AWS EC 2 CONSOLE

EC 2 SECURITY GROUPS § A security group acts as a virtual firewall that controls the traffic for one or more instances. § When you launch an instance, you associate one or more security groups with the instance. § You add rules to each security group that allow traffic to or from its associated instances. § All the rules from all the security groups that are associated with the instance will be evaluated to decide whether to allow traffic to reach an instance.

EC 2 KEY PAIRS –PEM FILE § Only one opportunity § Make a copy § Make another offline copy § Cannot be retrieved or restored

PEM FILE § PEM is an abbreviation for Privacy Enhanced Mail (RFC 1421 - RFC 1424) § An early standard for securing electronic mail (IRTF, IETF). § The PEM format often is used for representing a certificate, certificate request.

EC 2 – LAUNCH INSTANCE

AMI § Amazon Machine Image (AMI) § Provide information required to launch an instance, a virtual server in the cloud § Specify an AMI when launch an instance § Can launch many instances from the AMI as needed

AMI REQUIREMENTS § A template for the root volume for the instance (operating system, application server, applications) § Launch permissions that control which AWS accounts can use the AMI to launch instances. § Block device mapping that specifies the volumes to attach to the instances

HOW TO USE AN AMI § Create and register an AMI § Launch new instances § After launching instance from an AMI, deregister the AMI

AMAZON ELASTIC BLOCK STORE (EBS) § Persistent block level storage volumes for use with Amazon EC 2 instances. § Each Amazon EBS volume is automatically replicated within its Availability Zone to protect you from component failure, offering high availability and durability. § Amazon EBS volumes offer the consistent and lowlatency performance needed to run your workloads.

CREATING YOUR OWN AMI § The root storage device of the instance determines the process to create an AMI. § The root volume of an instance is either an Amazon EBS volume or an instance store volume.

TYPE OF AMI § Amazon Linux AMI § Red Hat Enterprise Linux 7. 0 § Su. SE Linux Enterprise Server 11 SP 3 § Ubuntu Server 14. 04 LTS, SSD Volume Type § Microsoft Windows Server 2012 R 2 Base § Microsoft Windows Server 2012 with SQL server Web § Microsoft Windows Server 2012 R 2 with SQL server Standard §. . .

AMAZON LINUX AMI § Amazon Linux AMI is a supported and maintained Linux image provided by AWS. § Stable, secure, high-performance execution environment for applications running on Amazon EC 2 § An Amazon EBS-based, PV-GRUB AMI that includes: § Linux 3. 4 § AWS tools § Repository access to multiple version of My. SQL, Postgre. SQL, Python, Ruby, and Tomcat

EC 2 ELASTIC IP § An Elastic IP address (EIP) is a static IP address designed for dynamic cloud computing. § With an EIP, you can mask the failure of an instance by rapidly remapping the address to another instance in your account. § Your EIP is associated with your AWS account (not a particular instance).

EC 2 SNAPSHOTS § You can periodically create a snapshot of an Amazon EBS volume to use as a baseline (for new volumes or for data backup) § Snapshots are saved incrementally § You need to retain only the most recent snapshot in order to restore the volume. § Snapshots occur asynchronously and the status of the snapshot is pending until the snapshot is complete.

AMAZON VIRTUAL PRIVATE CLOUD (VPC) § A VPC is a virtual network dedicated to your AWS account. § It is logically isolated from other virtual networks in the AWS cloud. § You can launch your AWS resources, such as Amazon EC 2 instances, into your VPC. § You can configure your VPC, set its IP address range, security settings, etc.
