6 Benefits of the Cloud
- Trade Capex for variable expense (OPEX)
- Benefit from massive economies of scale
- Stop Guessing Capacity
- Increase Speed and Agility
- Stop spending money running and maintaining data centers
- Go Global in minutes
A service that checks applications for security vulnerabilities and deviations from best practices
Amazon Inspector
A service that provides intelligent threat detection for your AWS infrastructure and resources.
Amazon GuardDuty
Which compute option reduces costs when you commit to a consistent amount of compute usage for a 1-year or 3-year term?
Savings Plans. Note Reserved instances do not require a commitment. Key word is consistent amount of compute
ElastiCache
Amazon ElastiCache is a service that adds caching layers on top of your databases to help improve the read times of common request
EC2 Instance stores
Instance stores are ideal for temporary data that does not need to be kept long term. When an Amazon EC2 instance is stopped or terminated, all the data that has been written to the attached instance store is deleted.
EC2 Instance Store has a better I/O performance, but data is lost if: the EC2 instance is stopped or terminated, or when the underlying disk drive fails.
AWS Direct Connect
AWS Direct Connect is a service that enables you to establish a dedicated private connection between your data center and VPC (virtual private cloud).
The private connection that AWS Direct Connect provides helps you to reduce network costs and increase the amount of bandwidth that can travel through your network.
Virtual Private Gateway
A virtual private gateway enables you to establish a virtual private network (VPN) connection between your VPC and a private network, such as an on-premises data center or internal corporate network. A virtual private gateway allows traffic into the VPC only if it is coming from an approved network.
Amazon SageMaker
Amazon SageMaker is a service that enables you to quickly build, train, and deploy machine learning models
DeepRacer
AWS DeepRacer is an autonomous 1/18 scale race car that you can use to test reinforcement learning models.
Availability Zone (AZ)
An AZ consists of one or more discrete data centers, each with redundant power, networking, and connectivity housed in separate facilities. Each AZ is isolated but the AZs in a region are connected through low-latency links.
AWS Cost Explorer
Easy to use interface that lets you visualize, understand and manage your AWS costs and usage over time
5 Characteristics of Cloud Computing
- On-demand Self Service
- Broad Network Access
- Multi-Tenancy and Resource Pooling
- Rapid elasticity and Scalability
- Measured Service
IAM Roles
Some AWS service will need to perform actions on your behalf. To do so, you assign permissions to AWS services with IAM Roles.
Elastic File Share
Amazon EFS is a fully managed service that makes it easy to set up, scale, and cost-optimize file storage in the Amazon Cloud
Glue
AWS Glue is a fully managed extract, transform, and load (ETL) service that makes it easy for customers to prepare and load their data for analytics.
Fargate
Fargate allows you to launch Docker containers on AWS, and you don’t need to provision and maintain the infrastructure (=no EC2 instances to manage). It is serverless.
AWS CloudFormation
AWS CloudFormation gives developers and systems administrators an easy way to create and manage a collection of related AWS resources, provisioning and updating them in an orderly and predictable fashion.
