When your primary instance fails, a replica can be promoted to a primary instance. Identify and remove old AWS Elastic Block Store (EBS) volume snapshots for cost optimization. Checks your usage of ElastiCache and provides recommendations on purchase of Reserved Nodes to help reduce costs incurred from using ElastiCache On-Demand. Note: This check does not guarantee the identification of exposed access keys or compromised EC2 instances. Recommendations are only available for the Paying Account. Recommended configuration for any security group rule is to allow access from specific Amazon Elastic Compute Cloud (Amazon EC2) security groups or from a specific IP address. Note: This check displays information for EC2 instances in the following Regions: N. Virginia (us-east-1), N. California (us-west-1), Oregon (us-west-2), Ireland (eu-west-1), Sao Paolo (sa-east-1), Tokyo (ap-northeast-1), Singapore (ap-southeast-1), and Sydney (ap-southeast-2). Checks for Amazon Route 53 hosted zones for which your domain registrar or DNS is not using the correct Route 53 name servers. Recommendations are only available for the Paying Account. When Amazon Route 53 health checks determine that the primary resource is unhealthy, Amazon Route 53 responds to queries with a secondary, backup resource record set. Enable Encryption by Default for EBS Volumes. © 2021, Amazon Web Services, Inc. or its affiliates. Ensure that your new Amazon EBS volumes are … Otherwise, you begin by setting up the CloudWatch event rule in the primary region for the createSnapshot event and also the CloudWatch event rule in the DR region for the copySnapshot command. For example, many customers run automated start/stop scripts that turn off … Actual savings will vary if you are using Reserved Instances or Spot Instances, or if the instance is not running for a full day. Checks the root account and warns if multi-factor authentication (MFA) is not enabled. Checks the availability of resources associated with launch configurations and your Auto Scaling groups. This check covers recommendations based on partial upfront payment option with 1-year or 3-year commitment. AWS - Best Practices for Deploying Amazon WorkSpaces July 2016 Page 4 of 45 Abstract This whitepaper outlines a set of best practices for the deployment of Amazon WorkSpaces. Reserved Instances do not renew automatically; you can continue using an EC2 instance covered by the reservation without interruption, but you will be charged On-Demand rates. All rights reserved. An AWS snapshot is just a point-in-time copy of an Amazon EBS volume with limited storage and recovery options. You can also choose to require multi-factor authentication (MFA) for any object deletions or configuration changes to your buckets. Improve the security of your application by closing gaps, enabling various AWS security features, and examining your permissions. If you have intentionally configured your security groups in this manner, we recommend using additional security measures to secure your infrastructure (such as IP tables). Checks for Amazon EBS volumes whose performance might be affected by the maximum throughput capability of the Amazon EC2 instance they are attached to. To jump straight to testing the workflow, see the “Testing in your Account” section. Checks for resource record sets that are associated with health checks that have been deleted. New versions of predefined policies are released as new configurations become available. From there, you can see the execution of the state machine. A VPN should have two tunnels configured at all times to provide redundancy in case of outage or planned maintenance of the devices at the AWS endpoint. Note: this check displays information for EC2 instances in the following Regions: N. Virginia (us-east-1), N. California (us-west-1), Oregon (us-west-2), Ireland (eu-west-1), Sao Paolo (sa-east-1), Tokyo (ap-northeast-1), Singapore (ap-southeast-1), and Sydney (ap-southeast-2). An SPF (sender policy framework) record publishes a list of servers that are authorized to send email for your domain, which helps reduce spam by detecting and stopping email address spoofing. Choose Actions, Create Snapshot, and then create a snapshot. If a security group has a large number of rules, performance can be degraded. We then simulate every combination of reservations in the generated category of usage in order to identify the best number of each type of Reserved Instance to purchase to maximize your savings. We then simulate every combination of reservations in the generated category of usage in order to identify the best number of each type of RI to purchase to maximize your savings. A load balancer that is configured accrues charges, so this is a cost-optimization check as well. To get daily CPU utilization data, download the report for this check. Checks AWS NVMe driver version for EC2 Windows instances, and then alerts you if the driver (a) is deprecated and no longer supported; (b) is deprecated with identified issues; or (c) has an available upgrade. When you use alias resource record sets, Route 53 routes your DNS queries to AWS resources free of charge. Then, determine how many snapshots you currently have for a particular EBS volume and assess that value against a retention rule. Password content requirements increase the overall security of your AWS environment by enforcing the creation of strong user passwords. I'm planning on scheduling a cron job in EC2 to run the backup. Recommendations are only available for the Paying Account. Checks for your use of AWS CloudTrail. CloudWatch Events integrates with AWS Lambda to let you execute your custom code when one of those events occurs. CloudTrail