Designing For Elasticity and Scalability.

OpsWorks

• Configuration managed service (Automated Deployment)
  • Configure (code-based).
    • Instance deployment.
    • Service deployment.
    • Application deployment.
  • Operate:
    • Application development/updates.

OpsWorks Services:

1. OpsWorks Stacks
   • Initial OpsWorks mode, a collection of layers.
     • Any AWS service, any runtime environment.
2. OpsWork Chef Automate
   • Cookbooks contain recipes.
   • Recipes equivalent to layers (defined config settings).
3. OpsWorks Puppet
   • Master servers.
     • Pre-configured modules.
     • Modules equivalent to layers.

Prebuilt Layers: Ruby, PHP, Node.js, Java, Amazon RDS, Ha Proxy, MySQL.

**Use stacks on-prem, chef and puppet are cloud-only.

Cognito

• User identity and synchronization service (SSO).
• Public identity providers are leveraged (Google, Facebook, Amazon).
• Private identity providers can be leveraged (Active Directory with SAML).
• Based on Open Standards (OAuth 2.0, SAML 2.0, OpenID connect)
• Profile Management Console (scales to millions of users).
• Controls access to AWS resources, define roles, map users to roles.

Elastic MapReduce (EMR)

• Distributes processing across clusters.
  • Implements a managed Hadoop framework.
• Pulls data from S3 buckets.
• Process data on EC2 instances.
• User defines the number of needed clusters.

EMR Cluster Nodes

• Master
  • Coordinates job distribution across core and task nodes.
• Core
  • Runs tasks assigned by the master node.
  • Stores data in the cluster.
• Task
  • Runs only tasks that do not store data.

CloudFormation

• Rapid deployment of full, multi-instanced solutions.
• Mirror existing internal architectures.
• Take advantages of templates created by others.
• Can effectively take a snapshot of your deployment/current AWS services and load it into a template (CloudFormer).

CloudFormation Properties;

• AWS periodically updates properties that can be configured in CloudFormation.

CloudWatch

• Monitors the cloud and on-prem systems.
• Can build dashboard (ie security, cost, ect…)
• Built from logs & events.
• Events can trigger alarms.

Trusted Advisor

• Service that evaluates your environment and can recommend improvements.
• Security improvements included in free tier.
• With payment, get cost & performance improvement.

Organizations

• Collection of AWS accounts.
• Centralized:
  • One management interface.
  • Billing.
  • Account management.
• No additional charge for use.

Organizations Units (OUs)

• Hierarchical account management.
• Can nest up to five level deep.
• Can apply policies at the OU Level.
