Is BYOC the next cloud initiative?

Tuesday, February 21st, 2012

While the notion of Bring Your Own Cloud (BYOC) may seem a bit far-fetched, Shadow IT, where users essentially bring unauthorized cloud services into business environments, has become an increasing corporate concern as highlighted in a recent CFO.com article. The risk of Shadow IT is that it compromises IT’s ability to maintain a standardized infrastructure across employees and business units, opening the door to potential security and reliability issues. In spite of this, there is a benefit in analyzing Shadow IT to understand why users adopt non-standard processes and what benefits existing IT could not deliver. It often pays to examine how employees creatively accomplish their goals in constrained environments and figure out how to accommodate those employees in a supportable fashion.

Shadow IT is not just limited to cloud. In a close parallel, many IT organizations that once outlawed all but one “approved” mobile device to access corporate accounts and email have loosened restrictions on accommodating multiple devices, moving closer to a BYOD (Bring Your Own Device) model. While pundits argue BYOD might transform IT into the “Wild West,” many organizations are finding a middle ground that offers users a selection of approved mobile devices for corporate access. With a standard set of security and reliability policies, users and business units gain the flexibility to meet their needs and optimize costs without having to consider Shadow IT.

So will trends toward BYOD now spawn a movement toward BYOC? Well, cloud solutions naturally require policies to protect data security and integrity and not all cloud solutions are suitable for enterprise use. In fact, it’s best to be wary of consumer-oriented solutions. On the other hand, the adoption of cloud solutions by many businesses emphasizes the immediate benefits they offer, including:

  1. Faster provisioning of resources. Traditional IT requests may take days or weeks to service due to competing priorities or delays in procurement and deployment.
  2. Overcoming capital spending limits. Subscription and pay-per-use models enable access to resources on an ongoing basis, avoiding capital spending limits and often falling under a separate opex budget
  3. Meeting variable resource demands. Demand for IT resources may change weekly, monthly or seasonally, calling for dynamic and elastic resource management often out of the realm of IT’s static processes

With these benefits in mind, how can businesses rationalize cloud solutions so that they meet corporate security, control and reliability requirements and avoid inhibiting the capabilities of their users? In the data storage realm, the answer can be found in cloud storage gateway products like CloudArray, offering choices across many supported public, private and hybrid cloud storage solutions with a set of overarching policies that meet corporate requirements for security, control, vendor lock prevention and reliability. With these solutions, users or business units have virtually all the cloud choices, options and policies they need to optimize their data storage deployments.

While BYOC is an unlikely IT initiative in the near term, businesses can benefit greatly today from standardizing on a set of efficient cloud options that deliver new levels of IT flexibility.

A New Cloud Storage Gateway Has Sprouted

Thursday, January 26th, 2012

You may have seen Amazon’s announcement of the AWS Storage Gateway beta here, here, and here. Truth be told, the cloud storage gateway market is starting to catch fire.

Amazon’s move validates the need for an iSCSI cloud storage gateway to easily deliver cloud storage into business environments and acknowledges that integration through APIs is not a process businesses will easily embrace. The deeper implication is that gateways facilitate the adoption of cloud storage as an alternative to on-premise or off-premise traditional storage, helping Amazon tap into a large multi-billion dollar data storage market. Does this mean more cloud providers may want to offer a gateway in the future? You bet.

There’s a lot of product differentiation between AWS Gateway and existing storage gateway products like CloudArray. Caching, performance, encryption, deduplication, compression, disaster recovery, high availability, ease of use, administration, storage capacity are all points of comparison one should consider. I’m sure there will be plenty published by users comparing hands-on experiences, so I won’t dive into deeper details here beyond mentioning one fly in the ointment: the AWS Gateway supports only one cloud provider.

Whether it’s purchasing servers or storage, businesses naturally prefer to have choices. And our cloud storage experience has been similar with customers preferring to have the flexibility to choose from a broad array of cloud providers including  Amazon, AT&T, Nirvanix, Rackspace, HP Cloud and PEER1 to name a few. Additionally, we are seeing increased interest in private clouds like OpenStack, EMC Atmos, Mezeo, Nirvanix, Scality and some businesses are even using existing storage as a starting point. If you plan to use multiple providers, are considering private cloud or at least want the flexibility to keep those options open in the future, a multi-provider gateway is a better solution.

