Microservices describe a way to design software applications as suites of independently deployable services. Key characteristics include organizing services around business capabilities, treating applications as products rather than projects, designing for failure, and decentralizing governance and data. Services communicate through lightweight protocols like HTTP and messaging and aim to be smart endpoints with dumb pipes. Infrastructure is automated through testing, deployment pipelines and monitoring for failure recovery. While microservices add complexity, the approach aims to improve scalability, flexibility and resilience over traditional monolithic architectures.
Design Patterns for Micro Service ArchitectureSarah Elson
Imagine breaking down a single function unit into multiple mini-service units. That is exactly what microservices do to the traditional monolithic architecture. But, there is more to it than meets the eye. Microservices are the go-to solution for all the major software development projects.
But even though it serves a major purpose, there are certain challenges across the way which need to be addressed. And as one design a microservice architecture along the way, one learns several microservice design patterns which can not only improve the performance but also ease the life of the developer. But before we delve deeper into the architecture design patterns, let’s understand the basic principles to keep in mind when we design a microservice architecture.

Architecting for speed: how agile innovators accelerate growth through micros...Jesper Nordström
In a world where software has become the key differentiator, enterprises are forced to transform the way they build, ship and run software in order to stay in the game. Competitive pressure requires applications to be rapidly and continuously upgraded with nonstop availability, and companies that lack the capacity to experiment, innovate and get new features out quickly, will be at disadvantage.
This is driving many IT organisations to adopt the software design model known as microservices architecture, which quickly is gaining traction as a new way to think about structuring applications, and is changing the fundamentals of enterprise application management.
Managing complex enterprise systems is a challenge and many enterprises still sit on large, monolithic applications with huge unmanageable codebases that have become increasingly difficult to maintain. Adopting a microservices architecture where applications instead are built as suites of services enables them to not only become more agile but also to cut costs and increase stability.

The Reality of Managing Microservices in Your CD PipelineDevOps.com
As we shift from monolithic software development practices to microservices, our well-designed CD pipeline will need to change. Microservices are small functions, deployed independently and linked via APIs at run-time. While these differences seem minor, they actually have a large impact on your overall CD structure. Think hundreds of workflows, small of any builds and the loss of a monolithic 'application.'

First Steps with Globus Compute Multi-User EndpointsGlobus
In this presentation we will share our experiences around getting started with the Globus Compute multi-user endpoint. Working with the Pharmacology group at the University of Auckland, we have previously written an application using Globus Compute that can offload computationally expensive steps in the researcher's workflows, which they wish to manage from their familiar Windows environments, onto the NeSI (New Zealand eScience Infrastructure) cluster. Some of the challenges we have encountered were that each researcher had to set up and manage their own single-user globus compute endpoint and that the workloads had varying resource requirements (CPUs, memory and wall time) between different runs. We hope that the multi-user endpoint will help to address these challenges and share an update on our progress here.
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.

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?

