Explore automation in site reliability engineering, from infrastructure as code and application deployment to continuous monitoring, automated testing, and guardrails that ensure secure, scalable operations.

Compare traditional operations with decentralized DevOps and two-pizza team models, and learn how to align information technology structure, process, and governance with business objectives.

Explore how agile aligns with site reliability engineering for interactive, incremental, minimum viable product style delivery. Use continuous feedback, faster incident response, and cross-functional collaboration to enhance customer-centric reliability.

Explore reliability foundations, trade-offs with innovation, and the core principles and practices of site reliability engineering, including SRE roles, responsibilities, and SLAs.

Explore how reliability underpins site reliability engineering by ensuring a system performs consistently, is available when needed, durable, fault-tolerant, and predictable through monitoring.

Balance reliability and innovation by measuring total development time using team velocity and points per day, guided by agile planning to estimate feature delivery and time to market.

Apply SRE tenets by balancing engineering focus with change management, monitoring, and capacity planning to sustain reliable services while respecting SLAs and budgets.

Examine seven Esri principles and their practical implementation to build a reliable environment. Learn about practices that translate these principles into action, including monitoring, post-mortems, testing, and capacity planning.

Explore the SRE role as high-skilled generalists who design resilient, highly available architectures, monitor and automate to reduce toil, collaborate with development, and support release management and security guardrails.

Examine availability levels from two to seven nines, and how error budgets and outages guide reliability decisions in site reliability engineering.

Master the seven Sri principles for site reliability engineering—embracing risks, service level objectives, eliminating toil, monitoring, automation, release engineering, and simplicity.

Embrace risk by mapping and assessing risks, balancing reliability with innovation, and using error budgets to enable experimentation through defined service availability.

Explore SLOs, SLIs and SLAs within site reliability engineering, defining measurable targets for latency, uptime, and error budgets, with standardized indicators and customer expectations.

Eliminate toil by automating repetitive, manual operational tasks, redefining engineers' focus toward engineering. Automate patches, deployments, access, and rollback to improve standards, fail fast recovery, and prevent burnout.

Establish monitoring as the foundation of observability, collecting metrics and logs to give real-time insights into latency, traffic, errors, health, and reliability, and trigger proactive alarms with runbooks and post-mortems.

Leverage automation to boost efficiency, reliability, and scale while reducing human error; establish simple, standard templates and rules to automate provisioning, patching, monitoring, and incident response.

Learn how release engineering drives automated continuous delivery from commit to deployment. Explore versioning strategies, testing, and deployment models like canary and rolling using Git workflows and infrastructure as code.

keep systems simple by avoiding overengineering, establish a foundation, and build modular, lego-like components for monitoring, logging, high availability, autoscaling, and backup with backward compatibility, clear documentation, and streamlined releases.

Explore techniques and methods for achieving reliability goals in SRE, grounded in core principles and best practices, including monitoring, incident response, post-mortem and root cause analysis, testing, and capacity planning.

Master incident response by mobilizing the on-call team quickly, defining roles and escalation, and building playbooks and a knowledge base to diagnose, test, and reduce outages.

Define relevant KPIs and SLIs, set meaningful thresholds, correlate metrics, and apply anomaly detection and automation to reduce alert fatigue in monitoring.

Perform post-mortem and root cause analysis to improve reliability by reviewing incidents, identifying root causes, and implementing actionable improvements.

Master testing across infrastructure, applications, and user workflows by embedding unit, integration, and system tests into the deployment pipeline, enabling canary and blue-green deployments, rollback planning, and ensuring right sizing.

Master capacity planning for reliable, high-performance systems by forecasting traffic, projecting capacity in real time, and using auto scaling, load balancers, queues, and circuit breakers.

Examine development practices in automation, tooling, and code to boost reliability, covering infrastructure code, provisioning, configuration tooling, modules, and the role of code reviews and pipelines.

Create a lightweight, modular, robust product that consolidates SRE automations into a reusable framework, ensuring retro compatibility, simplicity, and integration with monitoring, testing, and capacity planning.

Learn how to adopt site reliability engineering in your organization, balancing cultural change, best practices, and tooling to avoid common silos and drive successful adoption.

Learn how to initiate SRE adoption with a cultural transformation, leadership buy-in, and team training, then implement tooling, standards, and automation to boost reliability, efficiency, and business agility.

Decide and validate your tooling strategy by assessing processes, then select infrastructure as code (Terraform, CloudFormation, CDK), configuration management, monitoring (Prometheus, Grafana, Datadog), and ITSM integration that fits your team.

Overcome challenges in adopting SRE by fostering shared responsibility, breaking silos, and standardizing tooling; build cross-functional teams, strengthen communication, and align with SLOs through leadership guidance and training.
