AWS Adds 12 Purpose Built EC2 Cloud Instances

By - Source: Toms IT Pro

AWS is a beast that continues to grow, and this most recent expansion sees 12 new EC2 Elastic MapReduce instance types and an entirely new EC2 instance category, the R3. Amazon is also adding new regional support for several instance types.

The AWS blog categorizes their new instance types into five functionality-based categories:

  • General Purpose (m3.xlarge and m3.2xlarge)
  • Compute-optimized (c3.xlarge, c3.2xlarge, c3.4xlarge and c3.8xlarge)
  • GPU (g2.2xlarge)
  • Memory-optimized (cr1.8xlarge)
  • Storage-optimized (i2.xlarge, i2.2xlarge, i2.4xlarge and i2.8xlarge)

The blog goes into some detail for several of the new types, detailing possible applications. First, the c3.8xlarge instance type is best suited for compute intensive applications, such as image or video processing. The c3.8xlarge totes 32 vCPUs, 60GiB of memory, 10 Gigabit connectivity and two 320GB SSDs for storage.

The i2.8xlarge falls under Amazon's storage-optimized specification and is ideal for analytics applications, such as Impala, Spark or Hbase. It utilizes 32vCPUs, 244GiB memory, eight 800GB SSDs, and a 10 Gigabit network connection.

Finally, the m3.2xlarge instance type is a general application instance that would suit any workload that doesn't require specialization in any one area (i.e. compute, storage, memory). M3.2xlarge instances run on 8 vCPUs, 30GiB of memory and two 80GB SSDs.

The new R3 EC2 instance category is designed for memory intensive applications. Amazon announced the new instance category at its annual AWS Summit in San Francisco on March 26, 2014.

Five different R3 instance setups are planned at the moment: r3.large, r3.xlarge, r3.2xlarge, r3.4xlarge, r3.8xlarge. These instance setups range from having 2 – 32 vCPUs, 15 – 244 GiB of memory, 32 – 640 GB of SSD storage, and will be priced from $0.175/hr - $2.800/hr. The r3.xlarge, r3.2xlarge and r3.4xlarge will be eligible to launch in EBS-Optimized form, meaning an increased I/O capacity. Only the r.3xlarge instance type will have 10 Gigabit networking connectivity.

New Regional Support

Amazon is extending regional support for three existing instance types:

  • The hs1.8xlarge is now available in US West (Oregon), Europe (Ireland), Asia Pacific (Tokyo), Asia Pacific (Singapore), and Asia Pacific (Sydney).
  • The hi1.4xlarge is now available in the US West (Oregon and Asia Pacific (Tokyo) regions.
  • The cc2.8xlarge is now available in the Asia Pacific (Tokyo) region.
