Monitoring the Dynamic Nature of the Cloud [FutureStack16 NYC]
0 likes701 views
This document discusses monitoring applications in dynamic cloud environments like Docker and AWS Lambda. It notes that traditional server monitoring is insufficient for dynamic infrastructure where components have short lifecycles. It recommends monitoring at the application level using tools that provide end-to-end visibility from code to infrastructure. Monitoring is needed for component lifecycles and to maintain accountability between code and cloud resources.

Cloud architecture is integral to the application architecture Developers deeply involved in cloud activities
- 43. Change is speeding up Dynamic Cloud enables better applications faster. Traditional Data Center Good Cloud Data Center Better Dynamic Cloud Best The way you’ve done things in the past won’t work in the future.
- 44. Dynamic Cloud Things happen faster because of… EC2 Server running application / processes Docker container Process running a command This is HARD
- 45. Dynamic Cloud EC2 Server running application / processes Docker container Process running a command Lambda Function performing a task or operation
- 47. Microcomputing & AWS Lambda • Newest entrance to the “dynamic cloud” • Provides event driven compute capabilities
- 48. Microcomputing & AWS Lambda • No infrastructure to provision • Massively shared infrastructure
- 49. Why use Lambda? Lambda scripts Run in response to a state change or action in the cloud Stateless, “filters” Perform quick actions Virtually no startup/shutdown cost
- 50. AWS Lambda S3 Bucket Dynamo DB API Gateway SQS RESOURCESSOME • Takes an event from an AWS resource (A Trigger)
- 51. AWS Lambda S3 Bucket Dynamo DB API Gateway SQS RESOURCESSOME Lambda Script • Takes an event from an AWS resource (A Trigger) • Creates an instance to execute Lambda Instance
- 52. AWS Lambda S3 Bucket Dynamo DB API Gateway SQS RESOURCESSOME S3 Bucket API Gateway SQS RESOURCESSOME Lambda Script • Takes an event from an AWS resource (A Trigger) • Creates an instance to execute • Can impact original or different AWS Resource Lambda Instance
- 53. AWS Lambda S3 Bucket Dynamo DB API Gateway SQS RESOURCESSOME S3 Bucket API Gateway SQS RESOURCESSOME Lambda Script Lambda Instances • Takes an event from an AWS resource (A Trigger) • Creates an instance to execute • Can impact original or different AWS Resource • Any number of instances can run at a time
- 54. Lambda example #1: Photo Management App
- 55. Photo management application S3 Bucket Image Import • Photos uploaded to S3 Upload File User
- 56. Photo management application S3 Bucket Image Import S3 Bucket Image Thumbnails Lambda Script • Photos uploaded to S3 • Lambda script creates thumbnails Upload File View Thumbnail User
- 57. Photo management application Image Database S3 Bucket Image Import S3 Bucket Image Thumbnails Lambda Script Lambda Script • Photos uploaded to S3 • Lambda script creates thumbnails • Lambda script updates metadata in database Upload File View Thumbnail User
- 58. Photo management application Image Database Application Upload File S3 Bucket Image Import S3 Bucket Image Thumbnails Lambda Script App Interactions View Thumbnail Lambda Script • Photos uploaded to S3 • Lambda script creates thumbnails • Lambda script updates metadata in database • Application only has to deal with metadata editing, not photo / file management User
- 59. Lambda example #1: Mobile Game App
- 60. Mobile game platform API Gateway Lambda Script Lambda Script Lambda Script Mobile Phone Application Users Database • Cloud platform hosts an API for mobile app – API Gateway • Lambda scripts implement the API • Lambda scripts manipulate database • Extremely high scale possible – No infrastructure
- 61. Monitoring Lambda Scripts Less like server monitoring / More like web application monitoring We Care About We Don’t Care About • Run time (average, extremes – TP90/TP99) • Statistical metrics • Error rates and other deviations from norm • “Drill down” into individual “runs” • Details about all ”runs” • Server / infrastructure metrics
- 62. Monitoring Lambda More like application performance monitoring than infrastructure monitoring
- 63. Monitoring Lambda More like application performance monitoring than infrastructure monitoring
- 64. Change is speeding up Dynamic Cloud enables better applications faster. The rate of change is increasing… Traditional Data Center Good Cloud Data Center Better Dynamic Cloud Best The way you’ve done things in the past won’t work in the future.
- 65. Monitoring just the server Worked when rate of change was low… EC2 Instance Application & Application Microservices Server OS Server (Virtual) Hardware AWS CONSOLE CloudWatch
- 66. Monitoring just the server Insufficient in the cloud: • Rate of change is faster • Problems come up quicker • “Server” isn’t a server anymore • “Provisioning” isn’t provisioning anymore You need top to bottom monitoring… You need full stack accountability...
