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.
Agile Engineering Traceability
The document discusses agile engineering and federated application lifecycle management (ALM). It defines agile practices like Scrum, Lean, XP and Kanban. It also discusses challenges with agility like testing overhead and keeping up with emerging technologies. Federated ALM is defined as integrating metadata, workflows and processes across development stages with customizable application development and integration flows.
Atagg2015 Benefits of BDD in Digital Era
The document discusses the benefits of behavior driven development (BDD) in the digital era. It introduces BDD and explains how it uses user stories written in Given-When-Then format to describe features from the user perspective. Key benefits of BDD include ensuring all development work maps to business objectives, satisfying user needs, efficient prioritization of features, and shared understanding across teams. The document also provides an example of a BDD framework architecture and demos applying BDD for testing human-machine interface applications.

Iasa Architect responsibilities in the cloud
Cloud platforms drive marketing campaigns that offer to simplify the hardest challenges of information technology. From resilience to scalability, disaster recovery to management, the cloud platforms offer to take the challenge off of the table forever! It can be easy to ?buy in? to the platform. Too often, we find out later that our responsibility as architects cannot ?end at the door? to the provider, that there are provisos and implementation considerations we discover ? often after the provider falls down.

Getting Started with Architecture Decision Records
Documenting architecture design decisions is commonly considered a good practice and yet many teams don't take the time to write down the decisions they make. In our experience this happens for a few reasons: documentation is rejected as being too heavyweight, documentation has little influence since it is typically out of sight and out of mind, and many developers don’t know what to document. Architecture Decision Records (ADRs) address many of these problems by capturing design decisions in a simple, lightweight templates that is stored close to repositories used by stakeholders -- often in the same repository as code affected by the ADR.
In this hands-on workshop you will learn how to write effective ADRs and how to overcome road bumps teams often experience when first getting started with ADRs. By the end of this session you will have the skills you need to champion ADRs and help your team start (or improve) your design decision log.

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.
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.
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.
Codemash 2007 - Scm with subversion
This document provides an overview of Source Code Management with Subversion. It discusses Subversion's history and features, including its support for directories, files, atomic commits, branching and tagging. It also covers enterprise considerations, the Subversion architecture with servers and clients, development processes using branches and merges, and tools for reporting. The presentation concludes with resources for support, training and learning more about Subversion.
Final_Presentation
This document discusses building scalable architectures using microservices. It begins by describing the traditional monolithic application architecture and its limitations around scalability. It then discusses how applications can be decomposed into independent services along functional and data boundaries to improve scalability. The key characteristics of microservices like independence, smaller size and improved deployability are explained. An example taxi booking application is used to illustrate how it could be decomposed into microservices for different functions like passenger management, driver management etc. Finally, some potential drawbacks of microservices like increased complexity of development, testing and operation are acknowledged.
Gilt from monolith ruby app to microservice scala service architecture
This document summarizes Yoni Goldberg's talk on Gilt's transition from a monolithic Ruby on Rails application to a distributed system of over 450 Scala microservices. Some of the key challenges they faced included scaling issues as traffic grew, difficulties deploying and testing changes across many interdependent services, and a lack of clear ownership over parts of the codebase. Gilt addressed these by moving to the JVM, embracing microservice architecture, using Docker for development environments, implementing automated testing and deployment tools, and emphasizing clear ownership of individual services.

An introduction to Microservices
This document provides an introduction to microservices architecture. It discusses why companies adopt the microservices style, how to design microservices, common patterns, and examples from Netflix.
The key points are:
1) Microservices architecture breaks applications into small, independent services that communicate over well-defined interfaces. This improves modularity, scalability, and allows independent deployments.
2) When designing microservices, services should be organized around business capabilities, have decentralized governance and data, and be designed to fail independently through patterns like circuit breakers.
3) Netflix is a leader in microservices and has open sourced many tools like Hystrix for latency handling and Eureka for service discovery that
Lean Software Development

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.
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.

How do you at the same time keep a culture of freedom, experimentation and innovation.
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.
Microservice Architecture
The document discusses microservices architecture. It defines microservices as an approach to developing a single application as a suite of small services that communicate with each other via lightweight mechanisms like HTTP APIs. Each service runs independently, is built around business capabilities, and can be deployed independently. There is minimal centralized management of services, which can use different programming languages and data storage technologies.

The agile elephant in the room
The document discusses two types of "Agile elephants" - hiding elephants which provide little information and fighting elephants which provide contradictory information. It focuses on how to handle non-functional requirements (NFRs) and technical stories, which are often elephants in Agile projects. It recommends tracking NFRs in acceptance criteria, backlogs, definitions of done, or separate specifications. Technical stories should not be treated as user stories, and the document discusses debates around including them in velocity estimates. It also provides techniques for estimating entire projects by decomposing epics and features into user stories.
How to Overcome Data Challenges When Refactoring Monoliths to Microservices
This document discusses strategies for refactoring monolithic applications into microservices when migrating from a relational database to a NoSQL database. It describes splitting the monolith by fracturing modules into encapsulated services. Alternatively, it proposes strangling the monolith by gradually creating new services around the edges of the existing monolith. When migrating data, it also discusses moving from shared database tables to independent data ownership between services. The document advocates for independent release cycles and a share-nothing architecture between loosely coupled microservices.
User Centered Agile Development at NASA - One Groups Path to Better Software
The group at NASA iteratively adopted agile practices over two years to improve their software development process. They started with six month development cycles and shortened this to six weeks and then three weeks. This allowed for more frequent customer feedback and prioritization of work. Daily builds and testing ensured progress was always visible. Their measure of success became working code delivered in frequent iterations rather than presentations or documentation.

Sgin2013 scrum accomplished-industrialagilecasestudy-avinashrao
The document discusses challenges with implementing Agile practices at scale within large enterprises. Some key points:
- Rework is higher in Agile projects which impacts perceived progress when measured by delivered size. However, Agile allows for earlier delivery of value.
- Large enterprises have additional pressures like non-Agile dependencies, approvals from various stakeholders, and contractual obligations that can reduce Agile team autonomy.
- Defining and splitting up requirements into user stories or features that multiple teams can work on simultaneously is challenging at scale. Approaches like hybrid WaterScrumFall may be needed.
- Showcasing progress, value delivered, and managing expectations is important when non-traditional measures don't align
