Implementing OpenAPI and GraphQL Services with gRPC
Tim Burks, Software Engineer at Google
Implementing OpenAPI and GraphQL services with gRPCTim Burks
Behind every API there's code. REST and GraphQL are powerful interface abstractions but are not so great for writing code (we’re still looking for the programming language where every command is a GET, POST, PUT, or DELETE). When programmers work, they are usually making function calls, and an RPC framework like gRPC allows those functions to be written in a mixture of languages and distributed among many servers. This means that gRPC can be a great way to implement REST and GraphQL APIs at scale. We’ll share open source projects from Google that can be used to implement OpenAPI and GraphQL services with gRPC and give you hands-on experience with both.
Presented at the 2019 API Specifications Conference.

Initially delivered at LA RubyConf 2013, this presentation describes how cutting-edge technology helped to triple performance and drastically cut costs in a mobile social game. Juan Pablo Genovese, a Ruby Architect from Altoros Systems Argentina, explains how, despite the extremely tight budget, the customer managed to:
- go from ~450 req/s to ~1300 req/s
- reduce the number of EC2 application servers from four to one
- provide fast and reliable video uploading and processing
- achieve very easy scaling with automation
while maintaining all the functions of the original RoR app.

GraalVM and MicroProfile - A Polyglot Microservices SolutionRoberto Cortez
Microservices need to support many programming languages, requiring both a language-agnostic network protocol and a polyglot runtime environment. In addition, microservices written in one language may need to use APIs written in some other language.
Using a traditional CRUD application implemented as a polyglot solution (Java, JavaScript, Python and Ruby) on GraalVM, this presentation demonstrates how MicroProfile JWT, MicroProfile Metrics, MicroProfile Rest Client, MicroProfile Health Check, and more can provide architecture-level interoperability across concerns.

Developing APIs over a RESTful interface with JSON payloads is kind of the de-facto standard nowadays, but it still lacks an easy way to build it with a well-defined interface and document it to be used by others. What if we can leverage gRPC's fast, type-safe, and modern way of building APIs and still be able to provide an interface over REST/JSON ? Check this talk to find out how.

Globus Connect Server Deep Dive - GlobusWorld 2024Globus
We explore the Globus Connect Server (GCS) architecture and experiment with advanced configuration options and use cases. This content is targeted at system administrators who are familiar with GCS and currently operate—or are planning to operate—broader deployments at their institution.
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.
Code reviews are vital for ensuring good code quality. They serve as one of our last lines of defense against bugs and subpar code reaching production.
Yet, they often turn into annoying tasks riddled with frustration, hostility, unclear feedback and lack of standards. How can we improve this crucial process?
In this session we will cover:
- The Art of Effective Code Reviews
- Streamlining the Review Process
- Elevating Reviews with Automated Tools
By the end of this presentation, you'll have the knowledge on how to organize and improve your code review proces
