MICROSERVICES? MICROSERVICES? Martin Fowler - a definition of this new architectural term: bit.ly/ms-definition Microservice architecture patterns and best practices bit.ly/ms-patterns Resources & Reading List bit.ly/ms-resources if you're not familiar with microservices, here's your home work (links at the last slide)

MICROSERVICES MICROSERVICES IN PRODUCTION IN PRODUCTION everybody talks about microservices, (the theory, the tooling, best practices, etc ...) but you rarely see the complexity involved

EXPECTATION EXPECTATION as a team starts to venture into building a new product, they might start thinking about the architectural design pattern and see it in abstract terms

EXTENDED EXPECTATIONS EXTENDED EXPECTATIONS as development intensifies, the initial theory quickly evolves, more microservices are discovered (they're like pokemons, new ones keep showing up!) and throughout more tooling is introduced (cranes in pic)

REALITY STRIKES REALITY STRIKES the best laid plans of mice and men often go awry

REALITY CHECK REALITY CHECK in reality, microservices are huge in scale and require a lot of tooling and support

User Service Movie Service Rating Service SIMPLE MOVIE SIMPLE MOVIE RECCOMENDATIONS RECCOMENDATIONS Reeco Service quick example things start off simple

User Service Movie Service Rating Service SIMPLE MOVIE SIMPLE MOVIE RECCOMENDATIONS??? RECCOMENDATIONS??? Reeco Service services have to talk to each other! - mark movie as watched - check if movie exists before applying rating - check current user permissions

SCALING SIMPLE MOVIE SCALING SIMPLE MOVIE RECCOMENDATIONS RECCOMENDATIONS LB LB LB LB enter load balancers, service registery and discovery tools

GROWTH STAGE GROWTH STAGE microservices quickly increase in number to serve different business functions teams start forming around or from microservices and APIS

REFACTOR! REFACTOR! V2 V2 V2 V2 new hot shot joins the team, decides to re-write everything!

DEPENDENCIES! DEPENDENCIES! V2 V2 V2 V2 don't forget, services need to talk to each other

SECURITY & AUTHENTICATION SECURITY & AUTHENTICATION V2 V2 V2 V2 security can be achieved on the network layer, but also through authentication to ensure user action impersonation

LOGGING? LOGGING? V2 V2 V2 V2 you wanna know what's going on, don't you? and how about debugging a user transaction across all those microservices?

BRAIN OVERLOAD! BRAIN OVERLOAD! tables be flipping

ENTER KONG ENTER KONG V2 V2 V2 V2 GETKong.org Kong is designed to solve the problem of abstracting common microservices & API management functionality

WHAT IS KONG? WHAT IS KONG? $ curl -X POST 127.0.0.1:8001/apis \ --data 'name=movies.v1' \ --data 'upstream_url=http://lb1.movies/' \ --data 'request_path=/v1/movies' $ curl -X POST 127.0.0.1:8001/apis \ --data 'name=movies.v2' \ --data 'upstream_url=http://lb2.movies/' \ --data 'request_path=/v2/movies' Open-source management layer for APIs Built with Nginx, OpenResty, Lua Configurable Through a RESTful API add powerful functionality through plugins kong nodes are stateless and horizontally scalable, with built-in auto-discovery and clustering

KONG PLUGINS KONG PLUGINS $ http POST :8001/apis/movies.v1/plugins \ name=loggly config.key=SECRET $ http POST :8001/apis/movies.v1/plugins \ name=rate-limiting config.hour=500 config.minutes=100 $ http POST :8001/apis/movies.v1/plugins \ name=cors config.origin=* config.methods=GET,PUT $ http POST :8001/apis/movies.v1/plugins \ name=galileo config.service_token=SECRET $ http POST :8001/apis/movies.v1/plugins \ name=ssl config.cert=@/local/path/to/cert.pem \ config.key=@/local/path/to/cert.key $ http POST :8001/apis/movies.v1/plugins \ name=oauth2 config.scopes=email,phone,address \ config.mandatory_scope=true plugins are functional lua modules that are triggered at certain points during the request life-cycle with the ability to inspect, modify, and transform the request and response objects (here I'm using HTTPie for the examples)

SCENARIOS SCENARIOS VPN Vendors - as external facing api gateway - as internal microservices orchestration - as vendor shield - can even chain kong

GALILEO GALILEO The Analytics Platform for Monitoring, Visualizing and Inspecting API & Microservice Traffic

GAIN INSIGHT GAIN INSIGHT Timeseries Charts See trends data down to the minute with our timeseries charting that shows how usage is changing and visually spot any anomalies. Error View Keep track of client and server errors and who is causing them so you can debug and handle the issue before it becomes a problem.

GAIN INSIGHT GAIN INSIGHT Custom Filtering Filter the data down to exactly what you care about and learn how clients are requesting your services and how servers are responding. Consumer Usage Get a clear picture of an individual consumers requests to figure out how they are using your services and which endpoints are most important.
