  1. 1Acts as a server, get one whenever you need to accommodate higher volumeEc2 instance
  2. 2Repeated tasks same across companiesUndifferentiated heavy lifting of IT
  3. 3Three cloud computing deployment modelscloud-based, on-premises, and hybrid
  4. 4Data centers, physical servers, and other resources that you need to invest in before usingupfront expense
  5. 5When you only pay for computing services that you useVariable expense
  6. 6Service that lets you run code with needing to manage or provision serversLambda
  7. 7Another name for on-premises deploymentPrivate cloud deployment
  8. 8Sharing underlying hardware between virtual machinesMultitenancy
  9. 9Responsible for managing multitenancy, so ec2s are separated from each other on the hostHypervisor
  10. 102 operating systems you can put ec2Windows, Linux
  11. 11Making ec2 as big or small as you needVertical scaling
  12. 12Type of service where you leverage ec2sCompute as a service (CaaS)
  13. 13Configurations available for ec2 instanceOperating server, application servers, or application
  14. 14The specific hardware configuration of your ec2 instanceinstance type
  15. 15Different types of Ec2 instancesGeneral purpose, compute optimized, storage optimized, memory optimized, accelerated computing
  16. 16Ec2 instance type that provides balanced resources, diverse workloads, web servers, and code repositoriesGeneral purpose Ec2 instance type
  17. 17Ec2 instance type best for compute intensive tasks, gaming servers, high performance computing (HPC), and scientific modelingCompute optimized instances
  18. 18Ec2 instance best for memory intensive tasksMemory optimized instances
  19. 19Ed2 instance best for floating point number calculations, graphics processing, data patterns matching, and utilize hardware acceleratorsAccelerated computing type
  20. 20Ec2 instance type best for high performance workloads for locally stored dataStorage optimized
  21. 21Metric that measures the performance of a storage typeIOPS (input/output operations per second)
  22. 22Amazon Ec2 purchase optionsOn-Demand, savings plan, reserved instances, spot instances, dedicated hosts
  23. 23Ec2 purchase option that are ideal for short-term, irregular workloads that cannot be interrupted. No upfront costs or minimum contracts apply.On-demand instances
  24. 24Ec2 purchase option that enable you to reduce your compute costs by committing to a consistent amount of compute usage for a 1-year or 3-year term. This term commitment results in savings of up to 66% over On-Demand costs.Savings plans
  25. 25Ec2 purchase option that are a billing discount applied to the use of On-Demand Instances in your account. You can purchase Standard Reserved and Convertible Reserved Instances for a 1-year or 3-year term, and Scheduled Reserved Instances for a 1-year term. You realize greater cost savings with the 3-year option.Reserved instances
  26. 26Ec2 instance purchase type that is ideal for workloads with flexible start and end times, or that can withstand interruptions. Spot Instances use unused Amazon EC2 computing capacity and offer you cost savings at up to 90% off of On-Demand prices.Spot instances
  27. 27physical servers with Amazon EC2 instance capacity that is fully dedicated to your useDedicated hosts
  28. 28Beginning with only the resources you need and designing architecture to automatically respondscalability
  29. 29Service for if you want automatic scalingAmazon Ec2 auto scaling
  30. 30Type of scaling that responds to changing demandDynamic scaling
  31. 31Type of scaling that automatically schedules the right number of ec2 instances based on predictive demandpredictive scaling
  32. 32Number of amazon ec2 instances that launch automatically after configuring the auto scalingminimum capacity
  33. 33What happens if you do not specify the desired number of ec2 instancesSets to minimum capacity
  34. 34Evently distributes workload from application traffic across ec2 instances - routes and processes requestselastic load balancer
  35. 35Placing messages into a bufferMessaging and queuing
  36. 36If one message fails whole operation failsTightly coupled architecture
  37. 37If there is a message queu acting as a buffer, type of architectureLoosely coupled architecture
  38. 38Allows you to send store and receive software messages at any momentamazon sqs
  39. 39Data contained in amazon sqs messagepayload
  40. 40Where messages are stored until they are processed between applicationsamazon sqs
  41. 41a channel for messages to be deliveredamazon sqs topic
  42. 42where you create an sns topic, configured subscribers to topic, then publish messages to subscribers. can fan out one message to multiple subscriberspublished subscribe model
  43. 43application with tightly coupled components such as databases, servers, user interface, etc.monolithic application
  44. 44application design where application components are loosely coupledmicroservices approach
  45. 45Two services that facilitate application integrationAmazon (Simple Queue Service) SQS and Amazon Simple Notification Service (SNS)
  46. 46publish/subscribe serviceAmazon SNS
  47. 47What can be subscribers for Amazon SNSLambda, web servers, email addresses, etc
  48. 48When you cannot see or access the underlying infrastructureServerless
  49. 49Allows you to upload code, configure trigger, and service waits for trigger. When code is detected, code is run in managed environmentLambda
  50. 50a widely used platform to deliver software in containersdockers
  51. 51package for your code, a standard way to package your application's code and dependencies into a single objectcontainer
  52. 52help you manage your containersorchestration tools
  53. 53serverless compute platform for ecs or eks; manages your server infrastructure for youfargate
  54. 54If trying to host traditional app and want full access to osuse ec2
  55. 55if don't want to manage underlying environment at all, use thisserverless aws lambda
  56. 56if looking to use container dockets useorchestration tools
  57. 574 steps to how lambda works1. upload code to lambda
    2. set code to trigger from an event source
    3. lambda runs code only when triggered
    4. only pay for the compute time you use
  58. 58highly scalable, high-performance container management system that enables you to run and scale containerized applications on AWS; supports docker containersAmazon Elastic Container Services (ECS)
  59. 59open-source software that enables you to deploy and manage containerized applications at scaleKubernetes
  60. 60a fully managed service that you can use to run Kubernetes on AWS.Amazon Elastic Kubernetes Service (EKS)
