Amazon Elastic Compute Cloud ( Amazon EC2 )

Amazon Elastic Compute Cloud (EC2) is a web service that is part of Amazon Web Services (AWS) and is used to launch and manage virtual machines (VMs) in the cloud. These VMs, also known as instances, can be configured to run different operating systems and can be of various sizes depending on the computing power and storage required.

With EC2, users have the flexibility to choose the right type and size of instances for their application, and can easily scale up or down as the workload changes. Users can also configure and launch instances with custom configurations, such as specific software and security settings.

EC2 also provides features such as load balancing, automatic scaling, and monitoring to help users manage their instances. This allows users to easily handle increased traffic and handle failover without any interruption. With EC2, you pay for the resources you use, and can scale up or down as needed. With this, EC2 is a highly cost-effective solution for running applications and websites in the cloud.

8. Cost-Effective: With EC2, users pay only for the resources they use, and can scale up or down as needed, making it a cost-effective solution for running applications and websites in the cloud.
9. Elastic Block Store (EBS): EC2 instances can be launched with an Elastic Block Store (EBS) for storing data, it provides high-performance and low-latency storage for EC2 instances.
10. Elastic IP : EC2 instances can be launched with an Elastic IP (EIP) for providing a static IP address to access the instances from internet.

Instance states

Amazon Elastic Compute Cloud (EC2) instances have several states that indicate the current status of the instance. The most common states are:

1. Running: The instance is up and running, and can be accessed and used.
2. Stopped: The instance is not running, but the data on the instance’s storage volumes is still preserved. A stopped instance can be started again at any time.
3. Terminated: The instance is permanently terminated, and the data on the instance’s storage volumes is also deleted.
4. Pending: The instance is in the process of being launched or terminated.
5. Shutting-Down: The instance is in the process of being terminated.
6. Rebooting: The instance is being rebooted.
7. Stopping: The instance is being stopped.
8. shutting-down: The instance is in the process of being terminated.
9. stopped: The instance is not running, but the data on the instance’s storage volumes is still preserved. A stopped instance can be started again at any time.
10. stopping: The instance is being stopped.
11. terminated: The instance is permanently terminated, and the data on the instance’s storage volumes is also deleted.
12. shutting-down: The instance is in the process of being terminated.

Root Device Volumes

Root device volumes refer to the storage volume that contains the root file system of an Amazon Elastic Compute Cloud (EC2) instance. The root device volume is where the operating system and all of the instance’s files are stored. It is typically the first storage volume that is created when an instance is launched, and is typically an Amazon Elastic Block Store (EBS) volume or an instance store volume. The root device volume is important because it contains the necessary files for the instance to boot and function properly.

AMI

An Amazon Machine Image (AMI) is a pre-configured virtual machine image provided by Amazon Web Services (AWS) that is used to launch instances in the Elastic Compute Cloud (EC2). An AMI is a package that contains all the information required to launch a fully-functional instance, including the operating system, application server, and any additional software.

An AMI includes the following:

• Machine Image: A snapshot of the root file system that is used to launch an instance.
• Kernel: The virtualization technology that the instance uses to interact with the underlying hardware.
• Ramdisk: An optional memory disk that contains data used during the instance’s initialization process.

Users can choose from a wide variety of pre-configured AMIs that are available in the AWS Marketplace or create their own custom AMIs. This allows users to easily launch instances with a specific configuration and set of software, without having to manually install and configure the software themselves. Users can also share AMI with other AWS accounts or make it public.

Additionally, AMI’s can be created and managed using AWS Management Console, AWS Command Line Interface (CLI), or SDKs provided by AWS.

Pricing

Amazon Elastic Compute Cloud (EC2) pricing is based on a pay-as-you-go model, which means that users only pay for the resources they use. The cost of using EC2 varies depending on the type and number of instances used, as well as the amount of data transferred in and out of the instances.

There are two main types of EC2 instances: On-Demand and Reserved Instances.

1. On-Demand instances: Users pay a fixed hourly rate for each instance, and can launch as many instances as needed. This is a good option for users who need the flexibility to scale up or down as needed.
2. Reserved Instances: Users pay a lower hourly rate in exchange for committing to use the instance for a one or three-year term. This is a good option for users who need a stable and predictable level of computing resources.

Amazon Elastic Compute Cloud (EC2) Reserved Instances are a type of EC2 instance pricing option that allows users to pay a lower hourly rate in exchange for committing to use the instance for a one or three-year term.

When you purchase a Reserved Instance, you pay an upfront fee and are then charged a lower hourly rate for the usage of the instance. The upfront fee and hourly rate will depend on the type and term of the Reserved Instance. By committing to use the instance for a longer period, you can save money on your EC2 costs compared to using On-Demand instances.

Reserved Instances also come in two forms: Standard and Convertible

1. Standard Reserved Instances: With standard reserved instances, you have to commit to the instance type and availability zone. This makes it a good option for workloads that are predictable and do not change frequently.
2. Convertible Reserved Instances: With convertible reserved instances, you can change the instance type, operating system, or tenancy (if applicable) of the reserved instance. This makes it a good option for workloads that are not predictable or change frequently.

Reserved Instances can also be shared among multiple accounts within an organization through a feature called “Reserved Instance Sharing”

It is important to note that Reserved Instances do not change the performance or functionality of the instances, it only changes the billing mechanism.

Spot

Amazon Elastic Compute Cloud (EC2) Spot Instances are a type of EC2 instance pricing option that allows users to bid on spare Amazon EC2 computing capacity at a significant discount. These instances can be used for workloads that are flexible and can be interrupted, such as batch jobs, big data processing, and testing and development. Spot instances are terminated if the bid price is lower than the current Spot price, which fluctuates based on the supply and demand of spare Amazon EC2 capacity.

Spot Fleet

Amazon Elastic Compute Cloud (EC2) Spot Fleet is a service that enables you to provision a fleet of Spot instances automatically, and helps you to balance the capacity and cost of your fleet. Spot Fleet automatically increases or decreases the number of instances in the fleet based on the target capacity that you set. It also allows you to specify the instance types, Availability Zones, and purchase options that you prefer, and automatically provisions the instances that are the most cost-effective at the time of launch. Spot Fleet helps you to use Spot instances in a more efficient and flexible way, by automatically scaling the number of instances based on your needs.

Spot Capacity pool

Amazon Elastic Compute Cloud (EC2) Spot Capacity Pools is a feature that allows users to separate and prioritize their Spot instances across different pools. Each pool has its own unique set of instance types and availability zones, and also has its own unique Spot price. This allows users to prioritize their workloads and allocate capacity to the most important workloads first. Users can also create their own custom pools and assign instances to them. This feature allows users to have more control over their Spot instances and the instances that are terminated when Amazon reduces the capacity in a particular pool.

Allocation strategy for Spot Instances

When using Amazon Elastic Compute Cloud (EC2) Spot Instances, it is important to have an allocation strategy in place to optimize the use of Spot instances and minimize the impact of interruptions. Here are a few allocation strategies that can be used:

1. Lowest Price First: This strategy prioritizes the use of Spot instances with the lowest bid price, in order to maximize cost savings.
2. Diversified Allocation: This strategy uses a mix of different instance types and availability zones, to spread the workload across multiple pools and minimize the impact of interruptions.
3. Capacity Optimized: This strategy prioritizes the use of the most available Spot instances, in order to minimize interruptions and ensure a steady supply of computing resources.
4. Capacity Pool: This strategy separates and prioritizes the Spot instances across different pools, based on the workloads, to have more control over which instances are terminated when Amazon reduces the capacity in a particular pool.
5. Spot Fleet: This strategy allows you to provision a fleet of Spot instances automatically and helps you to balance the capacity and cost of your fleet, by automatically scaling the number of instances based on your needs.

Ultimately, the best allocation strategy will depend on the specific requirements of your workload and the level of interruption tolerance. It’s worth experimenting with different strategies and monitoring the results to find the best strategy

Security

Amazon Elastic Compute Cloud (EC2) provides several security features to help protect your instances and data. Here are a few examples:

1. Virtual Private Cloud (VPC): EC2 instances can be launched in a VPC, which is a virtual network that is isolated from the rest of the AWS infrastructure. This allows users to have complete control over the network configuration, including the ability to create subnets, route tables, and security groups.
2. Security Groups: A security group acts as a virtual firewall for your instances, controlling inbound and outbound traffic. It allows you to specify which IP addresses and ports are allowed to access your instances.
3. Network Access Control Lists (NACLs): A NACL is another layer of security that controls inbound and outbound traffic at the subnet level. It allows you to specify which IP addresses and ports are allowed to access your instances.
4. Key Pairs: EC2 instances can be launched with a key pair, which is used to encrypt and decrypt login credentials. This allows you to secure your instances and control access to them.
5. Identity and Access Management (IAM): IAM allows you to create users, groups, and roles, and assign permissions to them. This allows you to control who has access to your EC2 instances and what they can do with them.
6. Elastic Block Store (EBS) encryption: EBS encryption enables you to encrypt data at rest on the volumes.
7. Security Center: AWS Security Center provides a centralized view of the security status of your AWS resources and helps you to detect and respond to security threats.

