Hello, Cloud Gurus. Welcome back to another AWS This Week, where we find out what goodies AWS
have in store for us from the past seven days. I am your friendly neighborhood Jess Alvarez.
And today we talk about Redshift, learn about Resilience Hub and take a look at an upcoming
exam update. Stay tuned to hear the full story in this episode of AWS This Week.
Let's talk about Redshift, Amazon's data warehouse solution.
It uses SQL to analyze structured and semi-structured data across data warehouses,
operational databases, and data lakes using AWS-designed hardware and machine learning.
This solution now has two options to serialize transactions: Serializable and Snapshot Isolation.
Serializable can be used to implement strict serializability where a transaction could fail
if the result cannot be mapped to a serial order of the concurrently, or overlapping,
running transactions. Snapshot Isolation will allow high concurrency where concurrent
modifications to different rows in the same table would complete successfully. Both options
allow transactions to continue to operate on the latest committed version of the database.
Serializable is the default option for provisioned clusters, and serverless data warehouses will
use Snapshot Isolation as their default and are available in regions that Redshift is available.
I'll include some documentation on how you can change the defaults in the resources.
There are lots of new updates to AWS Resilience Hub. Resilience refers to the ability of your
applications to maintain availability and recover from disruptions within a specific time
and point (RTO and RPO). Resilience Hub provides a central location to define, validate, and track
the resilience of your applications to prevent any downtime caused by software, infrastructure,
or operational disruptions. It also provides actionable recommendations to improve resilience.
This solution now supports Amazon's Elastic Container Service, or ECS,
Route 53, Elastic Disaster Recovery, Backup, and can now use Terraform as a source to upload
applications. This means even more applications will be protected from disruptions. The Resilience
Hub's resilience score has also been updated. The score will now be calculated to reflect
a combination of operational recommendations and policy compliance. If that wasn't enough,
Resilience Hub now runs daily assessments on new applications
automatically. Manually activate this feature on any existing applications and deactivate it
whenever you'd like. These updates are available in every region that Resilience Hub is available.
Are you ready for the big news? Well, buh buh buh!
The Solutions Architect Professional certification is getting an update. The cert
will be updated to ensure its alignment with the Well-Architected Framework, AWS technical skills,
and cloud expertise. The exam can still be taken via a testing center, or online,
and is 75 questions long. You'll have 180 minutes to take this $300 exam, and will include multiple
choice and multiple response questions. Here are some important dates to remember: October 18th,
when registration opens for the new exam. November 14th is the last day you can take the current
exam. And then the following day, November 15th, is the first day you can take the updated exam.
Keep in mind that once you attain, or re-certify, the SA Pro cert, certs like the SA Associate will
automatically be renewed. Assuming you already have it. Check out the resources for the exam
guide and sample questions. Well then, I hope you enjoyed this episode of AWS This Week.
I'll include links and the resources to cover all the fancy new things we covered today.
