18. Confidential
Kubernetes
● Container orchestrator built around Docker
● “Have a datacenter on their laptop”
● Dev env == production env
● Multi-cloud
● Community convergence & 3rd party integrations

56. Microservices
● Smaller, simpler and easier to test
● Develop, deploy and run independently
● Organization can scale to many teams
57. Tradeoffs with Microservices
Pros Cons
Strong Modular Boundaries Distributed Systems
Independent Deployment Eventual Consistency
Diversity of Technology Operational Complexity
58. Fallacies of Distributed systems
● The network is reliable
● Latency is zero
● Bandwidth is infinite
● The network is secure
● The network is homogeneous

77. Istio Terminology
•Service: unit of (destination) application.
•Service Versions: variants of (destination) application binary.
•Service Registry: keeps track of pods/VMs of a service
•Virtual Service: rule defining what service to send a request to
•Destination Rule: rule defining what to do after destination
service is identified
88. Spring Cloud
Libraries that eliminate boilerplate code for Spring Boot applications.
Started by using established libraries and servers such as
● Netflix OSS (Eureka, Ribbon, Hystrix)
● Hashicorp Consul
● Apache Zookeeper
89. Level of abstraction

● Spring and Istio address the
problems of distributed
systems at different layers of
abstraction

92. Istio or Spring Cloud (or both?)
● What features do you want?
○ Who should be able to tune the values?
● Spring Cloud is more battle-tested
○ 4 years vs Istio GA’ed 1 year ago
● Provided by the platform (Istio), use it!
○ Polyglot envs especially benefit
