Microservices are small, autonomous services that work together to form an application. The document discusses the benefits of microservices as well as the "Seven Deadly Sins" that can plague microservices architectures: lust, gluttony, greed, sloth, wrath, envy, and pride. It provides examples and recommendations to avoid these anti-patterns, such as implementing circuit breakers, proper service boundaries, independent deployments, versioned APIs, and thorough automated testing.

With the rise of Docker, we have seen an unprecedented interest in container technologies where small companies and big enterprises bet their future on these technologies. This trend bases on an immense adoption of containers from software developers. And it has been agreed upon that they are considered highly beneficial for modern engineering practices like Agile and DevOps. But there is a new kid in town that proclaims a more radical approach: Serverless or FaaS: Function-As-A-Service. This paradigm suggests that a developer should only write functions and react to events.
The functions are written in high-level programming languages like Javascript, Java or Python, and the underlying compute infrastructure like containers or VMs is transparent to the user. That raises the question: Is the container revolution already dead before it really started? And who now needs container technologies in a serverless world?
In this talk we discuss these questions from both a containers advocate and serverless fanboy viewpoints. We confront these two approaches, show the differences, individual strengths and weaknesses and where they complement each other. This talk will also discuss motivations from different involved parties so that the audience can build their conclusion.

Azure cloud for the web frontend developersMaxim Salnikov
It’s impossible to reason about modern web application without mentioning its front-end part – extensive, feature-rich, performant, sometimes with quite sophisticated structure and build process, but after all not requiring server-side code to construct it in the runtime, i.e. static. In the Azure cloud, we now have a special service for this kind of apps (including both classic SPAs and statically generated ones), empowering developers to focus on the business logic rather than the infrastructure that builds and hosts them.
In my technical session & demo, let's go through the full development flow: we scaffold a web front-end app, push it to the GitHub, set up Azure Static Web App service, enjoy the fully automatic build, and deploy to global high-availability hosting - all in a few minutes!

API310 - How to refactor a monolith to serverless in 8 stepsYan Cui
Refactoring a monolith to serverless can be intimidating, but there are discrete steps that you can take to simplify the process. In this chalk talk, we outline eight steps for successfully refactoring your monolith and highlight key decision points such as language and tooling choices. Through real-world examples of successful migrations, we uncover common mistakes, useful techniques for identifying components for migration and service boundaries, and processes for migrating large amounts of data without downtime. Bring your refactoring challenges to this interactive session to see how these techniques can be applied in the context of your own application.
This is a small introduction to microservices. you can find the differences between microservices and monolithic applications. You will find the pros and cons of microservices. you will also find the challenges (Business/ technical) that you may face while implementing microservices.
From Zero to Serverless (CoderCruise 2018)Chad Green
So many times our customers need a simple routine that can be executed on a routine basis but the solution doesn’t need to be an elaborate solution without going the trouble of setting servers and other infrastructure. Serverless computer is the abstraction of servers, infrastructure, and operating systems and make getting solutions to your customer’s needs much quicker and cheaper. During this session we will look at how Azure Functions will enable you to run code on-demand without having to explicitly provision or manage infrastructure.
Jeremy Edberg (MinOps ) - How to build a solid infrastructure for a startup t...Startupfest
You're building your startup and you know it will be big. You don't want to spend a lot of time on infrastructure, but you also don't want to be putting out fires after you get mentioned on Hacker News. In this session, we will give you real practical tips that you can take home with you on building an infrastructure that will scale quickly with minimal up front work on your part, using time tested techniques in infrastructure as code, SaaS, and Serverless, among other things.
The microservice architectural style is an approach to developing a single application as a suite of small services, each running in its own process and communicating with lightweight mechanisms, often an HTTP resource API.
In this slide we have discussed, Monolithic application vs Microservices, applicable scenarios for adopting the architectural pattern, when we need microservices, what are the benefits, case study of an e-commerce platform by compartmentalizing the scopes into different sample microservices and Docker implementations.

Tokyo Azure Meetup #5 - Microservices and Azure Service FabricTokyo Azure Meetup
Azure Service Fabric is now Generally Available!
In this meetup we will start from the beginning and define what is microservice.
Next we will have a deep dive in Azure Service Fabric. Azure Service Fabric is one of the most interesting Azure service. Used internally in Microsoft for 5 years and backing up one of the most demanding Azure services today such as Azure SQL, Document DB, Cortana and Skype for Business.
We will be talking about the two models that are supported by Azure Service Fabric:
- Reliable Services (We will explore the reasons for having both stateful and stateless offerings in this model)
- Reliable Actors
Then we will talk how you can create Azure Service Fabric cluster on premise or in another cloud.
We will demo deployments in Azure for the various models.
Azure Service Fabric is the most advanced and complete offering for developing and hosting microservices in Azure. It builds on years experience Microsoft acquired running one of the most demanding services such as Azure SQL. Moreover, Azure Service Fabric solves very difficult distributed computing problems such as data synchronization, zero downtime deployment, update and rollback operations at large scale.
Join us to learn more about Azure Service Fabric and start using it immediately after the meetup!
For enterprises trying to stay ahead of the game, having a robust and fast application development program can make or break their market presence. The challenge for developers, however, is to build responsive, devise-agnostic applications in days, not months.
The Overview of Microservices ArchitectureParia Heidari
After reading, you are able to answer the following questions.
Why migrating to Microservices?
What are the advantages and drawbacks of Monolithic Architecture?
What are the advantages and disadvantages of Microservices Architecture?
What is the process of messaging in Microservices?
What is the process of integrating microservices with Pub/Sub?
DEVNET-1142 Decomposing Monolithic Applications to MicroservicesCisco DevNet
Microservices style architectures provide several benefits, such as enabling shorter delivery cycles, improved elasticity and resiliency. However, most existing applications are not developed using a microservices-style architecture. In this session, we describe how you can incrementally transform a traditional 3-tier monolith application, into a microservices style application. Beyond design and development of microservices, the session will also provide best practices and guidelines on the operations and cultural changes required for a successful transformation to Microservices.
The proliferation of good metrics collection and visualization toolkits over the past five years has been a huge benefit to developers. But with so many metrics available, along with a massive proliferation of services and limited cognitive capacity, which ones should we focus on?

Rise of the Machines - AI in the Agile WorldAidan Casey
Slides from my talk at aginext 2019.
In this session we’ll examine the AI capabilities available today in simple layman’s terms and explore how these will be used to augment and shape the agile world of tomorrow.
Artificial Intelligence (AI) has catapulted us into a brave new world of self-driving cars, delivery drones and talking robots. A combination of AI technologies including advanced machine learning, deep learning and natural language processing are now set to change the way we build and deliver products enabling us to build smarter software faster.
Imagine a world where product backlog prioritisation and feature discovery are aided by unbiased data analytics from AI systems. Self-learning products and adaptive user interfaces will automatically respond and adapt based on data driven analysis of real time user behaviour. Trouble shooting and recovery from production outages is accelerated and assisted by AI operations bots. This convergence of AI systems with the agile world will offer teams unprecedented visibility into their work and their products.
Globus Compute wth IRI Workflows - GlobusWorld 2024Globus
As part of the DOE Integrated Research Infrastructure (IRI) program, NERSC at Lawrence Berkeley National Lab and ALCF at Argonne National Lab are working closely with General Atomics on accelerating the computing requirements of the DIII-D experiment. As part of the work the team is investigating ways to speedup the time to solution for many different parts of the DIII-D workflow including how they run jobs on HPC systems. One of these routes is looking at Globus Compute as a way to replace the current method for managing tasks and we describe a brief proof of concept showing how Globus Compute could help to schedule jobs and be a tool to connect compute at different facilities.
Understanding Globus Data Transfers with NetSageGlobus
NetSage is an open privacy-aware network measurement, analysis, and visualization service designed to help end-users visualize and reason about large data transfers. NetSage traditionally has used a combination of passive measurements, including SNMP and flow data, as well as active measurements, mainly perfSONAR, to provide longitudinal network performance data visualization. It has been deployed by dozens of networks world wide, and is supported domestically by the Engagement and Performance Operations Center (EPOC), NSF #2328479. We have recently expanded the NetSage data sources to include logs for Globus data transfers, following the same privacy-preserving approach as for Flow data. Using the logs for the Texas Advanced Computing Center (TACC) as an example, this talk will walk through several different example use cases that NetSage can answer, including: Who is using Globus to share data with my institution, and what kind of performance are they able to achieve? How many transfers has Globus supported for us? Which sites are we sharing the most data with, and how is that changing over time? How is my site using Globus to move data internally, and what kind of performance do we see for those transfers? What percentage of data transfers at my institution used Globus, and how did the overall data transfer performance compare to the Globus users?
How to Position Your Globus Data Portal for Success Ten Good PracticesGlobus
Science gateways allow science and engineering communities to access shared data, software, computing services, and instruments. Science gateways have gained a lot of traction in the last twenty years, as evidenced by projects such as the Science Gateways Community Institute (SGCI) and the Center of Excellence on Science Gateways (SGX3) in the US, The Australian Research Data Commons (ARDC) and its platforms in Australia, and the projects around Virtual Research Environments in Europe. A few mature frameworks have evolved with their different strengths and foci and have been taken up by a larger community such as the Globus Data Portal, Hubzero, Tapis, and Galaxy. However, even when gateways are built on successful frameworks, they continue to face the challenges of ongoing maintenance costs and how to meet the ever-expanding needs of the community they serve with enhanced features. It is not uncommon that gateways with compelling use cases are nonetheless unable to get past the prototype phase and become a full production service, or if they do, they don't survive more than a couple of years. While there is no guaranteed pathway to success, it seems likely that for any gateway there is a need for a strong community and/or solid funding streams to create and sustain its success. With over twenty years of examples to draw from, this presentation goes into detail for ten factors common to successful and enduring gateways that effectively serve as best practices for any new or developing gateway.

