AWS

  • AWS Access Key Rotation for IAM users: This runbook can be used to configure AWS Access Key rotation. Changing access keys (which consist of an access key ID and a secret access key) on a regular schedule is a well-known security best practice because it shortens the period an access key is active and therefore reduces the business impact if they are compromised. Having an established process that is run regularly also ensures the operational steps around key rotation are verified, so changing a key is never a scary step.

  • Add Lifecycle Policy to S3 Buckets: Attaching lifecycle policies to AWS S3 buckets enables us to automate the management of object lifecycle in your storage buckets. By configuring lifecycle policies, you can define rules that determine the actions to be taken on objects based on their age or other criteria. This includes transitioning objects to different storage classes, such as moving infrequently accessed data to lower-cost storage tiers or archiving them to Glacier, as well as setting expiration dates for objects. By attaching lifecycle policies to your S3 buckets, you can optimize storage costs by automatically moving data to the most cost-effective storage tier based on its lifecycle. Additionally, it allows you to efficiently manage data retention and comply with regulatory requirements or business policies regarding data expiration. This runbook helps us find all the buckets without any lifecycle policy and attach one to them.

  • AWS Add Mandatory tags to EC2: This xRunBook is a set of example actions that could be used to establish mandatory tagging to EC2 instances. First testing instances for compliance, and creating reports of instances that are missing the required tags. There is also and action to add tags to an instance - to help bring them into tag compliance.

  • Change AWS EBS Volume To GP3 Type: This runbook can be used to change the type of an EBS volume to GP3(General Purpose 3). GP3 type volume has a number of advantages over it's predecessors. gp3 volumes are ideal for a wide variety of applications that require high performance at low cost

  • Change AWS Route53 TTL: For a record in a hosted zone, lower TTL means that more queries arrive at the name servers because the cached values expire sooner. If you configure a higher TTL for your records, then the intermediate resolvers cache the records for longer time. As a result, there are fewer queries received by the name servers. This configuration reduces the charges corresponding to the DNS queries answered. However, higher TTL slows the propagation of record changes because the previous values are cached for longer periods. This Runbook can be used to configure a higher value of a TTL .

  • Create IAM User with policy: Create new IAM user with a security Policy. Sends confirmation to Slack.

  • Delete EBS Volume Attached to Stopped Instances: EBS (Elastic Block Storage) volumes are attached to EC2 Instances as storage devices. Unused (Unattached) EBS Volumes can keep accruing costs even when their associated EC2 instances are no longer running. These volumes need to be deleted if the instances they are attached to are no more required. This runbook helps us find such volumes and delete them.

  • Delete EBS Volume With Low Usage: This runbook can help us identify low usage Amazon Elastic Block Store (EBS) volumes and delete these volumes in order to lower the cost of your AWS bill. This is calculates using the VolumeUsage metric. It measures the percentage of the total storage space that is currently being used by an EBS volume. This metric is reported as a percentage value between 0 and 100.

  • Delete ECS Clusters with Low CPU Utilization: ECS clusters are a managed service that allows users to run Docker containers on AWS, making it easier to manage and scale containerized applications. However, running ECS clusters with low CPU utilization can result in wasted resources and unnecessary costs. AWS charges for the resources allocated to a cluster, regardless of whether they are fully utilized or not. By deleting clusters that are not being fully utilized, you can reduce the number of resources being allocated and lower the overall cost of running ECS. Furthermore, deleting unused or low-utilization clusters can also improve overall system performance by freeing up resources for other applications that require more processing power. This runbook helps us to identify such clusters and delete them.

  • Delete AWS ELBs With No Targets Or Instances: ELBs are used to distribute incoming traffic across multiple targets or instances, but if those targets or instances are no longer in use, then the ELBs may be unnecessary and can be deleted to save costs. Deleting ELBs with no targets or instances is a simple but effective way to optimize costs in your AWS environment. By identifying and removing these unused ELBs, you can reduce the number of resources you are paying for and avoid unnecessary charges. This runbook helps you identify all types of ELB's- Network, Application, Classic that don't have any target groups or instances attached to them.

