The goal of this pillar is to understand the operational processes behind your applications to enable continuous improvement. This includes understanding business objectives, identifying errors and issues, automating processes, and continuously measuring and monitoring your applications to make effective decisions. By implementing best practices in operations and automation, the "Operational Excellence" pillar helps make your applications more agile, efficient, and cost-effective.

This pillar aims to ensure that your applications and data in the cloud are protected adequately. The framework provides best practices and recommendations to detect and mitigate threats by applying the appropriate security mechanisms such as encryption, access controls, network isolation, and more. By implementing this pillar, you can achieve a higher level of security for your applications and data in the cloud.

Reliability in the AWS Well-Architected Framework refers to how dependable and stable your system is. A reliable application is not only important for users, who need to rely on an application being available, but also for businesses, as frequent outages can negatively impact users and business operations. Within the Reliability pillar, existing methods for error detection, monitoring, and incident management are reviewed and optimized to ensure the system remains stable and reliable.

Performance Efficiency in the AWS Well-Architected Framework refers to how efficiently an application or system performs its work. For example, if you operate an application that opens very slowly or responds to requests very slowly, this may indicate poor performance efficiency. On the other hand, an application that has more computing power available than it needs will result in unnecessary costs. Within the framework, there are proven methods that help us improve the performance efficiency of your application to achieve a better user experience without incurring unnecessary costs.

The Cost Optimization pillar in the AWS Well-Architected Framework focuses on optimizing the costs of your workloads on AWS without compromising on performance, scalability, or security. Our goal is to help you effectively utilize your AWS resources to avoid unnecessary costs. We support you in reducing your AWS bills by selecting the right instance types, adhering to resource limits, automating resource provisioning and decommissioning, and more. By implementing these best practices, you only pay for what you actually need without having to compromise on important functions or resources.

Sustainability is the latest of the six pillars of the AWS Well-Architected Framework. We assist you in assessing and optimizing the environmental impact of your AWS workloads. Our common goal is to create a sustainable architecture that is not only environmentally friendly but also efficient, cost-effective, and reliable. Therefore, it is important to consider sustainability as a crucial factor in the planning of your AWS workloads.
