Concept Dump: Operations and Cloud Infrastructure

• Operations and Cloud Infrastructure - “Data centers full of servers and hard drives that expose those resources to us.”
  • Load Balancer - “Distributes requests to servers without stressing out a single one.”
  • Database - “A way to store data without ever (hopefully) losing it and be able to request that data programmatically.”
  • Cache - “A way to store data temporarily since it could be lost if the cache crashes. Much faster than a database just less reliable.”
  • File Storage - “A way to permanently store files of arbitrary length or type.”
  • CDN - “Bunch of file servers that sit close to end-users which help speed up websites.”
  • Compute Resources - “Server that can run our code.”
  • DNS (Domain Name Service) - “Mappings between domain names and either other domain names or IP addresses.”
  • API (Application Programming Interface) - “Exposes a set of functionality or code that can be called from other code.”
  • Serverless - “Cloud-based service that we do not have to manage or configure.”
  • Queues - “Store and move data through a system to compute resources that can process it without a huge priority on time/latency.”
  • Event-Driven Architecture - “System architecture that focuses on using generated events from a user or from our system to trigger processing.”
  • Managed Service - “Service that has most configuration and routine maintenance done by the service provider (not us).”
  • Throughput - “Amount of events that can be processed in a given period of time.”
  • High Availability - “System that will not go down if one or several of its servers go down.”
  • Fault Tolerance - “System that knows how to handle a fatal error and self-heal.”
  • Asynchronous Processing - “Computing is done without a user needing to wait on it.”
  • Distributed Systems - “Group of code, servers, and services that work together without being on the same physical machine.”
  • Microservices - “Small pieces of code that run quickly and are reusable running on lots of small servers.”
