An Amazon Elastic Block Store (Amazon EBS) snapshot can now be copied inside or between AWS Regions and/or accounts, with a specified completion time ranging from 15 minutes to 48 hours. Meeting time-based compliance and business requirements for important workloads will be made easier with this. As an illustration:

Testing: As part of your Test Data Management (TDM) strategy, test new data by promptly distributing it.

Development: Regularly and frequently send your developers updated snapshot data.

Disaster Recovery: In disaster recovery, make sure that important snapshots are duplicated to fulfill a Recovery Point Objective (RPO).

You can get reliable and consistent copies with this new capability, regardless of your use case. You can select the option and timing that best suits each scenario; this has no bearing on the functionality or dependability of regular copies.

Making a Copy of a Time-Based Snapshot

You can use the AWS Management Console, the copy-snapshot CLI, or the copy-snapshot API to make time-based snapshot copies.

Pick the source as normal and select Copy snapshot from the Action menu to produce a time-based snapshot. You selected the US-east-1 AWS Region as the destination, enter a description for the copy, click Enable time-based copy, and specify a 15-minute completion time because this is a time-sensitive snapshot:

The request will only be approved (and the copy will become pending) when you select Copy snapshot if your account’s throughput quotas haven’t surpassed the throughput used by other active copies you will be making to the destination region. If the account-level throughput quota has already been surpassed, an error message will appear in the console.

You may see the shortest possible copy duration for the photo by clicking the Launch copy duration calculator. You launch the calculator, input the throughput cap for my account, and select an assessment timeframe:

The calculator then determines the bare minimal amount of time you can finish by using past data gathered over the course of earlier snapshot copies. Using time-based copy and my current account throughput quota of 2000 MiB/second, you were able to copy 1,800,000 MiB in the last 24 hours. This would have taken roughly 15 minutes.

You can use the console to keep an eye on the copy’s progress while it’s happening, or you can call DescribeSnapshots and look at the result’s progress field. The Amazon EventBridge events listed below can also be used to perform actions (the event is broadcast in the destination area if the copy operation spans regions):

copySnapshot: Sent following the completion of the copy process.

copyMissedCompletionDuration: Sent if the copy is still pending when the deadline has passed.

Things to Keep in Mind

And it’s pretty much that simple! You should be aware of the following regarding time-based snapshot copies:

CloudWatch Metrics: The SnapshotCopyBytesTransferred metric, which is released in the destination area, indicates the volume of data measured in bytes that is transmitted between the source and destination regions.

Duration: This depends on the number of copies and can vary from 15 minutes to 48 hours in 15-minute increments.

Concurrency: If you are copying a snapshot and you start a second copy of it in the same location, the second copy’s time begins when the first one is finished.

Throughput: Each source-destination pair has a default throughput limit of 2000 MiB/second. Through the AWS Support Center, you can request an increase if you want more throughput to reach your RPO. The throughput is limited to 500 MiB/second per snapshot and cannot be raised.

What is Amazon Route 53

A dependable and economical method of connecting end users to Internet applications

Sharing and then assigning numerous DNS resources to each Amazon Virtual Private Cloud (Amazon VPC) can be quite time-consuming if you are managing numerous accounts and Amazon VPC resources. You may have even gone so far as to create your own orchestration layers in order to distribute DNS configuration throughout your accounts and VPCs, but you frequently run into limitations with sharing and association.

Amazon Route 53 Resolver DNS firewall

With great pleasure, AWS now provide Amazon Route 53 Profiles, which enable you to centrally manage DNS for all accounts and VPCs in your company. Using Route 53 Profiles, you may apply a standard DNS configuration to several VPCs in the same AWS Region. This configuration includes Amazon Route 53 private hosted zone (PHZ) associations, Resolver forwarding rules, and Route 53 Resolver DNS Firewall rule groups. You can quickly and simply verify that all of your VPCs have the same DNS setup by using Profiles, saving you the trouble of managing different Route 53 resources. It is now as easy to manage DNS for several VPCs as it was for a single VPC.

Because Profiles and AWS Resource Access Manager (RAM) are naturally connected, you can exchange Profiles between accounts or with your AWS Organizations account. By enabling you to create and add pre-existing private hosted zones to your Profile, Profiles effortlessly interacts with Route 53 private hosted zones. This means that when the Profile is shared across accounts, your organizations will have access to the same settings. When accounts are initially provisioned, AWS CloudFormation enables you to utilize Profiles to define DNS settings for VPCs regularly. You may now more effectively manage DNS settings for your multi-account environments with today’s release.

Amazon Route 53 benefits

Automatic scaling and internationally distributed Domain Name System (DNS) servers ensure dependable user routing to your website

Amazon Route 53 uses globally dispersed Domain Name System (DNS) servers to provide dependable and effective end-user routing to your website. By dynamically adapting to changing workloads, automated scaling maximises efficiency and preserves a flawless user experience.

With simple visual traffic flow tools and domain name registration, set up your DNS routing in a matter of minutes

With simple visual traffic flow tools and a fast and easy domain name registration process, Amazon Route 53 simplifies DNS routing configuration. This makes it easier for consumers to manage and direct web traffic effectively by allowing them to modify their DNS settings in a matter of minutes.

