65. What Happened?
Rate of change
increased
Cost and size and
risk of change
reduced

66. Disruptor:
Continuous Delivery
with Microservices

67. A Microservice Definition
!
Loosely coupled service oriented
architecture with bounded contexts

68. If every service has to be
updated at the same time
it’s not loosely coupled

Loosely coupled service oriented
architecture with bounded contexts

69. If every service has to be
updated at the same time
it’s not loosely coupled
A Microservice Definition
!
Loosely coupled service oriented
architecture with bounded contexts
If you have to know too much about surrounding
services you don’t have a bounded context. See the
Domain Driven Design book by Eric Evans.

70. High Availability Patterns
● Business logic isolation in stateless micro-services
● Immutable code with instant rollback
● Auto-scaled capacity and deployment updates
● Distributed across availability zones and regions
● De-normalized single function NoSQL data stores
● See over 40 NetflixOSS projects at netflix.github.com
● Get “Technical Indigestion” trying to keep up with techblog.netflix.com

74. Cloud Native
Monitoring and
Microservices

75. Cloud Native
● High rate of change
Code pushes can cause floods of new instances and metrics
Short baseline for alert threshold analysis – everything looks unusual
● Ephemeral Configurations
Short lifetimes make it hard to aggregate historical views
Hand tweaked monitoring tools take too much work to keep running
● Microservices with complex calling patterns
End-to-end request flow measurements are very important
Request flow visualizations get overwhelmed

76. Microservice Based Architectures

79. Continuous Delivery and DevOps
● Changes are smaller but more frequent
● Individual changes are more likely to be broken
● Changes are normally deployed by developers
● Feature flags are used to enable new code
● Instant detection and rollback matters much more

80. Whoops! I didn’t mean that!
Reverting…
Not cool if it takes 5 minutes to see it failed and 5 more to see a fix
No-one notices if it only takes 5 seconds to detect and 5 to see a fix

83. Low Latency SaaS Based Monitors

84. Metric to display latency needs to be
less than human attention span (~10s)

85. Separation of Concerns
Bounded Contexts

86. Answers to Some
Common Questions

87. Reaction from Fortune 100 CTO:
“But Netflix has a superstar development team, we don’t!"

88. Reaction from Fortune 100 CTO:
“But Netflix has a superstar development team, we don’t!"
Adrian’s Response:
“Netflix hired them from you, and got out of their way…”

89. Where to Start with DevOps?
Enterprise Mobile Apps
Horizontal Team
App-Store Provisioning
APIs to Everyone
DevOps Already…

90. 1
Where to Start with Cloud?