provides increased visibility into activity in your AWS account by recording information about AWS API calls made on the account. Checks for load balancers configured with a missing security group or a security group that allows access to ports that are not configured for the load balancer. For consistently higher IOPS, you can use a Provisioned IOPS (SSD) volume. Checks buckets in Amazon Simple Storage Service (Amazon S3) that have open access permissions. This check examines explicit bucket permissions and associated bucket policies that might override the bucket permissions. Choose the Launch Stack buttons below to launch the primary and DR region stacks in Dublin and Ohio, respectively. The state machine then tags the snapshot, cleans up the oldest snapshots if the number of snapshots is greater than the defined number to retain, and copies the snapshot to a DR region. Amazon Web Services – Tagging Best Practices Page 2 specific versions of resources to archive, update, or delete. Identify EC2 Instances with Low Utilization. This check covers recommendations based on partial upfront payment option with 1-year or 3-year commitment. Your completed rule should look like in the following: As in the primary region, choose Configure Details and then give this rule a name and description. This architecture covers the pieces of the workflow that need to happen after a snapshot has been created. If your access key is exposed, take immediate action to secure your account. Relying on snapshots in lieu of backups is a rather … It does not include other ELB types (Application Load Balancer, Network Load Balancer). When you use a secure protocol for a front-end connection (client to load balancer), the requests are encrypted between your clients and the load balancer, which is more secure. Unrestricted access increases opportunities for malicious activity (hacking, denial-of-service attacks, loss of data). AWS Best Practices: use the Trusted Advisor. Checks your usage of RedShift and provides recommendations on purchase of Reserved Nodes to help reduce costs incurred from using RedShift On-Demand. A misconfigured certificate is a certificate that’s expiring within next 7 days, that’s already expired, or that’s using an SHA1 weak-signature algorithm. Checks the age of the snapshots for your Amazon Elastic Block Store (Amazon EBS) volumes (available or in-use). You may also want to have retry logic or exception handling for each step. As it … The following is an architecture diagram of the reference architecture: First, pull the code from GitHub and use the AWS CLI to create S3 buckets for the Lambda code in the primary and DR regions. Some of the best practices recommended for hosting NoSQL databases on Amazon EC2 are: Multiple Deployment Options. Recommendations are only available for the Paying Account. An Amazon RDS performance best practice is to allocate enough RAM so that your working set resides almost completely in memory. AWS Trusted Advisor offers a rich set of best practice checks and recommendations across five categories: cost optimization, security, fault tolerance, performance, and service limits. Checks for Amazon EC2 Reserved Instances that are scheduled to expire within the next 30 days or have expired in the preceding 30 days. Step Functions integrates with Lambda to provide a mechanism for building complex serverless applications. This check is not available to accounts linked in Consolidated Billing. By default, backups are enabled with a retention period of 1 day. When you specify a long TTL, DNS resolvers take longer to request updated DNS records, which can cause unnecessary delay in rerouting traffic (for example, when DNS Failover detects and responds to a failure of one of your endpoints). To allow Amazon Route 53 to route queries to the region with the lowest network latency, you should create latency resource record sets for a particular domain name (such as example.com) in different regions. But how do you automate something like this in AWS? Checks the permission settings for your Amazon Relational Database Service (Amazon RDS) DB snapshots and alerts you if any snapshots are marked as public. Aside from third-party solutions, snapshots are the best option for backing up your EC2 virtual machines, says … Examines the health check configuration for Auto Scaling groups. The state machine then tags the s… Click here to return to Amazon Web Services homepage, set up CloudWatch Events to create the snapshots on a schedule. It enables you to build event-driven IT automation, based on events happening within your AWS infrastructure. If a security group allows access to ports that are not configured for the load balancer, the risk of loss of data or malicious attacks increases. Checks popular code repositories for access keys that have been exposed to the public and for irregular Amazon Elastic Compute Cloud (Amazon EC2) usage that could be the result of a compromised access key. To meet these requirements, customers copy their EBS snapshots to the DR region. If a load balancer has no associated back-end instances or if network traffic is severely limited, the load balancer is not being used effectively. Now, set up the CloudWatch Events rule in the DR region as well. In a different environment, I used the mysql backup tools to simply dump the DB to a sql file but the EBS snapshot system seems like a better solution. Any errors that are caught during execution result in the execution of a Lambda function that writes a message to an SNS topic. Checks the EC2Config service for Amazon EC2 Windows instances and alerts you if the EC2Config agent is out of date or configured incorrectly. As an AWS customer, you