- 5. Amazon EC2 Introduction • “AnEC2 instance is a virtual server in Amazon's Elastic Compute Cloud (EC2) that run applications on the Amazon Web Services (AWS) infrastructure.” Each EC2 instance may have all or some of below settings applied: • Processor • Memory • EBS Volume • One or more EIPs • IAM Role • Security Groups • SSH Keys
- 6. Amazon EC2 Features • EC2based compute machines are known as instances • Instances are provisioned from preconfigured templates known as Amazon Machine Images (AMI) • Instances are categorized based on processor capacity, memory, storage, and networking, known instance types. • Secure login to the instances is achieved by using key pairs or recently added AWS Session Manager.
- 7. Amazon EC2 Features • Diskstorage volumes achieved using Amazon Elastic Block Storage (EBS) • Limited access through Security Groups • Risk of data loss if Instance store volumes are used • Metadata, known as tags, that can be create and assign to Amazon EC2 resources • Common actions i.e. start/stop, security scans etc can be performed in bulk using Tags
- 8. Amazon EC2 Benefits • Elasticityenables to increase or decrease capacity within minutes • User have complete control of the instances including root access and the ability to interact • Wide choice of multiple instance types, operating systems, and software packages available • Offers a highly reliable environment where replacement instances can be rapidly and predictably commissioned • Fully manageable through AWS Management Console, the AWS Command Line Tools (CLI), or AWS SDKs.
- 9. Amazon EC2 EC2 ElasticIP Addresses • An Elastic IP address is a static IPv4 address designed for dynamic cloud computing • An Elastic IP address is associated with AWS account • With an Elastic IP address, User can mask the failure of an instance or software by rapidly remapping the address to another instance • EIP have fix mac address hence useful for tracking • Recently Amazon allowed to bring custom IP addresses to cloud NOTE: AWS currently do not support Elastic IP addresses for IPv6.
- 10. Amazon EC2 EC2 InstancesTypes • General purpose • Compute optimized • Memory optimized • Accelerated Computing • Storage optimized https://aws.amazon.com/ec2/instance-types/
- 11. Amazon EC2 Amazon MachineImage (AMI) • An Amazon Machine Image (AMI) provides the information required to launch an instance, which is a virtual server in the cloud. You must specify a source AMI when you launch an instance An AMI includes the following: 1. A template for the root volume for the instance (for example, an operating system, an application server, and applications) 2. Launch permissions that control which AWS accounts can use the AMI to launch instances 3. A block device mapping that specifies the volumes to attach to the instance when it's launched
- 12. Amazon Machine Image(AMI) • Common AMIs • Amazon Linux • RedHat Enterprise Linux • Suse Linux Enterprise • Ubuntu Server 18 • Windows Server 2019 • Deep Learning AMIs • Windows Server with SQL Server Instance Instances AMI Image Create AMI Create Multiple Instances • Marketplace AMIs • OpenVPN • Trendmicro • Juniper • Barracuda cloudgen Firewall • etc
- 13. Amazon EC2 Amazon ElasticBlock Store (EBS) • EBS provides persistent, highly available, consistent, low-latency block storage volumes for use with Amazon EC2 instances • Each Amazon EBS volume is automatically replicated within its Availability Zone to protect you from component failure, offering high availability and durability. • It is designed for an application managers who need to tune workloads for capacity, performance and cost • EBS are available in: • General purpose SSD (gp2) • Provisioned IOPS (io2) • Throughput optimized HDD (st1) • Cold HHD (sc1) • Magnetic (Previous generation)
- 14. Amazon EC2 • EBSFeatures • Whether its SSD-backed or HDD-backed volumes, EBS deliver High Performance Volumes that needed the most demanding applications • EBS volume is designed for 99.999% Availability • EBS Encryption provides seamless support for data-at-rest and data-in-transit between EC2 instances and EBS volumes • Protect the data by creating point-in-time Snapshots of EBS volumes • Dynamically increase capacity, tune performance, and change the type of live EBS volumes • Once a VM is destroyed, the EBS are sent to SCRUB pool before they are made available again to the customers
- 15. Amazon EC2 • AmazonEBS Instances EBS 6 GB Root Volume / dev / sda1
- 16. Amazon EC2 EC2SecurityGroups • Asecurity group acts as a virtual firewall that controls the traffic for one or more instances • When instance has launched, it associate with one or more security groups • User can add rules to each security group that allow traffic to or from its associated instances • User can modify the rules for a security group at any time • Applied to all instances that are associated with the security group running in any AZ • Security Groups are stateful. If an incoming rule is allowed, it will open outgoing automatically
- 17. Amazon EC2 • AmazonEC2 Pricing • Amazon EC2 is free to try. There are four ways to pay for Amazon EC2 instances: • With On-Demand instances, user can pay for compute capacity by per hour or per second depending on which instances you run. No longer-term commitments or upfront payments are needed. On-Demand • Amazon EC2 Spot instances allow user to request spare Amazon EC2 computing capacity for up to 90% off the On-Demand price. Spot Instances
- 18. Amazon EC2 • AmazonEC2 Pricing • Reserved Instances provides a significant discount (up to 75%) compared to On-Demand instance pricing. Reserved Instances • A Dedicated Host is a physical EC2 server dedicated for use. Dedicated Hosts can helps to reduce costs by allowing user to use existing server-bound software licenses, including Windows Server, SQL Server, and SUSE Linux Enterprise Server. Dedicated Hosts
- 19. Amazon EC2 • Withper-second billing, pay for only what is in use. It takes cost of unused minutes and seconds in an hour off of the bill. • EC2 usage are billed on one second increments, with a minimum of 60 seconds. Similarly, provisioned storage for EBS volumes will be billed per-second increments, with a 60 second minimum. Per Second Billing • Amazon EC2 Pricing