Bottom line? Amazon’s announcement further positions cloud storage as a viable alternative to traditional on-premise and off-premise solutions. It presents one more way for businesses to easily connect to Amazon cloud storage and having more gateway choices is always a win for the customer. For customers seeking a robust, enterprise-class feature set and the industry’s broadest choice of public and private cloud providers, solutions like CloudArray continue to be the best option.

Dispelling 5 Myths About Cloud Storage

Sunday, October 16th, 2011

If you are considering cloud storage for storing business data, you may have questions regarding control and security. The truth is that not all cloud storage solutions are created equal, but when you choose an enterprise-class gateway solution to enable on-premise access to cloud storage, you not only stay in control of your data — you benefit from a level of security that rivals local storage.

With today’s cloud storage solutions ranging from consumer-grade to enterprise-class, offering huge variations in security, availability and performance, it’s really no wonder why confusion persists. In the interest of clearing the confusion, I think it’s time to debunk a number of common myths and misconceptions about cloud storage deployments for businesses. To do that, I’ve listed 5 familiar objections and myths about cloud storage that are addressed by enterprise-class cloud storage gateways:

Myth #1: It’s not secure enough

Data in the cloud can’t be safe, can it?

With cloud storage gateways offering the option of at-rest AES data encryption with locally managed keys along with fully encrypted data transfers, your data may be safer stored in the cloud rather than stored locally without encryption. Additionally, by storing encryption keys locally and separately from the cloud provider, you can even protect against an attempted breach on the cloud provider side (by let’s say a rogue employee) without exposure of data.

But what if your organization’s compliance requirements prevent you from storing any data outside your firewall? In that case, there are a number of private cloud offerings that can be deployed on-premise – EMC, Mezeo, Nirvanix, Scality and OpenStack to name a few. Even if your data must stay within your firewall, there is no reason to overlook the benefits of cloud storage.

Myth #2: It’s too complicated

I need to invest time learning new cloud storage APIs and porting applications.

With a cloud storage gateway solution, particularly one that is software-based, you can access storage capacity that will accommodate multiple Petabytes of data within minutes. There are no APIs to learn and no required changes to existing applications.

Think about that.  Traditionally, if you want to bring multiple Petabytes of storage capacity into your existing environment, you arrange a “fork-lift” of racks of storage equipment. Not only is that complicated, but what’s worse is that that infrastructure will only typically last 3-5 years. Soon, you’ll be right back into the next storage hardware upgrade cycle.

Myth #3: My data will be locked into the cloud

At least if I wait, I won’t run the risk of locking into the wrong cloud provider.

With dozens of cloud storage providers ranging from public to private to open-source clouds available today, cloud storage gateways offer you the flexibility to choose the provider that’s right for you.  In fact, you can even choose multiple providers simultaneously or switch from one to another. With open access to a growing ecosystem of providers, there is no reason to wait.

Be sure to invest in a gateway that is not locked into a single provider and is not single purpose. Instead, look for a gateway that can store backups, archives or even copies of primary data across a broad choice of providers simultaneously.

Myth #4: Why add risk? Maintaining the status quo is the safest bet

The folks who designed our existing storage environment didn’t need the cloud. Why do we?

Often, the status quo is a compromise that doesn’t include a robust disaster recovery solution, placing your entire business at risk. Perhaps the status quo involves shipping unencrypted tapes offsite as a first line of disaster recovery.  Think about the last time you ran a disaster drill and ask yourself – how quickly can I get my business back up and running? With enterprise-class cloud storage gateways, it’s simple to store data offsite for disaster recovery, with instant access from virtually anywhere.

You may consider local storage infrastructure relatively risk-free. However, the continuous purchase and retirement of on-premise storage arrays creates business risk on a regular basis, introducing complex and costly migration operations into the business. Maintenance windows, long migrations, and even policy changes can be particularly disruptive.

Myth #5: What if I work myself out of a job?

No one ever lost their job sticking with local storage infrastructure.

This particular argument has a knack for resurfacing with all new technologies. While cloud compute and storage have become very powerful tools for augmenting existing IT infrastructure, they still require skillful deployments that follow IT best practices.  The benefit of offloading the infrastructure to the provider is that it significantly reduces some of the more cumbersome IT tasks around infrastructure management. However, the task of architecting and deploying a supportable solution still remains.

