> Operational Excellence
This involves running and monitoring your systems effectively to deliver business value while continuously improving processes and procedures. Key practices include automating operations (performing operations as code), maintaining clear documentation, planning for potential failures, and implementing changes frequently in small, reversible steps to minimize risk. Gaining insights into workload operations is crucial.
> Security
A fundamental aspect of cloud readiness is the ability to protect your information, systems, and assets. This requires robust risk assessment and mitigation strategies. Best practices involve applying security measures at every layer of your architecture, protecting data both when it's stored (at rest) and when it's being transferred (in transit), and automating security processes wherever possible.
> Reliability
Cloud-ready systems are designed to be dependable. This means building architectures capable of automatically recovering from infrastructure or service disruptions and mitigating issues like misconfigurations or network problems. A key component is the ability to dynamically acquire computing resources to meet fluctuating demand, ensuring availability without manual intervention.
> Performance Efficiency
This pillar focuses on using computing resources efficiently to meet system requirements and maintain that efficiency as demand changes and technologies evolve. It involves selecting the right resource types and sizes, monitoring performance, and making data-driven decisions to optimize your architecture.
> Cost Optimization
Being cloud-ready means managing costs effectively to achieve business outcomes without overspending. This involves understanding spending patterns, using cost-effective resources, analyzing expenditures over time, and scaling resources to meet business needs without waste.
