Organizations adopt microservices when the logistical overhead of coordinating teams against a monolith becomes so large that it starts affecting product velocity. Microservices are a way to release that organizational/logistical friction, at great technical cost.
If microservices are implemented incorrectly or used as a band-aid without addressing some of the root flaws in your system, you’ll be unable to do new product development because you’re drowning in the complexity.
Microservices are about scaling teams, not scaling tech
Announcing Envoy Mobile. This is a fascinating development: Lyft’s Envoy proxy / service mesh has been widely adopted across the industry as a server-side component for adding smart routing and observability to the network calls made between services in microservice architectures. “The reality is that three 9s at the server-side edge is meaningless if the user of a mobile application is only able to complete the desired product flows a fraction of the time”—so Lyft are building a C++ embedded library companion to Envoy which is designed to be shipped as part of iOS and Android client applications. “Envoy Mobile in conjunction with Envoy in the data center will provide the ability to reason about the entire distributed system network, not just the server-side portion.” Their decision to release an early working prototype and then conduct ongoing development entirely in the open is interesting too. # 18th June 2019, 6:42 pm
Domains Search for Web: Instant, Serverless & Global (via) The team at Zeit are pioneering a whole bunch of fascinating web engineering architectural patterns. Their new domain name autocomplete search uses Next.js and server-side rendering on first load, then switches to client-side rendering from then on. It can then load results asynchronously over a custom WebSocket protocol as the microservices on the backend finish resolving domain availability from the various different TLD providers. # 26th January 2018, 1:14 am
now-ab. Intriguing example of a Zeit Now microservice: now-ab is a Node.js HTTP proxy which proxies through to one of two or more other Now-deployed applications based on a cookie. If you don’t have the cookie, it picks a backend at random and sets the cookie. Admittedly this is the easiest part of implementing A/B testing (the hard part is the analytics: tracking exposures and conversions) but as an example of a microservice architectural pattern this is fascinating. # 16th November 2017, 11:03 pm
