Heroku
Heroku is a platform as a service that originally started as a Ruby PaaS but now supports Node.js, Clojure, Grails, Scala, and Python. It uses the Git version control system for deployment and a dyno process model for scaling applications. While flexible in allowing custom buildpacks and configuration via environment variables, there are also restrictions like maximum source code size and memory limits for dyno processes.
Legacy Sins
Eberhard Wolff discusses several factors that contribute to creating changeable software beyond just architecture. He emphasizes that automated testing, following a test pyramid approach, continuous delivery practices like automated deployment, and understanding the customer's priorities are all important. While architecture is a factor, there are no universal rules and the architect's job is to understand each project's unique needs.
Micro Services - Small is Beautiful

High Availability and Scalability: Too Expensive! Architectures for Future E...
The document discusses high availability and scalability approaches for enterprise systems. Traditionally, enterprises rely on highly reliable hardware, small clusters, and standby data centers. However, this approach is expensive and systems can still fail. The document proposes using virtualization, stateless servers, and NoSQL databases to achieve high availability and scalability at lower cost. Servers are provisioned as "Phoenix servers" that can be easily recreated if failed, without relying on expensive reliable hardware. Data is distributed across servers for redundancy and fine-grained scaling. This software-based approach provides better performance and availability compared to traditional hardware-centric methods.
Java Application Servers Are Dead!
This document discusses the declining relevance of traditional Java application servers. It argues that application servers are no longer needed as containers for multiple applications due to limitations in isolation. Modern applications are better suited as individual JAR files with their own custom infrastructure and standard monitoring and deployment tools rather than relying on application server-specific approaches. Frameworks like Spring Boot and Dropwizard provide an alternative to application servers by allowing applications to be self-contained deployable units without dependency on external application server infrastructure.
Micro Service – The New Architecture Paradigm
The document discusses microservices as a new software architecture paradigm. It defines microservices as small, independent processes that work together to form an application. The key benefits of microservices are that they allow for easier, faster deployment of features since each service is its own deployment unit and teams can deploy independently without integration. However, the document also notes challenges of microservices such as increased communication overhead, difficulty of code reuse across services, and managing dependencies between many different services. It concludes that microservices are best for projects where time to market is important and continuous delivery is a priority.
Continuous Delivery and Micro Services - A Symbiosis
Continuous Delivery profits from Micro Services - and the other way round. This presentation shows how the two technologies work together - and how Micro Services can be used to simplify the transition to Continuous Delivery.
IaC? VSTS to the rescue! Abbreviations explained

Developing Microservices using Spring - Beginner's Guide
This document provides an overview of microservices and how to develop them using Spring. It discusses the challenges of distributed systems and how Spring Boot and Spring Cloud Netflix address areas like configuration, service registration, load balancing, fault tolerance, and monitoring. Examples are provided for building microservices with Spring Boot, integrating configuration with Spring Cloud Config, registering services with Eureka, load balancing with Ribbon and Feign, handling faults with Hystrix, and monitoring with Hystrix Dashboard. Reactive programming with RxJava is also introduced as an approach for concurrent API integration.
Developing Resilient Cloud Native Apps with Spring Cloud
Distributed and massively scalable systems are difficult to design, implement, and operate. Further, microservice architectures are supposed to enable your business to be disruptive and innovative. Thankfully, two communities have emerged to facilitate easier solutions for these concerns and do a lot of the work for you: Spring Cloud OSS and Cloud Foundry. In this talk, we will take a deeper look at preventing cascading failures using Hystrix, as well as illustrate a mechanism for A/B testing using Eureka and blue-green deployments on Cloud Foundry.
Microservice - All is Small, All is Well?
This document discusses microservices and their advantages and disadvantages. Microservices are small, independent units that work together to form an application. They allow for independent deployment and use of different technologies. While this improves scalability and agility, it also introduces challenges around distributed systems, refactoring code between services, and operating at scale. The key is to start with a functional architecture and limit communication between services.
Backing Data Silo Atack: Alfresco sharding, SOLR for non-flat objects
The document discusses a scheme for sharding Alfresco repositories to address scalability and storage limitations. Key points of the scheme include:
- Repositories are sharded across multiple independent servers, each storing a part of the content.
- A level 7 switch balances requests across repositories and provides a single API entry point.
- An external SOLR cloud indexes all repositories in a single index to allow federated queries.
- The scheme is benchmarked to scale to 15,000 concurrent users on commodity hardware. Additional considerations for production include auto-discovery, configuration management, and safety checks.

You don’t need DTAP + Backbase implementation - Amsterdam 17-12-2015
DTAP is already an outdated concept in 2016. Instead an idea of immutable infrastructure should be used. Backbase in partnership with Levi9 have employed the concept of immutable infrastructure to revolutionize the way Custemer Experience Platform (CXP) is developed and released.
"Framework Principal" pattern
This document discusses the "Framework Principal" pattern which allows optimizing resource usage across multiple applications by initializing shared services and configurations in a single starter class. The Framework Principal runs very early and can be used to launch services independently of any application based on configuration properties. It provides examples of how to configure different applications to use the same Framework Principal by specifying different property files and user names for production vs sandbox environments. This allows launching shared services only once across multiple applications rather than separately in each one.

