EFS
Amazon Elastic File System (EFS) Amazon Elastic File System (EFS) is a fully managed, scalable, and elastic network file system (NFS) designed for use with AWS services and on-premises resources. It provides shared file storage that can be accessed concurrently by thousands of EC2 instances or other compute services. Amazon EFS provides highly optimized file…
AWS EC2 Instance Storage
Instance store is ephemeral block storage. This is preconfigured storage that exists on the same physical server that hosts the EC2 instance and cannot be detached from Amazon EC2. Instance store is generally well suited for temporary storage of information that is constantly changing, such as buffers, caches, and scratch data. It is not meant…
EBS Volume Types
EBS volumes fall into two primary categories: Comparison of EBS Volume Types Volume Type Use Case Size Range Max IOPS Max Throughput Baseline Performance Durability (%) Cost Efficiency Multi-Attach Support General Purpose SSD (gp3) Balanced workloads like web servers, virtual desktops 1 GiB – 16 TiB 16,000 1,000 MB/s 3,000 IOPS (baseline), configurable IOPS 99.8…
EBS Snapshots
EBS Snapshots Backups of Amazon Elastic Block Store (EBS) volumes, which provide a way to save the state of your data at a specific point in time. Snapshots are incremental in nature, meaning only the changes made to the data since the last snapshot are stored, making them efficient in terms of storage space and…
EC2 Autoscaling
EC2 Auto Scaling is a service in Amazon Web Services (AWS) that automatically adjusts the number of EC2 instances in an Auto Scaling group based on your specified policies. The goal of EC2 Auto Scaling is to ensure that you have the right number of EC2 instances running to handle the load for your application,…
EC2 User data and Metadata
EC2 User Data Feature in Amazon Web Services (AWS) that allows you to automate the initialization of an EC2 instance when it is launched. It enables you to provide custom scripts or commands that run automatically on the first boot of the instance. When using the AWS CLI or SDK, user data is typically base64…
EC2 Amazon Machine Images
Kinds of Images Golden Images Image typically created by an organization to ensure consistency, security, and efficiency across multiple environments. The golden image is a template that includes the necessary software, patches, settings, and configurations that an organization requires for its workloads. Consistency: Ensures that every new instance launched from the image will have the…
EC2 Lifecycle
Only an EBS-backed instance can be stopped and started, instance store-backed instance cannot be stopped and started. Rebooting an instance is equivalent to rebooting an operating system. The instance remains on the same host computer and maintains its public DNS name, private IP address, and any data on its instance store volumes. It typically takes…
VM Import/Export
AWS provides the VM Import/Export service, which facilitates the import and export of virtual machine images to and from AWS. This service enables you to import existing virtual machine images from your on-premises environment to Amazon EC2 instances and export EC2 instances back to virtual machine images for use outside AWS. VM Import/Export Overview:
