Amazon EC2 (Elastic Compute Cloud):
Virtual Servers:
Amazon EC2 provides resizable compute capacity in the cloud, allowing users to launch and manage virtual servers, known as instances, to run applications and workloads.
Instance Types:
Amazon EC2 offers a wide range of instance types optimized for different use cases and workloads, including General Purpose, Compute Optimized, Memory Optimized, Storage Optimized, and Accelerated Computing instances, enabling users to choose the right instance type based on CPU, memory, storage, and networking requirements.
Elasticity and Scalability:
Amazon EC2 enables users to scale compute capacity up or down dynamically to meet changing demand, with features like Auto Scaling for automatically adjusting the number of instances based on workload metrics, enabling high availability, fault tolerance, and cost optimization.
Operating Systems:
Amazon EC2 supports a variety of operating systems, including Amazon Linux, Ubuntu, Windows Server, Red Hat Enterprise Linux (RHEL), SUSE Linux Enterprise Server (SLES), and other popular Linux distributions and Windows editions, allowing users to choose the operating system that best suits their applications and preferences.
AMI (Amazon Machine Image):
Amazon EC2 instances are launched from AMIs, which are pre-configured templates containing the operating system, software, configuration settings, and data needed to launch an instance, enabling users to create custom AMIs or choose from a marketplace of pre-built AMIs.
Storage Options:
Amazon EC2 provides multiple storage options for instances, including EBS (Elastic Block Store) volumes for persistent block storage, instance store volumes for temporary storage, and Amazon EFS (Elastic File System) for scalable and shared file storage, allowing users to choose the right storage option based on performance, durability, and cost requirements.
Networking:
Amazon EC2 instances are deployed within virtual private clouds (VPCs), allowing users to define network settings, security groups, and access control policies to isolate instances, control inbound and outbound traffic, and connect instances to other AWS services and on-premises networks.
Security:
Amazon EC2 provides security features like IAM (Identity and Access Management) integration, security groups, network ACLs (Access Control Lists), encryption at rest and in transit, and monitoring and logging with AWS CloudTrail and Amazon CloudWatch, enabling users to secure and monitor their instances and data.
Integration and Ecosystem:
Amazon EC2 integrates seamlessly with other AWS services and third-party tools, enabling users to build, deploy, and manage applications and workloads with services like AWS Lambda, Amazon RDS, Amazon S3, AWS Batch, AWS Elastic Beanstalk, and more, as well as integration with DevOps tools for automation and CI/CD pipelines.
Use Cases:
Amazon EC2 is commonly used for a variety of use cases, including web hosting, application hosting, batch processing, data processing, gaming servers, development and testing environments, machine learning, high-performance computing (HPC), and more, enabling users to run virtually any workload in the cloud with flexibility, scalability, and reliability.
