This document discusses lessons learned from implementing microservices in production environments. It outlines both the benefits of microservices, such as scalability and fault tolerance, as well as challenges, including loose coupling, greenfield development, and culture. Specific lessons include containing failures, using caching and logging for fault tolerance, building contracts to enable loose coupling, starting with a monolith then extracting services, and ensuring an automated testing and deployment culture. The key takeaway is that microservices are difficult to implement and the challenges must outweigh the benefits for an organization.
Microservices: lessons from the trenchesMehdi Khalili
Microservices are awesome, when they're done right. Teams start with microservices with the best intentions and sometimes end up hurting themselves and the business in doing so. There are many gotchas and oversights that could make the experience a bit painful or in some cases a complete disaster. In this presentation I talk about some of the happy and not so happy lessons I've learnt in implementing microservices over the years.
Sildes of an internal talk given at Twitter similar to a previous webinar for Redhat with the same title.
Speeding up development is a key concern, cloud and technology improvements like Docker speed up key steps that make continuous delivery possible. Breaking up the work into many separate microservices and datastores with stable APIs allows teams to make progress independently so that the organization scales. Monolithic apps are preferred for small projects, built by small teams and when very low latency and high efficiency is the primary requirement. Monitoring microservices is currently a challenge with solutions starting to emerge.

Automated UI testing done right (DDDSydney)Mehdi Khalili
Many teams try Automated UI Testing and many fail. Automated UI Testing is hard: the tests take a lot of time to write and tend to be brittle and hard to maintain. In this session I will provide you with some practical advice on how to and how not to write your tests introducing you to some UI testing ideas, patterns and frameworks that will help you write your tests faster while making them less brittle and easier to maintain.
This is an action packed session for testing enthusiasts.
codecentric AG: CQRS and Event Sourcing Applications with CassandraDataStax Academy
CQRS (Command Query Responsibility Segregation) is a pattern, which separates the process of querying and updating data. As a query only returns data without any side effects, a command is designed to change data. CQRS is often combined with Event Sourcing. This is an architecture in which all changes to an application state are stored as a sequence of events.
Because of its great capability to store time series data Cassandra is the perfect fit for implementing the event store. But there a still a lot of open questions: What about the data modeling? What techniques will be used to process and store data in the Cassandra database? How to access the current state of the application, without replaying every event? And what about failure handling?
In this talk, I will give a brief introduction to CQRS and the Event Sourcing pattern and will then answer the questions above using a real life example of a data store for customer data.
Microservices are an essential enabler of agility but developing and deploying them is a challenge. In order for microservices to be loosely coupled,each service must have its own datastore. This makes it difficult to maintain data consistency across services.
Deploying microservices is also a complex problem since an application typically consists of 10s or 100s of services, written in a variety of languages and frameworks. In this presentation, you will learn how to solve these problems by using an event-driven architecture to maintain data consistency and by using Docker to simplify deployment.

From Monoliths to Services: Paying Your Technical DebtTechWell
Ever since distributed software became popular, developers have been choosing whether to use monolithic architectures or service-oriented architectures. With the advancement of cloud infrastructure and the widespread implementation of agile methodologies, the latter approach has been getting much easier. David Litvak describes how a monolithic application—due to its ever increasing technical debt—can become too big to support. He explores how to gradually reduce the size by extracting its components into smaller services, so ultimately the application is decoupled and highly distributed. David describes the current situation of cloud services and software as a service providers, offering a list of these providers for many different uses. He shares an example of an e-commerce site implementation, starting with a full-blown traditional rails monolith and then moving toward a static site with automated rebuilds with CircleCI, Contentful as a decoupled CMS, Auth0 for authentication, and Snipcart as an e-Commerce as a Service provider. Join David as he shares how to create an architecture from interconnected services.
The Cloud Foundry APIs provide a rich set of information for anyone trying to gain insight into the inner workings of the platform. This presentation explores some of the APIs, and provides some practical techniques for non-coder ways of interacting with those APIs.

Speaker: Chris Munns, Business Development Manager, DevOps at Amazon Web Services
Title: DevOps @ Amazon: Microservices, 2 Pizza Teams, & 50 Million Deploys a Year
Right on the heels of the Manifesto for Agile Software Development, a new movement with the moniker DevOps has further advanced software delivery. Although the Agile software development movement brought iterative and incremental concepts to our industry, in many organizations its reach was relegated to only the application development teams. In many cases, this moved the bottlenecks in organizations from application development to release management, IT operations and business program and portfolio management decision making. This local optimization leads to real world application of Agile software development being perceived as unsuccessful and increased probability of being thrown away for the comfort in the illusions of control of plan-driven approaches.
The promise of DevOps is to further improve our ability to make holistic optimizations from business to software delivery to operations and ultimately increase feedback into our business decision making processes. This promise involves the application of The Three Ways as described by Gene Kim: Flow, Feedback and Continuous Experimentation and Learning. Even for those that were able to take advantage of Agile software development we can not sit on our laurels. We must embrace continuous improvement in order to fend off the effects of “Software is Eating the World” as Marc Andreessen pronounced. DevOps provides a view on the culture, practices, tools and processes for how valuable software is delivered, operated and evolved to enable competitive advantage.

GDG Cloud Southlake #33: Boule & Rebala: Effective AppSec in SDLC using Deplo...James Anderson
Effective Application Security in Software Delivery lifecycle using Deployment Firewall and DBOM
The modern software delivery process (or the CI/CD process) includes many tools, distributed teams, open-source code, and cloud platforms. Constant focus on speed to release software to market, along with the traditional slow and manual security checks has caused gaps in continuous security as an important piece in the software supply chain. Today organizations feel more susceptible to external and internal cyber threats due to the vast attack surface in their applications supply chain and the lack of end-to-end governance and risk management.
The software team must secure its software delivery process to avoid vulnerability and security breaches. This needs to be achieved with existing tool chains and without extensive rework of the delivery processes. This talk will present strategies and techniques for providing visibility into the true risk of the existing vulnerabilities, preventing the introduction of security issues in the software, resolving vulnerabilities in production environments quickly, and capturing the deployment bill of materials (DBOM).
Speakers:
