Study Notes
Configuring EC2 Instances
- You can select an AMI provided by AWS, the AWS Marketplace, or one of your own AMIs.
- You can launch multiple instances from a single AMI when you require multiple instances with the same configuration.
Operating Systems
- Amazon Machine Images (AMIs) are preconfigured with an ever-growing list of operating systems.
Adding Persistent Block Storage
- Persistent storage volume(s) can be added to an EC2 instance, working as a virtual HD using Amazon EBS.
- You can attach multiple EBS volumes to an instance.
- An EBS volume persists independently from the life of its associated instance.
- The root volume of the instance is an EBS volume.
Configuring Security Group
- Configuring a security group for an Amazon EC2 instance is essential.
- A security group is a set of virtual firewall rules that control the traffic for your instance.
Amazon EC2 Pricing Models
- There are four ways to pay for Amazon EC2 instances: On-Demand Instances, Savings Plans, Spot Instances, and Reserved Instances.
Amazon Storage
- Many clients who are just starting on their cloud journey often consider storage services in the cloud as a stepping stone to going cloud-native in the long run.
- To build a powerful cloud application, you need scalable storage.
- Access to AWS storage services is easy, and rather than procuring new storage hardware to host on-premises, it is often easier and cost-effective to use the services offered by a cloud vendor such as AWS.
Storage Options
- Block storage is an architectural design that enables the storage of data onto media such as a hard disk, in fixed-sized chunks.
- File storage architecture offers a centralized location for your corporate data, and files are stored in folders and sub-folders.
Snapshots of EBS Volumes
- The first backup of a volume backups all the data.
- Every next backup copies only a block of data that has changed since the last snapshot.
- You can copy snapshots to other Regions.
Hosting a Website on an EC2 Instance
- Major steps to host a website on an EC2 instance include creating an AWS account, creating and launching an instance, connecting to the instance, installing a web server, and uploading the website.
EBS Pricing
- The AWS Free Tier (12 months free) includes 30 GB of storage, 2 million I/Os, and 1 GB of snapshot storage with Amazon EBS.
- You can use the AWS Pricing Calculator to estimate costs.
EBS Volume Types
- When configuring your EC2 instance with an EBS volume, you need to select the type of volume, the amount of storage you wish to provision, and if you want to configure encryption on your EBS volume.
- There are different types of EBS volumes to choose from, including Solid State Drives (SSDs) and Hard Disk Drives (HDDs).