It’s important to note that security is a shared responsibility between AWS and the user, and it’s the user’s responsibility to secure the instances, data, and applications running on them.

Networking

Amazon Elastic Compute Cloud (EC2) provides several networking features to help you connect and manage your instances. Here are a few examples:

1. Virtual Private Cloud (VPC): A VPC is a virtual network that is isolated from the rest of the AWS infrastructure. It allows you to create subnets, route tables, and security groups, and control the network configuration of your instances.
2. Elastic IPs: An Elastic IP is a static, public IP address that can be associated with an EC2 instance. This allows you to maintain a consistent IP address for your instances, even if they are stopped and restarted.
3. Elastic Network Interfaces (ENIs): An ENI is a virtual network interface that you can attach to an instance. This allows you to create multiple IP addresses, assign security groups, and control the network configuration of your instances.
4. Network Address Translation (NAT) Gateways: A NAT gateway allows instances in a private subnet to connect to the Internet or other AWS services, while preventing the Internet from initiating connections with the instances.
5. Elastic Load Balancing (ELB): ELB automatically distributes incoming traffic across multiple instances, ensuring high availability and performance.
6. Direct Connect: It allows you to establish a dedicated network connection from your on-premises data centers to AWS. This can provide a lower-latency and more consistent network experience than internet-based connections.
7. VPC Peering: It allows one VPC to connect with another VPC within the same region or across different regions.
8. VPC endpoint : It allows access to AWS services without requiring a NAT gateway, VPN connection, or AWS Direct Connect link.

AWS provides a rich set of tools and services for networking, allowing you to create and manage complex network configurations for your instances and applications.

Elastic Fabric Adapter (EFA)

The Elastic Fabric Adapter (EFA) is a network interface for Amazon Elastic Compute Cloud (EC2) instances that allows for high-performance communication between instances in a cluster. EFA uses the Remote Direct Memory Access (RDMA) protocol to provide low-latency, high-bandwidth communication between instances, making it well-suited for high-performance computing (HPC) and machine learning workloads. EFA is designed to be used in conjunction with the Amazon Elastic Container Service for Kubernetes (EKS) and the AWS ParallelCluster, to provide a fully-managed HPC environment. EFA allows for faster inter-node communication, and thus it can help in reducing the overall time of execution of distributed workloads.

Enhanced Networking

Enhanced Networking is a feature of Amazon Elastic Compute Cloud (EC2) instances that allows for higher performance networking capabilities. It provides higher throughput and lower latency, by enabling instances to use the Single Root I/O Virtualization (SR-IOV) technology, that allows the instances to directly access the hardware network adapters, bypassing the virtualization layer. Enhanced Networking also enables instances to use the Elastic Network Adapter (ENA) for enhanced performance and scalability.

Enhanced Networking is supported on a variety of instance types and is available for both Linux and Windows instances. It is particularly useful for workloads that require high-performance networking, such as big data processing, high-performance computing (HPC), and machine learning.

Monitoring

Monitoring in Amazon Elastic Compute Cloud (EC2) refers to the process of collecting, analyzing and interpreting data about the performance and usage of your instances. This data can be used to identify trends, diagnose issues, and take actions to improve the performance and availability of your instances.

EC2 provides several monitoring tools, such as CloudWatch, that allows you to monitor various performance metrics, such as CPU usage, memory usage, network traffic, and disk I/O. CloudWatch also allows you to set up alarms that can automatically notify you or take automated actions when certain thresholds are breached.

EC2 also provides additional monitoring features such as detailed monitoring and status check. Detailed monitoring provides data at 1-minute intervals, while basic monitoring data is available at 5-minute intervals. Status check helps ensure that your instances are running and responding as expected.

Additionally, EC2 instances can also be monitored using custom scripts, third-party monitoring tools, and by integrating with other AWS services like CloudTrail, Config, and Trusted Advisor.

Overall monitoring helps to ensure the availability and performance of your instances, and also can be used to troubleshoot issues and optimize the usage of your resources.