Consider instead the consequences of inaction. Ignoring cloud infrastructure options available today may put your business at risk of being overtaken by more nimble competitors who are, in fact, leveraging the cloud, streamlining their operations, and improving their productivity. You may indeed work yourself out of a job in a way you may not have quite envisioned.

Bottom line? Enterprise-class cloud storage gateways have come a long way and address the risks of cloud storage deployments, making integration seamless and enabling huge cost and administrative savings. If you haven’t kept abreast of recent advances, you may want to set some time aside to revisit how enterprise-class gateways, like CloudArray, are making it amazingly easy to start augmenting your IT infrastructure.

6 Key Features of Cloud Storage Gateways (On-ramps or Enablers)

Monday, February 28th, 2011

Are you considering cloud storage for your business?  There are many reasons you should.  Using innovative cloud technology, IT is solving data storage problems in new ways. Whether it’s for off-site data protection, disaster recovery or just storage capacity expansion, the pay-as-you go model pioneered by a number of cloud storage providers can be very compelling.

Rather than use cloud storage directly by writing to custom APIs, building your own security policies and architecting a performance framework to meet application needs, you may find that on-premise cloud storage software or hardware (i.e. gateways, on-ramps, enablers) make integration simpler.  Purchasing a product that handles security, performance, data reduction and plug-and-play integration can significantly accelerate and simplify deployment.

With a handful of gateway products already on the market that can connect your on-premise environment to cloud storage, a natural question may (or should) be “what is the difference between these products?” above and beyond the aforementioned functionality.

To answer this, we’ve put together a list of 6 differentiating features you should consider when choosing a cloud storage gateway:

1) Dynamic caching policies to meet application needs:  A monolithic cloud storage cache may not be able to handle the performance needs for all applications. A backup application may benefit from a cache consisting of low-cost storage optimized for large sequential access, while an NTFS file system may benefit more from an SSD-based cache, optimized for smaller, more randomized access. Each application may require more or less cache over time. Having application-specific caching policies that are dynamic means you can meet needs of different applications using a single solution.

2) Option to replicate a local copy to the cloud: Some vendors argue that having a full local copy defeats the purpose of cloud storage – not at all true! Imagine replacing a real-time replicated secondary site requiring hardware, infrastructure and maintenance costs with a pay-as-you-go cloud! Or imagine not having a secondary site to begin with and now finding a 2-site replication solution within easy reach. This is a very compelling business proposition, particularly for transactional applications that require a full local copy for latency reasons.

3) In-cloud snapshots: Snapshots are rapidly becoming a key part of modernized backup and, when using the cloud, it is important to find out whether a gateway solution offers snapshots. If yes, are the snapshots copy-on-write and on-premise, meaning potential bandwidth thrashing between the local site and the cloud? Or are the snapshots in-cloud, redirect-on write, meaning no bandwidth penalty or performance penalty and readily available in case of disaster? If you have the option of the latter, you may have gathered that it is far superior.

4) Block and file-level access: It’s amazing to hear arguments from vendors trying to convince users that file access is better than block access for cloud gateways. The reality is that there are advantages to file access and advantages to block access. Supporting both means supporting that widest variety of operating systems, file systems and applications; and there is no longer any argument. Hint: having native block access (like iSCSI) means you can support both.

5) “Zero-friction” entry point to cloud storage: Deploying cloud storage should not mean continuing to spend additional CapEx/OpEx associated with traditional storage infrastructure and incurring the same 3-yr upgrade cycles.  Sure, there are advantages to optimized hardware appliances for accessing cloud storage, but only when needs and budget dictate. A choice of software, hardware and subscription models  with upgrade paths between each are the ideal way to start using cloud storage with minimal risk/cost and the ability to grow.

6) In-cloud disaster recovery and Compute-Anywhere capability: Once your data is in the cloud, you can access it anywhere, but how about in the cloud? Why not be able to leverage unlimited pay-as-you-go cloud compute cycles for disaster recovery or test. Beyond disaster recovery, your data or snapshots of data can and should “work” for you in the cloud. You can even leverage Big Data without dedicated processing resources by using cloud compute. Think about a vision of a hybrid data center and how this capability can enhance IT.

In summary, all cloud gateways, on-ramps, or enablers are not equal and it takes looking beyond  the similarities in features to understand whether they will meet the needs specific to your environment and grow to meet your future needs. It pays to look under the covers before purchasing…

Perhaps you have found a cloud storage solution that has all of these features. If you haven’t, we suggest you consider a cloud storage solution that does….