might define recovery point objectives (RPO) and recovery time objectives (RTO) for different tier applications in your business. Amazon EBS snapshots. Understand the implications of the root device type for data persistence, backup, and recovery. These recommendations should be considered an alternative to your RI recommendations and choosing to act fully on both sets of recommendations would likely lead to over commitment. Consistent high utilization can indicate optimized, steady performance, but it can also indicate that an application does not have enough resources. Best Practices for Managing Your EC2 Snapshots on AWS Cloud. The possibilities are endless: Happy coding and please let me know what useful state machines you build! When you make a snapshot public, you give all AWS accounts and users access to all the data on the snapshot. Using the latest version of EC2Config enables and optimizes endpoint software management such as PV driver checks to stay up-to-date with the most secure and reliable endpoint software. AWS regularly upgrades existing AMIs which further point to snapshots, permissions and boot volumes to use when an instance comes up. Examples of these workflows are: setting up permissions policies, creating encrypted EBS volumes, running Amazon EC2 instances, taking snapshots… If you’re using a custom built AMI, it’s always a good practice … An access key consists of an access key ID and the corresponding secret access key. We then simulate every combination of reservations in the generated category of usage in order to identify the best number of each type of Reserved Instance to purchase to maximize your savings. See how you can save money on AWS by eliminating unused and idle resources or making commitments to reserved capacity. These are sourced from AWS Cost Explorer which can be used to get more detailed recommendation information, or to purchase a savings plan. For Event Source, choose Event Pattern and specify the following values: For Target, choose Step Functions state machine, then choose the state machine created by the CloudFormation commands. Checks your usage of EC2, Fargate, and Lambda over the last 30 days and provides Savings Plan purchase recommendations, which allows you to commit to a consistent usage amount measured in $/hour for a one or three year term in exchange for discounted rates. VPN tunnel redundancy. For increased security, we recommend that you protect your account by using MFA, which requires a user to enter a unique authentication code from their MFA hardware or virtual device when interacting with the AWS console and associated websites. This reference architecture is just an example of how you can use Step Functions and CloudWatch Events to build event-driven IT automation. Note: Data for EC2 On-Demand instance limits is available only for these AWS Regions: Asia Pacific (Tokyo) [ap-northeast-1], Asia Pacific (Singapore) [ap-southeast-1], Asia Pacific (Sydney) [ap-southeast-2], EU (Ireland) [eu-west-1], South America (São Paulo) [sa-east-1], US East (N. Virginia) [us-east-1], US West (N. California) [us-west-1], US West (Oregon) [us-west-2]. Checks the configuration of your Amazon Relational Database Service (Amazon RDS) for any DB instances that appear to be idle. You can view these executions by going to the Step Functions console and selecting your state machine. Checks CloudFront distributions for alternate domain names with incorrectly configured DNS settings. Checks for regions that have only one AWS Direct Connect connection. Unlike traditional static IP addresses, EIPs can mask the failure of an instance or Availability Zone by remapping a public IP address to another instance in your account. It's best practice for all the DB instances in a cluster to have the same accessibility. Checks for automated backups of Amazon RDS DB instances. Watch this 30-minute technical webinar from Veeam’s AWS experts and receive: - AWS backup best practices … Checks the Amazon Elastic Compute Cloud (Amazon EC2) instances that were running at any time during the last 14 days and alerts you if the daily CPU utilization was 10% or less and network I/O was 5 MB or less on 4 or more days. Bucket permissions that grant Upload/Delete access to everyone create potential security vulnerabilities by allowing anyone to add, modify, or remove items in a bucket. Certificates that are encrypted by using the SHA-1 hashing algorithm are being deprecated by web browsers such as Chrome and Firefox. Amazon Web Services currently offers … Checks for cases where an Amazon Aurora DB cluster has both private and public instances. Some customers also have policies stating that backups need to be stored a certain number of miles away as part of a disaster recovery (DR) plan. AWS recommends using a secure protocol (HTTPS or SSL), up-to-date security policies, and ciphers and protocols that are secure. In cases where you have reached this regional limit, you might be unable to launch new on-demand instances even though Trusted Advisor will indicate that you have not reached any of your per-instance type limits within that region. The new state machine has a similar flow and uses some of the same Lambda code to clean up the oldest snapshots that are greater than the defined number to retain. © 2021, Amazon Web Services, Inc. or its affiliates. Business continuity is important for building mission-critical workloads on AWS. When connection draining is not enabled and you remove (deregister) an Amazon EC2 instance from a load balancer, the load balancer stops routing traffic to that instance and closes the connection. When you configure Amazon CloudFront to deliver your content, requests for your content