Automate integration tests.



Automate the path to production.



Increase velocity and reduce risk with frequent, small batch sizes.



Choose architectures that are less likely to resist automation.

ObservabilitySLI/SLOReliabilityAvailability


Verma et al, “Large-scale cluster management at Google with Borg”

“Almost every task run under Borg contains a built-in HTTP server that publishes information about the health of the task and thousands of performance metrics (e.g., RPC latencies).”

Observability


Spring Boot Actuator – Health$ curl -s http://my-app/health | jq { "status": "UP", "diskSpace": { "status": "UP", "total": 1056858112, "free": 907612160, "threshold": 10485760 } }


Spring Boot Actuator – Metrics$ curl -s http://my-app/metrics | jq { "mem": 734352, "mem.free": 459292, "processors": 4, "instance.uptime": 17072859, "uptime": 17078694, "systemload.average": 0.6, "heap.committed": 664064, . . .


Service Level Indicators are data about the operational characteristics of a service.

SLIs


Service Level Objectives set reliability expectations based on SLIs.

SLOs


If a system should be 99.99% available then it can be 0.01% unavailable.

If we have error budget left development can take risks. If not we have to fix it.

SLAs – Error Budgets


Minimize the amount of errors so we can launch code as fast as possible.

Error Budgets – Aligned Incentives


Service Level Objective: 99.99% of requests return under 50ms.

The error budget allows for 0.01% of requests to exceed the SLO.

“Ways in which things go right are special cases of the ways in which things go wrong.”


Susan J. Fowler, “Production-Ready Microservices”

“Every µService at Uber should be stable, reliable, scalable, fault tolerant, performant, monitored, documented, and prepared for any catastrophe.”


A distributed system cannot simultaneously have consistent views of the data at each node and availability of the data at each node if the network becomes partitioned.

Raymond Blum and Rhandeev Singh, “Site Reliability Engineering”

“Data integrity is a function of availability of a given entity over its lifetime. This is analogous to system uptime and even more critical.”



“Data availability must be a foremost concern of any data-centric system.”



“From the user’s point of view, data integrity without expected and regular data availability is effectively the same as having no data at all.”


Availability is a User Experience problem.


Building software like SRE—with a focus on observability, reliability, and availability—makes you cloud-native.

Cloud-Native Roadshow Closing


Wikipedia Article “Operability”

“Operability is the ability to keep an equipment, a system, or a whole industrial installation in a safe and reliable functioning condition, according to pre-defined operational requirements.”

What is operability?


Kenny Bastani, Pivotal

“A microservice is an application small enough that an engineer new to the source code can reason about it in a day or less.”

Microservice


The ability to deploy to production whenever the organization chooses without anyone setting themselves on fire.

Continuous Delivery


Engineer your operations.

SRE Culture


It doesn’t matter how beautiful your architecture is, how easy deployment is, or how great your culture is if production is a tire fire.

Pivotal Cloud Foundry


No CEO Ever

“I appreciate the progress you made on not delivering anything.”

Undifferentiated Heavy Lifting


Unique Business Value is the tools, systems, and processes which improve the unique value your organization provides.

The only thing that matters


Acacio Cruz and Ashish Bhambhani, “Site Reliability Engineering”

“Provide product development with a platform of SRE-validated infrastructure, upon which thy can build their systems. This platform will have the double benefit of being both reliable and scalable.”


PCF is the first platform in CRE review.
