10. Miscellanies – Yannick's non-Bakery

for Apache Kafka (alternative for Amazon Kinesis Data Streams)
Fully managed, with data stored in EBS for as long as needed (longer than 1 year)
Or Amazon MSK serverless, which no capacity concerns
Differences with Amazon Kinesis Data Streams
- Message size is not limited in 1MB(default)
- Topics with Partitions in Kafka = Shards in Data Streams
- MSK can only add Partition, but Data Streams can split and merge Shards
- PlainText or In-flight TLS encryption; Data Streams can only in-flight TLS

Simple E-mail Service for sending marketing e-mails (like a Marketo or ConstantContact)

an application / system can handle greater loads by adapting.
- Vertical, to increase instance size
- Horizontal, also called as “elasticity”, to increase number of instances

running your application / system in at least 2 data centers (== Availability Zones)

allow multiple SSL certificates onto one web server (to serve multiple websites), only works for ALB & NLB and CloudFront

(opensource) provides a single set of APIs, libraries, agents, and collector services
- collects distributed traces and metrics from applications
- also collects metadata from AWS resources and services
- Auto-instrumentation Agents
- Migrate from X-Ray to AWS Distro for Temeletry if wants to standardize with open-source APIs from Telemetry or send traces to multiple destinations (AWS and partners) simultaneously

using Signature v4 (SigV4) to send credentials (access key & secret key)
- HTTP Header option (signature in Authorization header)
- Query String option, ex: S3 pre-signed URLs (signature in X-Amz-Signature)

a managed service that is commonly used in chaos engineering, and not for application development. It enables you to perform fault injection experiments on your AWS workloads to improve the performance and resiliency of your applications

used to efficiently run hundreds of thousands of batch computing jobs in AWS; mostly used for ML model training, simulation, and analysis at any scale

is for executing tasks. Helps developers build, run, and scale background jobs; but it does not provide serverless orchestration to multiple AWS resources

allows you to engage with your customers across multiple messaging channels.
primarily used to send push notifications, emails, SMS text messages, and voice messages.

enable connected devices to run AWS Lambda functions, execute predictions based on machine learning models, keep device data in sync, and communicate with other devices securely even without an Internet connection.

provides automatic continuous backups of your DynamoDB table data. Point-in-time recovery (PITR) backups are fully managed by DynamoDB and provide up to 35 days of recovery points at a per second granularity.

DR approaches
- Backup and restore = lowest cost, just create backups
- Pilot Light = small part of core services that is running and syncing data or documents
- Warm Standby = scaled down version of a fully functional environment that is actively running
- Multi-site = on-prem and in AWS in an active-active configuration
For disaster recovery in a different region, create a AMI from your EC2 instance and copy it into a 2nd region.

increases availability and performance improve the performance of your network traffic by utilizing the AWS global infrastructure instead of the public Internet.
can be expensive
runs over AWS global network
directs traffic to optimal endpoints across multiple regions
By default, provides you with 2 static IP addresses that are anycast from the AWS edge network. You can migrate existing IPv4 (/24) IPs rather than creating new.

primarily used to provide real-time guidance to help you provision your resources following AWS best practices but does not handle logging or compliance.

gain visibility into their cloud spending, identify cost-saving opportunities, and make informed decisions about resource allocation and optimization
Steps of Cost Allocation
- STEP ONE: create user-defined tags with key-value pairs that reflect attributes such as project names or departments to ensure proper categorization of resources
- STEP TWO: apply these tags to the relevant resources to enable tracking
- STEP THREE: enable the cost allocation tags in the Billing console
- (AFTER) STEP FOUR: Configure tag-based cost and usage reports (AWS Cost Allocation Reports) for detailed analysis in Cost Explorer
AWS Budgets is typically used for setting cost and usage limits and receiving alerts; more about monitoring and controlling costs rather than detailed tracking and reporting

Serverless Component	Max Timeout	Comments
API Gateway	50 milliseconds – 29 seconds	Configurable
Lambda Function	900 seconds (15 minutes)	Also limited to 1,000 concurrent executions. If not handled, can lead to throttling issues.
DynamoDB Streams	40,000 write capacity units per table
S3	No timeout by default, can be configured to 5-10 seconds	Unlimited objects per bucket

AWS App Mesh = for application networking for microservices applications
AWS Resource Access Manager = share a Transit Gateway connection (only?) with other AWS accounts
AWS Server Migration Service (SMS) is for migrating virtual machines
AWS CodeStar quickly develop, build and deploy applications on AWS
Amazon Lex builds conversational interfaces into an application using voice and text
Amazon EMR allows researchers, scientists, businesses, etc. to process vast amounts of data using hosted Hadoop running on EC2 and S3
AWS Import/Export send HDDs with data to AWS and they import the data into S3
Amazon Connect: call centre
Amazon QuickSight: BI
Amazon Neptune: interactive graphs of DBs
