    - - Choose the right purpose-built engine
      - Run fully managed databases
      - Achieve performance at scale
      - Rely on high availability and security
- - - - is a client–server architecture
      - in which presentation, application processing and data management functions are physically separated.
  - - - A high available architecture is when there are a number of different components, modules, or services that work together to maintain optimal performance, irrespective of peak-time loads.
      - often measured in the percentage of time that a service is available to users
    - - Fault-tolerant systems use backup components that automatically take the place of failed components
        
        no loss of service
        
        hardware
        
        software
        
        power
        
        maintains essential functions during minor failures, and in the event of a disaster
      - disaster recovery strategy
    - - Downtime
        
        A fault-tolerant system is expected to work continuously with no acceptable service interruption.
        
        A highly available system has a minimal allowed level of service interruption. For example, a system with “five nines” availability is down for approximately 5 minutes per year.
      - Scope
        
        High availability builds on a shared set of resources that are used jointly to manage failures and minimize downtime.
        
        Fault tolerance relies on power supply backups, as well as hardware or software that can detect failures and instantly switch to redundant components
      - Cost
        
        A fault tolerant system can be costly, as it requires the continuous operation and maintenance of additional, redundant components.
        
        High availability typically comes as part of an overall package through a service provider (e.g., load balancer provider).
  - - - measure of how closely connected two functions, modules or applications are
        
        Low
        
        good sign of a well architected system and good design practice
        
        high readability of code.
    - - synchronous
        
        it requires both sides to be always available, however, they don’t need to ‘know’ each other
        
        An ELB distributes incoming application traffic across multiple EC2 instances, in multiple Availability Zones
        
        without disrupting the overall flow of requests to your application.
        
        type of ELB
        
        Application Load Balancers
        
        work in between your web servers and the application servers,
        
        generally doing content-based routing
        
        nodes of an internal load balancer have only private IP addresses.
        
        internal load balancers can only route requests from clients with access to the VPC for the load balancer.
        
        Classic Load Balancers
        
        work in between the public Internet and your web servers.
      - asynchronous
        
        communication is achieved even if the receiver is not available.
        
        SQS
        
        provides a messaging queue infrastructure
        
        move data between distributed components of your applications that perform different tasks without losing messages or requiring each component to be always available.
