AWS SysOps Training

System Operations on AWS is designed to teach those in a Systems Administrator or Developer Operations (DevOps) role how to create automatable and repeatable deployments of networks and systems on the AWS platform. The course covers the specific AWS features and tools related to configuration and deployment, as well as common techniques used throughout the industry for configuring and deploying systems.

Seven best practises for building systems with AWS:

Design for failure and nothing fails

• Avoid single points of failure
• Assume everything fails and design backwards

Loose coupling sets you free

• Design architectures with independent components
  • The more loosely they’re coupled, the bigger they scale
  • Design every component as a black box
  • Load balance clusters
  • Use a queue to pass messages between components

Implement elasticity

• Elasticity is a fundamental property of the cloud
• Don’t assume the health, availability, or fixed location of components
• Use design that are resilient to reboot and re-launch
• Bootstrap your instances
  • When an instance launches, it should ask “Who am I and what is my role?”
  • Favour dynamic configuration

Build security in every layer

• Security is a shared responsibility. You decide how to:
  • Encrypt data in transit and at rest
  • Enforce principle of least privilege
  • Create distinct, restricted Security Groups for each application role
    • Restrict external access via these security groups
• Use multi-factor authentication

Don’t fear constraints

• Need more RAM
  • Consider distributing load across machines or a shared cache
  • Better IOPS for databases?
    • Instead, consider multiple read replicas, sharing, or DB clustering
• Hardware failed or config got corrupted
  • “Rip and Replace” – Simply toss bad instances and instantiate replacement

Think parallel

• Experiment with parallel architectures

Leverage different storage options

• One size does not fit all
  • Object storage
  • Content delivery network/edge caching
  • Block storage
  • Relational database
  • NoSQL

Simplify using AWS services in your applications with an API tailored to your programming language or platform such as Browser, iOS, Android, Java, .Net, Node.js, PHP, Python, Ruby, Go, C++, AWS Mobile SDK, AWS IoT Device SDK etc.

Controlling of AWS services from the command line and automate service management with scripts by AWS Command Line Interface(CLI), AWS Tools for PowerShell, AWS SAM Local, Amazon BenStalk, Amazon EC2, and Amazon EC2 Container Service.