are automatically routed to the nearest edge location where content is cached, so it can be delivered to your users with the best possible performance. New Reserved Instances can have the same parameters as the expired ones, or you can purchase Reserved Instances with different parameters. If a volume remains unattached or has very low write activity (excluding boot volumes) for a period of time, the volume is probably not being used. AWS snapshots come in the form of Amazon Elastic Block Storage snapshots.. How do you do it without servers? Some headers, such as Date or User-Agent, significantly reduce the cache hit ratio (the proportion of requests that are served from a CloudFront edge cache). This allows you to have event-driven snapshot management based on snapshot completion events firing in CloudWatch Event rules. Checks for load balancers that do not have cross-zone load balancing enabled. Checks the logging configuration of Amazon Simple Storage Service (Amazon S3) buckets. In this post, I discuss how you can target Step Functions in a CloudWatch Events rule. Cross-zone load balancing distributes requests evenly across all back-end instances, regardless of the Availability Zone the instances are in. Although some scenarios can result in low utilization by design, you can often lower your costs by managing the number and size of your instances. This does not make your account secure; it only partially limits the unauthorized usage for which you could be charged. Your completed rule should look like the following: Choose Configure Details and give the rule a name and description. To additionally protect your account from excessive charges, AWS temporarily limits your ability to create some AWS resources. If an Amazon Redshift cluster has not had a connection for a prolonged period of time or is using a low amount of CPU, you can use lower-cost options such as downsizing the cluster or shutting down the cluster and taking a final snapshot. Also, both state machines demonstrate how you can use Step Functions to handle errors within your workflow. And, following best practices, you take snapshots of your EBS volumes to back up the data on Amazon S3, which provides 11 9’s of durability. This check is not available to accounts linked in Consolidated Billing. First, open the CloudWatch console in the primary region. For bursty IOPS, you can use a General Purpose (SSD) volume. This check covers recommendations based on Standard Reserved Instances with partial upfront payment option. The working set is the data and indexes that are … Auto Scaling groups and launch configurations that point to unavailable resources do not operate as intended. In this post we’ll take a closer look at the anatomy of these AWS snapshots and their key use cases, first by giving an overview of storage snapshots … You must create correctly configured primary and secondary resource record sets for failover to work. For more information on this recommendation, see Reserved Instance Optimization Check Questions in the Trusted Advisor FAQs. Therefore, if any errors occur, you can subscribe to the SNS topic and get notified. Checks the password policy for your account and warns when a password policy is not enabled, or if password content requirements have not been enabled. Some information described in this book may not seem like the best practices. Availability Zones are distinct locations that are designed to be insulated from failures in other Availability Zones and to provide inexpensive, low-latency network connectivity to other Availability Zones in the same region. AWS Config is a service that maintains a configuration history of your AWS resources and evaluates the configuration against best practices and your internal policies. During planned database maintenance or the failure of a DB instance or Availability Zone, Amazon RDS automatically fails over to the standby so that database operations can resume quickly without administrative intervention. Estimated monthly savings are calculated by using the current usage rate for On-Demand Instances and the estimated number of days the instance might be underutilized. This check currently only checks for Classic Load Balancer type within ELB service. I know this, and to help reader to separate what are established best practices and what is just another opinionated way of doing things, I sometimes use hints to provide some context and icons to specify the level of maturity on each subsection related to best practices. Move infrequently-accessed data to lower cost tiers. Because CloudTrail delivers log files to an Amazon Simple Storage Service (Amazon S3) bucket, CloudTrail must have write permissions for the bucket. When the DR region snapshot copy is completed, another state machine kicks off in the DR region. Checks for resource record sets that route DNS queries to AWS resources; these can be changed to alias resource record sets. Even though Amazon EBS volumes are replicated, failures can occur. Click here to return to Amazon Web Services homepage, AWS Trusted Advisor best practice checklist, Reserved Instance Optimization Check Questions, Amazon Virtual Private Cloud Network Administrator Guide, How many instances can I run in Amazon EC2. If a VPN has no active tunnels, charges for the VPN might still apply. For this example, assume that the primary region is us-west-2 and the DR region is us-east-2. While you can build your own backup tools using the built-in snapshot operations built in to many of the services that I listed above, creating an enterprise wide backup strategy … Checks the age of the snapshots for your Amazon Elastic Block Store (Amazon EBS) volumes (available or in-use).
