ANSWER:-
a):- Yes, I have golden image for web and application servers because the three of the benefits of using a golden image such as Save time, Reduce error,Consitency. Golden image is a template for a virtual machine , virtual desktop, server or hard disk drive. Golden image may referred a clone image, master image and base image.
b):- Yes, I have replace existing third-party load balancer with ELB services because Elastic Load Balancing is automatically distributes incoming application across multiple targets, such as Amazon EC2 instances, IP addresses, and Lambda functions. It can be handling various load of application traffic in a single Availability Zone multiple Availability Zones. Elastic Load Balancing have all feature the high availability, automatic scaling, necessary to make your applications
c):- Yes, application is hosted in public subnet. public subnet with a size /24 IPv4 cidr block. This is provides 256 private IPv4 addresses. public subnet is a subnet that's associated with a route table that has route to an Internet gateway. instances in the public subnet send outbound traffic directly to Internet, whereas the instances in the private subnet can not.
d):-Use of CloudTrail API to view and track API calls made to account using: Event history in the CloudTrail and CloudWatch Logs.All services have logs recorded and available with CloudTrail.View all supported services and integrations and event types such as create, modify, delete from the 90days. CloudWatch Logs, can search operations that change the state of a resource, such as StopInstances.
e):- CloudWatch is help to monitor on premise servers with the installation of the CloudWatch agent .Downloaded the CloudWatch agent on computer and created the agent of the file , you can use that configuration file to install agent on other on-premises servers.
f):- configurations launch is help to plan auto scaling deployments.the launch configuration is an instance configuration template that an Auto Scaling group uses to launch EC2 instances. you create a Launch configuration, you can specify information for instances.
g):- You want to use billing alarm alert for linked accounts if the developers or projects in your organization are responsible for managing their own budgets or reducing costs. You can set up your first billing alarm alert for a linked account in minutes.
h):- Lambda function is help to be created automate solution with cloudwatch alerts. Aws Cloud Formation template to creates all required resources for setting up Lambda functions for creation and deletion of CloudWatch alarms. the two Lambda functions use one for creating CloudWatch alarms for ec2 instances and one for stopping CloudWatch alarms for ec2 instances.used of the Lambda functions to communicate with services such as Amazon sns and Systems Manager.
i):- step scaling policies is help improving application.choose scaling metrics for the CloudWatch alarms that trigger the scaling process to define how your scalable target should be scaled when a threshold is in for a specified number of evaluation periods.If scaling metric is a metric that increases or decreases proportionally to the capacity of the scalable target.Application Auto Scaling supports types for step scaling policies such as Change In Capacity,Exact Capacity,Percent Change In Capacity.
j):- step scaling policies is help to save the more money. In step scalling the billing alarm are use to help the developer for managing own budgets and reducing cost and improve the performance.