Instance Metadata and User Data

Instance Metadata and User Data are two features of Amazon Elastic Compute Cloud (EC2) that allow you to configure and manage your instances.

1. Instance Metadata: This is data that is automatically passed to the instance at launch and can be used to configure the instance. Examples of instance metadata include the instance’s public IP address, security groups, and IAM roles. Instance metadata can be accessed from within the instance using the EC2 metadata service (http://169.254.169.254) or by using the AWS command line interface (CLI) or SDKs.
2. User Data: This is data that you can pass to the instance at launch, such as initialization scripts or configuration files. User data can be passed to the instance as plain text or as base64 encoded text. User data can be used to automate the setup of the instance, such as installing software, configuring services, or running scripts.

Instance metadata and user data can be used together to automate the configuration of your instances and reduce the need for manual configuration. This can help to ensure that your instances are consistently configured, and can reduce the time and effort required to manage them.

Placement Groups

Placement Groups in Amazon Elastic Compute Cloud (EC2) are a way to group instances together to optimize performance and increase fault tolerance. A placement group is a logical grouping of instances within a single availability zone. By placing instances in the same placement group, you can achieve a higher level of network performance and low-latency connectivity between instances.

There are two types of placement groups:

1. Clustered Placement Group: This type of placement group is recommended for applications that require a high level of inter-instance communication, such as HPC, big data and distributed databases. This placement group provides the lowest network latency and the highest packet per second (PPS) rate.
2. Spread Placement Group: This type of placement group is recommended for applications that need to spread their instances across multiple availability zones to achieve a high fault tolerance. This placement group distributes instances evenly across multiple availability zones to help protect against the failure of a single availability zone.

It’s important to note that instances in a placement group can only be launched in the same availability zone and the same instance type. Also, once an instance is placed in a placement group, it cannot be moved to another group or availability zone.

Placement groups can be created, deleted, and modified using the AWS Management Console, AWS Command Line Interface (CLI), or SDKs provided by AWS.

Rules

Amazon Elastic Compute Cloud (EC2) has several rules that govern how instances can be launched, managed, and terminated. Here are a few examples:

1. Instance limits: There are limits on the number of instances that can be launched in a specific region and for a specific account. These limits are in place to ensure that resources are shared fairly among all EC2 customers.
2. Placement group rules: Instances in a placement group can only be launched in the same availability zone and the same instance type. Additionally, once an instance is placed in a placement group, it cannot be moved to another group or availability zone.
3. Security group rules: Security groups control inbound and outbound traffic to instances. Each instance must be associated with a security group, and rules must be defined to allow or deny specific types of traffic.
4. Elastic IP rules: Elastic IP addresses are static, public IP addresses that can be associated with instances. Each account has a limit on the number of Elastic IP addresses that can be allocated, and there may be additional charges for using more than the allocated number.
5. Auto Scaling rules: Auto Scaling groups have rules that determine when new instances should be launched or terminated based on CloudWatch alarms.
6. Tagging rules: EC2 instances and other AWS resources can be tagged with metadata, such as the environment or application the resource is associated with. Each resource has a limit on the number of tags that can be applied.
7. Elastic Block Store (EBS) rules: EBS volumes can be attached to instances, and there are rules on how

Storage

Amazon Elastic Compute Cloud (EC2) provides several storage options for instances, including:

1. Elastic Block Store (EBS): EBS is a block-level storage service that can be attached to instances. EBS volumes can be used as primary storage for data that requires frequent and granular updates. EBS also supports features like encryption, snapshots, and automatic backups.
2. Elastic File System (EFS): EFS is a file-level storage service that can be used to store shared file systems. This can be useful for scenarios such as big data processing, where multiple instances need to access the same data.
3. Instance Store: Instance store is a type of temporary storage that is physically attached to the host computer. It is often used as a cache or scratch space. Data stored in the instance store is not persistent and will be lost if the instance is terminated or the host computer fails.
4. Simple Storage Service (S3): S3 is an object-level storage service that can be used to store and retrieve files, such as images, videos, and backups. S3 can be used to store data that needs to be accessed by multiple instances or by applications running outside of EC2.
5. Glacier: Glacier is a cold storage service that can be used to store data that is infrequently accessed, such as backups or archives.
6. Storage Gateway: Storage Gateway allows you to securely store your data on-premises and in the cloud, giving you a hybrid storage solution.

EC2 instances can also be configured with multiple types of storage, depending on the needs of the application. For example, an instance can have an EBS volume for primary storage and an S3 bucket for backup storage.
