AWS Core Services Flashcards
Compute Service
Service that enables to use cloud-based virtual machines for workloads
EC2
Amazon Elastic Compute Cloud
Web service that provides resizable compute capacity in the cloud
EC2 Use Cases
Web application hosting
Batch processing
Web services endpoint
Dekstop in cloud
EC2 Instance Types
Define processor, memory, and storage type
Cannot be changed without downtime
General Purpose Compute, memory, storage optimized (3 diff types) Accelerated computing (ML)
Pricing based on instance type
Root device type EC2
Instance Store - If you sut it down it will go away
Elastic Block Store - it will stay
EC2 AMI
Amazon Machine Image
instance including config, os, and data
Shared across multiple accounts
Create your own custom ami’s and marketplace
EC2 Purchase Option Reserved Instance
Discounts if you commit to a period of time
Capacity reservation
EC2 Reserved Instance Cost Model*
All Upfront - cheapest
Partial Upfront - middle
No upfront
EC2 Savings Plan Instance*
supports EC2, Lambda,
EC2 Spot Instance
90% discount over on-demand prices
Spot price per availability zone
If your bid is higher, then you can launch
Temrinated if not
Dedicated Host
Physical Server
Software Licensing or Something
EC2 Purchase Options Summary
If you have instance consistent and always needs standard or convertible reserved
If you have batch processing, leverage Spot instances
If you have an inconsistent need for instances use On Demand
Specific per-server license or compliance requirment use Dedicated Host
Leveraging lambda alongside use Savings Plan
Predictable but not steady workload use Scheduled Reserved Instance
AWS Elastic Beanstalk
Automates process of deploying and scaling workloads on EC2 (PaaS)
Supports specific set of technologies
Leverage existing AWS services
Only pay for the other services you leverage
Handles, load balancing, scaling, and monitoring
Java, .Net, PHP, Node.js, Python, Ruby, Go, Docker
Elastic Beanstalk Features
Monitoring
Deployment
Scaling
EC2 Customization
Elastic Beanstalk Use Cases
Deploy with minimal knowledge of other services
Reduce overall maintenance needed for the application
Few customizations are required
AWS Lambda
Run code without provisioning or managing servers Only pay for compute time you consume 128m to 3008mb memory available Integrates with AWS services Enabled event-driven workflows Primary service for serverless
AWS Lambda Advantages
Reduced maintence requirments
Enables Fault tolerance
Scales based on demand
Pricing is based on usage
Networking and CDS
Amazon Route 53 Amazon VPC AWS Direct Connect Amazon API Gateway Amazon CloudFront Elastic Load Balancing
Amazon Virtual Private Cloud (VPC)
Virtual network we can define Enables virtual network in AWS Support public and private subnet Connect to your data center Other VPC's
AWS Direct Connect
Data Center -> AWS
Amazon Route 53
Domain Name Service, DNS
Global service (not regional)
Highly available
Enables global resource routing (send to the server on what you want, ex; if it fails route to new server)
Elastic Load Balancing
Distributes traffic among multiple targets Integrates EC2, ECS, and Lambda Supports one or more AZ's in a region Application Load Balancer Network Load Balancer Classic Load Balancer
Scaling on EC2
Vertical Scaling - Scale-up instance to a larger instance w/ additional resources
Horizontal Scaling - Scale-out and add additional instances to handle the demand of the application
Amazon CloudFront and API Gateway
CloudFront - CDN, enables users to get content from the server closest to them, static/dynamic content, utilizes edge locations, adv security like AWS Shield for DDoS and …
API Gateway- Fully managed API management service, directly integrates with multiple AWS services, provides monitoring & metrics on API calls, supports VPC and on-premise something…
AWS Global Accelerator
Sends users traffic through AWS global network to improve internet user performance by up to 60%
Uses edge locations to route traffic through AWS network, not the internet
Distance between user and initial endpoint is minimized
Traffic optimized using AWS network
first byte latency, jitter, throughput,
superior fault tolerance not relying on DNS resolution
AWS Global Accelerator Use Cases
Non-HTTP Protocal (MQTT, VOIP, or UDP)
Requires static IP
Instant Failover
AWS File Storage Services
S3 S3 Glacier Elastic Block Store Elastic File System Snowball Snowmobile
S3
Store files as objects in buckets
Provides different storage classes for different use cases
Across multiple availability zones
Enables URL access for files
Offers configurable rules for data lifecycle
Servce as a web soemthing
S3 Non-archival Storage Class
S3 Standard - Default for requtnly accessed
S3 Intelligent-tIeiring - Moves to the correct storage class
S3 Standard-IA is for infrequently accessed data with the stand resilience
S3 One Zone - Infrequrntly access datas that is only stored in one AZ
S3 Intelligent Tiering
Auto moves files based on access
Frequent of Infrequent
S3 Lifecycle Policies
Objects can transition or expire
Expiration can delete objects
Policies can also factor in versions of a specific object
S3 Transfer Acceleration
Uses edge locations to upload faster
S3 Glacier
Designed for archiving data
Configurable retrieval times
Send files directly through licecycle
S3 Glacier vs S3 Glacier Deep Archive
designed for archival data, retrieved in hours, fee per GB retrieved
S3 Glacier , 90 day mininmum, retrieved in minutes, over 5 times less expensive
180 day minimum storage, retrieved in hours, 23 times less expensive than standard
EBS, Elastic Block Store
Connected to a single EC2 instance Enables redundancy within a zone Snapshots of data Offer encryption multiple volume types
EBS Volume Types
General Purpose SSD - Cost effective for general workloads
Provisioned IOPS SSD - High performance for low latency apps
Throughput Optimized HDD - Designed for frequently accessed data
Cold HDD - less frequently accessed workloads
Elastic Filesystem
NFS File system Designed for Linux PB's of data Multiple AZ's Standard and Infrequent Access Configurable
Amazon FSx for Window File Server
Native Windows File system
SSD for low latency
Data Transfer with Snowball
Physically migrate petabytes to cloud Physical device delivered by AWS connect snowball to your network device returned by local carrier Loads into s3
Snow mobile
