- - - - Operational excellence
        
        Is the ability to run and monitor systems to deliver business value and to continually improve supporting processes and procedures
        
        Design principles for operational excellence in the cloud include performing operations as
        
        Code
        
        Annotating documentation
        
        Anticipating failure
        
        Frequently making small, reversible changes
      - Security
        
        Is the ability to protect information, systems, and assets while delivering business value through risk assessments and mitigation strategies
        
        When considering the security of your architecture, apply these best practices
        
        Automate security best practices when possible
        
        Apply security at all layers
        
        Protect data in transit and at rest
      - Reliability
        
        Is the ability of a system to do the following
        
        Recover from infrastructure or service disruptions
        
        Dynamically acquire computing resources to meet demand
        
        Reliability includes
        
        Testing recovery procedures
        
        Scaling horizontally to increase aggregate system availability
        
        Automatically recovering from failure
        
        Mitigate disruptions such as misconfigurations or transient network issues
      - Performance Efficiency
        
        Is the ability to use computing resources efficiently to meet system requirements and to maintain that efficiency as demand changes and technologies evolve
        
        Evaluating the performance efficiency of your architecture includes
        
        Experimenting more often
        
        Using serverless architectures
        
        Designing systems to be able to go global in minutes
      - Cost Optimization
        
        Is the ability to run systems to deliver business value at the lowest price point
        
        Cost optimization includes
        
        Adopting a consumption model
        
        Analyzing and attributing expenditure
        
        Using managed services to reduce the cost of ownership
- - - - Upfront expenses include data centers, physical servers, and other resources that you would need to invest in before using computing resources
        
        Instead of investing heavily in data centers and servers before you know how you’re going to use them, you can pay only when you consume computing resources
    - - By using cloud computing, you can achieve a lower variable cost than you can get on your own
        
        Because usage from hundreds of thousands of customers aggregates in the cloud, providers such as AWS can achieve higher economies of scale
        
        Economies of scale translate into lower pay-as-you-go prices
    - - With cloud computing, you don’t have to predict how much infrastructure capacity you will need before deploying an application
        
        Example
        
        You can launch Amazon Elastic Compute Cloud (Amazon EC2) instances when needed and pay only for the compute time you use
        
        You can access only the capacity that you need, and scale in or out in response to demand
    - - The flexibility of cloud computing makes it easier for you to develop and deploy applications
        
        This flexibility also provides your development teams with more time to experiment and innovate
    - - Cloud computing in data centers often requires you to spend more money and time managing infrastructure and servers
        
        A benefit of cloud computing is the ability to focus less on these tasks and more on your applications and customers
    - - The AWS Cloud global footprint enables you to quickly deploy applications to customers around the world, while providing them with low latency
