Amazon launches high-performance SSD instances to boost cloud power for database apps

 This will allow customers to run demanding data-driven applications in the cloud without the need for costly up-front capital investments. The availability of solid state storage, which is faster and more expensive than more traditional spinning disks, and has become a battleground with more companies adding the option as the price for SSDs falls, even in the laptops, and making them ideally suited for transaction processing,and mobile and streaming applications that require low latency access to storage systems that can deliver tens of thousands of IOPS.

 Netflix which is the largest commercial operation in the cloud must be very happy to hear this. If you ask me i don’t trust a hard disk drive.

Instance configuration that Amazon has just added:

High I/O Quadruple Extra Large Instance

60.5 GB of memory
35 EC2 Compute Units (16 virtual cores*)
2 SSD-based volumes each with 1024 GB of instance storage
64-bit platform
I/O Performance: Very High (10 Gigabit Ethernet)
Storage I/O Performance: Very High**
API name: hi1.4xlarge

*8 cores + 8 hyperthreads for 16 virtual cores

 

**Using Linux paravirtual (PV) AMIs, High I/O Quadruple Extra Large instances can deliver more than 120,000 4 KB random read IOPS

and between 10,000 and 85,000 4 KB random write IOPS (depending on active logical block addressing span) to applications.

For hardware virtual machines (HVM) and Windows AMIs, performance is approximately 90,000 4 KB random read IOPS and between 9,000

and 75,000 4 KB random write IOPS. The maximum sequential throughput on all AMI types (Linux PV, Linux HVM, and Windows)

per second is approximately 2 GB read and 1.1 GB write.

For those who want “Hard Disk Drive Vs SSD”

Like a hard drive, an SSD is a device for storing information. But unlike a hard drive, it doesn’t have any moving parts.

Today’s SSD are built with flash memory — the same stuff that stores data and applications on your iPhone.

These drives have been around for years, but they’ve been slow to make headway in the real world, in part because

they’re more expensive than traditional hard drives. A 300GB flash drive sells for around $500, whereas a comparable

hard drive is closer to $100. A 3 terabyte hard drive — which is about ten times larger — sells for around $350.
