Pre-Warming of EBS Volumes is not necessary

A number of people have asked me about pre-warming of new EBS volumes. I do realise that there are a lot of courses and exam dumps out there stating this is necessary. In fact it is not necessary with new volumes and if you answer this incorrectly you will lose valuable marks on the exam.

The only situation where preparation is required before access is with volumes that were restored from a snapshot:

"New EBS volumes receive their maximum performance the moment that they are available and do not require initialization (formerly known as pre-warming). However, storage blocks on volumes that were restored from snapshots must be initialized (pulled down from Amazon S3 and written to the volume) before you can access the block." Initializing Amazon EBS Volumes

When in doubt read the docs

AWS Certificate Manager rolling out to new regions

Previously you would need buy your SSL certificates outside of AWS and then convert them to the format for AWS and then upload to your ELB. Life is much easier now with AWS Certficate Manager that provides this service along with the cetificates for free! How cool is that?

The service has been rolled out to most regions so you may get a question on it in the exam.

AWS Certificate Manager is a service that lets you easily provision, manage, and deploy Secure Sockets Layer/Transport Layer Security (SSL/TLS) certificates for use with AWS services. SSL/TLS certificates are used to secure network communications and establish the identity of websites over the Internet. AWS Certificate Manager removes the time-consuming manual process of purchasing, uploading, and renewing SSL/TLS certificates. With AWS Certificate Manager, you can quickly request a certificate, deploy it on AWS resources such as Elastic Load Balancers or Amazon CloudFront distributions, and let AWS Certificate Manager handle certificate renewals. SSL/TLS certificates provisioned through AWS Certificate Manager are free. You pay only for the AWS resources you create to run your application.

ECS Auto Service Scaling

Watch for this on the exam! An ECS tutorial will be released with the SysOps videos.

Amazon EC2 Container Service Supports Automatic Service Scaling

Amazon EC2 Container Service (Amazon ECS) can now automatically scale container-based applications by dynamically growing and shrinking the number of tasks run by an Amazon ECS service.

Previously, when your application experienced a load spike you had to manually scale the number of tasks in your Amazon ECS service.
Now, you can automatically scale an Amazon ECS service based on any Amazon CloudWatch metric. For example, you can use CloudWatch metrics published by Amazon ECS, such as each service’s average CPU and memory usage. You can also use CloudWatch metrics published by other services or use custom metrics that are specific to your application. For example, a web service could increase the number of tasks based on Elastic Load Balancing metrics like SurgeQueueLength, while a batch job could increase the number of tasks based on Amazon SQS metrics like ApproximateNumberOfMessagesVisible.

New EC2 instance X1

Watch out for this on the exam!

X1 instances, the largest Amazon EC2 memory-optimized instance with 2 TB of memory

X1 instances extend the elasticity, simplicity, and cost savings of the AWS cloud to enterprise-grade applications with large dataset requirements. X1 instances are ideal for running in-memory databases like SAP HANA, big data processing engines like Apache Spark or Presto, and high performance computing (HPC) applications. X1 instances are certified by SAP to run production environments of the next-generation Business Suite S/4HANA, Business Suite on HANA (SoH), Business Warehouse on HANA (BW), and Data Mart Solutions on HANA on the AWS cloud.
X1 instances offer 2 TB of DDR4 based memory, 8x the memory offered by any other Amazon EC2 instance. Each X1 instance is powered by four Intel® Xeon® E7 8880 v3 (Haswell) processors and offers 128 vCPUs. In addition, X1 instances offer 10 Gbps of dedicated bandwidth to Amazon Elastic Block Store (Amazon EBS) and are EBS-optimized by default at no additional cost.