2. The term "Microservice Architecture" describes a particular
way of designing software applications as suites of
independently deployable services. There are certain
common characteristics around organization around business
capability, automated deployment, intelligence in the
endpoints, and decentralized control of languages and data.
3. • Characteristics of a Microservice Architecture
• Componentization via Services
• Organized around Business Capabilities
• Products not Projects
• Smart endpoints and dumb pipes
• Decentralized Governance
• Decentralized Data Management
• Infrastructure Automation
• Design for failure
• Evolutionary Design
• Are Microservices the Future?
5. Characteristics of a Microservice Architecture
Componentization via Services
Our definition is that a component is a unit of software that is
independently replaceable and upgradeable.
We define libraries as components that are linked into a program
and called using in-memory function calls, while services are out-
of-process components who communicate with a mechanism
such as a web service request, or remote procedure call.
6. Characteristics of a Microservice Architecture
Componentization via Services
Using services like this does have downsides. Remote calls are
more expensive than in-process calls, and thus remote APIs need
to be coarser-grained, which is often more awkward to use. If you
need to change the allocation of responsibilities between
components, such movements of behavior are harder to do when
you're crossing process boundaries.
7. Characteristics of a Microservice Architecture
Organized around Business Capabilities
Large monolithic applications can always be modularized around
business capabilities.
The necessarily more explicit separation required by service
components makes it easier to keep the team boundaries clear.
8. Characteristics of a Microservice Architecture
Products NOT Projects
Most application development efforts that we see use a project model:
• deliver some piece of software;
• the software is handed over to a maintenance organization and the
project team that built it is disbanded.
Microservice proponents tend to avoid this model, preferring instead the
notion that a team should own a product over its full lifetime.
Smaller granularity of services can make it easier to create the personal
relationships between service developers and their users.
9. Characteristics of a Microservice Architecture
Smart endpoints and dumb pipes
Enterprise Service Bus (ESB), where ESB products often include
sophisticated facilities for message routing, choreography,
transformation, and applying business rules.
The microservice community favours an alternative approach:to be
as decoupled and as cohesive as possible, receiving a request,
applying logic as appropriate and producing a response.
10. Characteristics of a Microservice Architecture
Smart endpoints and dumb pipes
The two protocols used most commonly are HTTP request-
response with resource API's and lightweight messaging
• The best expression of the first is "Be of the web, not behind the
web" (Ian Robinson). Teams use the principles and protocols
that the world wide web is built on.
• Simple implementations such as RabbitMQ or ZeroMQ
The biggest issue in changing a monolith into microservices lies in
changing the communication pattern.
11. Characteristics of a Microservice Architecture
Decentralized Governance
• Build it / run it
• Teams are responsible for all aspects of the software they build
including operating the software 24/7
Being woken up at 3am every night by your pager is certainly a
powerful incentive to focus on quality when writing your code.
12. Characteristics of a Microservice Architecture
Decentralized Governance
Not every problem is a nail and not every solution a hammer.
You want to use Node.js to standup a simple reports page? Go for it.
C++ for a particularly gnarly near-real-time component? Fine. You
want to swap in a different flavour of database that better suits the
read behaviour of one component? We have the technology to rebuild
him.
Of course, just because you can do something, doesn't mean you
should- but partitioning your system in this way means you have the
option.
14. Characteristics of a Microservice Architecture
Decentralized Data Management
Decentralizing responsibility for data across microservices has
implications for managing updates. The common approach to dealing
with updates has been to use transactions to guarantee consistency
when updating multiple resources. This approach is often used within
monoliths.
15. Characteristics of a Microservice Architecture
Decentralized Data Management
Decentralizing responsibility for data across microservices has
implications for managing updates. The common approach to dealing
with updates has been to use transactions to guarantee consistency
when updating multiple resources. This approach is often used within
monoliths.
16. Characteristics of a Microservice Architecture
Infrastructure Automation
• Automated Tests
• Automate Deployment
19. Characteristics of a Microservice Architecture
Design for failure
A consequence of using services as components, is that applications
need to be designed so that they can tolerate the failure of services.
Any service call could fail due to unavailability of the supplier, the client
has to respond to this as gracefully as possible.
This is a disadvantage compared to a monolithic design as it introduces
additional complexity to handle it.
20. Characteristics of a Microservice Architecture
Design for failure
Since services can fail at any time, it's important to be able to detect the
failures quickly and, if possible, automatically restore service.
• Real-time monitoring of the application
• Business relevant metrics
Monitoring is vital to spot bad emergent behavior quickly so it can be
fixed.
21. Characteristics of a Microservice Architecture
Evolutionary Design
Change control doesn't necessarily mean change reduction.
If you find yourself repeatedly changing two services together, that's a
sign that they should be merged.
The Guardian website is a good example of an application that was
designed and built as a monolith, but has been evolving in a
microservice direction. The monolith still is the core of the website, but
they prefer to add new features by building microservices that use the
monolith's API.
