This document discusses blockchain and APIs. It provides information about an upcoming series of API conference events in various global locations. It then discusses how blockchain networks like Solana function as globally accessible computers through mechanisms like proof-of-work, validators, and transactions. It notes Solana has attributes like planet-size state, natural transactionality, and permissionless composability. It outlines Solana's architecture including clients, RPC nodes, validators, programs, and accounts. It also discusses Solana's JSON RPC API and how instructions allow programs to interact on the blockchain. It highlights a Solana client project called Better Call Sol.

INTERFACE, by apidays - Scaling APIs

apidays

This document discusses strategies for scaling APIs as development teams grow. It recommends getting teams aligned on API design standards through a council and using linters to encourage adherence to standards. Centralizing the API gateway and analytics helps avoid duplicating work and provides consistent rate limiting and monitoring across APIs. The future may see more simplification of API design processes and centralized management of linters.

gRPC：更高效的微服務介面

William Yeh

Title: gRPC: A more efficient microservice interface. Presented in: Taiwan Cloud Edge Summit 2020 (台灣雲端大會) https://cloudsummit.ithome.com.tw/speaker.html#s7262 Description: 在 Web service 時代，基於 HTTP 的 REST 簡單易用，是最流行的 API 服務介面。然而，到了微服務時代，服務互連現象更為頻繁緊密，以前 REST 的優點卻變成缺點：過於簡單的模型，欠缺基本的服務治理；過於陽春的 HTTP，欠缺高效的傳輸介面。新一代的 gRPC，則是在 HTTP/2 的基礎上，盡量維持簡單易用的特性，又具備微服務世界該有的服務治理與高效傳輸。本演講將示範 gRPC 的工作流程：介面定義、編程、測試、雲端應用實務，讓你可以開始嘗試導入 gRPC。

apidays LIVE India 2022_India DevInfra Opportunity.pdf

apidays

This document discusses trends in the global cloud services market and the growth of the developer infrastructure sector in India. It notes that spending on development infrastructure is one of the largest and fastest growing segments in software as a service. In India, there are now 8 unicorns and multiple growth-stage startups in the developer infrastructure sector. As these markets mature, companies are evolving their go-to-market strategies from inside sales to product-led and community-led models. For India to become a global leader in developer infrastructure, the document argues it needs to focus on building out mission-critical infrastructure, developing talent, and strengthening global ecosystems.
