Amazon Web Services SOA-C02 Exam With Confidence Using Practice Dumps

Here are the steps to configure Amazon EventBridge to meet the above requirements:

Log in to the AWS Management Console by using the AWS Management Console shortcut from the VM desktop. Make sure that you are logged in to the desired AWS account.

Go to the EventBridge service in the us-east-2 Region.

In the EventBridge service, navigate to the "Event buses" page.

Click on the "Create event bus" button.

Give a name to your event bus, and select "default" as the event source type.

Navigate to "Rules" page and create a new rule named "RunFunction"

In the "Event pattern" section, select "Schedule" as the event source and set the schedule to run every 15 minutes.

In the "Actions" section, select "Send to Lambda" and choose the existing AWS Lambda function named "LogEventFunction"

Create another rule named "SpotWarning"

In the "Event pattern" section, select "EC2" as the event source, and filter the events on "EC2 Spot Instance interruption"

In the "Actions" section, select "Send to SNS topic" and create a new standard Amazon SNS topic named "TopicEvents"

In the "Input Transformer" section, set the Input Path to {“instance” : “$.detail.instance-id”} and Input template to “The EC2 Spot Instance has been interrupted on account.

Now all Amazon EC2 events in the default event bus will be replayable for past 90 days.

Note:

You can use the AWS Management Console, AWS CLI, or SDKs to create and manage EventBridge resources.

You can use CloudTrail event history to replay events from the past 90 days.

You can refer to the AWS EventBridge documentation for more information on how to configure and use the service:

To improve the performance of the website with long loading times, leveraging Amazon CloudFront for caching static content and implementing EC2 Auto Scaling are effective strategies.

Add Amazon CloudFront Caching:

Navigate to the CloudFront console and create a new distribution.

For the origin, specify the S3 bucket where the static content is stored.

Configure caching settings to ensure that static content is cached at edge locations for faster delivery to end users.

Update the DNS settings in Amazon Route 53 to point to the CloudFront distribution for static content.

Implement EC2 Auto Scaling:

Go to the EC2 console and create a new launch configuration or launch template for the web servers.

Set up an Auto Scaling group using the launch configuration/template.

Configure the Auto Scaling group to use health checks, and specify the desired, minimum, and maximum number of instances.

Define scaling policies to add or remove instances based on CPU utilization or other metrics.

Distribute instances across multiple Availability Zones for high availability.

Amazon EC2 Auto Scaling

To ensure that EC2 instances in private subnets can access the internet for software updates while complying with the security policy that requires instances to be in private subnets, you should use a NAT gateway. A NAT gateway allows instances in private subnets to initiate outbound traffic to the internet but prevents the internet from initiating connections to those instances.

Steps:

Create a NAT Gateway:

Open the Amazon VPC console.

In the navigation pane, choose "NAT Gateways".

Choose "Create NAT Gateway".

Select the public subnet where you want to create the NAT gateway.

Choose an Elastic IP address for the NAT gateway.

Choose "Create a NAT Gateway".

Update the Route Table for Private Subnets:

Open the Amazon VPC console.

In the navigation pane, choose "Route Tables".

Select the route table associated with your private subnets.

Choose the "Routes" tab and then "Edit routes".

Add a route with the destination 0.0.0.0/0 and the target as the NAT gateway ID.

Save the changes.

This setup ensures that instances in private subnets can access the internet via the NAT gateway in the public subnet.
