Intro to AWS EKS: Orchestrating Scalable and Resilient Kubernetes Workloads in the Cloud

As organizations embrace containerization and microservices architecture, managing and scaling containerized workloads efficiently becomes crucial. Amazon Elastic Kubernetes Service (EKS) provides a fully managed Kubernetes service, enabling you to deploy, manage, and scale containerized applications using the power and flexibility of Kubernetes in the AWS cloud environment. In this comprehensive blog post, we will explore AWS EKS in detail, covering its high-level architecture, use cases, and weighing its pros and cons to help you make informed decisions when considering EKS for your container orchestration needs.

AWS Elastic Block Store Volume Types

EBS Volume Type refers to the different types of Elastic Block Store (EBS) volumes that are available in Amazon Web Services (AWS). EBS volumes are virtual hard drives that can be attached to EC2 instances, providing persistent block-level storage for applications and data.

There are different EBS volume types that provide varying levels of performance, durability, and cost, allowing users to choose the best option for their specific workload.

AWS Elastic Block Store

Elastic Block Store (EBS) is a block-level storage service provided by Amazon Web Services (AWS) that allows you to create and attach persistent block storage volumes to your Amazon Elastic Compute Cloud (EC2) instances. It provides highly available and durable block-level storage volumes that can be used with Amazon EC2 instances to store data.

EBS volumes are replicated within an Availability Zone (AZ) to provide redundancy and durability. You can also take snapshots of EBS volumes, which are stored in Amazon S3, to provide a backup of your data. EBS volumes can be attached to EC2 instances as block devices, allowing you to use them as a hard drive or to store data for databases, file systems, and other applications.

Intro to AWS Security Groups

AWS Security Group is a virtual firewall that controls inbound and outbound traffic for Amazon Elastic Compute Cloud (EC2) instances and other resources in Amazon Web Services (AWS). It acts as a virtual firewall that regulates traffic based on rules that you define.

Each AWS Security Group is associated with one or more instances, and you can specify the inbound and outbound traffic rules for that group. You can use security groups to allow or deny traffic from specific IP addresses, protocols, or ports. You can also create rules that allow traffic from other security groups, enabling you to control access to different resources within your VPC.

Intro to AWS EC2 Instance Store

Amazon Elastic Compute Cloud (EC2) Instance Store is a type of local disk storage that is physically attached to an EC2 instance. It provides temporary block-level storage for instances that require high-speed, low-latency access to data, such as database or cache workloads.

EC2 Instance Store is ideal for use cases that require high-performance data access and fast data transfer rates, such as transaction processing, web applications, and Hadoop clusters. EC2 Instance Store can provide higher I/O performance compared to Amazon Elastic Block Store (EBS) volumes, but it has some limitations.

Intro to EC2

Amazon Elastic Compute Cloud (EC2) is a web service provided by Amazon Web Services (AWS) that enables users to provision and manage virtual machines (VMs) in the cloud. It provides scalable computing capacity in the cloud, allowing users to quickly and easily launch virtual machines with a variety of operating systems and software configurations.

With EC2, users can choose from a wide range of instance types optimized for different types of workloads, including general-purpose, compute-optimized, memory-optimized, and storage-optimized instances. EC2 also provides several features and capabilities, including the ability to configure security groups and network settings, attach storage volumes, and scale up or down as needed.
