Reducing Costs with AWS Cloud:

Capacity Adjustment (B):

Elasticity: AWS allows you to scale your resources up or down based on demand, which means you only pay for what you use. This reduces the cost of over-provisioning resources.

Auto Scaling: Automatically adjusts compute capacity based on usage, ensuring cost efficiency.

Eliminating On-Premises Costs (E):

No Infrastructure Maintenance: By using AWS, businesses do not need to invest in physical infrastructure or handle maintenance, reducing both capital and operational expenditures.

Managed Services: AWS offers managed services that reduce the need for in-house technical staff to manage and maintain infrastructure.

AWS Benefits

Understanding Operational Excellence: The Operational Excellence pillar of the AWS Well-Architected Framework focuses on running and monitoring systems to deliver business value and continuously improving supporting processes and procedures.

Key Concepts of Operational Excellence:

Small, Reversible Changes: Making changes in small, incremental steps allows for easier troubleshooting and rollback if issues arise.

Regular Updates: Regularly updating components ensures that systems stay up-to-date with the latest features, security patches, and performance improvements.

Automation: Implementing automation for deployments, updates, and monitoring to reduce human error and increase efficiency.

Continuous Improvement: Encouraging continuous learning and process improvement to enhance operational processes.

Implementing Operational Excellence:

Deployment Automation: Use CI/CD pipelines to automate deployments and ensure that changes can be rolled back if necessary.

Monitoring and Logging: Implement comprehensive monitoring and logging to track system health and performance.

Incident Response: Develop a robust incident response plan to handle issues quickly and efficiently.

Documentation and Training: Maintain thorough documentation and provide training to ensure teams can effectively manage and improve operations.

According to the AWS shared responsibility model, AWS is responsible for the security of the cloud, while customers are responsible for the security in the cloud. This means that AWS is responsible for the physical servers, networking, and operating system that run Lambdafunctions, while customers are responsible for the security of their code and AWS IAM to the Lambda service and within their function1. Customers need to manage the code within the Lambda function, such as writing, testing, debugging, deploying, and updating the code, as well as ensuring that the code does not contain any vulnerabilities or malicious code that could compromise the security or performance of the function23. References: 2: AWS Lambda - Amazon Web Services (AWS), 3: AWS Lambda Documentation, 1: Amazon CLF-C02: What is customer responsibility under AWS … - PUPUWEB

Economies of scale are the cost advantages that result from increasing the scale of production or operation. In cloud computing, economies of scale are achieved by pooling resources and sharing them among multiple users, which reduces the unit cost of computing and storage. One of the benefits of economies of scale in cloud computing is increased speed and agility, which means the ability to deploy applications faster and respond to changing business needs more quickly. Cloud computing allows users to access computing resources on demand, without having to invest in expensive infrastructure or wait for lengthy provisioning processes. This enables users to scale up or down as needed, experiment with new ideas, and deliver value to customers faster123. References:
