "How do I make Jira/Confluence faster?" and each require a different answer. Using this example, this talk will pick apart the inputs, outputs, concerns, and realities of answering a short question with a long answer. We'll then discuss real-world examples from our own internal instances, to give you a taste of the process we've gone through to solve our own performance problems, and to show why there is no simple playbook; "it depends" on a lot! The key takeaways are:
* The importance of having a shared definition of performance
* The importance of having agreed-upon priorities, including what isn't important
* The importance of measuring (allthethings) and understanding them
* The thing you think is the problem might not be the problem, and vice versa.
* The real world and the ideal world tend to look nothing alike!

Tech Talk on Cloud Computing
The document discusses 3 key ways that developing software for the cloud differs from traditional approaches:
1. Incremental delivery, with frequent small releases of new features rather than large periodic releases.
2. Increased automation, including automated testing and continuous integration/deployment pipelines to support more agile development and deployment.
3. Analytics of usage data to inform product decisions and ensure features are valuable to users. Developing with the cloud in mind requires rethinking processes to focus on agility, automation and data-driven insights.

Measures in SQL (SIGMOD 2024, Santiago, Chile)
SQL has attained widespread adoption, but Business Intelligence tools still use their own higher level languages based upon a multidimensional paradigm. Composable calculations are what is missing from SQL, and we propose a new kind of column, called a measure, that attaches a calculation to a table. Like regular tables, tables with measures are composable and closed when used in queries.
SQL-with-measures has the power, conciseness and reusability of multidimensional languages but retains SQL semantics. Measure invocations can be expanded in place to simple, clear SQL.
To define the evaluation semantics for measures, we introduce context-sensitive expressions (a way to evaluate multidimensional expressions that is consistent with existing SQL semantics), a concept called evaluation context, and several operations for setting and modifying the evaluation context.

- 20. Tips
- 21. Manage your service explosion • If possible use REST JSON • Don’t create a service per idea • Infrastructure • Monitoring • Client gems/libraries • Have configuration conventions
- 23. Large data • Think millions of rows • Forget JSON • CSV is your friend
- 24. Use docker • At least to run tests • Eliminates ‘works on my machine’
- 25. Automate build/deployment • Use service (codeship, travis, snapci) • Roll your own (jenkins)
- 26. Should I do it? • You need to be big enough • DO NOT start out this way
