Amazon Elastic File System overview

Events

Amazon Web Services (AWS) has announced in April of this year, during AWS Summit San Francisco, the new storage service, the Amazon Elastic File System (EFS). This product, still in preview, will be lauched in June and will be available initially on regions US-West (Oregon), US-East (N. Virginia) e EU (Ireland).

AWS storage portfolio

AWS has already other 3 storage services the Amazon Simple Storage Service (S3), Amazon Elastic Block System (EBS) and Amazon Glacier. Let's briefly compare these services and the brand new EFS.

AWS storage services comparison
Service Storage type Access/latency Cost Access freq.
Amazon S3 Objects API's REST/Low latency $0,030 per GB-month High
Amazon EBS Blocks

Single EC2 instance /Lowest latency

$0.100 per GB-month High
Amazon Glacier Archive API's REST/High latency $0.010 per GB-month Low
Amazon EFS File System Multiple EC2 instances/low latency $0,300 per GB-month Alta

Amazon EFS features

EFS' main features are that the file system is elastic, scalable and can be shared between thousands of EC2 instances. This sharing is very simple and fully managed. It's simple to use because it provides standard file system semantics and it acts like any other file system that you can mount on your EC2 instance. You can mount it on many instances in an Amazon region and it will be automatically shared with any other instance in which you mounted the EFS. This way you garantee high durability and availability.

The EFS is completly scalable and eslastic and can grow up to PB. The elasticity is automatic, that means it's not necessary to require more or less disk space during your use. It has no minimum storage space to start using EFS.

Another important feature is the high performance. SSD-Based, EFS is designed to have high throughput, IOPS and low latency. These features are automatically scalable while your file system grows.

EFS security

EFS provides a tight control on storage data access. The security of EFS has 3 layers:

  1. Network: Only EC2 instances inside the same VPC can mount the file system.
  2. Security groups: It's possible to restrict which security groups that can access the EFS.
  3. User: Common file system permissions can be apllied to folders and files inside EFS.

How does it work? 

To access files into EFS on an EC2 instance it's necessary to mount the system. You have to create mount targets in each availability zone. Mount targets are EFS endpoints and have one IP address and a DNS name. When you create a EFS on AWS you receive these DNS names of each AZ. These names are used when you mount the file system on your EC2 instances. The figure shows the structure of EFS working flow.

EFS is in preview and as soon as we have access to the preview, we will demonstrate this tool.



















Amazon Web Services launches Frankfurt (Germany) region

Events

Amazon Web Services (AWS) launched today their second region in Europe, this time in Frankfurt, Germany. The new region already supports many services offered by AWS worldwide, including the traditional Elastic Compute Cloud (EC2)Elastic Block Storage (EBS)Auto ScalingElastic Load Balancing and Relational Database Service (RDS). Moreover, three new edge locations were included in Frankfurt for Route 53 and CloudFront.

Ireland and Frankfurt regions can now be used together to build multi-region applications with the assurance that all data are hosted in data centers within the European Union. The launch of a region in German soil is probably related to the restrictive data protection laws that companies in that country have to deal with, which limits what can be stored in data centers outside the country.

Tweets stream with semantic analysis - Twitter

September 18, thursday, 9h AM PST

Google is working to provide a new service called Google Cloud Dataflow. It will enable large scale processing of realt-time streaming data, like tweets, activities or events. It may be offered integrated with other Google Cloud services, like Cloud Storage, Big Query and Pub/Sub.

Eric Schmidt, Solutions Architect at Google, will present Google Cloud Dataflow and share how he analyzed the sentiment of millions of tweets streaming real-time from the World Cup in order to track fan response to events happening on the field. He'll show how he calculated average sentiment per team and per match, correlated sentiment with keywords of turning points in the games, and tied it all together with a timeline visualization that lets you track how global fans feel throughout the match.