To cut down on latency, increase application availability, and uphold compliance, modify your DNS routing policies

Users can customize DNS routing settings with Amazon Route 53 to meet unique requirements including assuring compliance, improving application availability, and lowering latency. With this customization, customers can optimize DNS configurations for resilience, performance, and legal compliance.

How it functions

A DNS (Domain Name System) online service that is both scalable and highly available is Amazon Route 53. Route 53 links user queries to on-premises or AWS internet applications.Image credit to AWS

Use cases

Control network traffic worldwide

Easy-to-use global DNS features let you create, visualize, and scale complicated routing interactions between records and policies.

Construct programmes that are extremely available

In the event of a failure, configure routing policies to predetermine and automate responses, such as rerouting traffic to different Availability Zones or Regions.

Configure a private DNS

In your Amazon Virtual Private Cloud, you can assign and access custom domain names (VPC). Utilise internal AWS servers and resources to prevent DNS data from being visible to the general public.

Which actions can you perform in Amazon Route 53

The operation of Route 53 Profiles

You go to the AWS Management Console for Route 53 to begin using the Route 53 Profiles. There, you can establish Profiles, furnish them with resources, and link them to their respective VPCs. Then use AWS RAM to share the profile you made with another account.

To set up my profile, you select Profiles from the Route 53 console’s navigation pane, and then you select Create profile.

You will optionally add tags to my Profile configuration and give it a pleasant name like MyFirstRoute53Profile.

The Profile console page allows me to add new Resolver rules, private hosted zones, and DNS Firewall rule groups to my account or modify the ones that are already there.

You select which VPCs to link to the Profile. In addition to configuring recursive DNSSEC validation the DNS Firewalls linked to my VPCs’ failure mode, you are also able to add tags. Additionally, you have the ability to decide which comes first when evaluating DNS: Profile DNS first, VPC DNS second, or VPC DNS first.

Up to 5,000 VPCs can be linked to a single Profile, and you can correlate one Profile with each VPC.

You can control VPC settings for different accounts in your organization by using profiles. Instead of setting them up per-VPC, you may disable reverse DNS rules for every VPC that the Profile is connected to. To make it simple for other services to resolve hostnames from IP addresses, the Route 53 Resolver automatically generates rules for reverse DNS lookups on my behalf. You can choose between failing open and failing closed when using DNS Firewall by going into the firewall’s settings. Additionally, you may indicate if you want to employ DNSSEC signing in Amazon Route 53 (or any other provider) in order to enable recursive DNSSEC validation for the VPCs linked to the Profile.

Assume you can link a Profile to a VPC. What occurs when a query precisely matches a PHZ or resolver rule that is linked to the VPC’s Profile as well as one that is related with the VPC directly? Which DNS settings, those from the local VPCs or the profiles, take priority? In the event that the Profile includes a PHZ for example.com and the VPC is linked to a PHZ for example.com, the VPC’s local DNS settings will be applied first. The most specific name prevails when a name query for a conflicting domain name is made (for instance, the VPC is linked to a PHZ with the name account1.infra.example.com, while the Profile has a PHZ for infra.example.com).

Using AWS RAM to share Route 53 Profiles between accounts

You can share the Profile you made in the previous part with my second account using AWS Resource Access Manager (RAM).

On the Profiles detail page, you select the Share profile option. Alternatively, you may access the AWS RAM console page and select Create resource share.

You give your resource share a name, and then you go to the Resources area and look for the “Route 53 Profiles.” You choose the Profile under the list of resources. You have the option to add tags. Next is what you select.

RAM controlled permissions are used by profiles, enabling me to assign distinct permissions to various resource types. The resources inside the Profile can only be changed by the Profile’s owner, the network administrator, by default. Only the contents of the Profile (in read-only mode) will be accessible to the recipients of the Profile, which are the VPC owners. The resource must have the required permissions attached to it in order for the Profile’s recipient to add PHZs or other resources to it. Any resources that the Profile owner adds to the shared resource cannot be edited or removed by recipients.

You choose to allow access to my second account by selecting Next, leaving the default settings.

You select Allow sharing with anyone on the following screen, type in the ID of my second account, and click Add. Next, You select that account ID under Selected Principals and click Next.

You select Create resource share on the Review and create page. The creation of the resource sharing is successful.

You, now navigate to the RAM console using your other account, which you share your profile with. You select the resource name you generated in the first account under the Resource sharing section of the navigation menu. You accept the offer by selecting Accept resource share.

And that’s it! now select the Profile that was shared with you on your Amazon Route 53Profiles page.

The private hosted zones, Resolver rules, and DNS Firewall rule groups of the shared profile are all accessible to you. You are able to link this Profile to the VPCs for this account. There are no resources that you can change or remove. As regional resources, profiles are not transferable between regions.

Amazon Route 53 availability

Using the AWS Management Console, Route 53 API, AWS CloudFormation, AWS Command Line Interface (AWS CLI), and AWS SDKs, you can quickly get started with Route 53 Profiles.

With the exception of Canada West (Calgary), the AWS GovCloud (US) Regions, and the Amazon Web Services China Regions, Route 53 Profiles will be accessible in every AWS Region.
