AWS CLOUD PRACTITIONER 2024 EXAM WITH 100% VERIFIED
CORRECT ANSWERS
Advantages of Cloud Computing
- Go Global in minutes
- Stop spending money running and maintaining data centers
- Benefit from economies of scale
- Increase speed and agility
- Stop guessing capacity
- Trade Capital expense for variable expense
Benefits of Cloud Computing
- High Availability
- Elasticity
- Agility
- Durability
High Availability
designed to operate continuously without failure for a long time
Elasticity
don't have to plan ahead of time how much capacity you need, provision what you need
Agility
All the services you have access to help you innovate faster, giving you speed to market
Durability
data will remain intact without corruption
Infrastructure as a Service (IaaS)
Building Blocks that can be rented (like EC2)
Software as a Service (SaaS)
using a complete application, on demand, that someone offers to users
,Platform as a Service (PaaS)
develop software using web-based tools without worrying about the underlying
infrastructure
EC2
Elastic Compute Cloud. Amazon Elastic Compute Cloud (Amazon EC2) is a web
service that provides resizable compute capacity in the cloud. It is designed to make
web-scale cloud computing easier for developers. Reduces the time required to obtain
& boot new server instances to minutes.
On-Demand (EC2)
a fixed price in which you are billed down to the second (pay for what you use)
Spot (EC2)
enable you to bid whatever price you want for instance capacity, providing for even
greater savings if your apps have flexible start and end times. good for aps that are only
feasable at very low compute prices. users with urgent computing needs for large
amounts of additional capacity
Reserve Instances (EC2)
allows you to commit to a specific instance type in a particular region for 1-3 years
Use when:
- steady usage and can commit to 1-3 years
- pay upfront in order to receive discount
Dedicated Host (EC2)
allows you to pay for a physical server that is fully dedicated to running your instances
Horizontal Scaling
add or replace EC2 instances automatically based on need and changing demand
Vertical Scaling
upgrades the instance by adding more power (RAM/CPU) to an existing server
Lambda
Serverless compute service that lets you run code without managing servers
- Charged based on the duration and number of requests
- You are only responsible for your application code. AWS Manages servers, coding
environment, and language support
, - Even after the free-usage tier expires, you'll have access to 1 million free lambda calls
each month
Fargate
serverless compute engine for containers
Lightsail
compute service that is used to quickly launch preconfigured apps for small projects
Outposts
allows you to run cloud services in your internal data center (supports hybrid
deployment)
Batch
compute service that is used to process large workloads in smaller batches
S3
Highly available object storage service
- stored in buckets
- Offers unlimited storage with many storage classes
S3 Standard
general purpose storage across multiple AZs
- Use case: data with unknown or changing access pattern
S3 Standard-Infrequent Access (IA)
data accessed less frequently but requires rapid access
- Use Case: long-lived data, infrequently accessed, millisecond access when needed
S3 One Zone-IA
Like IA but stored in one AZ
- Use Case: re-creatable data, infrequently accessed with millisecond access,
availability and durability not essential
S3 Glacier
Long-term data storage and archival for lower costs
- Use Case: long-term backups, cheaper storage options
S3 Glacier Deep Archive