2) A REST API and UI allow users to easily provision new environments from available server stacks configured with Ansible for testing.
3) This enables Backbase to implement continuous delivery practices like automated testing of new versions without affecting production environments.
Future of Java
This document discusses the future of Java and its key components: the Java Virtual Machine (JVM), the Java language, and the Java Community Process (JCP) standards. It notes that while the JVM is widely used and will remain important, the Java language has seen little innovation compared to other languages and the standards process has produced some poor specifications. However, Java still dominates the market due to its large existing base and the persistence of the JVM. The future of Java is uncertain but the JVM and open source development may help ensure its continued relevance.
Avoiding integration hell
The document discusses integration hell, which can occur when developing software if changes and deployments happen too frequently without proper processes. It provides details on a real-world project with 6 developers, over 900 files, and a deployment every 43 minutes on average. Recommendations are made around using tools like Git, Jenkins, virtualenv, and others to help manage the integration process and spot problems early.
CI/CD and Asset Serving for Single Page Apps
This document discusses modern CI/CD and asset serving practices. It defines continuous integration as running automated tests on code changes to provide quick feedback. Continuous deployment automates releasing code to production without human intervention. The document recommends keeping the CI/CD pipeline fast through practices like modular code and fast tests. It also discusses asset serving techniques like versioning assets, maintaining canary environments, and notifying users of new releases. Overall, the document promotes CI/CD and advanced asset serving practices to increase velocity, reliability and user experience for modern web applications.
Setting Up CircleCI Workflows for Your Salesforce Apps
This document discusses setting up CircleCI workflows for Salesforce apps.

It demonstrates configuring and running the workflow in CircleCI and adding a quality gate using static code analysis with Apex PMD. Next steps discussed include breaking projects into smaller packages and parallelizing tests.
Immutable infrastructure with Boxfuse
We often employ the "build-once-run-everywhere" principle to our application binaries. Our build server builds an artifact and puts it in a repository, this same artifact is then promoted from environment to environment, from test to production, to make sure that what ends up in production is the very same thing as what we have thoroughly tested before.
Now, in a world of virtualization, what if we were to do the same thing with our complete infrastructure? In stead of just building our application and promote it from environment to environment, what if we would build a complete virtual machine image and do the same with that? Could we?
This is what immutable infrastructure is about. Boxfuse can help you get there.
Java Application Servers Are Dead! - Short Version
The document discusses issues with traditional Java application servers and argues that they are outdated for modern applications. It notes that application servers do not fully isolate applications, that dependencies on specific application server versions and libraries hinder portability, and that their deployment and monitoring tools do not integrate well with standard operating system tools. It suggests that modern applications would be better served by packaging all dependencies into executable JAR files and providing their own lightweight infrastructure instead of relying on application servers.

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.

Odoo ERP Vs. Traditional ERP Systems – A Comparative Analysis
When it is all about ERP solutions, companies typically meet their needs with common ERP solutions like SAP, Oracle, and Microsoft Dynamics. These big players have demonstrated that ERP systems can be either simple or highly comprehensive. This remains true today, but there are new factors to consider, including a promising new contender in the market that’s Odoo. This blog compares Odoo ERP with traditional ERP systems and explains why many companies now see Odoo ERP as the best choice.
What are ERP Systems?
An ERP, or Enterprise Resource Planning, system provides your company with valuable information to help you make better decisions and boost your ROI. You should choose an ERP system based on your company’s specific needs. For instance, if you run a manufacturing or retail business, you will need an ERP system that efficiently manages inventory. A consulting firm, on the other hand, would benefit from an ERP system that enhances daily operations. Similarly, eCommerce stores would select an ERP system tailored to their needs.
Because different businesses have different requirements, ERP system functionalities can vary. Among the various ERP systems available, Odoo ERP is considered one of the best in the ERp market with more than 12 million global users today.
Odoo is an open-source ERP system initially designed for small to medium-sized businesses but now suitable for a wide range of companies. Odoo offers a scalable and configurable point-of-sale management solution and allows you to create customised modules for specific industries. Odoo is gaining more popularity because it is built in a way that allows easy customisation, has a user-friendly interface, and is affordable. Here, you will cover the main differences and get to know why Odoo is gaining attention despite the many other ERP systems available in the market.

Microservice Teams - How the cloud changes the way we work
A lot of technical challenges and complexity come with building a cloud-native and distributed architecture. The way we develop backend software has fundamentally changed in the last ten years. Managing a microservices architecture demands a lot of us to ensure observability and operational resiliency. But did you also change the way you run your development teams?
Sven will talk about Atlassian’s journey from a monolith to a multi-tenanted architecture and how it affected the way the engineering teams work. You will learn how we shifted to service ownership, moved to more autonomous teams (and its challenges), and established platform and enablement teams.
Need for Speed: Removing speed bumps from your Symfony projects ⚡️
No one wants their application to drag like a car stuck in the slow lane! Yet it’s all too common to encounter bumpy, pothole-filled solutions that slow the speed of any application. Symfony apps are not an exception.
In this talk, I will take you for a spin around the performance racetrack. We’ll explore common pitfalls - those hidden potholes on your application that can cause unexpected slowdowns. Learn how to spot these performance bumps early, and more importantly, how to navigate around them to keep your application running at top speed.
We will focus in particular on tuning your engine at the application level, making the right adjustments to ensure that your system responds like a well-oiled, high-performance race car.

Graspan: A Big Data System for Big Code Analysis
We built a disk-based parallel graph system, Graspan, that uses a novel edge-pair centric computation model to compute dynamic transitive closures on very large program graphs.
We implement context-sensitive pointer/alias and dataflow analyses on Graspan. An evaluation of these analyses on large codebases such as Linux shows that their Graspan implementations scale to millions of lines of code and are much simpler than their original implementations.
These analyses were used to augment the existing checkers; these augmented checkers found 132 new NULL pointer bugs and 1308 unnecessary NULL tests in Linux 4.4.0-rc5, PostgreSQL 8.3.9, and Apache httpd 2.2.18.