  • Delete IAM profile: This runbook is the inverse of Create IAM user with profile - removes the profile, the login and then the IAM user itself..

  • Delete Old EBS Snapshots: Amazon Elastic Block Store (EBS) snapshots are created incrementally, an initial snapshot will include all the data on the disk, and subsequent snapshots will only store the blocks on the volume that have changed since the prior snapshot. Unchanged data is not stored, but referenced using the previous snapshot. This runbook helps us to find old EBS snapshots and thereby lower storage costs.

  • Delete RDS Instances with Low CPU Utilization: Deleting RDS instances with low CPU utilization is a cost optimization strategy that involves identifying RDS instances with consistently low CPU usage and deleting them to save costs. This approach helps to eliminate unnecessary costs associated with running idle database instances that are not being fully utilized. This runbook helps us to find and delete such instances.

  • Delete Unattached AWS EBS Volumes: This runbook can be used to delete all unattached EBS Volumes within an AWS region. You can delete an Amazon EBS volume that you no longer need. After deletion, its data is gone and the volume can't be attached to any instance. So before deletion, you can store a snapshot of the volume, which you can use to re-create the volume later.

  • Delete Unused AWS Secrets: This runbook can be used to delete unused secrets in AWS.

  • Delete Unused AWS Log Streams: Cloudwatch will retain empty Log Streams after the data retention time period. Those log streams should be deleted in order to save costs. This runbook can find unused log streams over a threshold number of days and help you delete them.

  • Delete Unused NAT Gateways: This runbook search for all unused NAT gateways from all the region and delete those gateways.

  • Delete Unused Route53 HealthChecks: When we associate healthchecks with an endpoint, Amazon Route53 sends health check requests to the endpoint IP address. These health checks validate that the endpoint IP addresses are operating as intended. There may be multiple reasons that healtchecks are lying usused for example- health check was mistakenly configured against your application by another customer, health check was configured from your account for testing purposes but wasn't deleted when testing was complete, health check was based on domain names and hence requests were sent due to DNS caching, Elastic Load Balancing service updated its public IP addresses due to scaling, and the IP addresses were reassigned to your load balancer, and many more. This runbook finds such healthchecks and deletes them to save AWS costs.

  • AWS Detach EC2 Instance from ASG: This runbook can be used to detach an instance from Auto Scaling Group. You can remove (detach) an instance that is in the InService state from an Auto Scaling group. After the instance is detached, you can manage it independently from the rest of the Auto Scaling group. By detaching an instance, you can move an instance out of one Auto Scaling group and attach it to a different group. For more information, see Attach EC2 instances to your Auto Scaling group.

  • AWS EC2 Disk Cleanup: This runbook locates large files in an EC2 instance and backs them up into a given S3 bucket. Afterwards, it deletes the files backed up and send a message on a specified Slack channel. It uses SSH and linux commands to perform the functions it needs.

  • Enforce HTTP Redirection across all AWS ALB instances: This runbook can be used to enforce HTTP redirection across all AWS ALBs. Web encryption protocols like SSL and TLS have been around for nearly three decades. By securing web data in transit, these security measures ensure that third parties can’t simply intercept unencrypted data and cause harm. HTTPS uses the underlying SSL/TLS technology and is the standard way to communicate web data in an encrypted and authenticated manner instead of using insecure HTTP protocol. In this runbook, we implement the industry best practice of redirecting all unencrypted HTTP data to the secure HTTPS protocol.

  • AWS Ensure Redshift Clusters have Paused Resume Enabled: This runbook finds redshift clusters that don't have pause resume enabled and schedules the pause resume for the cluster.

  • AWS Get unhealthy EC2 instances from ELB: This runbook can be used to list unhealthy EC2 instance from an ELB.
