"A certificate is eligible for automatic renewal subject to the following considerations: ELIGIBLE if associated with another AWS service, such as Elastic Load Balancing or CloudFront. ELIGIBLE if exported since being issued or last renewed. ELIGIBLE if it is a private certificate issued by calling the ACM RequestCertificate API and then exported or associated with another AWS service. ELIGIBLE if it is a private certificate issued through the management console and then exported or associated with another AWS service." https://docs.aws.amazon.com/acm/latest/userguide/managed-renewal.html

Amazon FSx for Windows File Server provides a fully managed native Microsoft Windows file system that supports the SMB protocol and Windows ACLs, ensuring compatibility with existing applications and processes. Using a Multi-AZ deployment ensures high availability by providing automatic failover to a standby instance in a different Availability Zone.

Create Amazon FSx for Windows File Server:

Open the Amazon FSx console at Amazon FSx Console.

Choose Create file system.

Select Amazon FSx for Windows File Server, then click Next.

Configure File System Settings:

In the File system details section, provide the necessary details such as Deployment type, Storage capacity, and Throughput capacity.

Select Multi-AZ deployment to ensure high availability.

Choose the Windows authentication method, either AWS Managed Microsoft AD or Self-managed Microsoft AD.

Network & Security Configuration:

Select the VPC, subnet, and security groups to attach to the file system.

Ensure subnets are in different Availability Zones for Multi-AZ configuration.

Review and Create:

Review the settings and click Create file system.

Access the File System:

Once the file system is created, you can map the network drive using the provided DNS name and manage permissions using Windows ACLs.

Creating a Multi-AZ File System

To monitor and remediate open SSH ports, AWS Config and Systems Manager Automation are ideal:

AWS Config Rule: Use AWS Config to monitor security groups and detect when SSH (port 22) is open to the public. Config rules can be set up to trigger remediation actions automatically.

Systems Manager Automation Runbook: Create or use a predefined automation runbook that can remove the open SSH rule from security groups, thus closing port 22 to the public.

CloudWatch alarms are not ideal for monitoring security group configurations. Amazon Inspector focuses on vulnerability assessment rather than continuous monitoring for specific port access.

Using an RDS read replica will improve the performance and availability of the RDS instance by offloading read queries to the replica. This will also ensure that the reporting job completes in a timely manner and does not affect the performance of other queries that might be running on the RDS instance. Additionally, updating the reporting job to query the reader endpoint will ensure that all read queries are directed to the read replica.

To automate the initialization of additional EBS volumes on Windows EC2 instances, the most effective approach is to integrate initialization scripts within the instance so that they execute upon startup:

Configure Initialization Script: Use a Windows PowerShell script (InitializeDisks.ps1) to initialize and format the additional EBS volumes. The script can assign drive letters based on configurations specified in DriveLetterMappingConfig.json.

Automate at Launch: Ensure that the PowerShell script runs automatically upon instance startup. This can be configured through Windows Task Scheduler or by setting it up in the startup folder.

Create a Custom AMI: Once the instance is configured with the script and successfully initializes the disks on startup, create a new AMI from this setup. This AMI can then be used to launch new instances that will automatically initialize their additional EBS volumes with no manual intervention required.

This method leverages native Windows tools and AWS capabilities to automate EBS volume initialization, enhancing operational efficiency without additional external dependencies.

To send local logs from a fleet of servers to Amazon CloudWatch:

Install the Unified CloudWatch Agent: The unified CloudWatch agent is capable of collecting both logs and metrics from servers. This agent supports various operating systems and can be configured according to specific logging requirements.

Configuration of the Agent: The agent's configuration involves specifying which log files to monitor and how they should be processed. This configuration can be done manually or through the AWS Systems Manager for automated deployment across multiple servers.

Send Logs to CloudWatch: Once configured and running, the CloudWatch agent will continuously monitor the specified log files and send the log data to Amazon CloudWatch Logs, allowing you to view, search, and set alarms on log data.

This setup ensures a robust and scalable way to manage log data across a fleet of servers, leveraging AWS native services for seamless integration and management.

To efficiently manage application deployments and updates on Amazon EC2 instances within an Auto Scaling group, along with ensuring security through vulnerability scans:

EC2 Image Builder: This AWS service automates the creation, management, and deployment of customized, secure, and up-to-date "golden" server images. By using EC2 Image Builder, you can automate the installation of software, patches, and security configurations.

Custom Recipes: Define a custom recipe in EC2 Image Builder that includes steps to install the application and its dependencies. Additionally, configure the recipe to perform vulnerability scans as part of the image creation process.

Automated Pipeline: Set up an Image Builder pipeline that triggers on a regular schedule (e.g., weekly) to incorporate the latest application updates and security patches into the AMI. The new AMIs can then be automatically used by the Auto Scaling group to launch updated and secure instances.

This solution not only streamlines the management of application deployments and updates but also ensures that all instances launched by the Auto Scaling group meet the latest security and compliance standards, minimizing operational overhead and enhancing security.

To monitor and receive alerts when the EC2 instance service quota usage reaches 70% or more:

Service Quotas Console: Navigate to the Service Quotas console within AWS and identify the specific quota for EC2 instances.

Create a CloudWatch Alarm: Directly from the Service Quotas console, set up a CloudWatch alarm for the EC2 instance quota metric. Configure the alarm to trigger when the quota utilization reaches or exceeds 70%.

Notification Setup: Link this alarm to an Amazon SNS topic that will send a notification to relevant stakeholders or systems when the quota usage threshold is breached.

This method provides an automated, straightforward way to monitor resource limits and ensures that stakeholders are promptly notified, enabling them to take proactive measures to manage the quota and prevent service disruption.
