Pre-requisite: AWS EBS
Amazon Elastic Beanstalk is a fully managed service provided by AWS that makes it easy to deploy, run, and scale web applications and services developed with Java, .NET, PHP, Node.js, Python, Ruby, Go, and Docker on familiar servers such as Apache, Nginx, and IIS. With Elastic Beanstalk, you can simply upload your code and the service automatically handles the deployment, from capacity provisioning, load balancing, and auto-scaling to application health monitoring. Elastic Beanstalk also integrates with other AWS services, such as Amazon RDS for databases, Amazon S3 for storage, and Amazon CloudWatch for monitoring, allowing you to build a highly scalable and fault-tolerant application.
EBS (Elastic Bean Stalk) Volumes
An Elastic Block Store (EBS) volume is a type of block storage provided by AWS that can be used to store data for Amazon Elastic Compute Cloud (EC2) instances. When you create an Elastic Beanstalk environment, it automatically creates and attaches an EBS volume to the Amazon EC2 instances that are part of the environment.
EBS Volumes are stored separately from your Amazon EC2 instances, which means that if an instance is terminated, its attached EBS volume persists and can be attached to a new instance. When you create an Elastic Beanstalk environment, you have the option to specify the type of EBS volume that should be used.
Here are some key terminologies that are used in AWS Elastic Beanstalk:
- Application: A collection of environments and versions of an application.
- Environment: A specific deployment of an application version in Elastic Beanstalk. This could be a development, staging, or production environment.
- Application Version: A specific version of the code that is deployed to an environment.
- Elastic Beanstalk Environment: The underlying infrastructure that runs the application, such as Amazon EC2 instances, Auto Scaling groups, and load balancers.
- Environment Tier: The web server environment runs on the environment. It can be either “Web Server” or “Worker”
- Platform: The programming language, web container, and operating system used to run the application. Elastic Beanstalk supports a variety of platforms, including Java, .NET, PHP, Node.js, Python, Ruby, Go, and Docker.
- Configuration: The settings that affect the way an Elastic Beanstalk environment runs, such as the number of Amazon EC2 instances, the instance type, and the load balancer settings.
- Health: The overall health of an environment, represented by a color (green, yellow, or red) that indicates whether the environment is working as expected.
Types of EBS Volumes available
- General Purpose (SSD): provides a balance of cost and performance for a wide variety of workloads.
- Provisioned IOPS (SSD): provides high-performance storage with consistent and low-latency I/O operations.
- Magnetic: provide a lower-performance storage option for infrequently accessed workloads.
Each of these types of EBS volumes has a different IOPS (I/O operations per second) rate, throughput, and storage capacity. You can choose the type of EBS volume that best fits the requirements of your application and can change this option after the environment is created. You can also configure Elastic Beanstalk to use a specific size for the EBS volume, based on the available storage for your instances.
In summary, Elastic Beanstalk creates EBS volumes and attaches them to the instances of your environment, these volumes can have different types based on the performance needs of your application, and you have the possibility to change them and size them as per your requirements.
Uses of EBS(Elastic Bean Stalk) in AWS?
When you use Elastic Beanstalk, you simply upload your application code, and Elastic Beanstalk automatically handles the deployment, from capacity provisioning, load balancing, and auto-scaling to application health monitoring. You can also use Elastic Beanstalk to deploy different environments, such as development, staging, and production, and easily promote code between environments.
Here’s an explanation of how Elastic Beanstalk can be used in AWS:
- Deployment of Applications: You can use Elastic Beanstalk to deploy your web applications and services written in a variety of programming languages and frameworks, such as Java, .NET, PHP, Node.js, Python, Ruby, Go, and Docker.
- Infrastructure Management: Elastic Beanstalk automatically provisions and manages the underlying infrastructure, such as Amazon EC2 instances, Auto Scaling groups, and load balancers. Elastic Beanstalk provides an easy-to-use web interface and command-line tools to monitor and manage your applications and environments.
- Automatic Scaling: Elastic Beanstalk can automatically scale your application based on demand and configure health monitoring to ensure that your application is always available.
- Ease Integration: Elastic Beanstalk can integrate with other AWS services, such as Amazon RDS for databases, Amazon S3 for storage, and Amazon CloudWatch for monitoring, allowing you to build a highly scalable and fault-tolerant application.
- Controlling and Monitoring: With Elastic Beanstalk you can also monitor your app logs and use some predefined environment variables to configure your application. Additionally, it offers an easy way to update your application or to roll back when an update goes wrong.
Elastic Beanstalk allows you to focus on writing code for your application, rather than worrying about the underlying infrastructure, making it an ideal service for developers who want to quickly deploy and scale their web applications on AWS.
In conclusion, Elastic Beanstalk gives you an easy way to store and manage data for your applications and provides your application with the necessary performance and storage capacity. And also gives you the flexibility and control to configure the size and type of storage according to the needs of your application.
