AWS US East (Ohio) Region now Open

AWS

As part of Amazon ongoing plan to expand the AWS footprint, amazon has announced their new US East (Ohio) Region which is now available. 

 In conjunction with the existing US East (Northern Virginia) Region, AWS customers in the Eastern part of the United States have fast, low-latency access to the suite of AWS infrastructure services.

The Details

The new AWS Ohio Region supports Amazon Elastic Compute Cloud (EC2) and related services including Amazon Elastic Block Store (EBS), Amazon Virtual Private Cloud, Auto Scaling, Elastic Load Balancing, NAT Gateway, Spot Instances, and Dedicated Hosts.

It also supports (deep breath) Amazon API Gateway, Amazon Aurora, AWS Certificate Manager (ACM), AWS CloudFormation, Amazon CloudFront, AWS CloudHSM, Amazon CloudWatch (including CloudWatch Events and CloudWatch Logs), AWS CloudTrail, AWS CodeCommit, AWS CodeDeploy, AWS CodePipeline, AWS Config, AWS Database Migration Service, AWS Direct Connect, Amazon DynamoDB, EC2 Container Registy, Amazon ECS, Amazon Elastic File System, Amazon ElastiCache, AWS Elastic Beanstalk, Amazon EMR, Amazon Elasticsearch Service, Amazon Glacier, AWS Identity and Access Management (IAM), AWS Import/Export Snowball, AWS Key Management Service (KMS), Amazon Kinesis, AWS Lambda, AWS Marketplace, Mobile Hub, AWS OpsWorks, Amazon Relational Database Service (RDS), Amazon Redshift, Amazon Route 53, Amazon Simple Storage Service (S3), AWS Service Catalog, Amazon Simple Notification Service (SNS), Amazon Simple Queue Service (SQS), AWS Storage Gateway, Amazon Simple Workflow Service (SWF), AWS Trusted Advisor, VM Import/Export, and AWS WAF.

The Region supports all sizes of C4, D2, I2, M4, R3, T2, and X1 instances. As is the case with all of our newer Regions, instances must be launched within a Virtual Private Cloud (read Virtual Private Clouds for Everyone to learn more).

Well Connected

Here are some round-trip network metrics that you may find interesting (all names are airport codes, as is apparently customary in the networking world; all times are +/- 2 ms):

• 12 ms to IAD (home of the US East (Northern Virginia) Region).
• 20 ms to JFK (home to an Internet exchange point).
• 29 ms to ORD (home to a pair of Direct Connect locations hosted by QTS and Equinix and another exchange point).
• 91 ms to SFO (home of the US West (Northern California) Region).

With just 12 ms of round-trip latency between US East (Ohio) and US East (Northern Virginia), you can make good use of unique AWS features such as S3 Cross-Region Replication, Cross-Region Read Replicas for Amazon Aurora, Cross-Region Read Replicas for MySQL, and Cross-Region Read Replicas for PostgreSQL.

Data transfer between the two Regions is priced at the Inter-AZ price ($0.01 per GB), making your cross-region use cases even more economical.

Also on the networking front, we have agreed to work together with Ohio State University to provide AWS Direct Connect access to OARnet. This 100-gigabit network connects colleges, schools, medical research hospitals, and state government across Ohio.

This connection provides local teachers, students, and researchers with a dedicated, high-speed network connection to AWS.

14 Regions, 38 Availability Zones, and Counting

Today’s launch of this 3-AZ Region expands our global footprint to a grand total of 14 Regions and 38 Availability Zones. We are also getting ready to open up a second AWS Region in China, along with other new AWS Regions in Canada, France, and the UK.

Since there’s been some industry-wide confusion about the difference between Regions and Availability Zones of late, I think it is important to understand the differences between these two terms. Each Region is a physical location where we have one or more Availability Zones or AZs.

Each Availability Zone, in turn, consists of one or more data centers, each with redundant power, networking, and connectivity, all housed in separate facilities.

Having two or more AZ’s in each Region gives you the ability to run applications that are more highly available, fault tolerant, and durable than would be the case if you were limited to a single AZ.