Enhancing Research Orchestration Capabilities at ORNL.pdfGlobus
Cross-facility research orchestration comes with ever-changing constraints regarding the availability and suitability of various compute and data resources. In short, a flexible data and processing fabric is needed to enable the dynamic redirection of data and compute tasks throughout the lifecycle of an experiment. In this talk, we illustrate how we easily leveraged Globus services to instrument the ACE research testbed at the Oak Ridge Leadership Computing Facility with flexible data and task orchestration capabilities.
In software engineering, the right architecture is essential for robust, scalable platforms. Wix has undergone a pivotal shift from event sourcing to a CRUD-based model for its microservices. This talk will chart the course of this pivotal journey.
Event sourcing, which records state changes as immutable events, provided robust auditing and "time travel" debugging for Wix Stores' microservices. Despite its benefits, the complexity it introduced in state management slowed development. Wix responded by adopting a simpler, unified CRUD model. This talk will explore the challenges of event sourcing and the advantages of Wix's new "CRUD on steroids" approach, which streamlines API integration and domain event management while preserving data integrity and system resilience.
Participants will gain valuable insights into Wix's strategies for ensuring atomicity in database updates and event production, as well as caching, materialization, and performance optimization techniques within a distributed system.
Join us to discover how Wix has mastered the art of balancing simplicity and extensibility, and learn how the re-adoption of the modest CRUD has turbocharged their development velocity, resilience, and scalability in a high-growth environment.

• Best part is you end up with a standalone CI pipeline for each service but
within this pipeline we get to verify all expectations of the consumers of the
service !
• Gives consumers a safety net - their tests are continually run as part of the
API providers CI pipeline
• Pact broker - gives a picture of all the API consumers & the API call graphs
29. E2E User Journey Tests
• pick a handful of key workflows across your application ( less than 10)
• Brittle and expensive to maintain so choose wisely
• Never let them break
• Don’t be afraid to throw them away and create new ones over time
30. Summary
• Lust –chasing shiney new technology & tools
• Gluttony - no circuit breakers to prevent cascading failures
• Greed – creating too many services with the wrong bounded contexts
• Sloth – creating a distributed monolith
• Wrath – ignoring the wrath of distributed systems
• Envy – your build and deploy process must be a joy to behold
• Pride – fooled into thinking you don’t need proper tests
