Newest Cloud Storage Enabler

I was fielding an inquiry from one of my engineers and thought I'd share it, as it's probably a common question, esp. as we continue to see Cloud awareness spread, while the network barriers to external Cloud service adoption remain. Enjoy.

Hi Mike,
I'm interested in Cirtas, because a user asked me. What do you think of this kind of storage?

This is a very valuable solution. Much of 'Cloud storage' is not useful for companies for at least a few key reasons:

1) Security -- It's the #1 inhibitor to using external cloud services. Customers are worried that their data will be compromised either in transit outside of the corporate firewall, or after it's been stored, especially within a multi-tenant hosting environment.

2) Performance -- The second biggest problem with hosting your data in the cloud is that it's far away from the applications and users. So the distance between you and your data creates latency as well as other common WAN issues such as jitter, lost packets, etc. This is why we've seen much of cloud storage being for deep archiving or uses where you don't care how long it takes to either put or retrieve your data, such as email archiving for regulatory reasons.

3) The need to change your application -- Many providers, even those using brand name enterprise-class storage hardware such as EMC Atmos, are only allowing access via a RESTful API. This means that the customer needs to write an application that uses this API in order to store and access the data, and for all intents and purposes, limits the use of that cloud storage for web application media and data.

Cirtas, which just launched publically, is a great example of what I call a Cloud Storage Enabler in that they allow customers to overcome these barriers to adopting the external cloud. Their product, Bluejet, encrypts your data so it's secure both in transit and at-rest. It accelerates the transit with data compression and deduplication. And it emulates local storage, so it looks like any NFS/CIFS target to your applications and users. Cirtas is one of a number of companies with similar Cloud Enabler solutions - you should also consider Nasuni, TwinStrata, Panzura and StorSimple.

Thanks, and good luck,

Cloud Network Optimization validated

With the explosive growth of the Cloud Services market, exceeding $68 billion this year, it was obvious to expect lots of innovation in and around this space.  I had been mostly blogging about efforts in the Cloud Infrastructure and Storage space, and was seeing a microcosm of this opportunity with new classes of optimized gear to speed and secure the links from the customer to the cloud.

We recently have witnessed the emergence of Cloud gateways that appear as local NAS but act as intelligent controllers that cache, optimize, encrypt and convert data from the LAN out to the Storage cloud. Along with TwinStrata, Cirtas, StorSimple, and Nasuni, we can now add Panzura to this vendor list.

But I still expected to see a pure-play Cloud Network product in this area.  A device that performed the caching, dedupe, and encryption of a WAN opt. appliance but specifically aimed at datacenter-to-cloud traffic, where the protocols and acceleration are tweaked for storage data and larger pipes. It would be a network device, not a storage device, thus complementing new products such as EMC VPLEX to speed storage virtualization between data centers and enabling use cases such as VMotion over distance.  I had assumed an established network player would be first to meet this need, but a new player, Infineta, took the brass ring.

Infineta has been very distinct in their positioning, focusing on datacenter to datacenter and not branch office traffic which is the established realm of Riverbed and traditional WAN optimization.  And they released a cool new video on youtube. 

It's ultimately up to the analysts as to how the markets get defined, but with this latest product entry, I'm considering Cloud Storage Networking to be a validated market.  For IT organizations, now's the time to start thinking how you can use these new products to safely and cost-effectively transition archival and nearstore data out to the Cloud.

Cloud Storage Optimization market

A new product category is shaping up in direct response to a new customer need.  As seen in recent stories like "What's keeping Data Storage Out of the Cloud?", companies want to use new Cloud Storage services from providers such as IBM, but they are concerned about the security, availability and cost of the required network connection.  Enter Cloud Storage Optimization.

To bridge this network gap customers face a number of sub-optimal alternatives:

1. Don't worry about it -- probably the most popular approach, which only works if you don't care about your job, or the value of the data going across the wire is so low that it's not a big deal if it takes forever for the transit, or it's hacked, or both.
2. Lease a private connection -- this is an option for 'too big to fail banks' or other major organizations where cost isn't an issue.  But for most companies, the incremental cost of the circuit eliminates the economic savings of the Cloud service.
3. Use a generic WAN optimization box -- Not a great solution as these are software-based appliances designed for lower-bandwidth branch-office connections and a broad mix of transactional data.  The Cloud Storage connection is really a SAN-like 'channel' which will be very data intensive, and will benefit from hardware-based compression and offload processing.  And similar to the private circuit, the cost of the WAN optimization appliance that supports the higher throughput needed for the Cloud storage will cost you more than your annual Cloud storage bill.

What we're seeing in response is an initial first step towards closing this market gap: a new category of Cloud Storage Optimization solutions, or Cloud Storage Gateways.  Representative companies include Cirtas, Twinstrata, Nasuni and StorSimple.  These are all start-ups who seem to be quickly gaining awareness and traction with companies and Cloud Service Providers.

The anatomy of a Cloud Storage Gateway is made of software that either resides within an x86 server (i.e. an appliance) or completely as software that can be deployed within a VM.  They typically are asymmetric (i.e. single-device) solutions often positioned as a NAS filer.  Typical capabilities include NAS-to-Cloud API emulation, WAN Optimization, Caching, In-transit Encryption and Data management features such as snapshots.  As software-based solutions they are flexible, and meant to be affordable and targeted to a more mid-market customer.  Similarly they are intended for not-overly-demanding throughput needs, as there is no purpose-built processor offload. 

For mid-market companies looking to add a Cloud tier of archival or similar offline data storage, these are products to consider.  For enterprises or companies who want to leverage Cloud storage as a nearstore alternative, you will want to wait for next-gen 'Cloud Networking' products built for high-throughput, hardware-assisted optimization, symmetric caching/network de-dupe capabilities, and that integrate with your existing network management framework.
